SGwheelspiral

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Parametric Design
Introduced first in SolidGeometry 5.4, Creation date: 2024-07-02, Last change: 2025-09-15

returns a solid of a involute spoked wheel which limit a torque jump or spike

Description

This wheel should store overtorque energy in the involute spokes
will be improved by using a kerbkonus and a DIN 912 etc.
For a shaft slfit('t') is used for an axle slfit('c') is used

Syntax

[SG,CPL]=SGwheelspiral([R,H,n,A,shf,"DIN433","STL"])

Input Parameter

`R`:		[Ro Ro2 Ri]; default 15
`H`:		Heightand width of the spokes; default is [5 2]
`n`:		number of spokes; if n<0 the spokes are ccw
`A`:		'T30' if there is a need for a torx axle; Can also be a CPL
`shf`:		shaft==true [slfit('t')], axle=false [slfit('c')]; default is true
`"DIN433"`:		if used a pinring whaser of a DIN433 size is added
`"STL"`:		if used an STL file is written

Output Parameter

`SG`:		Solid Geometry
`CPL`:		CPL that was extruded

Examples

SGwheelspiral(15,[3 2],-3)
SGwheelspiral(15,[3 .8],-3,PLcircle(3),'DIN433')
SGwheelspiral(15,[3 2],3,'T30')   % String for Torx
SGwheelspiral(20,'','',PLwrench(6.4,6),true, 'stl','DIN433');    % For shafts
SGwheelspiral(20,'','',PLwrench(6.4,6),false, 'stl','DIN433');   % For axes
