Modernizing with Purpose

Liebherr gantry systems fuel Ford’s EV ambitions in Europe

E-mobility is taking hold around the world, and the automotive industry is changing. Many manufacturers are shifting from internal combustion engines to electric powertrains. The Ford Motor Company—a long-term partner of Liebherr-Verzahntechnik GmbH—will be making most of the electric drive units for its European production at its UK transmission plant at Halewood near Liverpool. As before, Ford will be using Liebherr gantry technology, but for electric drive units rather than transmissions for internal combustion engines.

Durability and Performance Rating Procedures for Plastic Gears

High-performance plastic gears are increasingly replacing metal gears in several applications due to the many advantages they exhibit. The main ones are lower weight, no need for lubrication, cheaper mass production, significantly better noise, vibration and harshness (NVH) behavior and chemical/corrosion resistance. Most plastic gears are produced by injection molding, which enables great design flexibility, e.g., joining several machine elements into one molded part, while gear geometry modifications like enlarged root rounding or altered profile shapes are also possible (Ref. 1).

The Role of In-Situ Techniques in Microstructure Optimization of Interstitially Alloyed Steels

Various in-situ methods can track realtime heat treatment response in bulk materials. This can aid material engineers in designing the most effective heat treatment procedures and processing methods. In-situ  methods such as thermogravimetry (TG), differential thermal analysis (DTA), and dilatometry, offer capabilities to examine heat treatment behavior in real time, giving insight into the thermochemical mechanisms and the thermal behavior of steel.

Design

As a community, we gear engineers collaborate and share ideas to progress our collective capability. Technology progresses based on our efforts, and we have seen solid advances in the performance of our products as they become quieter, cheaper, more efficient, and more power dense. The pages of this magazine (past and present editions) are filled with examples where talented engineers have dug deeper into a subject using a more precise approach to a particular area concerning gear performance. The implied belief is always that greater precision (complexity) in the calculations brings greater accuracy (alignment with reality).

Grinding

Cylindrical grinding is an essential machining process in precision manufacturing, ensuring that components meet stringent tolerances with superior surface finishes. Optimizing this process involves a strategic approach to wheel selection, process automation, in-process measurement and machine maintenance. This article explores key technical factors that influence the efficiency and accuracy of cylindrical grinding operations.

NVH

The arrival of Gleason’s Hard Finishing Cell (HFC) in 2018 represented a paradigm shift in the way automotive transmission gears and gears for e-drives, could be produced in high volumes. Now, for the first time, 100 percent inspection of every gear, and every gear tooth was possible in-process, without impacting the high speeds at which these gears need to be hard finished. Identifying, and correcting for, conditions that create unacceptable noise behavior in these gears, on the fly, was finally a reality too.

Heat Treating

Press quenching is a tried-and-true process for the controlled hardening of flat, circular close tolerance parts. The process ensures good dimensional control and uniform hardening, thus allowing for seamless processing post heat treatment.
