summary:
NGW-L type vertical planetary gear reducer is mainly suitable for mixing transmission devices, lifting, metallurgy, transportation, and lightweight general mechanical equipment. Its applicable conditions are:
The high-speed shaft speed shall not exceed 1500r/min;
The gear line speed does not exceed 15m/s;
The working environment temperature is -40~500 ℃;
It can operate in both directions

Example of Marking:

main features

1. Lightweight and compact, under the same conditions, it weighs more than half of a regular involute cylindrical gear reducer and reduces its volume by 1/2-1/3

2. High transmission efficiency Single level η=0.97-0.98; The two poles have an η of 0.94-0.96.

3. Strong adaptability and a wide range of transmitted power.

4. The main components are treated with high-quality alloy steel carburizing, quenching, and nitriding. Planetary gear reducers have balanced operation, low noise, and long service life.

Lubrication of reducer

1. The NGW-L planetary gear reducer adopts oil pool lubrication and lubrication. When the ambient temperature is high, the power is large, the speed is high, and the reducer is working continuously, and the heat dissipation of the reducer itself is insufficient, cyclic lubrication is used.

2. When the working environment temperature of the reducer is low, measures should be taken to ensure that the oil temperature is above 10 ℃.

3. The amount of oil for lubrication in the oil tank should be at the height specified by the oil gauge.

4. The lubricating oil used is 90-120 grade extreme pressure industrial gear oil.

Installation, use and maintenance

1. The output shaft of the reducer should be coaxial with the axis of the connecting part.

2. The installed reducer must undergo a load test before formal use. Before the load test, run the vehicle for 2 hours without load and 4 hours at full load. The maximum oil temperature shall not exceed 80 ℃, and the temperature rise shall not exceed 45 ℃. The reducer runs smoothly without any impact, vibration, or oil leakage.

3. The reducer with new or newly replaced gears should be replaced with new oil after running for 10-15 days for the first time. Under normal circumstances, for reducers that work continuously 24 hours a day, the oil should be replaced every three months. For reducers that work for no more than 10 hours a day, the oil should be replaced every six months.

4. During operation, if the oil temperature significantly increases and exceeds 80 ℃, the quality of the oil deteriorates, and abnormal noise is produced by rolling soil, the use should be stopped, the cause checked, and the fault eliminated before use.
