Planetary Gearbox High Speed Gearbox High Power H.E. Gearbox

Planetary Gear Box


For very experienced model builders.
Getting its name from the way the gears rotate like the planets around the sun, the Planetary Gear Box is a precise, highquality gearbox with a RE-260 motor built into the gear box itself to add to its compactness. A wide range of gear ratios can be attained, and two kinds of crank arms are supplied for a wider range of functions. A highly versatile system for reduction of high RPM electric motors to high-torque low RPM applications. Often used in precision instruments because of the reliability and accuracy of the unit. The RC-260 motor included in this set utilizes carbon brushes for long motor life. RC-260 motor operates on 3 volts. Combining the gearboxes in various ways enables 8 different gear ratios (4:1, 5:1, 16:1, 20:1, 25:1, 80:1, 100:1, 400:1). At a gear ration of 400:1 and voltage of 3V, the gearbox produces a torque of about 15 kg. Pictorial instruction sheet included.
