Output Elements Installation
The output element is centred on a deep groove ball bearing (6)
(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. 4 or 5 and Table 14.
If the resulting radial force from the output element is anywhere
near the centre of the ball bearing (6) and under the max.
permitted radial load acc. Table 4, an additional bearing for the
output element is not necessary.
No appreciable axial forces (see Table 4) should be
transferred from the output element onto the clutch
pressure flange (2).
The EAS
®
-Compact
®
with a long protruding hub (Type
490._ _ 4.1 / Fig. 3) 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.
Example:
Type 490.614.0
Type 490.614.1
Fig. 3
Ball bearings, needle bearings or bearing bushings are suitable
as bearings for the output element, depending on the installation
situation and the installation space.
In order to prevent the output element (pressure flange (2))
from moving axially in the direction of the thrust washer (3)
during overload, please make sure that the bearing of the
output element is designed as a locating bearing (Fig. 5).
