ばねの形状と寸法許容差
- 巻方向：右巻
- 外径許容差：仕様表に記載
- 自由長：参考値として許容差をつけない
- ばね定数：参考値として許容差をつけない
- 最大荷重の許容差：±15％
- 総巻数：仕様表に記載、参考値として許容差をつけない
ばねの選定方法
① ばねのスペースからコイル径を決める
② 必要な荷重より大きい最大荷重規格のばねを選ぶ
③ ばねの使用高さを決める
計算例
条件 穴径φ62の中にCWSを入れ、ベアリングに194Nの予圧を与えたい。
① 外径φ62以下で近い外径寸法の「WP61.2P＊＊＊N7」を選択。
② 最大荷重が必要荷重より大きい「WP61.2P240N7」を選択。
③ 最大荷重時高さ12.3mmのとき、最大荷重240N ばね定数31.5N/mmなので
最大荷重と必要な荷重の差を求める
⇒240N − 194N ＝ 46N
荷重の差をばね定数で除算し高さの差を求める
⇒46N ÷ 31.5N/mm ≒ 1.5mm
高さの差と最大荷重時高さの和より、使用高さが決まる
⇒1.5mm + 12.3mm ≒ 13.8mm
これにより194N予圧時の使用高さは13.8mmとなる。
ばねの形状と寸法許容差
CWSは構造上、ばね定数の変化点が存在します。この変化点は山数や山の高さなどの仕様により変化点位置は異なります。
一般的に山数が少なく、山形状の高さが大きいほど初期たわみにおいて、ばね定数の小さい範囲が占める割合が大きくなります。変化点以降のばね定数が大きい値をカタログ値と掲載しております。
