Reasonable selectionElectric forkliftDrive shaft gear oil

(1) Choose gear oil

1. Viscosity grade and selection. The viscosity classification of industrial gear oil is based on the GB3141-82 "Classification of Industrial Smooth Oil Viscosity" standard, which is determined by gear pitch, gear material, and external stress.

2 Quality level selection. The quality level is determined based on the contact stress of the tooth surface,Electric Forklift X SeriesYou can choose according to Table 1. Generally speaking, the quality level should be high or low, and high-end oil can be used in high-end places, and vice versa.

3. Gear oil is used for the drive axle of electric forklifts. Export forklifts use Mobil gear oil (MD Gx-90), which meets the requirements of the American Petroleum Institute API Quality Classification GL-4. It is a multi-purpose gear oil with excellent anti-corrosion and rust prevention capabilities. Suitable for curved gears, manual transmissions, and passengers and trucks used for high-speed driving.

Domestic forklifts use 220 # medium load gear oil (GL-4), which has extremely high pressure resistance and wear resistance on the basis of anti-oxidation and anti rust industrial gear oil. Suitable for gears operating at medium loads. For example, the contact stress of gears is 500-1100N2, and blocked cylindrical gears, helical gears, and herringbone gears are installed.

(2) Precautions for using gear oil

Be careful to avoid mixing impurities with water

Select an oil with an appropriate viscosity grade based on the ambient temperature,Internal Combustion Forklift X SeriesTo ensure smooth requirements under high temperature and high temperature task conditions. For example, our company is located in the north, and the temperature difference between winter and winter is not as large as in the south. The temperature is not too long or too low. Therefore, our company's forklifts use the same grade of gear oil in summer and winter.

3. The oil level should always be reflected in the application. If there is too much oil and the internal pressure is high,Internal Combustion Forklift A SeriesOil leakage, damaged half shaft oil seal, effective braking. If the oil level is too low, the gear bearings will be smooth and the wear of the machine will increase.

It is necessary to promptly reflect the functional objectives and purification status of gear oil. If it exceeds the standard, it must be changed. When changing the oil, please clean the gearbox and inject new oil. The oil level should be appropriate.
