Why choose planetary gear drive? There may be many reasons for this, but in the final analysis, it is because of the advantages of planetary gear transmission. A planetary gearbox is composed of a planet ring gear, a sun gear, a planet wheel gear wheel shaft. Next, I will introduce its features.
- small volume, light, compact structure, large bearing capacity
Generally speaking, the outer size and mass of the planet gear drive are smaller than those of the ordinary gear under the same load.
- high transmission efficiency
Due to the symmetry of the planetary gear transmission structure, the reaction forces acting on the center wheel and the slewing bearing are balanced with each other, thereby facilitating the effect of improving the transmission efficiency.
- Large transmission ratio
Planetary gear transmission can still maintain the compact structure when the transmission ratio is large.
- Smooth movement, strong ability to resist shock and vibration
Due to the use of several planet wheels of the same structure, they are evenly distributed around the center wheel, so that the planet wheels and the arm can be balanced. At the same time, the number of teeth participating in meshing is also increased. Therefore, the planetary gear transmission is stable, the ability to resist shock and vibration is strong, and the operation is more reliable.
But its disadvantages are also obvious, the planetary drive structure is complicated. Gear stage such as single-stage, multi-stage can be different according to customer’s needs. Our planetary gearbox can match different motors such as stepper motor, brush motor, brushless motor, and DC motor.
