When designing with polymers, look for one that functions differently in the system. Dissimilar polymers have different properties and can create smoother, cooler drives with less wear. Also, matching the same plastic in adjacent gears makes it easier to match dimensional changes that can occur when temperature or moisture changes. This is especially helpful for housing. For more information, read this article. This article will introduce you to polymer gears and their characteristics. This article will cover the main advantages and disadvantages of each. Duracon The company's line of polyxymethylene/acetal resins, including Duracon POM, is based on noise-reduction technology and is used in plastic gears, bearings, automotive components, and audio visual equipment. These products have outstanding noise and vibration-reduction properties, and are used in most types of gear applications. Read on to learn more about this innovative resin. Here are some of the benefits of Duracon. Plastic-made gears exhibit lower wear and friction than metal-made gears. Their shape changes from the mold to the final product.Tooth wear is also significantly reduced. This is a problem when gear teeth are too thin on the top of the gear and too thick on the bottom. The result is a gear that is too thin on top and too thick on the base. This causes excessive pressure angles, which can lead to binding and wear. MC nylon MC nylon and POM are two common polymers used for plastic gears. MC nylon is stronger than POM, with 1.2 times the tensile strength. Both materials can be used for bearing assembly. POM is typically used for smaller gear lots, while MC nylon is best for large gear lots. POM is more durable than MC nylon, and POM is better suited for applications where contact with water or high humidity will occur. The temperature increases during meshing and ejection from the die for both materials. The results are similar for MC nylon and metal gear pairs. The difference is in the temperature at which the teeth mesh. Both polymers exhibit good thermal conductivity, which means that they are likely to last longer in a gear set. However, if you are comparing gears made of different materials, you should be careful not to choose plastic over metal. Polyurethane The process of molding polyurethane gears involves multiple steps, each with a different set of operational parameters. The process involves cooling, solidification, ejection from the die, and final trimming. The end result is a gear that is both rigid and flexible. These factors, combined with the flexibility of polyurethane, provide a high degree of reliability. Here are the steps in the process. Let's explore them in more detail. First, you need to know the manufacturing process. Polyurethane gears are made from rubber or metal moulds, and polyurethane elastomer is poured into the mold. Polyurethane gears are vulcanized twice and then heated for 24 hours. During the casting process, most gear sizes are completed; the final product may require a few minor details to be machined. Polyurethane gears have many advantages, including their flexibility, rigidity, and noise-free operation. Liquid crystal polymer Injection molded parts with intricate features can benefit from a material like liquid crystal polymer. This material is relatively non-flammable, chemical and heat-resistant, and it is also extremely dense (1.8 grams per cubic centimeter). DTUL tests indicate that the materials can sustain a load of 275 degrees Celsius without breaking. They also have low linear expansion, making them ideal for use in medical applications. Generally, a designer should start with published data sheets when choosing a material for gears. However, it is important to test potential gear resin formulations for fatigue, wear, and noise before selecting a polymer for a specific application. Data from Celanese's Plastic Gear Evaluation and Research unit will be useful in the development of gear design. Ultimately, however, the gear design should be verified in the field. Polycarbonate The properties of Polycarbonate gears depend on the filler materials they contain and their modulus. Fibers and fillers can dramatically change a gear's performance. Adding short-glass fibers to an acetal copolymer produces gears with double the tensile strength and triple the flexural modulus of the base resin. Adding fibers longer than 10 mm has a dramatic effect on strength and stiffness. In addition to their lightweight properties, plastic gears can be fabricated to meet the requirements of advanced electromechanical and mechanical elements. Additionally, many gears made of plastic can achieve AGMA Q7 quality levels. Molders can also produce Q10-level gears. For gear manufacturers, choosing the right plastic material for the project is critical to the end result. For those who are unsure of how to make a polycarbonate gear, consider the advantages and disadvantages of each material. Polyphenylene sulfide Toray Industries has formulated polyphenylene sulfide (PPS) as a high-temperature thermoplastic polymer that exhibits a variety of desirable properties. These include resistance to abrasion, heat, and mildew. Furthermore, PPS is resistant to aging, sunlight, and dyes. To achieve these desirable properties, polyphenylene sulfide is reacted with a solvent called N-Methyl-2-pyrrolidone.One of the primary criteria of gear materials is wear resistance. Many different composite materials have been studied to assess their wear resistance. In general, composite materials have a lower coefficient of friction than neat plastic. This property is further improved by increasing the fiber content. Carbon fiber composite has an advantage over neat plastic in terms of wear resistance. The material is also highly recyclable and can be used in gear manufacturing. For these reasons, a polymer gear may be an excellent choice for many applications.
