TOKYO, May 20 (Bernama-AsiaNet) — Polyplastics Co., Ltd., a leading global supplier of engineering thermoplastics, offers a range of design tips and techniques to help manufacturers reduce noise in helical gears made of polyoxymethylene (POM). Polyplastics is a leading global manufacturer of POM, under the DURACON (R) tradename, for diverse markets, including gears.

Among the design findings, it is generally believed that the tilt of the gear axis is an important consideration and its elimination will have a positive impact on noise issues. Polyplastics tried to verify that assumption, and actually focused on the skewed shaft angle (offset error). The company learned that noise does not necessarily worsen when the axis tilts.
