Clutch used in farm tractors and machine tools

Introduction
In farm tractors and machine tools, the clutch is an essential component that allows the transfer of power from the engine to the transmission system. It is responsible for engaging and disengaging the power flow between the engine and the transmission. There are several types of clutches available, but the most commonly used clutch in these applications is the disc or plate clutch.

Disc or Plate Clutch
The disc or plate clutch is a type of friction clutch that consists of a set of friction plates sandwiched between a flywheel and a pressure plate. When the clutch pedal is pressed, the pressure plate moves away from the flywheel, allowing the friction plates to disengage and interrupt the power flow. Similarly, when the clutch pedal is released, the pressure plate moves towards the flywheel, forcing the friction plates to engage and transmit power.

Working Principle
The disc or plate clutch works on the principle of friction. When the clutch pedal is pressed, the pressure plate moves away from the flywheel, reducing the clamping force on the friction plates. This action allows the friction plates to rotate freely, interrupting the power flow. On the other hand, when the clutch pedal is released, the pressure plate moves towards the flywheel, increasing the clamping force on the friction plates. This force creates a frictional grip between the friction plates and the flywheel, transmitting power from the engine to the transmission.

Advantages of Disc or Plate Clutch
- High torque capacity: The disc or plate clutch can handle high torque loads, making it suitable for heavy-duty applications like farm tractors and machine tools.
- Smooth engagement: The friction plates provide a smooth engagement and disengagement of the clutch, ensuring a comfortable driving experience.
- Compact design: The disc or plate clutch has a compact design, allowing for easy installation and integration into the transmission system.
- Long service life: The friction plates are designed to withstand high temperatures and wear, resulting in a long service life.

Conclusion
The disc or plate clutch is the most commonly used clutch in farm tractors and machine tools due to its high torque capacity, smooth engagement, compact design, and long service life. It effectively transfers power from the engine to the transmission system, allowing for efficient operation of these heavy-duty applications.
