Description

本発明は、エレベータの速度を検出するエレベータ用速度検出器が備える弾性回転体に許容磨耗範囲を超える磨耗が生じているかどうかを判定する磨耗判定装置に関する。 The present invention relates to a wear determination device that determines whether or not wear exceeding an allowable wear range has occurred in an elastic rotor included in an elevator speed detector that detects the speed of an elevator.

エレベータの速度を検出するための速度検出器としては、従来様々なタイプのものが提案されており、その一つとして、巻上機のモータに直結されてモータの動力により回転する回転体（ロータ）に対して弾性回転体を当接し、この弾性回転体の回転をもとにエレベータの速度を検出するものが知られている（例えば、特許文献１参照）。この種の速度検出器は、既設の巻上機に対して後付けで容易に設置することができるという利点があり、エレベータに新たな機能を付加する場合などに多く用いられる。
特開２００６−１６０４１５号公報（図２、図３） Conventionally, various types of speed detectors for detecting the speed of an elevator have been proposed. One of them is a rotating body (rotor) that is directly connected to a motor of a hoisting machine and is rotated by the power of the motor. ), And an elevator speed is detected based on the rotation of the elastic rotator (see, for example, Patent Document 1). This type of speed detector has an advantage that it can be easily installed later on an existing hoisting machine, and is often used when a new function is added to an elevator.
Japanese Patent Laying-Open No. 2006-160415 (FIGS. 2 and 3)

ところで、以上のような構成のエレベータ用速度検出器は、弾性回転体をロータに押し付けてロータの回転と同期させて回転させる構成であるため、経年劣化によって弾性回転体に磨耗が生じる。そして、弾性回転体の磨耗が許容範囲を超えるほどに進行すると、エレベータの速度検出誤差が無視できないレベルになる。そのため、定期的なメンテナンス時等に弾性回転体の磨耗の度合いを判定して、弾性回転体の磨耗が許容範囲を超えていれば部品交換などの対応を図ることが求められるが、弾性回転体は温度上昇等により変形が生じるため、一般的なノギスによる計測などで弾性回転体の磨耗度合いを正確に判定することが困難であった。 By the way, the elevator speed detector configured as described above is configured to press the elastic rotating body against the rotor and rotate in synchronization with the rotation of the rotor, and therefore, the elastic rotating body is worn due to deterioration over time. When the abrasion of the elastic rotating body progresses beyond the allowable range, the elevator speed detection error becomes a level that cannot be ignored. Therefore, it is required to determine the degree of wear of the elastic rotating body during regular maintenance, etc., and to take measures such as replacing parts if the wear of the elastic rotating body exceeds the allowable range. Since deformation occurs due to a temperature rise or the like, it is difficult to accurately determine the degree of wear of the elastic rotating body by measurement using a general caliper.

本発明は、以上のような従来の実情に鑑みて創案されたものであって、エレベータ用速度検出器の弾性回転体に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる磨耗判定装置を提供することを目的としている。 The present invention was devised in view of the above-described conventional situation, and accurately and easily determines whether or not wear exceeding an allowable wear range has occurred in the elastic rotor of the elevator speed detector. An object of the present invention is to provide a wear determination device capable of performing the above.

本発明に係る磨耗判定装置は、板状部材に弾性回転体の許容磨耗範囲に対応した大きさの磨耗計測部を形成した判定治具を備える。そして、この判定治具をエレベータ用速度検出器の弾性回転体に突き合わせたときに弾性回転体が磨耗計測部に干渉するか否かによって弾性回転体の磨耗度合いが許容磨耗範囲を超えているか否かを判定する。 The wear determination apparatus according to the present invention includes a determination jig in which a wear measuring unit having a size corresponding to an allowable wear range of an elastic rotating body is formed on a plate-like member. Whether or not the degree of wear of the elastic rotating body exceeds the allowable wear range depending on whether or not the elastic rotating body interferes with the wear measuring unit when the determination jig is abutted against the elastic rotating body of the elevator speed detector. Determine whether.

本発明に係る磨耗判定装置によれば、磨耗計測部を形成した判定治具をエレベータ用速度検出器の弾性回転体に突き合わせるだけで、弾性回転体に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる。 According to the wear determination apparatus according to the present invention, is the wear that exceeds the allowable wear range occurring in the elastic rotor only by abutting the determination jig formed with the wear measuring unit against the elastic rotor of the elevator speed detector? Whether or not can be determined accurately and simply.

以下、本発明を実施するための最良の形態について、図面を参照しながら詳細に説明する。 Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

［第１の実施形態］
図１は、エレベータ巻上機の一例を示す模式図である。エレベータ巻上機１は、図示しない乗りかごを昇降路内で昇降させるための駆動力を発生するものであり、例えば、昇降路上部に設けられた機械室のマシンビーム２上に固定されて設置される。 [First Embodiment]
FIG. 1 is a schematic diagram illustrating an example of an elevator hoisting machine. The elevator hoisting machine 1 generates a driving force for raising and lowering a car (not shown) in a hoistway. For example, the elevator hoisting machine 1 is fixedly installed on a machine beam 2 in a machine room provided at an upper part of the hoistway. Is done.

