Reduction of gear pair transmission error with tooth profile modification [PDF]

open access: yes, 2008
The gear noise problem that widely occurs in power transmission systems is typically characterised by one or more high amplitude acoustic signals. The noise originates from the vibration of the gear pair system caused by transmission error excitation ...

Research on evaluation of tooth profile modification effect of locomotive traction

open access: yesJournal of Physics: Conference Series
Abstract At present, the evaluation of the tooth profile modification effect of locomotive traction gears is plagued by the drawbacks of a single evaluation index and a lack of systematic evaluation methods. In this paper, taking a specific type of locomotive traction gear as the research object, we adopt the tip modification scheme ...

TRAF6 Lactylation in Glycolytic Macrophages Drives NF-κB Signaling and M1 Polarization During Orthodontic Tooth Movement. [PDF]

open access: yesAdv Sci (Weinh)
Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone
