Description

この発明は、電動モータにより駆動対象物を駆動制御するアクチュエータ及びこのアクチュエータを用いてバルブを開閉制御するバルブ装置及びダンパを開閉制御するダンパ装置に関するものである。   The present invention relates to an actuator that drives and controls an object to be driven by an electric motor, a valve device that controls opening and closing of a valve using the actuator, and a damper device that controls opening and closing of a damper.

アクチュエータによるバルブ操作において、バルブの据え付け、点検、緊急時等には、手動操作によるバルブ開度の調整が必要とされる場合がある。このため、バルブの開閉制御を行う電動のアクチュエータでは、電動モータ等の駆動源とアクチュエータ出力軸との間のギアユニット内に電動操作と手動操作の切り替えを行うクラッチ機構を介在させている。   In valve operation by an actuator, adjustment of the valve opening by manual operation may be required during valve installation, inspection, emergency, etc. For this reason, in an electric actuator that controls opening and closing of a valve, a clutch mechanism that switches between an electric operation and a manual operation is interposed in a gear unit between a drive source such as an electric motor and an actuator output shaft.

図８は、手動と電動の操作切替用のクラッチ機構を有するアクチュエータを備えたバルブ装置を示す斜視図であり、図８（ａ）はアクチュエータ１００をバルブ１０１に取り付けた状態を示し、図８（ｂ）はバルブ１０１を全開にする手動操作例を示し、図８（ｃ）はバルブ１０１を閉状態とする手動操作例を示している。   FIG. 8 is a perspective view showing a valve device including an actuator having a clutch mechanism for manual and electric operation switching. FIG. 8A shows a state in which the actuator 100 is attached to the valve 101. FIG. FIG. 8B shows a manual operation example in which the valve 101 is fully opened, and FIG. 8C shows a manual operation example in which the valve 101 is closed.

図８に示すように、アクチュエータ１００は、ケーシングにバルブ開度メモリ１０４に沿って回動可能な手動操作レバー１０２、及びケーシングから突出させたクラッチボタン１０３を備える。なお、アクチュエータ１００のケーシング内は図示していないが、電動モータ等の駆動源、バルブ１０１の弁軸に連結された出力軸、及び駆動源からの駆動力を出力軸に伝えるギアユニットが設けられている。   As shown in FIG. 8, the actuator 100 includes a manual operation lever 102 that can rotate along a valve opening degree memory 104 on the casing, and a clutch button 103 that protrudes from the casing. Although not shown inside the casing of the actuator 100, a drive source such as an electric motor, an output shaft connected to the valve shaft of the valve 101, and a gear unit that transmits the driving force from the drive source to the output shaft are provided. ing.

バルブ１０１の開度調整を手動操作にて行う場合、図８（ｂ）、（ｃ）に示すように、クラッチボタン１０３を押下する（図８中に黒色矢印で示す）。これにより、ケーシング内のギアユニットと駆動源との機械的な結合が解除される。このとき、図８（ｂ）に示すバルブ開度メモリ１０４の開度１００の位置まで手動操作レバー１０２を回動させると、これに応じて出力軸が回転してバルブ１０１が全開状態になる。また、図８（ｃ）に示すように、バルブ開度メモリ１０４の開度０の位置まで手動操作レバー１０２を回動させると、これに応じて出力軸が逆方向に回転してバルブ１０１が閉状態になる。   When adjusting the opening degree of the valve 101 by manual operation, as shown in FIGS. 8B and 8C, the clutch button 103 is pressed (indicated by a black arrow in FIG. 8). Thereby, the mechanical coupling between the gear unit in the casing and the drive source is released. At this time, when the manual operation lever 102 is rotated to the position of the opening degree 100 of the valve opening degree memory 104 shown in FIG. 8B, the output shaft rotates according to this and the valve 101 is fully opened. Further, as shown in FIG. 8C, when the manual operation lever 102 is rotated to the position of the opening degree 0 in the valve opening degree memory 104, the output shaft is rotated in the reverse direction accordingly, and the valve 101 is moved. Closed.

このような手動操作用のクラッチ機構を有する従来のアクチュエータとしては、例えば特許文献１に開示されるものがある。特許文献１に開示されるアクチュエータでは、ケーシング内に設けたクラッチボタンの押圧ストロークでアクチュエータの電源オンオフすると共に、クラッチボタンの押圧操作に連動して上下動するクラッチ桿によりギアユニットの噛合ギア群の１つを離脱させる。これにより、出力軸の手動操作が可能になる。   As a conventional actuator having such a manual operation clutch mechanism, there is one disclosed in Patent Document 1, for example. In the actuator disclosed in Patent Document 1, the power of the actuator is turned on and off by the pressing stroke of the clutch button provided in the casing, and the meshing gear group of the gear unit is moved by the clutch rod that moves up and down in conjunction with the pressing operation of the clutch button. Remove one. This allows manual operation of the output shaft.

また、特許文献２には、クラッチ手段がオフの状態でバルブの手動操作が行われたことを前提として、タイマの動作を開始させると共に、バルブの開度を目標開度に調整する制御回路の作動を停止させ、且つタイマのタイムアップに基づいて制御回路の作動を復帰させる手段を具備するバルブ制御装置が開示されている。このバルブ制御装置では、手動で調節したバルブ開度を設定変更可能なタイマに設定されているタイムアップ時間まで保持することが可能である。   Patent Document 2 discloses a control circuit that starts a timer operation and adjusts the valve opening to a target opening on the premise that the valve is manually operated with the clutch means turned off. There is disclosed a valve control device including means for stopping the operation and returning the operation of the control circuit based on the time-up of the timer. In this valve control device, it is possible to hold the manually adjusted valve opening until the time-up time set in the timer whose setting can be changed.

一方、アクチュエータは、一定の速度でバルブの開度操作を行うことが一般的であるが、バルブの動作速度を変えたい場合がある。例えば、開く方向（流量が増加する）へは高速で、閉じる方向（流量が減少する）へは低速で動かしたいという要求がある。このような要求に対応するには、変速用のクラッチ機構（変速クラッチ）を設ける必要がある。   On the other hand, the actuator generally operates the opening degree of the valve at a constant speed, but there are cases where it is desired to change the operating speed of the valve. For example, there is a demand to move at high speed in the opening direction (in which the flow rate increases) and at low speed in the closing direction (in which the flow rate decreases). In order to meet such a demand, it is necessary to provide a clutch mechanism (shift clutch) for shifting.

図９は、手動操作用のクラッチ機構と変速用のクラッチ機構を有する従来のアクチュエータのギアユニットの構成例を示す図である。図９に示すアクチュエータは、電動モータ２００と出力軸２１０の間に介在させたギアユニット内に、電動操作と手動操作を切り替えるためのギアである電動／手動切替クラッチ２０２と、速度比の変更用ギアである変速クラッチ２０５とを設けた構成例を示している。この電動／手動切替クラッチ２０２と変速クラッチ２０５は、図９中の矢印で示すように上下動自在にギアユニット内に支持される。   FIG. 9 is a diagram illustrating a configuration example of a gear unit of a conventional actuator having a clutch mechanism for manual operation and a clutch mechanism for shifting. The actuator shown in FIG. 9 includes an electric / manual switching clutch 202 that is a gear for switching between electric operation and manual operation in a gear unit interposed between the electric motor 200 and the output shaft 210, and for changing the speed ratio. The example of a structure which provided the transmission clutch 205 which is a gear is shown. The electric / manual switching clutch 202 and the transmission clutch 205 are supported in the gear unit so as to be movable up and down as indicated by arrows in FIG.

電動／手動切替クラッチ２０２は、電動操作時（通常のアクチュエータ使用時）において、伝達ギア２０３と電動モータ２００の駆動軸に取り付けられた伝達ギア２０１とにそれぞれ噛み合った状態にある。この状態で電動モータ２００を駆動させると、その駆動力が伝達ギア２０３の後段のギアに順次伝達されて出力軸２１０が駆動する。   The electric / manual switching clutch 202 is in mesh with the transmission gear 203 and the transmission gear 201 attached to the drive shaft of the electric motor 200 during electric operation (when using a normal actuator). When the electric motor 200 is driven in this state, the driving force is sequentially transmitted to the subsequent gear of the transmission gear 203 to drive the output shaft 210.

