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 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 principle.On

The liner materials in coal fired tube mills are less promising due to lower combination of abrasion wear resistance, hardness and impact toughness properties, thus giving service life of 25,000 to 35,000 hours.In this study, focus was given to develop a high PH-PRO Cr-V cast iron of high abrasion wear resistance with higher hardness and impact str

Abstract Background Leishmaniasis is one of the most neglected tropical diseases in the world and remains endemic in some underdeveloped regions, including western China.The phylogeny and classification of Chinese Leishmania has not been completely clarified to date, especially within the Leishmania (L.) donovani complex, although phylogenetic anal

Diversity and pluriculturalism in current schools require educational strategies for prevention and intervention in the face of possible problems of school coexistence that may arise at different educational stages.This book is Massage Therapy focused on the issue of bullying, offering in its different chapters a diverse perspective of situations i

This paper summarizes the body of work that we have done over the years on the oscillation processes in sunspots, including their umbra, penumbra, and close vicinity.The Sinus Treatment study analyzes a number of aspects that impede adequate determining of some characteristics of propagating oscillations and lead to misinterpretation.Using running
