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!!??

, 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

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