How to choose lubricating oil for YTC series gear reducers

With the continuous advancement of industrial technology and the constant upgrading of equipment, YTC series gear reducers, as key equipment in many industrial fields, have attracted increasing attention to the selection of lubricating oil. The correct selection of lubricating oil can not only significantly improve the operating efficiency of the gearbox, but also effectively extend its service life and reduce the maintenance cost of the enterprise. So, how should the lubricating oil for YTC series gear reducers be selected?

1. Consider working conditions

Working environment: YTC series gear reducers are widely used in various industrial fields such as mining, metallurgy, sugar production, papermaking, chemical industry, rubber, etc. The working environment in these fields is different, and some may contain dust, corrosive gases, etc. Therefore, when choosing lubricants, it is necessary to consider their corrosion resistance, wear resistance, and other properties.
Load situation: YTC series gear reducers of different models bear different loads. For gearboxes with high loads, lubricating oil with stronger load-bearing capacity, such as extreme pressure gear oil, should be selected to provide sufficient lubrication and protection.

Speed requirement: The speed of the gearbox is also an important factor in selecting lubricating oil. High speed gears require the selection of lubricating oil with low viscosity and good fluidity to ensure good lubrication effect; For low-speed gears, lubricating oil with high viscosity and good wear resistance can be selected.

2. Pay attention to the performance of lubricating oil

Viscosity: Viscosity is one of the important performance indicators of lubricating oil. Choosing the appropriate viscosity can ensure that the lubricating oil forms a stable oil film between the gears, reducing friction and wear. Generally speaking, the appropriate viscosity grade can be selected based on the speed and load conditions of the gearbox.
Extreme pressure performance: Extreme pressure performance refers to the ability of lubricating oil to prevent direct contact and wear of metal surfaces under high pressure. For YTC series gear reducers with high loads, lubricating oil with good extreme pressure performance should be selected.
Wear resistance performance: Wear resistance performance is the key to lubricating oil protecting gear surfaces and extending equipment service life. High quality lubricating oil should have good wear resistance, which can reduce wear and friction between gears.
Clean dispersion performance: Clean dispersion performance refers to the ability of lubricating oil to suspend carbon deposits, sludge, and other sediments inside the engine and flow into the oil pan with the lubricating oil. Choosing lubricating oil with good cleaning and dispersing properties can maintain the cleanliness and good operation of the gearbox.

Antioxidant performance and thermal stability: Lubricating oil is prone to oxidation and deterioration in high temperature environments, which affects its lubrication performance. Therefore, it is necessary to choose lubricating oil with good antioxidant performance and thermal stability to ensure that it can maintain good lubrication effect at high temperatures.

3. Recommended lubricant types

For YTC series gear reducers with small base numbers, such as cycloidal reducers, lubricating grease such as molybdenum disulfide 2 or ZL-2 lithium based grease is usually used for lubrication. These lubricating greases have good wear resistance and extreme pressure performance, which can meet the lubrication needs of small reducers.

For YTC series gear reducers with large base numbers, such as spiral elevators lubricated with oil baths, industrial extreme pressure gear oil is generally used for lubrication. When selecting, the appropriate viscosity grade and extreme pressure performance can be chosen based on the ambient temperature and load conditions. For example, when the ambient temperature is -10~5 ℃, 68 extreme pressure gear oil (N68 according to Chinese standards) can be selected.

4. Precautions

Do not change the lubrication scheme arbitrarily: if the original oil lubrication is changed to grease lubrication, it may result in inadequate lubrication or inability to dissipate heat, thereby affecting the performance and service life of the gearbox.
Regularly changing lubricating oil: According to the usage of the gearbox and the manufacturer's recommendations, regularly changing lubricating oil is an important measure to maintain its good operation. Generally speaking, after the first 200 hours of operation, the gearbox should have its lubricating oil replaced for the first time, and then regularly replaced according to the frequency of use and load conditions.
Choose a reputable brand of lubricant: There are numerous lubricant brands on the market with varying quality. It is recommended to choose a reputable and reputable brand of lubricating oil to ensure its quality and performance.
In summary, selecting the lubricating oil suitable for YTC series gear reducers requires comprehensive consideration of multiple factors. By selecting and using lubricating oil reasonably, the good operation of the gearbox can be ensured and its service life can be extended.
