Causes of motor shaft broken shaft fault treatment and surface wear
Theoretically, it can be repaired.motor shaftNeck fracture,In the maintenance process, welding and post-weld heat treatment are important links. Before welding, the original shaft and the machined shaft head must be carefully cleaned, and all oil and other impurities that generate hydrogen must be strictly removed.
Knot can be used when welding857Electrode, diameter3.2. Before welding, dry the electrode at the heat source2Hours, then it can be removed from the electrode as needed,In the direct current welding machine, the reverse connection method is used for welding. First of all, the motor rotor shaft and processing shaft head in300Preheat at ℃, then hang on the roller frame, start symmetrical welding, and fill layer by layerUShaped groove.
motor shaftDuring welding, the current value can be90-100,Slow welding prevents the rotor shaft from overheating,Immediately after welding, use a gas cutting torch at a distance from the welding position100-120Heating area in the range of millimeters, while continuously rotating the rotor shaft to make it evenly heated and avoid deformation,When the heating temperature reaches500~600℃, please keep1hours, and then hang it in300℃ in the oven to allow it to cool to normal temperature.
motor shaftThree possible causes of surface wear:
1.Due to non-standard, untimely, on-site installation, maintenance, lubrication and other reasons, the equipment is prone to rapid wear;
2.Affected by vibration, pressure, impact and other forces, it will cause impact wear of matching parts,Due to the high strength and poor concession of metal materials, long-term operation will inevitably cause the gap to continue to increase, resulting in wear, rupture, fracture and other phenomena, which is inevitable.
3.The manufacturing quality is not high, the heat treatment does not meet the requirements, etc., causing wear and tear, and the shaft head is broken in severe cases.
motor shaftAfter wear, traditional solutions are used, such as machining after repair welding, inlay bushing, electric brush plating, spraying, pitting, scraping, etc. Although these methods have met the production needs to a certain extent, they cannot be solved fundamentally. For this problem, please avoid the wear of the motor shaft, please pay attention to the above reasons for the wear of the motor shaft, use the motor shaft reasonably, and perform regular maintenance.
