IMTS 2024 Will Be Here Before We Know It

A preliminary look at the Gear Generation sector

July 23, 2024

The International Manufacturing Technology Show (IMTS) September 9–14 at Chicago’s McCormick Place is fast approaching and, for newcomers and veterans alike, it is always worthwhile to plan as much as possible in advance to make the most of it. For Gear Technology readers looking for gear manufacturing equipment such as gear cutting, forming, and finishing, as well as broaching, shaping, and slotting machines, you must first visit the Gear Generation sector in the North Building, Level 3.

Understanding Bevel Gear Grinding

Key techniques for optimal surface finish and gear quality

July 23, 2024

Spencer Artz and Josh Fairley

The world of bevel gear grinding is a complex topic. How do you determine which grinding and dressing parameters to select for a desired surface finish? What type of grinding wheel should be used? What type of dresser should be used? How do all these factors affect the gear noise and quality levels? These are some questions that will be addressed in this article.

Radial Chamfering Arrives for E-Drive Gears

Horizontal hobbing makes an ideal solution for geared shafts with interfering contours, including EV transmission shafts

July 23, 2024

Gottfried Klein

Manufacturers of EV drive systems are leaving no stone unturned in their quest for quiet-running, dependable transmission gears and shafts. Where once chamfering and deburring operations were almost an afterthought, they’re now considered a primary soft machining process, with widespread recognition that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise.

Bevel Gear Speed Increasers

July 23, 2024

Dr. Hermann J. Stadtfeld

For cylindrical gears, speed-increasing transmission stages are well known, and regarding profile shift, preferred pressure angles, and helix angles a set of rules applies, which is not much different from the rules for speed reducers. It is important to acknowledge that basically, a speed increaser has to be designed just like a speed reducer, but then the gear with the lower number of teeth is the output. Of course, the torque and the speed of the gear with the lower number of teeth (output) and the gear with the higher number of teeth (input) must be the same as if this transmission was used as a speed reducer. In the case of straight bevel gears, spiral bevel gears, and hypoid gears the same rules apply with some additions. Spiral bevel gears have many applications as speed increasers.

Hard Skiving of an Internal DIN5480 Spline—A Process Analysis

July 23, 2024

Dr.-Ing. Thomas Glaser and Jochen Sapparth

This report uses an application case to demonstrate the optimization potential of gear skiving in the production of internal splines on a universal machining center. The process established in the example is then analyzed using the software tool OpenSkiving developed by the wbk Institute of Production Science of the Karlsruhe Institute of Technology (KIT) and the results are discussed. Finally, the most important findings are summarized.

The Long Now

July 23, 2024

The 10,000-Year Clock, also known as the Clock of the Long Now, is a visionary project aimed at fostering long-term thinking and responsibility. Located inside a mountain in West Texas on land owned by Jeff Bezos, this clock is designed to keep accurate time for 10,000 years, serving as a powerful symbol of longevity and sustainability.

Siemens Software Automatically Identifies Vulnerable Production Assets

May 10, 2024

Adelbert Haas Offers Single Machining Operation for Aviation Components

July 23, 2024

The Curvic coupling from the aviation sector is a critical component used in helicopters. Previously, the external helical gearing was manufactured on one machine and the curvic coupling gearing on a second machine. The external and internal cylindrical grinding was then carried out on a third machine in two consecutive process steps.
