Inner ring processing method in which the axis of the inner ring hole is not perpendicular to the track of the raceway

Abstract

The invention relates to a method for machining an inner ring with the axis of an inner ring hole not perpendicular to the roller path motion track. The method is characterized by comprising the following steps that (1), a standard component is mounted, the inner ring is precisely machined, and a semi-finished product is turned; (2), one end face of the inner ring is determined as a reference surface; (3), a round groove is formed in the determined reference surface to serve as a high spot recognition groove; (4), the end face of the high spot recognition groove is adopted as a reference surface, and a reference end face of alpha degrees with a hole in the bevel is ground on the other face of a roller path; (5), an outer circle is turned with the reference end face of the hole as a benchmark; (6), an inner hole is ground with the reference end face of the hole as the benchmark; and (7), the end face with the recognition groove is adopted as a benchmark, and the roller path is ground. The aim of providing the method for machining the inner ring with the axis of the inner ring hole not perpendicular to the roller path motion track is achieved, and the method is used for producing the bearing inner ring with the axis of the inner ring hole not perpendicular to the roller path motion track. The method can be suitable for common bearings, the service life is prolonged under the condition of normal use, and the pressure direction and resonance phenomenon of rotation are changed.

Description

technical field [0001] The invention relates to a processing method of a bearing, in particular to a processing method of the inner ring of the bearing. Background technique [0002] Bearings are mainly components that fix and reduce the friction coefficient of loads during mechanical transmission. When other parts move relative to each other on the shaft, the bearing can be used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings. [0003] Bearings are installed differently according to different needs. For general bearings, the general structure is that the outer ring and the inner ring are both perfect circles. During the assembly process, the outer ring and the inner ring are on the same central axis. A bearing in which the two ends of the inner ring are not parallel. Contents o...
