Reduction of the tonality of gear noise by application of topography scattering for ground bevel gears
The noise behavior of transmission is mainly caused by the excitation in the gear mesh. The standardized design and calculation […]
Hob quality basics
The quality of a hob directly affects the final quality of the gear it generates. AGMA has developed a standard […]
Tooling & Workholding: Improving tool holder performance
The four critical requirements for tool holders are clamping force, concentricity, rigidity, and balance for high-spindle speeds. When these factors […]
Long hob cost savings over the length of a job
Manufacturers consider many factors when shopping for a gear hob solution: What material is being cut? What is the pitch […]
Chamfer Hobbing Tools Up
In the last few years, chamfering and deburring have gained new respect and risen to a level of importance equal […]
Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing
Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear […]
Filling Some Gaps in Spline Design Guidelines: Centering, Friction, and Misalignment
Editor’s note: At the author’s request, some statements have been removed for clarity since the article was originally published in October, […]
Taking deburring to the next level
Once a gear is created, deburring becomes a necessary step to ensure a gear’s accuracy. Traditionally, deburring has been done […]
Tooling Workholding: A new solution for bevel gears
The creativity of the designers knows no bounds with new drive element and gear geometries. Faced with constantly increasing demands […]
Tooling & Workholding: A success story: Low-deformation workpiece clamping
Those who want to turn, mill, or grind rings, flanges, housings, or other thin-walled parts will quickly reach the limits […]
Chamfer Hobbing, Perfect Timing
New gearbox developments, particularly for eDrives, are creating a whole new set of gear design and manufacturing criteria. Compact gearbox […]
