Title: APPARATUS AND METHOD FOR PRELOADING BEARING ASSEMBLIES
Abstract:
An apparatus (10) for preloading a bearing assembly (14) on a shaft (12) includes a first annular threaded member (56) positioned about the shaft (12) and a second annular threaded member (68) positioned about the shaft (12). The first and second threaded members (56,68) have intermeshing threads such that rotation of the second threaded member (68) causes axial translation of the first threaded member (56) to apply a first axial force to the bearing assembly (14) to preload the bearing assembly (14). An actuator is operable to rotate the second threaded member (68) relative to the first threaded member (56) to apply the first axial force to the bearing assembly (14).
