COMPRESSOR CRANKSHAFT WITH BEARING SLEEVE AND ASSEMBLY METHOD

摘要

A compressor assembly having a drive shaft supported by a main bearing and an outboard bearing located on opposite axial ends of a cylinder block. The mai n bearing has a bearing support formed therein in which first and second apertures are defined. The diameter of the first aperture is less than the diameter of the second aperture. The shaft extends through the first and second apertures with the diameter of the drive shaft having an outer diameter which is no greater than the diameter of the first aperture. A slee ve is mounted on the drive shaft and is at least partially disposed within the second apertur e. A bearing is located in the second aperture and engages the sleeve and the main bearing t o rotationally support the drive shaft. The sleeve can have a thickness which allows the bearing to be of a standard size rather than a custom size.
