Datasheet RDL … DSO

Product catalog summary

Overview: The document provides technical specifications and ordering information for RDL DSO disc couplings, which are torsionally rigid and feature a single disc pack. These couplings are designed for high torque applications and are suitable for various industrial uses such as pumps, fans, and conveyor systems.

Key Features:

Nominal torques up to 18,700 Nm.
High torque capacity and backlash-free operation.
Compensation for axial and angular misalignments.
High torsional rigidity with low axial rigidity.
Temperature range from -20 °C to +280 °C.
Maintenance-free with proper alignment and long lifespan.
Compliance with ATEX 2014/34/EU standards.

Ordering Information: The document provides a detailed order example code for specifying the coupling design, size, type, material, and bore diameter for hubs A and B. It includes options for standard and increased maximum bore types, as well as finish bored with keyway or rough bored designs.

Technical Specifications:

Various coupling sizes with specific dimensions, weights, and performance metrics such as nominal torque, power, maximum speed, torsional stiffness, and moment of inertia.
Permissible misalignments include axial, radial, and angular, with specific tolerances provided.
Finish bores require specification of bore diameters with tolerances in accordance with DIN 6885, sheet 1.

Additional Notes:

Weight and torsional stiffness values are based on a combination of hub type 0 and hub type I with maximum bore diameters.
Radial misalignments are not permissible due to design constraints.
Options for taper bushes and larger couplings are available upon request.
For vertical installations, contact RINGSPANN for guidance.
