How you can Detect And Repair service Ball Screw?

A ball screw is among the most 20mm ball screw normally used resource of mechanical transmission factors and precision machining, its most important operate would be to transform rotary movement into linear movement or force-torque to axial continuously, both of those traits of substantial precision, higher performance and reversibility. As a consequence of its little friction resistance, the ball screw is commonly utilized in numerous precision devices and instrument industries!



You will find many varieties of errors inside the ball screw, and there is no mounted model. Some blunders are gradual failures, there ought to be a improvement method, with the increasing use of more plus much more significant time; from time to time a unexpected failure, typically does not have clear indications of sudden, this failure can be a assortment of unfavourable components plus the resulting exterior interactions. Therefore, the correct check to ascertain the reason for authentic glitches could be the premise of rapidly and accurate routine maintenance. For ball screw mend also must be thought of.

one Ball screw, nut and guidance clearing program Detection and maintenance

Once the CNC device device reverses mistake and higher positioning precision, quadrant mark is unstable, the primary point to detect the procedure screw there exists a variation. Detection system: indicator which has a ball for the centre close in the gap on the screw, axial measurement screw, a dial gauge piece measuring the perform desk. Screw rotation, observing the two blocks over the indicator dial reveals, based on changes in several values validate the location of the mistake.

2 FAG Detection and repair of clearing screw bearings

In case the indicator dial measures the screw inside the ball screw forward and reverses rotation the pointer swing isn't going to, that there's no screw motion. In case the swing cursor indicator suggests the channelling screw phenomenon. The indicator dial actions the real difference concerning the maximum and least values that happen to be the axial distance of the screw. At this point, we are going to look at if the bearing back again bearing guidance is locked, whether or not the bearing is worn out or not, if the preload washer bearing is suitable or not. In case the bearing is Alright, just re-load the pre-loaded gasket. In the event the bearing is broken, the bearing really should get replaced, re-loaded using the pre-load washer, and afterwards supported yet again. The axial motion of the direct screw relies upon mainly over the precision from the bearing preload. The most ideal problem with the precision with the set up of screw rods is usually that there is absolutely no positive and negative clearance, and the guidance bearings should be about 0.02mm interference.

three FAG Detection and routine maintenance of gaps involving pairs of two ball screw nuts

By inspection, if an mistake is verified, it truly is not attributable to the movement of your guide screw. Ought to contemplate whether the screw nut, the hole in between the 2, Detection of this condition mainly with all the detection from the guide screw going the exact same. Worktable related with dial and nut indicator, forward and reverse screw rotation, detect utmost clearance between screw and nut then be modified.

four FAG inspection and routine maintenance of single pair nuts

For 1 ball screw nut, the hole involving the screw pair along with the nut can not be adjusted. If your lead screw nut is detected, there exists a niche. 1st, look at the direct screw and thread bow nut Are worn, like really serious put on, really need to swap the full set of guide screw nuts.

If little wear is detected, a larger diameter ball might be changed to repair it. To start with, the utmost clearance with the detected pair nut screws is converted to a rise in ball diameter after which geared up using the proper ball to regroup. This type of routine maintenance is advanced and demands quite a long time and involves a superior degree of technologies.

five The beam flanges and tables are linked, you will find gaps even now there

This problem could be very easily dismissed for some time, reciprocating the engine, unfastened screw Fala disc gap, check the hole during the failure factor with the screw to exclude, to prevent repairs.

six Ball screw nut movement isn't extreme sound, smooth servicing together with other failures

Ball screw nut actions are certainly not clean and also the sound is simply too large, generally due to poor lubrication, but in some cases it might be for the reason that the servo motor drive parameters usually are not modified effectively caused.
