4.4 Assembly of the hubs
A T T E N T I O N !
We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
4.5 Assembly of the RADEX
®
-N clamping ring hubs on the
DATAFLEX
®
torque measuring shaft
The force is transmitted through a frictional connection. The fit for the shaft and clamping ring hub is H7/h6.
During assembly please pay attention to the following procedures:
Please clean and degrease the contact surfaces of the hub bores and the shafts before assembly.
!
C A U T I O N !
Oil and grease with Molybdenum Disulfide or other hydrocarbons as well as grease paste
should not be used.
The clamping screws must be lightly unscrewed, the clamping ring hub should be placed on the shaft and
adjusted to the L
6
dimension (see illustration 7 and 8).
The clamping screws must be tightened evenly crosswise. The tightening torques should be increased
gradually. This procedure should be repeated until the tightening torque of all of the clamping screws
corresponds to the value given in table 5.
