Abstract
The invention discloses a four-row cylindrical roller bearing for heavy loading, and belongs to the technical field of mechanical bearing parts. The bearing is characterized by comprising two split double-row outer rings (1), two split inner rings (2), four rows of cylindrical roller sets (4) and four retainers (3). Compared with the prior art, the four-row cylindrical roller bearing for heavy loading has the advantages of greatly reducing friction, improving lubricating conditions, improving lubricating quality and reducing friction heat and energy consumption loss so as to greatly prolong the service life of the bearing, and is simple in structure, convenient to control, high in reliability, convenient to maintain and the like.
Description
Technical field
The invention belongs to mechanical bearing part technical field, in particular, belong to a kind of heavy load four-line column roller bearing.
Background technique
Bearing structure is made up of inner ring, outer ring, middle spacer ring, roller and retainer, on the milling train that heavy loaded bearing is used in each steel rolling mill and on wind-driven generator, bearing working impact, high temperature, at a high speed, under the bad working environments condition such as heavy duty, insufficient lubrication, high pressure water wash away, sand and dust.In the bearing working process that milling train uses, extraneous foreign matter is as impurity, cooling water, iron scales etc. enter in bearing, when the new bearing of firm use, its sealing effect is good, but its sealing effect is deteriorated after using a period of time, in this case as changed Sealing not in time, then sealing effect is very poor, add the reasons such as bearing mounting or dismounting frequent impact sealing, the iron scale produced in the operation of rolling, the foreign matters such as cooling water will enter in bearing, and lubricant grease also can leak, the non-fatigue ruption of bearing will be caused like this, reduce the working life of bearing, also the workload of the frequent fatten of workman can be increased, and the use amount of grease and discharge amount, cause the pollution to environment.
Usually occasion uses blower fan in desert etc., the site environment of blower fan work is also very severe, the bearing used in blower fan encounters the technical problem run in similar roller-mill bearing equally, when the new bearing of firm use, its sealing effect is good, but its sealing effect is deteriorated after using a period of time, in this case as changed Sealing not in time, then sealing effect is very poor, add the reasons such as bearing mounting or dismounting frequent impact sealing, the foreign matters such as sand extraneous in blower fan working procedure and airborne dust will enter in bearing, and lubricant grease also can leak, the non-fatigue ruption of bearing will be caused like this, reduce the working life of bearing, also the workload of the frequent fatten of workman can be increased, and the use amount of grease and discharge amount cause the pollution to blower interior, the working life of how effectively to improve blower fan middle (center) bearing is also a large key factor of restriction blower fan operating life.
Summary of the invention
The present invention, in order to effectively solve above technical problem, gives a kind of heavy load four-line column roller bearing.
A kind of heavy load four-line column roller bearing of the present invention, is characterized in that: comprise two split type double-row outer-rings, two split type inner rings, four-row cylindrical roller group and four retainers; Wherein:
The outer ring of described bearing is welded together by described two split type double-row outer-ring flash weldings, and described two split type double-row outer-rings are coaxial, two described split type double-row outer-rings all having oil hole, described oil hole having the internal thread for installing screw plug; Described split type double-row outer-ring all there are twice for locating the groove raceway of described cylindrical roller group, in described groove raceway, scribble lubricant grease;
The inner ring of described bearing is welded together by described two split type inner ring flash weldings, and described two split type inner rings are coaxial, and the external diameter of described two split type inner rings is all consistent;
Between described four-row cylindrical roller group is arranged on the described bearing be made up of described two split type double-row outer-rings outer ring respectively by described four retainers and the inner ring of described bearing be made up of described two split type inner rings.
The present invention is compared with prior art: greatly reduce friction, improve lubricating condition, improve the quality of lubrication, reduce frictional heating and energy loss, thus substantially increase bearing life, the advantages such as structure is simple, control is convenient, reliability is high, easy to maintenance.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of heavy load four-line column roller bearing of the present invention.
