Roller Chain consists of inner chain plate 1, outer chain plate 2, pin 3, sleeve 4 and roller 5. The pin 3 and the outer link plate 2, the sleeve 4 and the inner link plate 1 are respectively connected by interference fit. The pin 3 and the sleeve 4 and the roller 5 and the sleeve 4 have c

Roller Chain consists of inner chain plate 1, outer chain plate 2, pin 3, sleeve 4 and roller 5. The pin 3 and the outer link plate 2, the sleeve 4 and the inner link plate 1 are respectively connected by interference fit. The pin 3 and the sleeve 4 and the roller 5 and the sleeve 4 have clearance fits, so when the chain meshes with the teeth of the sprocket, there is basically rolling friction between the roller and the teeth. There is sliding friction between the sleeve and the pin, and between the roller and the sleeve. The chain plate is generally made in a figure-eight shape to make each section close to equal strength, and can reduce weight and inertia during movement.

The application range of chain transmission is: the transmission power is generally below 100kW, the efficiency is between 0.92 and 0.96, the transmission ratio i does not exceed 7, and the transmission speed is generally less than 15m / s.

The roller chain is a standard part, and its main parameters are:

Chain pitch p, which refers to the distance between the centers of two adjacent pins on the chain. GB1243.1-83 stipulates that roller chains are divided into A and B series. Multiplying the number of chain numbers in the table by 25.4 / 16 is the pitch value. The chain numbers in the table are consistent with the corresponding international standards.
