The authors analyzed the fundamental principle of sound wave and the subjective evaluation of noise. According to the kinematics of machine tool, we analyzed the producing mechanism and main influence factors of machine tool firstly, then analyzed and measured the milling noise of internal gear milling machine tool, and get the main influence factors of gear noise were from meshing basic frequency...
As a new type of gear based on Bertrand conjugation theory, normal circular-arc bevel gear selects directrix on the basis of paying attention to machining planning process. When the directrix serves as loxodrome, the formed tooth profile surface not only has fine transmissibility like general arc bevel gear, but also is convenient to machining. The paper studies the forming principle of normal circular-arc...
