Abstract
The invention discloses a retainer-free closed double-row cylindrical roller bearing, and belongs to the technical field of mechanical bearing parts. The bearing is characterized by comprising an outer ring (1), an inner ring (2), two side retainer rings (3), two rows of cylindrical roller sets (4) and two rubber seal rings (5). Compared with the prior art, the retainer-free closed double-row cylindrical roller bearing 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 without the closed Biserial cylindrical roller bearing of retainer.
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 without the closed Biserial cylindrical roller bearing of retainer.
Of the present invention a kind of without the closed Biserial cylindrical roller bearing of retainer, it is characterized in that: comprise outer ring, inner ring, two side bumper circles, two line column roller groups, two rubber seal; Wherein:
There are two in the internal diameter of described outer ring for holding the groove raceway of described two line column roller groups, in described groove raceway, scribble lubricant grease; Described outer ring being evenly equipped with due to the oil hole to oiling in bearing, in described oil hole, having the internal thread for installing screw plug;
Described inner ring and described two side bumper circle Flash Butt Weldings link together and jointly form the inner ring of described bearing, and described two side bumper circles contact with described two line column roller groups respectively;
Described two rubber seal are used for carrying out sealing to described bearing and prevent lubricant oil from overflowing, between the groove raceway that described two line column roller groups are arranged on described outer ring and described inner ring.
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 the present invention without the closed Biserial cylindrical roller bearing of retainer.
Embodiment
Fig. 1 is the structural representation of the present invention without the closed Biserial cylindrical roller bearing of retainer, of the present invention a kind of without the closed Biserial cylindrical roller bearing of retainer, it is characterized in that: comprise outer ring 1, inner ring 2, two side bumper circle 3, two line column roller groups 4, two rubber seal 5; Wherein:
There are two in the internal diameter of described outer ring 1 for holding the groove raceway of described two line column roller groups 4, in described groove raceway, scribble lubricant grease; Described outer ring 1 being evenly equipped with due to the oil hole to oiling in bearing, in described oil hole, having the internal thread for installing screw plug;
Described inner ring 2 and described two side bumper circle 3 Flash Butt Weldings link together and jointly form the inner ring of described bearing, and described two side bumper circles 3 contact with described two line column roller groups 4 respectively;
Described two rubber seal 5 prevent lubricant oil from overflowing for carrying out sealing to described bearing, between the groove raceway that described two line column roller groups 4 are arranged on described outer ring 1 and described inner ring 2.
