Composition of bearing digital model
At the beginning, most of the bearing models are composed of numbers. To distinguish bearing what kind of bearing is, it mainly depends on the penultimate position. For example, 1000828 bearing, which is the new code 61828100828. The penultimate position of the bearing is 0, which means zero category, which is now called deep groove ball bearing. Another example is 3003256. The new code is 23256300, which indicates the structure of the bearing. The penultimate digit is 3, which indicates three categories, that is, self-aligning roller bearings.
There are many methods for positioning and fixing the inner and outer rings of rolling bearings. The following are several common methods.
a) The shaft is embedded in the groove of the shaft with a retaining ring, which is mainly used when the axial force is small and the speed is not high.
b) The shaft end retaining ring fixed with screws is fastened, which can be used to bear large axial force at high speed, and the screws shall be provided with anti loosening measures.
c) It is fastened with round nut and stop washer, which is mainly used in the case of high speed and large axial force.
d) It is positioned with a conical sleeve and fastened with a stop washer and a round nut. It is used for bearings with conical holes on the optical shaft and inner ring.
e) The hole embedded in the housing groove is fastened with a circlip, which is mainly used when the axial force is small and the size of the bearing device needs to be reduced.
f) It is fastened with the bearing end cap, which is used for all kinds of centripetal, thrust and centripetal thrust bearings with high speed and bearing large axial force.
g) The shaft is fastened by inserting the circlip into the stop groove of the outer ring of the bearing, which is used when the housing is inconvenient to set the shoulder.
h) It is fastened with threaded ring, which is used when the bearing speed is high and the axial force is large, bearing but it is not suitable to fasten with bearing end cover.
