Oil Quenching Technologies For Gears

In order to gain the benefits of oil quenching, you must understand all of the process variables involved. In the following, two heat—treat professionals share their expertise.

Oil quenching is a logical choice for gears. Atmosphere and vacuum carburizing carbonitriding of gears followed by oil quenching is a popular choice among manufacturers to achieve consistent mechanical and metallurgical properties and predictable distortion patterns. The reason oil quenching is so popular is due to its excellent performance results and stability over a broad […]

Diagnostic Tool Helps Develop Profile for Induction Hardening Process

A high-speed infrared camera with software to calibrate, freeze and record temperatures after each heat cycle is a diagnostic tool developing a process for profile hardening gears. The method can eliminate costly and most often destructive examination.

Combining process monitoring and a diagnostic tool to develop a process for contour (profile) hardening gear teeth or tooth-like objects on parts having gear-like geometry can eliminate costly and most often destructive quality checks. The process tool is an extension of the dual pulse induction hardening (DPIH) process. A high-value gear requires a hard wear-resistant […]

Superior Bearings for Extruder Gearboxes

Recent improvements have made spherical roller thrust bearings superior alternatives to the traditional bearing types used in output shaft applications. Here’s how—and why.

Demand for plastic components and materials in industrial and consumer applications is growing rapidly, and in all geographic regions. As demand increases, original-equipment manufacturers and their end-user customers are seeking new ways to improve the output and productivity of plastic extruder machines and extruder gearboxes. One potential solution involves greater use of spherical roller thrust […]

Terry McDonald: Site Safety

Familiarity can breed complacency, in our lives and in the workplace, so it's important to constantly seek out ways to stay focused on the job at hand, and to encourage employees to do the same.

I recently read an interesting article titled “Puncturing the Myth of World Class Safety.” It appeared in Industrial Safety & Hygiene News, and it endeavored to explain the meaning of “world class” safety. In doing so it came to the conclusion that claiming world class safety was mostly a marketing gimmick. The real truth is […]

Tooth cracks are often found to be a culprit when conducting a complete failure analysis

When conducting a complete failure analysis, tooth cracks are often found to be a culprit. The following installment discusses why this happens, and how it can be avoided.

Cracks originating in the surface of the tooth flank are due to Hertzian stressing at a depth relative to the maximum Hertz shear stress. The Hertz law provides the radius of contact between a sphere of elastic material and a surface in terms of the sphere’s radius, the normal force exerted on the sphere, and […]
