Abstract
The utility model discloses a kind of split bush, including sleeve body, axis hole is provided with sleeve body, opening is provided with sleeve body, opening includes the first open section, the second open section and the 3rd open section being sequentially connected, and the first open section and the 3rd open section are parallel, the radial direction of first open section and sleeve body tilts, set fluted on the inwall of axis hole, the length of groove is equal to the length of sleeve body, and the width of groove is in being gradually incremented by.Axle sleeve of the present utility model, by the design of opening and groove, caused heat in rotating shaft and axle sleeve friction process can be effectively discharged, avoids causing rotating shaft or bearing infringement because temperature is too high, it is easy to the addition of lubricating oil simultaneously, extends the service life of the parts such as axle sleeve, rotating shaft and bearing.
Description
Technical field
It the utility model is related to mechanical fitting technical field, and in particular to a kind of split bush.
Background technology
In moving component, the abrasion of part is caused because of long-term abrasion, when axle and the gap wear in hole are to certain
Just necessary renewal part, therefore use the abrasion of axle sleeve can reduction axle and bearing when degree.Axle sleeve also plays fixation
The centralized positioning of axle and bearing, it is not allowed to be shifted over because of being shaken when operating.Existing axle sleeve can not effectively discharge
Caused heat in rotating shaft and axle sleeve friction process, and cause axle or bearing infringement, influence the normal operation of transmission mechanism.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of split bush, can effectively discharge rotating shaft and axle sleeve rubs
Caused heat during wiping, avoid causing rotating shaft or bearing infringement because temperature is too high, while be easy to adding for lubricating oil
Add, extend the service life of the parts such as axle sleeve, rotating shaft and bearing.
In order to solve the above-mentioned technical problem, the technical scheme that the utility model is provided is as follows：
A kind of split bush, including sleeve body, axis hole is provided with the sleeve body, is set on the sleeve body
There is opening, the opening includes the first open section, the second open section and the 3rd open section being sequentially connected, first open section
Parallel with the 3rd open section, the radial direction of first open section and the sleeve body tilts, on the inwall of the axis hole
Set fluted, the length of the groove is equal to the length of the sleeve body, and the width of the groove is in being gradually incremented by.
It is 90 °~180 ° that first open section is angled with second open section.
The angle angle that the radial direction of first open section and the sleeve body tilts is 30 °~60 °.
Multiple grooves are provided with the shaft hole inner wall.
The depth of the groove is less than 2/3rds of the sleeve body wall thickness.
The inner surface setting of the axis hole has wear-resistant coating.
The wear-resistant coating is ceramic layer.
The thickness of the wear-resistant coating is 50~100 μm.
The utility model has the advantages that：Axle sleeve of the present utility model, can by the design of opening and groove
Effectively caused heat in release rotating shaft and axle sleeve friction process, avoid causing rotating shaft or bearing damage because temperature is too high
Evil, while it is easy to the addition of lubricating oil, extend the service life of the parts such as axle sleeve, rotating shaft and bearing；Overall structure is simple, weight
Amount is light, and fatigue resistance is high.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model；
Fig. 2 is main structure diagram of the present utility model；
In figure：1st, sleeve body, 2, axis hole, 21, groove, 3, opening, the 31, first open section, the 32, second open section, 33,
3rd open section.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As shown in figure 1, a kind of split bush, including sleeve body 1, axis hole 2 is provided with sleeve body 1, is used in axis hole 2
In being provided with opening 3 in installation rotating shaft, sleeve body 1, opening 3 includes the first open section 31, the second open section being sequentially connected
32 and the 3rd open section 33, the first open section 31 and the 3rd open section 33 are parallel, the footpath of the first open section 31 and sleeve body 1
To tilting, it is possible to understand that, as shown in Fig. 2 the inwall for defining the plane of symmetry of the first open section 31 and sleeve body 1 is (or outer
Wall) the plane that forms of axis of intersection and sleeve body 1 be the first plane, then the footpath of the first open section 31 and sleeve body 1
To tilting, i.e., the plane of symmetry of the first open section 31 tilts with the first plane, and the angle for tilting composition is α；
Fluted 21 are set on the inwall of axis hole 2, the length of groove 21 is equal to the length of sleeve body 1, the width of groove 2
In gradually incrementally, the design of groove 21 is easy to so that dust is discharged in rotating shaft rotary course along the length direction of groove 21, avoid
Dirt accumulation influences pivot on the inwall of axis hole, while groove 21 also can just store lubricating oil, make lubricating oil preferably
Lubricate rotating shaft.
Axle sleeve of the present utility model, by the design of opening 3 and groove 21, the addition for lubricating oil of being more convenient for, and can have
Caused heat in effect release rotating shaft and axle sleeve friction process, avoid causing rotating shaft or bearing infringement because temperature is too high,
Extend the service life of the parts such as axle sleeve, rotating shaft and bearing；Overall structure is simple, lighter in weight, and fatigue resistance is high.
Further, it is 90 °~180 ° that the first open section 31 is angled with the institute of the second open section 32.
Further, as shown in Fig. 2 the angle α that tilts of the radial direction of the first open section 31 and sleeve body 1 for 30 °~
60°。
Further, multiple grooves 21 are provided with the inwall of axis hole 2, more preferably to play dust discharge and lubrication.
Further, the depth of groove 21 is less than 2/3rds of the wall thickness of sleeve body 1.
Further, the inner surface setting of axis hole 2 has wear-resistant coating, to increase the wearability of the inwall of axis hole 2.
Further, wear-resistant coating is ceramic layer, and the thickness of wear-resistant coating is 50~100 μm, to reach preferably wear-resisting
Effect.
Embodiment described above is only the preferred embodiment to absolutely prove the utility model and being lifted, the utility model
Protection domain not limited to this.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
Change, within the scope of protection of the utility model.The scope of protection of the utility model is defined by claims.
