Distinctive behaviors of mesh force and transmission error in mesh stiffness model of spur planetary gear system considering elastic ring gear

open access: yesAdvances in Mechanical Engineering, 2022
In a planetary gear set with an elastic ring gear, there are several pairs of flexible internal meshing simultaneously. The interactions between them are often ignored when considering their mesh stiffness.

Thermo-hydro-dynamic investigation of journal bearing by a two dimensional model [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
Journal bearings are widely used in industrial machinery, working under heavy loading and high rotating velocity. These bearings are interfered sometimes with sever thermal damages. So the prediction of their exact working temperature is necessary.

Chemical and isotopic analyses of hydrocarbon-bearing fluid inclusions in olivine-rich rocks

open access: yesPhilosophical Transactions of the Royal Society A, 2020
We examined the mineralogical, chemical and isotopic compositions of secondary fluid inclusions in olivine-rich rocks from two active serpentinization systems: the Von Damm hydrothermal field (Mid-Cayman Rise) and the Zambales ophiolite (Philippines ...

Experiments on Cu-isotope fractionation between chlorine-bearing fluid and silicate magma: implications for fluid exsolution and porphyry Cu deposits

open access: yesNational Science Review, 2020
Hydrothermal fluid is essential for transporting metals in the crust and mantle. To explore the potential of Cu isotopes as a tracer of hydrothermal-fluid activity, Cu-isotope fractionation factors between Cl-bearing aqueous fluids and silicate magmas ...

Thrust bearing with fluid pivot

open access: yesJournal of Physics: Conference Series, 2021
Abstract This article describes the conditions arising from the operation of compressor and pumping equipment using traditional thrust bearings with mechanical support and leveling linkage system, which negatively affect the operation of dynamic machines in general and the thrust bearing in particular.
