When generally there is a sizable temperature fluctuation in the application environment, when the diameter is huge or when presently there is load on its keyway, metal hub manufactured from S45C or stainless steel may sometimes be used. In these cases, one’s teeth portion and the hub portion are attached together with screws. If it is extremely hard to screw jointly, two parts are fused with each other and made into fused gears. Ever-Power’s fused gears were created in such a way that the holding power of the fused surface is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, quiet, injection molding enabling low cost and large production, and in a position to operate without lubrication by mating with metal gears. However, low strength, tendency to hold heat, large dimensional modify including backlash compared to metallic, etc. are a number of the factors requiring caution. The amount of dimensional changes that occur with plastic gears rely on the capability to resist temperature alter, moisture absorption rate and resistance to chemical substances.
As far as the applications of plastic-type gears, they are used in varying industries such as food production machines, gadgets, chemical substance, toy, and medical devices industries.
