Cold milling machine milling drum bearing fault diagnosis device is a kind of intelligent fault diagnosis method for milling drum bearing based on resonance demodulation. In the field of condition monitoring and fault diagnosis, the vibration signal of the milling drum bearing is collected in real time, the working state of the milling drum is monitored and the bearing fault is diagnosed. The patent has original innovation, fills gaps at home and abroad in the industry, and has completely independent intellectual property rights.
The road surface cold planer load adjustment device is based on the engine speed and power curve. The engine speed is taken as the main monitoring object. After the calculation of the central controller, the milling feed rate is automatically controlled to automatically adjust the driving and milling. The load of each system, such as the material, causes the milling machine to work at the maximum output power (ie, the limit load). The application of this patent not only enables the milling machine to achieve maximum construction efficiency, but also lays a foundation for promoting the technological progress of the industry, especially for the development of similar systems for self-propelled construction machinery.
