Power planetary precessional transmission research regarding acoustical behaviour

Autor: Iu Malcoci, N Trifan, O Ciobanu, R Ciobanu

Publikováno v: IOP Conference Series: Materials Science and Engineering. 1235:012051

In planetary precessional reducers vibration can appear at bearings, gears, misaligned shafts, unbalanced rotors, couplings. Changes in dynamic process affects not only normal behaviours of mechanical systems but also acoustical behaviour. Regarding
