Background technology
The measuring method of cylinder roller bearing solid cage pocket is to go measurement using feeler gauge, and feeler gauge measurement can only judge
Whether pocket bore dia scope is qualified, and can not read its measured value.When surveying the centre of gyration of retainer, retainer pocket hole is in
Heart footpath is symmetrical（Double deciles）Or oblique center-diameter（Single decile）Entity measuring cylindrical roller, measurement cylinder rolling are put into the pocket hole of position
Sub- diameter is equal to retainer pocket hole minimum diameter, and when processing retainer pocket hole, retainer pocket bore dia is all processed into pocket hole most
Major diameter, retainer pocket hole maximum gauge and retainer pocket hole minimum diameter difference measure cylindrical roller between 0.2mm ~ 0.4mm
There is certain gap with retainer pocket bore dia.Gap it is in different size, the numerical error measured is larger, cause measurement
The retainer centre of gyration footpath gone out is inaccurate, larger with technological design dimensional discrepancy, after bearing assembling, influence bearing revolution.
The content of the invention
For the defect of prior art, the purpose of this utility model is disclosed in a kind of cylinder roller bearing solid cage
Heart footpath measures sample post.Sample post of the present utility model can accurately, quick, easy, measurement retainer centre of gyration footpath technique chi
It is very little.
The technical solution of the utility model is：
A kind of cylinder roller bearing solid cage center-diameter measures sample post, sample post by the first cone, the first cylinder,
Second cone, the second cylinder, five sections of the 3rd cylinder connect composition, and the first cone is used as top, and the 3rd cylinder is made
For bottom, two long recess are opened in the monosymmetric axial direction to sample post of radial centre lines on the first cone top, it is two long
Groove groove depth is extended at the grinding undercut of the second cylinder；The first cylinder top end of sample post is extended to from the bottom of sample post
Place, opens a blind cylindrical hole.
Described two long recess groove depths of sample post are at the second cylinder grinding undercut.
The blind cylindrical hole diameter is than the small 8mm of retainer pocket bore dia to be measured.
The total height of the cone of sample post first and the first cylinder is equal to retainer pocket depth to be measured.
The 3rd cylinder outside dimension is the maximum process in retainer pocket hole to be measured.
The first cylinder external diameter is more than retainer pocket hole process 0.2-0.4mm to be measured.
The excessive angle α of first cone is 30 °.
The excessive angle beta of second cone is 45 °.
The sample post material uses W18Cr4V, and thermally treated hardness reaches HRC43-48.
Sample post of the present utility model measures cylinder roller bearing solid cage center-diameter, and the numerical value measured is precisely, stable,
The stability of retainer product is ensure that, product quality is improved.

Embodiment
The utility model is illustrated with reference to accompanying drawing 1.
A kind of cylinder roller bearing solid cage center-diameter measures sample post, and sample post is by the first cone 1, the first cylinder
2nd, the second cone 3, the second cylinder 4,5 five sections of the 3rd cylinder connect composition, and the first cone 1 is used as top, the 3rd circle
Cylinder 5 opens two long recess in the monosymmetric axial direction to sample post of radial centre lines as bottom on the top of the first cone 1
6, two groove depths of long recess 6 are extended at the grinding undercut 7 of the second cylinder；The first circle of sample post is extended to from sample column bottom
The top end of cylinder 1, opens a blind cylindrical hole 9.
Two groove depths of long recess 6 of sample post are at the grinding undercut 7 of the second cylinder 4.
The diameter of blind cylindrical hole 9 is than the small 8mm of retainer pocket bore dia to be measured.
The total height of sample post the first cone 1 and the first cylinder 2 is equal to retainer pocket depth to be measured.
The outside dimension of 3rd cylinder 5 is the maximum process in retainer pocket hole to be measured.
The external diameter of first cylinder 2 is than the big 0.2-0.4mm of retainer pocket hole process to be measured.
The excessive angle α of first cone 1 is 30 °.
The excessive angle beta of second cone 3 is 45 °.
Sample post material uses W18Cr4V, and thermally treated hardness reaches HRC43-48.
Cylinder roller bearing solid cage center-diameter measures the application method of sample post, is according to retainer to be measured first
Process, first processes several sample posts.2 sample posts are taken, what retainer diametrically claimed are inserted in 2 sample column tops respectively
In two pocket holes, sample top end is set to be directed at the axial centre of retainer by the center section 8 that two long recess 6 are separated out, and make 2
Individual sample top end keeps radial level by the center section 8 that two long recess are separated out, and the part of the first cylinder of sample post 2 is used as master
Measuring point is wanted, its diameter is extruded than the retainer pocket hole big 0.2-0.4mm of process, sample post by retainer pocket hole inner circle
Power, the direction of extruding force is the axle center for being directed radially towards sample post, and when sample post is acted in radial direction by symmetric force, sample post can occur
Elastic deformation, in retainer pocket bore dia process dimensional change, the external diameter of retainer pocket hole inwall and the cylinder of sample post first
It is closely against together so that very close to each other between sample post and retainer pocket hole, recycles slide calliper rule to block 2 sample posts, measures 2 samples
The circumscribed circular diameter of post, measured numerical value subtracts a sample column diameter, and institute's value is retainer centre of gyration footpath technique
Size.
Sample post measured value of the present utility model is accurate, stable, it is ensured that the stability of retainer product.
