Difference Between Roller Chain And Toothed Chain

1. The roller chain is composed of rollers, inner and outer plates, pins, etc. The rollers are cylinders with a smaller diameter, which can effectively reduce the wear of the chain and gears. The toothed chain is composed of chain plates, chain pins, etc., and has a toothed structure, which can maintain smooth and accurate movement.
2. The transmission mode of the roller chain is rolling friction. The contact area between the roller and the sprocket is large and the friction coefficient is small, so the transmission efficiency of the roller chain is high. The transmission mode of the toothed chain is adhesive friction. The contact area between the chain plate and the sprocket is small, and the friction coefficient is relatively large, so the transmission efficiency of the toothed chain is low.
3. Roller chain is suitable for transmission occasions with large load, low speed, large torque and high elasticity, such as heavy machinery, metallurgical equipment, etc. The toothed chain is suitable for transmission occasions with small load, fast speed and high precision, such as automobiles, machine tools, etc.
