A pulley is a mechanical component used to transmit power or motion, and belongs to the core components of a flexible transmission system. It usually consists of a wheel body (including hub, spokes and rim) and a mounting shaft hole. Pulleys are fitted with one or more pulleys through a belt to achieve the transmission of torque, speed or direction of motion. It has a wide range of applications covering industrial equipment, automobiles, agricultural machinery, household appliances and many other fields.
The core differences between European and American standard pulleys
The terms "European standard" and "American standard" for pulleys refer to the different international standard systems that their design, dimensions, tolerances, and other key parameters follow. The main differences lie in aspects such as belt type, pulley groove size, hole diameter specifications, and material standards.
Core functions
1.Power transmission: The rotating motion and torque from the driving pulley are transmitted to the driven pulley through the belt, driving other components to operate (such as the motor driving the water pump, fan, etc.).
2.Speed adjustment: Different diameter pulley combinations (variable ratio) can be used to change the output speed (such as deceleration or acceleration).
3.Direction conversion: The transmission direction can be changed using crossed belts or tensioning wheels (such as vertical or horizontal transmission).
4.Buffering and shock absorption: The belt transmission has some elasticity, which can absorb vibrations and shocks and reduce noise.
