Description

本発明は、両回転スクロール型圧縮機に関するものである。   The present invention relates to a double-rotating scroll compressor.

従来より、両回転スクロール型圧縮機が知られている（特許文献１参照）。これは、駆動側スクロールと、駆動側スクロールと共に同期して回転する従動側スクロールとを備え、駆動側スクロールを回転させる駆動軸に対して、従動側スクロールの回転を支持する従動軸を旋回半径分だけオフセットして、駆動軸と従動軸とを同じ方向に同一角速度で回転させている。   Conventionally, a double-rotation scroll compressor is known (see Patent Document 1). This comprises a drive-side scroll and a driven-side scroll that rotates synchronously with the drive-side scroll, and the driven shaft that supports the rotation of the driven-side scroll is divided by a turning radius relative to the drive shaft that rotates the drive-side scroll. The drive shaft and the driven shaft are rotated at the same angular velocity in the same direction with an offset of only.

特許第５４４３１３２号公報Japanese Patent No. 5443132

両回転スクロール型圧縮機は、駆動側スクロールや従動側スクロールの渦巻状壁体の先端がサポート部材によって支持される構造が採用される場合がある。このような構造を採用する場合、渦巻状壁体の噛み合いを確実にするため、駆動側スクロール及び従動側スクロールの回転軸線周りの位相を正確に位置決めする位置決めピンが設けられる。しかし、位置決めピンを渦巻状壁体に圧入すると、壁体が変形して壁体同士の噛み合いが損なわれ、性能や耐久性が低下するおそれがある。   The double-rotating scroll compressor may employ a structure in which the tip of the spiral wall of the driving scroll or the driven scroll is supported by a support member. When such a structure is employed, a positioning pin for accurately positioning the phase around the rotation axis of the drive side scroll and the driven side scroll is provided in order to ensure the engagement of the spiral wall body. However, when the positioning pin is press-fitted into the spiral wall body, the wall body is deformed and the meshing between the wall bodies is impaired, and there is a possibility that the performance and durability are lowered.

本発明は、このような事情に鑑みてなされたものであって、壁体を位置決めピンで位置決めする際に性能や耐久性を低下させるおそれがない両回転スクロール型圧縮機を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a double-rotating scroll compressor that does not have a risk of reducing performance and durability when positioning a wall body with a positioning pin. And

上記課題を解決するために、本発明の両回転スクロール型圧縮機は以下の手段を採用する。
すなわち、本発明にかかる両回転スクロール型圧縮機は、駆動部によって回転駆動され、駆動側端板に配置された渦巻状の駆動側壁体を有する駆動側スクロール部材と、従動側端板に配置され、前記駆動側壁体に対応する従動側壁体を有し、該従動側壁体が前記駆動側壁体に対して噛み合わされることによって圧縮室を形成する従動側スクロール部材と、前記駆動側スクロール部材と前記従動側スクロール部材とが同じ方向に同一角速度で自転運動するように前記駆動側スクロール部材から前記従動側スクロール部材に駆動力を伝達する同期駆動機構とを備え、前記駆動側壁体または前記従動側壁体の少なくともいずれか一方の軸方向における先端に対して、回転軸線周りの位相を位置決めする位置決めピンによって接続されて該壁体とともに回転するサポート部材が設けられ、前記位置決めピンは、前記サポート部材に対して圧入されるとともに、前記壁体に対して非圧入状態で嵌入されていることを特徴とする。 In order to solve the above problems, the double-rotating scroll compressor of the present invention employs the following means.
That is, the double-rotating scroll compressor according to the present invention is disposed on the driven-side end plate and the driven-side scroll member having a spiral drive side wall body that is rotationally driven by the drive unit and disposed on the driving-side end plate. A driven side scroll member corresponding to the drive side wall body, the driven side wall member meshing with the drive side wall body to form a compression chamber, the driven side scroll member, A synchronous drive mechanism for transmitting a driving force from the drive-side scroll member to the driven-side scroll member so that the driven-side scroll member rotates in the same direction at the same angular velocity, and the drive side wall body or the driven side wall body With the wall body connected to the tip in at least one of the axial directions by a positioning pin for positioning the phase around the rotation axis Provided support members rotating, the positioning pins, while being pressed against the support member, characterized in that it is fitted in a non-pressed state with respect to the wall.

