RDZ … EEO Series

Product catalog summary

Overview: The document provides technical specifications and details for Gear Couplings RDZ ... EEO, which are torsionally rigid with continuous sleeve and double engagement gearing. These couplings are designed to compensate for axial, radial, and angular misalignments and are suitable for both horizontal and vertical applications.

Features:

Compensation for misalignments.
Double engagement for smooth torque transmission.
Temperature range: -25 °C to +100 °C.
Low weight and low moments of inertia.
Maintenance-free due to steel and polyamide 6.6 construction.
Typical applications include hydraulics and pump drives.

Specifications:

Material of the hub: Steel STA.
Material of the sleeve: Polyamide 6.6 (PA66).
Finish bores with keyway, tolerance H7, keyway tolerance JS9.

Performance Data:

Nominal torque (TKN) and power (PK100) vary by coupling size.
Maximum speed and moment of inertia are specified for each size.
Permissible misalignments include axial, radial, and angular.

Dimensions: Detailed dimensions are provided for each coupling size, including minimum and maximum bore diameters, lengths, and weights.

Selection Guidelines: The selection of IEC standard motors is based on nominal torque at +30 °C, with a start-up factor SZ of 1 and a coefficient of impact SA/SL of 1. Detailed selection criteria are available in the technical information section.
