Experimental proof of load carrying capacity, excitation behavior or efficiency is obligatory in the development process of most transmissions.

At Fraunhofer CMI, together with its partners at Fraunhofer IPT and WZL in Germany, the organization will help you to get the most out of your existing gear set. By applying innovative testing methods they are capable of analyzing the gear running behavior and producing custom optimization measures to your requirements.

“Our experience in manufacturing related gear properties and the utilization of validated calculation models enable us to predict and improve gear running behavior," said Marco Kampka, program manager at Fraunhofer Center for Manufacturing Innovation. "With this software based approach we can deliver the results you need in a timely and efficient manner. We are open to help you solve your challenges."

Gear testing includes investigation and optimization of gear acoustics, tooth root strength, scuffing analysis, gear efficiency measurement and optimization, planetary gear set dynamics as well as robust, tolerance-based gear design for spur and bevel (incl. hypoid) gears.

Test rigs include Dyno test rigs (acoustic measurements/efficiency measurements), Acoustic gear measuring cells (cylindrical gear measuring cell, planetary gear measuring cell and bevel gear measuring cell), mechanical back-to-back test rigs (load capacity tests, test rigs for standardized axis distances of a = 91.5 mm; 112.5 mm; 200 mm, variable center distances for industrial applications, oil tests: scuffing, micro pitting and pitting), analogous test rigs (pulsatory test rigs, two disc test rigs: friction coefficient and pitting strength) and CMMs and various inspection equipment.

Industries served include aerospace, automotive, industrial drives and wind turbine industry.
