Nano-Level Gear Inspection Goes Smaller

May 2024, Rochester, New York (USA)

The 175GMS nano Gear Metrology System delivers ‘nano’ sub-micron level inspection capabilities to smaller gears, helping ensure minimal noise, greater precision, and longer life.

Based on the success of the 300GMS nano platform, Gleason has expanded its nano series with the introduction of the 175GMS nano Gear Metrology System. The 175GMS nano picks up where the very popular 175GMS leaves off. Like its predecessor, it is designed for the complete inspection of all types of gears as large as 175 mm in diameter and shaft-type gears up to 480 mm in length, maximum measurable tooth width of 340 mm, with a module range of 0.4 (optionally 0.15) to 6.35 mm. With this update, the measuring range of the 175GMS nano in the lower module range as well as in the capacity for shaft length and tooth width has been significantly extended. Furthermore, the 175GMS nano delivers the nano capabilities first offered with the 300GMS nano. The integrated probe changer automatically deploys a skidless probe to check the surface quality of gear teeth in the profile and lead at sub-micrometer precision. The skidless probe is optionally available with automatic angle setting to adapt to different helix angles of gears. The 175GMS nano Gear Metrology System is equipped with a high-precision SP25 3D scanning probe head, a wide range of styli, and an advanced mathematical analysis that supports roughness evaluations to DIN, ISO, ANSI and other standards. The latest GAMA™ software platform also performs gear noise analysis with the Advanced Waviness Analysis software tool. It also offers 3D measurement and GD&T analysis rivaling those of a CMM.

Like all the metrology systems in the Gleason GMS® series, the 175GMS nano seamlessly integrates into any user’s manufacturing ecosystem through use of Gleason’s latest GAMATM 3.2 software suite with its user-friendly interface supporting many different languages. Fully compatible with Windows, it effortlessly integrates into server environments, opening avenues for enhanced SPC data evaluation and remote maintenance services via Gleason Connect®, among others.

Through Gleason’s “Closed Loop” feature, users can take the connectivity of manufacturing and inspection to the next level. The 175GMS nano communicates inspection results directly to Gleason production machines, enabling automatic correction of machine settings. From Power Skiving to threaded wheel gear grinding, this synergy opens new horizons for quality production. Additionally, inspection results like topography measurements and order spectrum from Advanced Waviness Analysis software can be forwarded to KISSsoft® Design Software. In KISSsoft, the designer can see differences between the original design and the actual produced gear and evaluate variables such as the contact pattern in the final application under various load conditions. Noise behavior can then be predicted even before testing on a single flank tester or end of a line tester at final installation. This “Smart Loop” technology advantage holds the key to elevating gear designs faster and more seamlessly to a much higher level, for peak performance.

The 175GMS nano is optionally equipped with the patented Advanced Operator Pendant (AOP) enabling operators to record video and voice messages and to monitor environmental conditions. It may also be used to support remote maintenance via video telephony and can read bar and QR code information directly into the machine, for further use in inspection protocols or to select the appropriate inspection cycle.

As gear industries advance, so does the need for unparalleled precision. The 175GMS nano Gear Metrology System heralds the advent of a new era, where nano-level inspection is no longer the exception, but the rule. The 175GMS nano can be experienced live at IMTS and AMB shows in September 2024.
