Abstract

一种垫圈,其特点为在垫圈本体的内沿有1—3 个弹起,集平垫圈和弹簧垫圈为一体,在安装使用中 很方便,可以单个或多个叠摞使用,其生产成本低。

Description

本实用新型属于垫圈结构的改进。
在有振动的机械及设备上多采用双垫圈(即平垫圈和弹簧垫圈)来减少由于振动而引起的螺母松动,双垫圈的配合使用给安装过程就带来一些麻烦,尤其是装配空间较小时,操作更为不便;并且在其两种垫圈的生产上为两套生产工序,不仅浪费材料,而且费工费时,成本高。
本实用新型的目的在于设计一种集平垫圈和弹簧垫圈为一体的垫圈,以解决上述存在问题。
附图1为所设计垫圈结构的正视图,附图2为侧视图,图中1为垫圈本体,2为缓冲眼,3为弹起。
本实用新型的特征为:在垫圈本体(类似平垫圈结构)的内沿有弹起结构,即在本体上有一开缝,开缝的一端与内沿相通,开缝后所形成的条状体头高尾低的翘起,形成弹起;其开缝的另一端为缓冲眼,以增加弹起的力度,防止弹起的断裂,起缓冲作用;弹起的宽度从头到尾可以是渐宽的,也可以是等宽的,但最宽处不超过本体的宽度;从本体的中心到最宽处一般不超过其配合使用螺母的半径;弹起的长度在本体园周45°-360°之间选择;在一个本体上可有1-3个弹起;若有2-3个弹起,其弹起的方向一致,且分布均匀。
可以看出,本实用新型所设计的垫圈是集平垫圈和弹簧垫圈为一体,在安装使用中很方便,也可以多个叠摞使用,并能用于止推垫。其生产一套工序就可完成,节约材料,省工省时,降低了生产成本。所设计的垫圈可选用弹性钢材一次冲压而成。

Claims (3)
