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.


Q1. When can I get the price?

A: We usually quote within 24 hours after receiving your inquiry. If you are urgent, Please call us or let us know in your email so we can prioritize your inquiry.

Q2. How long is the lead time for the mold?

A: It all depends on the size and complexity of the mold. Usually, the delivery time is 25-35 days. If the mold is simple and insignificant, we can do it within 15 days.

Q3. I don't have drawings; how should I start a new project?

A: You can provide us with samples, and we will help complete the drawing design.

Q4. How to ensure product quality before delivery?

A: If you do not come to our factory and there is no third-party inspection, We will be your inspector. We will give you a video with details of the production process, including process reports, product dimensions, structural and surface details, packaging details, etc.

As a plastic gear rack and plastic gear supplier, we always aim to provide the highest quality products and the most comprehensive services and look forward to cooperating with you.
