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. Mudeli valik
Mudel viitab peamiselt kruvivarda läbimõõdule ja juhtmestikule. Tööpingi töötlemisnõuete, täpsuse ja tehniliste nõuete järgi määratakse esmalt välja mudel, mida kindlasti vaja läheb. Lõpuks ärge unustage seda kontrollida. Kui disain vastab nõuetele, siis lõplik kuju
2. Juhtkruvi täpsuse valik
Kuna kruvi täppisparameetrid mõjutavad otseselt masinaga töödeldavaid osi, on üldjuhul vaja täpsuse kontroll läbida ainult siis, kui see vastab nõuetele. Samuti on punkt, et kruvi on jagatud 7 täpsusastmeks, kõrgeim on esimene tase, mis väheneb järjekorras.
3. Kruvi tugimeetodi valikust
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.
