  • Common Problems of Worm Gear and Worm Reducer
  • Editor:Hangzhou Xingshun Machinery Co., Ltd.Date2018-08-23 16:36 Click

Worm gear and worm reducer is a kind of transmission machine with compact structure, large transmission ratio and self-locking function under certain conditions. It is one of the most commonly used reducers. The hollow shaft worm gear reducer has not only the above characteristics, but also has convenient installation, rational structure and reasonable structure. It is more and more widely used.

澳门皇冠足彩A helical gear reducer is installed at the input end of the worm gear reducer in the hollow shaft worm gear reducer. The multi-stage reducer can achieve very low output speed. It is a combination of helical gear and gear stages. It has higher efficiency than the pure single-stage gear reducer, and has had low output speed. Less vibration, low noise and low energy consumption.

Today, a small compilation summaries the common problems of worm gear and worm reducer, and also seeks solutions!

Frequent Questions

1 Reducer Heating and Oil Leakage

In order to improve the efficiency of worm gear reducer, non-ferrous metal is generally used as wo gear reducer. RM wheel, while hard steel is used as worm. Because it is sliding friction transmission, higher heat will be generated in the operation process, which makes the thermal expansion difference between parts and seals of the reducer, resulting in clearance at various mating surfaces. Oil is easy to leak due to the increase of temperature and dilution. Leakage. There are four main reasons. One is whether the material matching is rational, the other is the surface quality of meshing friction surface, the third is the choice of lubricating oil, whether the amount of added is correct, and the fourth is the assembly quality and the use environment.

< Worm wheel wear

< Worm wheels are ge. Matched worm materials are usually hardened by 45 steel to HRC 45-55, and 40C: hardened HRC 50-55. After grinding by worm grinder to roughness RaO.8fcm, the worm is like a hardened-ldquo; file-quo; and continuous file of the wheel to wear and tear. Generally speaking, this kind of wear and tear is very slow, Like some reducers in a factory can be used for more than 10 years. If the wear rate is fast, it is necessary to consider whether the selection of reducer is correct, whether there is overload operation, worm gear and worm material, assembly quality or use environment and other reasons.

< 3. Wear of transmission helical gear

< p>ly Occurs in vertical installed reducers, mainly related to the amount of lubricating oil added and the choice of lubricating oil. Vertical installation, it is easy to cause insufficient lubricating oil. When the reducer stops running, the transmission gear oil between motor and decelerator loses, the gear can not get the proper lubrication protection On, starting or running process can not get effective lubrication leading to mechanical wear and even damage.

<4 Worm Bearing(Worm)Damage

When the gear reducer fails, even if the seal of the reducer is good, the factory often finds that gear oil in the reducer has been emulsified and the reducers have been rusted, corroded and D. This is because the gear oil is caused by moisture condensation from heat to cooling during the operation and shutdown of the reducer; of course, it is also closely related to the quality of bearings and the assembly process.
