Abstract

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 clamp, so that the adaptability of a friction-wear test under various lubricating oil quantities is improved; and by simplifying the device and reducing the volume, the assembling easiness and green economy of the test device are improved.

Description

technical field [0001] The invention relates to the field of test equipment for friction and wear of bearing pads, in particular to a friction and wear test device for adaptive contact of bearing pads. Background technique [0002] As the key component of the sliding bearing, the bearing bush rotates with the journal surface during the working process. Form a lubricating film between the friction pairs by means of oil lubrication, etc., so as to achieve the purpose of drag reduction and wear resistance, and are widely used in power equipment such as diesel engines. [0003] In order to meet the needs of social development, bearing bushes are facing increasingly severe working conditions such as high temperature, high speed and high pressure. Especially in the start-up stage of the equipment, many problems arise immediately, such as insufficient lubricant supply and excessive impurities, which may lead to failure phenomena such as gluing and other direct contact between the ...
