Mounting
of Bearings
Hanged Ball Bearings
There are many advantages in using miniature and instrument
ball bearings which have a flange on the outer ring.
Stepped housing bores, which make it impossible or very
difficult to maintain accurate alignment of both bearing
fits, are not necessary. There is also no need for the
use of circlips, which create difficulties in small
housing bores or thin walled housings (Fig. 7).
Furthermore the assembly of flanged bearings in relatively
narrow housings (i.e. gearboxes) has proved effective
(Fig. 8).
If duplex bearings are used, the use of a flanged bearing
simplifies the design of the locating bearing. The axial
position of the Duplex bearing pair can be determined
precisely for this arrangement (Fig. 9).
Ball Bearings with Extended Inner Rings
Ball bearings with an extended inner ring can simplify
the design of various assemblies. Shims, washers and
other spacers are unnecessary. Stepped shafts are also
redundant (Fig. 10).
Ball Bearings with Reinforced Outer Rings
Ball bearings with their outer rings supported by a
fitting in the housing can take the highest loads. To
increase the load capacity of ball bearings which are
not built into housings different types such as “special
ball bearings with reinforced outer rings” were developed
and are used as so-called rollers (Fig. 11). |
