Hollow shaft is a type of shaft component with an internal cavity. Its outer surface is usually machined with a stepped cylinder and has external key grooves, and internal key grooves may also be opened in the inner hole.It is widely used in automotive transmission systems, wind power generation, aerospace, machine tool spindles, generators, etc

Application:

automotive transmission systems, wind power generation, aerospace, machine tool spindles, generators, etc

C45 Chemical Specification :

Advantage :

C45, as one of the most widely used carbon structural steels, has three core advantages:
balanced performance,
convenient processing,
and controllable cost.

Product Procedure:

Forging,rough machining,heat treatment,final processing

Steel Grade Choice:

Forged steel drive shaft: high-quality medium carbon steel and medium carbon alloy steel, such as 40, 45, 35Mn2, 40Cr, 45Cr, 35CrMo steel, etc;

This type of material is subjected to quenching and tempering (or normalizing) heat treatment to improve its processing performance. The material should have high strength, certain impact toughness, sufficient bending and torsional fatigue strength and stiffness, and the journal surface should have high hardness and wear resistance. This type of material is medium carbon alloy steel, which is subjected to quenching and tempering (or normalizing) heat treatment to improve its processing performance.
