Bearing bush self-adaptive contact friction wear test device

The invention discloses a bearing bush self-adaptive contact friction wear test device, which relates to the field of bearing bush friction wear experiment test equipment, and mainly comprises a motor, a coupler, a torque sensor, a slip ring, a transmission shaft, a turntable, a linear bearing, a slide bar, a ball rod joint bearing, an expansion sleeve, a radial joint bearing, a bearing bush clamp, a triangular block, a force transmission plate, an air cylinder and the like. The ring sample and the bearing bush sample in the device are in sliding friction. By adding the self-adaptive contact device, the ring sample and the bearing bush sample are in full-time stable contact, the eccentric wear phenomenon is overcome, and the accuracy of a friction wear test result is improved; the loading and unloading stability of the device is improved by additionally arranging the spring at the triangular block for lifting the bearing bush clamp; oil outlets are formed in different height positions of the bearing bush clam
