When right now there is a large temperature fluctuation in the application environment, when the diameter is large or when there is load on its keyway, metal hub manufactured from S45C or stainless steel may sometimes be utilized. In these cases, one’s teeth portion and the hub portion are attached together with screws. If it is not possible to screw with each other, two parts are fused collectively and made into fused gears. Ever-Power’s fused gears are designed 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, tranquil, injection molding enabling low cost and huge production, and able to operate without lubrication 
by mating with metal gears. However, low strength, tendency to hold heat, large dimensional change including backlash compared to metal, etc. are some of the points requiring caution. The amount of dimensional changes that take place with plastic gears rely on the capability to resist temperature alter, Plastic Gear Rack moisture absorption rate and resistance to chemicals.
So far as the applications of plastic-type material gears, they are found in varying industries such as food production machines, consumer electronics, chemical substance, toy, and medical apparatus industries.
Our engineering department might help in customizing gears to your drawings and specifications.
