Ep Gear’s worm gears use correct-angle (90°) non-intersecting shafts to offer an effective remedy for energy transmission purposes demanding higher reduction ratios in confined areas. When effectively used, worm gears offer the smoothest and quietest type of transmission. Given that the effectiveness of a worm travel depends on the direct angle and the number of stars on the worm – because effectiveness is usually the objective, this ratio must be retained as low as possible. To operate correctly, the worm and worm gear employed together need to have the very same diameter, pitch and thread.
