Re-purchase the N220 industrial gear oil of the fully-traded Karamay Oilfield, remove the old oil, and add new oil. The bearing temperature in the above position is 43e, the temperature of the tank is 40e, and the temperature drops by 8e, avoiding an equipment accident. Lubrication problems of the main reducer bearings Whenever the upper cover is opened for maintenance, each bearing needs to add an appropriate amount of sodium-based grease to prevent oil shortage during driving. During repeated inspections, we found that the oil supply between the bearings 97520 and 3620 on the input shaft was small, and the oil easily flowed into the oil tank from the bearing 3620, causing the bearing to heat up and be damaged due to lack of oil. Therefore, we stipulate that before each shift, the mechanics add oil from the oil hole of the input shaft, and refuel every 4 hours during the production process, especially in winter. In the hot summer, it is sometimes found that the two 7624 bearings on the large bevel gear shaft heat up. In this case, open the end cap and fill in some sodium grease in time.
Regular inspection should periodically open the main reducer observation window to check the oil level, the wear of each gear, the screw tightening at the input shaft end and the tightening of the large bevel gear screw. If there is any problem, deal with it in time. Trouble-shooting timely detection and troubleshooting is of practical significance for reducing maintenance costs, saving energy and reducing consumption, improving equipment operation efficiency and improving enterprise economic benefits. The main failures of the main reducer are as follows: (1) The phenomenon of gear tooth surface breakage in the main reducer is rare. Generally, the meshing of the large and small bevel gears is not good or the end face of the small bevel gears on the input shaft is fixed. When the two screws are loose and the fatigue is broken, the gear meshing is poor, and the gear tooth surface is broken. At this time, the deceleration machine emits a large abnormal noise, and should stop in time, open the observation window to observe the gear damage. If the situation is serious, open the top cover of the reducer, remove the broken screw and replace it, and use the grinding wheel to repair the fracture surface of the tooth surface. . Precautions: Drill holes in the screw caps fixed at the shaft end of the small bevel gear, and connect them with a stainless steel welding rod to prevent loosening. (2) Bearing heating should be patrolled twice at least for the main reducer bearing parts. If the bearing temperature of each part is higher than 55e, the sodium base grease should be added in time; if it is higher than 65e, it should be stopped or replaced in time to avoid causing Larger losses.
