摘　　要：针对尼龙隔离块注塑成型过程中出现的气泡、疏松等组织缺陷和合模线强度不足缺陷难以检测的问题,提出了一种通过检测隔离块的轴向及径向强度,间接检测隔离块的组织缺陷及合模线强度不足缺陷的方法。经实际应用证明此方法可以保证隔离块质量,满足风电转盘轴承的性能要求。It is difficult to detect microstructure defects such as bubble,porosity and so on and insufficient strength of clamping line during injection molding process of nylon spacer.A method is proposed for detection of microstructure defects of spacer and insufficient strength of clamping line indirectly by detecting axial and radial strength of spacer.After practical application,the method ensures that the quality of spacer meets performance requirements of slewing bearings in wind turbines.
