The Root Cause for Gear Noise Excitation

Though focused primarily on parallel-axes gearings, the following methods are also valid for gear pairs with intersected axes of rotation, as well as crossed-axes
of rotation of the gears.

This article is about noise excitation and vibration generation in gear drives when the gear drives operate. It is shown that transmission error is not the root cause for the noise excitation as it is commonly meant. Instead, transmission error is a consequence of deviation of base pitches of a gear and a mating pinion […]

How Polyketone Polymers Improve Gear Performance

Superior wear properties, better dimensional control/stability, superior creep rupture performance, and quieter operation are a few of the benefits these polymers provide.

Engineers have been using thermoplastic resins to produce gears used in assemblies for the automotive, appliance, business equipment, and other market segments for many years. Thermoplastics offer several improvements over metals, including lower cost, less noise, and lighter weight, along with less energy loss due to frictional heat generation in non-lubricated gear sets. Historically, the […]

Psychoacoustic Methodology for the Noise Reduction of Bevel Gears

How Fast Fourier Transformations of single flank errors can be used during the development of a gearset to establish harmonic levels and side bands of quiet rolling gearsets.

The relationship between FFTs and gear quality as well as gear noise is investigated with some surprising conclusions, which leads to the discovery of a new interpretation of higher harmonics and the unknown influence of the residual error. An excursion into the psychoacoustic science in this phase of the research delivered many useful answers. Finally, […]

Continuous Cooling Transformation Diagrams

CCT diagrams allow predictions of hardness and microstructure in simple shapes quenched in oil, water, or other quenchants.

In the last column, we discussed the construction and application of Time Temperature Transformation or Isothermal Transformation diagrams. It was shown how these diagrams could be used to start planning a heat-treatment schedule, and start picking times and temperatures necessary to achieve the desired properties. However, one of the limitations of the diagrams is that […]

The key to a proper fit for keyways

Selecting the proper size keyway is determined by the shaft size. Sometimes you can put a square peg in a round hole.

Did you ever have someone tell you that you cannot fit a square peg into a round hole? This common phrase is misleading because it details the dimensions of neither the peg nor the hole. Clearly if the peg is 1-inch square and the hole is 4 inches in diameter, then the peg will easily […]
