What are the differences in maintenance methods for K series hard tooth surface gear reducers of different models

The maintenance methods for different models of K-series reducers are generally similar, but due to factors such as specifications, structure, and usage scenarios, 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 for some models used in special working conditions, such as in low-temperature environments (-10 ℃ to 15 ℃), when the output speed is above 100 revolutions per minute, it may be necessary to use No. 68 gear oil; When the speed is below 100 revolutions per minute, it is recommended to use 100 grit gear oil 3. For low-speed high load and high-speed high load working conditions, it may be necessary to use gear oil with high viscosity and good extreme pressure and anti-wear properties, such as synthetic oil. Some small K-series reducers may also use semi fluid grease for intermittent operation.

Oil level inspection frequency: Usually, the inspection frequency of new reducers is higher during the initial operation, and the interval can be appropriately extended afterwards. However, for large or high load K series gearbox models, due to their faster consumption and contamination of lubricating oil, it is necessary to check the oil level more frequently, possibly every 100-150 hours of operation; For small and lightly loaded models, the inspection interval can be appropriately extended to every 200-300 hours of operation.

Oil change cycle: Generally, new K series reducers need to change the lubricating oil after 300 hours of operation, and then change it every 3000 hours or so thereafter. However, for models that work in harsh environments such as high temperatures and high dust, or operate continuously under high loads, the oil change cycle may need to be shortened to 2000-2500 hours; For models used in cleaner, stable load, and shorter operating environments, the oil change cycle can be extended to 3500-4000 hours.

Heat dissipation requirements: K series reducers generally use oil pool splash lubrication for natural cooling. But for models with high power and long-term continuous operation, when the thermal balance power is insufficient, heat dissipation measures may need to be taken, such as installing cooling pipes or using a circulating cooling lubrication system; For small, intermittent models, natural cooling is usually sufficient to meet the heat dissipation needs, as long as the outer surface of the gearbox is kept clean and the ventilation plug is not blocked.

Focus of inspection items: For K-series gearbox models with high torque and high load, it is important to inspect the wear of gears and bearings, as they bear greater loads and are more prone to wear, cracks, and other issues; For some high-speed operating models, in addition to checking the gears and bearings, attention should also be paid to the condition of the seals, as high-speed operation may make the seals more prone to aging and leakage. In addition, for reducers installed in environments with high vibration, it is necessary to regularly check whether the bolts at each connecting part are loose.

The difference in maintenance methods for different models of K series reducers mainly depends on factors such as their operating conditions, load size, and speed. In actual maintenance, a suitable maintenance plan should be developed based on the specific model and user manual of the gearbox.
