口腔CT传动精度要求高,多使用运行平稳、精度效率及安全系数高的谐波减速器,其柔轮转动时因承受交变载荷产生周期变形容易失效。对柔轮齿廓进行设计,运用SolidWorks进行建模,导入Ansys Workbench中进行了静力学分析、模态分析、瞬态动力学分析。结果表明,柔轮应变主要位于波发生器的长短轴处,且沿筒体轴向应变逐渐减小;应力最大值位于波发生器与柔轮接触位置,瞬态动力学分析时最大应力位于齿根与筒体连接处;同时,柔轮应力应变的大小还受齿宽、筒长、筒厚等影响。
The cone-beam oral CT requires high transmission accuracy
and harmonic reducers with smooth operation
high precision efficiency and safety factor are mostly used. Its flexspline is prone to failure due to periodic deformation under alternating load when rotating. The tooth profile of the flexspline is designed
modeled by SolidWorks
and imported into the Ansys Workbench for the static analysis
modal analysis
and transient dynamic analysis. The results show that the flexural strain is mainly located at the long and short axes of the wave generator
and the axial strain decreases gradually along the cylinder. The maximum stress is located at the contact between the wave generator and the flexspline
and the maximum stress is located at the connection between the tooth root and the cylinder during the transient dynamic analysis. At the same time
the stress and strain of the flexspline are also affected by tooth width
barrel length and barrel thickness.
