Involute Tooth Line Motor Shafts Modulus 3 Shaft Heat Treatment 28 Width
The tooth width of motor shaft is 28, and its heat treatment adopts carburizing and quenching process, The heat treatment process of the product is carburizing quenching, carburizing process is a very old process, in recent years, there is a high concentration of carburizing process.
Local carbon poor on the surface after carburizing:
Causes and hazards: solid carburization, charcoal particles are too large or mixed with stones and other impurities, or infiltration agent and charcoal mixed not evenly, or workpiece contact will cause local no carbon or poor carbon. Dirt on the surface of the workpiece can also cause carbon poverty.
Prevention methods:
The solid carburizing agent must be prepared in proportion and stirred evenly.
Pay attention to the workpiece loading furnace should not contact. Solid carburizing to tamp carburizing agent, do not make carburizing collapse and the workpiece contact.
But remove the dirt on the surface.
