At the Control trade fair for quality assurance, Jenoptik offered a variety of automated measuring and inspection stations as well as new sensors and functions of the proven measurement technology for the target groups of automotive manufacturers and suppliers. Here are some highlights:
Complete inspection of gear surface finishes at the submicron level became a reality with the introduction of Gleason’s 300GMS nano, in 2022. The new system ushered in an exciting new era in gear inspection. For the first time, producers of EV transmission gears, and gears for other applications requiring very tight tolerances and low noise requirements, could quickly inspect surface finishes and perform extremely reliable noise analysis at submicron levels—benefits that were almost impossible to achieve just a few years ago.
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.
Gleason’s new 300GMS nano Gear Metrology System is built for today’s unprecedented transmission noise challenges and tooth form quality requirements. 300GMS nano delivers sub-micron analysis of tooth surface roughness after polish grinding; applies Advanced Waviness Analysis tools to detect and mitigate critical noise behavior caused by hard-to-find tooth form irregularities.