この図１に示すエレベータ巻上機１は、トラクション式の巻上機であり、モータ３の回転軸３ａにメインシーブ４が取り付けられ、このメインシーブ４に、乗りかごを吊り下げるメインロープ５が架け渡された構造である。このエレベータ巻上機１は、モータ３の駆動によりメインシーブ４を回転させ、メインシーブ４とメインロープ５との間の摩擦力を利用してメインロープ５を送り動作することにより、メインロープ５により吊り下げられた乗りかごを昇降路内で昇降させる。なお、モータ３とメインシーブ４との間には、必要に応じてモータ３の駆動力を増幅する減速機が設けられる。 The elevator hoisting machine 1 shown in FIG. 1 is a traction type hoisting machine. A main sheave 4 is attached to a rotating shaft 3 a of a motor 3, and a main rope 5 for suspending a car is attached to the main sheave 4. It is a bridged structure. The elevator hoisting machine 1 rotates the main sheave 4 by driving the motor 3 and feeds the main rope 5 using the frictional force between the main sheave 4 and the main rope 5, whereby the main rope 5 The elevator car is lifted and lowered in the hoistway. A reduction gear that amplifies the driving force of the motor 3 is provided between the motor 3 and the main sheave 4 as necessary.

このエレベータ巻上機１において、モータ３の回転軸３ａには、メインシーブ４と一体となって回転するロータ６（回転体）が取り付けられている。また、エレベータ巻上機１には、ロータ６の回転を利用してエレベータの速度を検出するための速度検出器１０が設けられている。 In the elevator hoist 1, a rotor 6 (rotary body) that rotates integrally with a main sheave 4 is attached to a rotating shaft 3 a of a motor 3. Further, the elevator hoist 1 is provided with a speed detector 10 for detecting the speed of the elevator using the rotation of the rotor 6.

速度検出器１０は、図１及び図２に示すように、装置本体１１から突出する回転中心軸１２に弾性回転体１３を回転自在に装着し、この弾性回転体１３をロータ６の周面に当接させた構造である。装置本体１１としては、例えばパルスジェネレータもしくはレゾルバ等の既知の検出器が用いられる。また、弾性回転体１３は、ゴムなどの弾性部材が円環状に成形されてなるものであり、その中心に挿入された回転中心軸１２によって装置本体１１に軸支されている。この速度検出器１０では、ロータ６の回転に同期した弾性回転体１３の回転が回転中心軸１２を介して装置本体１１に伝達されることで、装置本体１１においてメインシーブ４により送り動作されるメインロープ５の送り速度、すなわちエレベータの速度が検出される。なお、図２は速度検出器１０の近傍を図１中の矢印Ａ方向に見た側面図である。 As shown in FIGS. 1 and 2, the speed detector 10 has an elastic rotator 13 rotatably mounted on a rotation center shaft 12 protruding from the apparatus main body 11, and the elastic rotator 13 is attached to the circumferential surface of the rotor 6. The structure is abutted. As the apparatus main body 11, a known detector such as a pulse generator or a resolver is used, for example. The elastic rotator 13 is formed by forming an elastic member such as rubber in an annular shape, and is pivotally supported on the apparatus main body 11 by a rotation center shaft 12 inserted in the center thereof. In the speed detector 10, the rotation of the elastic rotating body 13 synchronized with the rotation of the rotor 6 is transmitted to the apparatus main body 11 through the rotation center shaft 12, so that the main sheave 4 feeds the apparatus main body 11. The feed speed of the main rope 5, that is, the elevator speed is detected. 2 is a side view of the vicinity of the speed detector 10 as viewed in the direction of arrow A in FIG.

速度検出器１０は、以上のように、弾性回転体１３をロータ６の周面に当接してロータ６の回転と同期させて回転させる構成であるため、長期間の使用による経年劣化等によって弾性回転体１３に磨耗が生じる。そして、弾性回転体１３の磨耗が許容範囲を超えるほどに進行すると、エレベータの速度検出誤差が無視できないレベルになる。そのため、定期的なメンテナンス時等において弾性回転体１３の磨耗の度合いを判定し、弾性回転体１３の磨耗が許容範囲を超えていれば部品交換などの対応を図ることが求められる。本発明に係る磨耗判定装置は、この速度検出器１０の弾性回転体１３の磨耗度合いを正確且つ簡便に判定するためのものであり、板状部材に弾性回転体１３の許容磨耗範囲に対応した大きさの磨耗計測部を形成した判定治具を用い、この判定治具を弾性回転体１３に突き合わせたときに弾性回転体１３が磨耗計測部に干渉するか否かによって弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定するものである。なお、図１及び図２に示す速度検出器１０は、弾性回転体１３をロータ６の周面に当接する構成であるが、弾性回転体１３をロータ６の側面に当接する構成の速度検出器も存在し、本発明に係る磨耗判定装置は、このような構成の速度検出器に対しても有効に適用可能である。 As described above, the speed detector 10 is configured to rotate the elastic rotating body 13 in contact with the circumferential surface of the rotor 6 in synchronization with the rotation of the rotor 6. Wear occurs in the rotating body 13. When the abrasion of the elastic rotating body 13 proceeds to exceed the allowable range, the elevator speed detection error becomes a level that cannot be ignored. For this reason, it is required to determine the degree of wear of the elastic rotator 13 during regular maintenance or the like, and to take measures such as component replacement if the wear of the elastic rotator 13 exceeds an allowable range. The wear determination device according to the present invention is for accurately and simply determining the degree of wear of the elastic rotating body 13 of the speed detector 10 and corresponds to the allowable wear range of the elastic rotating body 13 on the plate-like member. Using a determination jig formed with a wear measuring unit having a size, the wear of the elastic rotating body 13 depends on whether the elastic rotating body 13 interferes with the wear measuring unit when the determination jig is abutted against the elastic rotating body 13. It is determined whether or not the degree exceeds the allowable wear range. The speed detector 10 shown in FIGS. 1 and 2 has a configuration in which the elastic rotor 13 is in contact with the circumferential surface of the rotor 6, but a speed detector in a configuration in which the elastic rotor 13 is in contact with the side surface of the rotor 6. The wear determination device according to the present invention can be effectively applied to the speed detector having such a configuration.

