What are the precautions for the spindle bearing grease installation?

Bearing is a kind of is very important in modern mechanical equipment parts, main shaft bearing installation of the whole mechanical operation plays an important role. During the installation process, choose the appropriate also is helpful for prolonging the life of the spindle bearing grease, let's come to know about the spindle bearing installation notice what are the grease. 1, good lubricity to keep between shaft and bearing contact surface have a uniform oil film, and in the main shaft impact load of oil film start or stop the movement also not dent, keep good lubrication performance, play to reduce friction and friction heat, lowering the temperature rise of the main shaft, ensure the machining accuracy, oil has good lubricity. 2, good rust resistance due to the oil in the working process of the spindle lubrication system will inevitably mixed with condensed water or machine cooling fluid in the air, so the oil has good rustproof, especially in hot and humid climate in the south area, especially pay attention to the main shaft bearing anti-rust. 3, good oxidation resistance when using circulation lubrication method, main shaft bearing oil use for a long time and the same, will not produce for swimming and clogging oil mud and the bearing clearance, small corrosion effect, so the oil has good resistance to oxidation stability, China's industry standard oil oxidation stability index for 1000 h ( ( GB / T, 12581) 。 4, suitable strength and good temperature characteristics to machine the main uranium for use temperature is not too high and make the machine tool thermal deformation, affect the machining accuracy or make poor lubrication bearing, should according to the structure of the spindle bearing, speed and bearing clearance to choose a suitable doneness of lubricating oil Wells for oil has good temperature characteristics show concern and prevent a spindle working temperature and environmental temperature change is big, teaching degree changes which affect its lubrication performance. 5, installation site clean installation site should be as clean as possible, avoid the pollution of bearing or the entry of foreign body, pollutants on the running and service life of bearing has great impact. Check the bearing hole and shaft with the geometric accuracy, dimensional accuracy, and cleanliness. 6 bearing inner ring, installation Angle and the spindle assembly with the directional assembly method or Angle matching method, which is artificially control the direction of the radial runout of assembly errors, reduce the error offset each other instead of accumulation; After bearing pressure into the bearing should be flexible rotation without block feeling; After the installation is complete, check whether the precision bearing system is working properly. That is to tell you about the spindle bearing installation considerations, grease grease on the service life of main shaft bearing plays a crucial role, in the process of installation of the main shaft bearing need to be noticed.
