Mounting on the slip-on shaft with shrink disk
The slip-on shaft has a smooth design (without keyway). For the load shaft, we recommend the
tolerance h6 (DIN ISO 286). The material must have a minimum yield stress of 385 N/mm
2
. The
slip-on shaft is axially secured to the load shaft by means of a shrink disk connection. If you have
ordered a shrink disk, it has already been installed on the slip-on shaft.
z
In case you use another shrink disk, observe the instructions of the manufacturer.
L
Only the exterior surface of the slip-on shaft may be greased in the area of the shrink disk seat.
z
Slide the slip-on shaft onto the load shaft by hand, taking into account the minimum clamping
length and the maximum permissible depth.
L
For the minimum clamping length and the maximum permitted depth of the slip-on shaft
see Chapter 9.2 "Specifications on mounting on the gear output side", table "Tbl-15".
Dirt can inhibit transmission of the torque.
z
Do not disassemble the shrink disk prior to installation.
z
De-grease the load shaft and the slip-on shaft bore in the area of the
shrink disk seat, leaving no residual traces.
The forces of the shrink disk can deform the slip-on shaft.
z
Always install the load shaft first before tightening the clamping screws
of the shrink disk.
A jamming of the shafts can lead to damage.
z
Make sure that the slip-on shaft is aligned with the machine shaft.
z
Mount the slip-on shaft onto the machine shaft without using force.
z
Do not on any account attempt an assembly by hammering or applying
pressure.
z
Tighten the clamping screws (A) of the shrink disk
evenly distributed in multiple circular passes.
z
Tighten the individual clamping screws only up to
the maximum permitted tightening torque.
L
For bolt sizes and specified torques see
table "Tbl-8".