図３は、本発明の第１の実施形態を説明する図であり、磨耗判定装置に用いる判定治具の一例を示す斜視図である。本実施形態の磨耗判定装置では、図３に示すように、板状部材２１の厚み方向に凹設された円形の凹部２２を上記の磨耗計測部とした判定治具２０を用いる。すなわち、本実施形態の磨耗判定装置で用いる判定治具２０は、例えば金属や合成樹脂などの所定の剛性を有する部材が矩形板状に成形されてなる板状部材２１を母材とし、この板状部材２１の一主面上に、弾性回転体１３の許容磨耗範囲に対応した大きさ（許容磨耗範囲の最大限まで磨耗が進行した弾性回転体１３と略同じ大きさ）の円形凹部２２が、板状部材２１の厚み方向に沿って凹設されている。また、円形凹部２２の中心位置には、弾性回転体１３の回転中心軸１２と略同径の軸挿通孔２３が、板状部材２１の厚み方向に貫通するように形成されている。なお、円形凹部２２の周壁の一部は、板状部材２１の一端面２１ａにて開放されている。 FIG. 3 is a diagram illustrating the first embodiment of the present invention, and is a perspective view illustrating an example of a determination jig used in the wear determination device. In the wear determination apparatus of the present embodiment, as shown in FIG. 3, a determination jig 20 is used in which a circular recess 22 provided in the thickness direction of the plate-like member 21 is used as the wear measurement unit. That is, the determination jig 20 used in the wear determination apparatus of the present embodiment uses, as a base material, a plate-like member 21 formed by forming a member having a predetermined rigidity such as metal or synthetic resin into a rectangular plate shape. A circular recess 22 having a size corresponding to the allowable wear range of the elastic rotator 13 (substantially the same size as the elastic rotator 13 in which wear has progressed to the maximum allowable wear range) is formed on one main surface of the cylindrical member 21. The plate-like member 21 is recessed along the thickness direction. A shaft insertion hole 23 having substantially the same diameter as the rotation center shaft 12 of the elastic rotator 13 is formed at the center position of the circular recess 22 so as to penetrate in the thickness direction of the plate member 21. A part of the peripheral wall of the circular recess 22 is opened at one end surface 21 a of the plate-like member 21.

本実施形態の磨耗判定装置により速度検出器１０の弾性回転体１３の磨耗度合いを判定する場合、まず、以上の構成とされた判定治具２０を速度検出器１０側に近づけて、弾性回転体１３に突き合わせる。このとき、円形凹部２２の一部が開放されている板状部材２１の一端面２１ａを、ロータ６の周面に接触させた状態とする。なお、判定治具２０を速度検出器１０側に近づける方法は任意であり、機械的な動力を用いて行ってもよいし、作業者が手作業で行うようにしてもよい。 When determining the degree of wear of the elastic rotator 13 of the speed detector 10 by the wear determination device of the present embodiment, first, the determination jig 20 configured as described above is brought close to the speed detector 10 side, and then the elastic rotator is selected. Match to 13. At this time, the one end surface 21 a of the plate-like member 21 in which a part of the circular recess 22 is opened is brought into contact with the peripheral surface of the rotor 6. The method for bringing the determination jig 20 closer to the speed detector 10 is arbitrary, and may be performed using mechanical power, or may be performed manually by an operator.

次に、判定治具２０の厚み方向に貫通する軸挿通孔２３に弾性回転体１３の回転中心軸１２を挿通し、弾性回転体１３に対する判定治具２０の位置合わせを行う。そして、この状態でさらに判定治具２０を弾性回転体１３側に押し込む。このとき、弾性回転体１３の磨耗が許容磨耗範囲を超えるほどにまで進行していれば、磨耗計測部として板状部材２１に凹設した円形凹部２２内に弾性回転体１３が入り込むことになる。一方、弾性回転体１３の磨耗度合いが許容磨耗範囲内であれば、弾性回転体１３の外周部分が円形凹部２２の外周端縁に干渉することになる。したがって、弾性回転体１３が判定治具２０の円形凹部２２に干渉するか否かにより、弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定することができる。 Next, the rotation center shaft 12 of the elastic rotator 13 is inserted into the shaft insertion hole 23 penetrating in the thickness direction of the determination jig 20, and the determination jig 20 is aligned with the elastic rotator 13. In this state, the determination jig 20 is further pushed into the elastic rotator 13 side. At this time, if the abrasion of the elastic rotator 13 has progressed to the extent that it exceeds the allowable wear range, the elastic rotator 13 will enter the circular recess 22 provided in the plate-like member 21 as a wear measuring portion. . On the other hand, if the degree of wear of the elastic rotating body 13 is within the allowable wear range, the outer peripheral portion of the elastic rotating body 13 interferes with the outer peripheral edge of the circular recess 22. Therefore, whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range can be determined based on whether or not the elastic rotating body 13 interferes with the circular recess 22 of the determination jig 20.

