Abstract
A double-rotation roller bearing relates to a bearing, which comprises an inner sleeve, an outer sleeve, rollers and a retainer, wherein the center of the inner sleeve is provided with a mounting hole, a middle sleeve is arranged between the inner sleeve and the outer sleeve, the inner sleeve and the middle sleeve are correspondingly provided with an inner roller inner raceway and an inner roller outer raceway respectively, an inner retainer is arranged between the inner sleeve and the middle sleeve, the inner retainer is uniformly provided with roller holes, rollers are arranged in the roller holes, the inner roller inner raceway and the inner roller outer raceway respectively, the middle sleeve and the outer sleeve are correspondingly provided with an outer roller inner raceway and an outer roller outer raceway respectively, an outer retainer is arranged between the middle sleeve and the outer sleeve, the outer retainer is uniformly provided with roller holes, the rollers are arranged in the roller holes, the outer roller inner raceway and the outer roller outer raceway respectively, the rolling speed of the rollers is low, the abrasion speed of the bearing is slow, the service life of the, the other layer can continue to operate normally, so that more serious associated accidents caused by bearing damage are avoided.
Description
Technical field
The utility model relates to bearing, says it is a kind ofly to avoid the unexpected stall of bearing, cause related accident, the sub-bearing of two tumblers of long service life in detail.
Background technique
We know, bearing is producing, being widely used in the life at present, and like vehicular traffic, farm machinery, building machinery, engineering machinery etc., even precision type instrument such as various household electric appliance, instrument and apparatus all need use bearing.Existing bearing comprises interior cover, overcoat, roller and retainer; In cover central authorities be provided with mounting hole, interior cover with put corresponding be respectively equipped with raceway and outer raceway in the roller outward, retainer be installed in interior overlap and overcoat between; Evenly be provided with roller holes on the retainer; In roller is arranged on raceway and the outer raceway, in the roller holes, roller can be along interior raceway and outer raceway rolling, and retainer is followed the roller rotation and kept the distance between each roller.The roller rolls speed of this bearing is high, fretting corrosion speed is fast, and bearing is fragile; Need in time discovery, on-call maintenance during damage of bearings; Otherwise cause more serious accident easily; Need to stop immediately to change after the wheel bearing damage like vehicular traffic; Otherwise cause traffic accident easily, and fragile other parts, aggravation loss during precision type instrument damage of bearings such as various household electric appliance, instrument and apparatus.
Summary of the invention
The purpose of the utility model is the deficiency that solves above-mentioned existing technology, provides that a kind of roller rolls speed is low, fretting corrosion speed is slow, and the bearing long service life can continue operation after the damage of bearings, can not cause the sub-bearing of two tumblers of related accident.
The utility model is realized through following technological scheme:
A kind of pair of sub-bearing of tumbler; Comprise interior cover, overcoat, roller and retainer, interior cover central authorities are provided with mounting hole, are provided with middle cover between cover and the overcoat in it is characterized in that; In cover with in put the corresponding raceway outside the raceway and internal layer roller that is respectively equipped with in the internal layer roller; Be provided with the internal layer retainer between interior cover and the middle cover, evenly be provided with roller holes on the internal layer retainer, the outer raceway of raceway and internal layer roller is provided with roller in the roller holes, in the internal layer roller; In cover with put corresponding be respectively equipped with raceway and the outer raceway of outer roller in the outer roller outward; Be provided with outer retainer between middle cover and the overcoat, evenly be provided with roller holes on the outer retainer, raceway and the outer raceway of outer roller are provided with roller in the inside and outside layer of the roller holes roller.
Roller in the utility model can be a ball, also can be roller.
The utility model is owing to have double-deck roller, and roller rolls speed is low, and the fretting corrosion speed of bearing is slow; The bearing long service life, behind the bearing long-play, any one deck of bearing is when damaging unexpected stall; Another layer can continue normal operation, has effectively avoided because of damage of bearings causes even more serious related accident, and for keeping in repair is provided enough buffer time; Like vehicular traffic in the unexpected damage of the road upper bearing (metal) maintenance of needn't stopping at once; Vehicle can continue safety traffic, can vehicle drive just be repaired to garage, the inspection of being more convenient for, maintenance.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model, and Fig. 2 is A-A sectional view of Fig. 1.
Fig. 3 is another structural representation of the utility model, and Fig. 4 is B-B sectional view of Fig. 3.
Embodiment
The sub-bearing of two tumblers as shown in the figure; Comprise interior cover, overcoat, roller and retainer, interior cover 6 central authorities are provided with mounting hole, cover 4 in being provided with between interior cover 6 and the overcoat 1; Corresponding interior raceway of internal layer roller and the outer raceway of internal layer roller of being respectively equipped with on interior cover 6 and the middle cover 4; Be provided with internal layer retainer 5 between interior cover 6 and the middle cover 4, evenly be provided with roller holes on the internal layer retainer 5, the outer raceway of raceway and internal layer roller is provided with roller 7 in the roller holes, in the internal layer roller; Corresponding interior raceway of outer roller and the outer raceway of outer roller of being respectively equipped with on middle cover 4 and the overcoat 1; Be provided with outer retainer 2 between middle cover 4 and the overcoat 1, evenly be provided with roller holes on the outer retainer 2, raceway and the outer raceway of outer roller are provided with roller 3 in the inside and outside layer of the roller holes roller.As can be seen from Figure 2, roller adopts ball, and the bearing of processing is two deep groove ball bearings that change; As can be seen from Figure 4, roller adopts roller, and the bearing of processing is two tumbler post roller bearings.The utility model is owing to have double-deck roller, and roller rolls speed is low, and the fretting corrosion speed of bearing is slow; The bearing long service life, behind the bearing long-play, any one deck of bearing draws when damaging unexpected stall; Another layer can continue normal operation, has effectively avoided because of damage of bearings causes the even more serious band accident of coming, and is provided for maintenance enough buffer time; Like vehicular traffic in the unexpected damage of the road upper bearing (metal) maintenance of needn't stopping at once; Vehicle can continue safety traffic, can vehicle drive just be repaired to garage, the inspection of being more convenient for, maintenance.
Claims (3)
1. two sub-bearing of tumbler; Comprise interior cover, overcoat, roller and retainer, interior cover central authorities are provided with mounting hole, are provided with middle cover between cover and the overcoat in it is characterized in that; In cover with in put the corresponding raceway outside the raceway and internal layer roller that is respectively equipped with in the internal layer roller; Be provided with the internal layer retainer between interior cover and the middle cover, evenly be provided with roller holes on the internal layer retainer, the outer raceway of raceway and internal layer roller is provided with roller in the roller holes, in the internal layer roller; In cover with put corresponding be respectively equipped with raceway and the outer raceway of outer roller in the outer roller outward; Be provided with outer retainer between middle cover and the overcoat, evenly be provided with roller holes on the outer retainer, raceway and the outer raceway of outer roller are provided with roller in the inside and outside layer of the roller holes roller.
