Planetary Gear Box

Structure noise of marine gearbox seriously affects warship’s concealment, stability of transmission system and amenity of crew working environment. There are many ways to control structural vibration. To add damping in reduction gear box is an effective measurement to suppress box resonance. The key to design damping structure is to determine the parameters of the structure. In most instances, the structural parameters depend on experience and many experiments, which is lengthy and expensive. This paper made an analysis at design stage of reduction gear product by finite element method. This can determine the parameters of box structure, and reduce the input effectively. This method has important theoretical value and application prospect.

Fea Analysis

With the qualities of smooth operation, high efficiency and small size, the planetary gear box was widely used in transmission field. In this paper, a 2-stage planetary gear box was studied. CAXA and Pro/E were used for modeling. The FEA analysis results were obtained by ANSYS, both the contact stress and the bending stress of the gear tooth root. The results showed that with the continuous action of cyclic loads, the excessive contact stress is the direct reason of the failure. Then, the system reliability evaluation was made, which can provide guidance for engineering practice.
