What are the differences in maintenance methods for different models of K series gear reducers
The K series reducers include various models such as K, KA, KF, KAF, etc. Different models of K series reducers have similar maintenance methods, but there may be differences in some details, mainly reflected in the following aspects:
Lubricating oil selection: Generally speaking, K series reducers usually use medium extreme pressure gear oil, such as N110-N200, etc. But specific to different models, it may vary due to factors such as transmission power, speed, and working environment temperature. For example, for reducers with an output shaft speed of over 100 revolutions per minute and an ambient temperature between -10 ℃ and 15 ℃, it may be recommended to use No. 68 gear oil; When the output shaft speed is below 100 revolutions per minute, it may be recommended to use 100 gear oil 10. In addition, gearboxes operating under high and low temperature conditions may require the use of extreme pressure gear oils such as VG220, VG320, VG460, etc. Meanwhile, different installation methods may also affect the amount of lubricating oil added. For example, the K37-K187, KF37-KF157, KA37-KA187 and other models of K series reducers have different oil consumption under different installation methods such as M1/M2/M3/M4/M5/M6.
Maintenance cycle: After a running in period of 7-14 days (150-300 hours), the new gearbox generally needs to be replaced with new oil. It must be replaced with new oil for the second time after 3 months of use. In the future use, gearboxes that work continuously for a long time can have their oil replaced every 6-8 months, and gearboxes that work for no more than 8 hours a day can have their oil replaced every 10-12 months. However, for some large or heavy-duty K-series gearbox models, such as K157, K187, etc., due to their high load capacity, it may be necessary to check the oil quality more frequently and shorten the oil change cycle. For small reducers such as K37, K47, etc., the oil change cycle can be appropriately extended when the load is small and the working environment is good, but it is also necessary to regularly check the oil quality.
Inspection of vulnerable parts: The vulnerable parts of the K series reducer mainly include lubricating oil, oil seals, and bearings. The wear of vulnerable components may vary among different models of reducers. For example, in some high-speed and high load models, the wear of bearings and oil seals may be relatively fast and require more frequent inspection and replacement. For gearboxes that are often exposed to harsh working environments such as high temperature, humidity, and dust, the aging and damage of oil seals may be more severe, and it is necessary to inspect and replace them in a timely manner to prevent oil leakage. For some small models, due to their relatively simple structure, component wear may be relatively slow, but regular inspections are also necessary to ensure their normal operation.
