Hub bearing production process

Abstract

The invention discloses a hub bearing production process, which comprises a riveting head and comprises the following steps of: 1, a hub bearing is assembled; secondly, the assembled hub bearing is placed on a clamp to be clamped; thirdly, the hub bearing is riveted and assembled by rotating a riveting head, the dip angle of the riveting head is 5.5 degrees, the middle of the riveting head protrudes, the outer right-angle side of the riveting head is changed into a negative angle, the included angle between the outer right-angle side and the horizontal plane ranges from 10 degrees to 12 degrees basically, the axial riveting assembly force is 120 kN, and the axial riveting assembly force is 120 kN; and 4, sampling inspection is performed. According to the process, the length of a contact line between the flanging flange and the small inner ring is effectively increased, and the unpressed phenomenon is reduced.

Description

technical field [0001] The invention relates to a bearing production process, in particular to a hub bearing production process. Background technique [0002] The third-generation car hub bearing is a bearing unit that directly connects the suspension and the hub through two flange end faces. There are mainly two assembly methods for this type of hub bearing unit: nut clamping assembly and riveting assembly using swing rolling technology. The oscillating rolling technology uses the periodic partial contact between the rolling head and the workpiece to apply quasi-static pressure, and the gradual deformation of the workpiece is accumulated and formed. The force is small, there is no cutting process, and there is no strong vibration and noise, and net shape processing can be realized. , Has been widely used in automobiles, machine tools, electrical appliances, light industry, lifting machinery and many other industries. The shaft riveting assembly of the hub bearing unit usi...

Problems solved by technology

When the inclination angle of the riveting head has been selected, the unreasonable shape of the riveting head will cause the riveted workpiece to be pressed incorrectly or the riveting head will interfere with the riveted workpiece, thus reducing the service life of the riveting head

If the angle between the outer straight edge of the riveting head and the horizontal line is too large (positive value), the radial fluidity of the riveted workpiece will be too large and the axial fluidity will be insufficient, which will affect the contact between the flanging flange and the small inner ring The length of the line is insufficient, and in serious cases, it may even appear that the compression cannot be realized
