Plastic gears can be applied with the gear unit, developed a new generation of gear reducer - plastic gear reducer, available plastic gear reducer is certainly sensational, plastic gear when engaging noise is much lower than metal gears, application of plastic gears further broaden the applications of some large size requirements, plastic gears are often used to replace metal gear. Like the re-use of plastic washing machine gear transmission, which changes gear in the application size limits.
One important reason is the plastic gear to develop the advantages of plastic gears can be shaped and molded on a larger, high precision and high strength characteristics. How to design a gear configuration, while maximizing power transfer so that transmission errors and minimize noise, it is also facing many difficulties, which is concentric toothed gear and other features of a very high precision machining requirements.
Due to the size of the gear susceptible to seasonal temperature conversion, and even open the door to let a truck through temperature fluctuations can affect the dimensional accuracy of gears, so molders need for strict control of environmental conditions into weeks, while also considering affect the stability of the power supply and other factors.
Processing of high precision components compared with the general requirements of the molding process, the need for more attention to the details and reach measurement technology to accurately measure the required level. The most common plastic gear teeth are straight, cylindrical and helical gears turbine, almost all made of metal, plastic gears can be manufactured, the gear used to split the mold cavity shape. Since the injection must be allowed when the helical gear machining gear or ring gear teeth are formed is rotated, it requires attention to the details. |
