The way to Detect And Repair Ball Screw?
A ball screw is among the most superior ball screw repair frequently made use of tool of mechanical transmission factors and precision machining, its key operate will be to change rotary movement into linear motion or force-torque to axial frequently, both of those qualities of significant precision, high efficiency and reversibility. On account of its modest friction resistance, the ball screw is widely employed in numerous precision tools and instrument industries!
You will find a lot of varieties of glitches from the ball screw, and there is no fixed model. Some problems are gradual failures, there must be considered a enhancement method, together with the growing usage of a lot more plus much more really serious time; from time to time a unexpected failure, typically does not have obvious signs of unexpected, this failure is usually a variety of unfavourable elements plus the resulting exterior interactions. Thus, the right examination to ascertain the cause of serious problems will be the premise of rapidly and correct maintenance. For ball screw fix also will have to be regarded.
1 Ball screw, nut and aid clearing system Detection and restore
In the event the CNC machine tool reverses mistake and superior positioning precision, quadrant mark is unstable, the 1st thing to detect the method screw there exists a variance. Detection strategy: indicator that has a ball for the centre close in the hole on the screw, axial measurement screw, a dial gauge piece measuring the perform table. Screw rotation, observing the 2 blocks over the indicator dial demonstrates, in accordance with adjustments in different values ensure the situation on the mistake.
2 FAG Detection and restore of clearing screw bearings
In case the indicator dial actions the screw inside the ball screw forward and reverses rotation the pointer swing does not, that there is no screw movement. When the swing cursor indicator suggests the channelling screw phenomenon. The indicator dial actions the primary difference amongst the most and minimum values which might be the axial distance with the screw. At this point, we are going to check out whether the bearing back bearing assistance is locked, if the bearing is worn out or not, if the preload washer bearing is acceptable or not. Should the bearing is Ok, just re-load the pre-loaded gasket. Should the bearing is damaged, the bearing has to be replaced, re-loaded together with the pre-load washer, after which you can supported once again. The axial movement in the guide screw is dependent mainly to the precision in the bearing preload. Quite possibly the most perfect ailment of your accuracy of your installation of screw rods is there is no optimistic and destructive clearance, and the aid bearings need to be about 0.02mm interference.
3 FAG Detection and routine maintenance of gaps involving pairs of two ball screw nuts
By inspection, if an mistake is confirmed, it is not caused by the movement of the direct screw. Need to take into account whether or not the screw nut, the hole among the two, Detection of the problem mainly along with the detection from the guide screw transferring the same. Worktable linked with dial and nut indicator, ahead and reverse screw rotation, detect most clearance involving screw and nut then be altered.
4 FAG inspection and maintenance of one pair nuts
For a single ball screw nut, the gap among the screw pair along with the nut can not be modified. In the event the direct screw nut is detected, there is certainly a niche. Initial, test the guide screw and thread bow nut Are worn, like serious put on, have to replace the full list of guide screw nuts.
If smaller put on is detected, a larger diameter ball is often replaced to repair it. First, the utmost clearance from the detected pair nut screws is converted to a rise in ball diameter and then geared up with the proper ball to regroup. This type of servicing is complicated and demands a long time and demands a large stage of engineering.
five The beam flanges and tables are related, you will find gaps still there
This issue may be very easily ignored for some time, reciprocating the engine, loose screw Fala disc hole, check the hole in the failure factor with the screw to exclude, to stop repairs.
6 Ball screw nut movement is not abnormal noise, clean maintenance and various failures
Ball screw nut movements aren't easy along with the sound is just too large, mostly due to very poor lubrication, but sometimes it could be for the reason that the servo motor push parameters are certainly not adjusted thoroughly induced.
