Abstract:

A hydraulically actuated device for applying a test load to a bearing or the like to prove the integrity of its mounting or staking within a bore in a housing such as a gear case or the like. To accommodate limited access situations the device is constructed in a right angle configuration in which a hydraulic cylinder 21 applies axial pressure to a first thrust rod assembly which includes first thrust rod 18 through threaded spindle 22 driving a linearly translated cam 32 engaging a cam follower wheel 36 to transfer the translation to a second thrust rod assembly which includes a horizontal shaft 38 and spindle 45 within a cross-arm housing portion 11 and a tubular housing portion 17. The same second thrust direction applies the bearing loading in either of two directions depending upon the shape of the interface parts comprising interface part 57, washer 58, and interface part 60 at the extremities of the spindle 45 and its tubular housing portion 17. The interface parts can bear on the bearing under test from either side thereof with respect to the bearing mounting structural part 51.
