Automotive Plastic Helical Gear High Precision And High Strength Characteristics

Jul 14, 2017

Automotive Plastic Helical Gear are moving towards larger sizes, more complex geometries, and higher strength, while high performance resins and long fiberglass filled composites play an important role in promoting.

Automotive Plastic Helical Gear have undergone a change from new materials to important industrial materials over the past 50 years. Today they have penetrated into many different applications, such as cars, watches, sewing machines, structural control facilities and missiles, which play the role of transmission torque and movement. In addition to the existing application areas, the new, more difficult to work gear applications will continue to appear, this trend is still in-depth development.

The automotive industry has become one of the fastest growing areas of plastic gear, and this successful change is encouraging. Car manufacturers are trying to find a variety of automotive-driven auxiliary systems, they need a motor and gear, but not power, hydraulic or cable. This change allows Automotive Plastic Helical Gear to be used in many applications, from lift doors, seats, tracking headlights to brake actuators, electric throttle sections, turbine mediators, and more.

The application of plastic power gear is further widened. In some large-scale applications, Automotive Plastic Helical Gear are often used to replace metal gears, such as the use of plastic washing machine transmission equipment, which changes the gear in the application of the limits of size. Automotive Plastic Helical Gear are also used in many other areas, such as ventilation and air conditioning systems (HVAC) damping drives, valve actuators in mobile facilities, automatic sweeper in common lounges, and controllable surface-powered dynamic helix for small aircraft Equipment, military field in the field of the mound and control devices.

Due to the advantages of plastic gear molding and the ability to shape larger, high precision and high strength characteristics, which is the development of plastic gear is an important reason. Early plastic gear development trend is generally less than 1 inch span, the transmission capacity of not more than 0.25 horsepower spur gear. Now the gear can be made into many different structures, transmission power is generally 2 horsepower, diameter range of 4-6 inches. It is predicted that by 2010, the plastic gear forming diameter can reach 18 inches, the transmission capacity can be increased to 10 horsepower or more.

How to design a gear configuration, in the transmission power to maximize the same time to send errors and minimize noise, but also faced with many problems. This poses a high degree of precision machining requirements for concentricity, tooth profile and other characteristics of the gears. Some helical gears may require complex molding operations to produce the final product, and the other gears need to use the core teeth in the thicker part to reduce shrinkage. While many molding experts use the latest polymer materials, equipment and processing technology to achieve the ability to produce a new generation of Automotive Plastic Helical Gear, but for all processors, will face a real challenge is how to cooperate with the manufacture of the entire high-precision product.

Precision gear manufacturers also need to use professional testing equipment, such as the use of double-toothed side of the gear quality control of the rolling detector to assess the gear tooth surface and other features of the computer control detector. But having the right device is just the beginning. Molds who are trying to enter the precision gear industry must also adjust their molding environment to ensure that they produce gears that are as consistent as possible during each injection molding. Since the production of precision gears, the behavior of craftsmen is often the decisive factor, so they must focus on the training of employees and the operation of the control process.

Since the size of the gears is susceptible to seasonal temperature changes, even opening the door allows the temperature fluctuations caused by a forklift to affect the dimensional accuracy of the gears, so the molding manufacturer needs to strictly control the environmental conditions of the molding area. Other factors to consider include a stable power supply, a suitable drying device that controls the temperature and humidity of the polymer, and a cooling unit with a constant air flow. In some cases, the use of automated technology, through a repeated action, the gear from the molding position removed and placed in the transmission unit, to achieve the same cooling.
