The use of non-standard bearing note grease performance requirements analysis of the indicators

Using the matters needing attention of non-standard bearing grease performance index analysis of the source: bearing | last updated: - 2020 09 - 24 the use of non-standard bearing note 1. Normal use after one year should replace 2 # spindle oil and coarse fine filter. 2. Normal using pump station to make up for the oil must be 3 layer filter for silk cloth. 3. When spindle pulley, wheel loading and unloading must be under the conditions of pumping station operation. The spindle under the conditions of static pressure oil float. So don't damage the spindle and dynamic pressure bearing. 4. Grinding wheel spindle survey 'before the pump pressure and the grinding head can static pressure in a standard size. 5. Equipment mainly; Must be stopped first grinding head motor; After waiting for grinding wheel stopped; To turn off the pump station; Or simple grinding head injury. 6. In the pump station of any components. Must first removing the high pressure oil inlet hose connection; After replacing the parts; Rear oil loop of 15 ∽ 20 minutes into the tubing can be connected to grinding head; Thus ensure the into the grinding head spindle oil is super clean spindle oil through fine filtering. Doing so can extend the use of dynamic pressure spindle longevity. Non-standard bearing grease performance index analysis of the bearing grease performance indicators of a lot of, mainly colloidal stability ( Oil) , mechanical stability, 100000 shear test, lengthen working cone into the degree of value) And oxidation stability, the three indicators comprehensive results, is bearing life. Running in the bearing grease of mechanical force damage, make the fiber of thickener rupture shorter, reduce the ability to maintain the structure of the grease, the consistency of change, if consistency change very assembly from the working surface erosion phenomenon, at the same time in the operation of grease will be influenced by temperature, base oil can produce evaporation and reduce or part of the base oil as lipid gel break points loss to reduce fat oil content of the oil, also has the potential to produce the oxidation. Non-standard bearing grease performance indicators many, therefore, for bearing grease, if working within fat base oil content lower than 60% When 70% ( The base oil loss due to evaporation or points of oil - 30% 40%) Lose lubrication ability will be reduced and even cause the failure of bearing operation, at the same time of consistency and oxidation of fat and bad work more will affect the running of the bearing
