dynamic forces in meshing - Opis:
- Torsional vibrations occur during drive systems operation. They may be especially hazardous if the freQuency of input functions is close to resonance frequency or if system resonance frequency is equal to subharmonic of input function frequency. What 's more, there is always a possibility of more than one resonance zone since the system is usually non-linear and multi-body. In design process of power transmission systems very important is correctly selection of the couplings parameters (especially flexibility). Couplings stiffness and damping have principle influence on shaft torsional vibrations. In case of power transmission with tooth gear the vibrations which are connected with dynamic forces in meshing. The paper presents influence of flexible couplings stiffness characteristics on dynamic forces in meshing. The investigations based on the measured couplings stiffness as well as damping and computer simulation ofpower transmission system with tooth gear operates at varying load. On the basis of conducted tests and analysis it may be stated that toothed wheels rotational speed increase does not always result in meshing dynamic forces increase. dynamic model ofdrive system with toothed gear is therefore a useful toolfor analysing couplings impact on meshing dynamic forces. This is illustrated by examples presented in current paper.
