       Selecting torque limiters and



       couplings for high speed tasks



       Drive axes in the high-speed range require reliable clutches and couplings, because
       if collisions occur at high speeds, they can cause severe damage. But couplings do
       not only provide overload protection. Dynamic and high-precision shaft misalignment
       compensation couplings also create the prerequisites for exact measurement results.

       The experts at Mayr guide us through product selection for these applications.
             he classic speeds of up to 1,500 rpm have
             long been outdated. In most industries, an
             increasing demand for dynamic, fast-
       Trotating drive axes can be observed. And
       in particular in the measurement and test stand
       technology, the solutions must also be highly
       precise. Furthermore, at the high speeds, many
       users pay particular attention to the safety and
       reliability of the drive line. After all, here collisions
       can cause serious injuries or damage materials.
         For this purpose, mechanical torque limiting
       clutches are used to protect the test pieces and
       measuring units. These open the drive line and   addition, it is important that the clutches transmit
