SP-I-01型全液压顶驱齿轮副振动分析

Gear Pair Vibration Analysis of the SP-I-01 Hydraulic Top Drive Drilling System

摘要:

振动会对齿轮副正常稳定工作产生影响。齿轮副的设计过程中要使其固有频率避开工作频率。通过对SP-I-01型全液压顶驱传动齿轮副进行振动分析，得出了齿轮副前六阶的固有频率及对应的振型图,并计算出其最高工作频率，与其固有频率进行对比，得出了其最高工作频率低于其最低阶的固有频率，符合设计要求。

Abstract:

Vibrations influence normal and stable work of gear pair. In gear pair design process, inherent frequencies of gear pair should avoid working frequencies. Vibration analysis is made on the gear pair of SP-I-01 hydraulic top drive drilling system, the first 6 order inherent frequencies and the corresponding mode shape graphs of the gear pair have been obtained. The maximum operating frequency is calculated and by comparing with the inherent frequencies of the gear pair, the result is that the maximum operating frequency is lower than the inherent frequency of the lowest order, which meets the design requirements.
