In the past 10 years, with the acceleration of industrialization and urbanization in China, the machinery and equipment manufacturing industry in the whole society has achieved considerable development, and China has become the main battlefield of the international reducer industry.
The gear reducer products in the Chinese market have developed from the initial single cycloid speed reducer to the current worm gear speed reducer, planetary gear reducer, etc. Among them, planetary gear reducers are very popular among users due to their product performance comparable to military-grade speed reducers and the price of industrial-grade products, and are widely used in various fields of the national economy.
However, with more and more planetary gear reducer products and brands in the market, machinery and industrial enterprises are often at a loss when choosing a planetary gear reducer that meets requirements. How to judge the quality of planetary gear reducers has become the primary issue that machinery and industrial enterprises facing with.
As a veteran company in the field of planetary gear reducers, SGR has not only developed and iterated a variety of planetary reducer series products, but also accumulated rich experience in planetary reducer products and technologies.
Shanghai SGR Heavy Industry Machinery Co.,Ltd. will combine its many years of industry experience to share with you the methods of judging the quality of planetary gear reducers.
(1)How to determine the transmission efficiency of a planetary gear reducer?
The transmission efficiency of a planetary gear reducer actually needs to be tested with professional equipment. However, we can also make a simple judgment through two ways. The first way is to observe the appearance of the planetary reducer. A good planetary gear reducer has high dimensional accuracy, good surface, and no surface defects such as cracks, pores and other defects, which lays the foundation for higher transmission efficiency. The second way is to compare by observing the heat generation; in physics, energy is conserved. The greater the heat dissipation, the more power the motor is used to eliminate friction, and the output power is naturally less. With less output power, the load capacity is naturally weak, which will lead to a lack of force, small acceleration, and slow beat.
(2) How to simply judge the quality of a planetary gear reducer?
By observing the internal structure of the planetary gear reducer, the quality of the planetary gear reducer can be simply predicted. A good planetary gear reducer should have a compact and stable internal structure, high parts installation tightness, appropriate gear hardness and embrittlement depth, and the materials have been strictly processed and inspected to ensure that they can withstand the required load and maintain durability and stability.
（3）What other indicators of planetary gear reducers should be considered when judging their quality?
Heat, accuracy and oil leakage should all be important indicators for considering planetary reducers.
The accuracy of the planetary gear reducer depends on the degree of meshing of the gears. If the meshing clearance is too large, the accuracy of the reducer will be worse. If a micro-interference method is used, the accuracy will be improved, but it will cause excessive heat.
Generally, planetary gear reducer manufacturers have professional equipment to test angular transmission accuracy. Mechanical and industrial customers can consult the planetary gear reducer manufacturer before purchasing.
Oil leakage is a problem that all planetary reducers may face with. Oil leakage is divided into true oil leakage and false oil leakage. The so-called false oil leakage refers to oil leakage that occurs shortly after operation, the amount of oil leakage is not large, and it will not happen again after a short time. This is generally due to the release of internal pressure, and everything will be fine after the pressure is released. The time point of true oil leakage is uncertain. It may leak at the beginning, and it is likely to be a problem of product quality or assembly quality; it may also appear after a long period of operation, which is generally a problem of oil seal life, etc.
In general, when mechanical and industrial enterprises select planetary reducers, they should choose to cooperate with qualified, experienced and technical planetary gear reducer companies, and SGR is undoubtedly the best choice. (Author,SGR,Angie Zhang)
