Cause and prevention of worm gear damage of reducer

2018-04-13 17:36:45

In cylindrical worm reducer, the lubricating oil of worm gear is very important. Lubrication has an important effect on the fatigue life, friction, wear, temperature rise and vibration of rolling bearing.


Effective measures for friction and wear of gear worm. In addition, the worm gear reducer lubrication and heat, rust prevention, impact mitigation and other functions, the circular circular tooth cylindrical worm reducer lubrication function can be briefly described as follows: 1, in the worm gear contact sliding friction surface or sliding surface between the formation of a layer of oil film to separate the two surfaces, reduce the contact surface friction and wear; 2, the use of grease lubrication, can prevent external dust and other foreign bodies into the reducer, play a closing role; 3, the fatigue life of circular tooth cylindrical worm reducer, lubricants have the effect of preventing metal rust

Solution 1. Choose the installation position of worm gear reducer. If the position permits, try not to use vertical installation. When installed vertically, the amount of lubricating oil added is much more than that of water, which is easy to cause heat and oil leakage of the reducer. Establish lubrication maintenance system. The reducer can be maintained according to the "five fixed" principle of lubrication work, so that each reducer has a responsible person to check regularly, and it is found that the temperature rise is obvious, more than 40 ° C or the oil temperature exceeds 80 ° C, the quality of the oil is reduced or more copper powder is found in the oil and abnormal noise is generated, and the use should be stopped immediately, timely maintenance, troubleshooting, and replacement of the lubricating oil. The gear box cleaning and maintenance machine uses the original feed and discharge system of the gear box and the filtered lubricating oil to clean the gear box, without changing any hardware facilities of the gear box, without adding any cleaning agent, to ensure the safe operation of the gear box and the service life of the gear box. When refueling, pay attention to the amount of oil to ensure that the reducer is correctly lubricated.
