RV Worm Gearbox Add Oil Volume Chart2022-04-19T13:31:14+08:00

The RV worm gearbox use and replacement of lubricating oil
1. When using or replacing the RV worm gearbox for the first time, replace the lubricating oil after running for 150-400 hours, and the subsequent oil change period ≤ 4000 hours;
2. Check the quantity and quality of the oil regularly, keep enough lubricating oil, and replace the oil mixed with impurities or deteriorated in time;
3. The amount of oil injection must be in accordance with the table requirements. It is forbidden to mix oils of different grades, and it is allowed to be mixed for the same grade oil but different viscosities.
4. The RV worm gearbox working ambient temperature is -40°C~+40°C. When the ambient temperature is lower than 0°C, the lubrication must be heated to above 0°C before starting running or using the lubricating oil with a low freezing point.
5. Table 1 for RV worm gearbox add oil volume chart, and table 2 is Types of lubricating oil used in gearbox.

The reason for the industrial geabrox oil temperature rise2021-08-03T21:58:05+08:00

Question:
Please briefly analyze the reason for the industrial geabrox oil temperature rise

Answer:
a. The gearbox’s lubricating oil is unqualified or the gearbox has been used for too long.
b. Too much lubricating oil is not conducive to the heat dissipation of the mechanism in the gearbox.
c. The machine is damaged. Mechanical damage includes severe pitting of gears, broken teeth, bearing cages, inner and outer rings, ball damage, and bearing embedment. dead or severe shaft deformation;
d. The outside of the gearbox is covered by debris or dust. When things are piled around the gear reducer or the surface of the gearbox’s body has not been cleaned for a long time, it may be due to the coverage of sundries or dust causes incomplete heat dissipation of the gear reducer, which causes the oil temperature to rise;
e. The cooling device is blocked or fails. The cooling device is placed in a dusty workshop like the gear reducer. when the internal pipeline causes the cooling device to be blocked or the cooling device is broken, it will cause the industrial gearbox oil temperature to rise.
