1 Gear Finishing by Shaving, Rolling and Honing, Part II (May/June 1992)

Part I of this series focused on gear shaving, while Part II focuses on gear finishing by rolling and honing.

2 The Next Step in Bevel Gear Metrology (January/February 1996)

In recent years, gear inspection requirements have changed considerably, but inspection methods have barely kept pace. The gap is especially noticeable in bevel gears, whose geometry has always made testing them a complicated, expensive and time-consuming process. Present roll test methods for determining flank form and quality of gear sets are hardly applicable to bevel gears at all, and the time, expense and sophistication required for coordinate measurement has limited its use to gear development, with only sampling occurring during production.

3 Gleason Cutter Head Improves Tool Life and Productivity (November/December 2009)

The Pentac Plus is the latest generation of Gleasonís Pentac bevel gear cutting system. It is designed to allow much higher tool life and improved productivity, especially for cutters using multiple face blade geometry.

4 Delivering Big Gears Fast (May 2013)

When a customer needed gears delivered in three weeks, hereís how Brevini Wind got it done.

5 Mechanical Behavior and Microstructure of Ausrolled Surfaces in Gear Steels (March/April 1995)

Ausforming, the plastic deformation of heat treatment steels in their metastable, austentic condition, was shown several decades ago to lead to quenched and tempered steels that were harder, tougher and more durable under fatigue-type loading than conventionally heat-treated steels. To circumvent the large forces required to ausform entire components such as gears, cams and bearings, the ausforming process imparts added mechanical strength and durability only to those contact surfaces that are critically loaded. The ausrolling process, as utilized for finishing the loaded surfaces of machine elements, imparts high quality surface texture and geometry control. The near-net-shape geometry and surface topography of the machine elements must be controlled to be compatible with the network dimensional finish and the rolling die design requirements (Ref. 1).

6 Determining Power Losses in the Helical Gear Mesh (September/October 2005)

This article reviews mathematical models for individual components associated with power losses, such as windage, churning, sliding and rolling friction losses.

7 Effects on Rolling Contact Fatigue Performance--Part II (March/April 2007)

This is part II of a two-part paper that presents the results of extensive test programs on the RCF strength of PM steels.

8 Effects on Rolling Contact Fatigue Performance (January/February 2007)

This article summarizes results of research programs on RCF strength of wrought steels and PM steels.

9 A Study on Reducing Gear Tooth Profile Error by Finish Roll Forming (July/August 2005)

The authors have developed a rack-type rolling process in which a rack tool is used to roll gear teeth. The results and analysis show that the proposed method reduces errors.

10 Gear Finishing by Shaving, Rolling and Honing, Part I (March/April 1992)

There are several methods available for improving the quality of spur and helical gears following the standard roughing operations of hobbing or shaping. Rotary gear shaving and roll-finishing are done in the green or soft state prior to heat treating.
