Abstract
The invention discloses a two-row ball roller bearing used for heavy load, which belongs to the technical field of machinery bearing parts. The two-row ball roller bearing is characterized by comprising a split outer ring (1) of No.45 steel, a split inner ring (2) of No.45 steel, a ball roller set (3) of No.45 steel and a holder (4) of No.45 steel. Compared with prior art, friction is greatly reduced, lubrication condition is improved, lubrication quality is increased, friction heating is reduced, energy consumption loss is reduced, bearing life is greatly increased, and the two-row ball roller bearing has the advantages of simple structure, convenient control, high reliability and easy maintenance.
Description
Technical field
The invention belongs to mechanical bearing part technical field, in particular, belong to a kind of heavy duty and use double-row-ball 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 duty double-row-ball roller bearing.
Double-row-ball roller bearing is used in a kind of heavy duty of the present invention, it is characterized in that: the retainer comprising the split outer ring of No. 45 steel, the split inner ring of No. 45 steel, the ball set of rollers of No. 45 steel and No. 45 steel; Wherein:
The inner ring of described bearing is welded together by the split inner ring of two described No. 45 steel, the split inner ring of described two No. 45 steel is coaxial, the cylindrical anchor ring of the split inner ring of described No. 45 steel has together for installing the arc groove of the ball set of rollers of described No. 45 steel; The equal rounding in internal diameter both sides of the split inner ring of described No. 45 steel, the equal rounding in external diameter both sides of the split inner ring of described No. 45 steel;
The outer ring of described bearing is welded together by the split outer ring of two described No. 45 steel, the split outer ring of described two No. 45 steel is coaxial, the cylindrical anchor ring of the split outer ring of described No. 45 steel has together for half arc groove of the ball set of rollers of fixing described No. 45 steel; The equal rounding in external diameter both sides of the split outer ring of described No. 45 steel;
The ball set of rollers of No. 45 steel described in two groups is arranged in the bearing support that the bearing inner race that is welded together by the split outer ring of the split inner ring of two described No. 45 steel and two described No. 45 steel and bearing outer ring form by the retainer of two described No. 45 steel.
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.
