Please Let Me Know How Much You Like This (1 is very Bad - 10 is Excellent)




Space gear and rack 1e




Angle between pinion axle and rack moving direction is 0 deg. Normal module mn = 2 mm

Pinion:

- Helix angle B1 = 45 deg.

- Tooth number Z1 = 30

- Pitch circle dia. D1 = 84.85 mm Rack:

- Helical teeth, B2 = 45 deg.

1 pinion revolution makes rack move Pi.D1.cosB1/cosB2 = 266.56 mm

This drive resembles a screw-nut one when consider: the gear as a screw, the rack as a bar cut out longitudinally (axially) from a nut.
