When there is a big temperature fluctuation in the application environment, when the diameter is huge or when generally there is load on its keyway, steel hub manufactured from S45C or stainless may sometimes be used. In these cases, one’s teeth portion and the hub portion are attached together with screws. If it is not possible to screw collectively, two parts are fused jointly and converted to fused gears. Ever-Power’s fused gears are designed in such a way 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 priced and large production, and able to operate without lubrication by mating with metal gears. However, low strength, inclination to carry heat, large dimensional change including backlash compared to metal, etc. are some of the points requiring caution. The amount of dimensional adjustments that take place with plastic gears depend on the capability to resist temperature alter, moisture absorption rate and resistance to chemicals.
As far as the applications of plastic-type material gears, they are used in varying industries such as food production machines, gadgets, chemical, toy, 
and medical gear industries.
Our engineering department might help in customizing gears to your drawings and specifications.
