Non-contact dynamic torque, rotating speed and shaft power signal transducer

Abstract

The invention relates to measurement of rotation motive power of mechanical transmission as well as application of data thereof. According to the invention, an existing flexible coupler is utilized, and signal testing points are arranged on a driving half and a driven half of the flexible coupler respectively; through signal receivers arranged at the signal testing points on the two opposite coupling halves, relative positions of the driving half and the driven half during the rotation, as well as motion (rotating speed and rotating direction) signals thereof, can be obtained in a non-contact manner; and meanwhile, torque and rotating speed data can be obtained through a signal processing circuit, and the real-time shaft power of the mechanical transmission can be derived from the relation between the shaft power and the torque/the rotating speed. By the non-contact dynamic torque, rotating speed and shaft power signal transducer, the torque, the rotating speed and the shaft power in the mechanical transmission can be measured more simply and conveniently; the relevant equipment is simpler in structure, smaller in size, lighter in weight and lower in manufacture cost; the improvement of intelligentizing and lightening of the mechanical equipment is facilitated; the popularization of the intelligent mechanical equipment is facilitated; the optimization of the fit degree among the mechanical equipment is facilitated; the improvement of the mechanical transmission efficiency is facilitated; and the energy conservation and the emission reduction are facilitated.
