Toothed chains and roller chains have the following differences:
1. Structure: The toothed chain is composed of chain plates, chain pins, etc. It has a toothed structure and can keep the movement state stable and accurate. The roller chain is composed of rollers, inner and outer plates, pin shafts, etc. The rollers are cylinders with a small diameter, which can effectively reduce the wear of the chain and gears.
2. Transmission mode: 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. 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.
3. Features: The toothed chain has low noise, high reliability and high motion precision. Roller chains usually refer to precision roller chains for short pitch transmission, suitable for small power transmission.
To sum up, toothed chains and roller chains are different in structure, transmission mode and characteristics.
