K1 CONTI® SYNCHROFLEX polyurethane timing belt

Version:

  • Single-sided
  • Notched profile with metric pitch.
  • The technical data refer to the high performance casting polyurethane and steel tension members
  • Belt lengths < 100mm: application of casting polyurethane DADU 9311, colour yellow
  • Preferred belt widths: 4, 6, 10 mm

On request:

  • Double-sided; with flights on the back of the belt; with reinforced back of the belt; polyurethane special materials; further tension member versions (steel, textile tension member); antistatic, coloured, mechanical reworked
  • In-between widths, larger widths and other dimensions

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]

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}}}\\
