摘　　要：分析了现有市场上旋挖钻机动力头普遍采用的密封结构,针对其经常出现渗漏油问题提出了一种新的密封结构:动力箱下端采用的旋转密封方式换成静密封方式,并对动力头的其它结构作了相应调整。利用Pro/E和ANSYS Workbench软件建立了动力头模型,并对改进后的密封结构进行了初步的模态仿真分析,验证了其可行性。Analysis of the existing market on the rotary drilling rig power head is generally used to seal structure, this paper proposes a new seal structure in view of oil leakage constantly problem: power box bottom using static seal mode instead of rotating seal mode, and the power head of other structures corresponding adjustment. Use Pro/E and ANSYS Workbench established model of power head , and analysis the improvement of sealing structure after the preliminary mo Thai simulation , to validate its feasibility.
