Embodiment Construction

[0043] In order to facilitate the understanding of various aspects, features and advantages of the technical solutions of the present invention, the present invention will be specifically described below in conjunction with the accompanying drawings. It should be understood that the various implementations described below are only for illustration, rather than limiting the protection scope of the present invention.

[0044] figure 1 An exemplary embodiment of the wireless vibration probe of the present invention is shown. Such as figure 1 As shown, the vibration probe includes: a magnetic base (i.e. an example of a base) 1, an accelerometer (i.e. an example of a sensor) 2, and a main body. Electronics inside the enclosure. Wherein, the magnetic base 1 is suitable for being installed on a rotating machine (for example, a crane reducer), for example, being adsorbed on the surface of the shell of the rotating machine by magnetic force. The accelerometer 2 is connected between...

Abstract

The invention relates to a fault diagnosis technology of rotary mechanical equipment, and provides a wireless vibration probe. The wireless vibration probe includes: a base adapted to be mounted on a rotary machine; an electronic device is arranged in the main body; the sensor is connected between the base and the main body and is used for monitoring the vibration of the rotary machine, generating a vibration time domain signal and transmitting the vibration time domain signal to the electronic device through a signal transmission line; wherein the electronic device processes the vibration time domain signal after receiving the rotating speed information of the rotating machine through the wireless module, eliminates the additional mass effect of the sensor through a frequency spectrum compensation algorithm, and finally outputs order spectrum information, and the order spectrum information is used for fault diagnosis. In the implementation mode, the vibration probe is easy to install during use, the problems of signal interference of an existing multi-channel sensor and crosstalk between analog and digital modules are solved, and the test accuracy is improved.

Description

technical field [0001] The present invention relates to fault diagnosis technology of rotating machine equipment, more specifically, relates to a wireless vibration probe used in fault diagnosis of rotating machines such as crane reducer. Background technique [0002] Lifting machinery plays an important role in people's production activities, and its safety has received widespread attention, and it has been listed as a statutory inspection object by the state. The reducer is an important part of the hoisting machinery. It works frequently, bears a large load, and the load changes in various ways. In addition, some irregular operations (such as braking against the car and stopping, etc.) cause failures from time to time and require regular maintenance. Its inspection ensures safe operation. Usually, the three parts of the gear, bearing and box of the reducer are mainly inspected. Among them, the box body can be judged whether it is invalid by visual inspection; for gears a...
