At high speed rotation, the choice of the lubrication method of the bearing is also the cause. Bearings have been fully certified in almost all possible areas and have always played a very important role. The bearing temperature runs to rise, if there is no different, usually 1 ~ 2 hours later. However, with oil holes, the temperature of the outer ring temperature is more correct. If the bearing or device is poor, the bearing temperature will rebound sharply and exhibit a different high temperature.
Selectively place the free end bearing in the position where the deviation may be canceled, the support position after the bearing housing is mounted, and the roundness deviation between each other and the coaxial degree deviation may be canceled as much as possible.
The front bearing of the fixed end is thoroughly cleaned with clean cleaning kerosene on the shaft. However, due to the deformation of the mating or the holder, the preload also has a possible possible possible). The integrated calibration of the installation accuracy will be loaded into the spindle into the spindle.
Improve a method of bearing precision a factory trial precision Clutch Release Bearing factory instrument, the spindle 6202 / p2 bearing is still unable to meet the requirements, then add the thick journal and make the roller to replace the inner ring, and put steel.
The ball is tested, and the size of each three capsules in size is separated by a size of 120 °, and the surface of the steel ball is separated.02 ~ 0.05 μm, and the three-tightened head is inserted on the surface of the journal, and the shaft is measured on the surface of the journal, and the error is measured below 10 μm; The head contacts the inner surface of the rear seat, rotates the shaft to measure the coaxial degree of the housing front and rear seat holes.
