Abstract
The invention discloses a method for grinding a double-row tapered roller bearing raceway. The method includes the steps that a machine tool is adjusted to a set angle, the angle of a grinding wheel spindle is firstly adjusted, a grinding wheel is adjusted to the angle of the double-row pushing tapered roller bearing raceway so that the double-row pushing tapered roller bearing raceway is horizontally attached to the grinding wheel for grinding, after the grinding, the grinding wheel angle is the angle of one-sided raceway, then the machine tool head angle and the grinding wheel spindle angel are adjusted to form a right angle between the grinding wheel spindle and a workpiece shaft, the outer diameter of the grinding wheel is adjusted to be parallel to the raceway, the raceway machining is performed and finished according to the set accuracy, the grinding wheel spindle is moved to the centre of the raceway, the grinding wheel spindle and the raceway are adjusted to the angle between the tapered roller conical surface and a longitudinal parabolic curve to perform grinding, and the grinding is performed to achieve the set accuracy. The method for grinding the double-row tapered roller bearing raceway has the advantages that the implementation is convenient, the method is simple, the operation is easy, the work efficiency is increased by a few times, and the product quality can be guaranteed.
Description
Technical field
The present invention relates to a kind of processing method of bearing, be specifically related to a kind of double-row conical bearing ball race grinding method.
Background technology
Bearing is comprised of inner ring, outer ring, a plurality of roller and retainer usually, and a plurality of rollers are installed in respectively in the pocket hole that keeps corresponding on the stand and are placed in the raceway that is made of inner ring and outer ring, and the retainer lid is fixed on the upper surface that keeps stand.And the correction contact wire of the roller of double-row conical bearing and raceway contact point can reduce stress and concentrates, taper roll bearing can bear larger radial load and axial load, raceway with the inclination angle can make taper roll bearing bear radial and axial joint load, these characteristics make taper roll bearing become ideal selection in many application scenarios, are double-row conical bearings and use maximum in the taper roll bearing.
Biserial tapered roller thrust bearing and to depress bearing different from other tapered roller thrust bearing, the raceway wider width of these products, traditional processing method is to become irregular angle to polish with workpiece emery wheel, according to traditional processing method, the bad assurance of this angle, quality can't guarantee, and production efficiency is lower.
Summary of the invention
The purpose of this invention is to provide a kind of double-row conical bearing ball race grinding method, utilize this method processing biserial bearing rollaway nest of thrust cone roller, efficient is high, and quality meets standard.
The technical scheme that adopts is:
A kind of double-row conical bearing ball race grinding method comprises following processing step:
Lathe is adjusted to set angle, after the angle of adjusting first grinding wheel spindle is adjusted to the angle that biserial promotes the taper roll bearing raceway with emery wheel, make biserial promote taper roll bearing raceway horizontal abutment and on emery wheel, carry out reconditioning, the emery wheel angle is the angle of one-sided raceway after the finishing, adjust again lathe head of a bed angle and grinding wheel spindle angle, grinding wheel spindle and workpiece spindle angle are met at right angles, the emery wheel external diameter is adjusted to parallel with raceway, process raceway, finish raceway processing by setting accuracy, again grinding wheel spindle is moved to the raceway center, carry out reconditioning grinding wheel spindle is become the angle of the taper roller conical surface and vertical parabola with raceway after, reconditioning is to setting accuracy, and get final product.
Through evidence, the raceway face roughness of utilizing the biserial bearing rollaway nest of thrust cone roller method for grinding among the present invention to process can meet the demands, and machining angle is accurate, easily assurance, is difficult for changing, and the fault rate of processing work reduces greatly.
The invention has the advantages that:
The present invention with the emery wheel reconditioning after with set angle, be complementary with raceway angles, implement more conveniently, method is simple, and is easy to operate, operating efficiency has improved several times, and can guarantee product quality.
The specific embodiment
A kind of double-row conical bearing ball race grinding method comprises following processing step:
Lathe is adjusted to set angle, after the angle of adjusting first grinding wheel spindle is adjusted to the angle that biserial promotes the taper roll bearing raceway with emery wheel, make biserial promote taper roll bearing raceway horizontal abutment and on emery wheel, carry out reconditioning, the emery wheel angle is the angle of one-sided raceway after the finishing, adjust again lathe head of a bed angle and grinding wheel spindle angle, grinding wheel spindle and workpiece spindle angle are met at right angles, the emery wheel external diameter is adjusted to parallel with raceway, process raceway, finish raceway processing by setting accuracy, again grinding wheel spindle is moved to the raceway center, carry out reconditioning grinding wheel spindle is become the angle of the taper roller conical surface and vertical parabola with raceway after, reconditioning is to setting accuracy, and get final product.
