Tengo la intención de definir el primer círculo establecido en x = 0 e y = 0 y los otros círculos que dependen de él.
Tendré que cambiar los diámetros de estos círculos unas cuantas veces, para que los centros de estos cambien.
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\draw[very thick] (0mm,0mm) circle (10mm/2);
\draw[very thick] (20mm,0mm) circle (30mm/2);
\draw[very thick] (43mm,0mm) circle (25mm/2);
\draw[very thick] (43mm,0mm) circle (16mm/2);
\draw[very thick] (66.5mm,0mm) circle (22mm/2);
\end{tikzpicture}
\end{document}
¿Cuál sería la mejor manera de optimizar este dibujo?

Primera versión
Solo por diversión.

\path (c) ++({#1/2 + #2/2},0) coordinate (c);
\path[#3] (c) circle (#2/2);
},
% a styled chain of gears
gearbox/chain/.code 2 args={% start point, list of gears
\coordinate (c) at #1;
\foreach \diameter/\typeofgear/\mystyle
[remember=\diameter as \prevdiameter (initially 0)] in {#2}{

}
},
}
\begin{document}

Puedes usarlo coordinatespara los centros de los círculos. Puede utilizar muchas derivaciones al definirlas. Aquí he definido algunos diámetros para los círculos que se pueden cambiar. No es el panorama completo, pero podría ser un buen comienzo.
\documentclass[border=5mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}[x=1mm,y=1mm,>=latex]
\newcommand\Di{10} %% Diamater of left circle
\newcommand\Dii{30} %% Diameter of next circle
\newcommand\Diiia{16} %% Diamater of inner circle
\newcommand\Diiib{25} %% Diameter of outer circle
\newcommand\Div{22} %% Diameter of right circle
\coordinate (C1) at (0,0);
\coordinate (C2) at (\Di/2+\Dii/2,0);
\coordinate (C3) at ($(C2)+(\Dii/2+\Diiia/2,0)$);
\coordinate (C4) at ($(C3)+(\Diiib/2+\Div/2,0)$);
%%
\draw[thick] (C1) circle (\Di/2);
\draw[thick] (C3) circle (\Diiia/2);
\draw[thick] (C3) circle (\Diiib/2);
\draw[fill=white,thick] (C2) circle (\Dii/2);
\draw[thick] (C4) circle (\Div/2);
%%
\draw[gray!70] ($(C1)+(0,-30)$) -- +(0,30+\Di/2+3) node[pos=0,left,rotate=90,black]{0};
\pgfmathparse{\Di/2+\Dii/2}\edef\res{\pgfmathresult}
\draw[gray!70] ($(C2)+(0,-30)$) -- +(0,30+\Dii/2+3) node[pos=0,left,rotate=90,black]{\res};
\pgfmathparse{\res+\Dii/2+\Diiia/2}\edef\res{\pgfmathresult}
\draw[gray!70] ($(C3)+(0,-30)$) -- +(0,30+\Diiib/2+3) node[pos=0,left,rotate=90,black]{\res};
\pgfmathparse{\res+\Diiib/2+\Div/2}\edef\res{\pgfmathresult}
\draw[gray!70] ($(C4)+(0,-30)$) -- +(0,30+\Div/2+3) node[pos=0,left,rotate=90,black]{\res};
\draw[gray!70] ($(C1)+(-\Di/2-3,0)$) -- ($(C4)+(\Div/2+3,0)$);
%%
\draw (C1 |- {(0,-28)}) circle (1pt);
\draw[->] (C1 |- {(0,-28)}) -- (C2 |- {(0,-28)});
\draw[->] (C2 |- {(0,-28)}) -- (C3 |- {(0,-28)});
\draw[->] (C3 |- {(0,-28)}) -- (C4 |- {(0,-28)});

Para agregar los diámetros, cargue \usepackage{wasysym}y agregue lo siguiente a la imagen:
\newcommand\DrawDiameter[3]{% {<center>}{<angle>}{<diameter>}
\ifnum#2<90\relax
\draw[->] (#1) +(#2:#3/2+15) -- +(#2:#3/2) node[anchor=south east,pos=0,rotate=#2]{\diameter#3};
\else
\draw[->] (#1) +(#2:#3/2+15) -- +(#2:#3/2) node[anchor=south west,pos=0,rotate=180+#2]{\diameter#3};
\fi
\draw[gray!70] (#1) +(#2:#3/2) -- +(180+#2:#3/2);
\draw[<-] (#1) ++(180+#2:#3/2) -- +(180+#2:5);
}
\DrawDiameter{C1}{110}{\Di}
\DrawDiameter{C2}{110}{\Dii}
\DrawDiameter{C3}{110}{\Diiia}
\DrawDiameter{C3}{70}{\Diiib}
\DrawDiameter{C4}{110}{\Div}
