Main shaft of numerical control machine tool is in machine tool of a lot of numerical control, because the gearshift system of main shaft still uses a certain number of transmission shaft, gear and bearing, because this is in the job,inevitable ground should produce oscillatory noise, attrition noise and concussion noise. And numerical control machine tool advocate the gearshift of transmission system is to be below the status that the machine tool does not suspend to work, by the computer control finishs, the noise that accordingly it produces than general accuracy machine tool is more successive, have more representative. Mechanical system gets the outside any stimulate brace up force, because be stimulated to this,the system is met brace up power generation is answered and appear oscillatory. This oscillatory energy travels in whole system, should transmit radiometer face, this energy becomes pressure wave with respect to changeover, classics air comes out again, namely acoustical radiate. Accordingly, arouse answer, systematic interior delivers the radiate that reach sound these 3 measure are oscillatory noise, attrition noise and concussion noise fashion a process. (1) of numerical control machine tool advocate transmission system basically is to rely on what gear will complete gearshift and drive accordingly, the drive of clench the teeth of gear is one of main noise sources. (2) the assembly of bearing and journal and bearing aperture, tighten beforehand force, homocentric degree, lubricant condition and action wait to have very big effect to noise in the size of the bear on bearing, bottom clearance. And the production deviation of bearing itself, decided the noise of bearing greatly. CNC Milling CNC Machining