駆動側スクロール部材の端板に配置された駆動側壁体と、従動側スクロール部材の対応する従動側壁体とが噛み合わされる。駆動側スクロール部材は、駆動部によって回転駆動され、駆動側スクロール部材に伝達された駆動力は、同期駆動機構を介して従動側スクロール部材に伝達される。これにより、従動側スクロール部材は、回転するとともに駆動側スクロール部材に対して同じ方向に同一角速度で自転運動を行う。このように、駆動側スクロール部材及び従動側スクロール部材の両方が回転する両回転式のスクロール型圧縮機が提供される。
壁体とサポート部材とが位置決めピンによって接続されている。位置決めピンは、サポート部材に対して圧入されている一方で、壁体に対しては非圧入状態で嵌入されている。これにより、サポート部材に対しては位置決めピンを強固に固定でき、かつ壁体には位置決めピンの嵌入による形状変形を及ぼすことがない。壁体に形状変形が生じないので、性能や耐久性の低下を来すおそれがない。
なお、「非圧入状態で嵌入」とは、位置決めピンが嵌め合わさることでピン穴が変形拡大し部材の形状変形を及ぼさない程度の嵌入を意味し、例えばすき間ばめが挙げられる。 The drive side wall disposed on the end plate of the drive side scroll member and the corresponding driven side wall of the driven side scroll member are engaged with each other. The drive side scroll member is rotationally driven by the drive unit, and the driving force transmitted to the drive side scroll member is transmitted to the driven side scroll member via the synchronous drive mechanism. Thereby, the driven scroll member rotates and rotates with the same angular velocity in the same direction with respect to the drive scroll member. Thus, a double-rotation scroll compressor in which both the drive-side scroll member and the driven-side scroll member rotate is provided.
The wall body and the support member are connected by a positioning pin. While the positioning pin is press-fitted into the support member, the positioning pin is fitted into the wall body in a non-press-fitted state. Thereby, the positioning pin can be firmly fixed to the support member, and the wall body is not deformed by the insertion of the positioning pin. Since shape deformation does not occur in the wall, there is no risk of performance or durability degradation.
Note that “insertion in a non-pressed state” means insertion that does not cause deformation of the pin hole and deformation of the member by fitting the positioning pin, and includes, for example, a clearance fit.

さらに、本発明の両回転スクロール型圧縮機では、前記位置決めピンは、前記回転軸線周りに少なくとも２箇所設けられていることを特徴とする。   Furthermore, in the double-rotating scroll compressor of the present invention, the positioning pin is provided at least at two locations around the rotational axis.

位置決めピンを２箇所設けることによって回転軸線回りの位置を決めることができる。   By providing two positioning pins, the position around the rotation axis can be determined.

さらに、本発明の両回転スクロール型圧縮機では、前記駆動側スクロール部材は、第１駆動側端板と第１駆動側壁体とを有し、前記駆動部によって駆動される第１駆動側スクロール部と、第２駆動側端板と第２駆動側壁体とを有する第２駆動側スクロール部と、を備え、前記従動側スクロール部材は、前記従動側端板の一側面に設けられ、前記第１駆動側壁体と噛み合う第１従動側壁体と、前記従動側端板の他側面に設けられ、前記第２駆動側壁体と噛み合う第２従動側壁体と、を備え、前記第１駆動側端板を間に介して配置され、前記第１従動側壁体の軸方向の先端側に固定されて前記第１従動側壁体とともに回転する第１サポート部材と、前記第２駆動側端板を間に介して配置され、前記第２従動側壁体の軸方向の先端側に固定されて前記第２従動側壁体とともに回転する第２サポート部材と、を備え、前記位置決めピンは、前記第１従動側壁体と第１サポート部材との間、及び、前記第２従動側壁体と第２サポート部材との間に設けられていることを特徴とする。   Furthermore, in the double-rotating scroll compressor of the present invention, the drive-side scroll member has a first drive-side end plate and a first drive side wall, and is driven by the drive unit. And a second drive side scroll portion having a second drive side end plate and a second drive side wall, wherein the driven side scroll member is provided on one side surface of the driven side end plate, A first driven side wall that meshes with the drive side wall, and a second driven side wall that is provided on the other side surface of the driven side end plate and meshes with the second drive side wall, the first drive side end plate being A first support member disposed between and fixed to the distal end side in the axial direction of the first driven side wall body and rotating together with the first driven side wall body, and the second drive side end plate interposed therebetween Arranged and fixed to the front end side in the axial direction of the second driven side wall body A second support member that rotates together with the second driven side wall body, wherein the positioning pin is between the first driven side wall body and the first support member, and the second driven side wall body and the second support member. It is characterized by being provided between.

