Description
Technical field
The utility model is related to the technical field of axle sleeve structure, especially a kind of self lubrication bearing.
Background technology
Axle sleeve is the tubular machine components being sleeved in shaft, is an important component of sliding bearing, axle sleeve is whole
Body structure, when rotation is relative motion between shaft and axle sleeve, and shaft is with axle sleeve also continuous during matching
Friction is carried out, ensures sufficient lubrication between the two by the way of adding lubricating oil between axle sleeve and shaft at present,
The further service life for extending axle sleeve and shaft.However, under non-stop-machine state, it is difficult to add between shaft and axle sleeve
Add lubricating oil.In order to solve this problem, usual people can open up the injecting structure of oil groove or lubricating oil on the inner wall of axle sleeve,
By having previously been stored in the lubricating oil in oil groove to supplementing new oil between shaft and axle sleeve, but the inner wall of axle sleeve at first by
Abrasion causes the increase of the gap of axle sleeve and shaft oil leakage phenomenon occur.Therefore there is an urgent need for a kind of axis that is wear-resistant, being capable of abundant repairing
Set.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, service life is long, resistance to
Lubricating oil, the self lubrication bearing with dust reduction capability are persistently mended in abrasion.
The purpose of this utility model is achieved through the following technical solutions：A kind of self lubrication bearing, it includes sleeve body,
The left and right end portions of the sleeve body offer stepped hole, and dustband, the sleeve body are both provided in two stepped holes
Multiple bar-shaped troughs are offered on the inner wall of axis hole and along its circumferencial direction, bar-shaped trough is axial arranged along sleeve body, bar-shaped trough
It is inside provided with spring and foam copper, spring is fixed on the bottom of bar-shaped trough, and foam copper is fixedly arranged on spring top.
The left and right end portions of the sleeve body are installed with left end cap and right end cap respectively.
The left end cap will be pressed on positioned at the dustband of sleeve body left part in stepped hole.
The right end cap will be pressed on positioned at the dustband of sleeve body right part in stepped hole.
Through-hole is offered in the right end cap and left end cap.
It is provided in the bar-shaped trough and along its length multiple springs.
The left end cap and right end cap are fixed on through screw on sleeve body.
The utility model has the following advantages：The utility model is compact-sized, service life is long, wear-resistant, lasting benefit profit
Lubricating oil has dust reduction capability.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A sectional views of Fig. 1；
In figure, 1- sleeve bodies, 2- stepped holes, 3- dustbands, 4- bar-shaped troughs, 5- springs, 6- foam coppers, 7- left end caps,
8- right end caps, 9- shafts.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1 and 2, a kind of self lubrication bearing, it includes sleeve body 1, and the left and right end portions of the sleeve body 1 are equal
Stepped hole 2 is offered, is both provided with dustband 3 in two stepped holes 2, on the inner wall of 1 axis hole of the sleeve body and along its circle
Circumferential direction offers multiple bar-shaped troughs 4, and bar-shaped trough 4 is axial arranged along sleeve body 1, and spring 5 and bubble are provided in bar-shaped trough 4
Foam copper 6, spring 5 are fixed on the bottom of bar-shaped trough 4, and foam copper 6 is fixedly arranged on 5 top of spring.
As shown in Figure 1, the left and right end portions of the sleeve body 1 are installed with left end cap 7 and right end cap 8, the present embodiment respectively
Described in left end cap 7 and right end cap 8 be fixed on sleeve body 1 through screw.Left end cap 7 will be located at 1 left part of sleeve body
Dustband 3 press in stepped hole 2, right end cap 8 will press on stepped hole 2 positioned at the dustband 3 of 1 right part of sleeve body
It is interior.The dustband 3 can prevent extraneous dust from entering in axis hole along shaft, protect shaft and axle sleeve well.
Through-hole is offered in the right end cap 8 and left end cap 7.It is provided in the bar-shaped trough 4 and along its length
Multiple springs 5.
The course of work of the utility model is as follows：Shaft 9 turned left from the right side and sequentially runs through the through-hole of right end cap 8, right side
The through-hole of dustband 3, the axis hole of sleeve body 1, left side dustband 3 and left end cap 7, to realize the installation of shaft 9；Under this state
Foam copper 6 is resisted against under the elastic force effect of spring 5 in shaft 9, and the lubricating oil viscosity on foam copper 6 realizes shaft in shaft 9
Lubrication.Shaft 9 is connect with motor, starts motor, motor drives shaft 9 to rotate, and in rotation process, shaft 9 is ground first
Foam copper 6 is damaged, rather than directly wears 1 inner wall of sleeve body, to protect axle sleeve well, extends the use of the axle sleeve
Service life has the characteristics that anti abrasive.After foam copper 6 is worn and generates gap with shaft 9, the foam under the effect of 5 elastic force of spring
Copper 6 continues to be resisted against in shaft 9, to persistently give lubricating oil in shaft 9, has the characteristics that compensate automatically, realizes lasting confession
Lubricating oil.
