Abstract

The invention discloses a rotating speed detection device and system of a shaft to be measured. The device includes a signal toothed disc and a connection support for being installed on the end surface of the shaft to be measured, a transmission shaft coaxially arranged with the shaft to be measured is formed on the connection support, the signal toothed disc is installed on the transmission shaft, and the device also includes The sensor fixing frame is installed on the transmission shaft through bearings, and a speed sensor for detecting the speed signal of the signal toothed disk is installed on the sensor fixed frame, and the sensing end of the speed sensor is opposite to the tooth part of the signal toothed disk. The coaxial installation of the sensor fixing frame and the signal gear plate can ensure the synchronous oscillation of the two during the test, avoid the interference of other background vibrations, and improve the accuracy of the test results. The overall design of the signal chainring, bearings, sensor fixing frame, and connecting support is solidified into a component type, which is not only ingenious in design, but also easy to install and adjust, so that it can be installed in place at one time, has strong versatility, is easy to use, and is reliable.

Description

technical field [0001] The invention relates to the field of rotational speed detection, in particular to a rotational speed detection device, system and method of a shaft to be measured. Background technique [0002] When analyzing the torsional vibration of the shaft system of the engine, it is usually necessary to use the speed sensor to collect the instantaneous speed signal of the rotating shaft, and then analyze the dynamic characteristics of the rotating shaft according to the collected instantaneous speed signal, especially the torsion of the rotating shaft. Analysis of vibrations. [0003] figure 1 A schematic diagram of an existing detection device for the rotational speed of a shaft to be measured is shown. Such as figure 1 As shown, the device for detecting the rotational speed of the shaft to be measured includes: a connection support 2 and a signal toothed disc 1, and the connection support 2 is used to be installed on the end face of the shaft to be measure...
