Application of precision forging in tractor gear

Precision forging (net forming or near net forming) refers to the forming technology that only needs a small amount of processing to meet the design requirements after parts are forged. It is an important branch of precision forming. It is a modern manufacturing technology based on the original forging...

Resonance demodulation method of tractor gear vibration

At present, this spectrum analysis method based on the envelope of the signal generated by high-frequency impact excitation has been proved to be a good method to solve the fault diagnosis of tractor gearbox. The advantages of resonance demodulation method include that it can distinguish the characteristic symptoms of...

Spectrum analysis method of tractor gear vibration

When the tractor gear has defects, in the process of meshing transmission, the defects will have an impact on the tractor gearbox. In the vibration signal, the phenomena of amplitude modulation and frequency modulation appear. Different faults have different manifestations in the spectrum. Identifying faults from the spectrum is...

Gear resonance demodulation of tractor gear vibration signal

When the vibration energy is large, such as broken tooth, serious tooth profile error and serious shaft bending, it will not only produce the meshing frequency modulation of tractor gear, but also arouse the natural frequency of the gear itself, resulting in the natural frequency vibration modulation of tractor...
