Digital analyser of a mechanical motion transmission.

摘要

Apparatus is disclosed for use in acquiring data from a mechanical motion transmission system 1 and for generating electrical signals which are indicative of the substantially instantaneous displacement, velocity and acceleration of one or more moving elements 2, 3 within the system. The said parameters can be utilized for monitoring the condition of the system, isolating faults or forecasting failures within the system; they may also be utilized as a feedback signal within a servomechanism. The said parameters are derived from a succession of electric pulses and which correspond with motion positions (equi-angular or equi-distant) associated with at least one moving element 2 within the system 1 (i.e. electrical signals generated at each fixed angle of a shaft position encoder 6). By shifting the electrical signals a predetermined amount, a novel digital filter 21 is provided for aiding in the fault isolation process.
