spirex™
One Piece Spiral flexible coupling |
|
|
|
| |
 |
|
| |
 |
|
Several
Overlapping helical cuts are machined into
one piece of material, thereby providing
for flexing properties which compensate
for angular, parallel and axial misalignments.
spirex couplings have minimum windup
and transmit torque with constant velocity.
Encoders,
resolvers and other rotating instruments
are only as accurate as the flexible coupling
that connects them to the system they are
monitoring.

spirex
couplings can be designed to your requirements
by changing the length, diameters, thickness
and height of beams, and in alternate materials
like stainless steel, copper, steel, etc.

Installation |
|
| |
spirex
couplings are precision units and must be installed
in natural position without pre-compression. The
flexibility of the coupling may be adversely affected
if installed, either in a compressed or a stretched
condition.

-
Clean
the shafts to ensure that they are free
from oil, grease or any foreign substance.
-
Mount
the spirex coupling on one shaft
and fasten the locking screws. Refer
the above figures for proper location
of the coupling on the shafts. Similarly
mount the second shaft into the coupling
bore and fasten the coupling ensuring
its natural position. In case of series
SSR and SCR, the shafts may extend into
the flexure area as shown.
-
Using
a straight edge check the alignment
at different point on the circumference,
to ensure that the straight edge is
in full contact over the entire length
of the coupling.
-
Misalignment
must not exceed the maximum permissible
values specified. In case of skewed
misalignment individual misalignments
should not be taken at maximum
