Abstract
The utility model discloses a kind of anti-loose sprocket wheel, by preventing roller chain from getting loose from sprocket wheel in the large I changing tooth.It comprises wheel disc, the tooth of equal distribution on wheel disc; The tooth of diameter X-direction is provided with salient point; It is the little tooth being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction.The utility model is provided with salient point on the tooth of diameter X-direction, adds the height of tooth while meeting normal transmission, can prevent roller chain and sprocket from getting loose like this.The utility model is the little tooth being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction, and after roller chain and sprocket gets loose, roller chain can be placed into sprocket wheel lighter from little tooth position.
Description
Technical field
The utility model relates to a kind of sprocket wheel, specifically a kind of anti-loose sprocket wheel.
Background technique
Sprocket wheel be used in be in transmission connection with roller chain with the use of.Sprocket wheel has wearing and tearing to a certain degree after long-term use, all occurs in the wearing and tearing on tooth, and the tooth after wearing and tearing can diminish, and can produce the phenomenon got loose between roller chain.The environmental work that sprocket wheel is shaking, along with the vibrations of roller chain also can produce the phenomenon that gets loose.Be exactly the process of sprocket wheel in high speed rotating in addition, due to speed change greatly also can and roller chain between get loose phenomenon.
Also have existing sprocket wheel and roller chain to get loose to wait, roller chain is cumbersome when being placed on sprocket wheel, wastes time and energy.
Summary of the invention
The purpose of this utility model provides a kind of anti-loose sprocket wheel, by preventing roller chain from getting loose from sprocket wheel in the large I changing tooth.
For solving the problems of the technologies described above, the technological scheme of a kind of anti-loose sprocket wheel of the utility model is: comprise wheel disc, on wheel disc, the tooth of equal distribution, is characterized in that, the tooth of diameter X-direction is provided with salient point; It is the little tooth being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction.
The salient point of described X-direction is a pair along Y-direction symmetry; The little tooth of described Y-direction is symmetrical in X direction a pair.
Described salient point on the tooth of diameter X-direction is magnet piece.
The beneficial effects of the utility model
Compared with conventional art, the utility model is provided with salient point on the tooth of diameter X-direction, adds the height of tooth while meeting normal transmission, can prevent roller chain and sprocket from getting loose like this.The utility model is the little tooth being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction, little tooth and salient point keep certain radian, when normal transmission, little tooth can not make roller chain and sprocket get loose easily, and after roller chain and sprocket gets loose, roller chain can be placed into sprocket wheel lighter from little tooth position.
Accompanying drawing explanation
Fig. 1 is part-structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of the present embodiment.
Embodiment
By reference to the accompanying drawings the utility model is further elaborated.
As depicted in figs. 1 and 2, a kind of anti-loose sprocket wheel, comprises wheel disc 1, the tooth 2 of equal distribution on wheel disc 1; The tooth of diameter X-direction is provided with salient point 3; It is the little tooth 4 being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction.
Top circle da of the present utility model, standard pitch circle d and root circle df, the height of little tooth 4 is between standard pitch circle d and top circle da.
The utility model is provided with salient point 3 on the tooth of diameter X-direction, adds the height of tooth while meeting normal transmission, can prevent roller chain 5 and sprocket wheel from getting loose like this.
The utility model is the little tooth 4 being less than other teeth at the tooth of the diameter Y-direction vertical with X-direction, little tooth 4 keeps certain radian with salient point 3, when normal transmission, little tooth 4 can not make roller chain 5 and sprocket wheel get loose easily, and after roller chain 5 and sprocket wheel get loose, roller chain 5 can be placed into sprocket wheel lighter from little tooth 4 position.
As shown in Figure 2, the salient point 3 of described X-direction is a pair along Y-direction symmetry; The little tooth 4 of described Y-direction is symmetrical in X direction a pair.Roller chain 5 is when sprocket wheel upper driving, and when the salient point 3 of an X-direction is separated with roller chain 5, the salient point 3 of another symmetry mates with roller chain 5, can be good at preventing roller chain 5 and sprocket wheel from getting loose.Further, after roller chain 5 and sprocket wheel get loose, roller chain 5 be placed on little a pair symmetrical tooth 4 any one can, implement handiness, quick.
Described salient point 3 on the tooth of diameter X-direction is magnet piece.Roller chain 5 by the attraction of magnet piece, can better prevent roller chain 5 from getting loose from sprocket wheel on sprocket wheel.
Claims (3)
