MHI HASEG CO., LTD. is a member of Mitsubishi Heavy Industries Group, and Shanghai Lingyouhui Technology Co., Ltd. has introduced power transmission equipment from Mitsubishi Heavy Industries' power transmission department to China. On April 1, 2015, Mitsubishi Heavy Industries' power transmission department was reorganized into Mitsubishi Heavy Industries Hasegawa Co., Ltd. MHI HASEG CO., LTD., which focuses on the design, development, and production of large gearboxes. The reducer produced by Mitsubishi Heavy Industries Hasegawa MHI HASEG has the characteristics of adjustable backlash, five stage variable speed, stable rotation, low noise and low vibration. Widely used in precision machinery, steel rolling machinery, semiconductor manufacturing equipment, aerospace steel, rubber, printing, textile machinery and other industries.
The fault diagnosis of Mitsubishi Heavy Industries reducer can be approached from multiple aspects, and the following are some common fault diagnosis methods:
Check the integrity of the componentsCheck for cracks or damage to the gearbox casing, as well as loose connections between various components such as anchor bolts and end cap bolts. If there are loose bolts, it may lead to increased vibration, which can seriously affect the normal operation of the gearbox.
Check the condition of the lubricating oilCheck the oil level gauge to confirm if the oil level is normal. Low oil level may cause poor lubrication and accelerate component wear; If the oil level is too high, it may cause problems such as oil temperature rise and oil leakage. At the same time, observe the color and transparency of the lubricating oil. If the oil becomes black, turbid, or has obvious impurities, it indicates that the lubricating oil has been contaminated or deteriorated and needs to be replaced in a timely manner.
Check the sealing areaFocus on checking for signs of oil leakage at the shaft extension and end cap joint surface. Aging and damage of seals are common causes of oil leakage. If oil leakage is found, the seals should be replaced in a timely manner to prevent excessive lubricant leakage from affecting the performance of the gearbox.
Monitor the running soundDuring the operation of the gearbox, carefully monitor the internal sound. During normal operation, the gearbox should produce a smooth and even running sound. If there is a sharp whistling sound, it may be due to poor gear meshing or damaged bearings; If there is a periodic knocking sound, it may be due to gear breakage, wear, and other issues.
measure temperatureMeasure the oil temperature and bearing temperature of the gearbox using a thermometer or temperature sensor. In general, the oil temperature during normal operation of the gearbox should not exceed 80 ℃, and the bearing temperature should not exceed 90 ℃. If the temperature is too high, it may be caused by excessive load, insufficient lubricating oil, or cooling system failure. It is necessary to promptly investigate and solve the problem to avoid component damage.
Detecting vibration conditionsMeasure the vibration amplitude and frequency of the gearbox using a vibration tester. During normal operation, the vibration value of the gearbox should be within the specified range. If the vibration amplitude suddenly increases, it may be caused by gear wear, bearing damage, or unbalanced installation of the reducer. By analyzing the vibration frequency, the type of fault can be further determined, such as low-frequency vibration may be related to bearings, and high-frequency vibration may be related to gear problems.
Detect speed and torqueMeasure the output shaft speed of the gearbox using a tachometer to ensure it meets the design requirements. At the same time, the output torque is detected by a torque tester to determine the transmission performance of the gearbox under different loads. If the speed is abnormal or the torque output is unstable, it may be due to a malfunction in the internal transmission components, which affects power transmission.
Check the transmission accuracyFor reducers with high-precision transmission requirements, the transmission accuracy of the reducer can be determined by measuring indicators such as the angular accuracy and positioning accuracy of the output shaft. If a decrease in transmission accuracy is found, it may be caused by gear wear, worm gear wear, and other reasons, and timely maintenance or replacement of components is needed.
Check the motor current and voltageUse an ammeter and voltmeter to monitor the current and voltage of the motor connected to the gearbox. If the current increases abnormally or the voltage is unstable, it may be due to excessive load on the reducer, motor failure, or electrical system problems. Further investigation is needed to avoid damage to the motor and reducer due to overload or abnormal voltage.
Check electrical componentsCheck the electrical control components of the gearbox, such as thermal relays, contactors, etc., for any abnormal phenomena such as overheating or ignition. At the same time, check the performance of the electromagnetic brake to ensure its normal operation and reliable braking. If electrical components fail, it may affect the start stop and operation of the gearbox, and even cause safety accidents.
Perform oil testingRegularly extract lubricating oil samples from the gearbox and send them to a professional laboratory for oil analysis. By detecting indicators such as metal debris content, viscosity, acidity, etc. in the oil, the wear of internal components of the gearbox can be understood. For example, if the iron filings in the oil are too high, it may indicate severe gear or bearing wear; Abnormal viscosity or changes in acidity or alkalinity may affect the lubrication performance of lubricating oil, and timely measures should be taken.
