• What are the precautions when maintaining VF series worm gear reducer

  When maintaining the VF series worm gear reducer, you need to pay attention to lubricant inspection, temperature monitoring, sealing condition inspection, etc., as follows: Lubricant management: Lubricant must be replaced after 150-400 hours of initial use, and the oil change cycle will be less than or equal to 4000 hours. Regularly check the amount and quality of the oil to ensure sufficient lubricating oil, and replace the oil mixed with impurities or spoiled in time. When replenishing lubricating oil, the same oil as the original brand must be used. Temperature monitoring: The maximum temperature allowed by the reducer is 60℃, and the maximum oil temperature cannot exceed 100℃. If the temperature is too high, the machine should be shut down to check to see if there are problems such as excessive load, poor heat dissipation or insufficient lubrication. Sealing inspection: Check the sealing area regularly and check whether there is any oil leakage every three days. If oil leakage is found, replace aging or damaged seals in time. Preferred seals made of silicone rubber can be selected, which have better high temperature resistance. Operating status monitoring:

• ZJY300-20-What harms will abnormal vibration reducer bring about?

  ZJY300-20-S Abnormal vibration of the shaft-mounted reducer will cause harm to the equipment itself, production process, and personnel safety, as follows: Accelerating equipment wear and damage: The alternating stress and impact load generated by vibration will make key components such as gears, bearings and shafts prone to fatigue damage. The gear tooth surface may cause pitting and peeling, affecting normal meshing; the bearings may be worn, loose or damaged, reducing support and positioning performance. At the same time, vibration will loosen or break the case, fasteners and other parts, further deteriorate the equipment condition, significantly shorten the service life of the reducer, and increase maintenance costs. Causes production interruption: abnormal vibration may reduce the transmission efficiency of the reducer, insufficient output torque, and even completely lose the transmission capacity, which in turn forces the production line to shut down and overhaul. This will cause delays in production planning and delays in delivery, affecting the production efficiency and market competitiveness of enterprises, especially for automobile manufacturing, food processing, etc.

• ZJY250-15-S-axis mounted gear reducer has abnormal vibration

  The main reasons for abnormal vibration of ZJY250-15-S Axis-mounted gear reducer include mechanical failure, improper installation, lubrication problems, etc., the specifics are as follows: Mechanical component failure: Gear problem: The gear is prone to wear, pitting, peeling or cracking after a long period of operation, which will cause the meshing accuracy to decrease, thereby causing vibration. In addition, the gear manufacturing accuracy is low, installation errors are involved, or the gears are loose, which makes the gap between the gears too large and may cause vibration. Bearing problems: Bearings are the key to supporting rotating components. If the bearing is worn, poor lubrication, too large or too small, loose or cracked, the rotation will be unstable, which will cause the reducer to vibrate. Imbalance of the rotating components: If the mass distribution of rotating components such as the impeller and shaft of the reducer is uneven, and there is dynamic imbalance or static imbalance, centrifugal force will be generated during rotation, resulting in vibration. Deformation of the frame or end cover: After the reducer is running for a long time, important support parts such as the frame and end cover may be deformed.
