but the wreath that preloads the bearings will replace the forced coupling on the hub?
no, the installation definitely forced by greater guarantees, but still it's better than nothing. Have you thought of using bearings with integrated traction compas? also exist with double crown of spheres and adjustable.
 
the wreath with bearing with cylindrical hole I would use only for the axial locking of the bearing itself on the hub (with threaded shaft or threaded ring) from the opposite side to the shoulder. if the bearing has conical hole and the mountains on conical seat (which can be for example the shaft itself or a traction compass) with the wreath realize both radial and axial locking.
Frankly, what you posted doesn't seem to me to be a fitting of the most correct, as others told you...
 
try to search in the initial pages of the skf catalog: there are several examples with the general principles of assembly (radial locking, axial locking, preloading, expansion, traction/pressure compasses, etc.).

I attach you as an example the mounting of a swivellable bearing bond rollers, mounted on the traction compas. is a counter bearing of a elbow tree: the load can be considered mobile compared to the inner ring, therefore it has chosen to block radially the latter using a bearing with conical hole mounted on the traction compass (the wreath in this case serves to "unify" the compass under the bearing itself. the space between bearing and maschetta serves for the axial positioning of the first (important rate that must remain within a given tolerance). the outer ring is mounted with slight play in the hole on the flange, to facilitate assembly. instead it is locked axially (painted against the shouldering by a lid), because I want the bond to be a hinge and not a cart (this type of bearing, like all those with non-composable rings, is able to withstand axial loads). On the other side of the tree, instead, he mounted a non-axial bearing, in order to compensate for any thermal expansions.
It is clear that there are many other ways to mount bearings, we say that this is a rather canonical solution.

Hi.
I found this dispensation of the drawing course of machines that I followed at the university.

Surely you will be useful from slide 13 onwards:finger:
