Closed Loop Machining of Cylindrical Gears

Looking to raise the quality and accuracy of your gearing? Consider Closed Loop design and manufacturing, which has done away with the error-prone data transfer from the measuring sheet.

Leonhard Euler’s 1760 invention of making cylindrical gears with an involute profile was the beginning of a success story. As a tooth profile, the involute has many advantages that are still being used by engineers to design high-performance transmissions that even function under high loads and the consequential deformation of the shaft bearing system. However, […]

Fatigue Performance and Cleanliness of Carburizing Steels for Gears

This investigation shows that steels with a higher cleanliness level reach a higher performance level as well, both in terms of increased loads and longer service life.

The cleanliness of steels used for gears is of great importance when looking to improve their life or increase loads. In this paper, carburizing steels with the same basic chemical composition, but with a varying cleanliness level, are compared in regards to cleanliness and performance. Steel cleanliness can be described as size and frequency of […]

Extending gear life in demanding applications

Specialized PVD coatings increase the surface hardness and durability of gears, thereby increasing their lifespan under high-load conditions.

Although gears and other precision components are generally made of hardened steel or metal alloys, those used in high load applications still can fail due to excessive wear, surface fatigue, pitting, galling, and corrosion. This is exacerbated in applications with metal-to-metal interaction, repetitive friction at high speeds or where little to no lubrication is present. […]

Advanced Thermal Processing for Enhanced Gear Tribology

TriboNite technology can help improve gear performance by combining the well-known advantages of nitriding with the superior tribological performance profile of solid lubricant coatings.

By Boris Zhmud, Johan Blomkvist, and Mikael Fallström

Abstract Vast empirical knowledge accumulated over centuries, in conjunction with recent advances in the areas of material science, tribology, and big data analysis, have allowed significant progress in gear design. Still, gears sometimes fail. Gear tooth flanks are most vulnerable to damage under tribological stress. Gear material, machining, and finishing methods, lubricant, and end use […]

Oil Quenchants: Understanding the Chemistry (Part I)

This installment explores the chemistry of oil quenchants and the effects of additive packages on quenching performance, to be followed in February by a discussion of base oils.

Oil quenchants have been used extensively to harden steel in excess of 100 years. There are a wide variety of commercially available quenchants on the market, from nearly as many different producers. This column explores how the chemistry of the base oil and additive package affects quenching performance. A discussion of the mechanism of oil […]

Making the best selection

There are different types of gears to choose from depending on the orientation of the application.

In today’s online dating world, you are asked several pointed questions in order to determine your perfect match. Just like human relationships, gears work best when they are properly matched. In order to find the proper style of gear for an application, the first consideration needs to be what gear type will fit with the […]

Machinability and the Cost of Manufacturing Gears

Taking material modifications into consideration can play an important role in reducing overall machining costs. Here are some helpful tips.

When it comes to material-associated gear manufacturing costs, machining and gear-tooth cutting costs stand out as primary contributors. The gear blank and tooth machining costs are further dependent upon the machine tool/machining methods used and the associated cutting insert/tool. The interaction between the tools and the base material determines the life or number of parts […]
