When right now there is a sizable temperature fluctuation in the application form environment, when the diameter is huge or when presently there is load on its keyway, steel hub manufactured from S45C or stainless steel may sometimes be used. In these cases, one’s teeth portion and the hub part are attached as well as screws. If it’s extremely hard to screw jointly, two parts are fused together and converted to fused gears. Ever-Power’s fused gears were created 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 cost and large production, and in a position to operate without lubrication by mating with metal gears. However, low strength, tendency to hold heat, large dimensional change including backlash compared to metal, etc. are some of the points requiring caution. The amount of dimensional changes that happen with plastic gears rely on the capability to resist temperature change, 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 gear industries.
Our engineering department might help in customizing gears to your drawings and specifications.
