ABSTRACT:
A shock absorbing device for sliding bearings, such as hydrostatic bearings or hydrodynamic bearings particularly adapted for absorbing shock loads from a crusher shaft of a bell crusher comprising a base and a first element mounted on the base, a first chamber between the first element and the base of predetermined cross sectional area. The chamber is adapted to be supplied with a fluid under pressure. A second element is mounted between the machine member such as the crusher shaft and the first element and spaced from the latter to define a second chamber in fluid communication with the first chamber. The ball is mounted in a spherical seat in the first element and a piston in the second element engages the ball on the side thereof opposite the seat. Biasing means normally urges the piston against the ball. By this arrangement, load from the crusher shaft which exceeds the biasing force against the ball affects flow of pressure fluid from the second chamber to the first chamber and out through the flow slots between the first element and base.
