Pre-Nitriding: A Means of Significantly Increasing Carburizing Throughput

Pre-nitriding is a technology that addresses grain growth and creates a finer grain structure in the carburized case at higher temperatures. Case studies show how carburizing productivity has doubled, and sometimes tripled, using pre-nitriding.

Carburizing is a surface-hardening method that uses heated metal in a carbon-rich environment to increase carbon levels on the metal, via diffusion, for added hardness. Power transmission parts (gear boxes, gears, shafts, etc.) are a good example of components that benefit from carburizing. Traditional/endothermic (“endo”) atmosphere carburizing, which takes place in a controlled atmosphere, has […]

Comparison of Tooth Interior Fatigue Fracture Load Capacity to Standardized Gear Failure Modes

A comparison of tooth interior fatigue fracture load capacity with the predicted bending and pitting fatigue capacities, as calculated according to standards. Effects of several methods that can be used to mitigate TIFF risk are evaluated based on their performance, with respect to the other failure modes.

Introduction Gears are case hardened to produce residual stresses at the surface — improving wear resistance, bending fatigue, and contact fatigue strength. These beneficial compressive stresses are balanced by tensile stresses within the core. This poses an increased risk of fatigue crack growth below the surface. Both tooth interior fatigue fracture (TIFF) and tooth flank […]

Turning to Rolling Bearings for Industrial Gearboxes

Understanding the pros and cons of bearing types for industrial gearboxes and monitoring bearings once in service can help contribute to successful application outcomes.

Rolling bearings play vital roles in supporting the shafts and gear wheels of industrial gearboxes and, often, several different bearing types will function in one gearbox. Even when these precision components are properly designed, manufactured, and specified, however, effectiveness and service life can be threatened at every turn. Over time, the performance of a bearing […]

INSPECTION & METROLOGY: Investing in Yourself

Self-improvement and further education are necessary tools when it comes to succeeding in the gear industry.

Everyone should make an effort to improve themselves. One of the best ways this can be done is through education. This allows growth, which makes education a personal investment. After all, knowledge is one thing no one can take away. It is a self-promotion, and it benefits us all. Learning is also invaluable since it […]

INSPECTION & METROLOGY: The Payoff from Deploying Smart Gear Inspection Systems

Image 1: This diagram illustrates a simple gear process with key measurement gages indicated. A quality-control plan for parallel-axis gear manufacturing requires significant investment in analytical and functional inspection equipment, labor, and production cost. Minimizing these costs requires a good plan. Moving the analytical inspection equipment closer to the manufacturing location has consequences that can […]

TOOLING & WORKHOLDING: Larry McMillan

Great Lakes regional sales manager for Hainbuch America Workholding Technology

  How did Hainbuch get started? It’s a very innovative company that’s been in business since 1951. It started out making replacement collets. And that kind of grew and grew. Mr. Gerhart Rall, Mr. Hainbuch’s son-in-law, came on board to help Mr. Hainbuch run the company. And he was active in the first development of […]

TOOLING & WORKHOLDING: The Perfect Symbiosis

Modern thinking has shown that machine tools and tooling can’t be seen as separate entities.

The Swiss company, Reishauer, has shaped industrial history since its foundation in 1788. Originally, the company was set up as a smithy to make hand tools. In 1863, a “taps-lathe” was built to make the first threading taps with a radial relieving unit. With the growth of the tap market share, the company was well […]

Moving Forward as the Diablo Team
Diablo Furnaces

What are the origins of the Diablo team? Most Diablo employees worked in some capacity at BeaverMatic Heat Treating in Rockford, Illinois, before it closed approximately two years ago. Their roles have expanded here, because we do multiple tasks or wear several hats. Rick Claeyssen was basically superintendent, and at Diablo, he also runs the […]

Power Density; Why Steel Cleanness Matters

The recent development of cleaner air-melted steel provides design engineers the opportunity to embrace the power-density concept for their component applications.

As early as the mid-1980s, the concept of mechanical“power density” was introduced based, in part, on the use of clean steel. Today, the demands being made on a new generation of mechanical power transmission systems appear to be leading to an ever-increasing emphasis on “power dense” designs that offer higher power throughput via smaller system […]

A Brief Overview Of Splines

Splines must be properly sized and designed in order to ensure the proper torque capacity and operation.

Splines provide a connection between two shafts or other components that transmit torque and rotation. Splines may be straight sided, tapered, or have an involute form. We will only be considering involute splines here because they are much more common. Involute splines have teeth similar to gear teeth except spline teeth are much shorter, and […]

Heat Treatment of AISI 52100 For Bearing Applications

Manufacturing a component is oftentimes extremely complex, even when that component seems as simple as a bearing.

Bearings are crucial to our industrial life. They are found in virtually all industrial applications from wind bearings to aircraft engines. They are found in toys such as figits and bicycles, as well as automotive applications in engines and transmissions. Bearings allow parts to rotate in contact with another part with very low friction. Bearings […]
