REB … DCO Series

REB … DCO Series

Product catalog summary

Overview: The document provides technical specifications and features of Pin and Bush Couplings REB … DCO, which are elastic and lubrication-free couplings used in various mechanical applications such as pump drives, belt drives, and ventilators.

Features:

Vertical/horizontal mounting capability.
Vibration absorption and progressive torsion spring properties due to pressurized bushings.
Fail-safe design in case of bushing failure.
Easy bushing replacement without disassembly of coupling halves.
Maintenance-free with no lubrication required.
Compliance with ATEX 2014/34/EU standards.

Bushing Materials:

NR 80 Shore-A: Natural rubber, hardness 80 ±5 Shore-A, temperature range -45 °C to +70 °C, color black.
PU 92 Shore-A: Polyurethane, hardness 92 ±5 Shore-A, temperature range -30 °C to +80 °C, color orange.
HTrans: Polyurethane, hardness 55 ±2 Shore-D, temperature range -30 °C to +120 °C, color white.

Specifications:

Coupling sizes range from 0105 to 2000, with varying maximum speeds, moments of inertia, and permissible misalignments.
Nominal torque and power ratings are provided for each coupling size, with details on maximum torque and alternating torque capabilities.
Performance data includes torsional stiffness and relative damping values.

Installation and Design:

Couplings can be momentarily overloaded at start-up by up to three times the nominal torque.
For vertical installation, consultation with RINGSPANN is recommended.
Finish bores should specify bore diameters for hubs A and B, with tolerances and keyways in accordance with DIN 6885, sheet 1.
