Abstract

A bearing shaft locking feature that prevents or limits radial movement during operation is disclosed. The bearing shaft locking feature reduces wear and mechanical noise in drive based systems. This design utilizes a set screw to provide force through a special locking block to prevent radial and axial movement between the shaft and a bearing inner race. This approach allows an improved way of maintaining the location of a component on a shaft with a flat. This design is cost effective compared to currently available designs and improves run out control between shaft and bearing support. Service cost is potentially lower and overcomes component wear. Field replacement of components is easier and requires no special tooling and all items of the design are reusable.
