In a planetary gearbox, many teeth are involved at once, which allows high speed reduction to be achieved with fairly 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, large speed reduction and high torque tranny makes planetary gearboxes a popular choice for space-constrained applications.
But planetary gearboxes perform have some disadvantages. Their complexity in style and manufacturing can 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 put closer to sunlight gear than the others, imbalances in the planetary gears can occur, resulting in premature wear and failing. Also, the small footprint of planetary gears makes heat dissipation more difficult, so applications that run at very high speed or experience continuous operation 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 incorporate other gear sets (often bevel gears with helical the teeth) to provide an offset between the input and output.
