Description
Technical field
The present invention relates 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 axle, enables the shaft to rotate freely.
For bearing when being attached on axle, traditional mounting means is to need to tap bearing inner race, taps outer ring and is easily damaged bearing, still
Axle surface is often damaged when tapping inner ring, moreover, being installed by this kind of mode, bearing is easily tilted and dropped, installation difficulty；If
Using special frock, then structure is often more complicated, and cost is higher.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of bearing fixture easy for installation,
Bearing will not be damaged in installation process.
For achieving the above object, present invention employs following technical scheme：A kind of bearing fixture, it includes accommodating institute
The mounting hole of bearing is stated, the mounting hole is provided with the protuberance abutted against with the bearing inner race, and the bearing fixture is also opened
Provided with the avoid holes being coaxially disposed with the mounting hole.
In addition, the present invention also proposes following attached technical scheme：
The mounting hole includes bottom surface, and the protuberance is arranged on the bottom surface.
The mounting hole includes side wall, and the side wall is slightly larger than the external diameter of the bearing.
The protuberance is annular shape.
The protuberance includes inner and outer wall, and the diameter of the inwall is more than or equal to the internal diameter of the bearing inner race.
The diameter of the outer wall is equal with the external diameter of the bearing inner race.
The diameter of the avoid holes is equal to or more than the internal diameter of the protuberance.
The depth of the mounting hole is equal or slightly less than the thickness of the bearing with the bearing thickness.
Compared to prior art, the advantage of the invention is that：The bearing clamp structure of the present invention is simple, bearing installation side
Just, the surface of bearing and axle and in installation process will not be damaged.
Brief description of the drawings
Fig. 1 is the structural representation of bearing fixture of the present invention.
Fig. 2 is the use schematic diagram of bearing fixture of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in Figure 1 to Figure 2, corresponding to a kind of better embodiment of bearing fixture of the present invention, it is substantially in hollow
Cylindrical shape, centre offer the avoid holes 5 of the end 11 for avoiding axle 9, are offered in the upper end of bearing fixture for placing
The mounting hole 2 of bearing 1, mounting hole 2 are identical with the axis of avoid holes 5.The side wall 6 of mounting hole 2 is slightly larger than the external diameter of bearing 1, peace
The depth in dress hole 2 is preferably equal with the thickness of bearing 1 or is slightly less than the bearing thickness, bearing 1 is put into mounting hole 2
And positioned.The protuberance 4 abutted against with the inner ring 1b of bearing 1 is provided with the bottom surface 3 of mounting hole 2, protuberance 4 is in annulus
Shape, including inwall 7 and outer wall 8, the diameter of inwall 7 internal diameter identical or more than inner ring 1b with the inner ring 1b of bearing 1 internal diameter,
The diameter of outer wall 8 is identical with the inner ring 1b of bearing 1 external diameter.Avoid holes 5 are preferably identical with the diameter of inwall 7.
During using this bearing fixture, first bearing 1 is put into mounting hole 2, then erected the end 11 for the axle 9 for needing to assemble
Directly it is aligned and props up the inner ring 1b of bearing 1 internal diameter, tap the tail end 10 of axle 9 afterwards, end 11 is loaded the inner ring of bearing 1.Due to
The inner ring 1b of bearing 1 is raised portion 4 and propped up, therefore is always the inner ring 1b stress of bearing 1 in assembling process, will not damage bearing
1, the surface of axle will not also be damaged by tapping tail end 10.Axle 9 is proposed after assembling.
The bearing clamp structure of the present invention is simple, and bearing is easy for installation, and bearing and axle will not be damaged in installation process
Surface.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, it should all be included within the scope of the present invention.
