Technical field
The utility model is related to a kind of axle sleeve, more particularly to a kind of graphite bushing.
Background technology
Axle sleeve is the tubular machine components being sleeved in shaft, is a component part of sliding bearing, and axle sleeve is whole knot
Structure, relative motion between bearing and axle sleeve during rotation, and axle sleeve has good protective capability to bearing, and bearing is made not to be subject to
To destruction.
And existing axle sleeve is during longtime running, journal surface is by the extruding force of expansion set and composite machine power
Effect will lead to its permanent deformation, diameter or reduction 0.1mm~0.3mm, and then mechanical expansion tight fit dynamics is caused to be not achieved
It is required that tighten power, occur fit clearance between axle sleeve and main shaft, cause the abrasion of axle sleeve, leverage axle sleeve and bearing
Between active force, secondly existing axle sleeve do not have good self-protection ability, be relatively easy to be damaged, greatly contract
The service life of axle sleeve is subtracted, can not meet people's needs.For this purpose, a kind of it is proposed that graphite bushing.
Utility model content
The main purpose of the utility model is that a kind of graphite bushing is provided, and it is novel in design, it is simple in structure, have good
Self-lubricate and anti-rotten rust ability, make that between bearing and axle sleeve good operating can be obtained, secondly, axle sleeve has good
Self-protection ability phenomena such as being not susceptible to deform, damage, further increases the service life of axle sleeve, can effectively solve to carry on the back
The problems in scape technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of graphite bushing, including housing, the jacket internal is fixedly connected with graphite, and the graphite side is fixedly connected
There is graphite raised, the housing inner surface is fixed with shrinkage pool, and the shrinkage pool bottom end is fixed with decompression line, the housing appearance
Face is fixed with oil filler point.
Further, the housing top peripheral is fixedly connected with fixed seat, and the fixed seating face is fixed with fixation
Hole.
Further, the graphite protrusion is located inside shrinkage pool, and is fixedly connected with shrinkage pool, and the graphite projects through recessed
Hole is flushed with housing inner surface.
Further, the housing is the housing that copper metal makes.
Compared with prior art, the utility model has the advantages that：
1. this kind is used for a kind of graphite bushing, by the combination of fixed seat and mounting hole, convenient for staff's fixed hub,
Preventing bearing, there is displacement in axle sleeve in axle sleeve inner rotation, so as to influence the normal work of bearing.
2. by the combination of graphite and graphite protrusion, there is good high temperature resistance and corrosion resistance, axle sleeve is made not to be subject to
To damage, increase the service life of axle sleeve, and graphite protrusion is flushed with housing inner surface, when bearing is in axle sleeve inner rotation,
It can play the role of between axle sleeve and bearing self-lubricated, bearing is made to be not easy to damage, increases the working efficiency of bearing.
3. good protective capability can be played to axle sleeve by housing, axle sleeve is made not to be subject to destroy, and housing is copper
Metal makes, and has good heat dissipation performance, the heat generated between bearing and axle sleeve is enable to be distributed in time, promotes axis
The practicability of set.
4. by depressurizing line with good depressurization, axle sleeve is prevented after the mechanical force of bearing is subjected to for a long time, is occurred
Phenomena such as deformation or enlarged-diameter, so as to influence the active force between axle sleeve and bearing.

Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
As shown in Figs. 1-2, a kind of graphite bushing including housing 1, is fixedly connected with graphite 2 inside the housing 1, described
2 side of graphite is fixedly connected with graphite protrusion 3, and 1 inner surface of housing is fixed with shrinkage pool 4, and 4 bottom end of shrinkage pool is fixed and set
There is decompression line 5,1 outer surface of housing is fixed with oil filler point 6.
Wherein, 1 top peripheral of housing is fixedly connected with fixed seat 7, and 7 surface of fixed seat is fixed with mounting hole
8。
Wherein, the graphite protrusion 3 is located inside shrinkage pool 4, and be fixedly connected with shrinkage pool 4, and the graphite protrusion 3 is by recessed
Hole 4 is flushed with 1 inner surface of housing.
Wherein, the housing 1 is the housing that copper metal makes.
It should be noted that the utility model is a kind of graphite bushing, during work, pass through fixed seat 7 and the knot of mounting hole 8
It closes, convenient for staff's fixed hub, preventing bearing, displacement occurs in axle sleeve, so as to influence bearing in axle sleeve inner rotation
Normal work, secondly, by the combination of graphite 2 and graphite protrusion 3, there is good high temperature resistance and corrosion resistance, make axis
Set is not easy to be damaged, and increases the service life of axle sleeve, and graphite protrusion 3 is flushed with 1 inner surface of housing, in bearing in axle sleeve
It when portion rotates, can play the role of between axle sleeve and bearing self-lubricated, bearing is made to be not easy to damage, increases the work of bearing
Efficiency can play axle sleeve good protective capability by housing 1, axle sleeve is made not to be subject to destroy, and housing 1 is copper metal
It makes, there is good heat dissipation performance, the heat generated between bearing and axle sleeve is enable to be distributed in time, promotes axle sleeve
Practicability by depressurizing line 5, has good depressurization, prevents axle sleeve from becoming after the mechanical force of bearing is subjected to for a long time
Phenomena such as shape or enlarged-diameter, so as to influence the active force between axle sleeve and bearing, secondly, by oil filler point 6, convenient for work
Personnel fill out the greasing substances such as lubricant to axle sleeve inner surface benefit, make so as to increase the lubrication between axle sleeve inner surface and bearing
With, and situations such as can effectively prevent from occurring between axle sleeve and bearing getting rusty, the practical performance of axle sleeve is further improved.
