The ideal transmission option is when large transmission reduction is required. A worm equipment is similar to a helical gear with a throat lower to improve the outer diameter of the wheel. The throat permits the worm equipment to wrap totally close to the threads of the worm. By chopping the threads on the worm relatively than the teeth, and by changing the number of threads, various ratios can be achieved with no shifting the mounting arrangement. A unique feature of worm gears and worm gear assemblies is their potential to avert reverse rotation.
