Description

洗衣机脱水轴止转水封
技术领域
本实用新型属于密封装置,尤其是涉及一种洗衣机脱水轴止转水封。
背景技术
现有的洗衣机脱水轴水封大多是双唇,即只有一个主唇和一个副唇的结构,密封性能不可靠,寿命短。中国专利号为200420039999.2,名称为洗衣机脱水轴水封的专利,其采用包括密封体,密封体上带有密封唇和防尘唇,密封唇背面凹槽内设置螺旋弹簧,密封体内嵌有骨架的结构形式,特征是密封唇与防尘唇间设置中间唇,防尘唇背面也设置凹槽,凹槽内设置螺旋弹簧,密封体外周面设置突起的外密封唇。这种结构的水封存在定位不便、使用寿命低等问题。
发明内容
本实用新型的目的在于解决上述水封中存在的问题,提供一种密封性能稳定可靠、定位准确、使用寿命长的洗衣机脱水轴止转水封。
本实用新型采用如下解决方案:一种洗衣机脱水轴止转水封,包括骨架、骨架支撑的密封体、密封唇和副唇,其特征在于骨架为梯形骨架,密封体内、外均设置主唇和两道副唇、密封体上均匀分布四个定位凸台。内主唇背面设置凹槽,在凹槽中安装螺旋弹簧。
本实用新型应用于洗衣机脱水轴部位,工作环境为:洗衣机脱水轴单向转速1100rpm,双向转速200rpm,回转720°,密封介质为洗涤液,温度0-90℃,压力9.8kpa以下。
本实用新型与现有技术相比具有:启动扭矩低、密封性能稳定可靠、定位准确、防止转动、使用寿命长、结构强度高等优点。
附图说明
图1为本实用新型的主视图。
图2为本实用新型的剖视图。
具体实施方式
如图所示,本实用新型包括密封体1、梯形骨架2,密封体1与梯形骨架2硫化成一体结构,增强了本实用新型的结构强度。密封体1内设置主唇5和副唇6,在主唇背面凹槽3中安装的螺旋弹簧4起到紧固作用,保证水封与脱水轴之间为过盈配合,提高密封性能。副唇6有效防止异物渗入,起到保护主唇5和洗衣机脱水轴的作用。密封体1外设置多道密封唇7,提高了本实用新型的外圈与洗衣机座孔之间的密封性能。通过密封体上均匀分布四个定位凸台8,在与洗衣机装配时准确定位,并且有效的防止密封体1转动,降低磨损,使本实用新型的使用寿命提高到可与洗衣机同寿命。
