There may be many reasons for choosing planetary gear drive, but indeed, it is because of the advantages of planetary gear drive. A planetary gearbox is composed of a planet ring gear, a sun gear, a planet wheel shaft. Here are the advantages of planetary gear drive.
small volume, compact structure, large bearing capacity
Generally speaking, the outer size and mass of the planetary gear drive are smaller than those of the general types 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 shock and vibration resistance
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 transmission of planetary gear is stable, the ability to resist shock and vibration becomes strong, and the operation is more reliable.
Single-stage and multi-stage planetary gear trains can be customized according to customer’s needs. Our planetary gearbox can match different kinds of motors such as stepper motor, brushed motor, brushless motor and DC motor.
