Maintain good low noise Mosaic solid lubricated bearing key method

Installed in institutions, Mosaic solid lubricated bearing parts allowed to have a certain temperature, when the hand touch body shell, should not feel hot as normal, conversely indicates that bearing temperature is too high. The cause of the high bearing temperature are: lubricating oil quality does not conform to the requirements or metamorphism, lubricating oil viscosity is too high; The assemble tight ( Inadequate clearance) ; Plane bearing assembly too tight; Bearing race in internal rotation shaft or housing; Too much load; Bearing cage or rolling body fracture, etc. Mosaic solid lubricated bearing allows running noise slightly in the work, if you have any abnormal noise or excessive noise or sound, suggests that the bearing failure. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to the wear and tear, damage to the bearings and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Bearing wear loose after kuang, maintains a looseness damage, also can produce sound. ( 1) Bearings with low noise requirements in the national standards of production of bearings, ball bearings from inner diameter phi 2. 5 mm to phi 60 mm have several varieties with Zl, Z2 and Z3 three suffixes, corresponding to three different types of low noise, and roller bearing from N309 type to type N322 eight models have made according to standard low noise. These Mosaic solid lubricated bearing can apply to other machines with low noise requirements, and the price is cheap, as on the type and size can be request, try to use the two types of low-noise bearings. ( 2) Using relatively small bearing noise when not using the above two types of low noise bearings, bearing can use noise is relatively small. Specific comparison basis is as follows: 1) The noise of the ball bearing is lower than that of the roller bearing, relatively less sliding bearing ( Friction) More noise than the relative sliding bearing is low; 2) Using solid cage bearing noise is relatively than using punch retainers Mosaic solid lubrication bearing is low; Using the plastic cage bearing noise than using the above two cage bearing are low; The count more, the outer ring thickness, noise is small, 3) High precision bearing, especially of the higher precision roller used Mosaic solid lubrication bearing, its noise than the low precision of bearing noise is relatively small, 4) Small bearing noise than the big bearing noise is relatively small.
