Plastic Spur Gears

High quality Plastic spur gears from a China manufacturer,Feida Machinery.They are cylindrical gears with teeth parallel to gears axis, used to transfer motion and power between parallel shafts.

Basic parameters :

1. Module:It is the basic parameter determining gear size.The larger the module,the larger and stronger the teeth.
2. Number of teeth:It affects gear ratio and size.
3. Pressure angle:It affects root strength and is typically 20 degree.
4. Pitch circle:It is the reference circle used to calculate gear dimensions.
5.Addendum circle and dedendum circle:The gear’s outer circle and the circle at the bottom of the tooth spaces.

Main equipment:

Over the past few decades,Feida continuously introduces advanced production equipment and technical capabilities to meet the growing market demand and higher product quality requirements.The cnc machining equipment includes cnc lathe,cnc gear hobber, cnc gear shaper,cnc gear shaving machines, cnc gear grinder,cnc machining center,etc. The inspection instruments include mechanical test machine, material analysis spectrometer, coordinate measuring machines (CMM), roughness tester,hardness tester,etc.Thus,We are confident in supplying high precision  straight spur gears made of nylon,POM,PEEK to our clients.

Application:

Main plastic materials:They include nylon,POM,PEEK,etc.Different materials suit different working conditions.

1.Nylon features high impact resistance,excellent self-lubrication,and low cost.
2.POM features high rigidity,ultra-low friction coefficient(0.1-0.3),exceptional dimensional stability and shot molding cycles.
3.PEEK features extreme heat and chemical resistance,ultra-high strength/wear resistance and minimal creep,

Therefore,plastic(e.g.,nylon,POM,PEEK) spur gears are typically used in applications,including robotics,automotive industry,consumer electronics & home appliances,medical equipment,industrial equipment,food & packaging industry,aerospace,etc.

Certification & Packaging:

With a good reputation, strong technical strength, reliable product quality, high-quality service attitude, We won the trust of many customers at home & abroad.

To prevent finished products from rusting and being damaged during transportation, we will design appropriate packaging according to the product's shape, size, and intended use.

FAQ:

What are the advantages of plastic spur gears compared to metal spur gears?

The advantages include light weight,lower noise & vibration,self-lubrication,corrosion resistance,lower cost,etc.

What is injection molding?

Injection molding is a highly efficient manufacturing process for producing plastic parts in large volumes. In simple terms, it involves injecting molten plastic under high pressure into a precision-made mold, then cooling it and opening the mold to eject the finished part.

How do you handle for small batch/prototyping?

For small batch/prototyping,we typically use a gear hobbing machine or CNC milling machine to cut the gear from a plastic rod.
