The invention belongs to the technical field of bearings, in particular to a semi-finished product of a bearing outer ring. It solves the technical problems that the existing technology is unfavorable for subsequent processing and short service life. The automobile hub mandrel forging includes a cylindrical body, an annular convex edge is arranged on the outer wall of the cylindrical body, a first annular stopper is provided at one end of the outer wall of the cylindrical body, and a second annular stopper is provided at the other end of the outer wall of the cylindrical body. , there is an inwardly extending annular shoulder on the inner wall of the cylindrical body, an inner annular raceway on one side of the annular shoulder, and an outer annular raceway on the other side, and an inner annular raceway connected with the inner annular raceway on the inner wall of the cylindrical body The inner ring anti-off groove, the inner wall of the cylindrical body also has an outer annular anti-off groove connected with the outer annular raceway, an annular groove body is provided on the annular shoulder, and an annular groove can be arranged on the annular shoulder. The above-mentioned annular groove is connected with the inner annular raceway and the outer annular raceway respectively. The invention has the advantages of being beneficial to subsequent processing and prolonging the service life.
Description
technical field [0001] The invention belongs to the technical field of bearings, in particular to a semi-finished product of a bearing outer ring. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission process of the equipment. The structure of the bearing generally includes an outer ring and an inner ring, and there are several rolling elements distributed in a circle between the outer ring and the inner ring. When manufacturing the outer ring, in order to facilitate subsequent proce...
