Shaft Input Clutch-Brakes To Stop and Start the Pilot
OMBINATION CLUTCH-BRAKES
Mach III combination clutch-brakes provide both clutch and brake functions in one simple to install unit. When the clutch portion of the unit is engaged, power is transmitted from a source such as a continuously rotating motor to a machine component such as a shaft. When the brake is engaged, the component is held stationary.
SHAFT INPUT CLUTCH-BRAKES TO STOP AND START THE PILOT
Combination Air Engaged Clutch – Spring Engaged Brake
Function: Starting and Stopping / Holding The Pilot Mounted Component
Drive Arrangement: Shaft to Pilot Mounted Component
- One air signal is required.
- Clutch torque transmitted is proportional to the amount of air pressure applied, brake torque is a fixed value.
Operation
Applying air pressure releases the spring applied friction brake and engages the friction clutch.
Torque of the clutch is linear in response to air pressure applied above the brake release pressure.
Brake torque is fixed by spring pressure.
Mounting
Through (Mid) Shaft or End of Shaft.
Clutch Brake slides on shaft and is fixed with set screws and a customer supplied key.
Anti-rotation arm required to react, brake, and prevent rotation of the air housing.
Clutch Brakes are designed for horizontal mounting. Consult engineering if vertical mounting is required.
Applications
Stop/Start, Cycling, Indexing with input from constantly turning shaft.
Maximum RPM varies by model and is listed on the PDF detail sheet (see table below). Consult engineering if the intended application exceeds the listed maximum RPM.
Design Features
Clutch and brake combined in one unit for simplified mounting and control.
Clutch brakes are bored to suit up to the maximum shown (US & Metric) for easy installation.
Machined pilot for easy mounting of pulley or sprocket.
