The newest edition of the Gear Research Institute (GRI) newsletter, “Transmissions” has been published.  The link below will guide you to the Newsletter posting on GRI's newly freshened website. Additional updates to the site will slowly continue to roll out.  

Zeiss and CleanControlling, a leading test laboratory for technical cleanliness, signed a cooperation agreement in April. The goal of the cooperation is to optimize products and industrial analysis techniques, and to set new market standards.

Intelligent power management company Eaton today announced that Ben Sheen, chief engineer, of Eaton’s Mobility Group, was recently elected to the Board of Trustees for the Gear Research Institute (GRI) at Penn State University. The GRI is affiliated with the American Society of Mechanical Engineers (ASME) and the American Gear Manufacturers Association (AGMA) to conduct research and development, consulting, and analysis for gear-related needs.  

A deep dive into the world of gear dynamics and gear noise has led many a mechanical engineer to Columbus, OH in search of the methods by which gear noise is measured and predicted as well as the techniques employed in gear noise and vibration reduction. Over the past 40+ years, about 2,550 engineers and technicians from 385+ companies have attended the Gear Dynamics and Gear Noise Short Course at The Ohio State University.

This investigation reviews calculations using ISO/TS 6336-22 Method A and Method B, comparing the calculations against field results. Extensive reviews were made of geometry, surface roughness, load conditions, and lubricant conditions to best understand the influences of micropitting on each example and the applicability of the calculations to the results.

In the present paper, a spline-joint design and the extension of a back-to-back test rig were presented, which enable the testing of crowned spline-joints under high rotational speed, medium torque, high test temperature, and angular misalignments.

The newest edition of the Gear Research Institute (GRI) newsletter, “Transmissions” has been published. The technical article included in this edition describes a recent experience where they encountered an unexpected surface quality issue during gear fabrication for one of their single-client projects. 

The idea of capturing the machining process, chip formation and the behavior of the metalworking fluid more precisely than ever before through photos and videos came about as part of a joint project with the renowned ETH Zurich. The research and development team at Swiss metalworking fluids experts, Blaser Swisslube, set about the planning and implementation. 

In its largest order to date, Danish wind turbine test specialist R&D Test Systems will develop the 30 MW powertrain and gearbox test bench for ZF Wind Power’s future “Test & Prototype Center” at Lommel, Belgium, that will house the world’s most powerful validation test bench for wind turbines. 

Exact Metrology recently exhibited at the Coordinate Metrology Society Conference (CMSC) with their sister division, OASIS Alignment Services: A Division of In-Place Machining Company.
