RDZ … DFO Series

RDZ … DFO Series

Product catalog summary

Overview: The document provides technical specifications and ordering information for Gear Couplings RDZ … DFO, which are torsionally rigid and feature single engagement gearing with lubrication. These couplings are designed for high nominal torques and are suitable for applications such as roll drives in the steel and paper industry, pumps, conveyors, fans, and blowers.

Features:

High nominal torques up to 391,500 Nm.
Compensation for axial and angular misalignments.
Compact design due to inside turned hubs.
High power density.
Compliance with ATEX 2014/34/EU standards.

Ordering Information: The document provides a detailed order example code, specifying the coupling design, size, type, material of the hub, and bore diameters for hubs A and B. It includes options for finish bored with keyway or rough bored designs.

Technical Specifications:

Nominal torque (TKN) and nominal power at 100 min-1 (PK100) are provided for various coupling sizes.
Maximum speed (nmax) and moment of inertia with max bore (JK) are listed.
Permissible misalignments include axial and angular specifications.

Dimensional Data: The document includes detailed dimensional data for each coupling size, including measurements for various diameters, lengths, and weights.

Additional Notes: Finish bores require specification of bore diameters for hubs A and B, with tolerances and keyways in accordance with DIN 6885, sheet 1. Different bore and keyway tolerances are available upon request, and bores are also available in inch sizes.
