Parameter study on the calculated risk of tooth flank fracture of case hardened gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Due to better material qualities, new surface finishing methods and better heat-treatment process reliability, flank surface damages, such as pitting or micropitting, can be prevented in a reliable manner.

Bulletin of JSME, 1985 Gears made of four kinds of low-alloyed steels with different hardenabilities were through-hardened in a cooling oil to investigate an influence of hardenability on gear distortions which is considered as a criterion for thickness of hardened layer. From the experiment, the gear distortions caused by the hardening are found to be related not only with ...

Journal of Applied Polymer Science, Volume 143, Issue 10, March 10, 2026.Schematic overview of the upcycling of industrial LDPE waste via fused deposition modeling (FDM). ABSTRACT This study explores the potential of additive manufacturing (AM) to upcycle industrial waste low‐density polyethylene (LDPE) by investigating the effect of LDPE waste's melt flow index (MFI) on the printability of LDPE/polystyrene (PS) blends via ...

Layer Approach to Model Fatigue Strength of Surface-Hardened Components
MetalsThis paper deals with a surface-hardened forged steel that is commonly used for powertrain components like gears, axles or crankshafts. In order to increase static and fatigue strength and to minimise wear, surface treatments like induction hardening ...

Plastic deformation mechanism of hypoid gears
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Hypoid gears are used as the final reduction gear of vehicles to transmit and change direction torque. Plastic deformation of a hypoid gear tooth flank occurs when a load exceeding the yield stress acts on the tooth surface.

Bearing and gear steels for aerospace applications [PDF]
Research in metallurgy and processing for bearing and gear steels has resulted in improvements in rolling-element bearing and gear life for aerospace application by a factor of approximately 200 over that obtained in the early 1940's.

Advanced Science, Volume 13, Issue 14, 9 March 2026.A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...
