Gear Shaft Heavy Steel Forgings Transmission Gear Precision Gear ASTM A388

1. Quick Detail

  1. Drive gear shaft, transmission gear shaft, steel shaft, shaft forging
  2. Alloy steel, carbon steel or as per customer’s requirements.

2. Description

The gear shaft is mainly subjected to alternating drive, impact drive, shear stress and contact stress. The shaft is easy to crack, and the teeth are easy to wear. Therefore, the core of the gear shaft is required to have a certain strength and toughness, there is a high fatigue limit and the ability to resist multiple shocks. The surface should also have a certain degree of hardness and wear resistance.
The gear shaft, the work not only bear the moment and bear the torque, is the most common machinery in the shaft, such as the shaft of the reducer, etc..
II spindle for supporting rotating parts only to withstand the bending moment and does not transfer torque, some spindle rotation, such as railway vehicle axle, some spindles do not rotate, such as supporting pulley gear shaft.
Third, gear shaft, is mainly used to transmit torque and not subjected to bending, such as crane traveling mechanism of optical axis, automobile drive shaft and so on.

3. Applications

As the one of important part of transmission system of the machinery, the gear shaft, transmission gear shaft widely used for marine &boat industry, Mining machinery industry etc.
