description
- The efficiency of a worm gear drive depends on the lead angle and number of starts in the worm. The angle generally decreases with increasing ratio and worm pitch diameter. For increased efficiency the ratio should be kept low.
features
- Increased efficiency with lower ratios
- Resistance to back driving with some ratios
- Minimal space requirements
- High ratio speed reduction
- 90° nonintersecting shaft applications
