CENTADISC-M

Product catalog summary

Introduction
The CENTADISC-M is a patented flexible shaft system by CENTA, known for its innovative design and reliability. It features a double cardanic system with tandem membrane couplings, providing torsional stiffness and compensating for axial, radial, and angular misalignments. The system is wear-free, offering high flexibility with low internal stress.

Key Features

High axial and angular flexibility, converting radial misalignments into angular ones.
Compensation for substantial misalignments with low reacting forces.
Economical design with compact dimensions, low weight, and high temperature resistance.
Maintenance-free and easy to assemble, with all components radially accessible.
Modular design allowing easy component exchange.

Applications
Suitable for ship propulsion, pump drives, cooling tower drives, printing machines, and general engineering.

Types

CENTADISC-M-S: Features a thin wall steel tube, either welded or as one piece for short lengths.
CENTADISC-M-C: Utilizes a carbon fiber reinforced composite tube, offering low weight, corrosion resistance, and high critical speed.

Technical Data
The system supports a torque range from 12.5 to 160 kNm, with higher and lower torques available on request. It allows for radial and angular misalignments, with specific values provided for continuous duty. The design ensures that axial misalignment is mostly static, while angular misalignment is dynamic.

Dimensions and Masses
Details on dimensions, weights, and inertias are provided, with specific values for steel tubes. Composite tube values are available on request. The design allows for customization of membrane diameters and middle section lengths.

Special Types

Short version with hubs inside the tube, not allowing radial exchange.
Combination with torsionally soft CENTAX couplings for damping torsional vibrations, suitable for diesel engines on soft mounts.

System Engineering
CENTA provides complete shaft systems, including couplings, clutches, bearings, and seals, with necessary calculations for torsional vibration and critical speed. These systems are suitable for connecting diesel engines with gear units and other driven units, especially in ship propulsion.

Overview
The document details CENTA's capabilities in developing complete drive systems, including the calculation of torsional vibrations and critical bending speeds of shafts and components. It highlights the company's expertise in delivering perfectly coordinated components such as flanges, bearings, seals, and shaft connections.

Specifications
CENTA offers drive systems with shaft lengths up to 25 meters and torque capacities up to 700 kNm. The systems include elastic CENTA couplings, carbon fiber shafts, and all necessary components, aiming to provide reliable, cost-effective, technically elegant, and weight-optimized solutions that are vibration and noise-dampening.

The patented design of the CENTA-membrane couplings has proven its reliability on numerous applications with CENTAX-couplings for several years. The arrangement of 2 sets of such membranes with a spacer provides a flexible and wearfree double cardanic system with outstanding advantages and it is marketed under the registered tradename CENTADISC-M. Die patentierte Konstruktion der CENTA MembranKupplungen hat sich seit Jahren an zahlreichen CENTAX-Kupplungen bewährt. Die Anordnung von zwei Satz dieser Tandem-Membranen mit einem Zwischenrohr ergibt ein drehsteifes, verlagerungsfähiges, verschleiss...

CENTADISC-M-S mit eingeschweißtem, dünnwandigem Zwischenrohr aus Stahl oder einteiligem Mittelteil aus Stahl bei kleiner Baulänge. with thin wall steel tube, either welded to the end pieces or made as one piece for short lengths. CENTADISC-M-C with tube made from carbon fibre reinforced composites. The composite tubes have the following advantages: very low weight, corrosion resistance, high critical speed. Therefore larger distances can be spanned (up to 10 metres) and/or higher speeds can be accepted. With intermediate bearings shaft lines of any length can be provided. On such long shaft lines...
