Abstract
A thermal compensation element that generates an optimal bearing pre-load. The thermal compensation element has a bearing housing with a recess, a bearing outer ring arranged at least partially within the recess, a bearing shaft with a bearing inner ring arranged axially inward of the bearing outer ring, a piston with an outer sealing ring fixed in the recess axially between the bearing housing and the bearing outer ring, and a fluid supply port. The port increases or decreases pressure at the piston via a pressurized medium, allowing adjustable axial forces applied to the end of the hearing shaft by the piston to generate optimal bearing pre-load conditions.
