A novel coupling combines the benefits of the popular Centaflex AGM/ACV with the Centalink silent driveshaft to provide a flexible coupling solution that substantially reduces noise and vibration.
Marine power transmission specialist Centa Transmissions has developed a new and innovative coupling that combines the benefits of the existing and popular Centaflex AGM/ACV with the Centalink silent driveshaft to provide a flexible coupling solution that substantially reduces noise and vibration.
The new Centajoint/AGM/ACV coupling eliminates the need for a UJ shaft and replaces this with the link assembly which has more sound attenuation than the UJ, allows flexibility and facilitates a longer shaft reach.
This mounts directly onto the gearbox output flange and provides a flexible coupling solution that helps to eliminate noise and vibration created through engine movement.
The Centajoint shaft consists of a series of highly efficient links that use flexible rubber bushes to isolate the components and provide the required movement, without wearing the metal.
Significantly, it does not require any lubrication, which is a major benefit given that the limited access under the gearbox can often mean that maintenance is overlooked.
This enables this new all-Centa coupling to compensate for axial, radial and angular misalignment, eliminate backlash and provide a cost-efficient and maintenance-free solution for riverboats and marine vessels.
