Speed reducer main bearing performance testing device

Abstract

The utility model provides a speed reducer main bearing performance testing device. The speed reducer main bearing performance testing device comprises a workbench, a plurality of groups of cylinders are uniformly mounted at the top of the workbench, a first bearing plate is fixedly mounted on the outer walls of the plurality of groups of cylinders, and bearings are rotatably connected to the outer walls of the upper ends of the plurality of groups of cylinders. According to the speed reducer main bearing performance testing device, the handle is rotated to enable the second rotating shaft to drive the threaded rod to rotate, the threaded rod drives the driving wheel to move along the rectangular groove through the sliding block, the second bearing plate and the motor to tension the transmission belt, and the motor drives the driving wheel to conduct rotation testing on multiple sets of bearings at the same time through the transmission belt. Compared with a spring device for limiting the movement of the driving wheel, the device not only can adjust the tension degree of the transmission belt by adjusting the driving wheel through the interaction of components such as the threaded rod and the sliding block, but also cannot cause the situation that the transmission belt is loosened to affect the bearing test due to the displacement of the driving wheel caused by vibration when the motor works.
