worm gearbox: A wide ratio and outpput torque

worm gearbox 

C type niman worm has the distinguished features, compared with the teeth type of the common worm wheel, which is meshed together by the concave teeth surface of the cyclinder worm and worm wheel. The outline of the worm is the concave arc rather than the involute or gibbosity arc, the load of the style of the design is little at the unit area due to the fact that the meet of the concave and the gibbosity surface help form the oil theca between the teeth, this design is similar to the meet of the shaft and the sliding bearing, which is obviously improve the conditions of the meet. the conditions which several contact lines is almost perpendicular to the direction of sliding while the concave teeth mesh drive to form the lubrication press and the oil theca between the teeth. The lubrication press is best when the direction of the sliding is perpendicular to the contact lines. Therefore this type has the well application in the industries, such as the transportation,metallurgy,steel,cut,timber,metal process machine and so on.
