Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] A bearing steel ball strengthening treatment device includes a vacuum treatment chamber, a rotating mechanism, a transmission mechanism, a high-voltage target platform, a plasma generator, a high-power high-voltage pulse power supply, a gas supply system, and a high-vacuum pumping system. 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 high-voltage target platform includes a target platform disc 8 and an insulating support 6. One end of the insulating support 6 is fixed on the base plate 2, and the other end is fixed on the bottom 8 of the target platform disc to support and fix it. The rotating mechanism includes a transmission shaft 13 and a dial 9; one end of the transmission shaft 13 passes through the target disc 8 and connects to the dial 9, and the other end of the transmis...

Abstract

The invention discloses a processing device for reinforcing bearing steel balls. The processing device comprises a vacuum processing chamber, a rotating mechanism, a transmission mechanism, a high-pressure target table, a plasma generator, a high-power high-voltage pulse power supply, a gas supply system and a high-vacuum exhausting system. The invention further discloses a processing method of the processing device. According to the processing device and method, complete ion implantation processing equipment is formed through cooperation of the vacuum processing chamber, the rotating mechanism, the transmission mechanism, the high-pressure target table, the plasma generator, the high-power high-voltage pulse power supply, the gas supply system and the high-vacuum exhausting system. Radio-frequency discharge is established through a radio-frequency power supply so that nitrogen, carbon and argon plasma can be discharged, and the high-power high-voltage pulse power supply provides negative high voltage pulsed bias for the processed steel balls, so that ion implantation or thin film deposition is performed. The steel balls slowly roll on a target table disc, so that the surfaces of the steel balls obtain uniform implantation dose; the reinforcing effect is better.

Description

technical field [0001] The invention relates to a bearing steel ball strengthening treatment device and a treatment method, and belongs to the field of bearing steel ball 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 countries in t...
