Marine Shaft Tail Parts
 

The marine shaft tails manufactured by our company primarily encompass the following components:

Rubber Bronze Bearing

Bronze Bearing
Bronze bearings can be divided into tin 0bronze, aluminum bronze and lead bronze according to the elements. It has the characteristics of low melting point, high hardness, strong plasticity, wear resistance, corrosion resistance and bright color.

 

Propeller Shaft
The transmission shaft is a rotating body with high speed and little support, so its dynamic balance is very important. Generally, the transmission shaft should be tested for dynamic balance before leaving the factory and adjusted on the balancing machine.

 

High Efficiency Kort Nozzle
The shape of the fairing is similar to that of a pear, also known as the Costa propulsion pear shape, and its size needs to be matched with the propeller hub. The fairing can improve the water flow behind the propeller, thus improving the propulsion efficiency.

Propeller Nut
Propeller nuts are an integral component of a ship's propulsion system. They are used to secure the propeller blades to the propeller shaft and ensure that the propeller functions correctly.

 

Kaplan Propeller Duct
A Kaplan propeller duct also commonly known as a Kaplan propeller nozzle, is an integral component of marine propulsion systems, designed to enhance the performance and efficiency of propellers.

 

Propeller Kort Nozzle
A propeller kort nozzle, also known as the Kort nozzle or duct, is a hydrodynamic device that surrounds and shrouds a propeller blade, enhancing its efficiency and thrust.

Benefits of Marine Shaft Tail

 

Propeller Shaft

Propeller shaft have many advantages, including:

 

Low or No Power Losses: Propeller shafts facilitate efficient power transmission, resulting in minimal or negligible power losses during the process, optimising overall performance.

 

Lightweight Tubular Structure: The tubular design of the propeller shaft contributes to its reduced weight, positively impacting the vehicle's overall weight distribution and fuel efficiency.

 

Simple Construction: The propeller shaft's design is relatively straightforward, making it easier to manufacture and maintain, ensuring cost-effectiveness.

 

Safe Power Transmission: With its sturdy construction and reliable materials, the propeller shaft ensures secure and safe power transfer from the engine to the wheels, enhancing driving stability.

 

Low Noise at High Torques: The well-engineered propeller shaft minimises noise generation, even under high torque conditions, providing a smoother and quieter driving experience.

 

Durability: Built from robust materials like high-quality steel, the propeller shaft exhibits exceptional durability and resilience, withstanding challenging operating conditions.

 

Minimal Maintenance: Due to its sturdy construction and efficient power transmission, the propeller shaft generally requires minimal maintenance, reducing downtime and associated costs.

Bronze Bearing

Bronze bearing have many advantages, including:

 

High strength and load capacity
Bronze exhibits excellent mechanical properties, providing high strength and load-carrying capacity. This makes bronze bearing suitable for heavy-duty applications, capable of withstanding substantial radial and axial loads.

 

Wear resistance
Bronze is known for its exceptional wear resistance, which helps reduce friction and minimize wear between moving parts. This property ensures that bronze bearing have a longer service life and require less frequent replacements, reducing downtime and maintenance costs.

 

Low coefficient of friction
Bronze bearing a low coefficient of friction, resulting in minimal resistance between the bushing and the mating part. This translates to improved energy efficiency and reduced power consumption, particularly in rotating or reciprocating motion applications.

FAQ

 

Q: How is a propeller attached to a tail shaft?

A: The propeller is fitted onto a taper on the tailshaft and a key may be inserted between the two: alternatively a keyless arrangement may be used.

Q: Do bronze bearings need lubrication?

A: Bronze bearings need some sort of lubricant to reduce friction in virtually every application. While oil is sometimes used, most applications call for grease.

Q: How tight does a prop nut have to be?

A: Tighten it up as hard as you comfortably can by hand with a standard wrench. Then, screw on the full-size nut and tighten that down independently—again, as hard as you comfortably can, by hand with a standard-size wrench.” That's it.

Q: What is the function of the propeller nut?

A: Traditionally, ship propellers are mounted on a tapered shaft end with a nut and key. The torque is transmitted through friction of the mating surfaces and the key performs a stand-by function if the friction is insufficient.

Q: Requirement of a Propeller shaft

A: High Torsional Strength: The propeller shaft must possess high torsional strength to withstand and endure demanding torque conditions without structural failure, ensuring a smooth power transmission.

Q: What angle should a prop shaft be?

A: Shaft angle affects the maximum propeller diameter. The steeper the shaft angle the further it projects below the hull. A shaft angle of zero – parallel to the waterline – is the most efficient since thrust is straight aft and water flows to the propeller from straight ahead.
