When designing this range of gearbox, STM technicians decided to project one single body to include all gears.
This solution allows an efficient heat dissipation as well as a high housing rigidity and application easiness.
Efficiency will then be mostly positively improved but also reliability and highest transmittable torque.
The compromise cost/performances is particularly centered in the middle range reduction ratios.
The CB series of Helical Worm gear box has added a new dimension to the worm style gear box. With the addition of a helical pre-stage incorporated inside the gear case greater flexibility can now be achieved with increases in efficiency and a wider range of ratios up to 400:1 making this an extremely versatile gearbox.
