Application of planetary reducer in coal industry

The development of industrial society has promoted the progress of the reducer industry. With the improvement of scientific and technological level, the three-ring reducer, planetary reducer, hard-tooth reducer, gear reducer and other equipment are more widely used in various industries. Next, take the planetary reducer as an example to talk about its application in the coal industry.


China is a major coal producer in the world. In order to adapt to the rapid increase in coal demand, the installed power of many coal mining machinery has increased exponentially. Therefore, the requirements for the mechanical transmission part have become higher and higher. The traditional fixed-axis gear train transmission structure can no longer meet the new working requirements. It is imperative for coal mining machinery to adopt planetary gear transmission. The planetary gear transmission of the planetary reducer has the characteristics of power diversion. Its central wheels can form a coaxial linear transmission, and the internal meshing gear pair is reasonably applied. 


Therefore, it can achieve the characteristics of small size, light weight, compact structure and strong bearing capacity.

In addition, the symmetry of the planetary reducer structure also makes the reaction force acting on the center wheel and the arm bearing balance each other, which is conducive to improving the transmission efficiency, with the efficiency value of 0.97~0.99; Due to the adoption of multiple planetary gears with the same structure, which are evenly distributed around the central wheel, the inertia force of the planetary gear and the rotating arm can be balanced, the number of gears involved in meshing can be increased, the operation of the planetary transmission is stable, the ability to resist impact and vibration is enhanced, and the working reliability is higher; Moreover, as long as the appropriate planetary gear transmission type and gear matching scheme are selected, a few gears can be used to obtain a large transmission ratio.
