Abstract
Description
本発明は、ナットの緩みを防止するワッシャである。The present invention is a washer that prevents loosening of a nut.
従来はスプリングワッシャ等でナットの緩みを防止していた。Conventionally, the nut was prevented from loosening with a spring washer or the like.
スプリングワッシャ等では振動でナットが緩んでいた。In the spring washer etc., the nut was loosened by vibration.
私が以前発明した、出願番号 特願２００３−４３６３３５では、ワッシャ硬度が高いと、ナット底部が削れてしまい、ワッシャ硬度が低いと、ワッシャの凸部が削り取られる為、緩み止め効果が得られなかった。In the application number Japanese Patent Application No. 2003-436335 that I invented before, if the washer hardness is high, the bottom of the nut will be scraped, and if the washer hardness is low, the convex part of the washer will be scraped off, so the loosening prevention effect cannot be obtained. It was.
本発明は、前記課題の解決手段として、ナットとナットの間に、切り起こし部分を形成した弾力性のあるワッシャを挟む事により、ナットの側面に突っ張り効果を与え、ナットの緩みを防止する。According to the present invention, as a means for solving the above-mentioned problems, a resilient washer having a cut-and-raised portion is sandwiched between the nuts, thereby giving a tension effect to the side surface of the nut and preventing the nut from loosening.
このワッシャを使用することにより、ナットをボルトのどの位置でも固定する事が出来る。By using this washer, the nut can be fixed at any position of the bolt.
以下、本発明の実施の形態について添付図面で説明する。
図２、で示すようにワッシャの切り起こし部分がナットの側面に突っ張り効果を与える事によりナットの緩みを防止する。Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 2, the cut-and-raised portion of the washer exerts a stretching effect on the side surface of the nut, thereby preventing the nut from loosening.
ワッシャの切り起こし個数はいくつでもよく図面に描いた個数にこだわるものではない、又、ワッシャの切り起こし形状もナットに緩み止め効果が得られれば、どのような形状でもよい。The number of washers raised and raised is not limited to the number shown in the drawing, and the shape of the washers raised and raised may be any shape as long as the nut can be prevented from loosening.
ワッシャを溶接等で固定できる場合は切り起こし部分は片面だけでよい。If the washer can be fixed by welding or the like, the cut-and-raised part need only be one side.
逆ネジの場合、切り起こし方向は図面と逆になる。In the case of a reverse screw, the direction of cutting and raising is opposite to the drawing.
要するに、ナットを締め付けるとワッシャの切り起こし部分がワッシャの切りかき部分に収まり、ナットが切りかき部分を通過すると、復元力により切り起こし部分が起き上がりナットの側面に突っ張り効果を与える事でナットの緩みを防止するものである。In short, when the nut is tightened, the cut and raised part of the washer fits into the cut part of the washer. Is to prevent.
