参数 \newcommand tikz

我需要制作一系列齿轮系，我已经习惯了\newcommand参数化齿轮。我确信可以以更有效的方式做到这一点，如果有人能帮我编写更好的代码，那将很有帮助。这比逐行完成要好得多。

\documentclass[border=3mm,tikz]{standalone}

\usetikzlibrary{patterns,patterns.meta}


% inputs are x, y , diameter of gear
\newcommand{\mygear}[3]{
\draw[very thick] (#1-0,#2+#3/2+0.1) -- (#1-0,#2+0.1);
\draw[very thick] (#1-0.1,#2+#3/2+0.1) -- (#1+0.1,#2+#3/2+0.1);
\draw[very thick] (#1-0.2,#2+0.1) -- (#1+0.2,#2+0.1);
% center of gear
\draw[very thick] (#1-0.2,#2-0.1) -- (#1+0.2,#2-0.1);
\draw[very thick] (#1-0.1,#2-#3/2-0.1) -- (#1+0.1,#2-#3/2-0.1);
\draw[very thick] (#1-0,#2-#3/2-0.1) -- (#1-0,#2-0.1);
}

\begin{document}

\begin{tikzpicture}[blue]

\mygear{1}{5}{2}
\mygear{1}{7.8}{3}
\mygear{2}{5.8}{2}
\mygear{2}{3}{3}

\draw (1,5) -- (1.5,5) |- (2,5.8);
\draw (1,7.8) -- (3,7.8) -- (3,3) -| (2,3);



    \end{tikzpicture}
\end{document}

您的问题无法得到这样的回答，因为使用哪种方法取决于个人喜好。您可以尝试使用图片，这样可以轻松应用样式，并很好地融入 Ti钾我认为 Z 环境：

\documentclass[border=3mm,tikz]{standalone}

\tikzset{
    gear upper/.style={
        very thick
    },
    gear lower/.style={
        very thick
    },
    pics/gear/.style={code={
        \draw[pic actions, gear upper] 
            (0,#1/2+0.1) -- (0,0.1)
            (-0.1,#1/2+0.1) -- (0.1,#1/2+0.1)
            (-0.2,0.1) -- (0.2,0.1);
        % center of gear
        \draw[pic actions, gear lower] 
            (-0.2,-0.1) -- (0.2,-0.1)
            (-0.1,-#1/2-0.1) -- (0.1,-#1/2-0.1)
            (-0,-#1/2-0.1) -- (0,-0.1);
    }}
}

\begin{document}
\begin{tikzpicture}[blue]

\pic at (1,5) {gear={2}};
\pic at (1,7.8) {gear={3}};
\pic[red] at (2,5.8) {gear={2}};
\pic[red, gear lower/.append style={densely dotted}] at (2,3) {gear={3}};

\draw (1,5) -- (1.5,5) |- (2,5.8);
\draw (1,7.8) -- (3,7.8) -- (3,3) -| (2,3);

\end{tikzpicture}
\end{document}

在此处输入图片描述

使用这种方法，您甚至可以向图片添加一个坐标，以后可以将其用作锚点：

\documentclass[border=3mm,tikz]{standalone}

\tikzset{
    gear upper/.style={
        very thick
    },
    gear lower/.style={
        very thick
    },
    pics/gear/.style={code={
        \draw[pic actions, gear upper] 
            (0,#1/2+0.1) -- (0,0.1)
            (-0.1,#1/2+0.1) -- (0.1,#1/2+0.1)
            (-0.2,0.1) -- (0.2,0.1);
        % center of gear
        \coordinate (-center) at (0,0);
        \draw[pic actions, gear lower] 
            (-0.2,-0.1) -- (0.2,-0.1)
            (-0.1,-#1/2-0.1) -- (0.1,-#1/2-0.1)
            (0,-#1/2-0.1) -- (0,-0.1);
    }}
}

\begin{document}
\begin{tikzpicture}[blue]

\pic (gear-1) at (1,5) {gear={2}};
\pic (gear-2) at (1,7.8) {gear={3}};
\pic[red] (gear-3) at (2,5.8) {gear={2}};
\pic[red, gear lower/.append style={densely dotted}] (gear-4) at (2,3) {gear={3}};

\draw (gear-1-center) -- ++(0.5,0) |- (gear-3-center);
\draw (gear-2-center) -- ++(2,0) |- (gear-4-center);

\end{tikzpicture}
\end{document}

输出与上面相同。
