1. Permeability:
Because some areas that need to be lubricated are relatively small, the lubricating oil needs to have good penetrating properties when lubricating, so that some relatively dense areas can be better processed.
2. Adhesion:
Sometimes the device rotates in a high-speed state, so the lubricating oil on the sprocket may be thrown out under the action of inertia, and the lubricating oil will also be under gravity at low speeds. It drops under the action, which will not only cause a lot of waste of lubricating oil, but also pollute the equipment and the surrounding environment. Therefore, when choosing lubricating oil, it must be used for good adhesion, which can be more firmly attached to the friction. The surface will not easily leave the device surface due to other factors.
3. Lubricity:
One of the main functions of lubricating oil is to carry out lubrication, but when the device is used, there will be some differences due to the function and so on, so the requirements for its lubrication performance are also different, such as in some cases of heavy load and impact. The requirements for extreme pressure and abrasion resistance are generally higher. Therefore, when choosing lubricants, we pay more attention to this.
4. Oxidation stability:
Because some devices work in a bare environment, the lubricant is also required to have good oxidation stability.
