Product catalog summary

Introduction
Universal joint shafts are essential for transmitting power from diesel engines to non-flange-mounted units, often encountering high vibratory torques due to torsional vibrations. The CENTAX-V series intermediate couplings mitigate these issues by offering high torsional elasticity and damping, effectively shifting dangerous resonances below operating speeds and reducing vibratory torque.

Advantages and Characteristics
CENTAX-V couplings are characterized by linear stiffness, robust flexible elements, and internal ventilation for heat dissipation. They are available in various designs with flywheel adaptors and hubs, offering maintenance-free operation and economical pricing. These couplings can accommodate a maximum angular misalignment of 9 degrees and are available with classification certificates upon request.

Applications
These couplings are utilized in construction equipment, ship propulsion drives, locomotives, and pumping sets, ensuring reliable connections between engines and transmission components.

Sizes and Materials
The CENTAX-V series includes 16 standard sizes, covering torque ranges from 230 to 44,000 Nm. The flexible elements are crafted from high-quality natural rubber, while the flanges are made from precision high-strength steel, suitable for high rotational speeds.

Selection and Safety
Initial coupling selection is based on transmitted torque, with final selection requiring a torsional analysis. Safety guards are not included, and adequate clearance is necessary due to potential increases in the rubber element's diameter.

Standard and Special Series
The catalog outlines various series such as VFA, VFB, VFM, and VFS, each tailored for specific applications and space constraints. Special types without failsafe devices are available upon request.

Specifications and Dimensions
The document details specifications and dimensions for Spicer U-joints and coupling systems, including housing, flywheel, and cardan flange dimensions, with specific partition and thread details.

Intermediate Coupling Systems
The CenTaX-V intermediate coupling is noted for tuning torsional vibrations. Reaction forces from the cardan shaft can affect the crankshaft, especially at angles over 3 to 4 degrees. Flange-mounted bearing housing is recommended to mitigate these forces.

Flanged Bearing Housing Advantages

Protects the crankshaft from reaction forces.
Optimizes torsional vibration tuning with flexible couplings.
Features high-capacity bearings with long-term lubrication for minimal maintenance.
Compact and lightweight design due to hardened aluminum construction.
Extensive internal ventilation to reduce ambient temperature around the flexible coupling.

Technical Data
The document provides technical data for various coupling systems, specifying dynamic torsional stiffness, weight, and dimensions, along with order codes for different configurations.

Product Range
CENTA offers a comprehensive range of advanced flexible couplings and shafts for marine and industrial applications, including types like CENTAMAX-S, CENTAFLEX-DS, and CENTAX-V, each with specific torque capacities.

Company Overview
CENTA is a leading producer of flexible couplings with a global presence, having installed over 15 million couplings since 1970. The company operates worldwide with subsidiaries and agencies in numerous countries, providing extensive after-sales service.

Universal joint shafts are frequently used to transmit the power from a Diesel engine to the driven unit where the driven unit cannot be flange mounted to the engine. Zur Leistungsübertragung von Dieselmotoren zu den angetriebenen Aggregaten werden häufig Kardanwellen eingesetzt. Every Diesel engine produces torsional vibration and every universal joint shaft has a certain torsional elasticity. When these two components are connected to a driven machine a system is created which in many cases will generate very high vibratory torques somewhere within the equipment. In other words there will be...

This axial preload has several advantages: Diese Druckvorspannung hat mehrere Vorteile: • The adhesion of the rubber to the metal is enhanced. • Die Haftung des Gummis zum Metall wird unterstützt. • The damping capacity of the rubber is increased. • Die Dämpfung des Gummis wird erhöht. • When subjected to the high torsional vibration, with the drive side twisting relatively to the driven side, a relative movement occurs simultaneously on the axial plain bearing thus providing considerable friction damping. • Bei Drehschwingungen, d.h. bei relativer Verdrehung von Antriebsseite der Kupplung zur...
