The operation of working machines is accompanied by the constant occurrence of vibrations and shocks, generated by various constructive, kinematic and dynamic factors. The study of the vibro-acoustic aspect of mechanical transmissions and, in particu

In this study, we propose a new toothed gear for mechanical transmissions built from a satellite wheel with two toothed conical crowns, one of which conjugates with a fixed central conical wheel mounted in the transmission housing and the other with

This paper deals with the theoretical-experimental model of the tribological behavior of the contact elements in precessional gears (PG) in the functions of conjugate profiles of linear velocities "convex-concave" or "convex-convex" for the correspon

The paper deals with the development of precessional gears with toothed gearing with concave-concave contact of inclined teeth. In order to increase the bearing capacity and the mechanical efficiency of the precessional gear, the contact of the teeth

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. The a

The planetary precessional transmissions represent a new principled type of the mechanical transmission. Precessional planetary transmission has a number of advantages: increased bearing capacity, high mechanical efficiency, large kinematical possibi

Claims of paleodata periodicity are many and controversial, so that, for example, superimposing Phanerozoic (0–541 My) mass-extinction periods renders life on Earth impossible. This period hunt coincided with the modernization of geochronology, whi
