ABSTRACT:
An improved motor coupling and bearing housing are disclosed for a meat deboning machine and the like wherein the motor coupling includes an axially fixed coupling between a drive motor shaft and an auger which accommodates axial movement during thermal expansion to reduce bearing and other parts failure, and allow the drive motor to operate at its magnetic center. A thrust bearing operates between the coupling and is pre-loaded by a biasing force exerted between the coupling and the drive motor shaft which also loads the coupling as it floats over the drive motor shaft. A twist lock connection is made between the coupling and the auger which allows for quick assembly and disassembly while maintaining a good drive connection. An idler housing in conjunction with the motor coupling accommodates thermal expansion of the auger clearance in the motor coupling accommodates small amounts of angular misalignment without placing large forces on the bearings.
