Description
Technical field
The utility model is related to bearing lubrication technical field, more particularly to a kind of sealing mechanism of bearing, more particularly to
A kind of slide bearing assembly.
Background technology
Sliding bearing has the advantages that service life length, reliable is more and more widely used.Due to sliding axle
Hold inside and outside differential pressure greatly, generally using the bearing shell of forced feed lubrication, lubricating oil has certain pressure in itself, the oily meeting when axle runs at high speed
Bubble (the partly impact from disc to oil) is produced, so as to produce certain pressure, sliding bearing is operationally due to interior
The high speed rotation of portion's bearing shell so that Bearing inner has certain negative pressure with outside, and (internal pressure is big so as to increase grease chamber inside and outside differential pressure
In external pressure), cause oil leakage phenomenon.When therefore using the sliding bearing of forced feed lubrication, how to solve its oil leakage phenomenon is design work
Author's urgent problem.
The general sealing only with labyrinth of sealing of existing sliding bearing holder assembly, because the sealing property in labyrinth is relative
It is weaker, and because the cooperation of labyrinth and axle does not reach requirement, cause the transmission effect in labyrinth not good, not only cause entering for dust
Enter pedestal, also cause the loss of power.
The sealing for sliding bearing proposes several adjustment modes in the prior art, but all there are various problems：1、
A kind of sliding bearing holder assembly that CN201420421577.5 is provided, the sliding bearing holder assembly includes pedestal, bearing, axle, end
Lid, labyrinth, ring spring, rubber gasket, described bearing is arranged on pedestal endoporus, and described axle is arranged on brearing bore, institute
The end cap stated is arranged on pedestal two ends, and there is maze trough at described end cap two ends, and described labyrinth and the maze trough of end cap, which coordinate, pacifies
Dress, described rubber gasket is installed in the mating groove of labyrinth and end cap, and described ring spring inner ring coordinates with axle, described bullet
Circlip outer ring coordinates with labyrinth inner ring, and described ring spring is split ring, on the basis of the labyrinth sealing of cast iron
The design of open type ring spring is employed, the sealing effectiveness of sliding bearing is reached, but use this kind of sliding bearing holder assembly close
The bearing of envelope, because the labyrinth of cast iron is fixed, so must reserve than larger gap, it is to avoid seal assembly and rotor
Mill is touched, in practice, problems with is brought：If 1) seal clearance is excessive between labyrinth and rotating shaft, by ring spring not
Can effectively it be sealed；2) when a slot reservation is smaller, because the flexibility or other reasonses of rotary shaft can cause sealing
Component touches mill with axle, is prone to accidents, there is potential safety hazard；2nd, the sliding bearing leakproof that CN 201220375837.0 is provided
Oily positive seal structure, the bearing seal structure of the malleation is by between sliding bearing and axle, sequentially forming some connections
An actor's rendering of an operatic tune, by, more than the barotropic gas of the air pressure in environment and adjacent an actor's rendering of an operatic tune, being blocked toward input inside an actor's rendering of an operatic tune by barotropic gas
The flow of greasy dirt, so as to realize the sealing to bearing, but uses this kind of mode to realize the sealed mode to bearing, due to cunning
It is not the setting being fully sealed between dynamic bearing and axle, forms an actor's rendering of an operatic tune of connection in the situation by larger barotropic gas
Under, it is easier to the gap leakage between sliding bearing and axle, and positive gas generator external the need for this kind of bearing, take volume
Outer space could be realized.
Therefore, this also constitutes the sealing structure for requiring further improvement sliding bearing, particularly suitable rotating speed is higher, knot
The bearing seal of conformational space closely, with the problems of solution.
