Compared with cylindrical gear reducer transmission, planetary gear reducer transmission has many unique advantages.Its obvious feature is that it can realize the separation of output power when transmitting the driving force; at the same time, its input shaft and output shaft have coaxial linearity, that is, the output shaft and input shaft are installed on the same main centerline.
Therefore, planetary gear reducer transmission has been used by us to replace ordinary gear transmission, and as a speed increaser and speed change device in various mechanical rotation systems.The main characteristics of planetary gear reducer transmission are as follows:
1. Stable operation, strong shock and vibration resistance, because multiple planetary gears with the same structure are used, which are evenly distributed around the center wheel, so that the performance of the planetary gear and the rotating arm can be balanced.At the same time, the coaxial reducer also increases the number of teeth participating in the meshing, so the movement of the planetary gear transmission is stable, the strength against shock and vibration is strong, and the work is more reliable.
2. The transmission is relatively large, which can realize the synthesis and dissolution of motion. Just choose the type of planetary gear transmission and the gear matching plan reasonably, and a very large rotation ratio can be obtained with a small number of gears.In the planetary gear reducer transmission that is only used to transmit motion, the transmission ratio can reach several thousand.It should be emphasized that when the transmission ratio of the planetary gear transmission is very large, it can still maintain many advantages such as compact structure, small quality, and small size.Moreover, it can also realize the synthesis and dissolution of motion and create complex motions with various speed adjustments.
3. The planetary gear reducer is small in size, small in quality, compact in structure, and large in bearing capacity. Because the planetary gear transmission has output power separation and the transmission of the centerline of each center wheel and the effective use of internal gear pairs, it can Make it very tight.Furthermore, in view of the fact that a plurality of planetary gears are evenly distributed around the center wheel to bear the load together, so that the load borne by each gear is small, and a smaller coefficient of variation can be selected for this gear.In addition to the coaxial reducer, the structural type flexibly utilizes the capacity volume of the diamond-grade internal gear itself, which helps to reduce its external profile size, making it small in size, small in quality, and well-structured. It is very tight and has a large bearing capacity.
4. The transmission efficiency of the planetary gear reducer is high, because of the symmetry of the planetary gear transmission structure, that is, it has multiple evenly distributed planetary gears, so that the recoil forces acting on the center wheel and the rotating arm bearing can be balanced with each other, which is beneficial To achieve the effect of improving transmission efficiency.In the case of proper selection of transmission types and effective structural layout, the high efficiency value can reach 0.97~0.99.
