There are many methods for positioning and fixing the inner and outer rings of rolling bearings. The following are several commonly used methods:
a) The shaft retaining ring is embedded in the groove of the shaft, which is mainly used when the axial force is not large and the rotation speed is not high:
b) The shaft end retaining ring fixed with screws is fastened, which can be used to withstand large axial forces at high speeds. The screws should have anti-loosening measures:
c) Fasten with round nut and stop washer, mainly used in the case of high speed and large axial force;
d) Use a tapered sleeve for positioning, a stop washer and a round nut, and it is used for bearings on the optical axis and the inner ring is a tapered hole.
e) Fasten with a retaining ring with a hole embedded in the groove of the casing, mainly used when the axial force is not large and the size of the bearing device needs to be reduced;
f) Fastened with bearing end cover, used for all kinds of radial, thrust and radial thrust bearings with high speed and large axial force;
g) Insert the spring retaining ring for the shaft into the retaining groove of the outer ring of the bearing and fasten it, which is used when the shell is inconvenient to have a shoulder;
h) Fastening with a threaded ring is used in the case of high bearing speed and large axial force, which is not suitable for fastening with bearing end cover.
