Plastic gears are moving towards larger sizes, more complex geometries, and higher strength, while high-performance resins and long glass fiber filled composites play an important role in promoting them. Plastic gears have undergone a course of change in the past 50 years, from new materials to important industrial materials. Today they have penetrated into many different applications, such as automobiles, watches, sewing machines, structural control facilities and missiles, which act as transmission of torque and motion forms.In addition to existing application areas, new and more difficult gear applications will continue to emerge, a trend that is still in deep development.
The automotive industry has become one of the fastest growing areas of plastic gears, and this successful change is encouraging. Automobile manufacturers are trying to find a variety of car-driven auxiliary systems that require motors and gears, not power, hydraulics or cables.This change makes plastic gears deeply used in many applications, from lifting doors, seats, tracking headlights to brake actuators, electric throttle segments, turbine mediation devices, and so on.
The application of plastic power gears is further broadened. In some applications where large sizes are required, plastic gears are often used as an alternative to metal gears, such as plastic washing machine drives, which change the limits of the size of gears used. Plastic gears are also used in many other areas, such as vibration damping drives for ventilation and air conditioning systems (HVAC), valve transmissions in mobile facilities, automatic sweeps in common lounges, power spirals for surface stability control on small aircraft, snail mound in military fields, and manipulation devices.
