Calculation of Tooth Flank Fracture Load Capacity

Sophisticated methods for assessing the risk of tooth flank fracture have been available for a long time, but industry now demands simplified and standardized calculation methods.

1: Introduction Due to improved material qualities, new surface finishing methods and increased heat-treatment process reliability, flank surface damages, such as pitting or micropitting, can be prevented more and more in a reliable manner. This results in an increase of unexpected flank damages with crack initiation below the surface of the loaded gear flank(s), for […]

Advances in the Production of Double Helical Gears

Increasing demand for double helical gears in planetary reduction gear boxes for engines in civil aviation has necessitated a number of new capabilities and technologies.

Double helical gears (herringbone gears) are characterized by a symmetric arrangement of two identical gear teeth with exactly opposite helix angles. As a result of this symmetry, the axial forces in the gearbox negate each another. For many years, such double helical gears, as an example for components with geometrical interference, have been a special […]

Flexibility is Key to Aftermarket Success

An aftermarket business unit should look for solutions that marry technology with fresh green talent and bulletproof procedures as a model for achieving success.

Staying lean and profitable has always been a challenge for aftermarket gear manufacturing. Expedited delivery demands, legacy product support, unpredictable product volumes, limited warehouse space, and the expenses associated with keeping stored parts in sellable condition can make or break an aftermarket business plan. Supply chains and scheduling are chaotic at best, machine efficiency is […]

Surface finishing rotorcraft gearing

An analysis of a loss of lubrication test of Isotropic Superfinished gears without black oxide coating.

Rotorcraft gearboxes are designed with the utmost precision to withstand the tremendous demand and loads required to convert thousands of horsepower and RPM into hundreds of RPM and lift torque. These transmission components, and the lubricants used, incorporate various technologies to enable proper function and longevity. Many of these technologies are “tried and true” over […]

The benefits of converting to helical gearing

The introduction of a helix angle can change the performance of a spur gear.

The simplest-to-design and the easiest-to-use gearing design is that of the spur gear. It has teeth that are parallel to the shaft axis, and the center distance of a pair is easily defined. However, the introduction of an angling of the teeth, relative to the shaft center, will greatly change the performance of the gears. […]

Back to basics on heat-treatment of steel, underlying metallurgy

An ongoing discussion of the topic will begin with the Iron-Carbon phase diagram.

In this article, and future articles, we will discuss the basics of the heat-treatment of steel and the metallurgical reason behind it. We start off with the Iron-Carbon phase diagram. While many investigators examined the microstructure effects of temperature and steel, it wasn’t until Chernov in 1868 established that there are critical temperatures at which […]
