Slag vertical mill reducer common failures have?

Slag vertical mill reducer common failures have? 2019 - 03 - 03 torque reducer monitoring fault signal detection. Vertical grinding machine equipment in each part, especially the important parts are belong to its own unique meshing frequency and rotating frequency, it is judged by torque signal components of various frequency is normal, if failed to provide a theoretical basis. Using torque detection system for slag vertical mill reducer running status and important components for testing, at the same time to obtain the corresponding torque curve of spectrum, based on the torque curve and spectrum analysis, check the reducer exists obvious regular vibration, if have the preliminary determine the object of breakdown and location, and then further analyze the failure, including parts damage degree, wear situation and change tendency, and according to the torque testing information arranged by proper maintenance, failure to cancel in time. Bearing fault detection and diagnosis. Vertical mill reducer and dismantling, on various planets all bearing carefully check, if find some or all of the bearing damage, such as ball bearings or inner ring and outer ring prone to severe spalling, pitting, maintains a fracture, severe wear, there are many tiny planet shelf, sheet iron, can determine the speed reducer bearing happened serious wear and damage. In the process of detection, if discover reducer planets at all levels or rusted in bearing surface, may need to be done on gear lubricant sampling inspection, if the test results show that the oil moisture, suggests that there is water seeping into the lubricating oil, cause reducer bearing and rusting of the planet carrier, reducer bearing damage caused failure.
