An Interview with Delrin at the VDI Conference on Gears 2023

While I was attending the 10th International VDI Conference on Gears 2023—held in Garching, Munich at the Gear Research Center (FZG) of the Technical University of Munich from September 13th to 15th, 2023—Delrin, a product family of DuPont, introduced a new high molecular weight nucleated resin specially formulated for use in applications requiring high creep resistance and fatigue durability. I had the good fortune to sit down and speak with Guillaume Doy, Global Marketing Leader from Delrin, to hear more about their acetal homopolymer for high-load mechanical applications.

Solvay Specialty Polymers for High-Performance Plastic Gears

Solvay, observing key trends and factors affecting the transportation sector, has developed, tested, and applied materials for a wide variety of automotive uses. Central to those objectives are efficiency and regulatory targets, engine size reduction, increased electrification of the powertrain, low NVH, and higher efficiency through lightweighting. It’s no longer a question of whether high-performance plastics are meeting NVH and other challenges in e-mobility environments, but which polymers are good for high-performance gears?

Optimizing Plastic Gear Geometry: An Inroduction to Gear Optimization

There are numerous engineering evaluations required to design gear sets for optimum performance with regard to torque capacity, noise, size and cost. How much cost savings and added gear performance is available through optimization? Cost savings of 10% to 30% and 100% added capacity are not unusual. The contrast is more pronounced if the original design was prone to failure and not fit for function.

Alternative Lubrication Methods for Large Open Gear Drives

The type of lubricant and the method of applying it to the tooth flanks of large open gears is very important from the point of view of lubrication technology and maintenance. When selecting the type of lubricant and the application method, it is important to check whether it is possible to feed the required lubricant quantity to the load-carrying tooth flanks, This is necessary to avoid deficient lubrication, damage to the gear and operational malfunctions. It is important to determine the type of lubricant, which may be fluid or grease-like. The consistency of the lubricant will have a direct impact on the ability of the lubrication system to feed adequately the lubricant to the gear. The interactions between the common types of lubricant and the lubrication application methods for open gear drives are shown in Fig. 1.

Plastic Gear Design Basics

Plastic gears are serious alternatives to traditional metal gears in a wide variety of applications. The use of plastic gears has expanded from low-power, precision motion transmission into more demanding power transmission applications. As designers push the limits of acceptable plastic gear applications, more is learned about the behavior of plastics in gearing and how to take advantage of their unique characteristics.
