When right now there is a large temperature fluctuation in the application form 
environment, when the diameter is large or when right now there is load upon its keyway, metallic hub manufactured from S45C or stainless steel may sometimes be used. In these cases, one’s teeth part and the hub part are attached together with screws. If it is extremely hard to screw collectively, two parts are fused with each other and made into fused gears. Ever-Power’s fused gears were created in such a way that the holding power of the fused surface is stronger than the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, peaceful, injection molding enabling low cost and large production, and able to operate without lubrication by mating with metal gears. On the other hand, low strength, tendency to carry heat, large dimensional change including backlash compared to metallic, etc. are some of the points requiring caution. The degree of dimensional adjustments that occur with plastic gears rely on the capability to resist temperature modify, moisture absorption rate and resistance to chemical substances.
As far as the applications of plastic material 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.
