Abstract

The invention discloses a retainer of a spherical thrust roller bearing for a rolling mill; a tapered ring is arranged at one side of the retainer, inclined teeth are uniformly distributed at the other side of the retainer, and teeth are embedded on the tapered ring, spaces for containing cylindrical rollers are formed among the teeth, the teeth are uniformly distributed and arrayed on a circular ring; the outer diameter surface and the inner diameter surface of the tooth are consistent to the outer diameter surface and the inner diameter surface of the tapered ring, and two inner end surfaces of the teeth are planes; two sides of the outer end surface of each tooth are rounded off; the retainer of the spherical thrust roller bearing for the rolling mill has the advantages of compact structure, perfect sealing, convenient assembly and disassembly, and large automatic aligning amplitude, so as to improve the working condition and greatly improve the bearing life.

Description

technical field [0001] The invention relates to a cage of a thrust self-aligning roller bearing for a rolling mill, belonging to the technical field of thrust bearings. Background technique [0002] Thrust self-aligning roller bearings have the advantages of compact structure, perfect sealing, convenient assembly and disassembly, and large self-aligning range. The axial load shall not exceed 55% of the axial load. Compared with other thrust bearings, this kind of bearing has a lower friction coefficient, higher speed and self-aligning performance. The thrust self-aligning bearings listed in this invention are reinforced bearings with optimized design. The rollers of this kind of bearing are asymmetric spherical rollers, which can reduce the relative sliding between the rollers and the raceway during work, and the rollers are long, large in diameter, large in number and high in load capacity, and are usually lubricated with oil. Grease can be used for individual low-speed ...
