propellervõlli
Propellervõll, or propeller shaft, is a mechanical component that transmits rotational power from an engine or motor to a propeller, producing thrust. It is a central element of propulsion in many ships and, in systems with mechanical drive, in aircraft and other propeller-driven machines.
In marine propulsion, the propellervõll runs from the main engine, through the hull, to the propeller located
Materials and construction typically use high-strength alloy steels, sometimes stainless steel, chosen for fatigue resistance and
Maintenance emphasizes bearing and seal condition, lubrication, alignment, and shaft balance. Common failure modes include wear
