In a planetary gearbox, many teeth are engaged at once, which allows high speed reduction to be performed with fairly small gears and lower inertia reflected back again to the electric motor. Having multiple teeth discuss the load also enables planetary gears to transmit high degrees of torque. The combination of compact size, large speed decrease and high torque tranny 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 manufacturing is really important for these gearboxes. If one planetary gear is put closer to sunlight 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 heat dissipation more difficult, therefore applications that run at high speed or encounter continuous operation may require cooling.
When utilizing a “standard” (i.e. inline) planetary gearbox, the motor and the powered equipment should be inline with each other, although manufacturers offer right-angle designs that integrate other gear sets (often bevel gears with helical teeth) to provide an offset between the input and output.