従動側スクロール部材が第１従動側壁体と第２従動側壁体とを備える場合には、それぞれが接続されるサポート部材との間に位置決めピンを設ける。   When the driven-side scroll member includes the first driven side wall body and the second driven side wall body, a positioning pin is provided between the support member to which each is connected.

位置決めピンをサポート部材に対して圧入する一方で、壁体に対しては非圧入状態で嵌入することとしたので、性能や耐久性の低下を来すおそれがない。   While the positioning pin is press-fitted into the support member, it is not fitted into the wall body in a non-press-fitted state, so there is no risk of performance or durability degradation.

A first driven side wall 91b is provided on one side of the driven side end plate 90a, and a second driven side wall 92b is provided on the other side of the driven side end plate 90a. The first driven side wall body 91b installed on the motor 5 side from the driven side end plate 90a is meshed with the first driving side wall body 71b of the first driving side scroll portion 71, and from the driven side end plate 90a to the discharge port 3d side. The installed second driven side wall 92 b is engaged with the second drive side wall 72 b of the second drive side scroll portion 72.

従動側スクロール部材９０の軸方向（図において水平方向）における両端には、第１サポート部材３３と第２サポート部材３５とが設けられている。第１サポート部材３３は、モータ５側に配置され、第２サポート部材３５は吐出口３ｄ側に配置されている。   A first support member 33 and a second support member 35 are provided at both ends in the axial direction (horizontal direction in the figure) of the driven scroll member 90. The first support member 33 is disposed on the motor 5 side, and the second support member 35 is disposed on the discharge port 3d side.

第１サポート部材３３は、第１従動側壁体９１ｂの外周側の先端（自由端）に対して第１サポート固定ボルト３４によって固定されており、第２サポート部材３５は、第２従動側壁体９２ｂの外周側の先端（自由端）に対して第２サポート固定ボルト３６によって固定されている。   The first support member 33 is fixed to the outer peripheral end (free end) of the first driven side wall 91b by the first support fixing bolt 34, and the second support member 35 is the second driven side wall 92b. The second support fixing bolt 36 fixes the front end (free end) on the outer peripheral side of the first support fixing bolt.

第１サポート部材３３と第１従動側壁体９１ｂとの間の従動側回転軸線ＣＬ２回りの位置決めは、第１サポート固定ボルト３４とは異なる角度位置に設けられた位置決めピン４０によって行われる。具体的には、図２に示すように、第１従動側壁体９１ｂの先端に形成されたピン挿入穴９１ｂ１内に位置決めピン４０の一端が挿入され、第１サポート部材３３に対して位置決めピン４０の他端が圧入されている。位置決めピン４０は、第１従動側壁体９１ｂのピン挿入穴９１ｂ１に対して、非圧入状態で嵌入されている。すなわち、位置決めピン４０が嵌め合わさることでピン挿入穴９１ｂ１が変形拡大して第１従動側壁体９１ｂの形状変形を及ぼさない程度の嵌め合いで嵌入されている。
位置決めピン４０は、従動側回転軸線ＣＬ２回りに２箇所設けられている。ただし、位置決めピン４０は、３箇所以上設けてもよい。この場合、３つ目以上の位置決めピン４０は実際には位置決めの必要はないので、いわゆるダミーピンとなる。
なお、第２サポート部材３５と第２従動側壁体９２ｂとの間にも同様に位置決めピンが設けられている。 Positioning about the driven side rotation axis CL2 between the first support member 33 and the first driven side wall 91b is performed by a positioning pin 40 provided at an angular position different from the first support fixing bolt 34. Specifically, as shown in FIG. 2, one end of the positioning pin 40 is inserted into a pin insertion hole 91 b 1 formed at the tip of the first driven side wall 91 b, and the positioning pin 40 is inserted into the first support member 33. The other end is press-fitted. The positioning pin 40 is fitted into the pin insertion hole 91b1 of the first driven side wall 91b in a non-pressed state. That is, when the positioning pin 40 is fitted, the pin insertion hole 91b1 is deformed and enlarged so that the first driven side wall 91b is not deformed.
The positioning pins 40 are provided at two locations around the driven side rotation axis CL2. However, three or more positioning pins 40 may be provided. In this case, the third or more positioning pins 40 do not actually need to be positioned, and are so-called dummy pins.
Similarly, positioning pins are provided between the second support member 35 and the second driven side wall 92b.

