The following is a detailed analysis of the causes and treatment methods for the oil leakage problem of the reducer of the low space electric hoist crane:

Reasons for oil leakage

Sealing failure:

The sealing ring or gasket of the gearbox may fail due to aging, wear, or long-term deformation under stress, resulting in oil leakage.

Excessive work pressure:

If the internal pressure of the reducer is too high and the sealing performance is insufficient, the oil may leak out from the seal under pressure.

Improper assembly:

During the assembly process of the gearbox, if the various components are not tightly connected, it may lead to oil leakage. For example, improper installation of seals or inadequate tightening force.

High working temperature:

Running the gearbox in a high-temperature environment can cause a decrease in the viscosity of the lubricating oil, increase the fluidity of the oil, and potentially lead to oil leakage.

Oil level too high:

The oil level inside the gearbox is too high, and when the oil fluctuates or the machine is running, excess oil may overflow from poorly sealed areas.

processing method

Check and replace the seals:

Regularly inspect the sealing rings and gaskets of the gearbox, and replace them promptly if aging, cracking, or wear is found.

Use high-quality sealing materials to improve sealing effectiveness and reduce the likelihood of oil leakage.

Adjusting work pressure:

Regularly check the internal pressure of the gearbox to ensure it is within a reasonable range.

If the pressure is found to be too high, consider replacing the exhaust device or adding a pressure regulation system during design to maintain normal internal gas emissions.

Correct assembly:

During the assembly process of the gearbox, it is necessary to follow the requirements of the product manual.

Ensure that the fastening strength at each connection meets the standard, especially when installing seals, avoid excessive compression or uneven force.

Control working temperature:

Ensure that the gearbox operates within a reasonable temperature range to avoid overheating.

Good heat dissipation performance can be maintained by installing cooling devices such as radiators and fans, or by adopting excellent heat dissipation structures during design.

Adjust the oil level:

Adjust the oil level inside the gearbox to an appropriate level to avoid oil leakage caused by excessive oil level.

Strengthen maintenance and upkeep:

Regularly maintain the gearbox, including checking the oil level, replacing lubricating oil, cleaning the radiator, etc.

Strengthen training for equipment operators on the operating principles, maintenance, and oil leakage prevention knowledge of reducers, and enhance their awareness and skill level.
