Abstract
A pin-ring mechanism that transmits driving force to cause a driving-side scroll member and a driven-side scroll member to perform rotational movement in a same direction at a same angular velocity is provided. A driving-side end plate includes a ring member installation hole into which a ring member is inserted and installed. The ring member installation hole includes a non-wall-side hole part and a wall-side hole part. The non-wall-side hole part is formed from a non-wall-side surface and has a diameter corresponding to an outer diameter of the ring member. The wall-side hole part is formed from a wall-side surface and has a diameter smaller than the outer diameter of the ring member.
Claims6
A co-rotating scroll compressor, comprising:
- a driving-side scroll member that is rotationally driven by a driving unit and includes a spiral driving-side wall disposed on a driving-side end plate;
- a driven-side scroll member that includes a driven-side wall corresponding to the driving-side wall, the driven-side wall being disposed on a driven-side end plate and engaging with the driving-side wall to form a compression space;
- and
- a synchronous driving mechanism that transmits driving force from the driving-side scroll member to the driven-side scroll member to cause the driving-side scroll member and the driven-side scroll member to perform rotational movement in a same direction at a same angular velocity, wherein
- the synchronous driving mechanism includes a pin member and a ring member, the pin member being fixed to the driving-side wall and/or the driven-side wall and protruding toward the driven-side end plate and/or the driving-side end plate, and the ring member being fixed to the driving-side end plate and/or the driven-side end plate and including an inner peripheral surface coming into contact with the pin member,
- the driving-side end plate and/or the driven-side end plate includes a ring member installation hole into which the ring member is inserted and installed, and
- the ring member installation hole includes a non-wall-side hole part and a wall-side hole part, the non-wall-side hole part being formed from a non-wall-side surface of the driving-side end plate not provided with the driving-side wall and/or a non-wall-side surface of the driven-side end plate not provided with the driven-side wall and having a diameter corresponding to an outer diameter of the ring member, and the wall-side hole part being formed from a wall-side surface of the driving-side end plate provided with the driving-side wall and/or a wall-side surface of the driven-side end plate provided with the driven-side wall and having a diameter smaller than the outer diameter of the ring member.
