SGgearchainwindup
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Kinematics and Frames
Introduced first in SolidGeometry 5.4, Creation date: 2024-05-12, Last change: 2025-09-15
returns a gear chain for a windup motor or a minimal size gear box - use SGgearstamp afterwards
Description
..written in the plane to Yokohama (ICRA 2024) and during the ICRA 2024
In contrast to SGgearchain, this function has been reimplemented, especially to windup motors or the use of only two fixed axis, which could require the adjustment of the gear module in each gear pairing.

height of gear
radius of axle == ATTENTION THERE IS THIS RADIUS AND "SHAFT" is ONLY FOR Gear #1

Syntax
[SG,m,f,SGW,CPLW]=SGgearchainwindup([mhr,z,"stack","shaft","debug","anime","backlash"])
Input Parameter
mhr: | | [m h r hr] of gear; default is [1 5 1.25 0] |
z: | | array of number of teeth |
"stack": | | if used the gears will be stacked as desired |
"shaft": | | if used this radius or CPL will be used for 1st and last |
"debug": | | if used the design will me shown |
"anime": | | if used the gearbox will be animated |
"backlash": | | if used the module is reduced to achieve a slot with the given value |
Output Parameter
SG: | | cell list of gears |
m: | | array of modules used |
f: | | ratio factor of the gears |
SGW: | | cell list of washer or spacer for the gears in SG |
CPLW: | | Contour of the shaft spacer SGW |
Examples
SGgearchainwindup([1 5],[45 9 34 10]); % Linear Chain
SGgearchainwindup([1 5],[45 9 34 10],'stack'); % Gear Box
[SG,m,f,SGW]=SGgearchainwindup(1,[39 11 39 11 39 11],'stack'); view(0,0)
SGgearchainrotate(SG,f,[pi/6],SGW)
SGW=SGW(~isemptycell(SGW))
