Measuring Root/Flank Stress in Plastic Gears

This paper provides an overview of the testing procedure for plastic gears according to the VDI 2736-4.

The number of plastic gears used in different applications is increasing every year, mostly due to their cost effectiveness for large series production and lubrication-free running. With a rapid development of plastic materials in terms of strength and allowable temperature range, plastic gears are finding their way also into more demanding applications, where high transmittable […]

Fast, Flexible Bevel Gear Cutting

Companies interested in increasing capacity and agility to their precision gearing operations will be interested in the new Gleason bevel gear cutting, lapping, and testing machines. Here’s one company’s experience.
From Gear Solutions staff reports

Well over 100 bevel gear cutting machines crowded this Chicago factory floor just a few years ago, all busy producing spiral bevel gear sets by the thousands. Now those machines are gone. If you guessed that this is yet another example of a rust belt manufacturer losing its competitive edge, or shipping jobs offshore, you’d […]

Numerical Thermal 3D Modeling of Plastic Gearing

In this exercise, a numerical thermal 3D model is used to predict the surface and body temperature of spur and helical plastic gears.

This paper will primarily focus on the prediction of gear temperature of plastic gears using a numerical heat transfer model based on 3D Finite Difference (FDE) method. It is quite common that in most of the applications, the plastic gears are self-lubricated. Tooth surface wear is an important failure mode in plastic gears, and this […]

Contamination of polymer quenchants in induction hardening

Some think coolants or other contamination do not harm the quenchant. This perception couldn’t be farther from the truth.

Induction hardening is a common and effective method of achieving a hard, wear-resistant surface without carburizing or nitriding. It is used extensively to harden gear teeth, as well as wear surfaces. A compressive residual stress at the surface contributes to excellent fatigue resistance. Heating is rapid, and well suited for automation. The preferred process sequence […]

The Zen of Gear Design

Exploring the ‘hows and whys’ of choosing the proper center distance for your gearing requirements.

The feeling of Zen is one that we all can aspire to. Through practice and self-reflection, we can work toward being centered and grounded. Unfortunately for gears, too many designers overlook the need for gears to be properly centered. When set at the proper center distance, gears will mesh at the pitch point. In doing […]

Enhanced Steel Performance During Vacuum Carburizing of Gears

There are many benefits that can be gained from vacuum carburizing, but material selection is critical to producing a consistently high-quality carburized gear.

Many references cover the history and development of low-pressure carburizing, colloquially known as vacuum carburizing, so we’ll start our discussion with the motivations of gear manufacturers in choosing this process [1, 2]. The vacuum carburizing benefits commonly cited are the elimination of intergranular oxidation (IGO) for increased fatigue life, minimization/increased consistency in distortion response, elimination […]
