What are the advantages of gear oil lubrication bearings? In car maintenance, some owners will use butter lubrication when maintenance shaft, it would accelerate the early damage of the cross shaft of the rolling bearing for lubricating cardan shaft bearings is a common nozzle, because the viscosity of butter with butter, when the gun from the nozzle to the cardan shaft roller bearing inner cavity filled with butter, butter into the narrow cavity oil passage resistance increase, butter pressure open top valve nozzle on the other side of the overflow. This phenomenon is easily mistaken for the topping up of butter.
In fact between the butter did not enter the needle, remove in maintenance, with mandatory methods butter on needle roller and shaft neck surface may play a lubricating function, so the selection of gear oil, the effect will be better, this is because:
1, calcium grease is made by oil and calcium soap mixed, in use due to lubrication oil deterioration and evaporation, make grease into calcium soap hard, calcium soap itself will not play lubrication, but also hindered the needle rolling in the shaft neck, plus the cardan shaft ten and no exhaust oil measures, changed grease quality can not be discharged, it is difficult to inject new oil, thus greatly accelerated wear of cardan shaft needle bearing.
2, cardan shaft bearings can only work in place cannot rotate along the steel bowl and the cross shaft rotation, and calcium base grease rolling is very poor, so when the oil film is not immediately after the destruction of oil film forming new.
3, the universal joint in the work to withstand great torque and alternating load, and calcium based grease film tough degree is poor, in the bearing and Journal of the friction surface is difficult to form a good oil film.
In the use of gear oil should pay attention to, should first remove the universal joint, cross shaft, needle roller bearings, after a thorough cleaning, the remaining grease all cleared, put into gear oil immersion 2min~l0min, you can install. In use, should pay attention to, after the car wading, should replace the new oil. Driving 2000km~3500km should replace the new oil. Conditional owners can be equipped with special hydraulic filling equipment, the transmission shaft of the universal joint, cross shaft, needle roller bearings regularly lubricated. |