以上説明したように、本実施形態の磨耗判定装置によれば、弾性回転体１３の許容磨耗範囲に対応した大きさの円形凹部２２（磨耗計測部）が形成された判定治具２０を弾性回転体１３に突き合わせ、弾性回転体１３が円形凹部２２の外周端縁に干渉するか否かにより弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定するようにしているので、弾性回転体１３に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる。特に、この磨耗判定装置では、判定治具２０の軸挿通孔２３に弾性回転体１３の回転中心軸１２を挿通させるだけで弾性回転体１３に対する判定治具２０の位置合わせが正確に行われ、また、弾性回転体１３を取り外すことなくロータ６に当接させたままの状態で磨耗度合いを判定できるので、磨耗判定の作業を極めて簡便に行うことができる。 As described above, according to the wear determination device of the present embodiment, the determination jig 20 having the circular recess 22 (wear measurement portion) having a size corresponding to the allowable wear range of the elastic rotator 13 is elastically rotated. Since the elastic rotating body 13 is abutted against the body 13 and whether the elastic rotating body 13 interferes with the outer peripheral edge of the circular recess 22 or not, it is determined whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range. It can be accurately and easily determined whether or not the elastic rotating body 13 is worn beyond the allowable wear range. In particular, in this wear determination device, the positioning of the determination jig 20 with respect to the elastic rotator 13 is accurately performed only by inserting the rotation center shaft 12 of the elastic rotator 13 through the shaft insertion hole 23 of the determination jig 20. In addition, since the degree of wear can be determined while the elastic rotating body 13 is kept in contact with the rotor 6 without being removed, the wear determination can be performed very simply.

［第２の実施形態］
次に、本発明の第２の実施形態について説明する。本実施形態の磨耗判定装置は、判定治具の構成が上述した第１の実施形態とは異なるものである。 [Second Embodiment]
Next, a second embodiment of the present invention will be described. The wear determination device of this embodiment is different from the first embodiment described above in the configuration of the determination jig.

図４は本実施形態の磨耗判定装置に用いる判定治具の斜視図であり、図５は同判定治具の側面図である。本実施形態の磨耗判定装置では、図４及び図５に示すように、板状部材３１の厚み方向に貫通形成された円形の貫通孔３２を上記の磨耗計測部とした判定治具３０を用いる。すなわち、本実施形態の磨耗判定装置で用いる判定治具３０は、例えば金属や合成樹脂などの所定の剛性を有する部材が矩形板状に成形されてなる板状部材３１を母材とし、この板状部材３１の厚み方向に貫通するように、弾性回転体１３の許容磨耗範囲に対応した大きさ（許容磨耗範囲の最大限まで磨耗が進行した弾性回転体１３と略同じ大きさ）の円形貫通孔３２が形成されている。また、板状部材３１の一端面３１ａは、ロータ６の周面に倣う曲率の円弧形状に成形されており、この板状部材３１の一端面３１ａをロータ６の周面に接触させた状態で、ロータ６の周面上における円形貫通孔３２の高さ位置が弾性回転体１３の位置と一致するようになっている。 FIG. 4 is a perspective view of a determination jig used in the wear determination apparatus of the present embodiment, and FIG. 5 is a side view of the determination jig. In the wear determination apparatus of this embodiment, as shown in FIGS. 4 and 5, a determination jig 30 is used in which a circular through-hole 32 formed through in the thickness direction of the plate-like member 31 is used as the wear measurement unit. . That is, the determination jig 30 used in the wear determination apparatus of the present embodiment uses, as a base material, a plate-like member 31 formed by forming a member having a predetermined rigidity such as metal or synthetic resin into a rectangular plate shape. Circular penetration of a size corresponding to the allowable wear range of the elastic rotator 13 (substantially the same size as the elastic rotator 13 in which wear has progressed to the maximum allowable wear range) so as to penetrate in the thickness direction of the member 31 A hole 32 is formed. Further, the one end surface 31 a of the plate-like member 31 is formed in an arc shape having a curvature following the peripheral surface of the rotor 6, and the one end surface 31 a of the plate-like member 31 is in contact with the peripheral surface of the rotor 6. The height position of the circular through-hole 32 on the peripheral surface of the rotor 6 matches the position of the elastic rotator 13.

本実施形態の磨耗判定装置により速度検出器１０の弾性回転体１３の磨耗度合いを判定する場合、まず、以上の構成とされた判定治具３０を、円弧形状に成形された板状部材３１の一端面３１ａをロータ６の周面に接触させながら速度検出器１０側にスライドさせて、弾性回転体１３に突き合わせる。なお、判定治具３０を速度検出器１０側にスライドさせる方法は任意であり、機械的な動力を用いて行ってもよいし、作業者が手作業で行うようにしてもよい。 When determining the degree of wear of the elastic rotating body 13 of the speed detector 10 by the wear determination device of the present embodiment, first, the determination jig 30 having the above-described configuration is used for the plate-shaped member 31 formed into an arc shape. The one end surface 31 a is slid toward the speed detector 10 while being brought into contact with the peripheral surface of the rotor 6, and is abutted against the elastic rotor 13. The method of sliding the determination jig 30 toward the speed detector 10 is arbitrary, and may be performed using mechanical power or may be performed manually by an operator.

