Runner-plate pump self-lubricating radial thrust bearing

Abstract

The invention discloses a runner-plate pump self-lubricating radial thrust bearing. An electric pump is arranged outside a bearing seat; the oil inlet joint of the electric pump is connected with a cold oil outlet on the lower part of the bearing seat; the oil outlet of the electric pump is communicated with a first oil inlet of a three-way valve through a pipeline; the oil outlet joint of the three-way valve is connected with a cold oil inlet on the upper part of the bearing seat; the cold oil inlet is communicated with an annular oil inlet groove on the external circular plane of a radial bearing; and a first radial hole, a radial blind hole and an axial blind hole which are communicated with the annular oil inlet groove are formed on the radial bearing. Generated hot oil is delivered and cooled in time by centrifugal force which is generated when a thrust head rotates, and the cooled cold oil is continuously injected into the bearing to meet the requirement of the normal work of the bearing, so that self-lubrication can be realized, an oil-diluting lubricating device and a pressure pump are not required to be specially arranged as before, equipment is reduced, cost is lowered, space which is occupied by the oil-diluting lubricating device and the pressure pump is saved, and the runner-plate pump self-lubricating radial thrust bearing is convenient to arrange and has good lubricating and cooling effects, a skilful concept and a simple structure.

Description

technical field [0001] The invention belongs to the technical field of hydraulic generators, in particular to a self-lubricating radial thrust bearing of a mirror plate pump of a hydraulic generator. Background technique [0002] The traditional radial thrust bearing includes a bearing housing and a bearing cover. Thrust pads are evenly distributed along the circumferential direction on the right end surface of the radial pad. An inner cover is sheathed on the outside of the inner cover, and an outer cover is placed outside the inner cover, and the left end of the outer cover is fixedly connected with the right end of the bearing seat and the bearing cap through screws. Before and during the working process of the radial thrust bearing, it is necessary to continuously inject pressure lubricating oil into the bearing to lubricate the joint surface between the radial pad and the main shaft and the joint surface between the thrust head and the thrust pad to prevent Burning til...

AI Technical Summary

Problems solved by technology

In daily use, we found that traditional radial thrust bearings need to be specially equipped with thin oil lubrication devices and pressure pumps, which not only adds equipment, increases costs, but also occupies a large volume, which is not easy to arrange

In addition, the cold oil after lubricating the parts becomes hot oil, which needs to be cooled and cooled by the oil cooler. Traditional radial thrust bearings set the oil cooler inside the bearing seat, which leads to poor cooling effect of the hot oil. Therefore, , it is urgent to solve the above technical problems
