Instructions for mounting / schematic
4.2.4 Joint rod as torque holder
➢ Please refer to the customer-specific drawing for any variations in size and individual assembly
options. Please refer to the manufacturer's individual technical data for joint head rod
specifications, such as the permissible tilt angle of the joint head.
➢ A joint rod with two joint heads and two M5 cylinder head screws are required for assembly.
➢ For mounting on the measuring system, the joint rod can be screwed to one of the two M5
threaded holes in the flange. For optimum support of the measuring system, the joint rod must
be mounted at a 90° angle to the line connecting of the threaded hole to the center of the shaft,
see Figure 12.
➢ The M5 screws must be tightened with a tightening torque of 2.2 Nm and secured against
unintentional loosening with a medium-strength screw locking device.
Ensure the thread is sufficiently long for the screws to be completely screwed in.
-
➢ The minimum thread reach into the flange plate is 4 mm in steel and 6 mm in aluminum. The
minimum thread reach into the measuring system flange is 6 mm.
➢ The mounting surfaces should be free of any lubricants or dirt.
➢ The assembly instructions for the assembly of the clamping ring must be observed, see chapter:
4.2.1 "Mounting of the clamping ring (general)".
