Custom Machined Pom Plastic Sprocket Gear Wheel As Your Drawing

plastic pinion gear

When designing a plastic pinion, engineers consider several parameters that affect its performance. These factors include torque, rotational speed, shock loads, clearance requirements, and inertia. They also considered the possibility of the material being exposed to chemicals. However, plastic pinions are not inherently superior to metal pinions in these respects.Plastic pinions can have many advantages. Its lightweight materials reduce drivetrain friction and improve acceleration. The basic equations for gear design can be used for metal and plastic gears. Plastic gears are susceptible to thermal expansion and moisture absorption like other gears. A good design must consider this and provide more significant backlash than metal gears.Plastic gears also have excellent load-carrying capacity due to tooth bending and load-sharing characteristics. This feature allows smaller gear faces to be used without sacrificing their load-carrying capacity. While the surfaces of steel gears can be grooved by load, the surfaces of plastic gears can touch over the entire width. Modulus and pressure angle also affect load carrying capacity. The higher the modulus and pressure angle, the more muscular the root strength. Higher contact ratios reduce root strength, but lower contact ratios increase load-bearing capacity.Since plastic gears undergo thermal expansion and contraction, they are also more prone to warping under strain. This is especially problematic in humid and high-temperature environments. However, the benefits of plastic gear far outweigh any disadvantages.
