fulcrum bearing

The simulation of axial distortion of four-fulcrum thrust ball bearing pack of turbodrill

涡轮钻具四支点推力球轴承组轴向变形的仿真

During a compressor testing, slipping and rub under light load caused the assistant fulcrum ball bearing cease to be in effect and get damaged.

在某型发动机压气机部件试验过程中，试验件的辅助支点滚珠轴承由于轻载打滑造成轴承失效，导致试验件辅助支点被损坏。

Research and calculate of fulcrum bearing reaction on high-speed rotor

高速转子支承反力的计算与研究

Since the adjustment of axial clearance of assembled turbodrill has great influence on its performance and service life, and the four-fulcrum thrust ball bearing pack has direct relation the axial clearance, a simulation of the axial distortion of the bearing is made by means of ANSYS software.

鉴于涡轮钻具装配时轴向间隙的调整对钻具性能和工作寿命有极大影响，而四支点推力球轴承组与轴向间隙有直接关系，为此选择求解精度较高的ANSYS软件对轴承组轴向变形进行仿真。

The result is meaningful to the improvement of the design of the four-fulcrum thrust ball bearing pack of turbodrill.

研究结果对轴承组的设计改进和涡轮钻具轴向间隙的调整有一定指导意义。
