What is shafting system?

What is shafting system?

Shafting consist of propeller shaft,tail shaft and intermediate shafts. Propellers are normally build of bronze and shafting of forged steel. SHIP CONVENTIONAL PROPULSION SYSTEM. Conventional propulsion system can be categorized in following components.

What is shafting and propeller?

Last Updated on Tue, 10 May 2022. The transmission system on a ship transmits power from the engine to the propeller. It is made up of shafts, bearings, and finally the propeller itself. The thrust from the propeller is transferred to the ship through the transmission system.

What is marine shafting?

The shafting system directs the power generated by the engine to the propeller which then provides thrust for the vessel. Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water.

What is the importance of a Sterntube in a ship?

The main function of stern tube bearings is to allow an unrestricted and smooth rotation of the propeller shaft. Apart from stern bearings, the stern tube also houses water and oil sealing glands known as the stern glands. The stern tube is a sensitive part of the ship where the sea water can easily seep inside.

What are the main components of shafting?

Shafts (Machine Components)

  • Turbine.
  • Pistons.
  • Rotors.
  • Impedance.
  • Transfer Functions.
  • Electric Potential.
  • Gearbox.

What are the three types of shafting?

Types of Shafts

  • Transmission Shaft. These shafts are stepped shafts which are used for transmitting power between one source to the other machine absorbing power.
  • Axle Shaft.
  • Spindle Shaft.
  • Machine Shaft.

What equipment can be used to establish the center line of the shafting system?

Optical (or laser) equipment can be used to establish the centre line of the shafting system, to give a reference for cutting through bulkheads and machining of the aperture in the stern frame.

What is thrust block in ships?

A thrust block, also known as a thrust box, is a specialised form of thrust bearing used in ships, to resist the thrust of the propeller shaft and transmit it to the hull.

What is a Sterntube?

The stern tube is a hollow tube which accommodates the bearings, the seal boxes and the propeller shaft. The stern tube is filled with oil, grease or water and forms a barrier between the water outside and the engine room inside the vessel.

What are types of shafts?

They are mainly classified into two types.

  • Transmission shafts are used to transmit power between the source and the machine absorbing power; e.g. counter shafts and line shafts.
  • Machine shafts are the integral part of the machine itself; e.g. crankshaft.
  • Axle shaft.
  • Spindle shaft.
