3m 352 9 industrial timing belt

The working mechanism of tooth belts is based on the interaction between the belt's teeth and the pulley grooves. When the pulley rotates, the teeth of the belt mesh with those of the pulley, creating a mechanical link that transmits torque. This system allows for high torque transfer with minimal backlash, which is particularly advantageous in applications requiring precise positioning, such as in robotics or CNC machines. Additionally, tooth belts operate quietly compared to chain drives, making them suitable for environments where noise reduction is essential.

A V-belt sheave is a type of pulley specifically designed to work with V-belts. These belts are named for their distinctive trapezoidal cross-section, which allows them to fit snugly into the grooves of the sheave. This design helps to maximize the contact surface area between the belt and the sheave, promoting enhanced grip and minimizing slippage. The result is an efficient system for transmitting rotational motion from one shaft to another.
