In recent years, with the rapid development of the construction industry, the application of cement mixers has become more and more extensive, and the supporting bearings have been a blank in China. Due to the particularity of the working conditions of the bearing, the bearing often works continuously, the axial load is very large, and it is accompanied by impact load. The spherical roller bearing of ordinary structure cannot meet the technical requirements of high load and large self-aligning angle. Life and reliability are very low.

The outer ring is designed as a two-body radial split structure, and the inner and outer ring widths are unequal in design, which satisfies the characteristic that the aligning angle is not less than ± 6 °, and solves the problem of bearing assembly; the inner ring adds a middle rib, The axial bearing capacity of the bearing is improved; the roller adopts a semi-symmetric shape, the outer end surface is flat, and the inner end surface is a spherical base surface, which improves the stability of rotation; the cage adopts a two-body sheet structure to solve the double row roller The problem of unsynchronized operation; through the above structural improvement measures, the service life and reliability of the bearing are significantly improved. Based on the operating conditions of the bearing, based on the new structural design, the optimal design plan is selected to optimize the main design parameters, including external The width of the two bodies of the ring and the size of the raceway, the width of the rib in the inner ring, the diameter, length, and number of rolling elements, the size of the cage, and the self-aligning angle of the complete set of bearings .

The split spherical roller bearings for mixer trucks belong to the technical field of bearings; the cage is sleeved on the inner ring, the rollers are located in the inner ring and the cage, and the two bodies of the outer ring form the complete set of bearings from both sides against the inner component. The outer ring is designed as a two-body radial split structure, and the inner and outer ring widths are unequal, and the aligning angle is not less than ± 6 °; its beneficial effects are: the design structure of the bearing is optimized and the bearing is solved The problem of low bearing capacity is proved by the user, and the service life of the bearing is significantly improved to meet the user's use requirements.
