Anti (Non) Backlash Spur Gear Techniques: Gear Backlash Prevention Method, Scissor Gear

Gear backlash is the clearance between two mating gears. Article describes gear backlash and the gear backlash prevention, and the anti backlash gear design techniques.Design engineers across the industry use different anti backlash gear design techniques, some of them are patented as well. We will discuss the spring loaded scissor gear technique here. I have created a conceptual ProE model for the purpose of explaining the technique. Most of the gear train applications you see around are always contains certain amounts of backlash in it. For some of the application, gear backlash is helpful and thus kept intentionally and for some, it is not desired at all. The gear backlash prevention techniques or the anti backlash gear design techniques
