EFFECTS OF TOOTH MODIFICATION IN THE INVOLUTE HELICAL GEAR FORM-GRINDING PROCESS ON LOADED TRANSMISSION CHARACTER WITH CONSIDERATION OF TOOTH AXIAL INCLINATION ERROR

Due to the existence of machining and installation errors, axis parallelism error of gear pairs chiggate.com occurs, which causes eccentric load and mesh in-out impact, thus weakening loaded transmission character.To solve this problem, the axis parallelism error of gear pairs was equated with tooth axial inclination error based on the gear-meshing

This article aims to analyze the concepts and relationships bolia outlet gent of the Triple Helix Model (THM) proposed by Etzkowitz & Leydesdorff as applied to international security and defense and the contribution of THM to the development of knowledge-based economies.The method used was a qualitative, descriptive analysis, reviewing reliable sci

Abstract Background Epidemiologic estimates are now available for a variety of parameters related to major depression epidemiology (incidence, prevalence, etc.).These estimates are potentially useful for policy and planning purposes, but it is first necessary that they be synthesized into a coherent picture of the epidemiology of the condition.Seve

Growing international and national focus on quantitatively measuring and improving ocean health has increased the need for comprehensive, scientific, and repeated indicators to track progress towards achieving policy and societal goals.The Ocean Health Index (OHI) is one of the few indicators available for this purpose.Here we present results from

Isolated right ventricle (RV) hypertrophy, anomalous muscle bundles, heavy trabeculations, a redundant hypertrophic papillary muscle, and variations in the shape and thickness of the moderator band (MB), with or without RV hypertrophy, may be confused with a cardiac mass on echocardiography.Therefore, multiple off-axis echocardiographic images and