手動操作時には、電動／手動切替クラッチ２０２を図９中に示す手動操作位置にシフトさせて伝達ギア２０１との噛み合いを解除する。これによって、電動／手動切替クラッチ２０２から後段のギアと電動モータ２００との機械的結合が解除されるので、手動操作レバー２０４を回動操作することにより出力軸２１０を手動操作することができる。   During manual operation, the electric / manual switching clutch 202 is shifted to the manual operation position shown in FIG. 9 to disengage the transmission gear 201. As a result, the mechanical coupling between the rear gear and the electric motor 200 is released from the electric / manual switching clutch 202, so that the output shaft 210 can be manually operated by rotating the manual operation lever 204.

また、変速クラッチ２０５は、例えば大径ギアと小径ギアが同軸に一体に形成された構造を有しており、図９に示す第１変速位置で出力軸側に隣接する第１変速ギア２０６と噛み合い、第２変速位置で出力軸側に隣接する第２変速ギア２０７と噛み合う。第１変速ギア２０６は第２変速ギア２０７より小径のギアであり、両者は伝達ギア２０８の上下に設けられる。伝達ギア２０８は、出力軸２１０に設けられた伝達ギア２０９と噛み合っている。これにより、第１変速位置と第２変速位置で異なる減速比で電動モータ２００の回転を出力軸２１０に伝えることができる。   Further, the transmission clutch 205 has a structure in which, for example, a large-diameter gear and a small-diameter gear are integrally formed coaxially, and the first transmission gear 206 adjacent to the output shaft side at the first transmission position shown in FIG. Engages with the second transmission gear 207 adjacent to the output shaft side at the second shift position. The first transmission gear 206 has a smaller diameter than the second transmission gear 207, and both are provided above and below the transmission gear 208. The transmission gear 208 meshes with a transmission gear 209 provided on the output shaft 210. Thereby, the rotation of the electric motor 200 can be transmitted to the output shaft 210 at different reduction ratios at the first shift position and the second shift position.

バルブの開閉制御等では、バルブの用途によって開閉動作の速度を速めたり、動作量が異なっても動作時間を維持したい場合がある。このため、バルブの開閉動作を制御するアクチュエータの動作速度を可変に設定できることが望まれる。   In valve opening / closing control, etc., there are cases where the opening / closing operation speed is increased depending on the use of the valve or the operation time is desired to be maintained even when the operation amount is different. For this reason, it is desired that the operating speed of the actuator for controlling the opening / closing operation of the valve can be variably set.

従来のアクチュエータにおいて、出力軸の回転速度を可変とするには、例えば図９に示す変速クラッチ２０５のような変速用のクラッチ機構をギアユニット内に新たに設けるか、若しくは電動モータ等の駆動源自体を速度可変にすること等が考えられる。   In the conventional actuator, in order to make the rotation speed of the output shaft variable, for example, a gear clutch mechanism such as a gear shift clutch 205 shown in FIG. 9 is newly provided in the gear unit, or a drive source such as an electric motor is provided. It is conceivable to make the speed itself variable.

しかしながら、例えば手動操作用のクラッチ機構を有するアクチュエータに対して変速用のクラッチ機構を設ける場合、図９に示すように部品点数が増えてギアユニット内の空間が占有され、アクチュエータが大型化、複雑化するという課題がある。また、駆動源を速度可変にするには、高価な速度制御回路やこれに対応した駆動源が必要であり、コスト的に不利である。   However, for example, when a clutch mechanism for shifting is provided for an actuator having a clutch mechanism for manual operation, the number of parts is increased as shown in FIG. There is a problem of becoming. Further, in order to make the drive source variable in speed, an expensive speed control circuit and a drive source corresponding to this are required, which is disadvantageous in terms of cost.

この発明は、上記のような課題を解決するためになされたもので、手動と電動の操作切り替え及び出力軸の変速を簡易な構成で実現することができるアクチュエータ及びこれを用いてバルブを開閉制御するバルブ装置及びダンパを開閉制御するダンパ装置を得ることを目的とする。   The present invention has been made to solve the above-described problems. An actuator capable of switching between manual and electric operation and shifting of an output shaft with a simple configuration, and a valve opening / closing control using the actuator. It is an object of the present invention to provide a valve device that performs the above and a damper device that controls opening and closing of the damper.

この発明に係るアクチュエータは、同軸に一体で回転する複数のギアから構成され、中心軸に沿って移動可能に取り付けられた手動／変速クラッチギアと、手動／変速クラッチギアと噛み合って電動モータからの回転トルクを伝達する前段側伝達ギア部と、手動／変速クラッチギアと噛み合って異なる減速比を与える複数のギアを含んで構成され、電動モータからの回転トルクを出力軸側に伝達する後段側伝達ギア部と、手動／変速クラッチギアの中心軸に沿った移動操作により、前段側伝達ギア部又は後段側伝達ギア部のうちのいずれか一方と手動／変速クラッチギアとの噛み合わせ解除と、手動／変速クラッチギアと後段側伝達ギア部との間で選択的にギアの噛み合わせとを行うクラッチギア切替手段とを備えるものである。   The actuator according to the present invention is composed of a plurality of gears that rotate coaxially and integrally, a manual / transmission clutch gear that is movably mounted along a central axis, and a manual / transmission clutch gear that meshes with an electric motor. A rear-stage transmission gear section that includes a front-stage transmission gear section that transmits rotational torque and a plurality of gears that mesh with the manual / transmission clutch gear to give different reduction ratios, and that transmits the rotational torque from the electric motor to the output shaft side. Disengagement of the manual transmission / transmission clutch gear and either the front transmission gear section or the rear transmission gear section and manual / transmission clutch gear by manual operation of the gear section along the central axis of the manual / transmission clutch gear, / Clutch gear switching means for selectively engaging the gear between the transmission clutch gear and the rear transmission gear portion.

この発明に係るバルブ装置は、上記アクチュエータと、アクチュエータの出力軸の動作に応じて開閉するバルブ本体とを備えるものである。   The valve device according to the present invention includes the actuator and a valve body that opens and closes according to the operation of the output shaft of the actuator.

この発明に係るダンパ装置は、上記アクチュエータと、アクチュエータの出力軸の動作に応じて開閉するダンパ本体とを備えるものである。   A damper device according to the present invention includes the actuator and a damper body that opens and closes according to the operation of the output shaft of the actuator.

この発明によれば、同軸に一体で回転する複数のギアから構成された手動／変速クラッチギアを中心軸に沿って移動操作することにより、前段側伝達ギア又は後段側伝達ギアと手動／変速クラッチギアとの噛み合わせを解除し、また手動／変速クラッチギアと後段側伝達ギアとの間での所望の減速比を与えるギアを噛み合わせるので、同軸に一体で回転する簡易な構成のギアの追加により、ケーシング内の収納空間を占有する部品点数の増加を招くことなく、手動と電動の操作切り替え及び出力軸の変速を実現することができるという効果がある。また、上記アクチュエータをバルブ装置やダンパ装置に用いることで、手動でバルブやダンパの開度調整を行うことができる上、所望の速度でバルブを開閉制御できる。さらに、複数の動作速度が得られるので、バルブやダンパ等の駆動対象物の様々な動作制御仕様に対して１機種で対応することができる。   According to the present invention, the manual transmission / transmission clutch gear or the rear transmission gear and the manual / transmission clutch are operated by moving the manual / transmission clutch gear composed of a plurality of gears that rotate coaxially and integrally along the central axis. A gear with a simple structure that rotates together coaxially is added to release the meshing with the gear and mesh with the gear that gives the desired reduction ratio between the manual / transmission clutch gear and the rear transmission gear. Thus, there is an effect that switching between manual and electric operation and shifting of the output shaft can be realized without increasing the number of parts occupying the storage space in the casing. Further, by using the actuator in a valve device or a damper device, it is possible to manually adjust the opening degree of the valve or the damper and to control the opening / closing of the valve at a desired speed. Further, since a plurality of operation speeds can be obtained, it is possible to cope with various operation control specifications of a driving object such as a valve and a damper with one model.

