High-speed torque limiters The airbag for your test stands Torque limiters by mayr ® power transmission protect test stands reliably against expensive overload damages. They save costs and increase productivity. In comparison to standard torque limiters on the market, the EAS®-HSC and EAS®-HSE test stand clutches feature numerous special technical details. What can be seen at first glance is the exceptionally compact design of the clutches. A high performance density reduces the rotating masses and has a positive effect on the running smoothness and machine dynamics. The basic prerequisite...

EAS®-HSC torque limiting clutch Torque range: 5 Nm - 1.000 Nm Speeds of up to 12000 rpm Perfect for all fast-running drives Due to their excellent characteristics, EAS®-HSC and EAS®-HSE torque limiters are the best choice not only for test stands, but also for other fast-running drives. • Positive locking overload clutch • Complete separation • Synchronous re-engagement • Balanced when completely installed • Diverse mounting variations • High torsional rigidity • High performance density • Low mass moment of inertia (up to 20.000 rpm possible as special design) The detailed Product...

Couplings for torque transducers Backlash-free shaft coupling for accurate measuring results Torque measuring flanges represent the heart of modern test stands. Even in high-performance and high-speed applications, they provide accurate and reliable data. However, the measurement result is only as good as the shaft misalignment compensation coupling used, as shaft couplings represent a decisively important component in order to minimise the interference parameters affecting the measuring flange. Such interference parameters frequently occur due to alignment errors on the drive line. For...

Tailored to the requirements of test stands The couplings are particularly robust and resistant, and are characterised in addition to their high running smoothness and low mass moment of inertia through a high balance quality. The connection of the ROBA®-DS couplings and the measuring flanges to the drive train generally takes place backlash-free via high-quality shrink disk hubs. Various standard and high-speed constructional designs especially tailored to the various test stand requirements and flexible combination possibilities permit the integration of measuring flanges in almost every...

ROBA®-DS servo couplings High performance in a compact package Small dimensions, small installation space requirements, reduced weight and low mass moments of inertia – the ROBA®-DS servo couplings convince through their high performance density. They are able to transmit high torques even with a comparatively small diameter and are therefore the ideal shaft couplings for dynamic drive systems with high speeds. The basis for this extremely compact construction design is its execution in steel and highstrength aluminium alloys. Through the elastic disk packs, the couplings compensate for...

ROBA®-DS disk pack couplings High-performance shaft couplings for high torques The ROBA®-DS disk pack couplings by mayr ® power transmission are robust, reliable and temperature-resistant. They are therefore particularly suitable for use in extreme ambient conditions. In addition, the ROBA®-DS couplings are wear-free, meaning that they reduce the required maintenance effort to a minimum. mayr ® power transmission has equipped the large ROBA®-DS disk pack couplings for high torques, i.e. with a nominal torque range from 22,000 to 110,000 Nm, with an installation-friendly, positive locking...
