GEARBOX EFFICIENCY The operating efficiency of worm-gear reducers ranges from 50% to as high as 95%. A number of factors influence efficiency, including ratio, input speed, tooth geometry, and lubrication. By far, the most important of these is ratio. A lower-ratio unit (5:1 for example) has more threads on the worm and a higher helix angle compared to a high-ratio unit. Higher helix angles mean less sliding friction and hence, higher efficiency. By comparison, helical gears typically have a 98% efficiency per gear mesh. For example, a double-reduction helical reducer has an efficiency approximately 0.98 3 0.98 = 96%. condition of self locking worm gear It China worm gearbox nz has established stable cooperation with many well known universities and institutes in china such as, ZHangZhoug University, HangZhou University, Technical committee of national chain drive standard, Institute of national chain drive, ZHangZhoug application engineering material institute, Huhan material protection institute; and it cooperated to found China First Car chain institute with National chain drive institute.
