Description

汽车发动机气门弹簧
技术领域
 本实用新型涉及一种弹簧，尤其涉及一种汽车发动机气门弹簧。
背景技术
随着对发动机性能要求的不断提高和市场竞争的不断加强,发动机气门弹簧是汽车发动机的重要零部件，是国产化中的甲类件。该弹簧属圆柱压缩螺旋弹簧，圆柱压缩螺旋弹簧在轴向力的作用下，弹簧的任意横截面所受的切应力在弹簧内径受力最大，外径受力最小，容易导致弹簧内侧出现裂痕。
发明内容
本实用新型的目的在于提供了一种汽车发动机气门弹簧，该气门弹簧通过结构上的变化来提高弹簧使用寿命。
本实用新型是这样来实现的，它包括弹簧,其特征是弹簧长度为46-48mm，弹簧的外径为36-40mm，弹簧两端端面各磨平0.75圈，弹簧的线径为3.5-4.5mm，总圈数为5.5圈，有效圈数3.5圈，弹簧最小节距为2.5-3.5mm，最大节距为11-12mm。
本实用新型的技术效果是：在疲劳寿命热压缩性能、抗永久变形等方面具有良好的性能。
附图说明
图1为本实用新型的结构示意图。
在图中，1、弹簧。
具体实施方式
如图1所示，本实用新型是这样实现的，弹簧1长度为46-48mm，弹簧1的外径为36-40mm，弹簧1两端端面各磨平0.75圈，弹簧1的线径为3.5-4.5mm，总圈数为5.5圈，有效圈数3.5圈，弹簧1最小节距为2.5-3.5mm，最大节距为11-12mm。
