Optimization of Power Density by Local Gear Failure Modeling - March 2019

Marco Kampka, Christian Brecher and Christoph Löpenhaus

The article "Optimization of Power Density by Local Gear Failure Modeling" appeared in the March 2019 issue of Power Transmission Engineering.

Summary
Power density is a key factor in gear design. Increasing the power density enables engineers to use smaller gears for their applications which lead to smaller and lighter gear boxes. The benefit for example for the automotive industry is less moving load in the vehicles and therefor a reduction of fuel consumption and subsequently a reduction of CO2 emission. The limiting factor for the increase in power density of gears is the material strength in regard to the critical failure mode.
