Abstract
The invention discloses a heavy-load-used double-row tapered roller bearing and belongs to the technical field of mechanical bearing parts. The heavy-load-used double-row tapered roller bearing includes an integral outer ring (1), two holding frames (2), two tapered roller set rows (3) and two split-type inner rings (4). Compared with the prior art, the invention is advantaged in that the bearing is greatly reduced in friction, can improve lubricating conditions, can improve lubricating quality, can reduce friction heating and can reduce energy consumption, thereby greatly prolonging the service life of the bearing. The bearing is simple in structure, is convenient to control, is high in reliability and is convenient to repair.
Description
Technical field
The invention belongs to mechanical bearing part technical field, in particular, belong to a kind of heavy duty double-row conical 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 conical bearing.
A kind of heavy duty double-row conical bearing of the present invention, is characterized in that: comprise integral type outer race, two retainers, two row tapered roller groups and two split type inner rings; Wherein:
The internal diameter of described integral type outer race has two inclined-planes, its internal diameter is trapezoidal shape, and two inclined-planes in described integral type outer race internal diameter contact with described two row tapered roller groups respectively;
The inner ring of described bearing is described two the split type inner rings linked together by Flash Butt Welding, described two split type inner rings are coaxial, described two split type inner rings all have the groove raceway with carburized case for installing described tapered roller group, scribble lubricant grease in described groove raceway, the groove raceway of described two split type inner rings keeps symmetrical;
Described two row tapered roller groups are arranged on described two split type inner rings by described two retainers, described two row tapered roller groups keep symmetrical in the groove raceway of described two split type inner rings, and two inclined-planes of described two row tapered roller groups and described integral type outer race internal diameter keep symmetrical.
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.
