CN2874086Y - Bearing part oil seal structure for preventing thin oil lubrication leakage - Google Patents

Abstract

The utility model relates to an oil seal structure for bearing components that prevents leakage in thin-oil lubrication. The utility model comprises a bearing body, a bearing end cover, a bearing sleeve, an anti-dust disk, a bearing, a shaft, an oil slinger, and an oil returning hole. The utility model is characterized in that an oil retainer ring is provided on the shaft sleeve at the inside of the bearing end cover and the clearance of the bearing. The utility model can prevent leakage of thin lube along the bearing sleeve and the bearing end cover clearance, so as to improve reliability of a water pump, reduce use cost and protect the environment.

Description

A kind of bearing part oil seal structure that prevents that thin oil lubricant from leaking

Technical field

The utility model relates to a kind of oil seal structure, particularly a kind of bearing part oil seal structure that prevents that thin oil lubricant from leaking.

Background technique

The bearing fixing of existing water pump bearing parts is in the middle of axle sleeve and bearing support, lubricant oil is submerged under the bearing near the ball center line, the lubricant oil plane is lower than water pump face under the bearing (ball) cover, process two labyrinth sealing grooves on the bearing (ball) cover, bearing housing rotates with bearing, bearing (ball) cover is fixed on the bearing support, disc is thrown to rare lubricant oil on the bearing and is lubricated when relying on the water pump rotor parts to rotate, but there is following shortcoming in it: because bearing (ball) cover and bearing housing relative movement oil level face are lower than the bearing (ball) cover lower horizontal plane, so original technology is processed into labyrinth seal structure on bearing (ball) cover, when the water pump rotor parts rotate, because lubricant oil has certain viscosity, lubricant oil can be along the bearing housing horizontal motion, spill from bearing housing and bearing (ball) cover gap, must in time replenish the lubricant oil in the bearing support, the cost of labor of artificial increase.If make-up oil is untimely, can cause lubricant oil withered, bearing can not get good lubricating, and damages bearing.Lubricated is the chemical industry series products, and the leakage of lubricant oil pollutes the environment.

Summary of the invention

The purpose of this utility model is to solve in the prior art with the problem of the existing rare lubricant oil of rare oil lubrication water pump bearing parts along bearing housing and bearing (ball) cover clearance leakage, and a kind of bearing part oil seal structure that prevents the thin oil lubricant leakage is provided.A kind of bearing part oil seal structure that prevents that thin oil lubricant from leaking of the utility model design, comprise bearing support, bearing (ball) cover, bearing housing, dustproof dish, bearing, axle, disc, spill port, it is characterized in that: on the axle sleeve of the gap location of and bearing inboard a flinger ring is arranged at bearing (ball) cover.The utility model has the advantages that to make to prevent rare lubricant oil that reaching increases water pump reliability, reduction user cost, protection environment requirement along bearing housing and bearing (ball) cover clearance leakage.

Below in conjunction with drawings and Examples the utility model is elaborated,

Accompanying drawing is a structural representation of the present utility model,

Embodiment

Comprise bearing support 1, bearing (ball) cover 2, bearing housing 3, dustproof dish 4, bearing 5, axle 6, disc 7, spill port 8 among the figure, it is characterized in that: on the axle sleeve 3 of the gap location of and bearing 5 inboard a flinger ring 9 is arranged at bearing (ball) cover 2.A flinger ring 9 that increases in use motive sealing as at bearing housing 3 places, when axle 6 is static, since lubricated oil level be lower than bearing (ball) cover 2 below, so can not reveal by lubricant oil, in the time of axle 6 rotations, the lubricant oil that has been got rid of by disc 7 moves toward bearing (ball) cover 2 places from bearing 5, when running into flinger ring 9, flinger ring 9 with axle 6 high speed rotating produces centrifugal force, when outwards the lubricant movement of leakage arrives flinger ring 9 positions along bearing housing 3, because the reason of centrifugal force, can be along the radial motion of flinger ring 9, get back in the bearing support 1, can outwards not move, form motive sealing along bearing housing 3.

Claims (1)

1, a kind of bearing part oil seal structure that prevents that thin oil lubricant from leaking, comprise bearing support, bearing (ball) cover, bearing housing, dustproof dish, bearing, axle, disc, spill port, it is characterized in that: on the axle sleeve of the gap location of and bearing inboard a flinger ring is arranged at bearing (ball) cover.
