WPEDA70-120-200-0.75KW worm gear reducer operation and maintenance specifications, as follows:
1. Trial operation requirements : After the new machine is installed, it needs to conduct a no-load test run. The test run time is no less than 2 hours. During the test run, check whether there are abnormal noises, temperature rises and oil leakage. After the no-load test run is qualified, load test run is performed. The load needs to be gradually increased to 100% of the rated load. The load test run time is no less than 4 hours. After confirming that all parameters are normal, it can be put into formal operation.
2. Daily maintenance points
Check the lubricating oil level and quality regularly, and replace the lubricating oil every 3000 hours or 6 months (whichever comes first). When replacing, the inside of the box must be thoroughly cleaned to remove impurities and iron filings.
Regularly check seals (such as oil seals and gaskets) and replace them promptly if oil leakage occurs; check the tightening of anchor bolts and coupling bolts to prevent loosening.
Regularly monitor the operating temperature. The normal operating temperature does not exceed 80°C. If the temperature exceeds 90°C, the machine needs to be shut down for inspection to check for problems such as insufficient lubrication, excessive load, and poor heat dissipation.
3. Common faults and solutions
Abnormal noise: It may be caused by damaged bearings, poor meshing of the worm gear, or foreign matter entering the box. It is necessary to stop the machine for disassembly and inspection, replace damaged parts or adjust the meshing gap, and clean the foreign matter.
Temperature rises too fast: The oil level may be too high or too low, the lubricant model does not match, or the load is too large. It is necessary to adjust the oil level, replace the matching lubricant, or reduce the load.
Insufficient output torque: It may be caused by a mismatched transmission ratio, insufficient motor power, or serious wear of the worm gear. It is necessary to check the model parameters, replace the matching motor, or repair the transmission pair.
