Polymer thrust bearing and preparation method thereof

The invention discloses a polymer thrust bearing and a preparation method thereof. The preparation method comprises following procedures: (1) the polymer thrust bearing is provided, and grooves are formed in optimized measurement points of the bush back of the polymer thrust bearing; (2) an ultrasonic piezoelectric element is provided as an ultrasonic sensor, and piezoelectric elements are installed on optimized measurement points of the back of a bearing bush; and (3) one end of a coaxial cable is welded to the positive and negative poles of the piezoelectric element, and the piezoelectric elements, the coaxial cable, and the bearing bush are merged together to form an intelligent body. According to the polymer thrust bearing and the preparation method thereof, the multiple ultrasonic piezoelectric elements are embedded in the optimized measurement points in the back of the bearing bush under the premise of ensuring that the bearing structure and performance are not adversely affected, so that the polymer th
