Double Spur Gear Plastic

Double Spur Gear Plastic Product-2.2A double spur gear plastic is a type of plastic gear that has two spur gears stacked together. Generally, they come in different diameter sizes.

Plastic spur gears have a long history in autos, appliances, office equipment, tools, etc. Designers continue to extend their use in transferring torque and motion as polymers improve and processing gains in sophistication. They often choose plastic for gears over metal because of its many benefits.

Manufacturing Method Of Double Spur Gear Plastic:

Plastic gears are manufactured in the same form as metal gears, the only difference being the material used. Each type of gear is produced to meet the needs of a process or application, which also determines how it will be manufactured. The main difference between making plastic gears and metal gears is that plastic materials do not have the strength of the metal.

Temperature changes strongly affect the strength and stiffness of plastics, which must be considered when designing plastic gears. In addition, plastic gears have lower elastic modulus and mesh stiffness, which causes them to deflect under load.

Regardless of the similarities between metal and plastic gears, plastic gears have other factors that must be considered during their engineering and design phase.

Double Spur Gear Plastic Process:

CNC Machining Of Double Spur Gear Plastic:

CNC machining is a cutting process that can produce any type of gear. The CNC process removes layers of plastic material from plastic discs or rods. Several tools are used in this process, which is programmed with G code to guide the movement of the tools. This is a time-consuming and more expensive process due to the limited number of gears that can be processed in a single run.

The CNC machining process is ideal for producing precision tooth shapes with extremely high tolerances. Another aspect of CNC machining in gear production is broaching, which involves using broaching tools to cut out the shape of the teeth. As with all CNC machining, the broaching process can be programmed into CNC machine tools.

Surface Treatment of Double Spur Gear Plastic:


Plastic gears are lighter and more inert than metal ones. They can be used in environments where metal gears are prone to damage and degradation, such as water meters and chemical equipment control. Gears made of plastic generally do not require secondary machining, so a 50 to 90 percent cost reduction is guaranteed compared to stamped and machined metal gears.

Plastic Gears for Sale

A custom-made plastic gear can be used to transfer not only motion but also power. While spur gears were once the most common type of plastic gear, almost all types of gearing, including cylindrical worm, helical, and ring and pinion gears, are now manufactured.

We have a wide range of China plastic gears for sale that can be used in a variety of industrial and commercial applications. Our gears are made of high-quality plastic, so you can be sure they will last long and perform reliably. We also offer a variety of sizes and styles to choose from, so you can find the perfect gear for your needs.

Lubricating Plastic Gears

When lubricating plastic gears, it is essential to choose the right type of grease based on the tribological performance and material compatibility. Some factors to consider include the viscosity, NLGI class, base oil and type of thickener. These factors affect the lubricant’s efficiency and its compatibility with the plastic gears.

The first consideration when lubricating plastic gears is a lubricant’s compatibility with the plastic. If a gear is not compatible with a lubricant, it may deteriorate prematurely, causing cracks and pits in the gear’s surface. The base oil and additives used in the lubricant must be compatible with the gear’s surface, as well as the plastic itself.
