Abstract
The invention discloses a cylinder roller bearing full of rollers and having two edges provided with dustproof check rings. The cylinder roller bearing comprises an outer ring (1), an inner ring (2), rollers (3) and dustproof check rings (4); two edges of external diameter and inner bore of the outer ring (1) are chamfered with round angles; the middle of the inner bore of the outer ring (1) is provided with a cylinder roller rollway, two arc-shaped troughs are arranged in the roller rollway, and two rectangular troughs are made at the chamfers of the two edges of the inner bore; the inner ring (2) is a split structure assembled by two inner split rings symmetrically; the two rectangular troughs of the outer ring (1) and the rectangular troughs on the rough surface of the two inner split rings are symmetrically used for mounting the two dustproof check rings (4). Oil injecting holes are adopted in the invention to improve lubricating effect, thus greatly prolonging the service life of bearings.
Description
Technical Field
The invention relates to a cylindrical roller bearing with fully-loaded rollers and dustproof check rings on two sides, in particular to a cylindrical roller bearing used on a rolling mill, and belongs to the technical field of cylindrical roller bearings.
Background
The cylindrical roller bearing structure consists of an outer ring, an inner ring, a retainer and rollers, the four-row cylindrical roller bearing is used on a rolling mill of each steel rolling mill, and the bearing works under the severe working conditions of impact, high temperature, high speed, heavy load, poor lubrication, high-pressure water scouring and the like. The end part of the bearing box is provided with a sealing element which is mainly used for preventing external foreign matters such as impurities, cooling water, iron scale and the like from entering the bearing.
Foreign matters such as iron oxide scales and cooling water generated in the rolling process can enter the bearing, and lubricating grease can leak out, so that the non-fatigue damage of the bearing can be caused, the service life of the bearing is shortened, the workload of frequent grease adding of workers and the use amount and discharge amount of the grease can be increased, and the pollution to the environment is caused.
Disclosure of Invention
The invention provides a full-complement roller cylindrical roller bearing with dustproof check rings on two sides for solving the technical problems that external foreign matters enter the bearing and lubricating grease leaks out.
The invention relates to a full-complement roller cylindrical roller bearing with dustproof check rings on two sides, which comprises an outer ring, an inner ring, a roller and the dustproof check rings; the outer diameter of the outer ring and two sides of the inner hole are rounded; a cylindrical roller raceway is arranged in the middle of the inner hole of the outer ring, two arc grooves are formed in the roller raceway, and two rectangular grooves are formed at the chamfer angles close to the edges of the two sides of the inner hole; the inner ring is a split structure formed by two inner rings which are arranged in a ring-dividing symmetrical manner; the inner ring is in a step shape; the thin ring surface of the inner ring is a roller raceway, the roller raceway only has a flange on one side, and an arc groove is arranged in the roller raceway; two sides of the thick ring surface of the inner ring sub-ring are chamfered, and a rectangular groove is formed in the thick ring surface; the inner side of the joint of the two inner ring sub-rings of the inner ring is provided with an arc groove, and the arc groove is provided with oil injection holes which are uniformly distributed and point to the circle center; two sides of the inner hole of the inner ring are rounded; and the two rectangular grooves of the outer ring and the rectangular grooves on the two inner ring sub-ring thick ring surfaces are symmetrically used for mounting two dustproof check rings. The outer ring of the bearing is in interference fit with the assembly hole in the rolling mill base body, an oil injection passage is arranged on the assembly hole in the rolling mill base body, lubricating oil is injected into the arc groove in the middle of the outer wall of the outer ring of the bearing through the oil injection passage, and the lubricating oil is injected into the bearing through the oil injection hole in the arc groove.
Compared with the prior art, the invention has the following advantages: the friction is greatly reduced, the lubricating condition is improved, the lubricating quality is improved, the friction heating and the energy consumption loss are reduced, and the service life of the bearing is greatly prolonged.
