ABSTRACT:
A coupling mechanism for a scroll compressor comprises an orbiting scroll disk, a retention bolt, a bearing shaft and a retention nut. The orbiting scroll disk includes a first face configured to engage a stationary scroll disk to compress a working fluid, and a second face having a hub. The retention bolt is inserted into the hub. The bearing shaft is fit onto the retention bolt and includes a bearing surface for engaging a drive bushing of a drive shaft. The retention nut is threaded onto the retention bolt to retain connection of the bearing shaft with the orbiting scroll disk.
