Abstract

The invention discloses a bearing pretightening force control device which comprises a shell body, an adjusting ring making contact with the end face of an outer ring of a bearing and a locking device for fixing the adjusting ring in the circumferential direction. The adjusting ring is connected with the shell body in a threaded and matched mode. The locking device comprises a locking pad making contact with the end face of the adjusting ring and a bolt connected with the shell body. The locking pad is provided with a central through hole through which the bolt penetrates. According to technical scheme, the bearing pretightening force control device can adjust the pretightening force of the bearing simply and effectively, the operation procedures of producing pads with different thickness and selecting the pads are avoided, the speed of adjusting the pretightening force of the bearing is improved, and the assembly efficiency of a gearbox is improved. The invention further provides the gearbox with the bearing pretightening force control device.

Description

technical field [0001] The invention relates to the technical field of transmission equipment, in particular to a bearing pretightening force adjustment device and a gearbox. Background technique [0002] Because there is a certain clearance inside the bearing, the contact between the rolling elements of the bearing and the ring will produce elastic deformation under the action of external load. Therefore, during operation, the inner ring and outer ring of the bearing will move relatively, so that the shaft The support rigidity and rotation accuracy of the system are reduced. For shafting components with high precision requirements, a bearing preload adjustment device is often used to preload the bearing to reduce the relative movement between the inner ring and the outer ring of the bearing. [0003] Preload means that when installing bearing components, certain measures are taken to apply axial load to the bearing in advance, so that the internal clearance of the bearing ...
