Regularly Lubricate the Toothed Gear of Double Teeth Roller Crusher

Double teeth roller crusher has two manners of working: One is open gear transmission; another is closed gear transmission. The gear transmission of double teeth roller crusher is one of the most important and the most widely used drive mode among the numerous mechanical transmission ways. In the daily use, many factors may cause damages to the double teeth roller crusher, so we must have a regular inspection and maintenance on the toothed gear. Next are the matters needing attention during the lubrication of the toothed gear.

First, the temperature. When the temperature drops, the lubricating oil will thicken; otherwise, it will become thin. So under low temperature, we should choose the low-viscosity lubricating oil; conversely, the high-viscosity lubricating oil, in order to prevent the dry friction between metals.

2. The load. The high-viscosity oil is more resistant to heavy burden than the thin oil. So when under a low load, the double teeth roller crusher needs low-viscosity lubricating oil; when under a high load, it needs high-viscosity lubricating oil.

3. The speed. The faster the sliding or rotating, the shorter the time to squeeze lubricant into the gear. In the meanwhile, lubricating oil is easier to become agglomerated and thick under the high-speed operation. So thick oil should be used at low speed and thin oil at high speed.

4. The impact load. For example the rhythms of the engine. Equipment needs thicker oil to prevent the oil film shattering instantly and causing boundary lubrication. On this occasion, it needs a kind of lubricating oil containing ep additives.

5. When the double teeth roller crusher uses straight teeth, helical teeth, herringbone tooth and umbrella tooth, it can generate effective oil film, thus alleviating the immediate contact between the meshing gear teeth. While for the unequal shaft driving device like worm gear, worm and hypoid gear, it often produces boundary lubrication largely.
