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. Roghnú múnla
Tagraíonn an múnla go príomha le trastomhas agus luaidhe an tslat scriú. De réir riachtanais phróiseála, cruinneas agus ceanglais theicniúla an uirlis mheaisín, déantar an múnla atá ag teastáil go cinnte a chinneadh ar dtús. Ar deireadh, cuimhnigh é a sheiceáil. Má chomhlíonann an dearadh na ceanglais, an cruth deiridh
2. Roghnú cruinneas scriú luaidhe
Toisc go bhfuil tionchar díreach ag paraiméadair bheachtais an scriú ar na codanna a phróiseálann an uirlis meaisín, ní gá go ginearálta ach pas a fháil sa fhíorú cruinneas má chomhlíonann sé na ceanglais. Tá pointe ann freisin go bhfuil an scriú roinnte ina 7 leibhéal cruinnis, is é an ceann is airde an chéad leibhéal, rud a laghdaíonn in ord.
3. Maidir leis an rogha modh tacaíochta scriú
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.
