Abstract

本实用新型公开了一种塑料泵叶轮防反转传动装置,包括相互螺纹连接的嵌件衬塑叶轮和轴,所述的嵌件衬塑叶轮的外径上和轴均设有一圈凹槽A,两凹槽A设有凸边式抱箍进行轴向限位,在所述凸边式抱箍的外径上设有凹槽B并装有弹性挡圈进行径向限位。本实用新型的有益效果是:利用对半剖分抱箍的凸边,卡入相互拧紧的轴和叶轮其外径上的凹槽A,进行轴与叶轮的轴向限位,剖分的抱箍则利用其外径的凹槽B上装的轴用弹性挡圈进行径向定位,防止抱箍的旋转分离。抱箍外径有斜面,挡圈的安装更加方便。抱箍是回转体剖分而成,故结构紧凑简单易于加工。

Description

塑料泵叶轮防反转传动装置
技术领域
本实用新型涉及一种防反转传动装置,更具体说,它涉及一种塑料泵叶轮防反转传动装置。
背景技术
螺纹传动的塑料泵叶轮,在泵设备反向起动或急停造成叶轮反转时,螺纹会松脱,必将导致叶轮向前运动并与壳体撞击造成损坏。
发明内容
本实用新型的目的是克服现有技术中的不足,提供一种结构紧凑、工作可靠、使用方便的塑料泵叶轮防反转传动装置。
本实用新型的目的是通过以下技术方案实现的:这种塑料泵叶轮防反转传动装置,包括相互螺纹连接的嵌件衬塑叶轮和轴,所述的嵌件衬塑叶轮的外径上和轴均设有一圈凹槽A,两凹槽A设有凸边式抱箍进行轴向限位,在所述凸边式抱箍的外径上设有凹槽B并装有弹性挡圈进行径向限位。
作为优选:所述凸边式抱箍外径设有配合挡圈安装的斜面。
作为优选:所述凸边式抱箍为回转体剖分而成的结构。
本实用新型的有益效果是:利用对半剖分抱箍的凸边,卡入相互拧紧的轴和叶轮其外径上的凹槽A,进行轴与叶轮的轴向限位,剖分的抱箍则利用其外径的凹槽B上装的轴用弹性挡圈进行径向定位,防止抱箍的旋转分离。抱箍外径有斜面,挡圈的安装更加方便。抱箍是回转体剖分而成,故结构紧凑简单易于加工。
附图说明
图1是本实用新型结构示意图;
附图标记说明:嵌件衬塑叶轮1、轴2、弹性挡圈3、凸边式抱箍4.
具体实施方式
下面结合附图和实施例对本实用新型做进一步描述。虽然本实用新型将结合较佳实施例进行描述,但应知道,并不表示本实用新型限制在所述实施例中。相反,本实用新型将涵盖可包含在有附后权利要求书限定的本实用新型的范围内的替换物、改进型和等同物。
如图1所示,这种塑料泵叶轮防反转传动装置,包括相互螺纹连接的嵌件衬塑叶轮1和轴2,所述的嵌件衬塑叶轮1的外径上和轴2均设有一圈凹槽A,两凹槽A设有凸边式抱箍4进行轴向限位,在所述凸边式抱箍4的外径上设有凹槽B并装有弹性挡圈3进行径向限位。所述凸边式抱箍4外径设有配合挡圈3安装的斜面。所述凸边式抱箍4为回转体剖分而成的结构。
