New Developments in Gear Hobbing
Several innovations have been introduced to the gear manufacturing industry in recent years. In the case of gear hobbingâ€”the dry cutting technology and the ability to do it with powder-metallurgical HSSâ€”might be two of the most impressive ones. And the technology is still moving forward. The aim of this article is to present recent developments in the field of gear hobbing in conjunction with the latest improvements regarding tool materials, process technology and process integration.

High-Temperature Testing of Stanyl Plastic Gears: A Comparison with Tensile Fatigue Data
This paper shows an experimental study on the fatigue lifetime of high-heat polyamide (Stanyl) gears running in oil at 140°C. Based on previous works (Refs. 1â€“2), an analysis is made correcting for tooth bending and calculating actual root stresses. A comparison with tensile bar fatigue data for the same materials at 140°C shows that a good correlation exists between gear fatigue data and tensile bar fatigue data. This insight provides a solid basis for gear designers to design plastic gears using actual material data.
