Company Profile: Liebherr Gear Technology, Inc.

In the post-WWII landscape of Germany, the foundation of Liebherr was laid in 1949 on an invention borne out of necessity.

Liebherr began its storied history in a tumultuous time and place: Germany, 1949. At the time, Germany was in desperate need of equipment to speed up work on construction sites after WWII. The company was founded by a building contractor, Hans Liebherr, who had invented a tower crane to aid in the rebuilding of destroyed […]

Validation of a Model of the NREL Gearbox Reliability Collaborative Wind Turbine Gearbox

Manufacturers, engineering consultants, and gear and bearing software providers are part of a program to model, build, simulate, and test gearboxes with a goal to improve reliability and reduce the cost of energy.

Wind power has grown to be an important part of the energy mix in the U.S. In 2012 alone, the U.S. installed 13,131MW of wind power capacity, eclipsing the 60GW milestone and accounting for 42% of new power installations. [American Wind Energy Association] The state with the largest installed capacity, Texas, can sometimes generate over […]

Dynamic Analysis of a Cycloidal Gearbox Using Finite Element Method

A discussion of the stress distribution, modeled in a dynamic simulation environment, on the rotating parts of cycloidal reducer.

The cycloidal style of speed reducer is commonly used in many industrial power transmission applications. This type of mechanism, known for its high torque density and extreme shock load capacity, incorporates a unique reduction mechanism, which is different from that of the more commonly understood involute gearing. To recognize the technical benefits of the cycloidal […]

Good Things Need Some Time

It began more than 100 years ago: The story of skiving.

On March 1st, 1910, Wilhelm von Pittler registered a patent that was to revolutionize the manufacture of internal gears. His patent for skiving, with the title, “Procedure for the Cutting of Internal Gears by Means of an Internal Gear-like Cutting Tool on Which the Faces of the Teeth are Provided with Cutting Edges,” was initially […]

AGMA’s Wealth of Resources II

Joe Franklin explains that AGMA is a catalyst, a non-competitive environment for people to meet and develop the best standards they can, documenting best business practices in the process.

In the depths of the recession that started in 2008, there were a lot of questions surrounding Gear Expo 2009. While the show featured plenty of exhibitors and all the usual “buzz,” the show promoters had no idea how many people were going to attend. Consider the circumstances: The gear industry was on its back. […]

Meeting the Challenges of Measuring Large Parts

Manufacturers of large gear inspection equipment have to meet a number of new challenges with respect to physical size, moving masses, and thermal effects.

Overall Equipment Layout Even though the measuring principles on very large equipment are the same or similar to small ones, it would be wrong to expect identical assemblies with simply larger dimensions. Before going into detail, the following illustration shows the main assemblies of a large state-of-the-art gear inspection machine: Figure 1 Legend: 1. Z-Column    […]

Selecting the Best Application Combination

With an enormous assortment of material grades and a wide variety of metalworking processes available, the selection process for the best combination can be challenging for any application.

While large heat-treated components will always contain some stress, these stresses can be minimized in order to reduce the likelihood of catastrophic failure while still obtaining mechanical properties. An added benefit to this approach is increased throughput, lowered asset constraints, and increased safety. I’d like to devote this first column to defining some of the […]

Gear Accuracy Vs. Manufacturing Costs

When laying out the sequence of operations, the teeth must run true with the diameters and faces that will be used for their actual mounting.

The required gear accuracy is directly related to the costs of manufacture. The highest accuracy available by current processes is considered to be AGMA 15 (A2). On a 6-inch diameter gear, this is accuracy in the order of 0.00011″. There is also a limit on how wide tolerances can be to be economical. For example, […]

Three barriers prevent the state of perfectly achieved heat-treat evolution: material handling, energy source, and capital cost

Let’s talk about evolution. I don’t mean Darwin’s escapades on the HMS Beagle, but the evolution that has influenced the development of the OEM and heat treating industry, primarily carburizing and quenching. In July’s column, I presented operating cost, not capital investment, but utility usage for the batch vacuum process LPC/HPGQ, batch gas nitriding and […]
