Abstract

本实用新型涉及一种定位用紧固螺帽,特别是一种能够对轴承进行轴向定位的紧固螺帽。螺帽一端带有内螺纹,另一端设有圆环形凸台。使用时,将圆环形凸台压紧轴承内圈,并将带螺纹的一端与带外螺纹的销轴拧紧可实现对轴承的轴向定位。

Description

一种定位用紧固螺帽
技术领域
本实用新型涉及一种定位用紧固螺帽,特别是一种能够对轴承进行轴向定位的紧固螺帽。
背景技术
轴承是机械结构中常用的零件,使用时需要对其进行轴向定位,通常使用套筒、弹性挡圈等与普通螺母组合进行紧固以实现轴向定位,零件数目较多。
实用新型内容
本实用新型提供了一种能够对轴承进行轴向定位的一种定位用紧固螺帽。
技术方案如下:一种定位用紧固螺帽,螺帽的一端带有内螺纹,另一端设有圆环形凸台,圆环形凸台的圆孔的内径比内螺纹的直径大。
本实用新型有益效果是:可以有效对轴承进行轴向定位,并可以减少结构的零件数目。
附图说明
图1是本实用新型定位用紧固螺帽的结构示意图;
图2是本实用新型定位用紧固螺帽的剖视图;
其中,1-圆环形凸台,2-内螺纹。
具体实施方式
下面通过具体实施方式对本实用新型作进一步说明:
请参阅图1和图2,本实用新型的结构示意图和剖视图。本实用新型定位用紧固螺帽,其一端带有内螺纹2,另一端设有圆环形凸台1。
使用时,通过紧固螺帽的内螺纹2与销轴的外螺纹联接并拧紧,使紧固螺帽的圆环形凸台1压紧轴承内圈,可实现对轴承的轴向定位。
综上所述,本实用新型定位用紧固螺帽结构简单,能可靠地对轴承进行轴向定位,并且可以减少结构的零件数目,具有较大的使用价值。
