H B系列标准的变速箱&特的变速箱

Special gearbox for steel mills, sugar mills, cement factories, seamless steel pipe factory and so on. Standard gearmotors,Planetary gearbox.The gearbox are reliable drive component for the use in different industry sectors. They have many features as follows:Standard gearbox:A fine-progression series covers a nominal torque range between 2000 and 9000000Nm.The basic gear unit can be optimally adapted to customer requirements by fitting different add-on pieces like motor bell housings, gear unit swing-bases or backstops.Designing noise-absorbing housings by means of the computing program;Achieving exceptionally large contact ratios.The gear units not only have a high efficiency but also a favorable thermal conduction through enlarged housing surface areas;Large fans incorporating a new type of air conduction fan cool are being used.Specialgearbox:Design and manufacture with the requirement of customer.With forced lubrication system.DIN grade 4-6 precision gear ground by CNC profile grinding machine.Hardness HRC58-62.High load capacity and low noise.Use of alloy steel, after quenching and tempering, carburizing heat treatment.
