Planetary Reduction Drive

The planetary reduction drive is based on an classic but ingenious design. It is based on a system of ball bearings rolling between two surfaces while housed within a rotating bushing.

The planetary reduction drive is often used to enhance the fine-tuning control of a variable capacitor.

For most applications:

A knob is attached to input shaft

The variable capacitor's shaft is fastened into the planetary drive's output shaft coupler

Vernier dial is attached to unit's optional dial flange

The drive's mounting bracket is attached to stationary housing or cabinet

Now when the knob is turned through one complete rotation, the vernier dial and the capacitor's shaft rotate one-sixth of a rotation. Thus, a very small change in capacitance does not require extremely fine motor skills on the part of the operator.
