Integrated Heat Treating
For decades the gear industry has faced the challenge of producing high performance components in a cost-effective manner. To meet quality specifications the components...
Bearing Solutions for High-Speed Gearbox Applications
With performance considerations driving gearbox design, pinion (high speed shaft) operating speeds have increased greatly in recent years, often exceeding generally accepted design limits....
Alternatives to Gear Grinding
Stringent NVH requirements, higher loads, and the trend toward miniaturization to save weight and space are forcing transmission gear designers to increasingly tighten the...
Refurbishing Wind Turbine Gears
Multi-megawatt wind turbine gearboxes operate under demanding environmental conditions including considerable variation in temperature, wind speed, and air quality. It is not uncommon for...
Reducing Gear Rattle
Work trucks are getting quieter, driving the need for axillary power to do the same. While gear noise, whine, and rattle are not new,...
Increasing Efficiency with Synchronized Systems
Every manufacturer is faced with the decision at some point: is it time to upgrade equipment and expand my capabilities? The real question, however,...
A Grinding Solution
A company approached Ontario Drive & Gear (ODG) concerning a problem they were experiencing with a gear set used in a new application. It...
The Case for Cold Rolling
Powdered metal, extruded, hobbed, rack rolled, or cold roll formed… which manufacturing method produces the best gears and splines? That largely depends on evaluation...
Better Bevel Gear Production
Gleason revolutionized bevel gear production in 1989 with the introduction of the first fully CNC controlled cutting machine, called the Phoenix® 250HC. In 2001...
Milling Tools for Bevel Gears
Curved bevel gears are one of the most complex components in mechanical engineering, and special machines and tools have therefore been required to make...
Clamping Large Turned Parts
Increased demand for large-size parts such as gears and turbine blades, mostly coming from the energy sector, requires machine shops to reinvestigate their clamping...
Essential Lubrication Aspects
Empirical studies prove that 70-85 percent of the expected life cycle costs of a machine are determined during its development stage. Synthetic lubricants constitute...
Expert Broaching Services
Machine tool rebuilders—or those who consider themselves to be machine tool rebuilders—are commonplace nowadays. Rebuilding everything from CNC lathes to machining centers to presses,...
Recommendations for Reverse Engineering
Reverse engineering is a necessary activity in the modern industrial world. Rather than mount a defense against those who label it “copying,” the author...
New Dimensions in Metrology
As components get smaller and more complex, and the demand for high precision rises, manufacturing companies are challenged to produce high-quality products in a...
Comparing AGMA and FEA Calculations
Current AGMA standards provide information about the calculations of loose gears and gearbox components, with recommendations primarily based on the “traditional” methods of mechanical...
