After preliminary processing, the workpiece is subjected to quenching and tempering heat treatment to adjust the hardness of the core of the workpiece to meet the design requirements, Rockwell hardness machine used for workpiece hardness testing, Optical Microscope to observe the metallographic microstructure of materials, reuse Victorinox (Micro Vickers) the hardness distribution of the nitride layer on the surface of the workpiece is tested by the micro hardness machine, to ensure the physical properties of the component materials meet the requirements of the reducer design.

Using precision measuring tools such as air gauges, comparison type inner and outer diameter gauges, autonomous dimensional inspection of on-site workpieces to ensure the correctness of the size processing. Use three-dimensional measuring instrument to detect the geometric tolerance of the workpiece. The gear tester grasp machining accuracy and pitch error of the tooth profile to reduce the noise and vibration of the reducer.

Plasma Nitriding is applied to the surface of the gear, which has the advantages of low deformation and high wear resistance. Its surface hardness is as high as about 840Hv, which provides the wear resistance required for gear movement. The hardness of the gear core can be adjusted to 30Rc to obtain a moderate toughness, so that the gear has surface anti-wear and core impact resistance characteristics and increases the gear life. The use of professional tooth profile grinding technology makes the meshing and disengagement between the teeth smoother, reducing the generation of noise and vibration, reducing backlash and improving the service life of the product.
