The points for attention during the loading precision bearing

The points for attention during the loading precision bearing high-speed fine bearing use life and device has much to do, should pay attention to the following: 1. Bearing assembly should be clean, clean the room stopped, 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 assembly should be washed clean before, when cleaning inner ring ramp up, hands are sensitive, no stagnation, air-dried, into the designated amount of fat, in the case of a mist smooth should add a small amount of oil mist; 3. Bearing assembly should use special tools, force uniform, do not 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 the practice of the fine bearing device with precision, necessary applications do not make fine bearing deformation measurement methods and measurement tools, the precision bearing inner hole and cylindrical cooperate to stop the practice of fine appearance size measurement, inner and outer diameters can be related to the measurement of all items shall be measured, and the measured data to make a comprehensive analysis, based on this, according to fine match for shaft and hole the size of the fine bearing assembly parts. In practical measurement by shaft with corresponding size and geometry shape of hole, is to be the same with measurement precision bearing temperature stops. In order to guarantee a higher effect, the practice of shaft and housing with fine bearing hole appearance, the roughness should be small as possible. In the measurement, the above should be in fine bearing outer circle and inner hole, as well as the shaft and hole corresponding to their appearance, near the sides of the assembly chamfering, respectively, can make clear the direction of the maximum deflection in two group mark, in order to practice assembly, make suitable maximum deflection on the same position of the two parties, so that after the assembly, the two sides to local bias offset.
