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. Odabir modela
Model se uglavnom odnosi na promjer i vod vijčane šipke. Prema zahtjevima obrade, preciznosti i tehničkim zahtjevima alatnog stroja, prvotno se određuje model koji je svakako potreban. Konačno, ne zaboravite to provjeriti. Ako dizajn zadovoljava zahtjeve, konačni oblik
2. Odabir preciznosti zavrtnja
Budući da parametri preciznosti vijka imaju izravan utjecaj na dijelove koje obrađuje alatni stroj, općenito je potrebno proći provjeru točnosti samo ako ispunjava zahtjeve. Također postoji točka da je vijak podijeljen na 7 razina točnosti, najviša je prva razina, koja se smanjuje redom.
3. O izboru metode potpore vijcima
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.
