Abstract

一种工字形整体密封圈,具有内圈和外圈,内圈 为一轴孔(3)内圈与外圈之间为翼缘(1),左右对称, 左右翼缘(1)之间沿圆周方向有凹槽,工字形密封圈 为整体结构,是纺织行业棉、化纤纯纺和混纺细纱机 的牵伸机构中的前后上罗拉轴承防止飞花的密封圈, 本实用新型密封性能可靠,设计先进,节约原材料,加 工制造简单,提高使用寿命和成纱质量。

Description

本实用新型是关于纺织行业细纱机特别是棉、化纤纯纺和混纺细纱机的牵伸机构中的前后上罗拉轴承密封圈的改进发明。
在现有技术中,棉、化纤纯纺和混纺细纱机的上罗拉轴承安装在摇架上,经摇架扣压后随下罗拉一起转动,形成一个握持钳口上罗拉轴承两端各有一个外壳,每个外壳都是独立运转的,每个罗拉轴承外壳有两排制作精良的轴承使上罗拉具有高度的导纱能力,进行纺纱牵伸,公知技术是在上罗拉轴上用六片不同规格的密封片进行层叠式迷宫密封结构,但是,由于这种叠片式迷宫密封结构复杂,性能不稳,易卡飞花,导致纺纱粗细不均,严重影响成纱质量。
鉴于公知技术存在的问题,本实用新型的目的旨在设计一种防止飞花卡入密封圈。加工制造简单,节约原材料、密封性能可靠的上罗拉轴承的密封装置。
本实用新型的机械结构(参见附图1、2)具有内圈和外圈,内圈为一轴孔(3),与上罗拉轴承轴压配,内圈与外圈之间为翼缘(1),翼缘(1)左右对称,左右翼缘(1)之间是一条沿圆周方向的凹槽(2),在加工时,外圈的中心线与内圆轴孔中心线必须在同一轴线上重叠。用本设计主题所制造的工字形整体密封圈压配在细纱机上罗拉轴承的芯轴上,就代替了传统的古老的叠片密封结构。
本实用新型与公知技术相比,由于改进了密封结构,飞花不易卡入罗拉轴承的密封圈内减少了维护保养的工作量,延长了使用寿命、提高了成纱质量,而且密封可靠,零件结构简单,加工及工艺装配性好,是纺织行业细纱机特别是棉,化纤纯纺和混纺细纱牵伸机构上罗拉轴理想的密封装置。
本实用新型有如下附图
图1为本实用新型的剖视图
图2为本实用新型的俯视图
附图表示了本实用新型的结构及实施例,先将原材料冲压成型,然后套在同心轴上压紧在磨床上研磨加工,使外圈的中心线与内圆的中心线完全重叠为止,最后将成品抛光防腐处理,整套工序即告完毕。
