Shrink Disk; Fitting The Shrink Disk - Siemens FLENDER B3 E Series Assembly And Operating Instructions Manual

6.7

Shrink disk

The shrink disk realizes a press­fit connection between a hollow shaft and a stub/machine shaft (in the
following called "stub shaft"). The interference fit can transfer torques, bending moments and forces. The
jointing pressure between the hollow and stub shafts generated by the shrink disk is essential for the torque
and force transmission.
The shrink disk is delivered ready for installation.
The shrink disk must not be dismantled before mounting for the first time.
Fitting and start­up must be carried out by properly trained specialist personnel. Prior
to start­up these instructions must be read, understood and adhered to. We accept no
liability for personal injury or damage due to non­observance.
6.7.1

Fitting the shrink disk

Before beginning installation, the hollow shaft and the stub shaft must be carefully cleaned.
Observe manufacturer s instructions for handling lubricants and solvents.
Do not allow cleansing agent or solvent to affect surfaces with paint coating.
The bore of the hollow shaft and the stub shaft must be absolutely clean, free of grease
and oil in the area of the shrink disk seat.
This is essential for safe and reliable torque transmission.
Do not use contaminated solvents or dirty cloths nor cleansing agents containing oil
(such as paraffin or turpentine) for removing grease.
