The faulty appearance of the rolling bearing usually shows two kinds; one is that the temperature of the bearing device is too high; the other is that there is noise in the bearing work.
1. When the
bearing temperature <br> organization; promised parts bearing means have a certain temperature; tissue when stroking a housing; should not be difficult to feel normal; otherwise indicated bearing temperature.
The reasons for the excessive bearing temperature are: the quality of the smooth oil does not meet the demand or the change; the viscosity of the smooth oil is too high, the structure is too tightly installed (the gap is lacking), the bearing is installed too tightly, the bearing race is changed on the shaft or the shell, and the load is over. Large, bearing cage or rollover fragmentation.
2. <br> rolling bearings
bearing noise at work has promised to work fine sound; if the noise is too large or unusual noise or crash; faulty bearing the mark.
The cause of the noise of the rolling bearing is more complicated; the first is the wear of the inner and outer rings of the bearing. Because of this wear; the cooperation between the bearing and the housing, the bearing and the shaft is destroyed; the axis is deviated from the correct orientation; Abnormal noise occurs during high-speed movement. When the bearing is exhausted; its appearance metal falls off; it will also increase the radial gap of the bearing and cause abnormal noise. In addition, the bearing is smooth and lacking; the dry conflict is formed; and the bearing is broken, etc. After the bearing wears loose, the cage is loose and damaged; abnormal noise will also occur.
