2 Motor Gearbox - Through Bore

Coming Soon

The 2 Motor Gearbox - Through Bore is compatible with the REV ION System. This two motor into one output gearbox allows the user to adjust the gear ratio by changing pinion and cluster gear (12:60, 18:54, 24:48, or 36:36). The output shaft is 1/2in Hex through bore, and output gears have a MAXSpline bore. The motor plate contains 2 Pairs of 2in pitch #10-32 tapped holes for mounting the REV Through Bore Encoder, and the output plate contains an array of holes for mounting to structure, as well as mounting as an input to the MAXPlanetary. The 5:1 Ratio (60:12) can be micro adjusted slightly larger by swapping the 12T pinion with 11T or 10T.
