Company Profile: Ronson Gears

Proudly Australian with an international reputation for quality, Ronson Gears has become a market leader by thinking globally.

Gordon New likes to reminisce occasionally. “History can get forgotten if you’re not careful,” he said. “I remember my brother, Terry, and I going up to the factory when I was five and he was 10. We have fond memories of that time.” That was 60 years ago. Today, Melbourne, Australia’s Ronson Gears is making […]

ONLINE EXCLUSIVE: Helical or Not Helical? How Helical Gears Impact the Performance of Planetary Systems

A “one-size-fits-all” approach is seldom the optimal solution. The belief “helical is better” is not sustainable.

This paper explains the differences and the effects of zero-helix-angle and non-zero-helix-angle gears in planetary gear systems. As a conclusion, it points out that the belief “helical is better” is not sustainable. For lower noise and quieter run, helical gears have the advantage. If it comes to loadability, smaller size, and higher torque density, as […]

The Anatomy of a Lubrication Erosion Failure: Causation, Initiation, Progression, and Prevention: Part I

A discussion of detailed destructive metallurgical evaluations of a specific lubrication erosion failure, which the authors have conducted in order to analyze and characterize the failures.

Material science is the oldest of all science and engineering disciplines. It is not an overstatement to say that materials science has transformed human history. The Bronze Age and the Iron Age defined the rise and fall of complete civilizations. The economic might of the industrial revolution was built on the Age of Steel. During […]

Modernization of Main Helicopter Gearbox with Asymmetric Tooth Gears

Research and development of asymmetric tooth spur gears for modernization of the light multipurpose helicopter gearbox has amplified its load capacity to utilize more powerful turboshaft engines.

Application of asymmetric tooth gears for aerospace propulsion drives allows for considerably increased power transmission density, potentially increasing their load capacity and reducing size and weight. However, there are not many practical implementations of such gears. One such application of asymmetric gears in the turboprop engine gearbox is described in “Application of Gears with Asymmetric […]

The Dynamic Art of Gear Broaching

For this year’s broaching issue, Gear Solutions has enlisted two companies—Broaching Machine Specialties and Slater Tools—to offer insight into two very different types of broaching: conventional and rotary.

 

 

Conventional Broaching: Be a Broaching “1%-Er” By Matt Egrin, President Broaching Machine Specialties After giving a 15-minute plant tour of BMS to lay people, I often tell them at the end of the tour that they now know more about broaching than 99% of people in the world. I believe I can say that with […]

Nondestructive Testing and What Certification Fits Your Gear Production Needs

If nondestructive testing is a requirement of your gear production process, be sure to choose what best suits your product and your intent.

Nondestructive testing (NDT) is a fascinating and ever evolving field prevalent within the gear industry. It is because of this evolution that a need for standardization is warranted. This standardization can be achieved through a certification scheme that meets both your company and product’s needs. The two main certification systems, which I will describe in […]

Proper Spur and Helical Gear Inspection

A summary of the principles of gear inspection as they apply to spur and helical gearing.

In last month’s Tooth Tips, we studied finished and pre-finished gears, along with their profiles. Let’s move on to some more definitions useful in proper spur and helical gear inspection. Lead Crown: This is a gradually increasing metal removal from the mid face point on the tooth length to the ends of the tooth. Always […]

Heat treating is all about using the most cost-effective process

Gears come in all shapes and sizes, made by a myriad of methods: forged, cast, PM, etc. Virtually all methods require heat treating of some kind. When the cost of making gears is itemized by raw materials, machining, and heat treating, the greater quantity that can be made without interruption determines the individual cost. There’s […]

Hyperspecialization-The Ups and Downs of Doing One Thing Well

If you gathered all the people in the world who could explain how to broach an internal spline; or the influence of nitrogen on restricting austenite grain growth while heat treating a gear; or the pros and cons of using Barkhausen Noise Analysis; you would have a small (and probably strangely-dressed) crowd. “How many people could […]
