Spherical roller bearing inner and outer ring technological process: bar-forging-turning-heat treatment-grinding-super finishing-final inspection of parts-rust prevention storage
In the production process, the most important processing are as the following:
①Forging
The forging processing is an important link to ensure the reliability and life of the spherical roller bearing. After the raw material is forged, the spherical roller bearing roller bearing ring blank is formed. At the same time, the organization structure of the raw materials becomes denser and the flow linearity becomes better, which can improve the reliability and service life of the spherical roller bearing. In addition, the quality of the forging process will directly affect the utilization rate of raw materials, thereby affecting production costs.
②The heat treatment
The heat treatment process is to subject the forged and machined forged ring to high temperature treatment, which directly affects the uniformity of carburization in the spherical roller bearing ring and can improve the wear resistance of the spherical roller bearing And hardness is also an important link that affects the reliability and life of spherical roller bearings.
③Grinding
After heat treatment, the spherical roller bearing ring needs to be ground, which is an important part of ensuring the accuracy of the spherical roller bearing. After grinding, the production process of spherical roller bearing rings is basically completed.
