The TSCHAN
®
-Coupling POSIMIN
®
-PHP is a torsionally rigid steel disk coupling. It compen-
sates for angular, radial and axial shaft misalignments within defined ranges. The coupling
transmits torque without backlash through flexible steel disks loaded in tension.
The spacer can be radially mounted and dismounted without having to move the connected
machines. The distance dimension ‘E’ between the flange hubs can then be used, for exam-
ple, to service connected machines.
When the spacer is dismounted, a check of the rotational direction of the drive can easily be
performed.
The coupling is suitable for use in every direction of rotation and installation position. For ap-
plications involving other than horizontal position, it may be necessary to support the spacer.
Please consult TSCHAN GmbH, if this has not been considered when selecting the coupling.
2.1 Intended
Application
•
In order to ensure trouble-free and reliable operation, the coupling has to be sized accord-
ing to the design specifications, e.g. according to catalogue TSCHAN
®
POSIMIN
®
-PHP,
or by using the TSCHAN Design Programme, with a service factor appropriate for the ser-
vice conditions.
•
Except for the production of a finish bore with keyway, no further modifications are al-
lowed to be carried out on the coupling!
•
The coupling shall only be used and operated within the frame of the conditions as de-
fined in the performance or delivery contract.
•
Any change in the operation conditions or service parameters requires the verification of
the coupling design.
3 Storage
On receipt of the goods, immediately check that all parts are on hand and are as ordered.
Eventual shipping damages and/or missing parts have to be reported in writing.
The coupling parts can be stored in a dry place under roof at normal ambient temperatures
for a time period of 6 months. Storage for a longer period requires the application of a long-
term preservation. (Please consult TSCHAN GmbH in this respect.)
The disk packs are made of stainless spring steel. They must not be exposed to any aggres-
sive products, extreme temperatures or humidity. Do not store the disk packs along with ac-
ids, alkaline solutions or other caustic chemicals. The place of storage should be dry and free
from dust. The air humidity should not exceed 65% and condensation is not permissible.
