Description

自加压弹性垫圈
技术领域
本实用新型属于电力***紧固件技术，特别涉及强电***的紧固件弹性垫圈，具体说是一种自加压弹性垫圈。
技术背景
电力***紧固件中使用65Mn、60Si2MnA弹簧垫圈，在正常状态下可有效防止被紧固件的松动。现在的电力***紧固件中的65Mn、60Si2MnA弹簧垫圈，虽然在正常状态下能有效防止被紧固件的松动，但是这种材料经常处在较高温度下（电流冲击造成发热或因震动造成紧固件松动导致的发热）会失去弹性，从而失去了防止被紧固件松动的作用。被紧固件松动后，因接触不良造成接触电阻增大而更加容易发热，烧损紧固件以及被紧固件，进而造成故障性停电，目前，供电企业每年因此而造成的停电故障经常发生，为了防止此类故障，不得不花费大量人力、物力定期更换所有的紧固件，造成的经济损失以及社会损失相当惊人。
实用新型内容
本实用新型所要解决的技术问题是目前在电力***使用的65Mn、60Si2MnA弹簧垫圈，在偶尔发生瞬间大电流或因雷击造成的大电流冲击时，紧固件不会随温度的升高失去弹性而使被紧固件松动，紧固失效的问题，从而提供一种在紧固件发热时弹性会加大，能防止被紧固件松动的一种自加压弹性垫圈。
本实用新型的技术问题采用下述技术方案解决：
一种自加压弹性垫圈，垫圈本体为环状，所述垫圈本体以中轴线对称呈“V”形对折状,对折边为加压部位，张开边为支撑部位。
所述垫圈本体的“V”形圆弧角度a为140°～160°，圆弧半径R为10～30mm。
所述垫圈本体采用记忆合金材料制成。
本实用新型采用记忆合金材料制成，利用记忆合金的特性——记忆性能以及超弹性，依靠自身的超弹性特性，不但具备普通65Mn、60Si2MnA弹簧垫圈的功能，更重要的是其在电力***偶尔发生的瞬间大电流或因雷击造成的大电流冲击时，紧固件会发热，随着温度升高，弹性就会加大，不会因温度的有限升高失去弹性而使被紧固件松动，紧固失效，可避免因被紧固件松动而造成的障性停电，节省了为定期更换所有的紧固件所需的大量人力、物力，可挽回经济损失以及社会损失，具有很好的经济和社会效益。
附图说明
 图1为本实用新型结构示意图；
 图2为“V”形对折状弧度示意图；
图3为本实用新型使用状态示意图。
具体实施方式
本实用新型是一种自加压弹性垫圈，采用记忆合金材料制成的垫圈本体1设计成以中轴线对称呈“V”形对折状的结构，对折边为加压部位3，张开边为支撑部位2。“V”形圆弧角度为140°～160°，圆弧半径R为10～30 mm。本实用新型由单一的记忆合金板材平面切割后，经过加热成型为“V”形，然后经过热处理工艺，800℃淬火，500℃回火，温度处理到60℃以上，使其具有记忆性能和超弹性，在常温或者低温下安装在紧固件上，依靠螺母将变形部分压平，依靠超弹性或受热后的记忆恢复力，通过加压部位3的记忆恢复实施加压，支撑部位2撑开，使被紧固件可靠连接而不松动。
