Products Description

Input pinion shaft is a core component in mechanical transmission system, which can both transmit power and support rotation, because of its high strength, wear resistance, high torque transmission and other characteristics, it is widely used in the transmission system of mining machinery.

What are the aspects of our strict quality control for input pinion shafts?

1. Material control

Raw material testing: chemical composition analysis of raw materials (spectrometer testing) and mechanical properties testing (hardness, tensile strength).
- 2,Heat treatment and surface strengthening of input pinion shaft
  
  Carburizing and quenching process: Control the depth of the carburizing layer (e.g. 0.8~1.2mm) and the surface hardness (HRC 58-62) to avoid overcooking or soft spots. And verify the organization uniformity by microhardness tester and metallographic analysis.
  
  Nitriding/Induction hardening: Surface strengthening of input pinion shaft for special requirements to improve wear resistance.
