Abstract: This abnormality detection device is provided with a first encoder for detecting the rotation angle of an input shaft of a decelerator, and a second encoder for detecting the rotation angle of an output shaft of the decelerator. An operation control unit controls a servo motor such that the position acquired from the output of the second encoder corresponds to a position determined by an operation program. A detection unit calculates the angle difference, which is the difference between the rotation angle acquired from output of the first encoder and the rotation angle acquired from output of the second encoder. The detection unit determines whether or not the decelerator is abnormal on the basis of the angle difference.

Abstract: An automated system for testing a variety of transmissions and drive line gearbox components, and more particularly helicopter transmissions, for reliability, life expectancy, efficiency, and the like on a semi-automated basis. The system powers a unit under test with a pair of AC, variable speed drive motors connected to the transmission through relatively low speed gearboxes which in turn drive the input(s) of the test unit through geared cartridge spindles (GCSs) employing planetary gearset inputs driving a higher speed machine tool type spindle with an output chuck system which can automatically couple to adapters preloaded on the unit under test. Similar GCSs couple the outputs of the test unit to AC motors which act as generators to power the driving motors and thereby reduce the required electric power input to the losses in the system.

Abstract: A method to monitor a torque transfer device configured to transfer torque within an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes executing a failure detection strategy in response to a detected slip condition of the torque transfer device. The failure detection strategy includes monitoring a magnitude of energy loss of the torque transfer device. A failure condition in the torque transfer device is detected when the magnitude of energy loss achieves a predetermined energy threshold.
