looking for an equation drive helix (helical cam) example

am not having much luck defining a helical curve using an equation. the cam profile follows this equation

but i cannot figure out how to generate the helix in SW. have tried variable pitch helix and equation driven curve but no luck.

Anyone have an example part to share so i can see how its done?

 

here is a table of the height vs angle.

t, degy, in
00
15-3.6773
30-6.8744
45-9.6454
60-12.0333
75-14.0801
90-15.8191
105-17.2801
120-18.4889
135-19.4684
150-20.2386
165-20.8175
180-21.2207

 

 

Thanks!


Dave
