Normal module mn = 2 mm
Input worm:
- Number of starts Z = 2
- Lead Angle LA = 10.81 deg.
- Direction of thread: right hand
- Pitch circle dia. D = 20 mm
Gear:
- Helix angle B2 = 30 deg., right hand
- Tooth number Z2 = 30
- Pitch circle dia. D2 = 69.28 mm
Angle between worm and gear axes is L = 40.81 deg.
Velocity ratio: i = Z2/Z1 = 15
