When people think of gears, they often first think of automotive transmissions, industrial machinery, or large equipment. However, with the development of technology, gear applications are no longer limited to traditional mechanical fields. In recent years, rapidly growing fields such as robots, humanoid robots, drones, medical equipment, and precision automation equipment have widely used various micro gears and precision gears. Although these gears are small in size, they d

In the previous article, we introduced the basic principles of gears and how gears transmit power and torque through the meshing of teeth. However, in practice, gears do not come in only one form. Depending on transmission requirements, installation direction, load conditions, and operating environment, engineers choose different types of gear designs. Some gears are suitable for high-speed operation, some are designed for high-torque output, some can change the direction of
