摘　　要：利用叶栅进口及出口速度三角形探讨了对旋轴流式通风机二级风机轴承较一级风机轴承易损的原因,并经实验和流场数值模拟得到证实,据此提出了解决的方案。According to the inlet and outlet velocity triangle of cascade, the paper approaches the reason that the bearing of two-grade fan for contra-rotating axial fan is more vulnerable than one-grade fan. The conclusion is supported by the experiment and the numerical simulation of fluid field and its solution is put forward form this.
