Qhov loj rov qab yuam kev ntawm lub pob ntsia hlau yog ib qho teeb meem uas tshwm sim ntau heev. Qhov teeb meem no cuam tshuam rau kev ua haujlwm tau zoo thiab txo qis kev ua haujlwm zoo. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog rau txhua tus kws tshaj lij los tuav cov teeb meem thiab kev daws teeb meem ntawm lub pob ntsia hlau, thiab txo qhov cuam tshuam ntau li ntau tau.
1. What is the reason for the large reverse error of the ball screw?
1. The pre-tightening force of the ball screw is too tight or too loose;
2, the screw shaft coupling taper sleeve is loose;
3. The pre-tightening force of the screw support bearing is too tight or too loose;
4, the screw shaft sliding plate cooperation wedge iron is too tight or too loose;
5. The ball screw has large manufacturing errors or axial movement;
6. the screw shaft slide plate cooperation pressure plate is too tight or too loose;
7. Other mechanical disturbances.
Two. How to remove the wrong direction of the ball screw:
1. Adjust the pre-tightening force and check the axial movement value, so that the error is not greater than 0.015mm;
2. Re-adjust or study from the beginning to make the contact rate reach more than 70 percent . If the 0.03mm feeler gauge is not used, it is qualified;
3. Re-adjust or study from scratch;
4. It is qualified if the 0.03mm feeler gauge does not enter;
5. Repair adjustments or padding;
6. repair and adjustment;
7. Adjust to the surface of each guide rail with lubricating oil;
8. Fasten from the beginning and use a percentage to indicate the repeat test;
9. Sweep away dry and parts.
Pob ntsia hlau yog cov khoom siv siab tshaj -cov khoom sib kis ntawm cov cuab yeej siv tshuab. Nws siab -cov yam ntxwv ua tau zoo ua rau qhov tsis tau muaj dua qhov siab tshaj - ceev pub cov yam ntxwv rau cov chaw machining. Nyob rau tib lub sijhawm, yog tias kev ua haujlwm tsis raug me ntsis, nws yuav tsuas nthuav tawm ntau qhov yuam kev. Kev soj ntsuam yuam kev.
GY muaj ntau yam ntawm cov ntsia hlau thiab txiv ntseej. Vim li cas ho tsis teeb peb qhov kev sib tw linear?
