Abstract:
A gearbox monitoring apparatus for use in combination with a gearbox which provides a connection between an input shaft and an output shaft, said gearbox monitoring apparatus comprising:a first position sensing means, and a second position sensing means, said first and second position sensing means generating a respective first output signal and a second output signal, said first output signal being representative of the angular position of said input shaft, and said second output signal being representative of an angular position of said output shaft;a torque signal generating means which generates a third output signal representative of torque carried by said gearbox; andsignal processing means receiving said output signals, said signal processing means producing a difference signal representative of the difference between said angular position of said input shaft and said output shaft from said first and second output signals, wherein said signal processing means divides said difference signal into two streams corresponding to said third output signal representative of negative torques and positive torques respectively and processes said two streams of output signals to produce at least one modified output signal representative of wear in said gearbox.