次に、この判定治具３０の磨耗計測部として板状部材３１の厚み方向に貫通形成した円形貫通孔３２が弾性回転体１３に対して正対するように、目視により弾性回転体１３に対する判定治具３０の位置を調整し、この状態でさらに判定治具３０を弾性回転体１３側に押し込む。このとき、弾性回転体１３の磨耗が許容磨耗範囲を超えるほどにまで進行していれば、判定治具３０の円形貫通孔３２内に弾性回転体１３が入り込むことになる。一方、弾性回転体１３の磨耗度合いが許容磨耗範囲内であれば、弾性回転体１３の外周部分が円形貫通孔３２の外周端縁に干渉することになる。したがって、弾性回転体１３が判定治具３０の円形貫通孔３２に干渉するか否かにより、弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定することができる。 Next, the determination for the elastic rotating body 13 is visually observed so that the circular through hole 32 formed through the plate-shaped member 31 in the thickness direction as the wear measuring portion of the determining jig 30 faces the elastic rotating body 13. The position of the tool 30 is adjusted, and the determination jig 30 is further pushed into the elastic rotating body 13 in this state. At this time, if the abrasion of the elastic rotator 13 has progressed to the extent that it exceeds the allowable wear range, the elastic rotator 13 enters the circular through hole 32 of the determination jig 30. On the other hand, when the degree of wear of the elastic rotating body 13 is within the allowable wear range, the outer peripheral portion of the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 32. Therefore, whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range can be determined based on whether or not the elastic rotating body 13 interferes with the circular through hole 32 of the determination jig 30.

以上説明したように、本実施形態の磨耗判定装置によれば、弾性回転体１３の許容磨耗範囲に対応した大きさの円形貫通孔３２（磨耗計測部）が形成された判定治具３０を弾性回転体１３に突き合わせ、弾性回転体１３が円形貫通孔３２の外周端縁に干渉するか否かにより弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定するようにしているので、上述した第１の実施形態と同様に、弾性回転体１３に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる。特に、この磨耗判定装置では、判定治具３０の板状部材３１の一端面３１ａがロータ６の周面に倣う曲率の円弧形状に成形されているので、弾性回転体１３に対する判定治具３０の位置合わせが極めて容易であり、また、弾性回転体１３を取り外すことなくロータ６に当接させたままの状態で磨耗度合いを判定できるので、磨耗判定の作業を極めて簡便に行うことができる。 As described above, according to the wear determination device of the present embodiment, the determination jig 30 in which the circular through hole 32 (wear measurement unit) having a size corresponding to the allowable wear range of the elastic rotating body 13 is formed is elastic. Abutting against the rotating body 13, it is determined whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range depending on whether or not the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 32. Therefore, similarly to the above-described first embodiment, it can be accurately and easily determined whether or not the elastic rotating body 13 is worn beyond the allowable wear range. In particular, in this wear determination device, since the one end surface 31a of the plate-like member 31 of the determination jig 30 is formed in an arc shape having a curvature that follows the peripheral surface of the rotor 6, the determination jig 30 with respect to the elastic rotating body 13 is provided. Positioning is extremely easy, and the degree of wear can be determined while the elastic rotating body 13 is kept in contact with the rotor 6 without removing the elastic rotating body 13. Therefore, the wear determination can be performed very simply.

［第３の実施形態］
次に、本発明の第３の実施形態について説明する。本実施形態の磨耗判定装置は、判定治具をロータ６の周面上に支持する支持部材を備え、この支持部材に、ロータ６の周面上における判定治具の高さ位置を調整する高さ調整機構を設けたものである。 [Third Embodiment]
Next, a third embodiment of the present invention will be described. The wear determination device of the present embodiment includes a support member that supports the determination jig on the circumferential surface of the rotor 6, and a height that adjusts the height position of the determination jig on the circumferential surface of the rotor 6. A height adjusting mechanism is provided.

図６は、本実施形態の磨耗判定装置を示す斜視図である。本実施形態の磨耗判定装置では、板状部材４１の厚み方向に貫通形成された円形の貫通孔４２を上記の磨耗計測部とした判定治具４０を用いる。すなわち、本実施形態の磨耗判定装置で用いる判定治具４０は、第２の実施形態で説明した判定治具３０と同様に、例えば金属や合成樹脂などの所定の剛性を有する部材が矩形板状に成形されてなる板状部材４１を母材とし、この板状部材４１の厚み方向に貫通するように、弾性回転体１３の許容磨耗範囲に対応した大きさ（許容磨耗範囲の最大限まで磨耗が進行した弾性回転体１３と略同じ大きさ）の円形貫通孔４２が形成されている。ただし、この判定治具４０では、ロータ６の周面に接触する板状部材４１の一端面４１ａはフラットな平坦面とされている。 FIG. 6 is a perspective view showing the wear determination device of the present embodiment. In the wear determination apparatus of the present embodiment, the determination jig 40 using the circular through hole 42 penetratingly formed in the thickness direction of the plate-like member 41 as the wear measurement unit is used. That is, the determination jig 40 used in the wear determination apparatus of this embodiment is a rectangular plate-like member having a predetermined rigidity, such as metal or synthetic resin, like the determination jig 30 described in the second embodiment. A size corresponding to the allowable wear range of the elastic rotating body 13 (wear to the maximum of the allowable wear range) so as to penetrate the plate-shaped member 41 formed in the thickness direction of the plate-shaped member 41 in the thickness direction. A circular through hole 42 having a size substantially the same as that of the elastic rotating body 13 having undergone the above-described process is formed. However, in this determination jig 40, the one end surface 41a of the plate-like member 41 that contacts the circumferential surface of the rotor 6 is a flat flat surface.

