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. Model tanlash
Model asosan vint novda diametri va qo'rg'oshini nazarda tutadi. Mashina asbobining ishlov berish talablari, aniqligi va texnik talablariga ko'ra, dastlab aniq kerak bo'lgan model aniqlanadi. Nihoyat, tekshirishni unutmang. Agar dizayn talablarga javob bersa, yakuniy shakl
2. Qo'rg'oshin vintining aniqligini tanlash
Vintning aniq parametrlari dastgoh tomonidan ishlov beriladigan qismlarga to'g'ridan-to'g'ri ta'sir qilganligi sababli, odatda talablarga javob bersa, aniqlikni tekshirishdan o'tish kerak. Bundan tashqari, vintni 7 aniqlik darajasiga bo'lingan nuqta bor, eng yuqori - birinchi darajali, bu esa tartibda kamayadi.
3. Vintni qo'llab-quvvatlash usulini tanlash haqida
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.
