Further information
You can find additional information about the couplings in the coupling operating instructions
provided in the complete gear unit documentation.
3.10 Shrink disks
A shrink disk is provided as a frictional clamping connection between the gear unit hollow shaft
and the driven machine on shaft-mounted gear units.
The shrink disk allows an interference fit to be created between a hollow shaft and a stub shaft
(machine shaft), referred to hereafter as "stub shaft". The interference fit is capable of
transferring torques, bending moments and forces. Crucial to the successful transmission of
torques and/or power is the joint pressure between the hollow and stub shafts generated by the
shrink disk.
Further information
Further information about the shrink disk can be found in the shrink disk operating instructions.
These are included in the complete documentation for the gear unit.
3.11 Heating
Introduction
At low ambient temperatures it may be necessary to preheat the gear unit oil before switching
on the drive or while it is in operation.
Heating elements
Heating elements can be used for these applications, for example. Heating elements convert
electricity into heat and transfer this to the oil in which they are immersed. The heating elements
are installed in protective tubes in the housing so that they can be replaced without draining off
the oil first.
