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. Fyrirmyndarval
Líkanið vísar aðallega til þvermáls og leiðar skrúfunnar. Samkvæmt vinnslukröfum, nákvæmni og tæknilegum kröfum vélbúnaðarins er upphaflega ákveðið líkan sem er örugglega þörf. Að lokum, mundu að athuga það. Ef hönnunin uppfyllir kröfur, endanleg lögun
2. Val á nákvæmni blýskrúfa
Vegna þess að nákvæmni breytur skrúfunnar hafa bein áhrif á hlutina sem unnar eru af vélinni, er almennt aðeins nauðsynlegt að standast nákvæmni sannprófun ef hún uppfyllir kröfurnar. Það er líka punktur að skrúfunni er skipt í 7 nákvæmnistig, það hæsta er fyrsta stigið, sem lækkar í röð.
3. Um val á skrúfustuðningsaðferð
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.
