When there is a huge temperature fluctuation in the application form environment, when the diameter is large or when generally there is load on its keyway, metal hub made of S45C or stainless steel may sometimes be used. In these cases, the teeth portion and the hub part are attached together with screws. If it’s extremely hard to screw with each other, 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 area is stronger compared to the tooth strength.
The positive characteristics of plastic gears include being lightweight, non-rusting, silent, injection molding enabling low cost and huge 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 a number of the points requiring caution. The degree of dimensional adjustments that occur with plastic gears depend on the ability to resist temperature change, moisture absorption rate and resistance to chemicals.
So far as the applications of plastic gears, they are found in varying industries such as for example food production Plastic Gear Rack machines, consumer electronics, chemical, toy, and medical products industries.
Our engineering department can help in customizing gears to your drawings and specifications.
