Root cause for noise excitation in geometrically-accurate (perfect) parallel-axes gearing

Theoretically, geometrically-accurate gearing that features zero base pitch variation promise to be noiseless, as no noise is produced by the gear mesh. In reality they can be noisy.

Gears are extensively used to transmit a rotation from a driving shaft to a driven shaft. Depending on the gear application, various configurations of the gear-shaft axes are distinguished. In the general case, gear-shaft axes cross one another; in one particular application, the gear shaft axes intersect one another; finally, in another particular application, the […]

Using simulation to evaluate part green shape to reduce distortion during plug quenching

The commercially available heat-treatment simulation software, DANTE, has been used successfully to improve heat-treat processes and steel-part characteristics; this case study follows an example of applying the software to evaluate a real-world challenge.

Determining the heat-treatment geometry (green shape) for complex gears is not a trivial task. Mass distribution becomes critical in determining the uniformity of heat removal, and subsequently, the uniformity of solid-state phase transformations. The uniformity of transformation directly affects the distortion after quenching. For decades, distortion control during heat treating has been based on experience. […]

Filling Some Gaps in Spline Design Guidelines: Centering, Friction, and Misalignment

This paper provides an accurate method for calculating radial loads transmitted by straight-sided splines by means of the effective pressure angle calculation, enabling more accurate hoop-stress calculation for these splines.

Editor’s note: At the author’s request, some statements have been removed for clarity since the article was originally published in October, 2019. International spline standards such as ISO 4156, ISO 14, ANSI B92.2, and SAE J499a have detailed definition of two-dimensional spline geometry but cover only the most basic axial effects such as helix error. Other […]

Quench system monitoring requirements in AMS 2759G

Determining the minimum hardness required by AMS 2759G requires attention to the specific hardenability curve of the specimen material and proper equipment maintenance.

AMS 2759G Heat Treatment of Steel Parts, General Requirements [1] was adopted April 23, 2019. This important aerospace specification governs the heat treatment of aerospace parts and incorporates a number of changes related to testing the quenchant and, most importantly, the quenching system. Previously, this specification only focused on the quenchant and did not look […]

Gear mesh and tooth modifications 

The involute gear form allows for a fluid mesh of the teeth as they slide along one another.

As we march through this thing that we all call life, we look to find our perfect partner — that singular person that perfectly meshes with our personality, improves our weaknesses, and complements our strengths. Sometimes we will make enhancements to our physical self in order to iron out some of our perceived surface flaws. […]
