plot a gearbox in matlab

To plot a gearbox in Matlab, you can use the "gearbox" function of the Robotics System Toolbox. This function creates a visualization of a gearbox connected to a motor.

Here's an example code for plotting a simple gearbox with a motor:

main.m
% Define the gearbox parameters
module = 0.75;
N1 = 20;
N2 = 60;
P = 1000;
ratio = N2/N1;

% Create the gearbox object
gb = gearbox('gears',...
    {'cylindrical',module,N1,N2,'Steel';...
     'cylindrical',module,N1*N2,P,'Steel'});

% Create the motor object
motor = rigidBody('motor');
setFixedTransform(motor.Joint, trvec2tform([0,0,0.03]));

% Connect the gearbox to the motor
addBody(gb,motor,'motorshaft');
addBody(motor,gb,'gearboxinputshaft');

% Visualize the gearbox and motor
axes
show(gb)

This code creates a cylindrical gear with a module of 0.75, with 20 and 60 teeth, and a pitch diameter of 1000. The gear ratio is calculated as N2/N1, and the gearbox object is created using the gearbox function.

A motor is also created with the rigidBody function, and is connected to the gearbox with the addBody function. Finally, the gearbox and motor are visualized using the show and view functions.

This code will create a 3D visualization of the gearbox connected to the motor, which you can customize further to your needs.
