Antivibration System Manufacturers

Rokang Technology -- your partner in the research, development and production of drive system components and solutions. The Antivibration System( Flexbile drive shaft Assembly) produced by Rokang with torque ratings of 60-30000 N.m which applicable to marine applications, especially for yachts.

Rokang different models designed to match boats powered from 5hp to 1500 hp,we have a system that's right for nearly any boat. 

Future:

  • More silent than any comparable gearbox to prop shaft coupling.
  • Smoother engagement of gearbox.
  • Absorption of driveline vibrations by the Vulkan Megiflex coupling.
  • Preventing high frequency vibrations from causing wear or damage to the prop shaft installation.
  • Allows for even softer flexible engine mounts.
  • Length compensation by the CV drive shaft, so no thrust loads on the Megiflex coupling.
  • Ease of installation; the unit comes in three main components: thrust block, CV drive shaft and fully assembled Vulkan Megiflex unit with premounted gearbox adaptor flange.
  • Saving installation time; because the system contains a drive shaft with two CV joints (unlike other systems), it ‘hinges’ on these two CV joints, which makes installing the unit a piece of cake!
  • All installation materials like bolts, nuts, washers and gearbox adaptor flange included.
  • No maintenance required.
  • Greater torque, smaller size.

 Outstanding technology to improve boats worldwide

Whether you are a professional marine engine installer or an enlighteded boat owner,we can help you find the system that's right for your boat.

Understanding Antivibration Systems in Modern Mechanical and Marine Applications

An Antivibration System is a critical mechanical solution designed to reduce torsional vibration, noise, and misalignment stress within power transmission systems. In applications such as marine propulsion, heavy machinery, and industrial equipment, uncontrolled vibration can lead to premature wear, component failure, and reduced operational comfort. A well-designed antivibration system improves system stability while extending service life.

Core Working Principles of an Antivibration System

Antivibration systems function by isolating, absorbing, and compensating for dynamic forces generated during power transmission. These systems typically integrate flexible couplings, constant velocity (CV) drive shafts, and thrust-bearing structures to ensure smooth torque transfer even under fluctuating loads and alignment deviations.

  • Absorption of torsional and high-frequency vibrations before they reach downstream components
  • Compensation for axial, radial, and angular misalignment between gearbox and driven equipment
  • Protection of bearings, shafts, and gearboxes from shock loads

Key Components and Structural Design

A practical antivibration system is composed of multiple functional elements working together. Each component plays a specific role in maintaining driveline integrity and operational smoothness.

Component Function
Flexible Coupling Dampens vibration and accommodates minor misalignment
CV Drive Shaft Ensures constant torque transmission under varying angles
Thrust Block Absorbs axial forces and protects gearbox bearings

Industrial and Marine Application Scenarios

Antivibration systems are widely applied in environments where high torque, variable load, and continuous operation are required. In marine propulsion systems, they significantly improve onboard comfort and drivetrain reliability. In industrial sectors, they ensure stable performance under heavy-duty conditions.

  • Yacht and commercial vessel propulsion systems
  • Metallurgical and rolling machinery
  • Mining, lifting, and heavy engineering equipment
