When presently there is a big temperature fluctuation in the application form environment, when the diameter is large or when there is load on its keyway, metallic hub made of S45C or stainless steel may sometimes be used. In these cases, one’s teeth portion and the hub portion are attached together with screws. If it is extremely hard to screw jointly, two parts are fused jointly 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, calm, injection molding enabling low priced and huge production, and in a position to operate without lubrication by mating with metal gears. However, low strength, inclination to hold heat, large dimensional modify including backlash compared to metal, etc. are a number of the factors requiring caution. The degree of dimensional adjustments that take place with plastic gears depend on the ability to resist temperature alter, moisture absorption price and resistance to chemical substances.
As far as the applications of plastic-type material gears, they are used in varying industries such as food production machines, gadgets, chemical substance, toy, and medical apparatus industries.
Our engineering department might help in customizing gears to your drawings and specifications.
