Abstract
The utility model discloses a transmission chain wheel which comprises a chain wheel body; a shaft hole and wheel teeth are arranged on the chain wheel body; and regular polygonal bosses are arranged at two sides of the chain wheel body. When in transmission, the wheel teeth of the chain wheel and a roller of a chain are stressed, the bosses at two sides of the chain wheel and a chain plate of the chain are synchronously contacted to stress, the chain plate bears a portion of transmission force, so that the abrasion on the wheel teeth of the chain wheel and the roller of the chain can be reduced, the stability in work is improved, and the service lives of the chain wheel and the chain are prolonged.
Description
Technical field
The utility model relates to machine power drive technology field, especially relates to a kind of drive sprocket.
Background technique
The chain transmission is one of mechanically operated main kind of drive.The chain transmission is to utilize chain and the gear teeth of sprocket wheel to be meshed the mechanical transmission of transferring power and motion.
There is following problem in disclosed drive sprocket at present: the sprocket wheel bi-side are the plane, the chain transmission is the roller contact transmission by the gear teeth of sprocket wheel and chain, because the gap between the two adjacent rollers is greater than the size of the gear teeth, the single Contact Transmission of the gear teeth and roller, the gear teeth and roller produce during transmission work impact and noise are larger, the gear teeth of sprocket wheel are easy to wear, and slippage phenomenon easily occurs after the wearing and tearing; Only have roller and tooth force transmission during transmission, roller, sleeve, bearing pin are stressed larger, and when faulty lubrication or speed were too high, the working surface of the bearing pin of chain and the sleeve of chain easily glued together, and gummed limits chaindriven limit speed; Chain link is elongated after the bearing pin of chain, the sleeve wearing and tearing, easily causes and jumps tooth or take off chain, affects the stability of working life and work; The chain transmission is many works under open environment, in the bad situation of lubrication and seal, very easily causes the bearing pin of chain and the wearing and tearing between the sleeve, thus the working life of sharply reducing chain.
The model utility content
Technical problem to be solved in the utility model provides a kind of drive sprocket, its objective is the wearing and tearing that reduce sprocket wheel and chain, improves the stability of work, prolongs the working life of sprocket wheel and chain.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of drive sprocket, comprise sprocket body, and described sprocket body is provided with axis hole and the gear teeth, and described sprocket body both sides are provided with the boss of regular polygon.
Each angle of the boss of described regular polygon is fillet.
The tooth top of the described gear teeth and side are the cambered surface transition.
The boss of described regular polygon is the boss of octagon.
The utility model compared with prior art, have the following advantages: during transmission, when the gear teeth of sprocket wheel and the roller of chain are stressed, the carrier bar contact of the boss of sprocket wheel both sides and chain, carrier bar is born the driving force of a part, reduce the wearing and tearing of the roller of the gear teeth of sprocket wheel and chain, improved the stability of work, prolonged the working life of sprocket wheel and chain.
Description of drawings
Fig. 1 is the utility model sprocket wheel organigram.
Fig. 2 is the sectional view along A-A among Fig. 1.
Fig. 3 is the utility model chain drive structure schematic diagram.
Among the figure: 1. sprocket body, 2. axis hole, 3. boss, the 4. gear teeth, 5. cambered surface, 6. chain, 60. carrier bars.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of drive sprocket comprises sprocket body 1, and sprocket body 1 center is provided with the axis hole 2 that cooperates with axle and the gear teeth 4 that are distributed on the sprocket body excircle.
In order to realize the purpose of this utility model, be provided with the boss 3 of octagon in sprocket body 1 both sides.During transmission, when the gear teeth 4 of sprocket wheel are stressed with the roller of chain 6, the boss 3 of sprocket wheel both sides and carrier bar 60 contacts of chain 6, carrier bar 60 is born the driving force of a part.
In order to reduce the wearing and tearing of 3 pairs of carrier bars of boss, fillet is processed at eight angles of the boss of octagon.
In order to guarantee the stability of work, reduce and take off the chain phenomenon, also reduce the gear teeth to the wearing and tearing of carrier bar, the tooth top of the described gear teeth 4 and side are cambered surface 5 transition.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technological scheme carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasion, all within protection domain of the present utility model.
