Optimizing Ring Gear Forging

The objective of this research was to develop an optimum preform/blocker forge geometry for a ring gear blank, which would minimize material usage and...

The Principles of Workholding: Part III

To conclude our three-part series on the principles of workholding we will begin with an overview of inspection devices, both hydraulic and mechanical. Next...

A Hard Turn Toward Efficiency

Since its broader introduction in the mid 1980s hard part turning has evolved considerably as a machining process. Developments of machinery, component material, hardening...

Workholding That Works

Like most manufactures, gear manufacturers today find themselves with the challenge of maintaining viability, maximizing profits, and enhancing productivity. Most are also experiencing varying...

Hard Fact of Hard Rack Milling

Rack gears used for rack and pinion assembly are often hardened to increase durability. In most cases a finish grinding process is necessary for...

Better Broaching through Process Control

Is your broaching process capable and predictable? Many are not. This article will discuss why and how performance metric based management can help bring...

Protecting Gears in Wind Power Applications

In wind power stations, both fluid (lubricating oils) and consistent (lubricating greases) lubricants are used. The main task of the lubricant is to ensure...

SKF Keeps Wind Turbines Spinning

The signing of a contract for more than 5,000 sets of SKF’s latest high capacity cylindrical roller bearings (HCCRB) for wind turbines will give...

Gearing Up for Land, Sea, and Air

As with many other industries, ongoing advancements in the precision gear industry are bringing about a paradigm shift in the way gearing products are...

Investigating Epicyclic Gear Whine

Gear whine is a major source of unwanted noise in automotive applications. It is tonal in nature, which makes it more apparent to the...

Higher Contact Ratios for Quieter Gears

Low-noise behavior in standard industrial gear units is becoming an important selection criterion and a factor indicating gear quality to the customer. In several...

The Principles of Workholding: Part II

This is the second installment of a series of articles devoted to presenting and/or introducing the various designs — and principles behind the design...

Tooth-Bending Effects in Plastic Spur Gears

This paper describes the investigation of a steel-plastic gear transmission, using both numerical (FE) and analytical methods. The aim was to study the influence...

The Next Frontier in Gear Testing

Having pioneered the science of polymer gearing, Kleiss Gears continues to focus on improving the state of the art. In past articles we have...

Predicting Hypoidcontact Conditions

Problems are often encountered in the design of automotive drive axles, since hypoid gear sets are very sensitive to the precise contact conditions. Assembling...

The Power of Pulsed Plasma

There has been much discussion regarding the surface treatment of gear power transmission systems using the nitriding process. Much of the past discussions have...

Powder Metal for Precision and Performance

While the powder metal process is becoming increasingly popular with gear designers because it is a cost-effective alternative to traditional manufacturing processes, the powder...

The Flexibility of Spindle Finishing

In recent years, an increasing degree of specialization in the metalworking industry has created a need for equipment that can meet complex finishing and...

Overcoming the Chamfering Technology Impasse

While the gear-making industry has seen many technology advances with respect to the sophistication of other necessary equipment, the process of gear chamfering in...

Epicyclic Gearing: A Handbook

Recent articles in Gear Solutions have discussed epicyclic gearing, but often in the context of experienced engineers. As more and more of these engineers...
