Description

ボディボルトとヘッドボルトの接続技術と緩み防止技術Body bolt and head bolt connection technology and loosening prevention technology

ヘッドボルトの先端に割りピンの穴を開けたヘッドボルトHead bolt with a split pin hole in the head bolt tip

今までの割りピンの役割はナットの脱落防止であったが、ヘッドボルトを使用することにより、従来の割りピンの穴は固定されていたがヘッドボルトを使用すると割りピンの穴の位置を自由に調節できるので緩み防止と脱落防止が出来る。Until now, the role of the split pin has been to prevent the nut from falling off. By using the head bolt, the hole of the conventional split pin was fixed, but if the head bolt is used, the position of the hole of the split pin is free. It can be adjusted to prevent loosening and falling off.

課題を解決する為の手段Means to solve the problem

ナットの長さと接合されたボルトの割りピンの穴がのぞく所までの長さを同じにして穴にピンを差し込む。実際にはバネ座金の厚みを考慮する。Insert the pin into the hole so that the length of the nut is equal to the length of the hole where the split pin of the bolt is inserted. Actually, the thickness of the spring washer is considered.

考案の効果Effect of device

ナットの脱落による事故の防止Preventing accidents due to nut removal

考案の実施するための最良の形態Best mode for carrying out the invention

ボディボルトとヘッドボルトの先端を２〜３ミリ半月状に削りヘッドボルトの回転を止める。その後ナットを装着しヘッドボルトの穴にピンを差し込む。The tip of the body bolt and the head bolt are shaved in a shape of 2 to 3 mm, and the rotation of the head bolt is stopped. Then attach the nut and insert the pin into the head bolt hole.
