Everyone knows that the ball screw is a highly efficient and precise transmission element. Now it has its presence in the industry. It can almost be said that the use of screw has been seen everywhere. Because it has the advantages of high rigidity, no gap, synchronization, high sensitivity, simple maintenance, long life, etc., it is very suitable for the requirements of various industrial production equipment. But there are so many kinds of it, how do I choose the right screw? Let's take a look:
1.モデルの選択
モデルは主にねじ棒の直径とリードを参照します。 工作機械の加工要件、精度、技術要件に応じて、確実に必要なモデルが最初に決定されます。 最後に、それを確認することを忘れないでください。 デザインが要件を満たしている場合、最終的な形状
2.送りねじの精度の選択
ねじの精度パラメータは工作機械で処理される部品に直接影響を与えるため、通常、要件を満たしている場合にのみ精度検証に合格する必要があります。 ネジが7段階の精度に分かれている点もあり、最高は最初のレベルで、順番に減少します。
3.ネジ支持方法の選択について
In the process of designing CNC machine tools, the support method of the screw rod usually chooses "fixed-support" or "fixed-fixed". The "fixed-support" support method is relatively easy to assemble, with better rigidity and high accuracy. It is mainly used in environments with medium speed, large stroke and heavier load; the "fixed-fixed" support method is relatively difficult to assemble. With good rigidity and high precision, it is often used under high speed, large stroke and heavy load environment.