また、判定治具４０を構成する板状部材４１の左右側面には、ネジ孔が形成された一対のアーム４３ａ，４３ｂが各々接合されており、各アーム４３ａ，４３ｂのネジ孔に、それぞれ蝶ネジなどのネジ部材４４ａ，４４ｂが螺合されている。これらアーム４３ａ，４３ｂのネジ孔に螺合されるネジ部材４４ａ，４４ｂの先端部には、それぞれマグネット４５ａ，４５ｂが装着されている。以上の構成の磨耗判定装置において、一対のアーム４３ａ，４３ｂとネジ部材４４ａ，４４ｂ及びマグネット４５ａ，４５ｂとが上記の支持部材として機能する。また、ネジ部材４４ａ，４４ｂは上記の高さ調整機構としての機能も有する。なお、判定治具としては、上記の判定治具４０に代えて、第１の実施形態で説明した判定治具２０や第２の実施形態で説明した判定治具３０を用いることも可能である。 A pair of arms 43a and 43b formed with screw holes are respectively joined to the left and right side surfaces of the plate-like member 41 constituting the determination jig 40, and the butterflies are respectively connected to the screw holes of the arms 43a and 43b. Screw members 44a and 44b such as screws are screwed together. Magnets 45a and 45b are mounted on the tip ends of screw members 44a and 44b that are screwed into the screw holes of the arms 43a and 43b, respectively. In the wear determination apparatus having the above configuration, the pair of arms 43a and 43b, the screw members 44a and 44b, and the magnets 45a and 45b function as the support member. Further, the screw members 44a and 44b also have a function as the height adjusting mechanism. As the determination jig, the determination jig 20 described in the first embodiment or the determination jig 30 described in the second embodiment can be used instead of the determination jig 40 described above. .

本実施形態の磨耗判定装置により速度検出器１０の弾性回転体１３の磨耗度合いを判定する場合、まず、アーム４３ａ，４３ｂ及びネジ部材４４ａ，４４ｂが取り付けられた判定治具４０を速度検出器１０側に近づけて、ネジ部材４４ａ，４４ｂの先端部に装着されたマグネット４５ａ，４５ｂの磁気吸着力により、判定治具４０を弾性回転体１３に突き合わせた状態でロータ６の周面上に設置する。 In the case of determining the degree of wear of the elastic rotor 13 of the speed detector 10 by the wear determination device of the present embodiment, first, the speed detector 10 uses the determination jig 40 to which the arms 43a and 43b and the screw members 44a and 44b are attached. The determination jig 40 is placed on the circumferential surface of the rotor 6 in a state of being abutted against the elastic rotating body 13 by the magnetic attraction force of the magnets 45a and 45b attached to the tip portions of the screw members 44a and 44b. .

次に、この判定治具４０の磨耗計測部として板状部材４１の厚み方向に貫通形成した円形貫通孔４２が弾性回転体１３に対して正対するように、目視により弾性回転体１３に対する判定治具４０の位置を調整し、さらに、ネジ部材４４ａ，４４ｂの押し込み量を調整することにより、判定治具４０の高さ位置を調整する。そして、この状態でさらに判定治具４０を弾性回転体１３側に押し込む。このとき、弾性回転体１３の磨耗が許容磨耗範囲を超えるほどにまで進行していれば、判定治具４０の円形貫通孔４２内に弾性回転体１３が入り込むことになる。一方、弾性回転体１３の磨耗度合いが許容磨耗範囲内であれば、弾性回転体１３の外周部分が円形貫通孔４２の外周端縁に干渉することになる。したがって、弾性回転体１３が判定治具４０の円形貫通孔４２に干渉するか否かにより、弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定することができる。 Next, the determination of the elastic rotator 13 is visually confirmed so that the circular through hole 42 formed in the thickness direction of the plate-like member 41 faces the elastic rotator 13 as a wear measuring portion of the determination jig 40. The height position of the determination jig 40 is adjusted by adjusting the position of the tool 40 and further adjusting the pushing amount of the screw members 44a and 44b. In this state, the determination jig 40 is further pushed into the elastic rotator 13 side. At this time, if the abrasion of the elastic rotator 13 has progressed to the extent that it exceeds the allowable wear range, the elastic rotator 13 enters the circular through hole 42 of the determination jig 40. On the other hand, if the degree of wear of the elastic rotating body 13 is within the allowable wear range, the outer peripheral portion of the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 42. Therefore, whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range can be determined based on whether or not the elastic rotating body 13 interferes with the circular through hole 42 of the determination jig 40.

