What are gears used for?

Gears are commonly used mechanical transmission components, primarily used to transmit power and change the form of motion. Through the meshing of gears, changes in speed, direction, and torque can be achieved, thereby meeting the working requirements of different mechanical equipment.

In the industrial field, gears are widely used in automobiles, machine tools, construction machinery, ships, and aviation equipment, among others.

For example:
Automobile transmissions use gears to adjust vehicle speed and output torque;
Gears in machine tools can control spindle speed;
Wind turbines use gearboxes to convert low-speed rotor motion into high-speed generator rotation.

In addition, gears can also be used in precision instruments and household appliances, such as clocks, printers, and electric drills, to achieve precise transmission and control.

Due to their high transmission efficiency, compact structure, and strong reliability, gears have become an indispensable core component of modern mechanical systems, playing an important role in improving mechanical performance and energy utilization efficiency.
