1 Eddy Current Examination of Gear Systems (May/June 1997)
Nondestructive examination (NDE) of ferrous and nonferrous materials has long proved an effective maintenance and anomaly characterization tool for many industries. Recent research has expanded its applicability to include the inspection of large, open gear drives. Difficulties inherent in other NDE methods make them time-consuming and labor-intensive. They also present the user with the environmental problem of the disposal of used oil. The eddy current method addresses these problems.
2 Do No Destructive Testing (January/February 2013)
An overview of nondestructive testing and its importance in the manufacture of big gears.
3 Large Pinions for Open Gears - The Increase of Single Mesh Load (January/February 2013)
This paper introduces mandatory improvements in design, manufacturing and inspection - from material elaboration to final machining - with special focus on today's large and powerful gearing.
4 Grinding Induced Changes in Residual Stresses of Carburized Gears (March/April 2009)
This paper presents the results of a study performed to measure the change in residual stress that results from the finish grinding of carburized gears. Residual stresses were measured in five gears using the x-ray diffraction equipment in the Large Specimen Residual Stress Facility at Oak Ridge National Laboratory.
5 Flank Breakage on Gears for Energy Systems (November/December 2011)
Gear flank breakage can be observed on edge zone-hardened gears. It occurs, for example, on bevel gears for water turbines, on spur gears for wind energy converters and on single- and double-helical gears for other industrial applications.
6 In-Situ Measurement of Stresses in Carburized Gears via Neutron Diffraction (May 2009)
This paper presents the results of research directed at measuring the total stress in a pair of statically loaded and carburized spur gears. Measurements were made to examine the change in total stress as a function of externally applied load and depth below the surface.
7 Developing Flexible Couplings Standards (May 2011)
AGMA Flexible Couplings committee chairman Glenn C. Pokrandt gives an update about standards and other documents under development.
8 Gear Hobbing Technology Update (June/July 2011)
Q&A with Liebherr's Dr. Alois Mundt.
9 Microsecond Heat Treatment of Gears (March/April 2000)
The performance of metal surfaces can be dramatically enhanced by the thermal process of rapid surface melting and re-solidification (RMRS). When the surface of a metal part (for instance, a gear) is melted and re-solidified in less than one thousandth of a second, the resulting changes in the material can lead to: Increased wear and corrosion resistance, Improved surface finish and appearance, Enhanced surface uniformity and purity, and Sealing of surface cracks and pores.
