The propeller shaft in a boat engine is fastened to the flywheel by bolts, and it passes through the boat's thrust block and is aligned with the shaft tunnel. It also passes through the stern tube to drive the propeller.
The stern tube shaft itself holds the "prop" shaft in place and shut off the open end when it pierces the aft hull. It is commonly manufactured as cast iron and welded into the frame of the stern of the ship.

What is the function of stern tube system?
The stern tube in marine engineering allows the propellor shaft to penetrate the hull of a ship and prevent the ingress of water. It also acts as a bearing and lubricates that part of the shaft.
How do they make ship driveshafts that run from engine to propeller waterproof when they exit the inside of the ship and enter the water?
at least in small scale, the propeller shaft is run through a tube almost the same size as the shaft but filled with a water proof grease and held in the tube by a cap at the end, (much like a hydraulic piston, it can travel through it but doesn't leak fluid) there are also water tight bearings that the shaft can be ran through. i cant imagine large scale would be much different
Does a hollow metal tube conduct as good as a solid rod of the same material?
as in solid rod there has more free electrons which will cause more current than a hollow metal tube of same dia/length/material.
How does a hydraulic gauge work?
Normally using a calibrated bellows or bourdon tube. As pressure is sensed by the device it inflates the tube or bellow which in turn causes the needle to rotate. Pre-seventies pitot and static systems on aircraft use this very technology to relay information like true air speed to the pilots.
What turbine does not require draft tube?
Draft tube is used to increase the pressure from the low turbine exit pressure to the pressure of the surrounding to which the fluid is rejected.Only reaction turbines require a draft tube as there is low pressure at the exit of the turbine,where as in an impulse turbine the pressure at the inlet and the exit is essentially the same, which is above the pressure to which the fluid is rejected and thus it require no draft tube.
What is the stern tube of a ship?
It is a tunnel-like opening at the vessel's stern, through which the propeller or tail shaft passes, in order to connect the propeller to the engine.
What are the parts of ship's propeller?
1) Trailing edge 2) Face 3) Fillet area 4) Hub or Boss 5) Hub or Boss Cap 6) Leading edge 7) Back 8) Propeller shaft 9) Stern tube bearing 10) Stern tube

What is the types of stern tube of a ship?
Oil lubricated and sea water lubricated stern tube
How can I make a paper tube airplane?
To make a paper tube airplane, you will need a paper tube, paper for wings, a propeller, and glue. Cut the paper tube to the desired length for the body of the airplane. Attach the paper wings to the tube, and add a propeller to the front. Decorate as desired.
What r391 dowty propeller component translates piston and shaft movement to vary propeller blade angle?
The fadec sends a signal to the pcu which in turn ports oil through a beta tube into the cylinder to either the front or backside of the piston to move the blades. The piston is connected to a crosshead assembly inside the propeller hub which slides up and down with the piston to move the blades
What is the use of Thrust Block in the Stern tube of ship?
a big ship
What is the use of thrust block in stern tube of ship?
a big ship
What lead in stern tube oil analysis mean?
Lead in stern tube oil analysis typically indicates wear or degradation of components within the stern tube assembly, particularly the bearings or sealing surfaces. Elevated lead levels may suggest that lead-based materials are being worn down, potentially leading to increased friction and eventual failure if not addressed. Regular monitoring of stern tube oil for lead content helps in assessing the health of the propulsion system and preventing costly repairs or operational disruptions.
Replace tube bearing output shaft 97 jimmy?
To replace the tube bearing output shaft on a 1997 Jimmy, first, ensure the vehicle is securely lifted and supported. Drain the transmission fluid and disconnect the driveshaft from the output shaft. Remove any retaining bolts or clips securing the tube bearing and carefully extract the old shaft. Install the new output shaft, reassemble the components in reverse order, and refill the transmission with the appropriate fluid.
Is levin tube same as blakemore tube?
No. Levin tube is not the same as the Blakemore tube.
