Description
Technical field
The present invention relates to a kind of processing methods of the thin-walled of field of bearings more particularly to thin-wall bearing inner ring/outer ring.
Background technology
Currently, in the prior art, if bearing outside diameter is D, internal diameter d, radial section is sized at (D-d)/2.In general,
Radial section size is less than the 1/4 of internal diameter, or less than the 1/6 of outer diameter, or can less than twice of rolling bearing of rolling element diameter
To regard thin-walled antifriction bearings as.The weight of thin-wall bearing is typically less than the 1/2 of the ultralight series axis supporting power of same inner diameter, some
The weight of model thin-wall bearing is even less than the 1/40 of the ultralight series axis supporting power of same inner diameter, it is seen that thin, the width of its wall thickness
It is narrow.
The application scenario of thin-wall bearing is all more accurate, typical such as industrial robot harmonic speed reducer flexible bearing,
RV retarders bearing, robot waist and crotch's cross roller bearing, but the lasso wall thickness of thin-wall bearing is very thin, it is wide
Degree is very narrow, is all very easy to deformation in all links of working process, obtains the high accuracy of manufacture and be extremely not easy.
Existing thin-wall bearing manufacturing enterprise still uses the cutting of normal thickness bearing ring to add by taking flexible bearing as an example
Work technological process, only putting than more elegant and careful to lasso in the heat treatment process before machining, raceway groove is adopted
With 2 times or 2 times or more grinding formings, increases between corase grinding and precision grinding process and add tempering process, these measures are taken, no doubt
So that the accuracy of manufacture of lasso increases, but improves limitation, moreover, the use of these measures greatly reduces thin-walled
The manufacture efficiency of lasso improves thin-walled lasso and then improves the manufacturing cost of thin-wall bearing.It traces it to its cause and is exactly, covering
During the grinding of circle and superfinishing, lasso can be inevitably by magnetic adsorptive power, chucking power, support force from fixture
With the pressure from grinding wheel, oilstone, cutting force, under the action of these power, normal thickness lasso will not deform or deform pole
It is micro-, and thin-walled lasso especially flexible bearing lasso will occur significantly to deform.Thin-walled lasso is difficult to obtain high processing essence
Degree and the host required precision growing to thin-wall bearing form a pair of contradiction outstanding, seriously constrain lightweight master
Machine running accuracy and limit speed further increase, and invention is economically viable to increase substantially thin-wall bearing ferrule especially
The process of flexible bearing lasso machining accuracy and processing efficiency, it appears very urgent and necessary.
