40Cr, 34CrMo4 ,BS ,NF,JIS Forged Gear Steel Shafts For Railway Transport With ISO

Description:

The gear shaft is the mechanical parts to support turn parts and the turning together

with it to transfer movement and it generally is metal round bar, having different diameter.  According to the axis of the different shape, shaft include crankshaft and direct axis.According toits loading conditions, shaft can be divide into rotors, mandrel and transmission shaft. When rotors isunder bending moment and under twist,when it is working , and is most main mechanical shaft,such as all kinds of gear reducer shaft.Mandrels is used to support turn parts,it is only under bending moment and not  under transfer torque. Somemandrels rotate, such as shaft of railway vehicles, but some mandrels don’t rotate, such as supporting the pulley shaft, etc.Transmission shaft is mainly used to transfer torque and not under bending moment,such as crane mobile mechanism of long axis, the car\'s drive shaft, etc.

Its’ material is the carbon steel or alloy steel,butnodular cast iron or alloy cast iron is also used .The ability generally depends on intensity and rigidity, when high speed, depends on the vibration stability.

Process:Ingoting-->forging-->first heat treatment--> rough machining -->second heat treatment-->finished machining

Applications:

The gear shaft is widely used in mining machinery, shipping machinery, wind power machinery, railway transport,etc.
