MATHEMATICAL MODELLING OF TEETH CONTACT IN PRECESSIONAL TRANSMISSION [PDF]

Journal of Engineering Science (Chişinău), 2019
The article deals with the development of the 2K-H precessional toothed gear with convex-concave contact of the teeth. The teeth flanks of the satellite are described in the circular arc, and the central wheels - with convex / concave profiles.

Chiral Star-Shaped [Co^III₃Ln^III] Clusters with Enantiopure Schiff Bases: Synthesis, Structure, and Magnetism

Molecules
Two enantiomeric pairs of new 3d–4f heterometallic clusters have been synthesized from two enantiomer Schiff base derivatives: (R/S)-2-[(2-hydroxy-1-phenylethylimino)methyl] phenol (R-/S-H2L). The formulae of the series clusters are Co3Ln(R-L)6 (Ln = Dy (