実施の形態１．
図１は、この発明の実施の形態１によるアクチュエータの内部機構を概略的に示す図であり、図２は、図１中のギアユニットを示す図である。実施の形態１によるアクチュエータ１では、ケーシング内に収納された支持プレート２ａ，２ｂ、支持プレート２ａ上に配置された電動モータ３、支持プレート２ａ，２ｂを貫通して回転自在に設けられた出力軸４、及び電動モータ３の回転トルクを出力軸４まで伝達するギアユニットを備える。 Embodiment 1 FIG.

In the electric motor 3, the rotation shaft 5 is disposed through the support plate 2 a, and the transmission gear 6 is attached to the rotation shaft 5. The output shaft 4 of the actuator 1 is connected to a valve shaft of a valve (not shown) attached below in FIG. 1, and the valve opens and closes according to the rotation of the output shaft 4.

ギアユニットは、電動モータ３の回転軸５に取り付けられた伝達ギア６、伝達ギア６と噛み合う伝達ギア７ａ、伝達ギア７ａと同軸に一体に形成された伝達ギア７ｂ、ギア部８ａ，８ｂ，８ｃを有する手動／変速クラッチギア８、同軸に形成されて一体に回転する伝達ギア１０ａ，１０ｂ，１０ｃ、出力軸４と一体に回転する伝達ギア１２を備える。なお、同軸に一体に形成された伝達ギア７ａ，７ｂが前段側伝達ギアを構成し、同軸に形成されて一体に回転する伝達ギア１０ａ，１０ｂ，１０ｃが後段側伝達ギア部を構成する。   The gear unit includes a transmission gear 6 attached to the rotating shaft 5 of the electric motor 3, a transmission gear 7a meshing with the transmission gear 6, a transmission gear 7b formed integrally with the transmission gear 7a, and gear portions 8a, 8b, 8c. A manual / transmission clutch gear 8 having transmission gears 10a, 10b, 10c formed coaxially and rotating integrally therewith, and a transmission gear 12 rotating integrally with the output shaft 4. The transmission gears 7a and 7b that are integrally formed coaxially constitute a front-stage transmission gear, and the transmission gears 10a, 10b, and 10c that are coaxially formed and rotate integrally constitute a rear-stage transmission gear portion.

It is slidably attached along the axial direction indicated by.

It meshes with the small-diameter transmission gear 7b at the same pitch adjacent to the 3 side (hereinafter referred to as the front side).

なお、伝達ギア７ｂは、手動／変速クラッチギア８が固定軸９に沿ってスライドしても噛み合いが外れない歯幅を有している。つまり、図１及び図２では、手動／変速クラッチギア８により手動操作に切り替えた際、手動／変速クラッチギア８の前段側の伝達ギアとの噛み合いが維持され、後段側の伝達ギアとの噛み合いが外れる構成を示している。   The transmission gear 7b has a tooth width that does not disengage even when the manual / transmission clutch gear 8 slides along the fixed shaft 9. That is, in FIGS. 1 and 2, when the manual / transmission clutch gear 8 is switched to manual operation, the meshing with the transmission gear on the front stage side of the manual / transmission clutch gear 8 is maintained, and the meshing with the transmission gear on the rear stage side is maintained. Shows a configuration in which is removed.

手動／変速クラッチギア８のギア部８ａ（第１ギア部）は、ギア部８ｃより大径であり、手動／変速クラッチギア８の固定軸９に沿ったスライド操作により、出力軸４側（以降、後段側と称す）に隣接する伝達ギア１０ａ（第１ギア）との噛み合い及びその解除が選択的に決定される。また、ギア部８ｃ（第２ギア部）は、手動／変速クラッチギア８の固定軸９に沿ったスライド操作により、後段側に隣接する伝達ギア１０ｂ（第２ギア）との噛み合い及びその解除が選択的に決定される。   The gear portion 8a (first gear portion) of the manual / transmission clutch gear 8 has a larger diameter than the gear portion 8c, and the output shaft 4 side (hereinafter, referred to as “sliding operation” along the fixed shaft 9 of the manual / transmission clutch gear 8). Meshing with the transmission gear 10a (first gear) adjacent to the rear side) is selectively determined. The gear portion 8c (second gear portion) is engaged with and released from the transmission gear 10b (second gear) adjacent to the rear stage side by a slide operation along the fixed shaft 9 of the manual / transmission clutch gear 8. It is determined selectively.

本実施の形態１によるアクチュエータ１では、手動／変速クラッチギア８のギア部８ａと後段側の伝達ギア１０ａとが噛み合った状態と、手動／変速クラッチギア８のギア部８ｃと後段側の伝達ギア１０ｂとが噛み合った状態とが、それぞれ異なる減速比のギアユニットを構成する。   In the actuator 1 according to the first embodiment, the gear portion 8a of the manual / transmission clutch gear 8 and the rear transmission gear 10a mesh with each other, and the gear portion 8c of the manual / transmission clutch gear 8 and the rear transmission gear. 10b and the state which meshed | engaged respectively comprise the gear unit of a different reduction ratio.

手動／変速クラッチギア８の後段側に隣接して配置される伝達ギア１０ａ，１０ｂ，１０ｃは同軸に一体で回転するように形成されており、支持プレート２ａ，２ｂ間に軸支された回転軸１０に一体に取り付けられる。伝達ギア１０ｂは、伝達ギア１０ａ，１０ｃの双方よりも大径であり、伝達ギア１０ａは伝達ギア１０ｃよりも大径である。   The transmission gears 10a, 10b, 10c disposed adjacent to the rear side of the manual / transmission clutch gear 8 are formed so as to rotate coaxially and integrally, and are rotary shafts supported between the support plates 2a, 2b. 10 is attached integrally. The transmission gear 10b has a larger diameter than both the transmission gears 10a and 10c, and the transmission gear 10a has a larger diameter than the transmission gear 10c.

また、本実施の形態１では、手動／変速クラッチギア８の手動操作位置、つまり図１及び図２に示す伝達ギア１０ａとギア部８ａ及び伝達ギア１０ｂとギア部８ｃの噛み合いがそれぞれ解除される手動／変速クラッチギア８のスライド位置を基準として、後段側に隣接する伝達ギアを配置する。例えば、変速用のギア部８ａと噛み合わせる伝達ギア１０ａは、上記手動操作位置より支持プレート２ａ側に配置し、変速用のギア部８ｃと噛み合わせる伝達ギア１０ｂは上記手動操作位置より支持プレート２ｂ側に配置する。   In the first embodiment, the manual operation position of the manual / transmission clutch gear 8, that is, the meshing of the transmission gear 10a and the gear portion 8a and the transmission gear 10b and the gear portion 8c shown in FIGS. The transmission gear adjacent to the rear stage is arranged on the basis of the slide position of the manual / transmission clutch gear 8. For example, the transmission gear 10a that meshes with the gear portion 8a for shifting is arranged on the support plate 2a side from the manual operation position, and the transmission gear 10b that meshes with the gear portion 8c for shifting is supported by the support plate 2b from the manual operation position. Place on the side.

出力軸４と一体に回転する伝達ギア１２は、前段側に隣接する小径の伝達ギア１０ｃと噛み合う。伝達ギア１０ｃに伝わった電動モータ３の回転トルクは、伝達ギア１２を介して出力軸４に伝わり、バルブの開閉動作が行われる。   The transmission gear 12 that rotates integrally with the output shaft 4 meshes with a small-diameter transmission gear 10c adjacent to the front stage side. The rotational torque of the electric motor 3 transmitted to the transmission gear 10c is transmitted to the output shaft 4 via the transmission gear 12, and the valve is opened and closed.

また、回転軸１０には、支持プレート２ａを貫通し、ケーシング外に突出する手動操作レバー１１が設けられる。手動操作時に、手動／変速クラッチギア８をスライド操作して後段側の伝達ギアと前段側の伝達ギアとの連結を遮断し、手動操作レバー１１を回転軸１０に対して円周方向に回動操作すると、この回転トルクが伝達ギア１０ｃ，１２を経て出力軸４に伝わり回転する。   Further, the rotary shaft 10 is provided with a manual operation lever 11 that passes through the support plate 2a and protrudes out of the casing. During manual operation, the manual / transmission clutch gear 8 is slid to disconnect the connection between the rear transmission gear and the front transmission gear, and the manual operation lever 11 is rotated in the circumferential direction with respect to the rotary shaft 10. When operated, this rotational torque is transmitted to the output shaft 4 through the transmission gears 10c and 12 and rotated.

このように、本発明では、電動と手動の操作切り替え用のクラッチ機構と変速用のクラッチ機構とを、同軸で一体に回転するギアとして共通化している。これにより、ケーシング内の水平方向の空間を過剰に占有することなく、電動と手動の操作の切り替え機能と２変速機能とを簡易な構成で実現でき、アクチュエータの小型化を図ることができる。   Thus, in the present invention, the clutch mechanism for switching between electric and manual operation and the clutch mechanism for shifting are shared as a gear that rotates coaxially and integrally. Thereby, without excessively occupying the space in the horizontal direction in the casing, the switching function between the electric operation and the manual operation and the two-shift function can be realized with a simple configuration, and the actuator can be downsized.

図３は、クラッチギア切替手段を示す図であり、図３（ａ）は手動／変速クラッチギア８の支持プレート２ａ側からみた上面を示し、図３（ｂ）はピニオン部１７の軸方向に垂直な側面を示している。また、図３（ａ）において、支持プレート２ａを透明にして、手動／変速クラッチギア８と弾性緩衝部の構成を視認しやすく示している。   FIG. 3 is a view showing the clutch gear switching means, FIG. 3 (a) shows the top surface of the manual / transmission clutch gear 8 as viewed from the support plate 2 a side, and FIG. 3 (b) shows the axial direction of the pinion portion 17. The vertical side is shown. Further, in FIG. 3A, the support plate 2a is made transparent so that the configurations of the manual / transmission clutch gear 8 and the elastic buffer portion are easily visible.

このクラッチギア切替手段は、図３（ｂ）に示すように、固定軸９に沿って上下方向から手動／変速クラッチギア８を挟み込んで保持する弾性保持部材１３と、外部からピニオン部１７の軸に対して円周方向に加えられた回転力を固定軸９の軸方向に弾性保持部材１３をスライドさせる力に変換して弾性保持部材１３に保持された手動／変速クラッチギア８を固定軸９に沿ってスライドさせる操作部１６とを備える。   As shown in FIG. 3B, the clutch gear switching means includes an elastic holding member 13 that holds the manual / transmission clutch gear 8 in the vertical direction along the fixed shaft 9 and a shaft of the pinion portion 17 from the outside. The manual / transmission clutch gear 8 held by the elastic holding member 13 is converted by converting the rotational force applied in the circumferential direction into a force for sliding the elastic holding member 13 in the axial direction of the fixed shaft 9. And an operation unit 16 that is slid along the line.

弾性保持部材１３はその一端部で手動／変速クラッチギア８のギア部８ａの上面に当接して弾性保持する上方弾性保持部１３−１と、その一端部で手動／変速クラッチギア８のギア部８ｃの下面に当接して弾性保持する下方弾性保持部１３−２と、手動／変速クラッチギア８のギア部８ｂの外周に位置するとともに上方弾性保持部１３−１の他端部と下方弾性保持部１３−２の他端部とを連結する連結部１３−３から構成されており、その連結部１３−３の外側面には、操作部１６のピニオン部１７と噛み合うラック部（伝達部）１４が形成されており、ラック部１４の両側面部には、図３（ａ）、（ｂ）に示すように、固定軸９の軸方向に平行な溝部１５がそれぞれ形成されている。   The elastic holding member 13 has an upper elastic holding portion 13-1 which is elastically held in contact with the upper surface of the gear portion 8a of the manual / transmission clutch gear 8 at one end thereof, and a gear portion of the manual / transmission clutch gear 8 at one end thereof. A lower elastic holding portion 13-2 that is elastically held in contact with the lower surface of 8c, and is located on the outer periphery of the gear portion 8b of the manual / transmission clutch gear 8, and the other elastic end portion of the upper elastic holding portion 13-1 and the lower elastic holding portion A rack portion (transmission portion) that meshes with the pinion portion 17 of the operation portion 16 on the outer surface of the connection portion 13-3. 14 are formed, and groove portions 15 parallel to the axial direction of the fixed shaft 9 are respectively formed on both side surfaces of the rack portion 14 as shown in FIGS. 3 (a) and 3 (b).

また、図３（ａ）に示すように、ラック部１４の両溝部１５に対向するようにレール部１８が設けられる。レール部１８には、固定軸９に平行な線状の当接部１８ａが形成されており、当接部１８ａは溝部１５に係合する。なお、図３（ｂ）では、弾性保持部材１３及びその周辺構成を視認し易くするために、レール部１８の記載を省略している。   Moreover, as shown to Fig.3 (a), the rail part 18 is provided so that both the groove parts 15 of the rack part 14 may be opposed. The rail portion 18 is formed with a linear contact portion 18 a parallel to the fixed shaft 9, and the contact portion 18 a engages with the groove portion 15. In FIG. 3B, the rail portion 18 is not shown in order to make it easier to visually recognize the elastic holding member 13 and its peripheral configuration.

操作部１６は、ケーシングの外壁２ｃから突出して外部から回転操作が可能な操作ダイヤル２０と、この操作ダイヤル２０に一端が接続する操作軸１９と、操作軸１９の他端が接続し、ラック部１４に噛み合うピニオン部１７とを備える。操作ダイヤル２０により操作軸１９を中心軸とするピニオン部１７の回転操作が行われると、その回転がラック部１４に伝わり、固定軸９の軸方向に平行な移動に変換されて溝部１５を介し弾性保持部材１３がレール部１８の当接部１８ａ上を摺動する。これにより、手動／変速クラッチギア８は、弾性保持部材１３により上下から付勢力が加えられながら、固定軸９に沿ってスライドする。   The operation unit 16 protrudes from the outer wall 2c of the casing and can be rotated from outside, an operation shaft 19 having one end connected to the operation dial 20, and the other end of the operation shaft 19 connected to the rack unit. 14 and a pinion portion 17 that meshes with 14. When the rotation operation of the pinion part 17 with the operation shaft 19 as the central axis is performed by the operation dial 20, the rotation is transmitted to the rack part 14, and is converted into a movement parallel to the axial direction of the fixed shaft 9. The elastic holding member 13 slides on the contact portion 18 a of the rail portion 18. As a result, the manual / transmission clutch gear 8 slides along the fixed shaft 9 while an urging force is applied from above and below by the elastic holding member 13.

例えば、図３（ａ）に示す「ＭＡＮＵＡＬ」の位置に操作ダイヤル２０を回転させると、手動／変速クラッチギア８が、図１及び図２に示す後段側に隣接する伝達ギアとの噛み合いが解除される位置（手動操作位置）になる。また、一例ではあるが、「３０Ｓ」又は「６０Ｓ」はフルストローク動作時間（全閉から全開、もしくは全開から全閉までの動作時間）を示しており、３０秒又は６０秒でバルブの開度が変更されることを示している。つまり、「３０Ｓ」又は「６０Ｓ」の位置に操作ダイヤル２０を合わせると、手動／変速クラッチギア８のギア部８ａ又はギア部８ｃと後段側の伝達ギア１０ａ又は伝達ギア１０ｂとが噛み合う。   For example, when the operation dial 20 is rotated to the “MANUAL” position shown in FIG. 3A, the manual / transmission clutch gear 8 is disengaged from the transmission gear adjacent to the rear stage shown in FIGS. Position (manual operation position). In addition, as an example, “30S” or “60S” indicates a full stroke operation time (operation time from fully closed to fully open, or from fully open to fully closed), and the valve opening in 30 seconds or 60 seconds. Indicates that it will be changed. That is, when the operation dial 20 is set to the position “30S” or “60S”, the gear portion 8a or the gear portion 8c of the manual / transmission clutch gear 8 and the transmission gear 10a or the transmission gear 10b on the rear stage side mesh with each other.

上述したような手動／変速クラッチギア８のスライド操作により後段側のギアと手動／変速クラッチギア８のギア部とを噛み合わせる際に、後段側のギアと手動／変速クラッチギア８のギア部とが噛み合い位置にない場合がある。
即ち、本実施の形態１では、後段の伝達ギアと手動／変速クラッチギア８のギア部が噛み合いの位置にない場合、操作ダイヤル２０で設定された位置までラック部１４を固定軸９に沿ってスライドさせる力（手動／変速クラッチギア８のスライド方向の力）により、後段側の伝達ギアの歯端面と手動／変速クラッチギア８のギア部の歯端面とが上下に当接した状態になる。 When the rear gear and the gear portion of the manual / transmission clutch gear 8 are engaged by the sliding operation of the manual / transmission clutch gear 8 as described above, the rear gear and the gear portion of the manual / transmission clutch gear 8 are May not be in the meshing position.
That is, in the first embodiment, when the rear transmission gear and the manual / transmission clutch gear 8 are not in meshing positions, the rack portion 14 is moved along the fixed shaft 9 to the position set by the operation dial 20. Due to the sliding force (force in the sliding direction of the manual / transmission clutch gear 8), the tooth end surface of the rear transmission gear and the tooth end surface of the gear portion of the manual / transmission clutch gear 8 are brought into contact with each other in the vertical direction.

例えば、後段側の伝達ギア１０ａと手動／変速クラッチギア８のギア部８ａとを噛み合わせる際、本来であれば図４中で符号ｂを付した位置で両ギアが噛み合うが、両ギアが噛み合いの位置にない場合、図４中で符号ａを付した位置にギア部８ａがある状態で伝達ギア１０ａとギア部８ａとの双方の歯端面が上下に当接する。このとき、弾性保持部材１３の上方弾性保持部１３−１の保持力が弱まるとともに、弾性保持部材１３の下方弾性保持部１３−２による保持力は強まるものの、下方弾性保持部１３−２が図４に示す下向きの矢印で示す方向（スライド方向と逆方向）に弾性変形することによりその保持力の上昇も緩和される。それによって、両ギアの双方の歯端面の当接部に生じる応力が緩和され歯車の歯形の損傷を防ぐことができる。   For example, when the transmission gear 10a on the rear stage side and the gear portion 8a of the manual / transmission clutch gear 8 are meshed with each other, both gears mesh with each other at the position indicated by the symbol b in FIG. In the state where the gear portion 8a is not located, the tooth end surfaces of both the transmission gear 10a and the gear portion 8a abut on each other in a state where the gear portion 8a is located at the position indicated by a in FIG. At this time, the holding force of the upper elastic holding portion 13-1 of the elastic holding member 13 is weakened, and the holding force by the lower elastic holding portion 13-2 of the elastic holding member 13 is increased, but the lower elastic holding portion 13-2 is illustrated in FIG. The elastic force is deformed in the direction indicated by the downward arrow 4 shown in FIG. As a result, the stress generated at the contact portions of both tooth end surfaces of both gears is relieved and damage to the tooth profile of the gear can be prevented.

この後、電動モータ３を駆動させると、手動／変速クラッチギア８は固定軸９に対して回転して、噛み合い位置になかった両ギアが噛み合いの位置に移行すると、弾性保持部材１３はもとの状態に復帰し、復帰により発生した反力を上記スライド方向の力として開放する。そして、弾性保持部材１３は開放されたスライド方向の力によって、手動／変速クラッチギア８を固定軸９に沿って更に上方にスライドさせ、ギア部８ａは図４のｂの位置まで移動して伝達ギア１０ａと完全に噛み合うようになる。   Thereafter, when the electric motor 3 is driven, the manual / transmission clutch gear 8 rotates with respect to the fixed shaft 9, and when both gears that are not in the meshing position shift to the meshing position, the elastic holding member 13 is originally moved. The reaction force generated by the return is released as the force in the sliding direction. The elastic holding member 13 slides the manual / transmission clutch gear 8 further upward along the fixed shaft 9 by the released sliding force, and the gear portion 8a moves to the position b in FIG. The gear 10a is completely engaged.

一方、後段側の伝達ギア１０ｂと手動／変速クラッチギア８のギア部８ｃとを噛み合わせる際、本来であれば図４中で符号ｄを付した位置で両ギアが噛み合うが、両ギアが噛み合い位置にないと、図４中で符号ｃを付した位置にギア部８ｃがある状態で伝達ギア１０ｂとギア部８ｃとの双方の歯端面が上下に当接する。このとき、弾性保持部材１３の下方弾性保持部１３−２の保持力が弱まるとともに、弾性保持部材１３の上方弾性保持部１３−１の保持力は強まるものの、上方弾性保持部１３−１が図４に示す上向きの矢印で示す方向（スライド方向と逆方向）に弾性変形することによりその保持力の上昇も緩和される。それによって、両ギアの双方の歯端面の当接部に生じる応力が緩和され歯車の歯形の損傷を防ぐことができる。   On the other hand, when the transmission gear 10b on the rear stage side and the gear portion 8c of the manual / transmission clutch gear 8 are meshed with each other, both gears mesh with each other at the position indicated by the symbol d in FIG. If not, the tooth end surfaces of both the transmission gear 10b and the gear portion 8c abut on each other in a state where the gear portion 8c is located at the position denoted by c in FIG. At this time, while the holding force of the lower elastic holding portion 13-2 of the elastic holding member 13 is weakened and the holding force of the upper elastic holding portion 13-1 of the elastic holding member 13 is increased, the upper elastic holding portion 13-1 is illustrated in FIG. The elastic force is deformed in the direction indicated by the upward arrow shown in FIG. As a result, the stress generated at the contact portions of both tooth end surfaces of both gears is relieved and damage to the tooth profile of the gear can be prevented.

この後、電動モータ３を駆動させると、手動／変速クラッチギア８は固定軸９に対して回転して、噛み合い位置になかった両ギアが噛み合いの位置に移行すると、弾性保持部材１３はもとの状態に復帰し、復帰により発生した反力を上記スライド方向の力として開放する。そして、弾性保持部材１３は開放されたスライド方向の力によって、手動／変速クラッチギア８を固定軸９に沿って更に下方にスライドさせ、ギア部８ｃは図４のｄの位置まで移動して伝達ギア１０ｂと完全に噛み合うようになる。   Thereafter, when the electric motor 3 is driven, the manual / transmission clutch gear 8 rotates with respect to the fixed shaft 9, and when both gears that are not in the meshing position shift to the meshing position, the elastic holding member 13 is originally moved. The reaction force generated by the return is released as the force in the sliding direction. Then, the elastic holding member 13 slides the manual / transmission clutch gear 8 further downward along the fixed shaft 9 by the released sliding force, and the gear portion 8c moves to the position d in FIG. The gear 10b is completely engaged.

このように、図３に示すクラッチギア切替手段では、噛み合わせようとする両ギアが噛み合いの位置になく双方の歯端面が上下に当接しても、弾性保持部材１３の上方弾性保持部１３−１又は下方弾性保持部１３−２がスライド方向と逆方向に弾性変形することにより両ギアの双方の歯端面の当接部に生じる応力が緩和され歯車の歯形の損傷を防ぐことができ、その状態で電動モータ３を駆動することにより両ギアが噛み合い位置に移行すると、弾性保持部材１３はもとの状態に復帰することにより発生する反力により、両ギアを自動的に完全に噛み合い状態とすることができる。   In this way, in the clutch gear switching means shown in FIG. 3, even if the gears to be engaged are not in the meshing position and both tooth end surfaces abut vertically, the upper elastic retaining portion 13-of the elastic retaining member 13. 1 or the lower elastic holding portion 13-2 is elastically deformed in the direction opposite to the sliding direction, so that the stress generated in the contact portions of the tooth end surfaces of both gears can be relieved and the gear tooth profile can be prevented from being damaged. When both the gears are shifted to the meshing position by driving the electric motor 3 in the state, the elastic holding member 13 is automatically brought into the completely meshed state by the reaction force generated by returning to the original state. can do.

