The Benefits of Asymmetric Gears

A newly developed asymmetric gear tooth generating-grinding method combines maximum productivity with superior quality.

Gear wheels often rotate in only one  direction throughout their entire service lives. This applies particularly in the case of cars, commercial vehicles, ships, lifting gear, or generators. In the case of these gear drives, the tooth load on one flank is considerably higher than on the opposite one. This means that little or no […]

Polish Grinding of Gears for Higher Transmission Efficiency

A new gear polish grinding process is presented to show that improved surface finishes increase the overall efficiency of transmissions, and the resulting higher bearing ratios reduce micropitting. A cost-efficient manufacturing method adapted for large-scale manufacture is also introduced.

The established continuous generating method was used as the base technology for the polish grinding process, which is distinct from the vibratory superfinishing used in many non-automotive applications. Continuous generating grinding is an established process for the hard finishing of gears. Based on a dressable grinding worm, this process has proven itself, both in terms […]

State of the Art in Microstructure and Metallurgy Modeling

It’s important to understand the microstructure of forged parts in industries such as automotive and aerospace due to recent regulations, and simulation benefits are presented here to consider when working with rolled rings at different structure levels.

Anticipating the microstructure evolution during the manufacturing process has long been a major concern for specific industries such as aerospace. More recently, with the introduction of weight reduction regulations such as Corporate Average Fuel Economy (CAFE), the requirement to understand and control the microstructure of forged parts has permeated a number of other industries, more […]

Trend Talks: Training

Gear manufacturers and industry associations take on the responsibility of training the next generation of a qualified and skilled workforce.

Last month, I discussed the role that education plays in the gear manufacturing industry and provided examples of industry associations and companies that are on the forefront of driving the industry forward by developing an educated workforce. Similarly, training is crucial, and it goes hand-in-hand with educational opportunities both in the classroom and out on […]

Deep Nitriding for Gear Applications and Their Partial Treatments

Plasma/ion nitriding meets demanding gear applications by offering increased load capacity of gears and increased fatigue strength of components as well as less complicated masking treatments.

Stress conditions inside gear teeth are complex and require a careful examination by the designer before any specific surface treatment of the gears should be recommended [1]. As a result of those examinations, nitriding applications, specifically plasma/ion nitriding, for the surface engineering of gears have been growing steady in recent years because of the many […]

Wind Turbine Gear Repair

Due to the large installed base of wind turbines, demand for gearbox repairs has risen steadily in recent years. Isotropic superfinishing is an ideal process for repairing damaged gear flanks and bearing surfaces found on used wind turbine gears.

Wind turbine gearbox durability has improved significantly over the past ten years. The days of early gearbox failure due to epidemic micropitting are largely in the past. Improved gear design and manufacturing have made these gearboxes much more reliable. However, wind turbine gears remain expensive and are manufactured by a limited number of gear producers. […]

Variables for Quality Design: The Design Process

The final outcome of the gear design effort and how well it delivers the defined objectives is directly linked to the rigor of the design process.

In the April Tooth Tips column, we covered specifications — the second major element that dictates the ultimate accuracy of gearing and how well it satisfies the customer. In this column, we continue the series by taking a look at the third major component for quality design: the design process. Gearing Design Design, by its […]
