SKF self-aligning roller bearing chamber is composed of double raceway inner ring, spherical raceway outer ring, double row spherical roller and retaining structure. The center of the outer raceway is identical with the center of the bearing. It has the function of automatic alignment. It can compensate the installation error between the shaft and the bearing seat or the inclination of the inner and outer rings caused by the shaft deflection. It can withstand large radial loads and certain biaxial loads. It is suitable for heavy loads or vibration occasions. SKF self-aligning roller bearings have two design structures: 20000 and 20000CA. Types A and 20000 (original code 3000) are characterized by asymmetrical spherical rollers, with a baffle in the middle of the inner ring and two independent solid cages, which are suitable for high speed applications. Type B and 20000CA (original code 53000) are characterized by symmetrical spherical rollers, no baffle in the middle of inner ring, and solid cage as a whole. They are widely used in heavy load situations. SKF self-aligning roller bearing according to the need of lubrication mode with lubricating oil groove, oil hole inner ring or outer ring products, with lubricating oil groove, oil hole characteristics code in the self-aligning roller bearing code "/" behind. Oil film bearing technology of rolling mill has been developed under the guideline of "independence and self-reliance". It is beneficial to understand, promote and develop oil film bearing technology of rolling mill. Oil film bearing technology of rolling mill is a systematic engineering technology, and it is also a multidisciplinary field. Comprehensive engineering technology of domain. 3. Research and popularization of new heat treatment technology 1. Bearings treated by bainite quenching and bainite isothermal quenching have good impact toughness and compressive stress on the surface. Whether the inner sleeve cracks during assembly or the outer sleeve edge blocks fall off during use, the tendency of inner sleeve cracking is greatly reduced, and the edge of roller can be reduced. Stress concentration.
