KB Clutch/Brake Unit Main Features
The KB series is a state-of-the-art combined clutch/brake unit with pneumatic control and dry friction material. It is engineered for seamless integration into various industrial machines, offering reliable engagement and braking. This series is ideal for:
- Eccentric Presses: Precision and high-speed operations.
- Knuckle Joint Presses: Robust performance under heavy loads.
- Metal Stamping Machines: Consistent, high-quality output.
- Edge Banders: Efficient material handling and processing.
- Punching Presses: Accurate and repetitive tasks.
- Deep Drawing Press Machines: Smooth and controlled forming processes.
- Mechanical Shears: Sharp and precise cutting actions.
- Hot Forging Machines: Withstanding high temperatures and pressures.
The pneumatic clutch/brake combination consists of an air-actuated clutch and a spring-applied brake. Its compact, straightforward design, high thermal capacity, and low air consumption make it ideal for high-speed, high-cyclic, and heavy-duty industrial applications.
Operating Principle
The operation of the KB series is straightforward yet highly efficient. When compressed air pressurizes the cylinder, the piston clamps the clutch disc to the hub, transmitting torque from the driving member to the driven shaft. Upon exhausting the air, the springs move the piston back, applying the brake and stopping the driven shaft instantly. This automatic braking occurs whenever the clutch is disengaged or when there is a pressure drop due to a leak. The design ensures that there is no overlap between clutching and braking, providing a reliable and consistent operation every time.
