批量生产的链轮密封轴面的扭纹检测评定

Twist Measurement of Sealing Surface on Sprocket Parts in Mass Production

针对发动机正时链轮旋转密封问题,分析了密封面关键因子扭纹的成因。通过介绍扭纹测量方法,详细描述了悬重棉线偏移法及其测量原理。最后在零件大批量生产质量监控过程中,应用了该悬重棉线偏移测量法,保证质量目标证明了方法的实用性。

Based on leakage issue of sprocket part with shaft sealing surface, the root cause and twist texture generation is introduced. Methods of suspended weight/ thread is described in detail, including device setting and measurement principle. Measurements are introduced and validated in part mass production application.
