Bearing Stabilizer

The arrangement shown in the figures is designed to overcome the problem of bearing movement, caused by external vibration such as drive belt tension variation.

A shaft 1 carrying a belt drive pulley 2 is supported in bearing 3 which is a slide fit in housing 4. Radial play 5, shown greatly exaggerated in the figures, is overcome by providing two elastic inserts 6 located in recesses 7 in the bearing housing 4. Initially, the inserts 6 re designed to be flush with, or even below, the housing bore so as not to interfere with the slide fit of the bearing 3.

When the bearing 3 is accurately located axially, the headless set screws 8 are tightened against thrust pads 9 to distort the inserts 6, causing them to protrude into the bore to take up any unwanted radial play 5. This method of bearing stabilization with elastic inserts 6 does not interfere with axial preload on the bearing 3.
