Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] A bearing outer raceway strengthening treatment device includes a vacuum treatment chamber, a high-vacuum pumping system, a high-voltage target stage, a plasma generator, an ion acceleration component and a gas supply system.

[0033] The vacuum processing chamber includes a bell jar 1 and a base plate 2, and the bell jar 1 is placed above the base plate 2; the present invention is provided with a lead cover 28 placed outside the bell jar and surrounded by the bell jar; the window 29 passes through the lead cover and the bell jar. During the operation of the equipment, soft X-rays and RF electromagnetic radiation will be generated at the same time. Both of them will damage the human body and must be properly protected. In the equipment, because the injection voltage is not too high, only 20-35kV, the energy of the secondary electrons hit by the ion bombardment o...

Abstract

The invention discloses a bearing outer ring roller path reinforcing treatment device and a treatment method. The bearing outer ring roller path reinforcing treatment device comprises a vacuum processing room, a high vacuum air exhaust system, a high voltage target platform, a plasma generator, an ion acceleration assembly and an air supply system. The invention also discloses a treatment method of the device. A set of complete ion injection treatment apparatus is formed by the vacuum processing room, the high vacuum air exhaust system, the high voltage target platform, the plasma generator, the ion acceleration assembly and the air supply system. A radio-frequency power supply builds radio-frequency discharge nitrogen, carbon, argon and other plasmas, and a high-power high-voltage pulse power supply is used for supplying a negative high-voltage pulsed bias to a treated steel ball, so that ion injection or thin film deposition treatment is carried out. A bearing outer ring sleeves a grid mesh electrode and a center electrode, so that a uniform injection dose can be realized for a roller path of the bearing outer ring, and the reinforcing treatment effect is good.

Description

technical field [0001] The invention relates to a bearing outer ring raceway strengthening treatment device and treatment method, and belongs to the field of bearing 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 countries in terms of desig...
