Embodiment Construction

[0039] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0040] The advantages of the sprocket of the present invention are: it has a transmission groove structure, thereby avoiding the use of transmission teeth, it is not easy to hurt hands during assembly, use or maintenance, it has high strength and long service life, and it has an oil injection hole at the same time. It can more conveniently lubricate the chain, and the transmission efficiency is higher.

[0041] Such as figure 1 The shown chain includes more than three chain link units 1 connected end to end in sequence.

[0042] Such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the chain link unit 1 includes a chai...

Abstract

The invention discloses a chain wheel. The chain wheel comprises a rim, wherein transmission grooves are uniformly formed in the outer surface of the rim and parallel to the axis of the rim. The chain wheel has the advantages as follows: the chain wheel has the transmission groove structures, so that transmission teeth are not used, the probability of hand injury in an assembly, use or maintenance process is low, the strength is higher, the service life is longer, meanwhile, water injection holes are formed, accordingly, a chain can be lubricated more conveniently, and the transmission efficiency is higher.

Description

technical field [0001] The invention relates to a transmission device, more precisely a sprocket. Background technique [0002] Chain transmission is a very common transmission method, but the gear used for chain transmission in the prior art has a high tooth height, which is easy to hurt people's hands during assembly, use or maintenance. At the same time, due to its high height, its strength is not high, thereby affecting its service life. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a structure with transmission grooves, thereby avoiding the use of transmission teeth, which is not easy to hurt hands in the process of assembly, use or maintenance, and has high strength and long service life. The sprocket is longer and has an oil injection hole, which can lubricate the chain more conveniently and has higher transmission efficiency. [0004] Above-mentioned technical problem of ...
