In a planetary gearbox, many teeth are engaged at once, that allows high speed reduction to be performed with relatively small gears and lower inertia reflected back to the motor. Having multiple teeth share the load also enables planetary gears to transmit high levels of torque. The combination of compact size, huge speed reduction and high torque tranny makes planetary gearboxes a favorite choice for space-constrained applications.
But planetary gearboxes perform involve some disadvantages. Their complexity in design and manufacturing tends to make them a far more expensive option than various other gearbox types. And precision manufacturing is really important for these gearboxes. If one planetary equipment is put closer to the sun gear compared to the others, imbalances in the planetary gears may appear, leading to premature wear and failing. Also, the compact footprint of planetary gears makes warmth dissipation more difficult, so applications that run at very high speed or experience continuous operation may require cooling.
When using a “standard” (i.electronic. inline) planetary gearbox, the motor and the driven equipment must be inline with each other, although manufacturers offer right-angle designs that include other gear sets (often bevel gears with helical the teeth) to provide an offset between your input and output.
