Abstract

一种轴承密封用防尘盖，包括盖体，所述盖体的外圈一周上布置外凸点。本发明提供一种不容易脱落、可靠性良好的轴承密封用防尘盖。

Description

轴承密封用防尘盖
技术领域
本发明涉及轴承领域，尤其是一种轴承密封用防尘盖。
背景技术
目前防尘盖可分为可拆卸（活盖）及固定式（死盖）二种：活盖有变形小的优点及防尘槽复杂及安装困难的缺点，死盖有装配后变形大的缺点及装配简单和能自动化的优点，现有防尘盖存在的缺陷：容易脱落、可靠性较差。
发明内容
为了克服已有防尘盖的容易脱落、可靠性较差的不足，本发明提供一种不容易脱落、可靠性良好的轴承密封用防尘盖。
本发明解决其技术问题所采用的技术方案是：
一种轴承密封用防尘盖，包括盖体，所述盖体的外圈一周上布置外凸点。
优选的，所述一周上布置至少三个外凸点，所述至少三个外凸点等圆弧间隔设置。
进一步，所述外凸点的个数为奇数。
本发明的技术构思为：通过在防尘盖外圆上冲压出奇数凸点，靠外径和防尘槽的过盈量来固定，同时由于改变了死盖的冲压力，轴承的变形也得到了控制。
本发明的有益效果主要表现在：容易脱落、可靠性良好。
附图说明
图1是轴承密封用防尘盖的示意图。
图2是图1的截面图。
图3是轴承密封用防尘盖装配到轴承上的示意图。
具体实施方式
下面结合附图对本发明作进一步描述。
参照图1～图3，一种轴承密封用防尘盖，包括盖体1，所述盖体的外圈一周上布置外凸点2。
优选的，所述一周上布置至少三个外凸点，所述至少三个外凸点等圆弧间隔设置。例如三个、四个等；
进一步，所述外凸点的个数为奇数。
本实施例通过在防尘盖外圆上冲压出奇数凸点，靠外径和防尘槽的过盈量来固定，同时由于改变了死盖的冲压力，轴承的变形也得到了控制。

Claims (1)
