The following are the solutions for excessive vibration in BLED153 - 473 - 3KW reducer load debugging, which usually requires professional operation:
Internal parts inspection and repair
Gear problem handling : For example, check the gear tooth surface wear, glue, pitting, grinding, deflection, release, broken teeth, etc., as well as whether the gear and shaft are in good coordination. For gears with severe wear, professional knowledge and skills are required to replace gears with shaft matching tolerances, interference, etc. to ensure the installation accuracy and meshing effect of new gears, and avoid new problems caused by improper installation.
Handling bearing problems : Check the wear condition and gap size of the bearing, determine whether the rolling element of the rolling bearing has lump surfaces, whether the fixing frame is damaged, whether the sliding bearing alloy is worn, wear-off or melted, etc. Professional personnel need to make accurate judgments based on experience and professional tools. When replacing the bearing, the correctness of installation and reasonableness of clearance adjustment should be ensured, otherwise it may affect the normal operation of the reducer.
Inspection and replacement of shafts : Professionals use professional measurement tools to check whether the shaft is deformed and worn, and determine whether the strength and hardness of the shaft meet the requirements. For bent or damaged shafts, calibration or replacement is required on professional equipment. In addition, for example, when dealing with the keyway wear of the output shaft, whether it is replacing the output shaft, repairing the keyway or using the keyway sleeve, it is recommended to do it under the guidance of a professional.
Balance correction : Perform dynamic balance and static balance inspections on the rotating parts of the reducer, especially those rotating at high speed. Professionals use professional balance detection equipment to determine the position and extent of the imbalance and correct the imbalance by adding or removing the balance mass in place, which requires professional knowledge and experience to ensure the accuracy of the balance correction.
Vibration spectrum analysis : Use professional vibration spectrum analysis instruments to analyze the vibration of the reducer and determine the frequency, amplitude and other parameters of the vibration, so as to accurately determine whether the cause of the vibration is mechanical looseness, misalignment, rotational stall or other problems. Professionals are able to develop effective solutions based on the analysis results, and it is difficult for non-professionals to accurately interpret and utilize this data.
Accurate adjustment of coupling : Remove the coupling and reassemble it as required to ensure that the center line of the reducer output shaft is in a straight line with the center line of the connecting equipment, and the center line of the coupling column pin hole is parallel to the center line of the inner hole. Professional measurement tools (such as a dial meter, etc.) are required for accurate measurement and adjustment to ensure the installation accuracy of the coupling and reduce vibration caused by misalignment.
