The new worm reducers have the following outstanding advantages:

• With cubic structure,RV030-105 is made with die cast aluminium material body and RV 110-150 cast iron ma- terial. The product owns advantages of good appearance, small volume, quick radiating, flexible mounting.
• The worm shaft was produced by special heat treatment with superior alloy steel; The meshing of the worm wheel haspatented copper alloy. Their performances are advantageous over other suppliers in China.
• The worm gear and worm shaft adopt precision and meshing to ensure the stable transmission、low temperature、low noise level、high efficiency and long service life.
• The input and output parts are treated by smooth,and dusty proof to increase the quality and its service life. 
• High quality bearing and seals to prevent from oil leakage.
• JWB+NMRVseries is worm gear reducer with variator,which can adjust speed on load,to obtain variable output speed.

RV series is widely used,and an ideal choice for modern industrial equipments to realize big transmission ratio.
