specific Embodiment approach 1

[0015] Specific implementation mode 1: This implementation mode is a method for processing the outer ring of the ball-end columnar notch of the double-row angular contact ball bearing, which is specifically completed according to the following steps:

[0016] 1. Preparation of notched parts to be processed: The bar material of the double row angular contact ball bearing to be processed is first fine-turned in turn according to the conventional processing method A side, fine-turned outer and inner diameter, inner and outer corners → fine-turned B-side, fine-turned outside Diameter, chamfering inner and outer corners → turning groove → straight slope on both sides of the car, chamfering inner corners → milling notch → deburring the notch → heat treatment → uniform rough grinding plane → final grinding plane → rough grinding outer diameter → final grinding outer diameter → fine grinding outer diameter → Coarse grinding of the outer groove → Final grinding of the outer groove → Rou...

specific Embodiment approach 2

[0020] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 2, a diamond dressing tool is used to trim the front of the parallel grinding wheel into a ball head shape, and at the same time trim the outer diameter of the parallel grinding wheel. Others are the same as the first embodiment.

specific Embodiment approach 3

[0021] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: in step 2, 1 to 2 spiral grooves are formed along the outer surface of the grinding wheel after trimming. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a machining method for a ball-head cylindrical ball-containing notch outer ring of a double-column angular contact ball bearing, and belongs to the field of bearing ferrule grinding. The invention aims to solve the problem that an existing machining method cannot meet the machining requirement of the ball-head cylindrical ball-containing notch outer ring of the double-column angular contact ball bearing. The machining method comprises the following steps of 1 preparing a to-be-machined notch part, 2 preparing a machined notch grinding wheel, 3 grinding a notch and 4 performing subsequent treatment to obtain the double-column angular contact ball bearing. The machining method has the advantages that various requirements of the double-column angular contact ball bearing are met; and a spiral groove is formed, and the easy-to-burn problem is solved. The machining method is mainly used for machining the ball-head cylindrical ball-shaped notch outer ring of the double-column angular contact ball bearing.

Description

technical field [0001] The invention belongs to the field of bearing ring grinding. Background technique [0002] At present, the usual structure of double row angular contact ball bearings is a cylindrical ball filling gap. It only needs to be ground with a cylindrical grinding wheel and the grinding wheel headstock can be adjusted to the required angle. The cylindrical notch of the ball head is based on the original columnar notch, and a spherical head is added, which adds great difficulty to the grinding process, and the existing processing methods cannot meet the processing requirements of the product. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing processing method cannot meet the processing requirements of the outer ring of the double-row angular contact ball bearing with the ball-end columnar filling notch, and to provide the outer ring of the double-row angular contact ball bearing with the ball-end...
