RDZ … DTO Series

RDZ … DTO Series

Product catalog summary

Overview: The document provides technical specifications and features of Gear Couplings RDZ … DTO, which are torsionally rigid and designed for double engagement gearing with lubrication. These couplings are suitable for high nominal torques and have a high misalignment capability, making them ideal for various industrial applications.

Features:

High nominal torques up to 391,500 Nm.
Capability to compensate for axial, radial, and angular misalignments.
Double engagement allows smooth torque transmission.
Compact design due to inside turned hubs.
Compliance with AGMA standards up to coupling size 0090.
High power density and compliance with ATEX 2014/34/EU.
Typical applications include roll drives in the steel and paper industry, pumps, conveyors, fans, and blowers.

Specifications:

Order example code includes coupling design, size, type, material, and bore diameter specifications.
Finish bores require specification of bore diameter for hubs A and B, with tolerance H7 and keyways in accordance with DIN 6885, sheet 1.
Keyway tolerance is JS9, with different bore and keyway tolerances available upon request.
Couplings larger than frame size 0100 are available upon request.

Technical Data:

Tables provide detailed dimensions, weights, and performance metrics for various coupling sizes, including nominal torque, power, maximum speed, moment of inertia, and permissible misalignments.
Data includes pilot bore, bore diameter, and weight with maximum bore for each coupling size.

Additional Notes:

Bores are also available in inch sizes.
Minimum necessary space to align the shafts is specified.
