摘要：为解决CMT1801型粗纱机罗拉颤顿问题，通过对问题纱进行乌斯特单纱实验及换粗纱对机械波波谱分析，并检查运转设备专用基础件，确定原因在于牵伸部位中罗拉装配问题。针对下胶圈清洁、老化及直径过小等质量问题和下销、拉滑座齿轮啮合与工艺配置问题，制定措施并试验观察效果。指出：罗拉震颤是下胶圈和下销棒配合过紧所致；采取缩短中罗拉滑座、下销后移，罗拉颤顿问题得到解决，条干疵布改善效果明显。

Abstract:In order to solve the problem of the quivering mid-roller with the roving frame CMT1801,single Uster test is done to the problematic yarn with analysis of mechanical wave spectrums and check-up is done to the operating equipments.The problem of the quivering mid-roller with the roving frame CMT1801 results from the improper assembly of the mid-roller in the draft section.Measures are taken for the solutions of cleaning,aging,excess small diameter of the bottom aprons,process configuration of the bottom cradle,gearing of the sliding socket and the consequent effects observed.It proves that the problem of the quivering mid-roller with the roving frame CMT1801 results from excess tight fit of the bottom apron and the bottom cradle.Shortening of the sliding socket of the mid-roller and back motion of the bottom cradle finds the solution to the problem of the quivering midroller,consequently marked improvement of the cloth with defected eveness.
Key Words:roving frame；mid-roller；quivering；apron；Uster evenness；defected cloth