なお、手動／変速クラッチギア８のギア部（８ａ，８ｂ）と後段側の伝達ギア（１０ａ，１０ｂ）が噛み合い状態になると、弾性保持部材１３は変形状態からもとの状態に復帰し、上方弾性保持部１３−１の保持力と下方弾性保持部１３−２の保持力ももとに戻るので、手動／変速クラッチギア８は安定して保持される。   Note that when the gear portions (8a, 8b) of the manual / transmission clutch gear 8 and the transmission gears (10a, 10b) on the rear stage side are engaged with each other, the elastic holding member 13 returns from the deformed state to the original state, and Since the holding force of the elastic holding portion 13-1 and the holding force of the lower elastic holding portion 13-2 also return to the original, the manual / transmission clutch gear 8 is stably held.

図５は、クラッチギア切替手段の他の構成例を示す図であり、図５（ａ）はピニオン部１７の軸方向に垂直な側面を示し、図５（ｂ）は（ａ）中の矢印Ａ，Ｂの方向からそれぞれみたピニオン部１７及び弾性操作軸１９ａ，１９ｂを示している。図５に示す弾性緩衝部は、保持部材１３Ａと、操作部１６Ａ（又は操作部１６Ｂ）とを備える。保持部材１３Ａは、固定軸９に沿った上下から手動／変速クラッチギア８を挟み込むように保持する。図３に示した弾性保持部材１３と異なり、保持部材１３Ａ自体は弾性変形しない。   FIG. 5 is a diagram showing another example of the configuration of the clutch gear switching means, FIG. 5 (a) shows a side surface perpendicular to the axial direction of the pinion portion 17, and FIG. 5 (b) is an arrow in FIG. The pinion part 17 and the elastic operation shafts 19a and 19b viewed from the directions of A and B are shown. The elastic buffer portion shown in FIG. 5 includes a holding member 13A and an operation portion 16A (or operation portion 16B). The holding member 13 </ b> A holds the manual / transmission clutch gear 8 from above and below along the fixed shaft 9. Unlike the elastic holding member 13 shown in FIG. 3, the holding member 13A itself is not elastically deformed.

また、保持部材１３Ａも、図３に示した弾性保持部材１３と同様に、その一端部で手動／変速クラッチギア８のギア部８ａの上面に当接して保持する上方保持部１３Ａ−１と、その一端部で手動／変速クラッチギア８のギア部８ｃの下面に当接して保持する下方保持部１３Ａ−２と、手動／変速クラッチギア８のギア部８ｂの外周に位置するとともに上方保持部１３Ａ−１の他端部と下方保持部１３Ａ−２の他端部とを連結する連結部１３Ａ−３から構成されており、その連結部１３Ａ−３の外側面に操作部１６Ａ（又は操作部１６Ｂ）のピニオン部１７と噛み合うラック部（伝達部）１４が形成される。なお、保持部材１３Ａに対して弾性保持部材１３と同様な溝部を形成し、保持部材１３Ａの溝部がレール部の当接部上を摺動することにより、手動／変速クラッチギア８が、固定軸９に沿ってスライドする構成としてもよい。   Similarly to the elastic holding member 13 shown in FIG. 3, the holding member 13 </ b> A also has an upper holding portion 13 </ b> A- 1 that is held in contact with the upper surface of the gear portion 8 a of the manual / transmission clutch gear 8 at one end thereof, A lower holding portion 13A-2 that holds and abuts the lower surface of the gear portion 8c of the manual / transmission clutch gear 8 at one end thereof, and an upper holding portion 13A that is positioned on the outer periphery of the gear portion 8b of the manual / transmission clutch gear 8. -1 is connected to the other end of the lower holding portion 13A-2, and the operation portion 16A (or the operation portion 16B is provided on the outer surface of the connection portion 13A-3. ) Of the rack portion (transmission portion) 14 is formed. A groove portion similar to the elastic holding member 13 is formed on the holding member 13A, and the groove portion of the holding member 13A slides on the contact portion of the rail portion, whereby the manual / transmission clutch gear 8 is fixed to the fixed shaft. It is good also as a structure which slides along 9.

操作部１６Ａは、図３（ａ）に示したような操作ダイヤルに一端が接続する線状の弾性部材からなる弾性操作軸１９ａと、弾性操作軸１９ａの他端が接続し、保持部材１３Ａのラック部１４に噛み合うピニオン部１７とを備える。一方、操作部１６Ｂでは、図５（ｂ）に示すように、固定軸９の軸方向に対して垂直方向に延びる線状の弾性部材からなる弾性操作軸１９ｂを２本平行して設けている。   The operation unit 16A has an elastic operation shaft 19a made of a linear elastic member connected at one end to an operation dial as shown in FIG. 3A and the other end of the elastic operation shaft 19a connected to each other. And a pinion portion 17 that meshes with the rack portion 14. On the other hand, in the operation portion 16B, as shown in FIG. 5B, two elastic operation shafts 19b made of linear elastic members extending in a direction perpendicular to the axial direction of the fixed shaft 9 are provided in parallel. .

不図示の操作ダイヤルで弾性操作軸１９ａ（又は弾性操作軸１９ｂ，１９ｂ）を軸とするピニオン部１７の回転操作が行われると、その回転がラック部１４に伝わり、手動／変速クラッチギア８の固定軸９の軸方向に沿った移動に変換されて手動／変速クラッチギア８がスライドする。   When the pinion portion 17 is rotated about the elastic operation shaft 19a (or the elastic operation shafts 19b and 19b) by an operation dial (not shown), the rotation is transmitted to the rack portion 14, and the manual / transmission clutch gear 8 The manual / transmission clutch gear 8 is slid by being converted into movement along the axial direction of the fixed shaft 9.

ここで、後段側の伝達ギアと手動／変速クラッチギア８のギア部とが噛み合い位置にない場合、操作ダイヤルで設定された位置までラック部１４を固定軸９に沿ってスライドさせる力（手動／変速クラッチギア８のスライド方向の力）により、後段側の伝達ギアと手動／変速クラッチギア８のギア部の双方の歯端面が上下に当接した状態になる。   Here, when the transmission gear on the rear stage side and the gear portion of the manual / transmission clutch gear 8 are not in the meshing position, the force for sliding the rack portion 14 along the fixed shaft 9 to the position set by the operation dial (manual / Due to the sliding force of the transmission clutch gear 8, the tooth end surfaces of both the rear transmission gear and the gear portion of the manual / transmission clutch gear 8 are brought into contact with each other vertically.

上述のように歯端面が当接して手動／変速クラッチギア８のスライドが規制されると、操作ダイヤルの回転操作により加えられた回転力によって、弾性操作軸１９ａ（又は弾性操作軸１９ｂ，１９ｂ）が、図５（ｂ）に示すように捩れ変形する。
つまり、図５に示すクラッチギア切替手段では、両ギアが噛み合いの位置になるまで、手動／変速クラッチギア８を所定のスライド位置に設定するためのスライド方向の力が、弾性操作軸１９ａ（又は弾性操作軸１９ｂ，１９ｂ）の捩れ変形によって吸収（蓄積）される。このように構成することでも、図３に示したクラッチギア切替手段と同様に、当接する両ギアの歯端面にかかる応力を緩和し、歯車の歯形の損傷を防ぐことができる。 As described above, when the tooth end surfaces come into contact with each other and the sliding of the manual / transmission clutch gear 8 is restricted, the elastic operation shaft 19a (or the elastic operation shafts 19b and 19b) is caused by the rotational force applied by the rotation operation of the operation dial. However, it twists and deforms as shown in FIG.
That is, in the clutch gear switching means shown in FIG. 5, the force in the sliding direction for setting the manual / transmission clutch gear 8 to a predetermined sliding position until the both gears are in the meshing position is the elastic operation shaft 19a (or It is absorbed (accumulated) by torsional deformation of the elastic operating shafts 19b, 19b). Even with this configuration, similarly to the clutch gear switching unit shown in FIG. 3, stress applied to the tooth end surfaces of both gears in contact can be relieved, and damage to the tooth profile of the gear can be prevented.

