KD & KD2 Differential Speed Modulation Gearbox

The Tandler series KD speed modulation gearbox is used for inline shaft phasing or narrow range speed control. These gearboxes can be used as a 1:2 speed increaser or a 2:1 reducer, it depends on which shaft is used as the input, either the d1 or d2. Shaft phasing and narrow range speed control are affected by a worm gear mounted onto the bevel gear. The KD and KD2 are available in 6 different sizes.
