Reliable couplings and torque limiters for high-speed applications
Drive axles in the high speed range require reliable couplings and torque limiters for overload protection and to compensate for shaft misalignment. At the expo, Mayr Power Transmission will present its new developments for test bench technology.
Based on the proven Roba DS steel disk pack coupling, Mayr Power Transmission has developed a weight-optimized aluminum version. Compared with the steel version, the outer diameter of this new design has been reduced by up to 10mm; the mass and mass inertia range from 40% to 60% of the steel version, depending on the design and size. The performance density remains unchanged.
The coupling is tailored to meet the requirements of high-speed applications, for example in the field of test bench technology. Shaft couplings are a crucial accessory in test benches because they minimize the disturbance variables acting on the measuring flange. These so-called parasitic forces are often caused by misalignment in the drivetrain. Offsets between the input and output sides occur in almost all applications. Shaft couplings are therefore used together with the measuring flange.
However, reliable overload protection at high speeds is also crucial for high-speed applications. If the torque in a test bench exceeds the limit value set on the torque limiter, the clutch disengages and separates the input and output within fractions of a second. At worst, the measuring shaft must be recalibrated after an overload, but the safety clutch reliably prevents expensive damage to the drivetrain or test specimen. The EAS HSE safety clutches from Mayr Power Transmission transmit torques backlash-free and with high torsional rigidity. They are also compact and have a low mass moment of inertia with a high power density.
