Abstract
The invention discloses a transverse reciprocating grinding method for a cone angle raceway of a bearing race, which comprises the following steps: firstly, clamping a workpiece on a headstock of an inner circle grinder by a fixture; then respectively starting a grinding wheel and the bearing race to rotate; sequentially carrying out rough grinding and fine grinding; and in the grinding process, enabling the workpiece not to longitudinally reciprocate and enabling the grinding wheel to continuously or interruptedly carry out transverse feeding motion towards the workpiece at a low speed until polishing all allowance. When rough grinding is carried out, the transverse reciprocating speed of the grinding wheel is lower than that of the grinding wheel in the fine grinding process; and when rough grinding and fine grinding are carried out, the axis of the grinding wheel and the axis of the workpiece need to be on the same horizontal plane. According to the transverse reciprocating grinding method disclosed by the invention, grinding effect is better, production efficiency is high and the processing quality of the cone raceway is ensured.
Description
Technical field
The present invention relates to a kind of laterally reciprocal method for grinding of bearing race cone angle raceway.
Background technology
The seat ring raceway of auger angle bearing is the auger edged surface (Fig. 1) of band taper or arc flange.When 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 with flaring cup wheel end face crush grinding, geometry is arc surface after the grinding of seat ring raceway, rather than the conical surface.
The conical surface raceway of the big cone angle seat ring of grinding bearing how can reach correct geometric accuracy after making its grinding, and being needs the problem inquired into.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of laterally reciprocal method for grinding of bearing race cone angle raceway is provided, its ground effect is better, production efficiency height, the crudy of assurance conical surface raceway.
A kind of technical scheme that realizes above-mentioned purpose is: a kind of laterally reciprocal method for grinding of bearing race cone angle raceway, on the headstock of internal grinder, by anchor clamps workpiece is clamped earlier, then start the rotation of emery wheel and bearing race respectively, roughly grind successively then and finish grind, workpiece is not done vertical reciprocating motion during grinding, emery wheel is done in-movement to workpiece continuously or interruptedly with speed slowly, up to the whole surpluses of polishing, wherein:
When roughly grinding, the horizontal reciprocating speed of described emery wheel is less than the horizontal reciprocating speed of when correct grinding emery wheel;
When roughly grinding and finish grind, the axis of described emery wheel and the axis of workpiece must be on same horizontal planes.
The horizontal reciprocating type method for grinding of above-mentioned bearing race cone angle raceway, wherein, when the conical surface width of the described cone angle raceway of grinding is 30～100mm, the horizontal reciprocating speed of emery wheel is 8～20 times/min during corase grind, 20～40 times/min of horizontal reciprocating speed of emery wheel during correct grinding.
The horizontal reciprocating type method for grinding of above-mentioned bearing race cone angle raceway, wherein, described emery wheel is thin-wall tube-shaped emery wheel, the width of the operative end surface of emery wheel be the cone angle raceway conical surface width 1/4～1/8.
The technical scheme of the laterally back and forth method for grinding of bearing race cone angle raceway of the present invention adopts corase grind and correct grinding, and when roughly grinding, the horizontal reciprocating speed of the horizontal reciprocating speed of emery wheel emery wheel during less than correct grinding.In addition the width of the operative end surface of emery wheel is made as the cone angle raceway conical surface width 1/4～1/8, thereby make ground effect better, the production efficiency height guarantees the crudy of conical surface raceway.
The specific embodiment
In order to understand technical scheme of the present invention better, be described in detail below by specific embodiment:
The laterally reciprocal method for grinding of a kind of bearing race cone angle raceway of the present invention, on the headstock of internal grinder, by anchor clamps workpiece is clamped earlier, then start the rotation of emery wheel and bearing race respectively, workpiece is not done vertical reciprocating motion during grinding, emery wheel is done in-movement to workpiece continuously or interruptedly with speed slowly, roughly grind successively then and finish grind, up to the whole surpluses of polishing.
The horizontal reciprocating speed of emery wheel is answered choose reasonable, and when the horizontal reciprocating speed of general emery wheel increased, conical surface raceway face roughness descended, otherwise rose.The horizontal reciprocating speed that increases emery wheel has improved radiating condition to a certain extent.In order to guarantee the crudy of conical surface raceway, when corase grind, get less horizontal reciprocating speed, increase horizontal reciprocating speed when grinding eventually.
When the conical surface width of the cone angle raceway of grinding work piece is 30～100mm, method of the present invention is when roughly grinding, the horizontal reciprocating speed of emery wheel is less than the horizontal reciprocating speed of when correct grinding emery wheel, the horizontal reciprocating speed of emery wheel is 8～20 times/min when namely roughly grinding, 20～40 times/min of horizontal reciprocating speed of emery wheel during correct grinding.
When roughly grinding and finish grind, the axis of emery wheel and the axis of workpiece must be on same horizontal planes, to avoid both location eccentricities.
Emery wheel is thin-wall tube-shaped emery wheel, the width of its operative end surface should be made as the cone angle raceway conical surface width 1/4～1/8, can make ground effect better.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
