Optical vs. Tactile Gear Measurement for E-Mobility

A practical comparison of fringe projection and conventional tactile systems for classic and waviness gear characteristics

In this project, a practical measurement comparison of conventional tactile and optical systems was done. The goal was to investigate if and how good the measurement results of classic characteristics and waviness characteristics of the different physical measurement principles are comparable. In addition, it was determined whether the use of optical fringe projection measurement systems is suitable for gear metrology.

Investigating the Effects of Wear, Lubrication and Material Pairing on the NVH Performance of Plastic Gears

This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.

Design Principles of Bevel Gears: Rationale for Zero Sum Profile Shifts and Generating Gear Choices

This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.

Design

Thanks to material development and additive manufacturing opportunities, it’s important for the gear and power transmission industries to monitor the trends, technologies and future forecasts in the powder metal market.

Grinding

This article describes a cloud-based process and machine component monitoring system called ARGUS. The term “swarm” is used for a large population of gear-grinding machines of individual and independent customers connected to the ARGUS system and the ARGUS cloud. These “swarm” machines permanently feed their anonymized process data into a common cloud database. Reishauer uses this database for big data analytics to discover patterns that indicate successful process and machine component behavior patterns worth integrating into the ARGUS algorithms and propagate them across the complete ARGUS customer base.

Inspection

In conventional gear manufacturing, quality control is carried out for a number of pieces per batch. Most parts enter final gearbox assembly without any inspection. Among other things, this approach is based on two facts: measuring time is significantly longer than the machining time, and the limited measuring capacity available.

Heat Treating

Since I have had the privilege of visiting numerous gear plants and research centers in the U.S., as well as 170 in 33 countries, and I closely watch the progression of technology, I wanted to share my observations about some technological advancements. For the purpose of this article, I will focus on three key areas: Robotics, Machine Tools, and Heat Treating.
