Plastic Internal Gear
A plastic internal gear is a gear whose internal components are composed of plastic. It is an alternative to steel gears for many applications.
Dimension: Φ3mm- Φ120mm
Module: M0.2
Material Type: POM PP PPT as customer required
Plastic Internal Gear
Plastic Internal Ring Gear
The structure of the plastic internal gear differs from the metal internal gear in several ways. The main difference is the internal gear seat, which is made of plastic material. This allows for a lower overall mass for the Plastic Internal Gear. Plastic pinions are not made of tooth-shaped transmission parts, so they are very simple and can be easily formed in the injection molding process.
The shaft of the plastic internal ring gear includes a stepped portion that engages a gear on its periphery. The stepped portion comprises two straight-edge sections and an inclined section. The rack moves along the channel as the gear turns, whereas the free end is free to move along the track.
Compared to metal gears, plastic internal gears are less expensive and do not require secondary finishing. Furthermore, due to the inherent properties of Plastic Gears, they can be made with greater precision. This represents a cost savings of fifty to ninety percent over their metal counterparts.

Features
- Internal Gear provides a compact parallel shaft transmission drive with considerable speed reduction.
- Plastic Internal gears are often used in applications involving planetary gear drives and gear couplings. There are three major types of planetary gear mechanisms: planetary, solar, and star types. Depending on the type and the pattern of shafts as input and output, many variations of speed transmission ratios and rotational directions are produced.
- Provided highly precision plastic internal gear.
- Offers ODM & OEM services.
