Helical-Hypoid Gear Units

SKM series helical-hypoid gear units is a new-generation of product developed by our company,with a compromise of advanced technology both at home and abroad,its main features are as follows:
1.Driven by hypois gear,has big ratios.
2.Large in output torque,high efficiency,energy saving and environmental protection.
3.Made of high-quqlity aluminum alloy,light in weight and nonrusting.
4.Smooth in running and low in noise,can work long time in dreadful conditions.
5.Good-looking in appearance,durable in service life and small in volume.
6.Suitable for all round installation,wide application and easy of use.
7.The mounting dimension of SKM series are compatible with NMRV series worm gear unit(A part of NMRV050 dimensions are different from SKM28).
8.Modulaw and multistructure can meet the demands of various conditions.

Main Materials

1. Housing:die-cast aluminum alloy (frame size:28 to 58);
2. Gear wheel:20CrMnTi,carbonize & quencher heat treatment make the hardness of gear’s surface up to 56-62 HRC,retain carburization layer’s thickness 0.3 and 0.5mm after precise grinding.

Surface Painting

Aluminum alloy housing：
1.Shot blasting and special antiseptic treatment on the aluminum alloy surface.
2.After phosphating,spray the paint PAL5010 in blue or in grey.
