Belt width b [cm]

\begin{align}
b& = {F_U \over {z_e \cdot F_{Uspez}}} && F_U [N] \\
b& = {100 \cdot M \over {z_1 \cdot z_e \cdot M_{spez}}} && M [Nm]\\
b& = {1000 \cdot P \over {z_1 \cdot z_e  \cdot P_{spez}}} && P [kW]
\end{align}

Load bearing characteristics of the drive

when belt width [cm] is

\begin{align}
F_{U}& = {F_{Uspez} \cdot z_e \cdot b} &&[N]\\
M& = {{M_{spez} \cdot z_1 \cdot z_e \cdot b} \over {100}} &&[Nm]\\
P& = {{P_{spez} \cdot z_1 \cdot z_e \cdot b} \over {1000}} &&[kW]
\end{align}

Number of teeth in mesh

\begin{align}
 z_{e max}& = {12}\\
 z_e& = {{{z_1} \over {180}} \cdot \arccos{{t \cdot (z_2 - z_1)} \over {2\pi \cdot a}}}\\
 \end{align}
