ABSTRACT:
A scroll machine has an elastomeric member placed between the drive shaft and an unloader drive bushing of the scroll machine. The elastomeric member provides limited transverse movement between the drive shaft and the orbiting scroll member which is driven by the drive bushing. The limited transverse movement permits radial compliant engagement of the scroll wraps of the scroll machine. In one embodiment, the elastomeric member is connected to the drive shaft and a bearing plate is placed between the elastomeric member and the drive bushing for driving engagement. In another embodiment, the elastomeric member is connected to the drive bushing and a bearing plate is placed between the elastomeric member and the drive shaft for driving engagement.
