CENTAFLEX® -E

Product catalog summary

Introduction
The document introduces the CENTAFLEX-E series of flexible shaft couplings by CENTA Power Transmission, now part of Rexnord. These couplings are designed for larger torque applications, known for their robustness and versatility, following a claw coupling design with compression-stressed rubber elements for flexibility and durability.

Specifications
The CENTAFLEX-E couplings come in 10 sizes, supporting nominal torques from 75 to 40,000 Nm. They handle misalignments with specified maximum angular, radial, and axial movements. Materials include steel for the claw part and GGG 50 or aluminum for the pocket part, with Perbunan (NBR) rubber buffers for oil and abrasion resistance.

Design and Features
The couplings have a simple, robust design for safe, compact operation, featuring generously dimensioned rubber elements for low stress and air cooling. They accommodate shaft misalignments without excessive reaction forces.

Installation and Operation
Installation is straightforward, even for flanged drives, with options for blind fitting. The couplings are fail-safe, dampening vibrations and shock loads, suitable for various operational conditions with service factors for demanding applications.

Types and Variations
There are three main types: Type 1 for connection to existing driving parts, Type 2 as a standard two-part shaft-to-shaft coupling, and Type 3 as a three-part coupling for easy maintenance. Each type has specific features, such as the number of claws, depending on the size.

Technical Data
Detailed technical data includes nominal and maximum torque, angle of twist, and maximum speed for each size, with guidelines for balancing at different speeds and transmitted power at various speeds.

Conclusion
The CENTAFLEX-E series offers a reliable solution for power transmission needs, emphasizing innovation and quality. Consulting with CENTA engineers is recommended for optimal coupling selection and performance.

Overview
This document provides technical specifications for the CENTAFLEX-E series, focusing on Types 2, 3, and 3-GZ, including dimensions, weight, mass moments of inertia, and order codes for various sizes.

Specifications

Type 2: Lists dimensions such as d3, d1, d2, L1, N1, N2, S±1, TA, L2, L4, weight, and mass moments of inertia for sizes 80 to 425, with specific order codes.
Type 3: Provides dimensions and specifications for sizes 160 to 560, with notes on larger bores available upon request.
Type 3-GZ: Includes additional dimensions such as d5 and C, specifying weight and mass moments of inertia for complete couplings without tubes and per 100mm tube length, sizes 160 to 560.

Procedures and Standards

All hubs are supplied pilot bored unless otherwise specified.
Tightening torque of bolts follows DIN 912 - 10.9 standards.
All data are subject to change without notice, and previous catalogs are rendered invalid by this document.

Applications
Examples include use in high-performance crane drives, torque limiters, shearpin hubs, and with brake discs.
