Drawing of a worm gear

Drawing of a worm gear

Drawing of a worm gear

(OP)
Hi there
Not to sure on how to proceed on theis I have a worm gear with a 4 deg helix ( actually not a spring like helix) Just the 2 end faces are offset from each other by 4 deg in the z plane
Sort of like twisting each end
Its a shaft with the gear in the middle  and the teeth of the gear are at a 4 deg to the axis of the shaft,,,

Anyway I have drawn the tooth profile arrayed them around a circle and can extrude to give a straight ie not at an angle to the shaft axis ...
How can I achieve this tooth offset ,,,I tried rotating faces but it woul only pick the tooth flank face ...

Any Ideas
Extrude the individual tooth and array!!??

Try searching here for threads on "threads" (as in screw threads).  Whatever help you find there will apply to your case.

Hi there no didnt help ,,,I travel through but couldnt find anything
, strangely I can draw the worm ( helix lisp ) but and the worm gear as a straight tooth ie not at an angle to its ( the shaft) axis
but I need to draw the worm gear teeth at an 4 deg angle to ist axis, my plan was to revolve one face ,,,but it flopped ,,,hence the question

Extrude one tooth only, in a Z axis that's rotated 4 degrees from the shaft axis.

Go back to the regular coordinate system, and array the solid tooth around the pitch circle.