以上説明したように、本実施形態の磨耗判定装置によれば、弾性回転体１３の許容磨耗範囲に対応した大きさの円形貫通孔４２（磨耗計測部）が形成された判定治具４０を弾性回転体１３に突き合わせ、弾性回転体１３が円形貫通孔４２の外周端縁に干渉するか否かにより弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定するようにしているので、上述した第１の実施形態及び第２の実施形態と同様に、弾性回転体１３に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる。特に、この磨耗判定装置では、判定治具４０に接合されたアーム４３ａ，４３ｂやネジ部材４４ａ，４４ｂ、マグネット４５ａ，４５ｂによって判定治具４０がロータ６の周面上に支持され、ネジ部材４３ａ，４３ｂの押し込み量の調整によって判定治具４０の高さ位置が調整されるので、弾性回転体１３に対する判定治具４０の位置合わせが極めて容易であり、また、弾性回転体１３を取り外すことなくロータ６に当接させたままの状態で磨耗度合いを判定できるので、磨耗判定の作業を極めて簡便に行うことができる。 As described above, according to the wear determination device of the present embodiment, the determination jig 40 in which the circular through hole 42 (wear measurement unit) having a size corresponding to the allowable wear range of the elastic rotating body 13 is formed is elastic. Abutting against the rotating body 13, it is determined whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range depending on whether the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 42. Therefore, similarly to the first embodiment and the second embodiment described above, it is possible to accurately and easily determine whether or not the elastic rotating body 13 is worn beyond the allowable wear range. In particular, in this wear determination apparatus, the determination jig 40 is supported on the peripheral surface of the rotor 6 by the arms 43a and 43b, the screw members 44a and 44b, and the magnets 45a and 45b joined to the determination jig 40, and the screw member 43a. , 43b is adjusted to adjust the height position of the determination jig 40, so that the alignment of the determination jig 40 with respect to the elastic rotator 13 is extremely easy, and the elastic rotator 13 is not removed. Since the degree of wear can be determined with the rotor 6 kept in contact with the rotor 6, the work of wear determination can be performed very simply.

次に、本発明の第４の実施形態について説明する。本実施形態の磨耗判定装置は、判定治具をロータ６の周面上に支持する支持部材を備え、この支持部材に、ロータ６の周面上における判定治具の高さ位置を調整する高さ調整機構と、判定治具を弾性回転体１３に対して近接離間する方向に移動させるスライド機構とを設けたものである。 [Fourth Embodiment]

図７は、本実施形態の磨耗判定装置を示す斜視図である。本実施形態の磨耗判定装置では、第３の実施形態で説明した判定治具４０と同様の判定治具５０を用いる。すなわち、本実施形態の磨耗判定装置で用いる判定治具５０は、例えば金属や合成樹脂などの所定の剛性を有する部材が矩形板状に成形されてなる板状部材５１を母材とし、この板状部材５１の厚み方向に貫通するように、弾性回転体１３の許容磨耗範囲に対応した大きさ（許容磨耗範囲の最大限まで磨耗が進行した弾性回転体１３と略同じ大きさ）の円形貫通孔５２が形成されている。なお、判定治具としては、第１の実施形態で説明した判定治具２０や第２の実施形態で説明した判定治具３０を用いることも可能である。 FIG. 7 is a perspective view showing the wear determination device of the present embodiment. In the wear determination apparatus of the present embodiment, a determination jig 50 similar to the determination jig 40 described in the third embodiment is used. That is, the determination jig 50 used in the wear determination apparatus of the present embodiment uses, as a base material, a plate-like member 51 formed of a member having a predetermined rigidity such as metal or synthetic resin in a rectangular plate shape.

As the determination jig, the determination jig 20 described in the first embodiment or the determination jig 30 described in the second embodiment can be used.

また、判定治具５０を構成する板状部材５１の左右側面には、先端部に係合突起が形成された一対のアーム５３ａ，５３ｂが接合されており、各アーム５３ａ，５３ｂの先端部の係合突起が、例えばＣ型鋼などからなる一対のスライドレール５４ａ，５４ｂに各々係合されている。また、一対のスライドレール５４ａ，５４ｂには、長手方向の両側にそれぞれネジ孔が形成されており、各スライドレール５４ａ,５４ｂのネジ孔に、それぞれ蝶ネジなどのネジ部材５５ａ〜５５ｄが螺合されている。これらスライドレール５４ａ，５４ｂのネジ孔に螺合されるネジ部材５５ａ〜５５ｄの先端部には、それぞれマグネット５６ａ〜５６ｄが装着されている。以上の構成の磨耗判定装置において、一対のアーム５３ａ，５３ｂとスライドレール５４ａ，５４ｂとネジ部材５５ａ〜５５ｄ及びマグネット５６ａ〜５６ｄとが上記の支持部材として機能する。また、一対のアーム５３ａ，５３ｂ及びスライドレール５４ａ，５４ｂは上記のスライド機構としての機能も有し、また、ネジ部材５５ａ〜５５ｄは上記の高さ調整機構としての機能も有する。 In addition, a pair of arms 53a and 53b having engaging projections formed at the tip portions are joined to the left and right side surfaces of the plate-like member 51 constituting the determination jig 50, and the tip portions of the arms 53a and 53b are joined. The engaging protrusions are respectively engaged with a pair of slide rails 54a and 54b made of, for example, C-shaped steel. The pair of slide rails 54a and 54b are formed with screw holes on both sides in the longitudinal direction, and screw members 55a to 55d such as thumb screws are screwed into the screw holes of the slide rails 54a and 54b, respectively. Has been. Magnets 56a to 56d are mounted on the tip portions of screw members 55a to 55d that are screwed into the screw holes of the slide rails 54a and 54b, respectively. In the wear determination device having the above configuration, the pair of arms 53a and 53b, the slide rails 54a and 54b, the screw members 55a to 55d, and the magnets 56a to 56d function as the support member. The pair of arms 53a and 53b and the slide rails 54a and 54b also have a function as the above-described slide mechanism, and the screw members 55a to 55d also have a function as the above-described height adjusting mechanism.

