- Heat Treatment Processes of SteelOverviewHeat 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
- Industry Insight: Mechanism of Microcrack Propagation Caused by Grinding Burn on Gear Tooth SurfacesGear 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.
- Vibration And Equipment Fault DiagnosisIntroductionIn 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
- Gear Fatigue Strength: Design, Verification, And Engineering ApplicationsIntroductionAs the core component of mechanical transmission systems, the fatigue strength of gears directly determines the reliability and service life of transmission devices. This article systematically elaborates on the key technical system of gear fatigue strength from basic theories, design me
- Gear Load-Carrying Capacity Design, Calculation And Application in Mechanical TransmissionGears serve as the core components of mechanical transmission systems, and their load-carrying capacity is directly pivotal to the reliability and service life of the entire transmission system. This capacity primarily encompasses two critical aspects: tooth surface contact fatigue strength and toot
- Gear Transmission: Design, Verification And ApplicationGears are core components in mechanical transmission systems, and their load-carrying capacity directly determines the reliability and service life of the entire transmission system. The load-carrying capacity of gears mainly involves two critical aspects: tooth surface contact fatigue strength and
- Is Nominal Diameter (DN) The Outer Diameter Or Inner Diameter?In the selection and installation of industrial pipelines, valves, flanges, and other equipment, "Nominal Diameter (DN)" is one of the most frequently used technical terms. However, many new entrants to the industrial field and even some senior technical personnel often fall into a cognitive misunde
- Gear Transmission in Electric Drive Systems - Design And Applications1. IntroductionWith the rapid advancement of new energy vehicles (NEVs), industrial automation, and robotics, electric drive systems are increasingly demanded to deliver high efficiency, high reliability, and lightweight performance. As a core component for power transmission, gear transmission play
- Basic Parameters in Gear Shaper Cutter DesignA gear shaper cutter is essentially a modified gear that cuts the tooth profile of a workpiece gear through backlash-free "meshing" (i.e., generating motion). It can machine various types of cylindrical gears, including external spur and helical gears, internal gears, and double gears with narrow re
- A Comprehensive Analysis of Core Knowledge in Materials Science And Engineering: From Basic Elements To Industrial ApplicationsMaterials are the cornerstone of modern industrial civilization. From chips in electronic devices to core components of aerospace equipment, all rely on the precise control and innovative application of material properties.
