Hot Sale Transmission Conveyor Motorcycle/Timing /Bicycle Link Chain Roller Chain

There are usually two types of transmission mechanisms in the transmission chain: one is the transmission mechanism with fixed transmission ratio and transmission direction, such as fixed ratio gear pair, worm and turbine pair, which is called fixed ratio transmission mechanism; The other is the transmission mechanism that can change the transmission ratio and transmission direction according to the processing requirements, such as the change gear transmission mechanism, sliding gear transmission mechanism, etc., which is called the displacement mechanism.

The roller is looped on the sleeve. When working, the roller rolls along the sprocket tooth profile, which can reduce the wear of the gear teeth. The main wear of the chain occurs on the contact surface of the pin shaft and sleeve. Therefore, there should be a little gap between the inner and outer chain plates so that the lubricating oil can penetrate between the friction surfaces. The chain plate is generally made into an "8" shape, so that its cross sections have nearly equal tensile strength, and also reduce the mass of the chain and the inertia force during movement.
