4.6 Attach the coupling piece to the tube motor
The conditions and starting points that follow are applicable.
•
Use pop-rivets to attach the coupling piece (16) (for a winding tube ø50 mm) to the tube (1.1).
Use a
minimum
of
4
pop-rivets (18) with a
minimum
diameter of
5 mm
.
Do the procedure that follows.
1.
Put the coupling piece (16) into the tube (1.1) of the tube motor (1). Make sure that the distance
into the tube is sufficient to drill the holes (d) correctly in the coupling piece (16)
and
the tubes
(1.1/17). For the four recommended drilling positions (d) refer to illustrations 4.6.1/D-D. Drill
only in the permitted part from the open end of the tube (1.1).
Note:
Drill the holes for the
winding tube (17) in §4.7.
2.
Drill one of the holes for the pop-rivets (18) into the tube (1.1) and coupling piece (16)
(minimum of ø5.2 mm if pop-rivets of ø5 mm are used).
3.
Use a pop-rivet pliers to attach the pop-rivet (18).
4.
Drill the holes for the other three pop-rivets (18).
5.
Use the pop-rivet pliers to attach the other three pop-rivets (18).
6. Put the winding tube (17) on the coupling piece (16) at a small distance from the tube motor.
This distance is temporarily necessary when the cord (20.1) is pulled through the winding tube
(17). Refer to step 2 of §4.7.
Do not drill into the tube motor more than 120 mm* from the open
end. *For the tube motor 550039 this is 194 mm.
Make sure that the connections between the winding tube and the
tube motor are strong enough for the supplied drive torque.
Make sure that the connections between the winding tube and the
tube motor are attached as smooth as possible.
This is important for the screen cloth.
