AT10 GEN III CONTI® SYNCHROFLEX polyurethane timing belt
Standard version:
- Single-sided
- High performance polyurethane mixture (colour: red) for higher performance, longer longevity and better temperature resistance
- Bifilar design of the steel tension members for optimised straight belt run
- Higher packing density of tension members for a higher overall stiffness
- High performance AT profile with metric pitch and trapezoidal teeth
- Preferred belt widths: 16, 25, 32, 50, 75, 100, 150 mm
On request:
- In-between widths, larger widths and other dimensions are possible
- With profiles on the back of the belt
Please consider our warranty.
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}& = {16}\\
z_e& = {{{z_1} \over {180}} \cdot \arccos{{t \cdot (z_2 - z_1)} \over {2\pi \cdot a}}}\\
\end{align}
