An oil-proof, water-proof and dust-proof bearing protector

Abstract

The invention relates to an oilproof, waterproof and dustproof bearing protector. The oilproof, waterproof and dustproof bearing protector is composed of a bearing protector base and a waterproof and dustproof ring which are sequentially installed on a shaft; the inner end face of the waterproof and dustproof ring makes contact with the step face arranged on the bearing protector base; an inner cavity of the bearing protector base is a J-shaped collecting cavity; a lubricating oil collecting tank is formed in the bottom of the J-shaped collecting cavity; a maze sealing structure is adopted for the contact face between the bearing protector base and the shaft; a maze seal is communicated with a conical oil returning tank through a sealing flow channel; the waterproof and dustproof ring and the shaft form fixed sealing through a transmission sealing ring and a shaft; two annular grooves are machined in the outer circle of the waterproof and dustproof ring towards the inner side and are in clearance fit with the bearing protector base; and a gasp is communicated with a water returning tank. The oilproof, waterproof and dustproof bearing protector prevents outward leakage of lubricating oil, prevents rainwater and dust from entering a bearing, and guarantees that the bearing runs reliably for a long time.

Description

technical field [0001] The invention belongs to the technical field of bearing protectors, in particular to an oil-proof, waterproof and dust-proof bearing protector. Background technique [0002] At present, there are common problems of oil leakage and water leakage in the bearing box and other leakage problems in the use of pumps. Oil leakage will cause the loss of lubricating oil and pollute the environment of the equipment; water entering the lubricating oil will emulsify the lubricating oil and rapidly oxidize and deteriorate, not only losing the lubricating effect, but also corroding the bearing and equipment; and solid particles infiltrating into the moving parts If the mating surface is damaged, it will accelerate the wear of the surface of the parts and greatly shorten the service life of the pump. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an oil-proof, waterproof and dust...
