When there is a huge Plastic Gear Rack temperature fluctuation in the application environment, when the diameter is large or when generally there is load on its keyway, metal hub manufactured from S45C or stainless steel may sometimes be utilized. In these cases, one’s teeth part and the hub part are attached together with screws. If it is not possible to screw together, two parts are fused with each other and made into fused gears. Ever-Power’s fused gears were created so that the holding power of the fused surface area is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, silent, injection molding enabling low cost and huge production, and able to operate without lubrication by mating with metal gears. However, low strength, inclination to hold heat, large dimensional modify including backlash in comparison to metal, etc. are some of the factors requiring caution. The degree of dimensional changes that take place with plastic gears depend on the ability to resist temperature modify, moisture absorption rate and resistance to chemical substances.
As far as the applications of plastic material gears, they are found in varying industries such as food production machines, gadgets, chemical substance, toy, and medical apparatus industries.
Our engineering department might help in customizing gears to your drawings and specifications.
