Embodiment Construction

[0019] The load of the machine is all carried by the bearings, so there will be many problems, such as symmetry, unbalance and other problems. These problems will cause the machine to vibrate and transmit this vibration to the bearing. Therefore, we can judge whether the wind turbine is faulty and whether the bearing is defective by testing the bearing.

[0020] Bearing surfaces are often worn or otherwise damaged. The bearings are loose and unbalanced due to long-term use, improper installation of the machine and excessive load are also causes of failure.

[0021] When measuring rolling bearings in reality, the outer ring of the bearing is usually measured, and the measurement method is to place the vibration sensor on the bearing seat.

[0022] Since the low-frequency vibration below 10Hz will cause considerable displacement, the displacement sensor is generally used to measure the low-frequency vibration signal. For high-frequency vibration signals, an acceleration sensor...

Abstract

The invention discloses an automobile gearbox shaft vibration detector, which comprises a data acquisition module, a data analysis and fault diagnosis module, a communication module, a man-machine interface and a shell, wherein the man-machine interface is arranged on the front surface of the shell; the data acquisition module, the data analysis and fault diagnosis module and the communication module are arranged inside the shell; the bottom surface of the shell is provided with a vibration signal input interface area, and the area is provided with each vibration signal input interface of the data acquisition module; and the side surface of the shell is provided with a communication interface area, and the area is provided with each communication interface of the communication module. The detector integrates functions of data acquisition, data processing, fault diagnosis and strong communication as a whole, carrying and mailing are facilitated, and defects of domestic similar detection devices can be filled.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to shaft vibration detection equipment. Background technique [0002] In automobile research and development, the gearbox is also a crucial part. The automobile gearbox has the following functions: ① Change the transmission ratio, expand the range of torque and speed of the driving wheel to adapt to changing driving conditions, and at the same time make the engine work in a favorable (higher power and lower fuel consumption) working condition ②Under the condition that the rotation direction of the engine remains unchanged, the car can run backwards; ③The neutral gear is used to interrupt the power transmission, so that the engine can start and idle, and it is convenient for the transmission to shift gears or perform power output. [0003] Therefore, its performance and quality directly affect whether the shifting is smooth, whether there is a lag in starting, whether the accelera...
