In a planetary gearbox, many teeth are involved at once, that allows high speed decrease to be performed with fairly small gears and lower inertia reflected back to the engine. Having multiple teeth reveal the load also enables planetary gears to transmit high levels of torque. The mixture of compact size, large speed reduction and high torque transmitting makes planetary gearboxes a popular choice for space-constrained applications.
But planetary gearboxes perform have some disadvantages. Their complexity in design and manufacturing can make them a more expensive option than additional gearbox types. And precision production is really important for these gearboxes. If one planetary gear is put closer to the sun gear than the others, imbalances in the planetary gears may appear, leading to premature wear and failing. Also, the small footprint of planetary gears makes heat dissipation more difficult, so applications that run at high speed or encounter 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 integrate other gear sets (frequently bevel gears with helical teeth) to supply an offset between the input and output.
