Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the deviation between the center of the bearing channel and the center of the outer diameter of the bearing occurs during the processing of the existing outer ring. When the bearing channel is processed, it will inevitably leave processing marks on the outer circle of

Embodiment Construction

[0020] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0021] In this embodiment, a bearing outer ring grinding process is taken as an example of a bearing with an outer diameter of 100mm, which is manufactured according to the following steps:

[0022] 1. Prepare the blank.

[0023] Second, heat treatment. Quenching and tempering, bainite quenching, quenching temperature 820~830°C, tempering at 180±5°C after salt quenching.

[0024] 3. Grind the double end faces according to the conventional processing method.

[0025] 4. Bearing cylindrical grinding. like figure 1 As shown, the center height of the workpiece is set to 13.5 mm, the displacement of the grinding wheel relative to the outer ring of the bearing is 12 mm, the angle between the center line of the bearing outer ring workpiece and the center of the guide wheel and the line connecting the cent...

Abstract

The invention relates to a bearing outer ring grinding process and solves the problems that appearance is influenced due to the fact that processing prints are unavoidably left on an outer ring of a bearing and the outer ring needs to be ground for many times during processing of a grooved way of the bearing when the circular center of the groove way of the bearing deviates from the circular center of the outer diameter of the bearing in the prior art of processing of the outer ring. The bearing outer ring grinding process is characterized by including the following steps: grinding the outer ring of the bearing for three times, directly grinding the outer ring to be in a final size, and adopting ceramic support for grinding of the grooved way of the outer ring of the bearing. The grooved way and the outer diameter are good in concentricity, process turnover is reduced, production efficiency of the outer ring is improved, grinding time and processing cost are reduced, wall thickness difference is high in controllability, and roundness accuracy of the grooved way of the outer ring is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bearing manufacturing, in particular to a grinding process of a bearing outer ring. Background technique [0002] Centerless grinding of bearing outer circle is one of the commonly used processing methods for bearing outer rings. It is the most widely used for small and medium-sized bearings, and the processing effect is also good. Since the center of the bearing cannot be determined during the centerless grinding process of the outer circle of the bearing, the centerless grinding of the outer diameter of the bearing outer ring needs to be performed after the groove grinding, which will cause the center of the bearing groove to be the same as the center of the outer diameter of the bearing There is a deviation. However, in the conventional groove processing technology of the outer ring of the bearing, it is inevitable to leave processing marks on the outer circle of the bearing, which affects the appeara...
