Assembly
8.1. General assembly instructions
Before beginning with assembly, check for the completeness of the delivery (see chapter
2.3 Parts list) and the dimensional accuracy of the bores, the shaft, the fasteners and the
keyway (see 7. Technical prerequisite for reliable operation).
The parts are to be cleaned of preservative agents, the O-rings may not come into contact
with solvents or cleaning agents as a result.
8.2. Assembly description
1. Firstly, insert the O-rings (item 8) into the groove of the coupling halves (item 2). To en-
sure that they don’t fall out, you can apply some grease into the groove. Also lubricate
the sealing plane surfaces of the coupling halves.
2. Slide the coupling halves (item 2) onto the shaft ends. Ensure hereby that the O-rings
(item 8) are not damaged.
3. Mount the hub (item 1) on the input and output side. The shaft end may not protrude
out of the hub for normal applications.
→ facilitated sliding onto the shaft can be achieved by heating up the hub (approx.
80°C)
→ the O-rings (item 8) may not touch the heated-up hubs here
4. Slide the units in axial direction until the O measurement is achieved (see chapter 2.2
Dimensions)
→ if the units are already mounted, the O measurement can be adjusted by sliding the
hubs onto the shaft. Here, a sufficient supporting length of the keyway must be en-
sured.
→ if O is not adhered to, the coupling may be damaged.
-
align the hubs (item 1) to one another.
-
the available misalignments should be measured using suitable measuring equip-
ment e.g. dial gauge, straightedge, feeler gauge or depth gauge.
-
the maximum permissible misalignments may not be exceeded.
5. Lightly lubricate the gearing of the coupling halves (item 2) with lubricant and slide on
the hubs (item 1).
6. Align the fit bores of coupling halves (item 2 and 9) to one another.
7. Insert the seal (item 6) between coupling halves and screw together the coupling halves
with fitting screws, as well as spring washers and nuts and tighten to the specified tight-
ening torque (see table 8.1).
Attention!
Use suitable means of protection when working with the heated hubs. Contact
with the heated hubs without safety gloves causes burns.
