Free Knowledge Served Daily

November 1, 2018

Technical articles have been the hallmark of Gear Technology since we first started publishing, more than 34 years ago, in 1984. One of the achievements Iâ??m most proud of is the development of the GT LIBRARY at geartechnology.com, where you can find every single one of those articles, going all the way back to the beginning.

Why Select Gear Grinding with cBN

November 1, 2018

Cubic Boron Nitride (cBN) abrasive wheels, which are a specially engineered abrasive grain referred to as a superabrasive, typically yield 2,200 - 2,500 parts per dress with one wheel lasting as long as four to six months.

The Influence of a Grinding Notch on the Gear Bending Strength Rating

November 1, 2018

To achieve the requested quality, most gears today are ground. The usual grinding process includes treating the gear flank but disengaging before reaching the root rounding area. If the gear is premanufactured with a tool without protuberance, then at the position where the grinding tool retracts from the flank a grinding notch in the tooth root area is produced. Such a notch may increase the bending stresses in the root area, thus reducing the strength rating.

Full Contact Analysis vs. Standard Load Capacity Calculation for Cylindrical Gears

November 1, 2018

In this paper local tooth contact analysis and standard calculation are used to determine the load capacity for the failure modes pitting, tooth root breakage, micropitting, and tooth flank fracture; analogies and differences between both approaches are shown. An example gearset is introduced to show the optimization potential that arises from using a combination of both methods. Difficulties in combining local approaches with standard methods are indicated. The example calculation demonstrates a valid possibility to optimize the gear design by using local tooth contact analysis while satisfying the requirement of documenting the load carrying capacity by standard calculations.

Regular readers of Gear Talk, our bi-weekly gear blog courtesy of Charles Schultz, know that he is extremely passionate about building an educational library and keeping detailed records in order to best transfer a companyâ??s gear knowledge from one generation to the next. While we adhere to this in the pages of Gear Technology, itâ??s worth noting that technical journals, magazines and 1,800 page bevel gear textbooks are not the only way to learn a little something about this great industry of ours.
