Abstract

本发明公开了一种高速转子失效的试验装置，其包括驱动机构和转子，所述试验装置还包括保护机构，所述保护机构包括中间轴和与所述中间轴配合的限位轴承，所述限位轴承用于对所述中间轴的轴向进行限位；所述中间轴的两端分别与所述转子和所述驱动机构连接，所述中间轴与所述驱动机构之间沿轴向设置有第一间隙。转子的轮盘破裂或者转子的叶片飞脱等转子失效后，可能产生较大的轴向冲击载荷，转子整体将沿轴向移动，冲击载荷将由中间轴和限位轴承承担，同时由于中间轴与驱动机构之间沿轴向设置有第一间隙，中间轴可以沿轴向小范围相对移动，避免中间轴直接对驱动机构产生轴向冲击，从而可以减小驱动机构受到的冲击载荷，减小设备损伤。
