Abstract

The invention relates to a four-row cylindrical roller bearing for a rolling mill. Two freely rotatable rollers are clamped between two adjacent pillars in a bearing retainer. End faces of the rollers are equipped with inward concave oil storage grooves, and the edges of the pillars are provided with oil-passing grooves. A curved surface fitting the rollers is formed on one pillar side facing the rollers. The curved surface bottom of each pillar is axially provided with lubrication grooves communicated with the oil-passing grooves. A bearing outer ring, a bearing outer ring, the retainer, and the rollers are all made of a steel material. The middle retaining ring in an original bearing outer ring is abolished in the bearing, and is changed into a rolling body bearing area, the rollers are lengthened, the dynamic load of the bearing is enhanced by about 15%, and the service life is effectively improved. The adopted steel retainer has the advantages of light weight, high strength and good lubrication, thus being suitable for an expanded bearing use surface that is at a high rotation speed and does not deform in a high temperature environment.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a four-row cylindrical roller bearing for rolling mills. Background technique [0002] Nowadays, people often use four-row cylindrical roller bearings with comb-shaped copper cages in steel rolling production. Under normal working conditions, the radial load of the bearings can fully meet the requirements of rolling, and the use effect will be very good, but There are many overtravel grooves on the outer ring of the bearing, the bearing load is small, the strength of the cage is low, and the lubrication state is not good. [0003] When this type of bearing has a large rolling load, a large impact load, and a high speed, the bearing damage rate increases accordingly, which brings large economic losses to the steel mill. Contents of the invention [0004] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art, provide a fou...
