Planetary reducer is a common mechanical equipment accessory. There are many accessories in the planetary reducer. Many people may not know the needle roller structure inside the planetary reducer. Here is the function of the needle roller.

In the planetary reducer, the core components include planetary carrier (output shaft), ring gear, sun gear, planetary gear, needle roller, gasket and so on. Among them, needle roller plays a very important role. It is the pillar supporting the planetary gear. Through the accurate matching of the pin shaft and the positioning hole of the planetary carrier, it can reduce friction, improve efficiency and rotation. In fact, we can regard the needle roller as a small bearing, because the accuracy of the bearing is much lower than that of the needle roller, and the hardness of the needle roller is also higher than that of the bearing.

In order to achieve a planetary reducer with high precision, high strength and more wear resistance, needle roller is one of the basic control device technologies of the reducer. Moreover, the so-called low price on the market at present is that cheap plastic cage can be used to replace the needle roller. This structure can be used for production, the assembly accuracy is not high, and the strength will be relatively poor. The fine structure inside the planetary reducer is not only the fine structure of the needle roller, but also many other very important but important components, such as needle roller, can meet the working requirements of various mechanical equipment as long as the materials are exquisite. 

The above is an introduction to the function of needle roller in planetary reducer. If you need planetary reducer, please consult the manufacturer of Newgear.
