Scroll Compressor Lower Bearing

摘要

A compressor includes a shell, a motor assembly, a driveshaft, and a bearing assembly. The bearing assembly is disposed within the shell and supports the driveshaft for rotation. The bearing assembly includes a bracket, a hub, and a bushing. The bracket is coupled to the shell and includes an aperture. The hub is disposed within the aperture and defines a bore having a radially inwardly extending lip. The bushing includes a proximal portion and a distal portion. The distal portion of the bushing includes a plurality of radially extending engagement features. The distal portion of the bushing is disposed within the bore of the hub such that the engagement features engage the lip of the hub.
