Abstract

The invention relates to the technical field of self-aligning roller bearings, in particular to a double-row self-aligning roller bearing with sealed nylon cages. The double-row self-aligning roller bearing comprises an outer ring bearing and an inner ring bearing. The inner ring bearing is a double-track inner ring bearing, the outer ring bearing is clamped outside the inner ring bearing, the first cage and the second cage sleeve the inner ring bearing and are arranged between the outer ring bearing and the inner ring bearing, and end surfaces between the first cage and the second cage are connected through compression. A roller is clamped between the first cage and the second cage and is a grade II roller, wherein the roundness is controlled below 0.8mum, the waviness is controlled below1.5mum, and the roughness Ra is controlled below 0.5. Sealing pieces are clamped at the two sides between the outer ring bearing and the inner ring bearing. The double-row self-aligning roller bearing is inexpensive, easy to popularize, low in vibration noise during work and long in service life.

Description

technical field [0001] The invention relates to the technical field of self-aligning roller bearings, in particular to a double-row self-aligning roller bearing with a sealed nylon cage. Background technique [0002] The spherical roller bearing used in the elevator traction machine has high requirements on the vibration noise of the bearing and the reliability of the seal. The common brass solid cage is expensive and is not conducive to environmental protection requirements. The vibration noise of the stamped steel cage It is difficult to meet the requirements. The conventional sealing structure cannot meet the reliability sealing requirements of self-alignment. The conventional rollers are easy to scratch the raceway during the assembly process, resulting in high vibration and noise, which cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to solve the disadvantages of high material cost and unsatisfactory vibration a...
