Abstract
The invention discloses a single row cylindrical roller bearing for overloading, and belongs to the technical field of mechanical bearing parts. The bearing comprises a screw-thread steel outer ring (1), a screw-thread steel inner ring (2), a screw-thread steel cylindrical roller set (3), a screw-thread steel retainer (4), a riveting pin (5) and a retainer sleeve (6). Compared with the prior art, the single row cylindrical roller bearing for overloading 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 duty single row 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 single row roller bearing.
A kind of heavy duty single row roller bearing of the present invention, is characterized in that: comprise Deformed Steel Bars outer ring, Deformed Steel Bars inner ring, Deformed Steel Bars cylindrical roller group, Deformed Steel Bars retainer, riveting pin and retainer cover; Wherein:
The internal diameter of described Deformed Steel Bars outer ring having one for holding the groove raceway with carburized case of described Deformed Steel Bars cylindrical roller group, in described groove raceway, scribbling lubricant grease; The external diameter of described Deformed Steel Bars inner ring has one for contact with described Deformed Steel Bars cylindrical roller group and there is the raceway of carburized case, this raceway scribbles lubricant grease; Described Deformed Steel Bars cylindrical roller group is installed between described Deformed Steel Bars outer ring and described Deformed Steel Bars inner ring by described Deformed Steel Bars retainer, and described Deformed Steel Bars cylindrical roller group is connected with being overlapped by described riveting pin and retainer between described Deformed Steel Bars retainer.
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's heavy duty single row roller bearing.
Embodiment
Fig. 1 is the structural representation of the present invention's heavy duty single row roller bearing, a kind of heavy duty single row roller bearing of the present invention, is characterized in that: comprise Deformed Steel Bars outer ring 1, Deformed Steel Bars inner ring 2, Deformed Steel Bars cylindrical roller group 3, Deformed Steel Bars retainer 4, riveting pin 5 and retainer cover 6; Wherein:
The internal diameter of described Deformed Steel Bars outer ring 1 having one for holding the groove raceway with carburized case of described Deformed Steel Bars cylindrical roller group 3, in described groove raceway, scribbling lubricant grease; The external diameter of described Deformed Steel Bars inner ring 2 has one for contact with described Deformed Steel Bars cylindrical roller group 3 and there is the raceway of carburized case, this raceway scribbles lubricant grease; Described Deformed Steel Bars cylindrical roller group 3 is installed between described Deformed Steel Bars outer ring 1 and described Deformed Steel Bars inner ring 2 by described Deformed Steel Bars retainer 4, described Deformed Steel Bars cylindrical roller group 3 with overlap 6 by described riveting pin 5 and retainer between described Deformed Steel Bars retainer 4 and be connected.
Deformed Steel Bars cylindrical roller group 3 is fixed on Deformed Steel Bars retainer 4 by riveting pin 5 and retainer cover 6; Deformed Steel Bars outer ring 1 external diameter is leaned now to one side, then to the other fillet; The equal rounding in endoporus both sides, Deformed Steel Bars outer ring 1; There is a rectangle roller raceway in the middle of the endoporus of Deformed Steel Bars outer ring 1, in roller raceway, have two arc grooves; Deformed Steel Bars inner ring 2 external diameter is leaned now to one side, then to the other fillet, the equal rounding in Deformed Steel Bars inner ring 2 endoporus both sides; Deformed Steel Bars retainer 4 side is equally distributed teeth, and Deformed Steel Bars cylindrical roller group 3 is evenly distributed between teeth, teeth has the hierarchic structure of placing and keeping retainer cover 6, hierarchic structure has through hole.
