Abstract
The invention relates to a bearing inner ring. The bearing inner ring is characterized in that an annular dovetail groove is formed in the inner surface of an inner ring main body; a plurality of positioning holes are formed in a side surface of the inner ring main body; the axis directions of the positioning holes are consistent to the axis direction of the bearing inner ring; the positioning holes communicate with the dovetail groove; and positioning pins are arranged in the positioning holes. According to the technical scheme, when a shaft required to be clamped is a cube or is smaller than the bearing inner ring, sliding blocks are placed in block inlet grooves, and then enter the dovetail groove through the block inlet grooves, and after clamping blocks slide to desired places, the positioning pins are inserted in the positioning holes, and then are inserted in limiting holes of convex blocks, so that the clamping blocks are fixed on the inner ring main body; and at least two clamping blocks are mounted on the inner ring main body, therefore, the size of the bearing inner ring is changed, and the shaft can be locked.
Description
Technical field
The present invention relates to a kind of bearing inner ring.
Background technology
Development along with modern science and technology, bearing plays a very important role in our commercial production, due to its simple in construction, convenient for production, therefore very universal used in our production, can the size of bearing inner ring in the market fix, when the shapes and sizes of axle change, we must change corresponding bearing, uses inconvenience very.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide the technical scheme of a kind of bearing inner ring.
Described a kind of bearing inner ring, including internal ring main body, internal ring main body is provided with groove, it is characterized in that the inner surface of described internal ring main body is provided with annular dovetail slot, the side of described internal ring main body is provided with several holes, location, the axis direction in described hole, location is consistent with the axis direction of bearing inner ring, described hole, location communicates with dovetail groove, it is provided with alignment pin in described hole, location, the inner side of described internal ring main body is provided with fixture block, one end face of described fixture block is provided with the slide block corresponding with dovetail groove, described slide block can slide in dovetail groove, described slide block is provided with the spacing hole corresponding with alignment pin, the inner side of described internal ring main body is provided with corresponding with slide block enters block groove, the described block groove that enters communicates with dovetail groove, described internal ring body outer surface is provided with wear-resistant coating.
Described bearing inner ring, it is characterised in that one end of described fixture block opposing slider is toothed surfaces.
Described bearing inner ring, it is characterised in that the quantity of described fixture block is four.
Described bearing inner ring, it is characterised in that the quantity in hole, described location is ten and uniform circular is distributed on the side of internal ring main body.
Described bearing inner ring, it is characterised in that described bearing inner ring outer surface scribbles polyimide wear-resistant coating.
The present invention is by using technique scheme, when axle to be clamped be square or less than bearing inner ring time, by slide block being loaded into block groove, again by entering in block groove entrance dovetail groove, slip fixture block is to the place wanted, then alignment pin is inserted hole, location, it is inserted in the spacing hole on projection, thus realize being fixed in internal ring main body fixture block, internal ring main body at least loads two fixture blocks, thus the size of the bearing inner ring changed, and then can realize blocking axle, when the size of axle and the size of bearing inner ring body are suitable, only need to take out alignment pin, slip fixture block, the slide block being connected with fixture block is made to enter into block groove, again by entering block groove out, so pass sequentially through and take out fixture block into block groove, just can realize blocking the axle suitable with internal ring body.
Accompanying drawing explanation
Fig. 1 is the sectional view of the bearing main body of bearing inner ring embodiment of the present invention；
Fig. 2 is the axonometric drawing of bearing inner ring embodiment of the present invention；
Fig. 3 is the front view of the fixture block of bearing inner ring embodiment of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
A kind of bearing inner ring, including internal ring main body 1, internal ring main body 1 is provided with groove 5, described internal ring main body 1
Inner surface be provided with annular dovetail slot 4, the side of described internal ring main body 1 is provided with several holes 2, location, and the axis direction in hole 2, described location is consistent with the axis direction of bearing inner ring, and described hole, location 2 communicates with dovetail groove 4, described hole, location
Being provided with alignment pin 9 in 2, the inner side of described internal ring main body 1 is provided with fixture block 7, an end face of described fixture block 7 be provided with
The slide block 6 of dovetail groove 4 correspondence, described slide block 6 can slide in dovetail groove 4, described slide block
null6 are provided with the spacing hole 8 corresponding with alignment pin 9，The inner side of described internal ring main body 1 is provided with corresponding with slide block 6 enters block groove 3，The described block groove 3 that enters communicates with dovetail groove 4，Described internal ring main body 1 outer surface is provided with wear-resistant coating，When axle to be clamped be square or less than bearing inner ring body 1 time，By slide block 6 is loaded into block groove 3，Enter in dovetail groove 4 by entering block groove 3 again，Slip fixture block 7 is to the place wanted，Then alignment pin 9 is inserted hole 2, location，In the spacing hole 8 being inserted on projection，Thus realize being fixed in internal ring main body 1 fixture block 7，Internal ring main body 1 at least loads two fixture blocks 7，Thus the size of the bearing inner ring changed，And then can realize blocking axle，When the size of axle and the size of bearing inner ring body 1 are suitable，Only need to take out alignment pin 9，Slip fixture block 7，The slide block 6 being connected with fixture block 7 is made to enter into block groove 3，Again by entering block groove 3 out，So pass sequentially through and take out fixture block 7 into block groove 3，Just can realize blocking and internal ring body
1 suitable axle.
One end of described fixture block 7 opposing slider 6 is toothed surfaces, it is possible to increase the friction that fixture block 7 contacts with axle, enables transducing and the most preferably blocks axle.
The quantity of described fixture block 7 is four, by loading four fixture blocks 7 on bearing inner ring, and the distribution of four fixture block 7 uniform circular, block axle at four direction, thus preferably clamping shaft.
The quantity in hole 2, described location is ten and uniform circular is distributed on the side of internal ring main body 1, can preferably block the axle of difformity and size.
Described internal ring main body 1 outer surface scribbles polyimide wear-resistant coating, improves thermostability, insulating properties and the anti-wear performance of internal ring main body 1 outer surface, improves the service life of bearing.
