Common fault classifier and ruled out

The common malfunction and eliminate 2018 - classifier 11 - 15 1 gear box fever or 'smoking causes: gear box of oil, poor lubrication, oil. Overload use. Fault transmission body itself. Excluded methods: improved lubricating or an oil change. Control the load transmission design or improvement. By 'oil fired', 'glue', 'hot plastic deformation such as specific analysis of symptomatic treatment. 2 gearbox vibration and noise cause: bad tooth contact surface. Lateral clearance is appropriate, axial channeling move. Ultra precision bevel gear. Method: adjust the contact area. Adjust the clearance, eliminate rash move. Replace the bevel gear. 3 bevel gear tooth root crack or broken reasons: bad tooth contact surface. Lateral clearance is appropriate, axial channeling move. Ultra precision bevel gear. Method: adjust the contact area. Adjust the clearance, eliminate rash move. Replace the bevel gear. Thermoplastic deformation and 4 gear agglutination occurred reasons: poor lubrication, less oil, no oil. Highway overload is used. Elimination method: cleaning tank, an oil change. Speed control, the control of load or design improvements. 5 gear causes severe pitting and spalling: bearing clearance is too large, bearing wear. Bad material or heat treatment. Overload use. Excluded methods: repair or replace the bearing. Improving material, heat treatment. Control the load. 6 gear wear serious occurrence reasons: protection seal. Impurities in oil, oil. Bad material. Method: strengthen the protective seal. Cleaning oil change. Choose wear-resisting material. 7 rolling bearing fever abnormal noise causes: poor lubrication, oil shortage badly worn. The transverse end flange bolts loose teeth. Cooperate with loose, clearance increases. The upper adjusting nut thread tooth. Excluded methods: come on in time, short of oil. Tapping change again big bolt. Changing a repair. Handle shaft head, car wire again, change the nut. 8 destroyed or drop the body swing reason: powder concentrator's blade blade quality is bad, weight is not consistent. Blade fixed bolt is loose. Installation is not straight, generate upward or downward deflection. Method: the replacement blades, weighing uniform installation. Check the bolt, washer screw down the bolt. Adjust the installation position. 9 classifier causes of current suddenly: lower or upper rolling bearing burn out. Flange deformation, broken card dead. Feed mixed with large pieces of debris in the upper die and are exported. Vertical shaft bottom big nut loose, and are the hub. Method: check change of bearing. Check the change of flange. Removal of impurities. Tighten the nut. Common faults: fan bearing vibration. Ten different fan and motor shaft causes heart: impeller imbalance. Import and export air door fan is not in the correct position. Foundation stiffness were not strong enough. Anchor bolt is loose. The fan impeller of formation. Method: seek is making two axis concentric. Balance correction. Adjust good throttle position. Strengthen basic, increase rigidity. Check and tighten the bolt. Open access MenQing ash after downtime.
