FEATURES

Affolter Technologies SA

Building upon its almost 100-year history of making small gears and pinions for Swiss watchmakers, today the company is manufacturing technologically advanced high-precision gear hobbing machines for micro-gear customers in a range of industries.

Affolter was founded in 1919 by Louis Affolter, making pinions and gear assemblies for local Swiss watch customers. In 1926, Louis expanded its capabilities and set up a workshop in a family apartment, sparking an almost 100-year tradition of keeping the company in the family. In 1946, Louis’ sons Andre, Rene, and Marc took over […]

Parametric Geometric Modeling of a Spur Gear Using SolidWorks

This study shows how the global equations tool and general calculation formulas in the SolidWorks application can be used to update a model just by modifying the spur gear number of teeth to reproduce a new gear with equivalent mechanical characteristics in simulation.

For a spur gear as a mechanical element, the design and sketching of the involute guarantees optimum functionality. This paper shows the parametric design of the generation of the involute tooth flanks with driven curves for a spur gear using SolidWorks. The full parametric design of the gear using the SolidWorks global equations tool and […]

Intelligent Process Monitoring Is Advancing Gear-making Productivity

A real-time tool monitoring system for gear hobbing machines has been developed and implemented in manufacturing plants to accurately detect and track tool wear through data collection and without changing process parameters.

Gear-making technology has been advancing at an extremely rapid pace. By many accounts, developments in tooling and machine technology have quadrupled productivity in the last 10 years. But that performance comes at a price, and the sophisticated tools and machines that make it possible are significantly more expensive than those used a decade ago. That […]

Influence of Contact Conditions on the Onset of Micropitting in Rolling-Sliding Contacts Pertinent to Gear Applications

Experimental results, obtained on a triple-disc micropitting rig under conditions designed to isolate the effects of the slide-roll ratio and specific film thickness, show that increasing the slide-roll ratio increases the extent of micropitting; however, the mechanisms responsible for this are not related to any potential effects of the slide-roll ratio on the prevalent film thickness, but rather to the increased number of asperity stress cycles at higher slide-roll ratios.

Micropitting is a type of surface damage that occurs in concentrated, rolling-sliding contacts, such as those between gear teeth, through rolling contact fatigue mechanisms. It differs from macropitting in that the damage initiates on the surface asperity level rather than the macro contact level. As such, micropitting is prevalent in contacts operating under low specific […]

Nitriding’s “White Layer” and Isotropic Superfinishing

Isotropic superfinishing is an ideal method of removing the problematic white layer created during the nitriding process.

Developed in the early 20th century, nitriding has evolved into a standard process across many industrial applications. Often considered the simplest technique for case hardening, the process is commonplace in aircraft manufacturing, bearings, automotive components, turbine generation systems, and various industrial machineries [1]. Modern practitioners have perfected nitriding into several sub-processes: gas nitriding (the most […]

Micropitting

Calculating EHL film thickness is one way that can help evaluate the relative risk of micropitting related to lubrication, which plays an important role.

Micropitting is a topic that has generated a lot of interest, discussion, research, and many technical papers in the last few years, but it remains a failure mode where much is unknown. There are many individual items that affect and are related to micropitting, such as oil film thickness, temperature, and the slide-to-roll ratio, but […]

Hot Seat: Hardenability

Factors that affect hardenability and the rate of austenite transformation — carbon content, grain size, and alloying elements — can be used to calculate hardenability for comparing alloy grades.

Steel is a mixture of iron, carbon from 0.0 to 1.2 percent, and alloying elements. Carbon provides the hardness, and the alloying elements provide how deep this hardness will occur. This concept is called “hardenability.” Hardenability should not be confused with the maximum hardness after quenching, which is only dependent on the amount of carbon […]
