Features of planetary gearboxes

Compared with ordinary gear drives, planetary gearbox transmissions have many features. The main features of planetary gear transmission are as follows.

1. Small size, small mass, compact structure and large load capacity. It is a common shaft due to the drive and power distribution of the planetary gearbox as well as the transmission of the center wheel and the rational application of the internal meshing gear.

2. Drive efficiency. This is due to the symmetry of the planetary gear drive structure. It is well known that there are many kinds of planetary gearboxes. The reaction force of the split pin wheel and the rotation arm can be balanced, which is beneficial to the transmission efficiency. If the selected drive type is suitable and the structure is reasonable.

3. Large drive comparison. The drive is larger than the planetary gearbox, still can maintain the characteristics of compact structure, small size and volume, but also to achieve synthetic decomposition motion, to achieve a variety of complex movements. As long as the type of planetary gearbox and distribution scheme is properly selected, planetary gears can be realized by synthesis and motion decomposition, and variables can be used to obtain a large number of gear ratios.

4. The planetary gearbox uses the same planetary wheels with uniform distribution of the center wheel, so that the planetary wheels and force balance arms move simultaneously to make the planetary gearbox stable. At the same time, the teeth are added, the planetary gears move stably, the stronger the impact resistance and vibration, the more reliable the work.
