Morphology of FZG-A Test Gears

This study explores the failure mode morphology of FZG-A test gears. It aims to examine the orphologies of scuffing, scoring, scratches, and polishing using high-magnification light optical microscopy (LOM) and scanning electron microscopy (SEM) images.

Investigating the Effects of Wear, Lubrication and Material Pairing on the NVH Performance of Plastic Gears

This study systematically evaluates how material selection, progressive wear, and grease lubrication affect the noise, vibration, and harshness (NVH) performance of polymer gears, providing new insights for designing quieter, more optimized transmission systems.

A Review on Gear Transmission Error

This paper will review the development process, current research status, characteristics, functions, and measurement methods of TE. It will analyze the difficulties and core issues existing in the basic theory of TE, clarify the limitations and deficiencies of TE, and explore ways to overcome the shortcomings of TE.

The Intrinsic Pitch Cones in Hypoid Gears

A method to calculate pitch cones for hypoid gears using macrogeometry parameters—similar to non-offset bevel gears—while accounting for the added complexity of hypoid offset, tooling, and cutting technology is explored in this paper.

Design

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes

2023 is shaping up to be our planet’s hottest year on record, and the wind energy industry is feeling the heat. The GWEC (Global Wind Energy Council) says that the rate of wind turbine installations will need to quadruple globally by the end of the decade if we’re to achieve the IRENA’s (International Renewable Energy Agency) goal of net zero carbon emissions by 2050—and keep the average annual temperature worldwide from increasing more than the predicted 1.5° C. Fortunately, “net zero” commitments are gathering global momentum. Before year’s end, total global windpower is expected to reach a historic milestone of 1 TW of installed capacity, eliminating 1.2 billion tons of CO2 annually, roughly the equivalent of all the carbon emissions of South America.
