The invention discloses a self-centering heat-proof thrust bearing housing structure for a submersible motor. The self-centering heat-proof thrust bearing housing structure comprises a base, wherein a bearing bush is fixedly arranged on the base, a plurality of cylindrical slide rolls are glidingly arranged on the bearing bush, a top disc sleeves the upper part of the bearing bush, the axis of each slide roll is parallel with a contact surface between the corresponding slide roll and the bearing bush, a bearing block is arranged at the outer side of each slide roll, and is glidingly clamped into a groove of the bearing bush, the connecting parts of the side wall, the top wall and the bottom wall of each slide roll are respectively provided with an inclined surface, two strip-shaped first coating layers are symmetrically arranged on a contact surface between the top disc and the side wall of each slide roll by using the axis of the corresponding slide roll as a symmetric axis, a second coating layer is arranged between the corresponding two first coating layers, rotary shafts are fixedly arranged at the two ends of each slide roll, and the two ends of each rotary shaft are respectively hinged to the same side ends of the adjacent rotary shafts by connecting rods. The invention also provides a manufacturing method of a thrust bearing housing. The self-centering heat-proof thrust bearing housing structure has the advantages that the defects of the prior art are overcome, and the bearing overheat is reduced.
Description
technical field [0001] The invention relates to the technical field of thrust bearings, in particular to a self-aligning heat-proof thrust bearing seat structure for a submersible motor and a manufacturing method thereof. Background technique [0002] Thrust bearing is a special bearing used to bear axial force, and is widely used in various motors. All the thrust bearings in the prior art have a self-aligning function, which can improve the running state of the motor. However, since the existing thrust bearings are aligned by the rigid extrusion friction between the bearing parts, the thrust bearing generates a large amount of heat, and the thrust bearing is easily overheated. In the prior art, different methods are used to improve the thrust bearing, and efforts are made to reduce the heat generation of the thrust bearing during operation. However, none of the prior art has changed the structure in which the thrust bearing is aligning through friction, and has not fundam...
