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 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.
When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.
Quality control, EV components, energy consumption and material influences are just a handful of topics being discussed in heat treating today. New heat treat methods and global trends will be the topic of conversation later this year at Heat Treat 2023. Here’s a round-up of some stories circulating across key market segments.

Gleason Corporation’s Prof. Dr. Hermann J. Stadtfeld, Vice President of Bevel Gear Technology and R&D, has been awarded a new patent for his latest invention, “Psychoacoustic Tooth Flank Form Modification”—also known by its working name MicroForm. The innovation marks his 70th patented invention, continuing a career dedicated to advancing the science and manufacture of bevel gears. Gear Technology caught up with Dr. Stadtfeld to field a few questions about this latest milestone.
The KISSsoft System Module allows you to predefine virtually any possible combination of shifting positions and boundary setups in a transmission or gearbox. They are then combined into Operating Modes. These operating modes specify which clutches, switching elements, or brakes are active and which load is applied at specific system boundaries at a given situation. A typical example is when a gearbox is driven by multiple motors, like in a Dual Motor EV gearbox and different load combinations and/or power flow directions (changes from driving to coasting condition or from motor to generator mode) need to be analyzed.
