What are the advantages of poly gears? Consider cost, accuracy, noise reduction, liquidity, and intensity. Which is the best choice for your machine? There are many advantages to choosing poly gears, but which is best for you? Some examples of poly gears are listed below. To learn more, please read on!

Poly gears have several advantages. For beginners, they can reduce the residual stress caused by hardening or welding gear teeth. This is because the polymer shrinks during the molding process, reducing the total weight of the gear. In addition, if the gears are the right size, they can support the whole working load of the chain. But the price of poly gears is a significant consideration.
Plastic gears are made of engineering plastics, such as polyformaldehyde, MC nylon, peek, and u-PE. They are usually mounted on metal hubs and stainless steel or S45C. Then connect the two parts of the gear with screws. Similar methods are used to assemble multiple gears in toy or office automation applications. The hub of poly gear can be made of various materials, including oil-filled polyamide resin.

Poly gears precision manufacturing helps you meet all your needs. Precision gear manufacturing is our specialty.
Plastic gears can be made of various materials, including nylon, polyester, and acetal copolymers. These materials have specific properties and good fatigue and wear resistance. A wide range of thermoplastic materials enables designers to handle different temperature conditions. For example, polybutylene terephthalate can be used at 212degf. On the other hand, nylon 6/6 has a higher thermal limit than polyphenylene sulfide.
noise reduction
The research on noise reduction of multi-gear shows that when the shaft angle is inclined, the noise produced by helical gear is the lowest. Within this range, the radial speed of the gear changes significantly. Gear runout is also a contributing factor. If the gear jumps too much, the contour contact will be lost, and the driver will jump to the next tooth. You will also hear the impact of teeth leaving the mesh.
The gear's acoustic activity depends on its teeth' geometric direction. The study of polymer spur gear shows that polymer is an effective solution to reduce the noise of the transmission system. In addition, Kumar et al. Studied the vibration fault detection of polymer gears using high-order statistical indicators. In the same study, radinov et al. Studied the acoustic characteristics of polymer pinion shafts and gears and concluded that polymer gears are better than steel gears.
