When right now there is a large temperature fluctuation in the application environment, when the diameter is huge or when there is load on its keyway, steel hub made of S45C or stainless may sometimes be used. In these cases, one’s teeth portion and the hub portion are attached together with screws. If it’s not possible to screw together, two parts are fused with each other and made into 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, peaceful, injection molding enabling low priced and huge production, and able to operate without lubrication by mating with metal gears. However, low strength, inclination to carry heat, large dimensional alter including backlash in comparison to steel, etc. are some of the factors requiring caution. The degree of dimensional changes that take place with plastic gears rely on the ability to resist temperature alter, moisture absorption price and resistance to chemicals.
As far as the applications of plastic-type gears, they are found in varying industries such as food production machines, consumer electronics, chemical, toy, and medical gear industries.
Our engineering department can help in customizing gears to your drawings and specifications.
