Abstract
The invention provides a surface carburization processing method for a steel bearing ring of a high-carbon chromium bearing which is to perform carburization heat treatment to the surface of the steel bearing ring of the high-carbon chromium bearing. The processing method comprises the steps of carburizing, quenching, tempering, carburizing, quenching and tempering. If a bearing of a car engine used in polluted oil is processed with a traditional high-carbon chromium bearing process, the abrasion performance is inferior and the service life is short which cannot meet the use demand of car engine. The invention can promote the abrasion performance and the service life of the bearing used in polluted oil by carburizing the surface of the steel bearing ring of the high-carbon chromium bearing.
Description
(1) technical field
The present invention relates to the bearing ring technical field, be specifically related to a kind of bearing ring treatment process.
(2) background technology
Bearing ring and other parts carry out carburizing thermal treatment to its surface if desired, and the used starting material of its machining bearing lasso and other parts all adopt low, medium carbon steel.After Carburization Treatment, its surperficial carbon content reaches the carbon content of high carbon chromium bearing.Because the carbon content of high carbon chromium bearing has reached 1%, adopts traditional carburization process that it is carried out carburizing, does not only reach due purpose, will reduce the service life of bearing on the contrary.
(3) summary of the invention
The object of the present invention is to provide a kind of bearing that can improve in contaminated oil, to use wear resistance and the surface carburization processing method for steel bearing ring of high-carbon chromium bearing that improves work-ing life.
The objective of the invention is to realize like this: carburizing heat treatment is carried out on high-carbon-chromium bearing steel system bearing ring surface, and processing procedure comprises carburizing → quenching → tempering → carburizing → quenching → tempering.
The present invention also has some technical characterictics like this:
1, described carburization process adopts carbon potential 1.1-2.0% carburizing 30-120min under 920-960 ℃ of environment;
2, described quenching technology is employed in quenching 30-120min under the 830-840 ℃ of environment;
3, described tempering process was employed under the 160-180 ℃ of environment tempering 3-4 hours.
The problem of aspects such as the bearing that automobile engine is used in contaminated oil adopts traditional high-carbon-chromium bearing steel processing, and existence wears no resistance, and service life is short does not reach the automobile engine instructions for use.The present invention reaches the raising bearing and in contaminated oil, uses wearability and the purpose that improves service life by carburizing is carried out on high-carbon-chromium bearing steel system bearing ring surface.
The present invention has been that carburizing and relevant thermal treatment are proceeded in 1% high carbon steel workpieces surface according to the carburizing of the thermal treatment flow process of Fig. 1 and Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and the tempered process system of quenching to carbon content; The surface hardness wear resistance and the contact fatigue life of part are further increased, satisfy the requirement of needs high-wearing feature and contact fatigue life under some specified conditions.
The present invention and traditional carburizing compare exist following different:
1. during traditional carburized material all adopts, soft steel, the carbon content on surface is up to 1% after the carburizing, present technique research be to be that 1% high carbon steel carries out carburizing to carbon content, carbon content surperficial after the carburizing is 1.2-1.8%
2. traditional carburizing thermal treatment flow process is: carburizing → quenching → tempering, the carburizing thermal treatment flow process that present technique adopts is: carburizing → quenching → tempering → carburizing → quenching → tempering.
The present invention is high-carbon chromium bearing steel, carburizing bearing ring surface, contaminated by automotive engine oils for use in the bearing inner ring carburizing heat treatment, to improve the bearing with oil pollution and improve the use of wear The purpose of life, to solve the high-carbon chromium bearing steel carburizing heat treatment is not possible technical problems, to meet the requirements of automobile engines.
