Datasheet REK … DCO

Product catalog summary

Overview: The document provides detailed specifications and guidelines for Jaw Couplings REK ... DCO, designed for dynamic applications with curved jaws. These couplings are elastic and compensate for misalignments while absorbing vibrations. They are maintenance-free and comply with ATEX 2014/34/EU standards, making them suitable for various applications such as pump drives and conveyor belts.

Specifications:

Material Options: Steel, Cast Iron, Aluminum.
Spider Materials: Polyurethane with hardness options of 92, 95 Shore-A, and 65 Shore-D.
Temperature Range: -30°C to +120°C depending on the spider type.
Design Types: Standard (0), Increased Max Bore (I), Extended Increased Max Bore (II).

Performance Data:

Nominal Torque (TKN) and Maximum Torque (TK max) values are provided for different coupling sizes.
Permissible Misalignments: Axial, Radial, and Angular values are specified.
Max Speed: Varies by material and coupling size, with steel hubs supporting higher speeds.

Installation and Maintenance:

Finish bores should specify bore diameter for hubs A and B with H7 tolerance.
Keyways are in accordance with DIN 6885, sheet 1, with JS9 tolerance.
No lubrication is necessary, ensuring a maintenance-free operation.

Applications: Typical applications include pump drives, ventilator drives, crane trolleys, machine tools, and conveyor belts.

Additional Information: The document includes tables for weights, moments of inertia, and performance data for various coupling sizes. It also provides guidelines for selecting IEC standard motors based on coupling size and motor power requirements.
