Title: Noise lowering method for high speed rotary body
Inventor: TANAKA SATOSHI
IPC: B65H54/00
Filed: 1987-01-26
Abstract: PURPOSE:To suppress the vibration of air due to separation and lower noise by giving a rough form of dimples or knurling tool etc., to the surface of a high speed rotary body in a collecting device for linear bodies or a taping device, etc. CONSTITUTION:An air separating phenomenon which is the cause of sound generated from a high speed rotary body occurs in such a way that, as the velocity of a boundary layer which exists between an object and air increases, the pressure close to an object surface 20 is reduced causing a boundary layer separating phenomenon 21 in which the flow near the object surface 20 is sepa rated from the object surface, and a reverse flow 22 takes place to a larger extent toward a lower course, thereby, producing eddies to generate sound. Hence, a dimple type roughness 1 or a knurling tool type roughness 2 is formed on the object surface 20, thereby, eliminating the production of a boundary layer, to suppress the generation of a separating phenomenon. Thus, the vibra tion of air due to separation can be suppressed lowering noise.
