Outer-diameter superfinishing machine tool for spherical roller

Abstract

The invention discloses an outer-diameter superfinishing machine tool for a spherical roller. The machine tool comprises a bed body, an electric control cabinet and a cooling mechanism, as well as a loading / unloading mechanism, a workpiece transmission mechanism, a swinging mechanism and a superfinishing mechanism, wherein the bed body is provided with an upright; a box body is mounted on the upright; the workpiece transmission mechanism is mounted on the front portion of the bed body; an upright and a box body are mounted on the rear portion of the workpiece transmission mechanism; the swinging mechanism comprises a swinging main shaft and an oil stone plunge cylinder; the swinging main shaft is mounted on the front end of the swinging main shaft; the oil stone plunge cylinder is mounted on the rear portion of the swinging main shaft; the loading / unloading mechanism comprises a loading path and an unloading path; the loading path is mounted on the upper portion of the box body, while the unloading path is mounted on the lower portion of the workpiece transmission mechanism; all the mechanisms are arranged in a totally enclosed housing; and the electric control cabinet is arranged on the right side of the housing. The machine tool has the advantages of low roughness degree value, low roundness, long service life and low noise, etc.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to the field of spherical roller outer diameter processing machine tools. Background technique [0002] There are four types of rolling elements used in rolling bearings, namely balls, cylindrical rollers, tapered rollers and spherical rollers. In order to make rolling bearings have good rotation accuracy, low noise, long life and good stability, the rolling elements must be Super-finishing to improve its roundness, surface roughness and waviness to reduce the running noise of the bearing and prolong the service life of the bearing. At present, my country has basically solved the superfinishing of balls, cylindrical rollers and tapered rollers, but has not solved the superfinishing technology of the outer diameter of spherical rollers. At present, domestic spherical rollers can only use light finishing to reduce the roughness value of the roller surface. The thermal s...

AI Technical Summary

Problems solved by technology

At present, domestic spherical rollers can only use light finishing to reduce the roughness value of the roller surface. The thermal stress on the surface of the roller is reduced, the roller is easy to rust, and the service life of the bearing is reduced. Therefore, the development of the spherical roller superfinishing process, tooling and equipment is a problem that the bearing industry must solve
