Bayonet spindle mount and a method therefore

摘要

A housing having a spindle mount for mounting a spindle supporting magnetic disks for a magnetic data storage disk system. A bearing cap having seals is mounted on the exterior of the housing. A spindle clamp having a male bayonet mount is inserted through the bearing cap and engages a mounting cup having a female bayonet mount. A belleville washer is mounted onto the clamp between the bearing cap and the head portion of the clamp. The clamp and cup are designed so that the washer is compressed as the bayonet mount engages. This exerts a constant uniform pressure on the bearing cup as well as restraining the bayonet mounting from disengaging. The bearing cap is held tightly against the exterior of the housing as well to seal the bearing and the inner housing from the exterior environment.
