In the field of mechanical transmission, gear transmission is widely used in core equipment such as automobiles, aerospace, and construction machinery due to its advantages of high transmission efficiency, wide power range, and precise transmission ratio. However, gears are subjected to complex alte

OverviewHeat treatment is a critical metalworking technology that modifies the microstructure of steel through precisely controlled heating and cooling cycles. This process is essential for tailoring the mechanical properties of steel—such as hardness, toughness, strength, ductility, and wear resist

Gear grinding is the final "finishing" step in gear manufacturing, determining the tooth surface's form accuracy, roughness, and load-bearing capacity. However, improper control of the grinding process can lead to thermal damage on the tooth surface, commonly known as grinding burn in the industry.

IntroductionIn the industrial sector, machinery such as motors, fans, water pumps, compressors, and steam turbines is indispensable. Almost all these devices "shake" during operation, a phenomenon known as vibration. Vibration is not only a common physical occurrence but also a key window into under
