The present invention relates to a composite washer (100) for force indication and prevention of fastener loosening. The composite gasket includes a top portion (120) having a circumferential extension about an axis, an elastic portion (130) having a circumferential extension about the axis, a base portion (140) having a circumferential extension about the axis, where the top portion, the elastic portion and the base portion are connected to each other, where the elastic portion is arranged between the top portion and the base portion, and where the elastic portion is arranged between the top portion and the base portion. Wherein there is a central opening (102) having an extension along the axis through the top portion, the resilient portion and the base portion. Further, the composite gasket is arranged in a primary state in which the elastic portion is visible at the lateral surface of the composite gasket, and wherein the composite gasket is arranged in a secondary state in which the elastic portion is visible at the lateral surface of the composite gasket. The elastic portion is compressed by the top portion and the base portion such that the elastic portion is hidden by at least one of the top portion and the base portion at a lateral surface (104) of the composite gasket. Accordingly, a composite washer is provided that indicates a tightening force on a fastener and resists loosening of the fastener.
本发明涉及一种用于力指示并防止紧固件松动的复合垫圈(100)。复合垫圈包括具有围绕轴线的周向延伸部的顶部部分(120)、具有围绕该轴线的周向延伸部的弹性部分(130)、具有围绕该轴线的周向延伸部的基部部分(140),其中顶部部分、弹性部分和基部部分彼此连接,其中弹性部分被布置在顶部部分与基部部分之间,其中存在中心开口(102),该中心开口具有沿着该轴线贯穿顶部部分、弹性部分和基部部分的延伸部。进一步地,复合垫圈被布置成处于初级状态,在初级状态下,弹性部分在复合垫圈的侧向表面处是可见的,并且其中复合垫圈被布置成处于次级状态,在次级状态下,弹性部分被顶部部分和基部部分压缩成使得弹性部分在复合垫圈的侧向表面(104)处被顶部部分和基部部分中的至少一者隐藏。因此,提供了一种指示紧固件上的拧紧力并且抵制紧固件的松动的复合垫圈。
