Plastic gears have gone from curiosity to industrial mainstay in the past 50 years. Today they transfer torque and motion in products as diverse as cars, watches, sewing machines, building controls, and missiles. Even with all the ground they’ve gained, their evolution is far from over as new and more demanding gear applications continue to emerge. Plastic gears are serious alternatives to traditional metal gears in a wide variety of applications. The use of plastic gears has expanded from low-power, precision motion transmission into more demanding power transmission applications. The project aims at the design development analysis of self locking gears as worm and worm wheel manufactured by moulding process to be compared with those manufactured by FDM process to prove suitability of the new gears as replacement to the conventional moulded gears.

Project work will include the design of the gears using Unigraphix NX-8 and analysis of the same using Ansys Workbench 16.0 Testing of the gears will be done to evaluate and confirm the self locking property of gears.
