With fine bearing is what needs attention to high speed precision bearing use life had a lot to do with the installation, should pay attention to the following: 1.
Bearing installation should be clean, clean the room suspended, bearing through careful selection, bearing with baffle through grinding, insisted on inside and outside the circle circle under the condition of high insulation, baffle parallelism should be controlled below 1 um.
2.
Bearing should be cleaned before installed and when cleaning inner ring ramp up, flexible hand induction, no stagnation, air-dried, into the designated amount of oil, if oil mist lubricating oil should be in a small amount of oil mist;
3.
Bearing installation should use special tools, average stress, it is strictly prohibited to knock;
4.
High temperature bearing deposit should be clean and drafty, non-corrosive gas, are no more than 65% relative humidity, long-term storage should be rust on schedule.
To improve precision bearing with the theory of precision when installation, must not make precision bearing deformation measurement method and measurement tools, the precision bearing surface of the inner hole and cylindrical coordinate dimensions to suspend the theory of precision measurement, inner and outer diameters can be related to the measurement of all items shall be measured, and make a comprehensive analysis of measured data, based on this, according to the precision for shaft and hole the size of the precision bearing installation site.
In the theory of measurement for shaft and hole of the corresponding size and geometry shape, to be the same with measurement precision bearing temperature under the condition of suspension.
In order to guarantee a higher cooperate effect theory, shaft and the surface of the hole with the precision bearing, the roughness should be small as possible.
In the measurement, the above should be on the outer circle and inner hole of precision bearing, as well as the shaft and hole corresponding to the surface, near the sides of the assembly chamfering can make tendency in the direction of maximum Ming for two set of logo, so that the theory of assembly, match on both sides of the largest tend to aim at the same position, so that after the assembly, the tendency of both sides to partially offset.
To make directional signs, the purpose of the two groups is the tendency of compensation can comprehensive thinking, even if the rotation accuracy of supporting their progress, and between the two bearing seat hole and shaft neck on both ends of partially offset alignment error.
To cooperate with the surface to surface strengthening measures, such as sand blasting treatment, with a slightly larger diameter of column precision plug plug a hole, etc. , are all conducive to progress with precision.
The previous: the outer spherical bearing maintenance experience next time: reveal 0 ~ 9 kind of what kind of bearing noise is small
