Output Elements Installation
In case of the
EAS
®
-NC Type 450.-
the output element is
centred on a deep groove ball bearing (7) (tolerance H7/h5) and
bolted together with the pressure flange (2).
Please observe the maximum permitted screw-
in depth in the pressure flange (2) as well as
the connection dimensions "a" and "e" for the
output elements, see Figs. 3 or 4 and Table 5.
If the resulting radial force from the output element is anywhere
near the centre of the ball bearing (7) and under the max.
permitted radial load acc. Table 3, an additional bearing for the
output element is not necessary.In case of very wide output
elements and a force application of the resulting radial force
outside the bearing centre, the output element is additionally
located on the shaft, Fig. 4.
No appreciable axial forces (see Table 3) should be
transferred from the output element onto the clutch
pressure flange (2).
The EAS
®
-NC with a long protruding hub (Type 450._ _ _.1 /
Fig. 2a) is recommended for extremely wide output elements, or
for elements with small diameters.
On very small diameters, the output element is screwed together
with the clutch pressure flange (2) via a customer-side
intermediate flange.
In case of increased radial forces, a 2-bearing design (Type
450._ _ _.2 / Fig. 2b) should be used.
Example:
Type 450.61_.1
Type 450.61_.2
Fig. 2a
Fig. 2b
Ball bearings, needle bearings or bearing bushings are suitable
as bearings for the output element, depending on the installation
situation and the installation space.
Please ensure that the output element bearing is designed
as a fixed bearing (Fig. 4).
