ABSTRACT:
A bearing assembly is provided in which bearing preload is exerted by both high and low rate non-linear springs, the low rate springs being substantially collapsed when the preload is applied. A shaft is mounted in two angular contact ball bearings contained in a housing with the bearing outer races maintained a fixed distance apart. The springs are two sets of hard and soft spring washers in tandem each set acting on a respective inner bearing race through the intermediary of a respective thrust member. Mechanical stop faces engage in the event of severe axial loading to prevent such excessive loads from being transmitted through the bearings. The amount of preload applied can be discerned from the width of gaps existing between faces on the thrust members and respective end faces on the housing.
