At first glance, the gear industry might seem like a small industry, easily navigable for someone new to it. But it’s only small in terms of the number of people involved. In fact, once you’re in it, you quickly realize the gear industry is extremely broad.

Inspection Workholding: Simply Perfect

Gleason LeCount Adjustable Expanding Mandrels offer a fast, flexible and amazingly simple solution for metrology applications where speed, accuracy and repeatability are paramount

June 20, 2023

Keep it simple. More often than not it turns out to be the best course of action in life and on factory floors. Take, for example, Gleason LeCount Expanding Mandrels. You’ll find them in quality labs around the world, delivering reliable, repeatable workholding performance for the inspection of gears and other bore-type workpieces. Quality labs today are at the epicenter of the drive to produce increasingly complex, high-precision parts, while at the same time racing to take time and cost out of the inspection process. Counter-intuitively, perhaps, the best workholding solution to meet these ambitious new inspection requirements turns out not to be something new and more complex—but the simplest solution of all: Gleason LeCount Expanding Mandrels.

Corrected Lead Hobs

Understanding their use cases and machine settings

June 20, 2023

During our interactions with customers, we find the common challenge faced by customers about getting incorrect component parameters using corrected lead hobs. To address the challenge, we will talk about what corrected lead hobs are, why it is necessary to design such hobs, and how to set up the hob on the machine depending upon the type of hobbing machine (manual, semiautomatic CNC, or CNC).

The Future Looks Bright for the Gear Inspection Industry

Empowering quality through deeper precision

June 20, 2023

On the surface, it may not seem like the gear inspection industry has changed much over the last few years. Shops still primarily use either machines that are dedicated solely to measuring gears, or multiuse Coordinate Measuring Machines (CMMs). And regardless of which machine they use, software serves as the backbone that supports their many diverse sensors.

The Changing Face of the Off-Highway Drivetrain

Adapting to sustainable products, practices and technologies in the agricultural, construction and mobile equipment markets

June 20, 2023

If trade shows are still a major indicator of market growth, the construction and off-highway industries seem to be in a good place in 2023. CONEXPO-CONAGG and IFPE 2023 welcomed more than 139,000 attendees to Las Vegas in March. These visitors were treated to 2,400 exhibitors from 36 countries reaffirming the belief that innovation and sustainability will drive these markets in the coming years.

Results of ISO/TS 6336-22 Evaluating Full Contact Zone

June 20, 2023

Robin Olson, Mark Michaud, Jon Keller, and John B. Amendola

This investigation reviews calculations using ISO/TS 6336-22 Method A and Method B, comparing the calculations against field results. Extensive reviews were made of geometry, surface roughness, load conditions, and lubricant conditions to best understand the influences of micropitting on each example and the applicability of the calculations to the results.

Analytical Determination of Range of Number of Teeth in Generating Non-Involute Tooth Forms Using Fixed Reference Profiles

June 20, 2023

Igor Zarębski, Jarosław Górniak, Tadeusz Sałaciński, Adam Marciniec, and Paul St George

The toothed belt and pulley system known by the designation T, which has been selected as an example within this paper, was developed in the 1950s and standardized first in DIN 7721 (1977) and then in ISO 17396:2014. In this case study, the authors check if a single hob can properly cut T5 profile pulleys with 25 and 30 teeth—and if
so, define the range of the number of teeth covered by this hob.

The Mystery of Diesel Lost at Sea

A new historical book examines Rudolf Diesel

June 20, 2023

Gear Technology readers know diesel—because of the fuel’s properties, such as viscosity, lubricity, and combustion characteristics—can influence the design considerations for gears within the diesel engine. What our readers might not know is on September 30, 1913, The New York Times led with a headline that Rudolf Diesel—multimillionaire inventor of the diesel engine and international superstar in the scientific community—had disappeared from the passenger steamship, Dresden, crossing from Belgium to England and was presumed dead.
