Scroll compressor including oldham coupling having keys that are slidingly received in slots of a non-orbiting scroll and/or an orbiting scroll

摘要

A compression mechanism can include a first scroll member, a second scroll member, and an Oldham coupling. The first scroll member can include a base plate. The second scroll member can meshingly engaged with the first scroll member, and include a first radially extending slot. The Oldham coupling can include a ring portion disposed about the base plate and a first radially extending key portion disposed in the first radially extending slot. The ring portion and the key portion can include a pair of upper surfaces and a pair of lower surfaces. At least one pair of upper surfaces or lower surfaces can be substantially coplanar.

1. A compression mechanism comprising:
an orbiting scroll member including a base plate; a non-orbiting scroll member meshingly engaged with the orbiting scroll member, the non-orbiting scroll member including a first radially extending slot; and an Oldham coupling including a ring portion disposed about the base plate and a first radially extending key portion disposed in the first radially extending slot, the ring portion having a first upper surface and a first lower surface, and the key portion having a second upper surface and a second lower surface, wherein at least one of:
the second upper surface is coplanar with the first upper surface; andthe second lower surface is coplanar with the first lower surface.
