Deck/Well Installation Rudder Propeller/Tunnel Thruster/Bow

thruster 

The rudder propeller is one series of our products. It has been approved by CCS, BV, RINA and widely installed, used and served for all types and size of ships. 

The propeller can be freely steered through 360 degrees around the stem. Rudder and Thruster is in one as a combined propulsion and steering unit, so that the full thruster is available in any direction for the ship.

If the prime engine is electric or hydraulic motor, the upper gearbox can be eliminated. The electric or hydraulic motor can be vertically mounted on the fixed flange and the power will be transmitted through a bevel gear in lower gearbox on to the propeller(L-drive).

The power of the diesel engine is transmitted to the Rudder Propeller through an elastic coupling, a clutch and the universal shafts. The rudder propeller transmits the engine power to the propeller via upper and lower bevel gear sets (Z-drive).
 
The rudder propeller can be operated by mechanical, hydraulic or electric-hydraulic unit, which are usually used in tugs, ferry boats and barges etc.
 
There are three installation types: Transom installation, Well installation, Deck installation.

1. The well installation is especially for tugs, ferries, well station, floating dock and survey ships.
The stem length varies with the requirement of the application.
The top mounting plate of the well should, if at all possible, be above the waterline so that the Rudder Propeller can be installed and removed when the ship is floating.

Well installation varies with the distance between the Rudder Propeller and the diesel engine. When the engine room is very small, the Rudder Propeller can be near to the diesel engine and suitable for application in long-range transmission between diesel engine and rudder propeller.

2. The deck installation is a complete propulsion package. It is a reliable and compact propulsion plant.
The chassis carries the totally enclosed propulsion system.
The power of the diesel engine is transmitted to the rudder propeller through an elastic coupling, a hydaulic cluth and a universal shaft. The chassis daily fuel tank and so on.
Installation is fast and simple because they are essentially self-con-rained.
The deck installation unit merely has to be mounted and bolted onto a foundation of deck. Rudder propeller is mounted at the rear chassis.

3. Transom installation is used for ships and vessels whose space of engine room are smaller, such as floating cranes, mounting plate with sealing is fixed on the plate, which means the upper of the Rudder propeller is fixed on the pinaxis, and the lower is clamped on the puching ring.
When rleasing the thruster bearing, the propeller can easily be elevated backwards.
