The axial load generated by the impeller shaft during high-speed rotation is transmitted through the structure shown in the figure to the low-speed drive gear. It is borne by the bearing of the main drive shaft. This structure increases the operating stability of the impeller shaft and reduces mechanical losses of the unit.
Bull gear shaft: Alloy steel (AISI 4320)
Main drive shaft: Alloy steel (AISI 4320)
Rotor shaft: Forged steel (AISI 9310H stainless steel)
