Description
Technical field
It the utility model is related to a kind of bearing fixture.
Background technology
Bearing is one of important spare part in industrial production, is usually mounted to the both ends of axis, enables the shaft to rotate freely.
For bearing when in installation to axis, traditional mounting means is to need to tap bearing inner race, taps outer ring and is easily damaged bearing, still
Axis surface is often damaged when tapping inner ring, moreover, being installed by this kind of mode, bearing is easily tilted and dropped, difficult to install；If
Using special frock, then structure is often more complicated, and cost is higher.
Utility model content
The purpose of this utility model is that it is directed to drawbacks described above of the prior art, there is provided a kind of bearing folder easy for installation
Have, bearing will not be damaged in installation process.
To realize above-mentioned purpose of utility model, the utility model employs following technical solution：A kind of bearing fixture, it is wrapped
The mounting hole for accommodating the bearing is included, the mounting hole is provided with the protrusion abutted against with the bearing inner race, the bearing
Fixture is further opened with the avoid holes being coaxially disposed with the mounting hole.
In addition, the utility model also proposes following attached technical scheme：
The mounting hole includes bottom surface, and the protrusion is arranged on the bottom surface.
The mounting hole includes side wall, and the side wall is slightly larger than the outside diameter of the bearing.
The protrusion is annular shape.
The protrusion includes inner and outer wall, and the diameter of the inner wall is greater than or equal to the internal diameter of the bearing inner race.
The diameter of the outer wall is equal with the outside diameter of the bearing inner race.
The diameter of the avoid holes is equal to or more than the internal diameter of the protrusion.
The depth of the mounting hole is equal or slightly less than the thickness of the bearing with the bearing thickness.
Compared with the prior art, the utility model has the advantage of：The bearing clamp structure of the utility model is simple, bearing
It is easy for installation, and the surface of bearing and axis will not be damaged in installation process.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model bearing fixture.
Fig. 2 is the use schematic diagram of the utility model bearing fixture.
Embodiment
Technical solutions of the utility model are made below in conjunction with preferred embodiment and its attached drawing further nonrestrictive detailed
Explanation.
As shown in Figure 1 to Figure 2, corresponding to a kind of better embodiment of the utility model bearing fixture, during it is substantially in
Empty cylindrical shape, centre offer the avoid holes 5 of the end 11 for avoiding axis 9, offer and be used in the upper end of bearing fixture
The mounting hole 2 of bearing 1 is placed, mounting hole 2 is identical with the axis of avoid holes 5.The side wall 6 of mounting hole 2 is outer slightly larger than bearing 1
Footpath, the depth of mounting hole 2 is preferably equal with 1 thickness of bearing or is slightly less than the bearing thickness, bearing 1 is put into installation
In hole 2 and positioned.The protrusion 4 abutted against with 1 inner ring 1b of bearing is provided with the bottom surface 3 of mounting hole 2, protrusion 4 is in
Annular shape, including inner wall 7 and outer wall 8, the diameter of inner wall 7 are identical or more than inner ring 1b with the internal diameter of the inner ring 1b of bearing 1
Internal diameter, the diameter of outer wall 8 are identical with the outside diameter of the inner ring 1b of bearing 1.Avoid holes 5 are preferably identical with 7 diameter of inner wall.
During using this bearing fixture, first bearing 1 is put into mounting hole 2, then erects the end 11 for the axis 9 for needing to assemble
Directly it is aligned and props up the internal diameter of 1 inner ring 1b of bearing, tap the tail end 10 of axis 9 afterwards, end 11 is loaded 1 inner ring of bearing.Due to
The inner ring 1b of bearing 1 is raised portion 4 and props up, therefore is always 1 inner ring 1b stress of bearing in assembling process, will not damage bearing
1, the surface of axis will not be damaged by tapping tail end 10.Axis 9 is proposed after assembling.
The bearing clamp structure of the utility model is simple, and bearing is easy for installation, and bearing will not be damaged in installation process
With the surface of axis.
It is pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, its purpose
The content that is to allow person skilled in the art to understand the utility model is simultaneously implemented according to this, can not limit this reality with this
With new protection domain.All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in this reality
Within new protection domain.
