The roller bearing seat is used to support the bearing, the bearing outer ring is fixed to the inner ring outer ring, just turn, remain motionless, always keep consistent with the direction of transmission (such as motor running direction), and keep the balance. Bearing seat is the concept of the assembly of the bearing and the box, easy to use, the benefits of the sample is that there can be a better fit, easy to use, less the cost of the use of manufacturers. Caused by a variety of shapes, usually a box bearing, which can be mounted therein.
Roller bearing seat in the installation will encounter some problems, below to introduce you to the street will often encounter some problems.
1, to choose the size of the installation. General roller bearings can be installed in the space is limited, it is a certain requirement, so that must not be arbitrary use.
2, prohibit arbitrary removal. This may result in parts that are not tightly sealed and can not operate, thereby affecting the service life of roller bearings.
3, the speed and bearing tolerance should also be noted that the roller bearing speed is based on the size, accuracy and other factors to determine, bearing tolerance should also pay attention to, not too much difference.
Some friends in the use of roller bearing seat will encounter roller bearing seat damage, then what factors lead to roller bearing seat damage? Here to introduce you.
1, roller bearing material is not international materials, does not meet international standards;
2, in the roller bearing raceway processing jerry;
3, roller bearing installation process does not meet the standard;
4, roller bearings inside the use of carbon steel ball or ultra-thin retainer, is a fake and shoddy parts
5, roller bearings are not cleaned or the equipment does not have the function of drying, roller bearings without demagnetization, very easy to absorb dust;
6, roller bearing clearance is too small.
After the purchase, how do we check the roller bearings? Here to introduce you.
When we check the bearing will use some sound measuring machine, check the problem by judging the bearing rolling process problems, generally if the bearing has some slight damage can be judged by abnormal sound, can early find the problem. The temperature is always the key for the detection of the bearing problem, then how can a good monitoring of bearing problems? We need to use the bearing oil hole on the outer ring of the bearing temperature measurement, in general, after the beginning of bearing operation, the bearing temperature will slowly rise, after running one or two hour temperature will reach a steady state.
After bearing will rely on the heat transfer performance and their other performance continued to maintain the temperature, the temperature of the bearing and heat dissipation, operation load and speed are closely related, in general if the installation and lubrication of the bearing is not what problem does not appear abnormal temperature phenomenon, we can use the thermal sensor on the bearing the temperature monitoring, once found abnormal temperature phenomenon can be timely stop bearing operation, can effectively avoid the higher temperature of bearing damage. |
