Intelligent monitoring method for transmission shaft

Abstract

The invention provides an intelligent monitoring method for a transmission shaft. A strain-gauge transducer, a photoelectric speed sensor, a data acquisition unit and a wireless transmitting device are embedded on the transmission shaft through a micromachining process; the strain-gauge transducer and the photoelectric speed sensor are connected with the data acquisition unit; and the data acquisition unit is connected with the wireless emitting device; a wireless receiving device is arranged on a shaft sleeve or a part which is not directly connected with the transmission shaft; the strain-gauge transducer and the photoelectric speed sensor detect operating data of the transmission shaft real time, and the operating data is processed by the data acquisition unit and continuously emitted by the wireless emitting device; and the wireless receiving device receives a signal emitted by the wireless emitting device, performs data processing and immediately emits an alarm signal when the force moment of the transmission shaft reaches or surpasses a design arrange. The method realizes on-line detection of parameters of transmission torque, speed and the like of the transmission shaft, can monitor operating parameters of equipment, performs failure prediction and alarm, and automatically stops the operation of the equipment.

Description

Problems solved by technology

[0003] Due to the rotation characteristics of the transmission shaft, it is impossible to directly transmit the measurement signal of the sensor with the signal line. Currently, conductive slip rings and toroidal transformer coupling transmission methods are mainly used. The test device is complicated and cannot meet the needs of on-site online detection.
