Abstract: A clutch controller provides protective disengagement of a clutch between an engine and driven machinery to prevent engine failure due to rapid onset overload. Sensor signals of measured parameters are used by the controller to determine potential engine failure. Multiple, successive sensor signals and elapsed times are assessed during which the current sensor signal value and the scaled rate of change in signal values is compared against a predefined amount. The clutch controller sends a clutch disengagement signal if a calculation result is indicative of imminent failure.

Abstract: A power takeoff (PTO) clutch unit for connection to an engine flywheel has interleaved friction disks and center plates for transfer of power to an output shaft. A pair of anti-friction bearings support the output shaft. Actuation fluid and in some cases lubrication fluid are provided at a rotary union adjacent the bearings. A spring assembly biases the PTO to a disengaged position. Gland rings are positioned about the output shaft on either side of the rotary union to allow passage of pressurized actuating and lubricating fluid to the bearings.

Abstract: A system, computer-implemented method, and computer program product are provided for a monotonic coupling assembly engagement. A coupling assembly actuation force output is increased to a coupling assembly associated with a rotary power source and a piece of driven equipment. A determination is made whether a power source process variable associated with the rotary power source drops below a pause threshold. A current coupling assembly actuation force output is maintained to the coupling assembly in response to a determination that the power source process variable drops below the pause threshold. A determination is made whether the power source process variable rises above a resume threshold. The coupling assembly actuation force output is increased to the coupling assembly in response to a determination that the power source process variable rises above the resume threshold.
