The American Gear Manufacturers Association (AGMA) Standard 6034, Practice for Enclosed …Worm gears are an ingenious way to turn motion into power, featuring a spiral-threaded shaft (akin to a screw) that turns and drives the meshing wheel gear. This type of setup is simple yet incredibly effective in turning momentum into usable energy. The screw and wheel meet at a 90-degree angle to form a right angle gearbox. Introduction. A worm gear is used when a large speed reduction ratio is required between crossed axis shafts which do not intersect. A basic helical gear can be used but the power which can be transmitted is low. A worm drive consists of a large diameter worm wheel with a worm screw meshing with teeth on the periphery of the worm wheel. A spring-loaded worm wheel. Another method for eliminating the backlash is to use a spring-loaded split worm. In this case the worm shaft consists of two pieces which are spring loaded and the teeth of the worm shaft is always engaged with the worm wheel. Another method is to create a worm gear pair with a variable tooth pitch. The worm gear and worm wheel have axes at 90° to each other, so power transmission is at 90°, which is different from spur gear. In a single start worm, for a 360° turn of worm gear the wheel moves one turn. Worm gears are mainly used for large gear/speed reductions in the range of 20:1 and even up to 300:1. Worm gears possess a unique ...
