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. Cov qauv xaiv
Cov qauv feem ntau yog hais txog txoj kab uas hla thiab cov hlau lead ntawm cov ntsia hlau pas nrig. Raws li cov kev cai ua, precision thiab kev xav tau ntawm cov cuab yeej siv tshuab, cov qauv uas xav tau yog thawj zaug txiav txim siab. Thaum kawg, nco ntsoov xyuas nws. Yog tias tus tsim ua tau raws li qhov yuav tsum tau ua, cov duab kawg
2. Kev xaiv cov hlau lead precision
Vim tias qhov ntsuas tsis raug ntawm cov ntsia hlau muaj qhov cuam tshuam ncaj qha rau cov khoom ua tiav los ntawm cov cuab yeej siv tshuab, feem ntau tsuas yog tsim nyog kom dhau qhov tseeb yog tias nws ua tau raws li qhov yuav tsum tau ua. Kuj tseem muaj qhov taw qhia tias cov ntsia hlau tau muab faib ua 7 theem ntawm qhov tseeb, qhov siab tshaj plaws yog thawj theem, uas txo qis hauv kev txiav txim.
3. Hais txog kev xaiv cov ntsia hlau txhawb txoj kev
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.
