Abstract
The invention relates to a method for grinding conical raceways of bearing races. The method includes steps that workpieces are clamped on headstocks of internal circular grinding machines by the aid of fixtures at first, grinding wheels and the bearing races are respectively started to rotate, the workpieces are sequentially coarsely ground and accurately ground, the grinding wheels continuously or intermittently carry out transverse feeding movement towards the workpieces at slow speeds until all allowance is completely ground, and the axis of each grinding wheel and the axis of the corresponding workpiece need to be positioned on the same horizontal plane when the workpiece is coarsely ground and accurately ground; the grinding wheels are mounted on grinding heads of the internal circular grinding machines when working end surfaces of the grinding wheels need to be trimmed, and the working end surfaces of the grinding wheels are trimmed by movable grinding wheel trimmers to obtain conical surfaces with the angles of 85-88 degrees. The method for grinding the conical raceways of the bearing races has the advantages that the method is implemented by the aid of the grinding machines which are commonly utilized in the bearing manufacturing industry, accordingly, adjusting links are few, the grinding efficiency is high, high-speed grinding and automatic production are easy to implement, and the ground conical raceways of the bearing races are perfect in geometric accuracy and surface roughness.
Description
Technical field
The present invention relates to a kind of method for grinding of bearing race cone angle raceway.
Background technology
The seat ring raceway of auger angle bearing is the auger edged surface with taper or arc flange, in the time of the conical surface raceway of ground races, because the rib of seat ring is interfered the periphery grinding that can not use cylinder grinding wheel, add man-hour by the end face crush grinding of flaring cup wheel, after seat ring ball race grinding, geometry is arc surface, instead of the conical surface.How the conical surface raceway of the large cone angle seat ring of grinding bearing, makes can reach correct geometric accuracy after its grinding, and being needs the problem inquired into.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of method for grinding of bearing race cone angle raceway.
The method for grinding of described a kind of bearing race cone angle raceway, it is characterized in that comprising the steps: first on the headstock of internal grinder, by fixture, workpiece being clamped, then start respectively emery wheel and bearing race rotation, then roughly grind successively and refine, when grinding, workpiece is not done longitudinal reciprocating motion, emery wheel is done in-movement to workpiece continuously or interruptedly with speed slowly, until polish whole surpluses, in the time roughly grinding, the transverse reciprocating speed of emery wheel when the transverse reciprocating speed of described emery wheel is less than fine grinding; In the time roughly grinding and refine, the axis of described emery wheel and the axis of workpiece must be in same levels; When described emery wheel needs finishing process end face, emery wheel is arranged on the bistrique of internal grinder, adopts portable grinding wheel trimmer the operative end surface of emery wheel to be repaired out to the taper seat of 85-88 degree.
The method for grinding of described a kind of bearing race cone angle raceway, it is characterized in that the conical surface width of cone angle raceway is 30-100mm described in the grinding, when corase grind, the transverse reciprocating speed of emery wheel is 8-20 time/min, the 20-40 time/min of transverse reciprocating speed of emery wheel when fine grinding.
The method for grinding of described a kind of bearing race cone angle raceway, is characterized in that described emery wheel is thin-wall tube-shaped emery wheel, and the width of the operative end surface of emery wheel is the 1/4-1/8 of the conical surface width of cone angle raceway.
The method for grinding of the cone angle raceway of bearing race of the present invention, the grinding machine that adopts bearing manufacturing generally to adopt, adjustment link is few, and grinding efficiency is high, be easy to realize high-speed grinding and automated production, after grinding, the geometric accuracy of seat ring conical surface raceway and surface roughness are all more satisfactory.
