When generally there is a large temperature fluctuation in the application form environment, when the diameter is huge or when presently there is load on its keyway, metallic hub manufactured from S45C or stainless steel may sometimes be used. In these cases, the teeth part and the hub portion are attached together with screws. If it is not possible to screw with each other, two parts are fused with each other and converted to fused gears. Ever-Power’s fused gears are designed so that the holding power of the fused surface area is stronger than the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, noiseless, injection molding enabling low priced and large production, and in a position to operate without lubrication by mating with metal gears. However, low strength, inclination to carry heat, large dimensional change including backlash compared to metallic, etc. are a number of the points requiring caution. The degree of dimensional changes that happen with plastic gears depend on the ability to resist temperature alter, moisture absorption price and resistance to chemicals.
As far as the applications of plastic-type gears, they are found in varying industries such as food production machines, gadgets, chemical substance, toy, and medical equipment industries.
Our engineering department can help in customizing gears to your drawings and specifications.
