Viscosity is an important physicochemical indicator of WPEDO60-100,WPEDO70-120,WPEDO80-135,WPEDO80-147,WPEDO100-155 gear oil. Choosing the correct viscosity of gear oil can reduce the internal friction of the lubricating oil, thereby reducing the wear, transmission noise, vibration, and other factors on the surface of the reducer gear. So, what is the appropriate viscosity of lubricating oil? This issue still troubles many users, let me introduce it to you!
1. The viscosity of the lubricating oil for the gearbox is mainly achieved through the use of base oil and viscosity index improvers. Among them, the viscosity of the base oil is related to its molecular structure and molecular weight. The higher the average molecular weight, the higher the viscosity of the oil.
2. A good adhesive should have high thickening ability, good shear stability, good low-temperature performance, and thermal oxidation stability.
3. For lubricating oils with the same viscosity grade, if non refined base oils and poor viscosity agents are used, although they can reach a certain viscosity standard through blending, their viscosity temperature performance, shear stability, and other properties are poor, and they cannot reach the expected service life.
In actual production, we can choose the viscosity of the lubricating oil for the reducer according to the above method. For low-speed and heavy-duty reducers, we should choose a better lubricating oil and try to avoid using non refined base oil or poor adhesive, because its base oil and adhesive are both better. The higher the viscosity of the gear oil, the stronger the protective ability of the textile tooth surface from various damages, and the less mechanical wear.
