Abstract
An improved Oldham coupling ring is relatively easy to manufacture. Opposed circular arc portions are connected by angled portions to opposed flat portions. The circular arc portions are centered on a common center. As such, the invention is relatively easy to manufacture when compared to prior art systems.
Claims6
A scroll compressor comprising:
- a first scroll member having a base and a generally spiral wrap extending from said base;
- a second scroll member having a base and a generally spiral wrap extending from said base, said wraps of said first and second scroll member interfitting to define compression chambers;
- a shaft driven to rotate, said shaft being operatively connected to drive said second scroll member,
- a crankcase for supporting said second scroll member;
- and
- an Oldham coupling ring positioned between a guiding structure and said second scroll member, said Oldham coupling ring having diametrically opposed circular portions centered on a common point, and having flat portions spaced by 90° from said circular portions, said flat portions being connected to circumferential ends of said circular portion by angled portions, said angled portions being line segments which are not parallel to said flat portion, and said Oldham coupling ring being operatively connected to both said guiding structure and said second scroll member to cause said second scroll member to orbit when said shaft rotates.
