The Mast Tube Assembly is a tubular steel shaft that is fitted with two bearings to support the main rotor vertically within the transmission. This provides structural integrity and stability to the main rotor system. The mast driving splines on the upper portion of the mast engage with the transmission's upper-stage planetary gear, allowing the mast to rotate the main rotor in a counterclockwise direction (when viewed from above). This transmits the necessary torque from the transmission to the main rotor.Attributes:• Manufactured to precise specifications and are built for durability and reliability• Provides the mounting point for the main rotor and control assembliesApplications:The Mast Tube Assembly incorporates splined or rubber couplings to provide flexibility in the tail rotor drive shaft, which connects the main transmission to the tail rotor gearbox. This helps absorb vibrations and stresses in the drive system. Its proper functioning is vital for the safe and reliable operation of the engine.
