When presently there is a large temperature fluctuation in the application environment, when the diameter is huge or when generally there is load on its keyway, metallic hub manufactured from S45C or stainless may sometimes be used. In these cases, the teeth portion and the hub portion are attached as well as screws. If it’s extremely hard to screw with each other, two parts are fused together and made into fused gears. Ever-Power’s fused gears were created in such a way that the holding strength of the fused surface is stronger than the tooth strength.
The Plastic Gear Rack positive characteristics of 
plastic gears include being lightweight, non-rusting, quiet, injection molding enabling low cost and huge production, and in a position to operate without lubrication by mating with metal gears. On the other hand, low strength, tendency to carry heat, large dimensional change including backlash in comparison to metal, etc. are a number of the points requiring caution. The amount of dimensional changes that occur with plastic gears depend on the capability to resist temperature change, moisture absorption price and resistance to chemicals.
So far as the applications of plastic-type gears, they are found in varying industries such as for example food production machines, consumer electronics, chemical, toy, and medical tools industries.
Our engineering department might help in customizing gears to your drawings and specifications.
