In a planetary gearbox, many teeth are involved at once, that allows high speed reduction to be precision planetary gearbox achieved with relatively small gears and lower inertia reflected back again to the engine. Having multiple teeth talk about the load also enables planetary gears to transmit high levels of torque. The combination of compact size, large speed reduction and high torque transmission makes planetary gearboxes a favorite choice for space-constrained applications.
But planetary gearboxes do have some disadvantages. Their complexity in design and manufacturing can make them a far more expensive solution than additional gearbox types. And precision production 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, resulting in premature wear and failing. Also, the compact footprint of planetary gears makes warmth dissipation more difficult, therefore applications that operate at high speed or encounter continuous operation may require cooling.
When using a “standard” (i.electronic. inline) planetary gearbox, the motor and the powered equipment should be inline with one another, although manufacturers provide right-angle designs that integrate other gear sets (often bevel gears with helical tooth) to supply an offset between the input and output.
