When right now there is a huge temperature fluctuation in the application form environment, when the diameter is large or when there is load upon its keyway, metallic hub manufactured from S45C or stainless may sometimes be used. In these cases, one’s teeth part and the hub portion are attached as well as screws. If it’s not possible to screw together, 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 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 able to operate without lubrication by mating with metal gears. However, 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 degree of dimensional changes that happen with plastic gears depend on the capability to resist temperature 
alter, moisture absorption rate and resistance to chemicals.
As 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 equipment industries.
Our engineering department can help in customizing gears to your drawings and specifications.
