Abstract

The invention relates to the field of bearing machining, in particular to a machining method for bearing outer rings. The machining method for bearing outer rings comprises the following steps that anannular blank plate is fetched, an annular rolling groove with a U-shaped axial section is formed in the outer circumferential surface of a core roller of a cold rolling machine, and two inclined surfaces of the annular rolling groove have the same angle; and the blank plate is placed in the cold rolling machine and subjected to cold rolling machining, and a semi-finished product comprising two conical bearing outer rings is obtained. Strength and abrasion resistance are high, cold deformation molding is good, surface abrasion resistance is good, the overall quality of bearing products is improved, and the service life of bearing products is prolonged, so that the continuous operating time of equipment is effectively prolonged, the maintenance period of the equipment is prolonged, and theusing cost of the equipment is saved.

Description

technical field [0001] The invention relates to the field of bearing processing, in particular to a processing method for a bearing outer ring. Background technique [0002] At present, alloy steel has a history of more than one hundred years. The industrial use of alloy steel was about the second half of the 19th century. At that time, due to the increasing production and use of steel, the machinery manufacturing industry needed to solve the problem of steel In 1868, R.F. Mushet, an Englishman, invented self-hardening steel with a composition of 2.5% Mn-7% W, which increased the cutting speed to 5 m / min. With the development of commerce and transportation, a bridge with a span of 158.5 meters was built on the Mississippi River in the United States in 1870 with chrome steel (1.5-2.0% Cr); due to difficulties in processing components, later, some industrial countries switched to nickel Steel (3.5% Ni) for building long-span bridges. At the same time, some countries also use...
