摘　　要：辐射治疗头是大型放射治疗设备的关键部件。基于内啮合齿轮副,设计了辐射治疗头圆弧提升运动机构。在设计中,分析了内啮合齿轮副的受力状态,并对齿根弯曲应力进行了理论计算及有限元分析。有限元分析结果与理论计算结果为同一数量级,偏差为1%,确认有限元分析结果可信。The radiation therapy head is a key component of large-scale radiation therapy equipment.The arc lifting mechanism for radiation therapy head was designed based on internal gear pair.In the design,the stressed state of the internal gear pair was analyzed,and the theoretical calculation and finite element analysis of the tooth root bending stress were carried out.The finite element analysis result is the same order of magnitude as the theoretical calculation results.Since the deviation is 1%,it is confirmed that the finite element analysis result is credible.
