Analysis of Reducer Oil Leakage Causes
1. Increased pressure in the oil tank
In an enclosed reducer, each pair of meshing gears generates friction and heat during operation. According to Boyle's law, as operation time extends, the temperature inside the reducer gradually increases. Since the reducer box volume remains constant, the internal pressure increases accordingly. The lubricating oil is splashed onto the inner walls of the reducer box. Due to oil's strong permeability, under internal pressure, oil will leak from any location where the sealing is not tight.
2. Oil leakage caused by unreasonable reducer structural design
For example, if the reducer is designed without a ventilation hood, the reducer cannot achieve pressure equalization, causing the internal pressure to continuously increase and resulting in oil leakage.
3. Excessive oil quantity
During reducer operation, the oil pool is vigorously agitated, causing lubricating oil to splash everywhere inside the machine. If too much oil is added, large amounts of lubricating oil accumulate at shaft seals, joint surfaces, and other locations, leading to leakage.
4. Improper maintenance technology
During equipment maintenance, inadequate cleaning of contaminants from joint surfaces, improper selection of sealant, reverse installation of sealing components, or failure to replace sealing components in a timely manner can also cause oil leakage.
Reducer Oil Leakage Management
The problem of oil leakage in reducers is a challenge that troubles many manufacturers. Here are several countermeasures from Lashing to address the oil leakage problem:
1. Improve the breather cap and inspection hole cover. Create an oil cup type breather cap and replace the original thin inspection hole cover with a 6mm thick one. Weld the oil cup type breather cap onto the cover, with a ventilation hole diameter of 6mm to facilitate ventilation and achieve pressure equalization. Additionally, oil can be added through the oil cup without opening the inspection hole cover, reducing leakage opportunities.
2. Ensure smooth flow. Create a return oil groove inclined toward the machine interior at the center of the lower bearing shell, while also creating a notch at the straight edge of the end cover, aligned with the return oil groove. This allows excess lubricating oil to flow back to the oil pool through the notch and return oil groove.
3. Improve the shaft seal structure.
(1) Shaft seal improvement for reducers with half-shaft output.
(2) Shaft seal improvement for reducers with full-shaft output.
4. Adopt new sealing materials. For static sealing point leakage in reducers, new sealing materials can be used for plugging.
5. Wiping. After equipment stops operating, wipe oil stains from the shaft.
