Gleason Corporation

Gleason Corporation celebrates its 150th anniversary with eyes intently set on the future of gear manufacturing.

Business survival horror stories begin one of two ways. A company either bets the farm on the latest tech trend or conceitedly refuses to adapt to an evolving market. Success stories are written by companies who build solid foundations on middle ground — embracing the advantages and dismissing the pitfalls of both extremes. Rochester, New […]

TOOLING & WORKHOLDING: Making the Most of G90’s Advantages

G90 material can be used to replace carbide in some hobbing applications. It can also provide increased production rates, increased tool life, or a combination of both of these when replacing traditional HSS hobs.

In his article, “Uncover Hidden Potentials in Hobbing,” which appeared in the June 2014 issue of Gear Solutions, Dr. Friedrich Momper explained how G90 — a new tooling material from Gleason — closes the performance gap between HSS materials and tungsten carbide. He also describes how the utilization of the G90 material can save up […]

High Temperature Vacuum Carburizing Drives Alloy Development

With gear surfaces, a growing demand for greater fatigue resistance can only be achieved by specialized heat treatments. Vacuum carburizing — low pressure carburizing — is a process that can be used to apply hardness, wear resistance, and increased fatigue life in specific parts.

Vacuum carburizing (low pressure carburizing, or LPC) is a process used to impart hardness, wear resistance and increased fatigue life in such applications. LPC is a treatment in which the steel component absorbs carbon liberated from a hydrocarbon gas into its surface at a low process pressure of 12 torr or less. New advanced alloys […]

Induction Hardening for Wind Turbine Bearing Rings

As installed capacity and component size continue to grow in the wind sector, induction hardening is a cost-and time-efficient method to meeting demand. As demand for gear rings and bearings increases, so will the need for more sophisticated induction hardening solutions.

It seems nothing  —  not even a worldwide financial crisis — can stop the rise of wind energy. The 2008-12 global recession did slow the sector’s growth — to the extent that 2013 resulted in the wind industry’s first-ever contraction (in terms of added capacity). But as figures from the Global Wind Energy Council (GWEC) […]

CASE STUDY: Cold Forming Technology, Inc., and West Michigan Spline, Inc.

Cold Forming Technology, Inc., and West Michigan Spline, Inc., chose to lead by example and show what happens when two similar companies opt for collaboration instead of competition.

Introduction John Donnelly, president of Cold Forming Technology, Inc., and Gary Hill, president and owner of West Michigan Spline, Inc., are known around the Rochester- and Lake Michigan-areas as collaborators in the spline rolling industry. However, getting to that point wasn’t easy. It took a great deal of trust building and a willingness to work […]

INSPECTION & METROLOGY: A Different Way to Look at Profile and Helix Inspection Results

The traditional inspection of involute gear profile and helix deviations results in plots of deviations from a perfect involute and from a perfect helix. While this is appropriate for gears with an unmodified profile or helix, it is not ideal for gears that have intentional modifications.

Introduction Elemental inspection of gears is commonly carried out with computer numerically controlled (CNC) machines. While these range from special purpose gear measuring machines with a precision rotary table to three-axis coordinate measuring machines (CMM) with software adapted for gear measurement, what these inspection machines have in common is they produce graphical output that shows […]

INSPECTION & METROLOGY: The Benefits of Using Tapered-Tooth Master Plugs (TMPs) with Spline Gauges

There is both a cost-effective and timesaving approach to evaluating the quality condition of a spline ring gage — the simple-to-use Tapered-Tooth Master Plug (TMP). This concept has been around for many years, but not everyone is aware of its benefits or how it works.

Eliminating unnecessary expenses is a very important factor in running a successful business. At first glance, it might seem unnecessary to purchase a gage that does not actually measure a component, but if you understand the true value in using tapered-tooth master plugs (TMPs) and how they assist the production process, then you can find […]

TOOLING & WORKHOLDING: Large and Small Gear Processing Reaps Benefits from Modern Workholding Synergies

As demand for higher-quality precision gears continues to rise, so does the need for high-quality gear manufacturing machines that can get the job done and skilled machinists who can properly operate the equipment.

Gears — both large and small — have similar issues when it comes to manufacturing. Whether that means high volume and low mix or high mix and low volume, setup time and part quality remain constant. Over the past several years, great strides have been made with gear-manufacturing machines as the demand for more precision […]

History of Bending Fatigue, Part IV

When analyzing gear tooth bending fatigue, keep in mind that the influence of frequency on the gears cannot be underestimated and natural frequencies should be avoided all together.

The influence of frequency for monotonic or reversing load applications should not be underestimated. Natural frequencies must clearly be avoided. In single tooth fatigue tests (as seen in Figure 1), the oscillation load is usually located at the high point of single tooth contact. Frequency of the input wave is such that, depending on material, […]

How To Find Qualified Employees

Finding qualified employees isn’t an easy task, especially in the gear manufacturing industry, and there are several key factors to keep in mind when searching for the best addition to your staff.

Wouldn’t it be great if when you needed to hire some employees, you put an advertisement in the paper and 100 qualified candidates lined up outside your front door? Well here on planet Earth, in 2015, it doesn’t happen quite like that. Most manufacturing companies — especially gear manufacturers — are struggling to hire quality […]

Metal alternatives — ceramics and ceramic composites — are achieving real-world applications

Ever since iron-bearing meteorites were discovered on earth, metal has been the material of choice for making almost anything requiring greater strength than wood. Raw materials, those found by mining or direct discovery, require manipulation of some kind — whether by heat, mechanical forming, or chemical reaction. Aluminum is a case-in-point. Mined from a narrow […]

Trend Talks: Anna Claire Howard

Maintaining a high level of quality in gear production relies heavily on the governing industry standard. However, adhering to that standard is optional.

In an industry as competitive and quality-oriented as gear manufacturing, meeting the latest and greatest industry standard and sporting a seal of certification on your company’s website may be just what you need to rise above the competition. Leading standard development organizations such as the International Organization for Standardization (ISO), the American Gear Manufacturers Association […]
