As a professional China Speed Increasing Gear Box manufacturer and equipped with a famous factory and plant, as well as providing with transmission gearbox for sale, welcome to check the process and layout with Hani New Energy and Technology.
Speed Increasing Gearbox of 90m Finishing Mill/ Wire Rod Mill
Details and Composition :
Speed Increasing Gearbox of 90m Finishing Mill/ Wire Rod Mill used carbon alloy steel forging blank, after roughing, workpiece needs to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing. The fine grind of the tooth surface to ensure the high accuracy, after finishing the production of gear, the balance test is needed, the experienced speed is 1500r/min and the balance level is G2.5.
Speed increasing gearbox is composed of increasing gearbox body assembly, support base, big gear, transmission axis, matching gear shafts and lubrication system etc.