この後、電動モータ３を駆動させる等して両ギアを噛み合い位置にすると、弾性操作軸１９ａ（又は弾性操作軸１９ｂ，１９ｂ）は、捩れ変形状態から捻れのない状態に復帰し、復帰の際に発生する反力を上記スライド方向の力として解放する。この力はピニオン部１７からラック部１４に伝達されることにより、手動／変速クラッチギア８が、保持部材１３Ａを介して操作ダイヤルで設定された適切な位置にスライドして後段側の伝達ギアと噛み合う。   Thereafter, when both the gears are brought into the meshing position by driving the electric motor 3 or the like, the elastic operation shaft 19a (or the elastic operation shafts 19b and 19b) returns from the torsionally deformed state to the non-twisted state. The reaction force generated in is released as the force in the sliding direction. This force is transmitted from the pinion portion 17 to the rack portion 14 so that the manual / transmission clutch gear 8 slides to an appropriate position set by the operation dial via the holding member 13A and the transmission gear on the rear stage side. Engage.

なお、図３乃至図５に示した構成の他、手動／変速クラッチギア８の上下に巻バネ部材を設け、これら巻バネ部材によって手動／変速クラッチギア８に対して上下双方から付勢力を与えるようにしても良いし、要は手動／変速クラッチギア８の上下双方に弾性保持力を与えられる構成を付加することができればどのような構成でも良い。これらの構成によっても、上記と同様な効果を得ることができる。   In addition to the configuration shown in FIGS. 3 to 5, winding spring members are provided above and below the manual / transmission clutch gear 8, and an urging force is applied to the manual / transmission clutch gear 8 from both above and below by these winding spring members. In other words, any configuration may be used as long as it can add a configuration capable of applying an elastic holding force to both the upper and lower sides of the manual / transmission clutch gear 8. Even with these configurations, the same effect as described above can be obtained.

以上のように、この実施の形態１によれば、電動モータ３からの回転トルクを伝える前段側の伝達ギアと噛み合うギア部と、変速用の径の異なる複数のギア部とが同軸に形成され、固定軸９を中心として全てのギア部が一体に回転すると共に、固定軸９に沿ってスライド可能な手動／変速クラッチギア８を備え、手動／変速クラッチギア８のギア部と後段側の伝達ギアとの連結が外れる手動操作時の状態と、変速用の径の異なる複数のギア部の各々と後段側の対応する伝達ギアとが噛み合う各変速の状態とを、固定軸９に沿った手動／変速クラッチギア８のスライド操作により選択的に決定する。このように構成することで、ケーシング内の収納空間を占有する部品点数の増加を招くことなく、同軸にギアを組み合わせた簡易な構成の手動／変速クラッチギア８を追加するだけで、手動と電動の操作切り替えと変速の双方を実現することができる。   As described above, according to the first embodiment, the gear portion that meshes with the transmission gear on the front stage that transmits the rotational torque from the electric motor 3 and the plurality of gear portions with different diameters for shifting are formed coaxially. In addition, all the gear portions rotate integrally around the fixed shaft 9 and are provided with a manual / transmission clutch gear 8 that can slide along the fixed shaft 9, and transmission between the gear portion of the manual / transmission clutch gear 8 and the rear stage side. The manual operation along the fixed shaft 9 includes a manual operation state in which the gear is disconnected and a shift state in which each of the plurality of gear portions having different diameters for transmission and the corresponding transmission gear on the rear stage side mesh with each other. / Selectively determined by sliding operation of the transmission clutch gear 8. By configuring in this way, the manual / transmission clutch gear 8 having a simple configuration in which gears are coaxially combined is added without causing an increase in the number of parts occupying the storage space in the casing. Both operation switching and shifting can be realized.

また、上記実施の形態１によれば、手動／変速クラッチギア８と後段側の伝達ギアとが噛み合い位置になく、両ギアの歯端面が上下に当接した際、弾性保持部材１３や弾性操作軸１９ａ，１９ｂの弾性変形により手動／変速クラッチギア８のスライド方向の力を吸収して両ギアの歯端面への応力を緩和することができる。さらに、両ギアが噛み合い位置になると、弾性変形した弾性保持部材１３や弾性操作軸１９ａ，１９ｂがもとの状態に復帰して、その反力を手動／変速クラッチギア８の固定軸９に沿ったスライド方向の力として解放する。この力によって両ギアを適切な位置で噛み合わせることができる。   Further, according to the first embodiment, when the manual / transmission clutch gear 8 and the transmission gear on the rear stage side are not in the meshing position and the tooth end surfaces of both gears are in contact with each other in the vertical direction, the elastic holding member 13 or the elastic operation is performed. The elastic deformation of the shafts 19a and 19b can absorb the force in the sliding direction of the manual / transmission clutch gear 8 to relieve the stress on the tooth end surfaces of both gears. Further, when both gears are brought into the meshing position, the elastically deformed elastic holding member 13 and the elastic operation shafts 19a and 19b are restored to their original states, and the reaction force is transferred along the fixed shaft 9 of the manual / transmission clutch gear 8. Release as a force in the sliding direction. With this force, both gears can be engaged at an appropriate position.

さらに、上記実施の形態１では、手動／変速クラッチギア８がギア部８ａ，８ｃによる２変速である場合を示したが、本発明は２変速に限定されるものではない。
図６は、実施の形態１によるギアユニットの他の構成例を示す図である。ギア部２１ａ，２１ｂ，２１ｃは、上記実施の形態１で示した手動／変速クラッチギア８のギア部８ａ，８ｂ，８ｃに相当するものであるが、図６に示す手動／変速クラッチギア２１には、ギア部２１ｃより小径のギア部２１ｄをさらに設けている。また、後段側に隣接する伝達ギアとして、ギア部２１ｄに対応する伝達ギア１０ｄを、伝達ギア１０ａ，１０ｂ，１０ｃと同軸で一体に回転するように設けている。 Furthermore, in the first embodiment, the case where the manual / transmission clutch gear 8 is a two-speed change by the gear portions 8a and 8c is shown, but the present invention is not limited to the two-speed change.
FIG. 6 is a diagram illustrating another configuration example of the gear unit according to the first embodiment. The gear portions 21a, 21b, and 21c correspond to the gear portions 8a, 8b, and 8c of the manual / transmission clutch gear 8 shown in the first embodiment, but the manual / transmission clutch gear 21 shown in FIG. Is further provided with a gear portion 21d having a smaller diameter than the gear portion 21c. Further, as a transmission gear adjacent to the rear stage side, a transmission gear 10d corresponding to the gear portion 21d is provided so as to rotate integrally with the transmission gears 10a, 10b, and 10c.

このように、本発明では、ギア部２１ｄと伝達ギア１０ｄによる変速段を一段追加して３変速としたが、それ以上の変速段数にも容易に拡張可能である。   As described above, in the present invention, the gear portion by the gear portion 21d and the transmission gear 10d is added one step to obtain three shifts. However, the present invention can be easily extended to more shift steps.

実施の形態２．
上記実施の形態１では手動操作するにあたり、手動／変速クラッチギアによって後段側の伝達ギアとの連結を遮断する例を示したが、本実施の形態２は、手動／変速クラッチギアにより前段側の伝達ギアとの連結を遮断するものである。 Embodiment 2. FIG.
In the first embodiment, an example in which the manual / transmission clutch gear cuts off the connection with the transmission gear on the rear stage side in the manual operation has been shown. The connection with the transmission gear is cut off.

