Where to Buy Polymer Gears
If you're looking to buy polymer gears, you may wonder where to buy them. While you can certainly find them in various stores, you'll want to know where to buy them safely and securely. Here are some tips to keep in mind. First, understand your application. Do you need a micron-sized or nanometer-sized gear? If so, you'll want to make sure you get the right size and ring. Here is a great post to read to know about where to buy polymer gears.
If you're looking for a durable gear, a high-performance polymer material is the way to go. Polymer gears don't break under excessive loads, and they don't need exterior lubrication. And since polymers are moldable, they can be designed to fit virtually any gear. And while metal gears can last much longer, they're usually more expensive and require a great deal of lubrication.
When choosing a material for a plastic gear, you can look at two primary types of materials: Duracon, a polyacetal resin, and MC nylon. You'll probably be most interested in choosing a polymer that has high wear resistance and low water absorption. Those qualities make a polymer gear the ideal choice for applications that need durability, such as an office automation system, a truck loader, or a toy. Generally, polymer gears are made of a plastic material that won't require any type of lubricant, which makes them ideal for environments where cleaning is a must. Plastic gears are also safe to use in high temperatures, but you should keep in mind that the bearing temperature should not be too high.

While plastic gears are a better choice for heavy-duty applications, they are also more complex to design. Few engineers possess the necessary expertise to create plastic gears. So, when choosing a plastic gear, the first step in the design process is to form a team of experts with the necessary knowledge and experience. These experts should include a gear engineer, plastics supplier, manufacturing engineer, and a quality control engineer. Together, they'll develop a design that works in real-life conditions, and create a detailed specification for the prototype.
When choosing a material, remember to consider how elastic modulus and bending strength are affected by temperature and loading. Elastic modulus is directly affected by temperature, but there are materials that offer close to metal-level thermal expansions. Likewise, thermal effects of molding will have a negative impact on long-term dimensional stability of a gear. Plastic parts are susceptible to swelling due to moisture absorption. This reduces the clearance between gear teeth, so designers have to increase the clearances or choose a material with a lower tendency to swell.
Plastic gears have many advantages over metal gears. First, plastic gears are cheaper to produce. They do not require secondary finishing, so they can often save up to 50% or more compared to metal gears. Second, they are flexible and can be moulded to almost any size and shape. Finally, they're quiet, allowing them to be used in a variety of applications. Lastly, plastic gears are less prone to wear than metal gears.
