Orange pinion:
- Helix angle B1 = 45 deg., right hand
Green pinion:
- Helix angle B1 = 45 deg., left hand
Wheels:
- Helix angle B1 = 45 deg., right hand
Angle between pinion and wheel axles for the green drive E = B1 - B2 = 0 deg.
Angle between pinion and wheel axles for the orange drive E = B1 + B2 = 90 deg.
Pay attention to the rotation directions of the wheels in each drive. They are opposite for the orange drive and of the same direction for the green drive.
