In a planetary gearbox, many teeth are involved at once, which allows high speed reduction to be achieved with relatively small gears and lower inertia reflected back again to the electric motor. Having multiple teeth talk about the load also enables planetary gears to transmit high levels of torque. The combination of compact size, huge speed reduction and high torque transmission makes planetary gearboxes a favorite choice for space-constrained applications.
But planetary gearboxes perform have some disadvantages. Their complexity in design and manufacturing tends to make them a far more expensive answer than various other gearbox types. And precision production is extremely important for these gearboxes. If one planetary equipment is positioned closer to the sun gear than the others, imbalances in the planetary gears may appear, leading to premature wear and failure. Also, the compact footprint of planetary gears makes temperature dissipation more difficult, therefore applications that precision planetary gearbox operate at very high speed or encounter continuous procedure may require cooling.
When utilizing a “standard” (i.electronic. inline) planetary gearbox, the motor and the driven equipment must be inline with one another, although manufacturers provide right-angle designs that integrate other gear sets (often bevel gears with helical teeth) to supply an offset between your input and output.