第１サポート部材３３の中心軸側には、軸部３３ａが設けられており、この軸部３３ａが第１サポート部材用軸受３７を介してハウジング３に対して固定されている。第２サポート部材３５の中心軸側には、軸部３５ａが設けられており、この軸部３５ａが第２サポート部材用軸受３８を介してハウジング３に対して固定されている。これにより、各サポート部材３３、３５を介して、従動側スクロール部材９０は、従動側回転軸線ＣＬ２回りに回転するようになっている。   A shaft portion 33 a is provided on the center shaft side of the first support member 33, and the shaft portion 33 a is fixed to the housing 3 via a first support member bearing 37. A shaft portion 35 a is provided on the center shaft side of the second support member 35, and the shaft portion 35 a is fixed to the housing 3 via a second support member bearing 38. Thus, the driven scroll member 90 rotates around the driven rotation axis CL2 via the support members 33 and 35.

第１サポート部材３３と第１駆動側端板７１ａとの間には、ピンリング機構（同期駆動機構）１５が設けられている。すなわち、第１駆動側端板７１ａに転がり軸受（リング）が設けられ、第１サポート部材３３にピン部材１５ｂが設けられている。ピンリング機構１５によって、駆動側スクロール部材７０から従動側スクロール部材９０へと駆動力が伝達されるとともに、両スクロール部材７０，９０が同じ方向に同一角速度で自転運動される。   A pin ring mechanism (synchronous drive mechanism) 15 is provided between the first support member 33 and the first drive side end plate 71a. That is, a rolling bearing (ring) is provided on the first drive side end plate 71a, and a pin member 15b is provided on the first support member 33. A driving force is transmitted from the driving side scroll member 70 to the driven side scroll member 90 by the pin ring mechanism 15, and both scroll members 70, 90 are rotated in the same direction at the same angular velocity.

上記構成の両回転スクロール型圧縮機１は、以下のように動作する。
モータ５によって駆動軸６が駆動側回転軸線ＣＬ１回りに回転させられると、駆動軸６に接続された第１駆動側軸部７ｃも回転し、これにより駆動側スクロール部材７０が駆動側回転軸線ＣＬ１回りに回転する。駆動側スクロール部材７０が回転すると、駆動力がピンリング機構１５を介して各サポート部材３３，３５から従動側スクロール部材９０へと伝達され、従動側スクロール部材９０が従動側回転軸線ＣＬ２回りに回転する。このとき、ピンリング機構１５のピン部材１５ｂが円形穴の内周面に対して接触しつつ移動することによって、両スクロール部材７０，９０が同じ方向に同一角速度で自転運動を行う。
両スクロール部材７０，９０が自転旋回運動を行うと、ハウジング３の吸入口から吸い込まれた空気が両スクロール部材７０，９０の外周側から吸入され、両スクロール部材７０，９０によって形成された圧縮室に取り込まれる。そして、第１駆動側壁体７１ｂと第１従動側壁体９１ｂとによって形成された圧縮室と、第２駆動側壁体７２ｂと第２従動側壁体９２ｂとによって形成された圧縮室とが別々に圧縮される。それぞれの圧縮室は中心側に移動するにしたがって容積が減少し、これに伴い空気が圧縮される。第１駆動側壁体７１ｂと第１従動側壁体９１ｂとによって圧縮された空気は、従動側端板９０ａに形成された吐出貫通孔９０ｈを通り、第２駆動側壁体７２ｂと第２従動側壁体９２ｂとによって圧縮された空気と合流し、合流後の空気が吐出ポート７２ｄを通り、ハウジング３の吐出口３ｄから外部へと吐出される。吐出された圧縮空気は、図示しない内燃機関へと導かれ、燃焼用空気として用いられる。 The double-rotating scroll compressor 1 having the above-described configuration operates as follows.
When the drive shaft 6 is rotated around the drive-side rotation axis CL1 by the motor 5, the first drive-side shaft portion 7c connected to the drive shaft 6 also rotates, thereby causing the drive-side scroll member 70 to move to the drive-side rotation axis CL1. Rotate around. When the driving scroll member 70 rotates, the driving force is transmitted from the support members 33 and 35 to the driven scroll member 90 via the pin ring mechanism 15, and the driven scroll member 90 rotates about the driven rotation axis CL2. To do. At this time, when the pin member 15b of the pin ring mechanism 15 moves while being in contact with the inner peripheral surface of the circular hole, both scroll members 70 and 90 rotate in the same direction at the same angular velocity.
When the scroll members 70 and 90 rotate and rotate, the air sucked from the suction port of the housing 3 is sucked from the outer peripheral sides of the scroll members 70 and 90 and is formed by the scroll members 70 and 90. Is taken in. The compression chamber formed by the first drive side wall 71b and the first driven side wall 91b and the compression chamber formed by the second drive side wall 72b and the second driven side wall 92b are separately compressed. The Each compression chamber decreases in volume as it moves toward the center, and air is compressed accordingly. The air compressed by the first drive side wall 71b and the first driven side wall 91b passes through the discharge through hole 90h formed in the driven side end plate 90a, and passes through the second drive side wall 72b and the second driven side wall 92b. And the compressed air passes through the discharge port 72d and is discharged from the discharge port 3d of the housing 3 to the outside. The discharged compressed air is guided to an internal combustion engine (not shown) and used as combustion air.

