SU1370449A1 - Method of estimating technical condition of gear-wheel mechanisms - Google Patents

Abstract

The invention relates to mechanical engineering, namely to means and methods for controlling gears. The circuit of the invention is an extension of the functionality by providing a more accurate determination of the technical condition of each of the gears of the mechanism under study. This is achieved by the fact that the movable part 6 of the angle converter is rigidly connected (or made touched) with the end surface of the gear wheels 16, 17, 18 of the mechanism under study, and the number of angle angle converters is chosen in accordance with the number of wheels in the gear mechanism. Thus, it is possible to process in block 10 the generation of the effective kinematic error of the signal from the converter 3 of the input gear and from any of the wheels under study, for example 19. Comparing the signals from the vibration sensor 1 and the kinematic error, information is obtained on the technical condition of the mechanism wheel under study. . 2il. with (L

The device contains a vibration sensor 1, designed to be mounted on the housing 2 of the gear mechanism being studied, converters 3-5 of the turn u-turn, consisting of a moving part 6, a fixed part 7 and a winding 8 (for example, a pulsed magnetoelectric type), amplifier 9, the input of which is connected to the output of the vibration sensor 1, the unit 10 for obtaining the effective kinematic fit-solution of the mechanism, the inputs of KOTopoi o are connected to the outputs of the angle of rotation converters 3-5, the synchronous drive 11, whose inputs are connected to the output of amplifier 9, with the output The unit for obtaining the effective kinematic error and with the outputs of the angle converters 3-5, the harmonic analysis unit 12, the inputs of which are connected to the outputs of the synchronous drive 11, and the shafts 13-15, on which the gears 16-19 are mounted.

The method is carried out as follows.

Install the vibration sensor 1 and converters 3-5 angle of rotation on the core of the housing 2 of the studied gear mechanism. When installing converters 3-5 of the angle of rotation, the movable part 6 of each converter is rigidly tied (or made completely) with the end surface of the toothed rings 16-18 of the mechanism under study, the fixed part 7 with the TOI-O gear housing, and the number of converters of the angle of rotation is chosen in accordance with the number of wheels in the gear mechanism. Then gear wheels are driven in the gear-Toi o mechanism and the technical condition of the gear mechanism is determined from these vibrating sensors and turn angle converters.

From the rotation codes of the angle converters 3-5 installed in the housing 2 and on the gears 16-18, g is obtained using the unit 10 for obtaining the signal of the effective kinematic error, the effective kinematic errors of the gears of the gears 16 and 17 and 18 and 19, From the output 10 of the vibration sensor 1 s using amplifier -9, an amplified vibration signal of housing 2 is generated, excited by gears 16-19. The signals from the outputs of the unit 10 for obtaining the effective kinematic error and the amplifier 9 are fed to the input of the synchronous accumulator 11, where synchronous accumulation is carried out using pulses from the pulsed 20 transducers of the angle of rotation 3-5 to synchronize the samples. The pulses, which follow through the fixed yi of the turning of individual wheels, serve to synchronize the beginning of the selection of the periodic components 25 of the effective kinematic error and vibrations of these wheels, which can be carried out both sequentially and in parallel. The obtained periodic components are processed using a harmonic analysis unit 12. Invention Formula
