System-supplier Klingelnberg will be at AMB and IMTS in September, where it will be highlighting solutions for smooth-running gearboxes.

Every two years since 1982, AMB has presented the highlights of the international metalworking industry. This year, it will take place in Stuttgart, Germany from September 13-17. Klingelnberg will be at Booth C41. 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.

At IMTS, September 12-17 in Chicago, Klingelnberg will be at Booth #236935.

The electrification of the automobile has brought about a fundamental change in the design and quality requirements of a car’s drive train. The number of gears in the gearbox has been significantly reduced, while the noise behavior of the gearbox has gained even greater importance as a decisive quality characteristic. This has given rise to the requirement for 100 percent quality testing of the gears before they are installed in the gearbox, in order to minimize the number of complaints during end-of-line testing.

As a result, it is only logical to perform the gear inspection directly following hard finishing. The Klingelnberg production cell — consisting of the Cylindrical Gear Grinding Machine Speed Viper, the CompactLoader, and the integrated Cylindrical Gear Roll Testing Machine R 300 — is ideally suited for this purpose. The production cell can be equipped with all machine models in the Speed Viper series – from the Speed Viper 80² (dual spindle) to the Speed Viper 300.

Whatever the setup, the 100 percent quality inspection is always carried out with the Höfler Cylindrical Gear Roll Testing Machine R 300. With the R 300, all five known roll testing methods are optionally available. The inspection focuses on noise assessment, but on tests performed in single-flank contact: single-flank test, angular acceleration test, and structure- borne noise test. The quasistatic single-flank test provides a comparison to tooth contact analysis, the digital twin of the single-flank test. The result gives information about the quality of the gear geometry and correlates with pitch and tooth flank topography. The dynamic angular acceleration and structure-borne noise test procedures are an ideal complement to the single- flank test for evaluating noise quality.

The Klingelnberg production cell is the solution for the manufacture and 100 percent quality testing of high-precision gears for the electric drive train. With the optionally available R 300 production monitor, users always have a documented overview of the current key quality indicators in their operations.

Klingelnberg will also be presenting the tried-and-tested P 40 precision measuring center with hybrid metrology. Klingelnberg hybrid metrology is a smart combination of tactile and optical measuring technology. An optical sensor system developed specifically for gear measurement, as well as the rapid changeover between the 3D NANOSCAN tactile sensing system and the HiSpeed Optoscan optical sensor, enable flexible, fast, and highly precise measured value acquisition under all conditions.
