In the AGMA system, the geometric parameters of the gear base circle are used as the basic control parameters. Indirect gear parameters such as radial pitch and pressure angle are used as working data and as reference standards in traditional analysis.

Gear rolling inspection can be considered as the best method to ensure consistency in the quality of injection molded industrial gears in batch production. It not only expresses the comprehensive total error (TCE) or one tooth comprehensive error (TTE) of the gear, but also determines whether the actual center distance between the measured gear and the measured gear is within the specified positive and negative tolerance zone. This provides a simple method to ensure consistency in daily production of injection molded industrial gears. For the statistical analysis of the rolling inspection results of a batch of sample gears, it can be determined whether the overall shape and absolute size of the gears are within the tolerance zone. For injection molded gears, rolling inspection is more like establishing a rolling inspection qualification verification, and it should be ensured that the injection molded gears produced every day meet this verification.

The development prospects of injection molded gears are quite optimistic. The materials are constantly undergoing significant improvements, and injection molding machinery is becoming increasingly precise. Testing equipment has been able to perform high-precision measurements on these unique injection molding gears. In the future, injection molded gears can be expected to replace metal gears in lighter load transmission applications. Manufacturers are continuing to search for applications and fields where metal gears cannot be used, but plastic gears have potential applications.

In order to enter these new potential application fields, it is necessary to correctly implement every step and explore every advantage of injection molded gears. The result is the development of a new generation of high-performance power transmission products.
