Problems solved by technology
[0002] At present, the high-load thrust bearings used in domestic submersible electric pumps are almost all imported. This is mainly due to the difficulty in bonding between the fan-shaped bearing pads on the thrust bearings and special engineering plastics. Fit as figure 1 As shown, a copper layer 5 is first pressed on the surface of the metal bearing pad, and then special engineering plastics are pressed on the copper to make them bond to each other; If it is produced by bonding, it is difficult to control the quality and production cost of the product

Embodiment Construction
[0034] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0035] A high-load thrust bearing provided by the present invention includes a hollow disc-shaped bearing seat body 1 made of 2CR13 stainless steel and a plurality of fan-shaped bearing pads 2, and the plurality of fan-shaped bearing pads 2 are arranged along the bearing seat. The body is movable at intervals in the circumferential direction on one surface of the bearing block body 1; on a surface of each bearing pad 2 facing away from the bearing block body 1, there is also integrally formed a protrusion protruding from the bearing pad block. The boss 20 on the surface, and the outer peripheral surface of each boss 20 is coated with a cladding layer 3 made of PEEK special engineering plastics, and the cladding layer 3 extends to the surface of each bearing pad perimeter.
[0036] Preferably, the pair of sector-shaped bearing pads 2 are symmetrically ...

The invention discloses a high-loading thrust bearing which comprises a hollow disc-shaped bearing seat body and a plurality of sector-shaped bearing tile blocks, wherein the plurality of sector-shaped bearing tile blocks are movably arranged on one surface of the bearing seat body at intervals along the circumference of the bearing seat body; a boss which protrudes out of the surface of the bearing tile block is integrally formed on one surface of each bearing tile block opposite to the bearing seat body; a wrapping layer made of special engineering plastic is wrapped on the outer circumference of each boss; and the wrapping layer extends to the circumference of the surface of each bearing tile block. Therefore, the wrapping layer can be well wrapped on the bearing tile block, so that the product quality of the thrust bearing is effectively improved.
Description
technical field [0001] The invention relates to the technical field of bearings used in electric submersible pumps, and specifically provides a high-load thrust bearing and a preparation process thereof. Background technique [0002] At present, the high-load thrust bearings used in domestic submersible electric pumps are almost all imported. This is mainly due to the difficulty in bonding between the fan-shaped bearing pads on the thrust bearings and special engineering plastics. Fit as figure 1 As shown, a copper layer 5 is first pressed on the surface of the metal bearing pad, and then special engineering plastics are pressed on the copper to make them bond to each other; If it is produced by bonding, it is difficult to control the quality and production cost of the product. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a high-load thrust bearing and its preparation process. The preparation process ...
