Counter-Rotating T Style Bevel Gearboxes
Ondrives.US’ counter-rotating gearboxes are T style bevel gearbox systems with two output shafts on the same axis and one input shaft at 90° from both outputs. Similar to our standard T style bevel gearboxes, our counter-rotating gear drives are unique in that the two output shafts rotate in opposite directions simultaneously.
Our counter-rotating gearboxes feature single piece machined aluminum housings, three hardened steel bevel gears, and three sets of radial ball bearings.
Counter-Rotating Gearboxes in 1:1 & 2:1 Ratios
We offer counter-rotating T style bevel gearboxes in 1:1 and 2:1 gear ratios, with six shaft size options; housing sizes increase in proportion with shaft size. Our smallest counter-rotating gear reducers have 5mm diameter shafts and provide maximum torque output of 1.77Nm; the largest counter-rotating gear drives we offer feature 25mm shafts and provide torque output up to 128Nm.

Another valuable reference, Inertia and the Use of Inertia Figures offers a formula for dealing with inertia in gearbox selection.
