Advantages of gears made from plastic There are some key advantages of using plastic gears over metal, which include: Plastic is a great weight-saving option Noise reduction Ability to act as a vibration dampener as well as absorb any shock loading that could occur in a gear train Plastic has a lower coefficient of friction Plastic gears will not rust if subjected to or operated in wet environments Minimal lubrication is required due to the physical properties of plastic – some plastics being self-lubricating Disadvantages As with every material, there are also disadvantages of using plastic gears instead of metal ones, some of which are listed here: Plastic is generally weaker than metal, therefore, they are not able to withstand as much load or stresses Dimensional tolerances are not as tight as results able to be achieved with metal Plastic is susceptible to change when subjected to heat or moisture which can result in dimensional shifts and inconsistent fit between gear meshing Injection molding tooling costs are high (if the gears are produced in this way) The cost of raw polymer can fluctuate more than steel making the production cost less stable over a long period of time Limited operation at high and low temperatures Polymers used in their production There are generally two types of polymer used for plastic gear production, Polyamide (Nylon) used for machined gears and Acetal used for molded gears
