Název v původním jazyce

Dynamics of four-planetary gearing box

Popis výsledku v původním jazyce

Planetary gearboxes are more complicated than parallel-axis gear transmission systems andntherefore they need deeper dynamic analysis, which is important for reduction of noise and vibration. The main advantage of planetary gearings is the splitting of force flow into several planet wings, but it can be devaluated by unequal load sharing on planet stages. For improving, the floating sun wheal and flexible pins of planets are applied. Dynamic model of such a gearing box is derived in the paper and it is shown that the frequency spectrum contains many multiple eigen-frequencies. Examples of several eigen-modes and transfer functions of this four-planetary gearing box are presented as well. The problem of dimensional nonhomogeneous vectors and matrix is also mentioned.
