Estimating the term…
Abstract
A scroll compressor includes an Oldham coupling which prevents the orbiting scroll member from rotating when driven by a rotating shaft. The Oldham coupling is formed of titanium or titanium alloy, thus increasing the strength of the Oldham coupling while minimizing its weight. Reduced coupling weight minimizes unnecessary scroll compressor vibration.
Claims11
A scroll compressor comprising:
- a first scroll member having a base and a generally spiral wrap extending from its base;
- a second scroll member having a base and a generally spiral wrap extending from its base;
- said second scroll member being caused to orbit by a rotating driveshaft;
- and
- an Oldham coupling constraining said second scroll member to orbital movement when driven by said rotating driveshaft, said Oldham coupling being formed such that a majority of its body is formed of a titanium material.
