Installation
Due to its optimum construction the ROBA
®
-ES coupling offers
the possibility to connect the coupling axially after the hubs have
been assembled onto the drive or driven shafts.
Any subsequent screwing together and special housings are not
necessary
(see Installation Examples figures 5, 6 and 15).
Installation of the Coupling Halves (Hubs)
Installation of the Clamping Hubs (Item 0 / Fig. 7)
The hub bores and the shaft ends must be
completely grease-free during installation.
Greasy or oily bores or shafts do not
transmit the maximum coupling torque.
Please make sure that the key sits securely
for designs with keyway.
Please see guideline under ATEX!
The clamping hub must be completely
relaxed; if necessary, loosen the screws by
several thread turns.
1)
Mount the coupling hubs (0) onto both shaft ends using a
suitable device and bring them into the correct position.
2)
Tighten the clamping screw (0.1) using a torque wrench
evenly to the required torque acc. Table 1.

Installation of the Clamping Hubs Compact
(Item 5 / Figs. 8 and 9)
The hub bores and the shaft ends must be
completely grease-free during installation.
Greasy or oily bores or shafts do not
transmit the maximum coupling torque.
Please make sure that the key sits securely
for designs with keyway.
Please see guideline under ATEX!
The clamping hub must be completely
relaxed; if necessary, loosen the screws by
several thread turns.
On Sizes 14 and 19
1) Mount the coupling hubs (5) onto both shaft ends using a
suitable device and bring them into the correct position.
2) Tighten the clamping screw (5.1) using a torque wrench
evenly to the required torque acc. Table 8.
On Sizes 24 to 38
1) Mount the coupling hubs (5) onto both shaft ends using a
suitable device and bring them into the correct position.
2) Tighten the clamping screws (5.1) alternately and in several
tightening sequences to the tightening torque stated in Table
8. Please make sure that the gap "X" (Fig. 9b) has the same
size on both hub sides. If necessary, re-adjust it.
