When presently there is a big temperature fluctuation in the application environment, when the diameter is large or when generally there is load upon its keyway, metal hub manufactured from S45C or stainless may sometimes be utilized. In these cases, the teeth portion and the hub portion are attached together with screws. If it’s extremely hard to screw jointly, two parts are fused collectively and made into fused gears. Ever-Power’s fused gears are designed so that the holding strength of the fused surface is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, peaceful, 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 carry heat, large dimensional alter including backlash compared to steel, etc. are some of the factors requiring caution. The degree of dimensional adjustments that occur 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-type gears, they are found in varying industries such as for example food production machines, gadgets, chemical, toy, and medical products industries.
Our engineering department might help in customizing gears to your drawings and specifications.
