Belts and pulleysA belt drive has two advantages over a chain drive: a belt can often operate at higher speeds and does not need to be lubricated. There are various belt drives such as v-belts, toothed belts, poly-v belts, round belts, power belts, etc. The most common are the v-belt and toothed belt.
A sturdy v-belt transmission can transmit considerable power and can be an elastic transmission because of its slip. A toothed belt has no slip and is often used for greater accuracies and speeds, like behind servo and stepper motors. |
