How to prevent oil leakage in KA67 hollow shaft bevel gear reducer

For the oil leakage problem of KA67 hollow shaft bevel gear reducer, it can be prevented from the following aspects:

1. Improve the breathable cap and inspection hole cover: The pressure inside the reducer is greater than the external atmospheric pressure, which is the main cause of oil leakage.Oil leaks can be prevented if you try to balance the internal and external pressures.To this end, the oil cup exhaust cap can be made, the original thin inspection hole cover plate is changed to 6mm thick, and the oil cup exhaust cap is welded to the cover plate. The diameter of the vent hole is 6mm. The exhaust is convenient and the pressure is balanced. From the oil cup oiling.There is no need to open the inspection hole cover to avoid oil leakage.

2. Keep the oil level appropriate: Crane reduction gearboxes are usually lubricated by immersing the large gears in an oil pool.The depth of the gear immersed in the oil should not exceed one tooth height, otherwise the oil will be violently agitated and the oil temperature will increase, which will accelerate leakage.In addition, mechanical efficiency will be reduced due to increased oil resistance.Therefore, the amount of oil must be appropriate. You cannot add less, but you must not add more.

3. Improve the shaft head sealing ring: Set an oil seal ring on the shaft head, mill an annular oil return groove on the middle face of the machine base, and set a semicircular ring on the inner wall of the upper cover on the top of the shaft head to prevent oil splashing on the machine cover. Smoothly flows into the oil pool of the machine base.

4. Leak plugging: Mainly take measures at the center parting surface and shaft head seal, select appropriate sealing materials and components, and plug the gaps.

5. Change lubricating materials: The reducer is lubricated with thin oil. Due to the strong penetration ability of thin oil, oil leakage is prone to occur.If thin oil lubrication is changed to solid lubricating material lubrication, the lubricating oil in the machine will not easily spill out, which can effectively prevent oil leakage.

The above measures can effectively prevent the oil leakage problem of the KA67 hollow shaft bevel gear reducer.At the same time, it is also necessary to pay attention to the working environment and working conditions of the reducer, strengthen the training and management of equipment operators, and improve their operation and maintenance skills.If you encounter oil leakage problems, you should contact professional technicians or manufacturers for repair and maintenance in time.
