6. FAQs

6.1 What are the different types of plastic gears?

The different types of plastic gears include spur gears, helical gears, bevel gears, and worm gears. Each type has unique tooth profiles and is suitable for specific applications.

Plastic gears are toothed wheels made of engineering plastics that work with other gears to transmit power or motion. They have some advantages over metal gears, such as being lightweight, rust-proof, low-cost, and able to operate without lubrication. However, they also have some drawbacks, such as lower strength, higher thermal expansion, and lower stiffness.

There are many types of plastic gears, depending on the shape, arrangement, and material of the teeth and the hub. Some common types are:

  • Parallel axis gears: These gears have two axes that are parallel to each other. They can be spur, helical, or internal gears. They can produce high torque and power when used with helical gears.
  • Non-parallel axis gears: These gears have two axes that are not parallel to each other. They can be bevel, spiral bevel, or hypoid gears. They can change the direction of rotation and the speed ratio.
  • Plastic gears with metal hubs: These gears have plastic teeth and metal hubs that are fused or fixed together. The metal hubs provide more strength and stability for the plastic teeth. The hubs can be made of steel or stainless steel.
  • Plastic gears with different materials: These gears use different engineering plastics for different applications. Some common materials are polyacetal (POM), MC nylon, polyurethane, polycarbonate, and polyphenylene sulfide. Some materials can be reinforced with glass fiber to improve their properties.

6.2 What plastic is best for gears?

The choice of plastic for gears depends on the specific requirements of the application. Some commonly used plastics for gears are nylon, acetal, polycarbonate, and polyethylene. Each material offers unique properties such as wear resistance, low friction, strength, and chemical resistance, which makes them suitable for different gear applications.

The choice of the best plastic for gears depends on the specific application and the requirements of the gear system. Several plastic materials are commonly used for gears due to their unique properties, each offering advantages and limitations.
