Technical Data: Nominal torque ranges from 190 Nm to 1600 Nm, with peak torque up to 2400 Nm and ultimate torque up to 4800 Nm. The system supports maximum speeds from 4300 rpm to 9500 rpm.

Installation and Configuration: The ROBA®-DSM receiver connects to the strain sensor and supplies energy via the stator, featuring a 4-pole M12 plug for electrical connections and outputs signals for torque measurement.

Options and Variants: Various hub types and configurations are available, including key hubs, clamping ring hubs, and shrink disk hubs.

Safety and Overload Protection: The system includes options for overload protection, such as torque limiters and slip hubs, ensuring safety against overload damage.

Installation Examples: Examples include axial securement of key hubs, installation next to housing walls, and integration of measurement flanges.

Specifications: Split clamping hubs allow radial assembly/disassembly of ROBA®-DS couplings without misaligning the motor or gearbox. Vertical support is necessary for vertical or sloping installations with long intermediate sleeves.

Procedures: Direct coupling selection is based on known operational torques and temperature limits. Installation involves mounting hubs onto shafts, securing axially, and ensuring proper tensioning of screws.

Norms and Recommendations: Service factor fB and load classes are defined for various work machines. Permitted shaft misalignments are specified for different coupling types.

Key Data and Figures: Tables provide service factors, load classes, and transmittable torques for different hub sizes.

Critical Information: Ensure coupling nominal torque exceeds maximum operational torques. Maintain shaft misalignments within specified limits to ensure smooth operation.

Overview: The document provides technical specifications and guidelines for various types of hubs and couplings used in mechanical engineering applications.

Sections:

Specifications: Detailed specifications for shrink disk hubs, split clamping hubs, clamping hubs, and key hubs.
