6.1 Additional regulations for flange bolted connections
6.1.1 Requirements of connecting flange and bolted connections
For fixed length universal joint shaft or joint coupling:
A connecting flange can move lengthwise through a floating
bearing in order to be able to push the universal joint shaft
over the centering collar and compensate for possible length
changes (e.g. due to heat elongation).
The use of universal joint shafts with length compensation
assumes that the connecting flange sits firmly on the shaft of
the connecting units.
Select material that permits the use of bolts of the property
c
lass 10.9 ( Fig. 6.1, page 36, Pos. m).
With the use of materials with lower property class values, the
torques that can be transmitted by the flange connection and thus
also the universal joint shaft are reduced.
With use of materials with lower property class values:
reduce prescribed tightening torque of the bolts accordingly
( Tab. 6.2, page 40, area A, column 5)
The dimensions of the connecting flange ( F
ig. 6.1, page 36 and
Tab. 6.2, page 40) correspond to those of the universal joint shaft.
Exception:
Execute locating diameter c with clearance: fit H7/h6
( Tab. 6.2, page 40, area A, column 11).
For universal joint shafts with rota > 550 mm: dimensions of
the connecting flange and bolted connections as well as
tightening torques see dimensional drawing of the universal
joint shaft.
The relief diameter f
g
on the universal joint shaft flange is not
suitable for locking hexagon head bolts or nuts.
A relief diameter f
a
on the connection flange is suitable for
protection against twisting.
