ABSTRACT:
A bearing assembly for a gearbox shaft which is subject to bending forces and capable of absorbing axial forces. The bearing assembly has at least one radial cylindrical roller bearing and two thrust bearings. The inner race of the radial roller bearing is supported radially as well as in one axial direction by the shaft. The thrust bearings are arranged to either side of and supported by a bearing housing that can be attached to the gearbox housing. The thrust bearing closest to the radial cylindrical roller bearing is supported in one axial direction by the inner race of the radial roller bearing. The radial roller bearing and the thrust bearings then are secured against axial movement on the shaft, e.g., by a retaining ring. The bearing housing is designed so that the bearing housing will conform to any inclination of the gearbox shaft due to shaft deflection. For this purpose, the bearing housing may have regions of varying stiffness in the circumferential direction.
