How to carry out daily maintenance and maintenance of the reducer, what is the general standard of the lubricating oil used in the reducer, and what is the lubrication method of the reducer. Here we will introduce these issues so that the majority of reducer users can know how to maintain Our reducer and equipment, give you a professional reference and advice.
This reducer generally uses medium-duty industrial gear oils L-CKC5903 and L-CKC220 in GB320. The following table shows the recommended viscosity grades of lubricating oil (mineral oil) when the reducer is at different ambient temperatures.
a.Oil level
The reducer is generally lubricated by oil gears. Be sure to add oil to the specified position (position according to the schematic diagram) before use, and replace it regularly.
b. Oil change interval
When the new reducer is used for the first time, it must be replaced with new oil after a running-in period of 7 to 14 days (150 to 300 hours).The oil must be replaced for the second time after 3 months of use.In the subsequent use process, and regularly check the oil quality, it is necessary to replace the deteriorated oil that contains impurities, pollution, or has been decomposed or aging at any time.Under normal circumstances, the long-term continuous working reducer can be replaced once every 6 to 8 months, and the reducer that works less than 8 hours a day can be replaced once every 10 to 12 months.
c. Oil
The new oil to be replaced must be the same brand number as the original oil used, and different brands and different types of oil products should not be mixed.
Before injecting new oil, heat the same type of oil as the one used during operation, and then use it to clean the gears.
2. Lubrication method
The reducer is generally lubricated by an oil tank and cooled naturally.
When the working balance temperature of the reducer exceeds 900C or the carrying power exceeds the thermal power PG1, circulating oil lubrication can be used, or oil circuit lubrication with cooling pipes can be used.
When the reducer is started after continuous shutdown for more than 24 hours, the gears and bearings should be fully lubricated before they can run with load.
3. Bearing lubrication
For the lubrication of rolling bearings in the reducer, two types of lubricants are often used: lubricating oil and grease.
When selecting lubricating oil, factors such as bearing load, speed, temperature and working environment should be considered.The higher the load of the bearing and the higher the temperature, the higher the viscosity of the lubricating oil used.When the bearing load is small, the temperature is low, and the speed is high, the lubricating oil with low viscosity can be used.
Too much or too little lubricating oil in the bearing will cause the bearing to overheat.When the bearing speed n=1500r/min, the oil level should be lower.
在轴承转动座圈圆周速度不大于4-5m/h，可采用润滑脂润滑。采用润滑脂润滑时，轴承中润滑脂装入量可占轴承室空间的1/3-1/2.
The lubrication method of the rolling bearing in the reducer can directly use the lubricating oil in the oil sump of the reducer. At this time, the lubricating oil in the oil sump of the reducer must be introduced into the bearing.
4. Maintenance and maintenance
4.1 Spare parts manufacturing
The reducer should be checked and repaired regularly.If scratches, bonding and significant wear are found, effective measures must be taken.Spare parts must be manufactured according to standards, and updated spare parts must undergo running-in and load test before they can be officially used.
4.2 Transmission inspection
The reducer should be checked and repaired regularly.If scratches, bonding and significant wear are found, effective measures must be taken.Spare parts must be manufactured according to standards, and updated spare parts must undergo running-in and load test before they can be officially used.
4.3 Oil volume and oil temperature
Check the tightness of the bolts and the amount of oil frequently.The oil level of the reducer is lower than the lower scale line of the vernier scale, and oil should be added in time.Circulating oil lubrication should pay attention to elegant changes. When the oil pressure is significantly reduced, the oil filter should be checked and cleaned.
4.4 Thermal inspection
In order to make the reducer easy to dissipate heat, its outer surface should be kept clean, and the air vents should not be blocked.If the temperature of the cabinet is too high, check whether the oil level is too high, the surrounding heat dissipation conditions are not good, the oil quality is aging, or the amount of cooling water is not enough, the cooling effect of the cooling coil is not good, etc.
4.5 Oil leak inspection
If oil leakage is found in the high-speed shaft, check whether the oil level is too high.If the shaft seal leaks oil due to aging or wear, proper grease can be injected through the grease nozzle on the cover. If the oil leak is serious, the user should replace the oil seal by himself.
Important note: After the reducer has been running for 8 hours, the small area of the soaking oil near the seal is non-penetrating, the extended base of the soaking oil area is oil-seeding, and there is oil leakage on the foundation
4.6 Safety protection
The rotating part of the reducer leakage should be provided with a protective cover, and it should be grounded when it is connected to the motor or other electrical equipment
Important note: Do not remove the trial lens cover during the operation of the reducer to avoid personal injury caused by splashing of high-temperature gear oil.
4.7 Oil change
In normal operation, due to the continuous operation of the surface, metal fines inevitably enter the engine oil.These dirt will shorten the life of the bearing, leading to the early scrapping of the gear unit, so it is necessary to resort to frequent oil replacement for maintenance.
4.8 System management
The user should have reasonable use and maintenance rules and regulations, and carefully record the operation of the reducer and the problems found during the inspection.
Important note: If the user is not familiar with the installation and use of the reducer, but it is necessary to disassemble the host equipment or reducer due to maintenance, please notify our company for technical support or get our company's consent.If the reducer or other equipment is damaged due to abnormal use due to the user's private assembly and disassembly, the responsibility of the paint shall be borne by the user.
