In this latest edition, issue 9, of the GEARS inline Customer Magazine, Klingelnberg once again presents all sorts of trends and innovations from the world of gears. This time, the machine manufacturer focuses primarily on the hot topic of noise behavior and analysis.
System-supplier Klingelnberg will be back at AMB (Booth C41, Hall 5), where it will be highlighting solutions for smooth-running gearboxes. The exhibit will feature the Höfler Cylindrical Gear Grinding Machine Speed Viper, the Klingelnberg Precision Measuring Center P 40 and the newly developed Höfler Cylindrical Gear Roll Testing Machine R 300.
When it comes to an early identification of noise problems in the drivetrain one has to take data analytics and its integration in the manufacturing process into account. The big vision here, in particular, is preventive quality. By evaluating sensor data of the machining process, it promises to predict whether a gear is ok or not ok.
Klingelnberg has developed a new precision measuring center. The P 152 is the latest addition to the family of Klingelnberg precision measuring centers. It is capable of measuring components with a maximum outside diameter of 1,520 mm and workpiece weights up to 8,000 kg with the usual precision.
Different component characteristics in electric vehicles lead to higher noise and load requirements in the automotive industry. E-mobility—to a certain degree—is changing how gear analysis and inspection is carried out. Dissecting noise issues in gears and gearboxes requires an analytical approach like a detective. The problem could stem from the design itself, tolerancing or tip/root relief issues, tooth flank form deviations like waviness or perhaps crowning issues that directly impact noise. Every aspect of gear production needs to be examined to provide the most accurate results.
Within the last decade, hard finishing technologies become highly relevant. Increasing the power density of a gearbox requires precisely machined gears without heat distortions. Especially in noise-sensitive applications, both honing and grinding are often applied.
