Abstract
The invention relates to a method for forming and grinding a cylindrical roll bearing inner ring with a single retaining side or with a single retaining side and a step, and is characterized in that the method comprises the following steps: an end face of a bearing inner ring is taken as a reference, the bearing inner ring is installed on a work piece spindle of a grinding machine, the work piece spindle of the grinding machine, a grinding wheel spindle and a diamond finishing roller spindle are parallel; the work piece spindle is rotated in a vertical plane for a certain angle, so that the work piece spindle of the grinding machine, the grinding wheel spindle and a diamond finishing roller form an acute inclined angle a; a grinding wheel is finished by utilizing the diamond finishing roller having the consistent size as a molded line of an outer surface of the bearing inner ring, and the dimension of the outer surface required by the bearing inner ring is grinded by the grinding wheel once directly. The grinding wheel spindle and the diamond finishing roller form an acute inclined angle a, so that the surface on the bearing inner ring, which is parallel or vertical to the axis of the bearing inner ring can be molded at the next time under the action of the grinding wheel, and the processing efficiency is greatly improved; meanwhile, the method has the advantages of high processing precision and small axial backlash of a bearing, and the product quality is ensured.
Description
Technical field
The present invention relates to a kind of bearing grinding method, particularly a kind of single block border or single block border band step cylinder roller bearing inner ring form grinding method.
Background technology
Bearing enterprise need accurately be controlled the end-play of bearing in the process of producing bearing, and promptly the raceway width to the inside and outside circle of bearing has strict restriction.At present when work sheet rib bearing inner race; Both ends of the surface adopt the grinding of M7475B surface grinding machine symmetry, and are through the 3MZK1310A grinding machine, concrete: as shown in Figure 1 then; Workpiece, emery wheel and emery wheel parallel axes; Because emery wheel direction of feed and bearing edge guard, step rib are parallel, can't pass through grinding-shaping of emery wheel, need are spent raceway cylindrical, rib end face, step cylindrical, the step rib end face that emery wheels 3 trimming wheels 2 come the grinding bearing inner ring respectively with 90.The defective of this kind method is: 1, when grinding, need carry out the grinding of faces such as raceway cylindrical, rib end face, step cylindrical, step rib end face separately, working (machining) efficiency is very low.2, because the size scattered error of ring width causes the width of raceway to be difficult to reach technological requirement, can't guarantee the end-play of bearing.Can only guarantee play through reprocessing grinding plane adjustment width dimensions.Production cycle is long, and workload is big, and percent defective is high, and the enterprise production cost improves greatly.
Summary of the invention
The technical problem that the present invention will solve provides single block border or the single block border band step cylinder roller bearing inner ring form grinding method that a kind of working (machining) efficiency is high, end-play is little.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of single block border or single block border band step cylinder roller bearing inner ring form grinding method; Its innovative point is that said step is: be that benchmark is installed to bearing inner race on the work spindle of grinding machine with the bearing inner race end face at first, it is parallel that the work spindle of grinding machine, grinding wheel spindle and Buddha's warrior attendant are repaired the roller main shaft; With work spindle rotating certain angle in vertical plane, make work spindle and grinding wheel spindle, Buddha's warrior attendant finishing roller form an acute angle angle a again; Utilize with the Buddha's warrior attendant of bearing inner race outer surface molded lines consistent size and repair the pair of rollers crushing, go out the required outer surface size of bearing inner race by the direct grinding of emery wheel.
Further, said acute angle angle a is 45 ゜.
The invention has the advantages that: work spindle and grinding wheel spindle, Buddha's warrior attendant finishing roller form an acute angle angle a; Make on the bearing inner race parallelly or all can be in emery wheel effect moulding next time perpendicular to the surface of bearing inner race axis, Buddha's warrior attendant finishing roller can constantly be repaired emery wheel smoothly.Improved working (machining) efficiency greatly, simultaneously, machining accuracy is high, and the bearing end-play is little, guarantees product quality.

Fig. 2 is single block border cylinder roller bearing inner ring form grinding sketch map among the present invention.
Fig. 3 is single block border band step cylinder roller bearing inner ring form grinding sketch map among the present invention.
The specific embodiment
Fig. 2,3 shows single block border and single block border band step cylinder roller bearing inner ring form grinding sketch map among the present invention respectively.
The both ends of the surface of grinding bearing inner ring at first, and be benchmark with an end face of bearing inner race, through end surface supporting bearing inner race is installed on the work spindle of grinding machine.It is parallel under normal condition that the work spindle of grinding machine, grinding wheel spindle and Buddha's warrior attendant are repaired the roller main shaft.
With work spindle rotating certain angle in vertical plane, make work spindle and grinding wheel spindle, Buddha's warrior attendant finishing roller form an acute angle angle a then, promptly bearing inner race 1 axis and emery wheel 2 axis, Buddha's warrior attendant finishing roller 3 axis form an acute angle angle a.This acute angle angle a is preferably 45 ° among the present invention between 30-50 °.
The effective outer surface of Buddha's warrior attendant finishing roller 3 and the bearing inner race outer surface consistent size of designing requirement; Make emery wheel 2 effective grinding molded lines and bearing inner race 1 required outer surface consistent size, thereby go out the required outer surface size of bearing inner race 1 by emery wheel 2 direct grindings.
Claims (2)
1. single block border or single block border band step cylinder roller bearing inner ring form grinding method; It is characterized in that said step is: be that benchmark is installed to bearing inner race on the work spindle of grinding machine with the bearing inner race end face at first, it is parallel that the work spindle of grinding machine, grinding wheel spindle and Buddha's warrior attendant are repaired the roller main shaft; With work spindle rotating certain angle in vertical plane, make work spindle and grinding wheel spindle, Buddha's warrior attendant finishing roller form an acute angle angle a again; Utilize with the Buddha's warrior attendant of bearing inner race outer surface molded lines consistent size and repair the pair of rollers crushing, go out the required outer surface size of bearing inner race by the direct grinding of emery wheel.
2. single block border according to claim 1 or single block border band step cylinder roller bearing inner ring form grinding method, it is characterized in that: said acute angle angle a is 45 ゜.
