What are the potential risks of RV130-30-5.5KW worm gear reducer models
The potential risks of RV130-40-5.5KW worm gear reducer are concentrated in transmission failure, temperature rise and lubrication, structural component damage, sealing and safety, improper installation and maintenance, etc. The following is a detailed explanation in pure text:
1. Risk of transmission core failure: Worm gears are mostly made of tin bronze material, and after quenching and hardening, long-term meshing is prone to tooth surface adhesion, wear, pitting corrosion, and even tooth collapse. Especially under high load at 5.5KW power, if the meshing accuracy is insufficient and lubrication is poor, it will accelerate the wear of worm gears, leading to a decrease in transmission efficiency, an increase in backlash, and ultimately transmission failure; When subjected to high-speed heavy loads or frequent starting and stopping, the worm shaft may bend and the worm gear journal may wear due to impact loads, which can damage the geometric accuracy of the transmission.
2. Risks related to temperature rise and lubrication: Worm gear transmission has high sliding friction, and 5.5KW power is prone to generate a large amount of heat. Poor ventilation, incorrect selection of lubricating oil, or improper oil quantity can lead to high oil temperature. On the one hand, it can reduce the viscosity of the lubricating oil, deteriorate the lubrication effect, and exacerbate component wear. On the other hand, high temperature can accelerate oil seal aging, causing oil leakage; The sudden drop in oil temperature after shutdown can also cause oil emulsification, leading to bearing rust, corrosion and damage; When installed vertically, uneven distribution of lubricating oil is prone to occur, resulting in insufficient lubrication at the moment of start-up, further exacerbating wear and tear.
3. Risk of damage to structural components: The input and output bearings are weak links, and long-term high loads, poor lubrication, or coaxiality deviation can lead to bearing fatigue wear, increased clearance, abnormal noise, vibration, and even bearing jamming during operation; Long term vibration of the box may cause bolt loosening, resulting in poor sealing surface adhesion and oil leakage. At the same time, vibration can also exacerbate fatigue damage to transmission components, forming a vicious cycle.
4. Sealing and safety risks: Seals such as oil seals and gaskets are exposed to high temperatures and vibrations for a long time, which can cause aging and wear, resulting in lubricant leakage. This not only pollutes the environment but also leads to insufficient internal lubrication; The self-locking performance may fail due to tooth wear and changes in lubrication status, which can cause safety accidents such as load slippage and positioning drift during lifting, hoisting, and other working conditions. If there is no redundant braking, the consequences will be even more serious; After oil emulsification, it may also corrode the metal parts inside the box and shorten the service life of the equipment.
5. Improper installation and maintenance risks: Excessive coaxiality deviation between the input shaft and the motor during installation can cause abnormal bearing stress, accelerated wear, and even shaft breakage; Failure to add lubricating oil according to specifications, such as mixing different types of oil or using too much or too little oil, can affect the lubrication effect; Long term failure to replace lubricating oil and clean impurities in the oil can lead to lubrication failure and accelerate the damage of transmission components; Neglecting regular inspections and failing to promptly detect issues such as tooth wear and increased bearing clearance can easily lead to minor faults escalating into major accidents.
