The instantaneous phase signal contains abundant information about the health state of machineries, which plays an important role in fault detection of machineries, rotor dynamic balance, transmission error of Rotate Vector reducer, etc. Traditional methods use signal processing methods based on encoders, EMD and Hilbert transforms or fractional delay filters to extract instantaneous phase information indirectly. These traditional methods are state-of-art, however those algorithms are slightly complicated and time-consuming, which is not conducive to online prognostics and health management to some extent. In fact, high precision and high reliability sensor technology can effectively reduce the complexity of subsequent signal processing. In this paper, an instantaneous phase direct detection technique based on eccentric demodulation principle is proposed. The method is derived from the kinematics between the cam and the pushrod. The laser displacement sensor is used to replace the pushrod to realize non-contact measurement. The instantaneous phase is modulation by the cam, and the proposed method can realize the obtain of the theoretical phase infinite resolution, which reaches 16,000-line resolution. Compared with the traditional encoder and other inspection technologies, the proposed method is also suitable for the measurement of broadband shifting and reciprocating motion. By means of simple signal processing methods, this paper realizes the fault diagnosis of the rolling bearing with typical defectives, and realizes the extraction and identification of the fault signal of the reciprocating compressor. Experimental results proved that the proposed inspection technology can serve as an effective technology for mechanical fault diagnosis.

“…Furthermore, the contact type between the torque sensor and the drill rod is set to "friction", and that between the torque sensor and the strain gauges is set to "binding". As for mesh generation, (11,12) a tetrahedral mesh is adopted, and the mesh on the friction surface is generated densely to improve the analysis accuracy.…”

Keywords: sleeve-type torque sensor, drill rod, linearity, coal mine, effect of strain induction To obtain the dynamic torques exerted at different location points on a wide-blade drill rod, a sleeve-type torque sensor is proposed and designed. Firstly, the relationship model between torque and voltage is built on the basis of a mechanical theory. The sensor is designed on the basis of the effect of strain induction, and its structure is designed according to the structural type of the wide-blade drill rod. Furthermore, the deformation of strain gauges is determined by finite element analysis, and the relationship between strain and torque is established. Secondly, the modal analysis of the torque sensor is performed. The hardware circuit for detecting torque is designed. Finally, the performance test is performed and, according to the test results, the performance of the sensor meets the requirements of actual working conditions. Therefore, torque can be measured using a torque sensor for the drill rod, which helps solve the problem of drill rod sticking in underground coal mine.

“…Devices designed to measure the torque can be divided into four classes according to the principle of operation: cradle dynamometers, torsional indicators, transmission dynamometers and transducers for measuring by extrinsic parameters . Torsion dynamometers are usually inertialess instruments and perform only the measuring function, enabling to record both the time averages and ever-varying values of the engine torque during its operation in any modes [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

The need for power measurement transmitted by the running shaft has led to the need for using devices for measuring torque on the shaft. Of particular importance is the power measurement on high-speed machines, wherein some cases conventional measurement systems are either unsuitable or have low accuracy. Currently, data measuring systems are widely used in the researches of turbomachines. They allow to receive, process, transmit, store and display measurement data. Their application is relevant in relation to the priority of experimental study and subsequent modeling of characteristics and performance factors of expansion machines. The purpose of this research is a design and generation of the data measuring system for measuring torque on the running shaft of vortex expansion machines using a non-contact torsional dynamometer (strain-gauge clutch). The research has considered the results of the development of data measuring system, performed a theoretical analysis and presented the results of the practical application of the non-contact strain-gauge dynamometer designed for torque measurement on the shaft of low-power expansion machines when operating under bench test conditions. Has dealt with the problems of development, calibration. Keywords: data measuring system, torque, coupling, resistive-strain sensor, vortex expansion machine.
