Tapered roller spherical end face superfinishing device

Abstract

The invention relates to the technical field of superfinishing devices, in particular to a tapered roller spherical end face superfinishing device. The tapered roller spherical end face superfinishingdevice comprises an oilstone clamp installation base, an oilstone clamp connected with the oilstone clamp installation base, an oilstone and an oilstone pressing piece, wherein the oilstone and the oilstone pressing piece are arranged in the oilstone clamp. The oilstone pressing piece is connected with an oilstone push rod assembly through a shifting piece, the oilstone push rod assembly is connected with a double-shaft air cylinder, and an oilstone discharge port is connected with a spherical end face grinding machine in a butt joint manner. The tapered roller spherical end face superfinishing device can achieve superfinishing with the tapered roller spherical end face roughness smaller than 0.08 microns through the oilstone clamp installation base, the oilstone clamp, the oilstone pushrod assembly and other components, it does not need to add new equipment or change existing equipment, and the tapered roller spherical end face superfinishing device has the advantages that type changing is rapid, adjusting is convenient, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of superfinishing devices, in particular to a superfinishing device for a spherical end surface of a tapered roller. Background technique [0002] With the country's increasing emphasis on environmental protection, fuel consumption has become an important indicator of the automotive industry. To reduce fuel consumption, it is necessary to reduce the torque and friction of each transmission component. Tapered roller bearings, which are commonly used key parts in automobiles, have become the latest research topics in the domestic bearing industry for their low torque and low friction. In order to realize the low torque of tapered roller bearings, it is first necessary to solve the low torque of tapered rollers, that is, to reduce the roughness of the spherical end surface of tapered rollers and reduce the friction between them and the ring rib. [0003] However, the domestic tapered roller industry is limite...

AI Technical Summary

Problems solved by technology

[0003] However, the domestic tapered roller industry is limited by processing equipment and processing methods. The roughness of the spherical end surface of tapered rollers is generally between 0.125um and 0.16um, and there is still a large gap to achieve low torque.

To achieve low torque, it is necessary to reduce the roughness of the spherical end surface of the tapered roller to less than 0.08um, which means that the processing method of grinding wheel grinding alone can no longer meet the roughness requirements of the market for the spherical end surface of the tapered roller.
