When right now there is a huge temperature fluctuation in the application environment, when the diameter is large or when there is load upon its keyway, Plastic Gear Rack metallic hub manufactured from S45C or stainless may sometimes be used. In these cases, one’s teeth portion and the hub portion are attached as well as screws. If it is not possible to screw collectively, two parts are fused jointly and made into fused gears. Ever-Power’s fused gears were created so that the holding strength of the fused surface area is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, quiet, injection molding enabling low priced 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 change including backlash compared to metallic, etc. are some of the factors requiring caution. The degree of dimensional adjustments that happen with plastic gears depend 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 for example food production machines, gadgets, chemical substance, toy, and medical gear industries.
Our engineering department might help in customizing gears to your drawings and specifications.
