The chain meshes with the main and driven sprockets for secondary transmission, which is called sprocket chain transmission, or chain transmission for short.

The chain transmission structure is mainly composed of main and driven sprockets and chains. Motorcycle chain factory

The driving sprocket is installed on the transmission countershaft through splines, sprocket baffles, and screws. The driven sprocket is connected to the rear wheel through a buffer housing and a buffer block, and the power is flexibly transmitted through a rubber buffer block to reduce the transmission impact load. Motorcycle transmission chains are divided into ordinary chains and silent chains, and ordinary chains are divided into single-row chains and double-row chains. Riding-type chain transmission mainly uses single-row chains in ordinary chains. Single-row chains are divided into three types according to their structure: roller chains, sleeve chains, and sealed chains. Single-row chains are composed of inner chain links, inner chain plates, sleeves, and rollers. The outer chain links are composed of outer chain plates, pins, and connecting chain links. Many outer chain links are connected alternately into a long string, and then a live chain link is used to connect the two ends to form a ring. Chain transmission has the advantages of simple structure, easy maintenance, and economy. The disadvantages are that the lubrication conditions are poor, and the chain is loosened, the main and driven sprockets are aggravated by the suspension device, the noise is loud, and the service life is shortened.

Driving sprocket. The number of teeth of the driving sprocket has a great influence on the stability of the transmission and the service life of the chain. When the pitch of the transmission chain remains unchanged, increasing the number of teeth of the driving sprocket can increase the transmission power. However, if the number of teeth of the driving sprocket is too large and the diameter is too large, the number of teeth of the driven sprocket remains unchanged or the number of teeth of the driven gear is increased, the climbing grade will decrease, the climbing power will be weak, the power will be insufficient, the chain will jump teeth and the chain will drop, which will affect the stability of the chain transmission.
