Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Such as figure 1 As shown, the reinforced four-row cylindrical roller bearing includes outer ring 1, long roller 2, short roller 3, cage seat 4, cage cover 5 and inner ring 6. The long rollers 2 and short rollers 3 are installed in the outer ring 1 alternately, the cage seat 4 separates the long rollers 2 and the short rollers 3 evenly, the cage seat 4 and the cage cover 5 are riveted, and the outer ring 1. Long roller 2, short roller 3, cage seat 4, and cage cover 5 form the outer assembly, and the inner ring 6 is freely installed in the outer assembly to form a complete set of bearings.

The invention relates to an enhanced four-row cylindrical roller bearing mainly applied to a work roll of hot rolling sheet and wire rod rolling mill in steel industry. The enhanced four-row cylindrical roller bearing comprises an outer ring, long rollers, short rollers, a retainer base, a retainer cover and an inner ring, wherein the long rollers and the short rollers are staggered and arranged in the outer ring, and the retainer base separates the long rollers and the short rollers alternately; the retainer base and the retainer cover are in riveting connection; an external assembly consists of the outer ring, the long rollers, the short rollers, the retainer base and the retainer cover; and the inner ring is installed in the external assembly freely to form the whole set of bearing. The invention optimizes the design structure of the bearing, solves the difficult problem of low loading capacity, greatly prolongs the service life of the bearing and satisfies the use demands of users.
Description
technical field [0001] The invention relates to a reinforced four-row cylindrical roller bearing which is mainly used on work rolls of hot-rolled plates and wire rod mills in the iron and steel industry. Background technique [0002] Ordinary four-row cylindrical roller bearings are widely used on work rolls of hot-rolled plate and wire mills. At present, there is a common problem of low bearing capacity, which leads to early damage of bearings. According to statistical analysis, the main form of bearing damage is roller fracture. The reason for the broken rollers is that the working condition of the bearing is bad, and the rolling force is very large, which has exceeded the bearing limit of the bearing. Therefore, strengthening the bearing capacity of the roller is an effective way to improve the life of the bearing. Contents of the invention [0003] In order to enhance the bearing capacity of the rollers, the invention provides a reinforced four-row cylindrical roller...
