Gear motor & # 8203; A common failure 1 of gear speed reducer. Reducer's abnormal fever reducer refers to the abnormal fever reducer bearing parts or shell parts fever, beyond the normal temperature scale, more common is bearing parts of the fever. Possible reasons: over load operation of the gearbox, bearing wear, the spare parts such as bearings, gears and shaft device, voltage too high or too low, a short period of time, suspend, smooth owe good, etc. In the production of steel rolling, super load operation may cause more frequently attack speed reducer failure, and is the most common bearing wear. 2. Reducer and abnormal sound is refers to the speed reducer of oscillations and noise increases obviously, beyond the normal promised to scale, or there are abnormal noise and vibration. Possible cause: the cause of the abnormal vibration and noise reducer attack many, mainly include: gear and bearing damage, there's a foreign body in gear mesh part gets stuck, reducer and motor alignment error between the larger, owe good of gearing device, bolt looseness, unclean smooth oil such as impurities. 3. Oil is mainly reducer bearing end cover bearing, sealing surface or shell combined with the status of the surface is smooth in areas such as the oil leakage. Possible reasons: sealed owe good, casing deformation, casing damage, etc. ; May also be in gear transmission, heating because of conflict, leading to a high oil temperature rise, leakage of oil become thin and short. Speed reducer failure associated with too many elements, any link to present problems could lead to a reducer fault attack, so after daily protection and maintenance condition, equipment failure of maintenance quality is very important. But with the protection of the reducer is difficult, because the machine of decelerate of trigger fault elements are often in the inside of the box body to speed reducer, the reducer casing internal in production operation is difficult to see. How to find problems as early as possible, to prevent the disturbance expansion is very important. Precautions 1. Reducer of the selected equipment quality directly affect the use of equipment condition, the resolution equipment using life. Accordance with the requirements of field operation condition, load such as choosing suitable types of reducer, choose good quality, good promise, have corresponding technical advantage of manufacturers supply, and ensure the quality of the reducer. 2. Reducer device debugging speed reducer device improperly will affect the normal reducer is applied, the device deceleration machine should be pay attention to: (1)Reducer is necessary device in cement flat on the base of anchor bolt is necessary to consolidate and shock; （2)It is necessary to ensure that the motor -Reducer -Rig alignment between each other; （3)Device must view its smooth system, after the completion of smooth right amount, make sure all the key position to ensure smooth oil cleanliness requirements. And according to the rules of the rear can put into trial run. 3. Reducer protection maintenance equipment daily protection is against failure and prevent the disturbance of the crucial, reducer daily protection needs pay attention to the following aspects: 1)Strengthen the training of the equipment to protect personnel. Many equipment to protect personnel no theoretical foundation, some knowledge of cognition and illegal act sloppily phenomenon may be present, so need to strengthen the timing for the scene to protect staff training, training should be short and easy to understand and have maneuverability, avoid by all means no essence of pure theoretical bases, enhance their professional knowledge and technology. 2)Strengthen the daily check. On the basis of smooth operation & otherFive set throughout the &; Standard, keep smooth and maintenance work of reducer, do each deceleration machine has a responsibility to check regularly, group experienced personnel for regular spot checks, if found reducer show some abnormal phenomenon, should immediately stop operation, timely repair processing, to prevent the disturbance expansion. Together, after each check and repair processing, make records, for each reducer has a comprehensive and clear cognition. View mainly include: the content of the view to slow down the oil temperature, bearing temperature is in the promise to scale, during which the size of its promised to appropriate adjustment should be done according to the ambient temperature; Check the reducer in the process of operation with or without abnormal vibration and sound; Check reducer and combining with the surface and bearing end cover bearing without oil leakage phenomenon, if there are processed in a timely manner; Regularly check the smooth oil cleanliness; Through investigation on reducer to suspend operations, hole to check the gear, shaft and other internal components. For bearing damage is the most common cause of reducer fault elements, and bearing parts are difficult to detect,Need to stop open bearing end cover can see, spending a lot of time), it can open a investigation on reducer bearing end cover, convenient to check at any time. Check the reducer external environment health, make its work in the better environment as much as possible. 3)Repair and fault after reducer of device operation. Attack after the failure of the gearbox, to analyze the site specific investigation, find out the cause of the problem, keep records of test conditions. Replace damaged parts together, demand correction of parts necessary correction, can't find in a short period of time to fair use is reluctant to use, strict in accordance with the rules of device, ensure that the casing clean, completes the gap adjustment. Else, body surface and bearing end cover bearing sealant altered in moderation, don't think the more the better, too much can lead to bearing outer ring, wear casing bearing hole, also can make the oil hole plug, smooth and trigger a big failure. Right device operation, the protection and maintenance regularly, ensure that the essence of protection personnel, can largely reduce the failure frequency, ensure the production smoothly.
