Abstract
The utility model relates to a four-line cylindrical roller bearing capable of reducing the concentrated stress and not reducing the lubrication function of the bearing, comprising an outer ring, a keeping rack, four-lines of the cylindrical rollers, an inner ring and an oil inlet hole; wherein the cylindrical rollers are arranged between the outer ring and the inner ring and roll between the tracks formed by the outer ring and the inner ring and the keeping rack uniformly separates the rollers and the oil inlet hole is arranged on the end surface of the outer ring. The keeping rack is a closed window type keeping rack. A keeping rack cover and a keeping rack seat are arranged on the keeping rack. The cylindrical rollers are lengthened cylindrical rollers.
Description
Technical field
The utility model relates to field of bearings, concretely, relates to a kind of four-line column roller bearing.
Background technique
The typical FC type structure four-line column roller bearing that present Metallurgical Enterprise is installed and used on the hot strip mill production line, stress is concentrated, and makes lasso crack the source easily, causes part breaking.
Summary of the invention
The purpose of this utility model provides a kind of four-line column roller bearing that reduces concentrated stress, do not reduce the bearing lubrication function.
The utility model is made of outer ring, retainer, four-row cylindrical roller, inner ring and oil inlet hole; Cylindrical roller rolls between the track of outer ring and inner ring formation between outer ring and inner ring, and retainer separates roller between roller and roller equably, and oil inlet hole is set on the cycle surface.
Described retainer is closed window type retainer.
The retainer lid is arranged on the described retainer and keep stand.
Described cylindrical roller is the extended type cylindrical roller.
With prior art elder generation ratio, advantage of the present utility model is:
1, centre rib and two oil ducts have been cancelled in the outer ring, have reduced and may cause stress to concentrate, and make lasso crack the source, and cause the unfavorable factor of part breaking.
2, the lasso external diameter is not done oil groove, oil duct, has increased bearing ring intensity, at ring face the oil-feed structure is set, and does not reduce the bearing lubrication function.
3, cancelled the lasso centre rib after, the roller length that extended has improved the bearing capacity of bearing dynamic load rating value and bearing greatly.
4, improve the retainer structure, change closed window type retainer into, improved retainer rigidity and intensity greatly, the bearing integral life-span is improved by open form V shape retainer.
