A Field Case Study of ‘Whining’ Gear Noise in Diesel Engines
This paper describes the work performed to reduce first order gear mesh vibration, which was the root cause of an excessive gear “whine.” It...
Casting, Forming, and Forging
There are many methods for manufacturing gears, including:
Metal removal processes (hobbing, shaping, milling, shaving, grinding, honing, and lapping)
Various casting processes for both...
Development of Novel CBN Grade for Electroplated Finish Grinding of Hardened Steel Gears
The grinding processes used in finish grinding of hardened gears can be classified as generating grinding and profile grinding, depending on how the profiles...
Workholding: A Vital Component of Gear Manufacturing
Never assume gripping a gear is easy. Gear workholding is possibly the most complex workholding challenge we face because of the complexities of the...
Contemporary Gear Pre-Machining Solutions
Depending on annual production volumes, batch sizes, and workpiece geometry, several gear manufacturing technologies are used for industrial gear production. The one most applied...
The Best of Both Worlds in Gear Manufacturing: High Flexibility with High Productivity
Sophisticated yet simple, providing full flexibility combined with high productivity, InvoMilling is the latest development when both efficiency and production versatility are needed for...
Gear Lubrication-Gear Protection Also At Low Oil Temperature
In practice, industrial gears are often operated with lower oil temperatures than would normally be generated in a fully-loaded gearbox. Lower temperatures prevail, for...
Precision Broaching of Gears Large and Small
The broaching of precision gears will always start with a designed broach to match the specification of the part print. The broach designer will...
The Effect of the Surface Roughness Profile on Micropitting
A wide choice of surface roughness parameters is available to characterize components such as gears or bearings, with the goal of predicting the performance...
Form and Position Measurement Advancement Through Measurement Technology
This industry has a tailwind; the wind power industry is growing at a rapid pace. The reasons for this are many. Ambitious climate targets,...
Crack Testing and Heat Treat Verification of Gears Using Eddy Current Technology
While eddy current technology was initially developed for testing of bar, tube, and wire, advances in electronics, automation, and coil design have paved the...
Two Case Studies in the Mining Industry with the KISSsoft Gearbox Variant Generator
When designing gears, the size, weight, and manufacturing cost can be influenced to a great extent by both strategically splitting the overall reduction over...
How to Minimize Downtime, Repair Costs, and Inventories by Extending the Life Expectancy...
Just like typical cars, gearboxes have gotten smaller over time. The catch phrase is ‘power-dense’, meaning that from equal sized gearboxes, the newer model...
Saving Time and Cost for Intricate Gear Peening
Shot peening is a cold working process used to produce a compressive residual stress layer and modify mechanical properties of metal by impacting a...
Analysis of Ripple on Noisy Gears
A low noise level is an important quality feature in modern gearboxes for passenger cars. But a troublesome noise can have many causes. The...
Comparative Corrosion Characteristics of Ground and Superfinished Gear Steels
The described effort was undertaken to assess the impact of the isotropic superfinishing (ISF®) process on the corrosion resistance of a variety of gear...
Horror Stories of Costing
My pet peeve is seeing companies lose money needlessly in the process of costing and pricing. This happens for four reasons:
1) They don’t have...
The Real Truth Behind Cpk and Ppk Capability and Potential Process Studies
The most common definition of Cpk and Ppk is this: Cpk is the short-term capability of a process, and Ppk is the long-term. The...
Exploiting the Potential of Plastic Gears
Plastic gears afford appliance designers dramatic opportunities to reduce drive cost, noise, and weight. However, due to the properties of engineering resins, plastic gears...
