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. Pemilihan model
Model terutamanya merujuk kepada diameter dan plumbum rod skru. Mengikut keperluan pemprosesan, ketepatan dan keperluan teknikal alat mesin, model yang pasti diperlukan pada mulanya ditentukan. Akhirnya, ingat untuk menyemaknya. Jika reka bentuk memenuhi keperluan, bentuk akhir
2. Pemilihan ketepatan skru plumbum
Oleh kerana parameter ketepatan skru mempunyai kesan langsung pada bahagian yang diproses oleh alat mesin, secara amnya hanya perlu lulus pengesahan ketepatan jika ia memenuhi keperluan. Terdapat juga satu titik bahawa skru dibahagikan kepada 7 tahap ketepatan, yang tertinggi adalah tahap pertama, yang menurun mengikut susunan.
3. Mengenai pilihan kaedah sokongan skru
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.
