SGgearDINrot
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - ENG-Components
Introduced first in SolidGeometry 4.3, Creation date: 2018-10-08, Last change: 2025-09-14
Calculate a gear with the count from 9.12 to 48; for internal and external gears
Description
This function modified for SG-Lib 5.3 creates also Base-Frame B, Gap-Frame FG and Tooth-Frame FT by a given angle. A chain of geras can be linked by using the SGtransrelSG concept by aligning "FG" and "FT". It is possible to give a desired rotation angle for the following toth frame but this angle has a quantization of 2*pi/z.
In case of linking just 2 gears, the angle may not by as important, but as soon as there is 3rd gear of a mechanism designed the correct angle has to be used

Syntax
[SG,al]=SGgearDINrot([m,z,R,h,tig,al,"space"])
Input Parameter
m: | | modul; negativ values for internal gears; 0 for testing |
z: | | number of teeth |
R: | | radius for a shaft/axle or CPL for inner contour |
h: | | height of the gear; or [zmin zmax slot]; Base = eye(4); [h(1)+slot h(2)-slot-space(1)]
|
tig: | | false - gap; true = tooth; at zero line; default is false; |
al: | | desired angle for the following tooth frame |
"space": | | [height and width of spacer] that is always on the upper side default is [0 1.2] |
Output Parameter
SG: | | Solid Geometry |
al: | | angle in steps of 2*pi/z |
