| 摘 要： | Dynamic investigations revealed that lower order harmonic resonance phenomenon exists in the threering gear transmission. That is, when the input speed is close to 1/3, 1/6, 1/9,-“, 1/3n of the primary natural frequency of the transmission, the loads on the bearings and gears are especially high. This paper explained thisphenomenon from the viewpoint of parametric resonance in terms of perturbation technique. A conclusion was drawn that the basic reason for this phenomenon is the primary resonance caused by forcing excitation and para-metric resonance caused by parametric change. |
