1.Introduction to Pulleys

A pulley is a common mechanical device mainly used to change the direction of force or transmit power. It consists of a wheel and a groove, with ropes or steel cables passing through the wheel. Pulleys are commonly used in situations where the direction of force needs to be altered, mechanical efficiency increased, or operational difficulty reduced. They are widely applied in various mechanical systems, especially in heavy load handling, lifting, and hoisting operations.

2.Production Process of Pulleys

The production process of pulleys generally includes the following main steps, from design to finished product shipment, ensuring structural strength, wear resistance, and service life. Below is a standard pulley production process:

Design and Engineering → Material Analysis → Preparation for Casting or Forging → Rough Machining → Heat Treatment → Finishing Machining → Surface Treatment → Inspection and Quality Control
