Problems solved by technology

[0002] Extra-large spherical roller bearings are mostly used in relatively harsh working environments. In the past, due to severe damage to the raceway at the gap when the rollers were installed, the bearings were noisy during operation and their life was low. This problem needs to be solved urgently

Embodiment Construction

[0010] Such as figure 1 As shown, the present invention improves the self-aligning roller bearing with roller notches, including outer ring, inner ring 1, rollers and cages. There are notches on the ribs 2 on both sides of the inner ring 1, and the two notches are separated by an angle θ The gap is 175°, the angle α between the gap and the outer diameter of the rib 2 is 5°, and the processed gap is like a "tooth pear" shape. In the previous process, there is a gap on each end face, a straight gap, and the gaps on both sides are staggered by 180°, which is changed to The last notch has an angle of 4-5°, and the notches on both ends of each row of rollers are designed to be staggered by half the angle of the rollers, that is, the notches on both sides are staggered by 175°; each row of rollers is notched on both ends of an odd number It is designed to be staggered by 180°, the notch and the outer diameter of the rib form an angle of 5°, and the processed notch is like a "tooth p...

Abstract

The invention discloses an aligning roller bearing comprising improved notches for mounting rollers. The self-aligning roller bearing comprises an outer ring, an inner ring, rollers and a cage, wherein notches are formed on the flanges on two sides of the inner ring; the angle theta between the two notches is 175 degrees; and the angle alpha between the notch and the outer diameter of the flange is 5 degrees. Accordingly, the processed notches are shaped like a toothed pear, thus achieving the auxiliary effect of helping pushing in mounting the rollers from the notches; the roller can be loaded without using much effort, thus preventing the gouges of a raceway; each line comprises 22 rollers, each line of cage pockets are arranged in a staggered manner, and the notches on two end surfaces are at a distance of half a roller, i.e., 175 degrees, thus guaranteeing that rollers can be loaded from the notches on the two surfaces at the same time by rotating the inner ring for one turn and further reducing the labor intensity of the operators.

Description

technical field [0001] The invention belongs to the technical field of bearing cold processing technology, and in particular relates to a self-aligning roller bearing with improved roller gaps. Background technique [0002] Extra-large spherical roller bearings are mostly used in relatively harsh working environments. In the past, due to severe damage to the raceway at the gap when the rollers were installed, the bearings were noisy during operation and their life was low. It is urgent to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide an improved self-aligning roller bearing with roller notch that reduces raceway scratches and labor intensity of workers. [0004] The technical solution adopted by the present invention to achieve the above purpose is: an improved self-aligning roller bearing with roller gaps, including outer rings, inner rings, rollers and retainers, and gaps are provided on the ribs on both s...