本実施形態の磨耗判定装置により速度検出器１０の弾性回転体１３の磨耗度合いを判定する場合、まず、判定治具５０に接合されたアーム５３ａ，５３ｂの係合部をスライドレール５４ａ，５４ｂに係合した状態で、ネジ部材５５ａ〜５５ｄの先端部に装着されたマグネット５６ａ〜５６ｄの磁気吸着力により、スライドレール５４ａ，５４ｂ及び判定治具５０をロータ６の周面上に設置する。 When determining the degree of wear of the elastic rotating body 13 of the speed detector 10 by the wear determination device of the present embodiment, first, the engaging portions of the arms 53a and 53b joined to the determination jig 50 are used as the slide rails 54a and 54b. In the engaged state, the slide rails 54a and 54b and the determination jig 50 are installed on the peripheral surface of the rotor 6 by the magnetic attractive force of the magnets 56a to 56d attached to the tip portions of the screw members 55a to 55d.

次に、判定治具５０をスライドレール５４ａ，５４ｂに沿って速度検出器１０に近付く方向に移動させ、弾性回転体１３に突き合わせる。そして、この判定治具５０の磨耗計測部として板状部材５１の厚み方向に貫通形成した円形貫通孔５２が弾性回転体１３に対して正対するように、目視により弾性回転体１３に対する判定治具５０の位置を調整し、さらに、ネジ部材５５ａ〜５５ｄの押し込み量を調整することにより、判定治具５０の高さ位置を調整する。そして、この状態でさらに判定治具５０をスライドレール５４ａ，５４ｂに沿って移動させて弾性回転体１３側に押し込む。このとき、弾性回転体１３の磨耗が許容磨耗範囲を超えるほどにまで進行していれば、判定治具５０の円形貫通孔５２内に弾性回転体１３が入り込むことになる。一方、弾性回転体１３の磨耗度合いが許容磨耗範囲内であれば、弾性回転体１３の外周部分が円形貫通孔５２の外周端縁に干渉することになる。したがって、弾性回転体１３が判定治具５０の円形貫通孔５２に干渉するか否かにより、弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定することができる。 Next, the determination jig 50 is moved along the slide rails 54 a and 54 b in a direction approaching the speed detector 10, and abuts against the elastic rotating body 13. Then, the determination jig for the elastic rotator 13 is visually observed so that the circular through hole 52 formed in the thickness direction of the plate-like member 51 as a wear measuring portion of the determination jig 50 faces the elastic rotator 13. The height position of the determination jig 50 is adjusted by adjusting the position 50 and further adjusting the push-in amounts of the screw members 55a to 55d. In this state, the determination jig 50 is further moved along the slide rails 54a and 54b and pushed into the elastic rotor 13 side. At this time, if the abrasion of the elastic rotator 13 has progressed to such an extent that it exceeds the allowable wear range, the elastic rotator 13 enters the circular through hole 52 of the determination jig 50. On the other hand, if the degree of wear of the elastic rotating body 13 is within the allowable wear range, the outer peripheral portion of the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 52. Therefore, whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range can be determined based on whether or not the elastic rotating body 13 interferes with the circular through hole 52 of the determination jig 50.

以上説明したように、本実施形態の磨耗判定装置によれば、弾性回転体１３の許容磨耗範囲に対応した大きさの円形貫通孔５２（磨耗計測部）が形成された判定治具５０を弾性回転体１３に突き合わせ、弾性回転体１３が円形貫通孔５２の外周端縁に干渉するか否かにより弾性回転体１３の磨耗度合いが許容磨耗範囲を超えているか否かを判定するようにしているので、上述した第１乃至第３の実施形態と同様に、弾性回転体１３に許容磨耗範囲を超える磨耗が生じているかどうかを正確且つ簡便に判定することができる。特に、この磨耗判定装置では、判定治具５０に接合されたアーム５３ａ，５３ｂやスライドレール５４ａ，５４ｂ、ネジ部材５５ａ〜５５ｄ、マグネット５６ａ〜５６ｄによって判定治具５０がロータ６の周面上に支持され、判定治具５０をスライドレール５４ａ，５４ｂに沿って弾性回転体１３側に移動可能に構成されているとともに、ネジ部材５５ａ〜５５ｄの押し込み量の調整によって判定治具５０の高さ位置の調整を可能にしているので、弾性回転体１３に対する判定治具５０の位置合わせが極めて容易であり、また、弾性回転体１３を取り外すことなくロータ６に当接させたままの状態で磨耗度合いを判定できるので、磨耗判定の作業を極めて簡便に行うことができる。 As described above, according to the wear determination device of the present embodiment, the determination jig 50 in which the circular through hole 52 (wear measurement unit) having a size corresponding to the allowable wear range of the elastic rotating body 13 is formed is elastic. Abutting against the rotating body 13, it is determined whether or not the degree of wear of the elastic rotating body 13 exceeds the allowable wear range depending on whether the elastic rotating body 13 interferes with the outer peripheral edge of the circular through hole 52. Therefore, similarly to the first to third embodiments described above, it is possible to accurately and easily determine whether or not the elastic rotating body 13 is worn beyond the allowable wear range. In particular, in this wear determination apparatus, the determination jig 50 is placed on the circumferential surface of the rotor 6 by the arms 53a, 53b and slide rails 54a, 54b, screw members 55a-55d, and magnets 56a-56d joined to the determination jig 50. The determination jig 50 is supported so as to be movable along the slide rails 54a and 54b toward the elastic rotator 13, and the height position of the determination jig 50 is adjusted by adjusting the pushing amount of the screw members 55a to 55d. Therefore, the positioning of the determination jig 50 with respect to the elastic rotator 13 is extremely easy, and the degree of wear is kept in contact with the rotor 6 without removing the elastic rotator 13. Therefore, the wear determination operation can be performed very simply.
