What will become of screw bearing has a problem, the effect of screw bearing problem is analysed and a solution

Screw bearing as a whole, its work on different components to complete the cooperation, the long run, will inevitably be the parts problem, so, screw bearing more common is the problem? There is something wrong with the screw bearing? How to solve these problems we then? Let's take a look at together. A common question 1, screw bearing, gap problem ( 1) Double nut. Ball screw in operation have space between the double nut pair, the ball bearing wear. （ 2) Single nut. Single ball screw nut pair wear gap is produced. （ 3) Nut and flange plate workbench has no fixed firmly, produce the gap. The problem generally easy to be found, because of long-term reciprocating motion machine, fixed flange screw loosening clearance. 2, servo drive problems generally when servo drive parameters didn't adjust good, gain bigger, servo machine problems will be easily. 3, bad lubrication problems generally include poor lubrication bearings and screw nut pair, because many machine after many years of operation, screw nut, the automatic lubrication system often jams, cannot be automatic lubrication and problems. Each ring problems should not be underrated, because it can directly or indirectly affect the bearing work, so these problems will be how to impact the lead screw bearing? Then we look at the following content. Second, the influence of the lead screw bearing problem 1, poor positioning accuracy, processing parts size is not stable when the lead screw bearing problems will make the lead screw bearing positioning accuracy, processing of parts size becomes unstable, the failure is mainly due to the above mentioned gap is too big. Ball screw nut pair and its supporting system of wear due to long running clearance, will directly affect the rotation of the nc machine tool precision and rigidity. 2, screw bearing movement is not smooth, the noise is too large in the work, such as noise and vibration of the machine tool in the detection of mechanical transmission parts is no problem, first of all, want to consider to the problem of poor lubrication, because many machine after many years of operation, the screw nut, the automatic lubrication system often jams, automatic lubrication. As well as servo drive problems, namely servo drive parameter discrepancy and practical problem. Three, problem solution 1, clearance problem solution ( 1) Do the length check nut wear and maintenance actions according to the wear situation, should be replaced in a timely manner when worn screw nut, can by changing the diameter of the ball when wear slightly to repair the wear and tear. （ 2) When the flange screw loose produce clearance, timely and screw down the screws, so as not to have a greater impact. 2, servo drive servo motor driver gain problem solution parameters are not suitable for the actual operation condition, adjust gain after the number, can eliminate the vibration and crawling malfunction. 3, bad lubrication problem solution can add resistance to high temperature, high speed bearing, nut grease, bearing grease can guarantee the normal operation for several years, nut. High intensity running for a long time will make the screw bearing appear problem, there is something wrong with the screw bearing? Its precision will become worse, produced the corresponding parts size becomes unstable, noise can also be bigger. So it seems, is very important to maintain really screw bearing.
