Abstract

本实用新型公开了一种内齿弹性垫圈。旨在提供一种弹性好、防松效果好的内齿弹性垫圈。它是环形的垫圈,其特征是在垫圈内孔的四周制有多个自垫圈中心放射形的切口,形成相互紧挨的内齿,内齿顶端相对垫圈平面逆时针扭转15-30度。该实用新型由于在垫圈的整个内圈都设有扭转的弹性齿,故该垫圈弹性好,防松效果好。

Description

内齿弹性垫圈
技术领域
本实用新型涉及一种紧固件,更具体地说涉及一种内齿弹性垫圈。
背景技术
现有的GB861.1-87内齿锁紧垫圈如同内齿轮,在向中心孔伸的各内齿顶端相对垫圈平面逆时针扭转15-30度。如图1、图2所示。这样的结构弹性差,对于在振动大的机械设备上使用容易松动。
发明内容
本实用新型的目的是提供一种弹性好、防松效果好的内齿弹性垫圈。
为了达到上述要求,所采用的技术方案是:它是环形的垫圈,其特征是在垫圈内孔的四周制有多个自垫圈中心放射形的切口,形成相互紧挨的内齿,内齿顶端相对垫圈平面逆时针扭转15-30度。
根据上述方案制造的内齿弹性垫圈,由于在垫圈的整个内圈都设有扭转的弹性齿,故该垫圈弹性好,防松效果好。
附图说明
图1是GB861.1-87内齿锁紧垫圈的主视图;
图2是图1的剖面图;
图3是内齿弹性垫圈的主视图;
图4是图3的剖面图。
其中:1、垫圈;2、切口;3、内齿。
具体实施方式
下面结合附图和具体实施例对本实用新型作进一步的描述。
图3、图4是内齿弹性垫圈的结构示意图。从图中看出,它是环形的垫圈1,在垫圈1内孔的四周制有多个自垫圈1中心放射形的切口2,形成相互紧挨的内齿3,内齿3顶端相对垫圈1平面逆时针扭转15-30度。
