Bearing inner ring rolling way reinforcement treatment device and treatment method

Abstract

The invention discloses a bearing inner ring rolling way reinforcement treatment device. The device comprises a vacuum treatment chamber, a high-pressure target table, a rotating mechanism, a transmission mechanism, a plasma generator, a high-power high-voltage pulse power supply, an air supply system and a high-vacuum air extracting system. The invention further discloses a treatment method. The device forms one set of complete bearing inner ring rolling way ion injection treatment equipment. A radio frequency power supply builds radio-frequency discharge nitrogen, carbon and argon plasmas; and the high-power high-voltage pulse power supply provides negative-high-pressure pulse bias voltage to a treated inner ring rolling way to perform the ion injection or film deposition treatment. The bearing inner ring on a cooling jacket slowly rotates to obtain a more uniform injection quantity on the surface, so that the bearing inner ring rolling way obtains the more uniform injection quantity, and the reinforcement treatment effect is better.

Description

technical field [0001] The invention relates to a bearing inner raceway strengthening treatment device and a treatment method, and belongs to the field of bearing inner raceway surface strengthening treatment production equipment and its manufacturing field. Background technique [0002] my country is a big country of bearing production, and the number of bearing exports ranks first in the world. However, most of the domestic bearings are medium and low-grade bearings, with low added value. In addition to the disorderly competition among enterprises, the profit margin is very low; Most of the long-life high-end bearings and special bearings urgently needed by industries such as aerospace and other high-tech and scientific research, atomic power stations, and high-speed trains need to be imported. [0003] Due to the large gap between the metallurgical quality of domestic bearing steel and foreign bearing steel, as well as the gap between domestic bearings and foreign countrie...
