Aquadrive CVB32.30 – Moduline B30 Anti-Vibration CV Shaft System

The Aquadrive CVB32.30 Moduline B30 is a heavy-duty marine propulsion driveline system designed to isolate the engine from propeller forces and vibration. The system transfers propeller thrust through a dedicated thrust bearing mounted on the vessel foundation, reducing load on the gearbox and improving onboard comfort and drivetrain reliability.

The Aquadrive system combines a constant velocity (CV) shaft, a thrust bearing assembly, and a gearbox adapter flange. The CV shaft contains two universal joints connected by a floating shaft, allowing axial and radial movement while maintaining smooth torque transmission even when the engine moves on its mounts.

The Moduline modular construction allows flexible installation and simplifies engine alignment. The modular system reduces vibration transfer to the hull while ensuring reliable propulsion performance.

Main Components

Constant velocity shaft (CV joint assembly)
Thrust bearing with rubber suspension
Gearbox adapter flange
Shaft sleeve connection

Propeller Shaft Options

B30 standard version supports the following propeller shaft diameters:

40 mm
1 3/4"
45 mm
50 mm
2"
2 1/4"

Notes

Rated application examples are based on optimal conditions with approximately 2° joint angle for each CV joint. If the operating angle exceeds 2°, the maximum permitted power should be reduced by approximately 8–9% for each additional degree.

The maximum allowable joint angle typically ranges between 5° and 8°, depending on propeller shaft speed.
