Abstract
The utility model discloses an integrated bearing for a belt pulley. The integrated bearing comprises an outer ring, an inner ring, and balls positioned between the inner ring and the outer ring, wherein a retainer is arranged outside the balls; sealing rings are also arranged on two sides of each ball between the inner ring and the outer ring; the outer ends of the sealing rings are clamped into channels on the inner side of the outer ring; the inner ends of the sealing rings are in contact with and seal the inner ring; frameworks for enhancing the strength are also arranged inside the sealing rings; the left and right sides of the outer ring symmetrically extend to form expanded sides; the thickness of the expanded sides is smaller than that of the outer ring. The integrated bearing has the benefits that a bearing and a belt pulley are integrated, the structure is simple, and the system accuracy is improved.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of directly can be for the bearing with transmission.
Background technique
In the time of with transmission, sometimes to use rotation idler pulley and be used as Idle wheel or take turns as transmission of power, thereby be all generally that common belt wheel is connected to by bearing the function that single shaft is realized idle running.This mode arranges rotation idler pulley complex structure, and cost is high.
Summary of the invention
In order to overcome existing rotation idler pulley complex structure, the deficiency that cost is high, it is a kind of simple in structure that the utility model provides, the belt wheel integrated bearing that cost is low.
The technical scheme in the invention for solving the technical problem is: a kind of belt wheel integrated bearing, it comprises outer ring, an inner ring, is positioned at the ball between inner ring outer ring, described ball is provided with retainer outward, between described inner ring outer ring, ball both sides are also provided with seal ring, described seal ring outer end snaps in the raceway groove of being located at inner side, outer ring, end in contact sealing inner ring in described seal ring, in described seal ring, be also provided with the skeleton of gaining in strength, symmetrical being extended with in described outer ring expanded limit, and the thickness on described expansion limit is less than the thickness of described outer ring.The existence of expanding limit makes bearing outer ring width be greater than the width of inner ring, makes belt more be not easy to come off.
For improving the bearing capacity of bearing, described ball and retainer are provided with several.
In order to adapt to V-shape belt, described outer ring and expansion limit outer concave are provided with some belt grooves.Described in during use, V-shape belt snaps in described belt grooves.
The utility model is fixed on described bearing inner race on single shaft in use, directly puts belt and can realize belt transmission on bearing outer ring and expansion limit.
The beneficial effects of the utility model are: bearing and belt pulley integrated setting, simple in structure, the precision of system improves.
Accompanying drawing explanation
Fig. 1 is an embodiment's of the utility model schematic diagram.
Fig. 2 is another embodiment's of the utility model schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment one
By reference to the accompanying drawings 1, a kind of belt wheel integrated bearing, it comprises an outer ring 1, inner ring 2, is positioned at the ball 3 of 1 of inner ring 2 outer ring, the outer retainer 4 that is provided with of described ball 3, between described inner ring outer ring, ball 3 both sides are also provided with seal ring 5, described seal ring 5 outer ends snap in the raceway groove 6 of being located at inner side, outer ring, end in contact sealing inner ring in described seal ring, in described seal ring, be also provided with the skeleton 7 of gaining in strength, symmetrical being extended with in described outer ring expanded limit 8, and the thickness on described expansion limit 8 is less than the thickness of described outer ring.The existence of expanding limit 8 makes bearing outer ring width be greater than the width of inner ring, makes belt more be not easy to come off.
The present embodiment is fixed on described bearing inner race on single shaft in use, directly puts belt and can realize belt transmission on bearing outer ring and expansion limit.
The beneficial effect of the present embodiment is: bearing and belt pulley integrated setting, simple in structure, the precision of system improves.
Embodiment two
By reference to the accompanying drawings 2, a kind of belt wheel integrated bearing described in embodiment one, its difference is that described ball 3 and retainer 4 are provided with several, are preferably two.
In order to adapt to V-shape belt, described outer ring and expansion limit outer concave are provided with some belt grooves 9, are preferably two.Described in during use, V-shape belt snaps in described belt grooves 9, and other are with embodiment one.
Claims (3)
1. a belt wheel integrated bearing, it comprises outer ring, an inner ring, is positioned at the ball between inner ring outer ring, described ball is provided with retainer outward, between described inner ring outer ring, ball both sides are also provided with seal ring, described seal ring outer end snaps in the raceway groove of being located at inner side, outer ring, end in contact sealing inner ring in described seal ring, in described seal ring, be also provided with the skeleton of gaining in strength, it is characterized in that: symmetrical being extended with in described outer ring expanded limit, and the thickness on described expansion limit is less than the thickness of described outer ring.
