Abstract
A combined transmission assembly and monitoring system for indicating the operating condition of the transmission assembly includes a transmission assembly having an input shaft, an output shaft, and a plurality of components for connecting the output shaft for rotation at a predetermined speed relative to the input shaft, a sensor attached to a portion of the transmission assembly, the sensor being responsive to vibration of the portion of the transmission assembly for generating signals indicative of the sensed vibration, and a controller for receiving the signals from the sensor and generating an indication of the operating condition of the transmission assembly based on the vibration of the portion of the transmission assembly. Preferably the sensor is adapted to detect both the frequency and magnitude of vibration of the transmission assembly and to generate signals indicative of the sensed frequency and magnitude of vibration.
