Scroll Compressor And Oldham Ring And Mating Component For Scroll Compressor

Abstract

The present application relates to a scroll compressor and an Oldham ring and a mating component for the scroll compressor. In the present application, a hollow portion is provided near at least one of engagement walls of a key of the Oldham ring and a corresponding sliding slot of the mating component, so that the at least one engagement wall has a predetermined stiffness and is elastically deformable. As a result, the effective contact area between the Oldham ring and the mating component can be increased, the stress concentration can be reduced, and the wear of the engagement wall can be reduced, thereby improving the performance of the scroll compressor and extending the service life of the scroll compressor.

1 . An Oldham ring for a scroll compressor, comprising:
 an annular body; and   one or more keys protruding from the annular body along an axial direction of the annular body, wherein   the key is configured to be engaged with a corresponding sliding slot of a mating component and has a contact root and a circumferential end surface to be engaged with the sliding slot, wherein at least one of the keys is provided with a hollow portion located at the contact root, and an engagement wall with a predetermined stiffness and being elastically deformable is formed between the hollow portion and the circumferential end surface,   wherein, in the axial direction, the contact root of the key is located near a central part of the hollow portion, and   wherein, in the axial direction, a circumferential width of the central part of the hollow portion is greater than a circumferential width of an end part of the hollow portion.   
     
     
         2 . The Oldham ring according to  claim 1 , wherein a thickness of a radially outer side of the engagement wall is less than or equal to a thickness of a radially inner side of the engagement wall. 
     
     
         3 - 4 . (canceled) 
     
     
         5 . The Oldham ring according to  claim 1 , wherein, in a circumferential direction, a minimum thickness of the engagement wall is less than one third of a circumferential width of the key. 
     
     
         6 . The Oldham ring according to  claim 1 , wherein the hollow portion comprises at least one recessed slot, which is formed on an outer peripheral surface of the key. 
     
     
         7 . The Oldham ring according to  claim 6 , wherein the recessed slot comprises a rectangular recessed slot extending along the axial direction or a circular slot. 
     
     
         8 . The Oldham ring according to  claim 6 , wherein a through hole which is in communication with the recessed slot is formed on an inner peripheral surface of the key. 
     
     
         9 . The Oldham ring according to  claim 6 , wherein the recessed slot extends through a free end surface of the key along the axial direction. 
     
     
         10 . The Oldham ring according to  claim 6 , wherein a depth of the recessed slot in a radial direction is less than a thickness of the engagement wall. 
     
     
         11 - 14 . (canceled) 
     
     
         15 . A scroll compressor, comprising:
 an Oldham ring; and   a mating component configured to be mated with the Oldham ring, wherein   the Oldham ring is the Oldham ring according to  claim 1 .
