The gears of the series H right angle gearbox are conical gear with curvedteeth of Gleason tooth. the gears have large load carrying capacity and workingsmoothly, and is not sensitive to installation tolerance and deformation, but its axial thrust is larger and its rotation direction relate to direction of torque.

The gears are made with a steel 20CrMnTi. As the surface of cog-tooth iscarburizing and quenching, the surface of tooth has higher hardness, whereas the core has better toughness.

The horizontal shaft of series H right angle gearbox is direxct connected with a diesel, a horizontal type motor, a turbine, etc. Prime mover and after acceleration(or deceleration) the power is exported by the Vertical shaft. The series H right angle gearboxes are used for deep well pumps, axial pumps, inclined flow pumps, major axis pumps, sub-fluid pumps and other a variety of vertical shaft. working machines to be driven and speed to be changed. They are used in a variety of fields such as: hydraulic engineering, municipal water supply and sewage disposal, smelter, mining area, petroleum and chemistry industry, fire protection and oceaneering, etc.. A variety of type and transmission ratios are available to meet specific requirements of high and low speed prime movers and workingmachines. Large capacity thrust bearings make the structure of working machine to be simplified. The series gearboxes have featuies of wide application range, economy, highly efficient, space-saving, and the ability to function well under varying climatic conditios.
