Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector. 

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.

From the outside, Gallmar Industries, nestled into an Oshkosh, WI, neighborhood, looks like any unassuming, medium-sized gear shop. Then take a plant tour with Gallmar’s VP of Operations Kenan Zolota—and prepare to be amazed. The facility stretches on like the Army’s warehouse at the end of Raiders of the Lost Ark, with everything from gear cutting to heat treat, gear grinding to inspection, all under one roof. Gallmar’s breadth of product line is in evidence too: defense-related transmission gears, 60-in. diameter internal gears for mining equipment, axle components for fire/ rescue trucks five feet in length, right down to a bin of brass ammunition casings that Zolota says are a special order.

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.

For the research developed in this work, an existing simulation model of the generating gear grinding process based on a penetration calculation approach is used. Further, an extension of the model considering a realistic modeling of the grinding worm topography and the macro movements of the grinding worm during the process is presented. The result of the simulation is the microinteraction characteristics throughout
the grinding of the gear flank. In the end, the information about microinteraction characteristics obtained will be used for the calculation of force and energy in generating gear grinding.

Tremec and Klingelnberg have been working together with regard to tool and gear measuring machines since 1993.  They recently collaborated on transmission technology with Speed Viper machine tools. 

Saint-Gobain Abrasives has introduced its new Norton Abrasive Process Solutions (APS) Program which was established to help customers determine the optimal grinding or finishing solution for the application at hand, ranging from simple to complex, off-hand or automated, and for metal fabrication, production grinding and virtually any abrasives operation.

Walter will introduce the latest addition to their machine lineup at the GrindingHub 2022 exhibition: the compact HELITRONIC G 200 tool grinding machine.
