The spiral bevel gearbox speed reducer is a kind of practical product. It adopts all-geared vice transmission by drawing from the structure of SEW gear reducer while still keeping the compatibility of the installation dimension of this speed reducer and NMRV worm gear speed reducer. Thus, the meshing friction is small so that the transmission efficiency can be up to 90% which is 10%-40% higher than the worm gear speed reducer. Meanwhile, it is made of superior alloy of which the surface is hardened. This spiral bevel gearbox speed reducer adopts high precision gear grinding machine for machining. The gear is a kind of hardened face gear of which the strength and service life is greatly higher and longer than that of the worm gear speed reducer.
This series of speed reducer can be widely used for food packaging machinery, chemical equipment, wood working machine, crane, construction machinery, compressor, transport conveyor, dredger, engine and transverter, washing machine, metal rolling machine, draught fan etc.
1. Shell: aluminum alloy (engine base: 050-090); gray cast iron (engine base: 110);
2. Gear: 20CrMnTi, carbonitriding; the hardness of the gear surface is 58-62HRC; the thickness of the carburized layer is maintained as 0.3-0.6mm after refined grinding.
Surface coating (aluminum alloy shell)
1. The surface is treated by shot blasting first and then anti-corrosion treated to keep it metallic silver white. Meanwhile, it is gasoline, xylene and some other organic solvent resistant.
2. It is coated with RAL9006 silver gray or RAL5010 blue coating after bonderizing.

The spiral bevel gearbox speed reducer has the following features:
1.The speed reducer adopts hypoid gear which has large transmission ratio, stable transmission and low noise. It is suitable for long-term working in hostile environment.
2.It has large output torque, high transmission efficiency and it is energy saving and environment friendly.
3.The shell is made of superior alloy steel which is light weighed, rust free, attractive and durable.
4.The spiral bevel gearbox speed reducer has small size so that it can be installed in all dimensions. It has wide application and is convenient to use.
5.This speed reducer adopts modular assemblies, so that it can satisfy different transmission conditions by providing various combinations.
6.The installation dimension of BKM series speed reducer (spiral bevel gearbox speed reducer) and NMRV worm gear speed reducer is totally compatible (some dimensions of BKM050 and NMRV050 are different).
