Description

Chain wheel

Technical Field

The utility model relates to a mechanical transmission technical field specifically is a sprocket.

Background

Chain transmission is one of the main forms of power transmission, and is completed by the cooperation of a chain wheel and a chain, wherein the chain wheel is the most important part in the chain transmission process.

Current sprocket can produce the vibration at the transmission in-process, makes the life of sprocket reduce, for this reason, the utility model provides a can solve a sprocket of above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sprocket, through the damping ring who sets up in order to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a sprocket comprising a sprocket body; the gear teeth are uniformly distributed on the outer surface of the chain wheel body, and arc grooves are formed among the gear teeth; the mounting hole is arranged in the center of the chain wheel body; the oil delivery pipe is arranged in the chain wheel body, one end of the oil delivery pipe is connected with the mounting hole, and the other end of the oil delivery pipe is connected with the arc groove; four groups of finger holes are uniformly distributed on the end face of the chain wheel body; two groups of outer wheel rings are arranged on the end surface of the chain wheel body; and the damping ring is arranged between the two groups of outer rings.

As an optimized technical scheme of the utility model, defeated oil pipe is the return bend.

As an optimal technical scheme of the utility model, every group the finger hole alleviates the hole by three centre of a circle on being located same circular arc and constitutes.

As an optimized technical scheme of the utility model, it is two sets of be provided with interior rim between the foreign steamer circle, the damping ring sets up in interior rim.

As an optimized technical scheme of the utility model, the centre of a circle of mounting hole, outer wheel rim and interior wheel rim is on same axis.

As an optimized technical proposal of the utility model, the inner wheel ring is higher than the outer wheel ring.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a sprocket through the damping ring that sets up for this sprocket weakens the transverse vibration of sprocket through the damping ring at the transmission in-process, has prolonged the life of sprocket.
