Gears & Clutches

Basic Function of Gears

Gears are mechanisms in which circular or semi-circular shaped gears engage each other. Gears are used for two main purposes: transmitting motion and increasing force. The contact of two gear wheels with each other functions by transmitting the motion of one rotating gear to the other gear. When larger gears are coupled to smaller gears, the number of cycles increases while the speed decreases. This allows energy to be transferred in accordance with different speed and torque requirements.

Additionally, gears can increase power transmission. The force transmitted by one gear to another is proportional to the number of teeth of the gears. Larger gears can transmit more force than smaller gears, thus providing a mechanical advantage.

Role of Clutches

Clutches are mechanisms that transmit force and movement between two shafts or shaft and wheel. Clutches generally rotate one shaft, allowing the other shaft to rotate. This can be used to change the direction of power transmission or adjust speed ratios. Clutches, also known as clutches in vehicles, are used to temporarily transmit or interrupt engine power to the wheels.

Application Areas of Gears and Clutches

Gears and clutches are used in many different applications. The use of these mechanisms is common in industrial machines, the automotive industry, watches, medical devices, robotic systems and many other areas. For example, a car's transmission system optimizes speed and torque by using different gear ratios. Industrial robots perform precise movements with the help of gears and clutches.
