EVs are Driving Technology in the Gear Industry

May 22, 2023

A significant amount of work is being done to advance the technology of gears specifically for use in electric vehicles. No longer hidden by the noise of the internal combustion engine, the transmission has taken center stage as the noisiest component in most electric-driven cars.

Technology Advances for Continuous Generating Gear Grinding in EV and More

Meeting the challenges of gear grinding with innovative abrasive technology that improves gear efficiency and quality

May 22, 2023

Continuous generating cylindrical gear grinding is one of the most demanding grinding applications for automotive and aerospace manufacturers. To improve gear efficiency, gear life, and noise levels, gear profile tolerances and surface finish requirements are becoming more stringent. This is especially true for EV gears, which typically require lower noise characteristics than traditional automotive gears. These new quality requirements must be maintained without sacrificing cycle time, and without inducing grinding burn.

Noise Analysis for e-Drive Gears and In-Process Gear Inspection

Ensure optimum quality in a fraction of the time

May 22, 2023

Dr. Antoine Turich and Klaus Deininger

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.

Internal Gearing, Deburring, Honing and the Advancement of Robotic Cells

Examines the changing face of machine operation today

May 22, 2023

The electrification movement is in full swing despite many obstacles still in play. Regardless of these challenges, machine tool providers are expanding their machine operations and tooling capabilities to meet the e-mobility demands of the future.

Industrial Methods for Grinding Burnout Testing

Current state-of-the-art and developing trends

May 22, 2023

Martin W. Seidel, Antje Zösch, and Konstantin Härtel

When grinding steel parts, the surface of the part can "burn" if too much heat is applied in a short time. Grinding burn refers to all those structural changes in edge zones of steel parts that are caused by grinding processes in steels due to the thermal energy introduced. Grinding burn can mainly occur in the form of tempering zones or new hardening zones.

Test Rig for Crowned Spline Joints with Optimized Surface Treatments Under Misaligned Conditions

May 22, 2023

Gerrit Hellenbrand, Dieter Mevissen, Jens Brimmers, and Prof. D... Christian Brecher

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.

Force Modeling in Generating Gear Grinding Considering the Grinding Worm Topography

May 22, 2023

Patrícia de Oliveira Löhrer, Mareike Solf, Jens Brimmers, and Dr.-Ing. Thomas Bergs

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.

The Right to Repair

May 22, 2023

Next year, farmers in Colorado will be able to fix their own tractors, and manufacturers will have to provide them with resources to help them do it. In late April, Colorado became the first state to ensure farmers can work on their own equipment with Governor Jared Polis signing “The Consumer Right to Repair Agriculture Equipment Act,” which forces manufacturers to make available the necessary manuals, tools, parts, and software to farmers who rely on complex and expensive machinery, such as tractors, combines, and other farm equipment.
