Inspection and Measuring on Threaded Tools

The measuring machine, ThreadCheck, offers precision for complex geometries, automation, seamless documentation, and production integration.

Increasing product varieties, shortening of production cycles, and a growing demand on quality are just a few of today’s many production requirements. Flexibility is also necessary, as well as cost-effective solutions for efficient processes, optimization of setup times, and measurement solutions for new tools, materials, and processing technologies. With the demand for thread-cutting tools increasing […]

Precision Bevel Gears with Low Tooth Count

An analysis focused on the geometry and the kinematics of right-angle bevel gears with low tooth count shows that inequality of base pitches of the gear and mating pinion is the root cause of insufficient performance.

Right-angle bevel gears are a particular case of intersected-axis gearing (further Ia-gearing) with an arbitrary value of the shaft angle. Commonly, bevel gears with the base cone angle (Γb for the bevel gear and γb for the bevel pinion) larger than the root cone angle (Γf for the bevel gear and γf for the bevel […]

Case Study: Circle Gear and Machine Company and Pequea Machine Inc.

Two companies work together to bring the manufacturing process of gears and gear components back to the U.S. from overseas.

In a joint effort to bring manufacturing back to the U.S., also known as reshoring, a relationship was formed between gear manufacturer Circle Gear and Machine Company and agricultural machinery manufacturer Pequea Machine Inc. Today, both companies are reaping the rewards: Circle Gear has increased its capabilities and capacity, and Pequea is proud to market […]

Layout of the Gear Micro Geometry

A three-step methodology can be a successful approach to optimizing flank line and profile modifications.

The last phase in sizing a gear pair is to specify the flank line and profile modifications, also known as the micro geometry. To do so, it is first necessary to select the primary objective for which optimization has to be achieved: noise, service life, scuffing, micropitting, or efficiency. Certainly, it is not possible to […]

Streamlining Processes

While we should strive to make the best product, sometimes it’s best to heed the warning: just because you can, doesn’t mean you should.

In the gear manufacturing world, there are many ways to design and make gears. In the quest to compete, many companies are not satisfied with the minimum. Using the latest and greatest machine tools, we are able to hold tolerances that were unheard of 10 years ago. We cut and grind them, and then check […]

Heat-treat troubleshooting

The following discussion is not about six-sigma or even three-sigma practices. It focuses on my experience assisting a recent heat treater. The calls I receive for help are from experienced or novice heat treaters and sometimes even from those who have no experience at all. So, finding out why their furnaces are not producing the […]

Cost Savings
In the gear manufacturing industry, there are several ways to cut down on operating costs, including working with a custom gear manufacturer and purchasing high-quality equipment that will save on long-term costs.

In gear manufacturing, high-quality parts, machinery, and services are important elements to an efficient production process and a long-lasting end product. However, in an effort to provide the highest level of performance and reliability, costs can snowball quickly, whether you’re the customer or the manufacturer. It’s important to be aware of some key ways to […]

History of Bending Fatigue, Part VI

Knowing when a failure is likely to occur or being able to estimate a mean time to failure may be the most important analysis in mechanical and electrical engineering.

In the sixth and final part on the impending factors of fatigue design, we illustrate the process of Weibull failure analysis. In engineering, we usually want to create a predictive model of component failure to guide us in our design intent or to do conformation testing to validate the integrity of the actual invention. Fatigue […]
