What is a Planetary Gearbox?

A Planetary Gearbox is a type of gearbox where the input and output have the same centre of rotation, meaning the centre of one gear revolves around the centre of the other. The input shaft and the output shaft of a planetary gearbox are aligned.

How does a Planetary Gearbox work?

A Planetary Gearbox works by using a gear arrangement in which three planet gears rotate about a pinion, or sun gear as it is also known. The planet gears orbit inside an internal gear which is cut into the inner circumference of the gearhead body. The construction of the gearhead is rigid which increases its torsional rigidity.

Planet gears share the load attached to the output shaft with an arrangement that gives planetary gearheads a higher load capacity. As it is feasible to have a quantity of gears within a confined space, high ratios can be achieved.

What is a Planetary Gearbox used for?

Planetary Gearboxes are ideal for use on high-precision, motion control applications that require a high torque-to-volume ratio, quiet operation, low backlash and high torsional stiffness. Uses include:
