【正文】 ving bee a ditch , the rotor blows in , brings about discharging , axle bearing since the brush is pink to lack for lube, these all are that not yet timely upkeep brings about。 The electric fan long range cooling down does not rotate , even, the ventilating duct blocks up , the electric fan electric motor cannot rotate , the result electric motor burns through。 The rotator does not lubricate because of axle bearing , the hot shot , final electric motor of end cap adopts a baby live high and low bringing about, electric motor fever derides even. 南通職業(yè)大學(xué)機(jī)械系畢業(yè)論文 34 That the mains input 7 mains inputs are examined is examined is a very important link. Need to examine that the mains input is regular or not first, this is the most important condition of regular job of numerical control machine tool, as long as voltage is abnormal , bring about malfunction closing down surely , bring about system duty chaos even. Have many machine tool or testbed have tested run in abroad , transport to in the homeland assemble the day afer tomorrow being abnormal, problem being a power source also often. And then definitely not let an accident expand when examination, ensure that part carries out power source examination reliable, for instance , reaching loads down first, measure service voltage , every control voltage value alone, the range expanding measurement. But the power source module is power dissipation big , easy to go wrong, great majority condition power failure is to arouse from the loads. Need to pay attention to fusible cutout replacement, because of the fusing line is to have protected a stream39。s, factor only row must remove loads have aroused a stream before new fuse in replacement. Examine that one side examines the power source charging line time the power source , also need to examine that voltage, is simultaneous by its if the nothing power source part supplying electricity correctly , want to examine that those should not get if the electricity part have also had an electricity too , want to pay attention to arriving at having got that voltage really or not too specially. Some factories one equipment 24 V and 5 V voltage insert on the contrary may actual analysis pass, 24 V go up not to add to 5 V circuits at all. Go to change board , to change film being unnecessary such , busy. Two, malfunction phenomenon analysis law Fault analysis is the characteristic seeking a malfunction , special field face related to by it is very broad , analyses and then the cause happening according to catching the analysis being in progress , the law finding out fault to phenomenon. Some factories mark or scar left by a knifecut appear on surface when processing a gear wheel, that the personnel machinery is kept in repair certainly speaks is an electric problem. Only had looked at mark or scar left by a knifecut, but cannot find out a law, active field of electricity thinking work personnel Xiu is therefore electric , the identical control casing is held over , still producing mark or scar left by a knifecut finally. This 南通職業(yè)大學(xué)機(jī)械系畢業(yè)論文 35 problem is measured until VCMD is in progress to the servosystem Zaxis, making clear just now is that Z feeds for 0 , as usual, mark or scar left by a knifecut has , unpacks the chief axis queen since the chief axis oscillation arouses mark or scar left by a knifecut, axle bearing is broken before discovering a chief axis. Still having a few overloads warning is decentraction since clamping the head , resistance is very big when bringing about dress gripping strain makes the workpiece chief axis turn round. Clamping jaw revolution anization has lost efficacy or bringing about the wear sliding with no result , has enlarged workpiece thereby when the chief axis turns round load moment of torsion waits. In short ,a phenomenon39。s appears , requires that the personnel who is maintained poses out judging accurately. For instance , the gear wheel has mark or scar left by a knifecut face to face, we can cut a flat surface , take a look at having mark or scar left by a knifecut or not, take a look at a tool carrier then, again being given to in if Z direction have moving forward, e this to test that being able to use magism to depend on a form. Have mark or scar left by a knifecut, but magism to keep self39。s body unmoved by the form, this has posed a motion aspect not moving , certainly has been another aspect. Therefore, can affirm the mark or scar left by a knifecut being to lay bare the block of wood law arousing since the chief axis vibrates. Want the experiment explaining that the machinery personnel dismantles a chief axis but posing under the condition this is tested being that electricity personnel known number Zaxis has no VCMD. As for electricity personnel, there be no Zaxis VCMD having already explained a problem. Three, the face ply demonstrates and guiding lights analyses law The malfunction information that face ply display provides has been very important , certainly diagnose system has provided the number giving an alarm and characters display , must analyse these information detailedly. These information is information by the fact that the puter simulates reliability , science39。s that system gives out. But the face ply fixes guiding lights or upper guiding lights of printing circuit board is only the information providing we with 南通職業(yè)大學(xué)機(jī)械系畢業(yè)論文 36 a few malfunctions in rough, these information can make us find malfunction occurrence place paratively quic