本実施形態によれば、以下の作用効果を奏する。
従動側壁体９１ｂ，９２ｂと各サポート部材３３，３５との間の位置決めを行う位置決めピン４０を、サポート部材３３，３５に対して圧入する一方で、従動側壁体９１ｂ，９２ｂに対しては非圧入状態で嵌入することとした。これにより、サポート部材３３，３５に対しては位置決めピン４０を強固に固定でき、かつ従動側壁体９１ｂ，９２ｂには位置決めピン４０の嵌入による形状変形を及ぼすことがない。このように、従動側壁体９１ｂ，９２ｂに形状変形が生じないので、両回転スクロール型圧縮機１の性能や耐久性の低下を来すおそれがない。 According to this embodiment, there exist the following effects.
While the positioning pin 40 for positioning the driven side wall bodies 91b and 92b and the support members 33 and 35 is press-fitted into the support members 33 and 35, it is not press-fitted into the driven side wall bodies 91b and 92b. It was decided to insert in the state. Thereby, the positioning pin 40 can be firmly fixed to the support members 33 and 35, and the driven side wall bodies 91b and 92b are not deformed by the insertion of the positioning pin 40. In this way, since the driven side wall bodies 91b and 92b are not deformed, there is no possibility that the performance and durability of the double-rotation scroll compressor 1 will be lowered.

また、図３に示すように、第１サポート部材３３の突出部に別体とされた円柱形状のカラー３３ｂを設け、このカラー３３ｂに対して位置決めピン４０を圧入するようにしても良い。カラー３３ｂが第１サポート部材３３とは別個の部材として設けられているため、第１サポート部材３３の加工が容易となる。また、カラー３３ｂの高さを調整することで、両スクロール部材７０，９０の向かい合う間隔を調整することができる。同様のカラーは、第２サポート部材３５にも設けることができる。   Further, as shown in FIG. 3, a cylindrical collar 33b that is a separate body may be provided on the protruding portion of the first support member 33, and the positioning pin 40 may be press-fitted into the collar 33b. Since the collar 33b is provided as a separate member from the first support member 33, the processing of the first support member 33 is facilitated. Moreover, the space | interval which both the scroll members 70 and 90 face can be adjusted by adjusting the height of the collar 33b. A similar collar can be provided on the second support member 35.

また、図４に示すように、位置決めピン４０は、カラー３３ｂを貫通し、第１サポート部材３３に圧入するようにしても良い。この場合、位置決めピン４０は、カラー３３ｂの貫通穴に対して圧入されていても良いし、すき間ばめとされていても良い。同様のカラーは、第２サポート部材３５にも設けることができる。   Further, as shown in FIG. 4, the positioning pin 40 may penetrate the collar 33 b and press-fit into the first support member 33. In this case, the positioning pin 40 may be press-fitted into the through hole of the collar 33b or may be a clearance fit. A similar collar can be provided on the second support member 35.
