Gear and rack characteristics of large modulus CNC lathes

1) The gear meshing with the rack can be spur gear or helical gear,

Characteristic of a helical gear and having a spur gear or

2) Rack and gear drive, is to turn the rotation into a straight line movement or the movement into rotation

3) The rack is formed when the diameter of the gear is infinite

4, pinion two axes in space can be parallel to each other, interwoven, vertical

5, the pinion rotation direction can be the same, can also be opposite

6, the pinion helix Angle can be equal, but also can not be equal greatly

Large modulus CNC lathe becomes worm gear when the helical Angle of the small gear is large to a certain level.
