By adopting the technical scheme, the combination of the annular bulge, the reinforcing ring and the reinforcing ribs enhances the strength of the chain wheel, and meanwhile, the through holes and the heat dissipation holes which are formed in the wheel body in a proper amount provide a heat dissipation way for the chain wheel while the integral strength of the chain wheel is not influenced.

Preferably, a small hole is formed in the through hole, penetrates through the wheel body and extends to the position of the wheel teeth, and the small hole penetrates through the wheel teeth and is communicated with the outside.

By adopting the technical scheme, the heat generated at the gear teeth can reach the through hole along the small hole, so that the heat dissipation effect is better.

Preferably, the number of the through holes is 6.

Adopt above-mentioned technical scheme, the through-hole is mainly for the heat dissipation, but sets up too much and can influence the rigidity intensity of sprocket, so set up 6 through-holes and can realize dispelling the heat fast, can not produce great influence to the rigidity intensity of sprocket yet, guaranteed the quality of sprocket.

Preferably, the number of the reinforcing ribs is 6.

By adopting the technical scheme, the reinforcing ribs are used for enhancing the rigidity strength of the chain wheel, so that the quality of the chain wheel is better, 6 reinforcing ribs are arranged corresponding to the through holes, the appearance is attractive, and the rigidity strength of the chain wheel can be well enhanced.

Preferably, the reinforcing rib is welded to the wheel body.

By adopting the technical scheme, the welding can well enhance the quality of the chain wheel.

Preferably, the material of the chain wheel is 40Cr steel.

By adopting the technical scheme, the steel has moderate price and easy processing, can obtain certain toughness, plasticity and wear resistance after proper heat treatment, and the manufactured chain wheel has higher strength and better quality compared with other materials for manufacturing the chain wheel.

Preferably, the sound-absorbing cotton is filled in the arc-shaped groove.

Adopt above-mentioned technical scheme, inhale the sound cotton noise that can absorb the sprocket and produce in the industrial production process, play noise reduction effect, reduce the harm to staff's hearing.

Detailed Description

The following description is only a preferred embodiment of the present invention, and the protection scope is not limited to the embodiment, and any technical solution that falls under the idea of the present invention should fall within the protection scope of the present invention. It should also be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention.

As shown in fig. 1 to 4, the industrial strong sprocket comprises a sprocket body 1 and sprocket teeth 2, wherein the sprocket teeth 2 are uniformly distributed on the outer side of the sprocket body 1, a mounting groove 3 is formed in the center of the sprocket body 1, and an annular protrusion 4 is formed outside the mounting groove 3.

Seted up a plurality of through-holes 5 on the wheel body 1 for the heat dissipation, through-hole 5 is array distribution on wheel body 1, and through-hole 5 is close to the teeth of a cogwheel 2, mainly is the heat of the 2 parts of the teeth of a cogwheel of loosing, and the quantity of through-hole 5 is 6, because through-hole 5 is mainly for the heat dissipation, but sets up the rigidity intensity that too much can influence the sprocket, so set up 6 through-holes 5 and can realize dispelling the heat fast, can not produce great influence to the rigidity intensity of sprocket yet, guaranteed the quality of sprocket.
