Mayr's ROBA-DS shaft couplings transmit the torque backlash-free and with high torsional rigidity. On the sizes up to 150 Newton meters, power transmission are going to extend its standard hubs for mounting the shafts by a radially divisible hub, for easy and fast installation, even in difficult ambient conditions.
The couplings are able to transmit high torques even at comparably small diameter, which makes them the roght shaft couplings for dynamic drive systems with high speeds. These couplings are made of steel and high-strength aluminum alloys.
The couplings compensate for radial, axial and angular shaft misalignments by means of the flexible disk packs. This way, they protect the bearings from unwanted wear and tear and prevent unnecessary downtimes and costs. In order to achieve backlash-free torque transmission, the disks in the fixing area are treated with a special blasting procedure. The ROBA-DS disk pack couplings are robust and reliable. They are temperature-resistant, wear- and maintenance-free and transmit the torque with very high torsional rigidity. Therefore, they are especially suited for applications in extreme ambient conditions.
