After long-term operation of the Shanghai helical gear reducer , it may sometimes be found that the lubricant will "run, run, leak", which affects the normal use of the helical gear reducer. The reason is that the internal oil temperature of the sealed helical gear reducer has increased. With the increase of the air pressure, the viscosity of the lubricating oil decreases, causing the lubricating oil to "run, run, leak" at the gap of the reducer. In response to this situation, we have summarized many solutions, and share them with you below.
1. The ventilator in the helical gear reducer is the easiest place to combine dust and oil. Usually, after a period of operation, the ventilator is blocked. Therefore, the normal ventilation of the ventilator is the key to solving the “running, running, leaking” oil of the reducer. For this reason, the ventilator is changed to a downward-pointing curved pipe with foam (or sea brocade), and the foam can be changed once a month or so. Only when the ventilator is not blocked can the pressure inside the box be balanced with the atmospheric pressure. Obviously, this is the key issue to prevent "run, run, leak" oil.
2. Seal the felt in the transparent cover. Before installation, soak it in heated liquid grease for 1 to 2 hours before installing and using it. The sealing effect is quite good.
3. At the split plane of the machine base, use a narrow gauge (or milling) to machine the oil return groove, so that the oil to be spilled will return to the box.
4. Replace the bearing penetrating cover of the helical gear reducer. On the newly manufactured bearing penetrating cover, 2 to 3 annular grooves are mainly processed, and the 6 oil holes with 6 oil holes distributed uniformly must be paid attention. The oil hole is at the bottom (that is, the oil return hole is tangent to the annular groove), which makes the oil return effect good.
5. Add "water glass" to the joint surface of the upper and lower boxes. Although this is a traditional method, it is often overlooked.
In fact, the viscosity of lubricating oil is also very important for Shanghai helical gear reducer. In addition to paying attention to the above five points, it is necessary to choose a suitable lubricating oil in winter and summer. "Run, run, leak" problems.