図７は、この発明の実施の形態２によるアクチュエータのギアユニットを示す図である。図７に示すギアユニットは、電動モータ３の回転軸５に固定された伝達ギア６、ギア部２２ａ，２２ｂ，２２ｃ，２２ｄを有する手動／変速クラッチギア２２、同軸に形成されて一体に回転する伝達ギア２４ａ，２４ｂ，２４ｃを備える。   FIG. 7 is a diagram showing a gear unit of an actuator according to Embodiment 2 of the present invention. The gear unit shown in FIG. 7 has a transmission gear 6 fixed to the rotating shaft 5 of the electric motor 3, a manual / transmission clutch gear 22 having gear portions 22a, 22b, 22c, and 22d, and is formed coaxially and rotates integrally. Transmission gears 24a, 24b, and 24c are provided.

手動／変速クラッチギア２２は、同軸に一体に形成されたギア部２２ａ，２２ｂ，２２ｃ，２２ｄから構成され、支持プレート２ａ，２ｂに固定された固定軸２３に回転自在で、かつ固定軸２３の軸方向に沿ってスライド可能に設けられる。なお、手動／変速クラッチギア２２の各ギア部では、支持プレート２ａ側から２ｂ側に向かって小径のギア部が形成され、電動操作時においてギア部２２ａと電動モータ３の回転軸５に取り付けられた伝達ギア６とが噛み合う。また、伝達ギア２４ａには図示しない出力軸と一体に回転する伝達ギア（図１中の伝達ギア１２に相当するもの）と常時噛み合っている。   The manual / transmission clutch gear 22 includes gear portions 22a, 22b, 22c, and 22d that are integrally formed on the same axis. The manual / transmission clutch gear 22 is rotatable on a fixed shaft 23 that is fixed to the support plates 2a and 2b. It is provided so as to be slidable along the axial direction. In each gear portion of the manual / transmission clutch gear 22, a small-diameter gear portion is formed from the support plate 2a side to the 2b side and is attached to the gear portion 22a and the rotating shaft 5 of the electric motor 3 during electric operation. The transmission gear 6 is engaged. Further, the transmission gear 24a always meshes with a transmission gear (corresponding to the transmission gear 12 in FIG. 1) that rotates integrally with an output shaft (not shown).

実施の形態２によるアクチュエータでは、ギア部２２ａと伝達ギア６との噛み合いが外れない範囲で手動／変速クラッチギア２２を固定軸２３に沿ってスライド操作することにより、ギア部（第１ギア部）２２ｄと後段側に隣接する伝達ギア（第１ギア）２４ｃとが噛み合う状態と、ギア部（第２ギア部）２２ｃと後段側に隣接する伝達ギア（第２ギア）２４ｂとが噛み合う状態と、ギア部（第３ギア部）２２ｂと後段側に隣接する伝達ギア（第３ギア）２４ａとが噛み合う状態の３段階の回転速度を選択することが可能である。   In the actuator according to Embodiment 2, the manual / transmission clutch gear 22 is slid along the fixed shaft 23 within a range in which the gear portion 22a and the transmission gear 6 are not disengaged, whereby the gear portion (first gear portion). 22d and the transmission gear (first gear) 24c adjacent to the rear stage side mesh with each other, and the gear portion (second gear part) 22c and the transmission gear (second gear) 24b adjacent to the rear stage side mesh with each other. It is possible to select three stages of rotation speeds in a state where the gear part (third gear part) 22b and the transmission gear (third gear) 24a adjacent to the rear stage side mesh with each other.

また、手動操作時には、手動／変速クラッチギア２２を固定軸２３に沿って更に下方にスライド操作してギア部２２ａと伝達ギア６との噛み合いを外せば良く、手動操作としては、例えば後段側伝達ギアの回転軸２４の支持プレートから外部に露出した端部２５の周面に取り付けられた手動操作レバー２６を回動操作することによって回転トルクを出力軸に伝え、出力軸を回転させる。   Further, at the time of manual operation, the manual / transmission clutch gear 22 may be slid further downward along the fixed shaft 23 to disengage the gear portion 22a from the transmission gear 6. A rotating torque is transmitted to the output shaft by rotating a manual operation lever 26 attached to the peripheral surface of the end 25 exposed to the outside from the support plate of the rotating shaft 24 of the gear, and the output shaft is rotated.

以上のように、この実施の形態２によれば、同軸にギアを組み合わせた簡易な構成の手動／変速クラッチギア２２を追加するだけで、手動操作と電動操作の切り替え機能と変速用機能の双方を実現することができる。   As described above, according to the second embodiment, both the manual operation and the electric operation switching function and the shifting function can be achieved by simply adding the manual / transmission clutch gear 22 having a simple configuration in which gears are coaxially combined. Can be realized.

なお、実施の形態１及び２では選択的に手動／変速クラッチギアのギア部と噛み合う変速用の減速比の異なる複数の伝達ギアを手動／変速クラッチギアの後段に配置した例を示したが、これらの伝達ギアを電動モータと手動／変速クラッチギアとの間、即ち、手動／変速クラッチギアの前段に配置しても良く、本発明の技術思想の範囲に含まれる。
また、これら選択的に手動／変速クラッチギアのギア部と噛み合う変速用の減速比の異なる複数の伝達ギアを同軸に一体に設けずに、それぞれ異なる軸を中心に回転するように構成し、電動時には手動／変速クラッチギアの位置の違いによって、それぞれ異なる伝達ギアを経由して出力軸に電動モータの回転トルクを伝達するように構成することも本発明の技術思想の範囲に含まれる。 In the first and second embodiments, an example is shown in which a plurality of transmission gears having different gear reduction ratios that are selectively meshed with the gear portion of the manual / transmission clutch gear are arranged at the subsequent stage of the manual / transmission clutch gear. These transmission gears may be arranged between the electric motor and the manual / transmission clutch gear, that is, before the manual / transmission clutch gear, and are included in the scope of the technical idea of the present invention.
In addition, a plurality of transmission gears with different speed reduction ratios that selectively mesh with the gear portions of the manual / transmission clutch gears are configured so as to rotate about different shafts without being coaxially integrated. It is also included in the scope of the technical idea of the present invention that the rotational torque of the electric motor is transmitted to the output shaft via different transmission gears depending on the position of the manual / transmission clutch gear.

本発明によるアクチュエータは、図８に示したようなバルブ装置に適用することで、より効果を発揮することができる。例えば、弁軸の回転により開度が決定されるボールバルブのバルブ開閉を電動制御するバルブ装置を構成するにあたり、本発明によるアクチュエータで弁軸の回転を制御する。   The actuator according to the present invention can be more effective when applied to the valve device as shown in FIG. For example, in configuring a valve device that electrically controls the opening and closing of a ball valve whose opening degree is determined by the rotation of the valve shaft, the rotation of the valve shaft is controlled by the actuator according to the present invention.

このバルブ装置では、上記実施の形態１、２で説明したように出力軸の回転速度を変速することができるので、所望の速度でバルブを開閉制御できる。また、手動／変速クラッチギアのスライド操作により容易に手動でバルブの開度調整を行うこともできる。
なお、上述のようなバルブ装置を構成するバルブとしては、ボールバルブに限定されるものでなく、本発明によるアクチュエータの出力軸の回転に応じて開閉するものであればよいし、また、弁軸を垂直方向に上昇下降させて弁開度を制御する直動型のバルブにも適用できる。 In this valve device, the rotational speed of the output shaft can be changed as described in the first and second embodiments, so that the valve can be controlled to open and close at a desired speed. Further, the valve opening degree can be easily adjusted manually by sliding the manual / transmission clutch gear.
The valve constituting the valve device as described above is not limited to a ball valve, and may be any valve that opens and closes according to the rotation of the output shaft of the actuator according to the present invention. It can also be applied to a direct acting type valve that controls the valve opening degree by raising and lowering the valve vertically.

更に、ダンパ開度の制御を行うダンパ装置にも適用でき、その場合も上記実施の形態１、２で説明したように出力軸の回転速度を変速することができるので、所望の速度でダンパを開閉制御できる。また、停電時でも手動／変速クラッチギアのスライド操作により容易に手動でダンパの開度調整を行うこともできる。   Furthermore, the present invention can also be applied to a damper device that controls the damper opening. In this case, the rotational speed of the output shaft can be changed as described in the first and second embodiments. Open / close control is possible. Further, even during a power failure, the damper opening can be easily adjusted manually by sliding the manual / transmission clutch gear.
