Mechanical installation
This chapter provides step-by-step instructions for the installation.
Important notes
DANGER
Danger of explosion
Increased temperatures on the surfaces and in the friction gap can result when the max-
imum friction work and operating frequencies specified by INTORQ are exceeded. These
can lead to ignition.
¾
Operation is only permitted within the specified specifications.
The following must always be observed when installing ATEX brakes:
¾
The proper functioning and correct dimensioning of the brake must be ensured before it is put into op-
eration. The correct relation between the brake, motor, control and loads must be checked.
¾
If the switching times of the brake in conjunction with the control of the drive is not properly taken into
consideration, the rotational speed could increase when the motor is switched off. As a result, the brak-
ing procedure would be carried out at a much higher speed and higher friction work than assumed in
the preliminary design. This would result in higher temperatures, which would then pose a risk of igni-
tion.
¾
Check if the rotor can be pushed when it is mounted on the hub. A sluggish heavy connection between
the rotor and hub can lead to a continuous slip of the rotor. This would increase the temperature at the
friction joint.
¾
Make sure that the air gap is properly and uniformly adjusted. An uneven air gap adjustment can lead
to continuous slip of the rotor and thus to increased temperatures.
¾
When installing and dismantling the brake, make sure that no solids fall into the friction gap.
¾
Careless assembly, disassembly or operations can lead to sparking. Do not use spark-generating
tools.
¾
Mount the brake so that it does not hit any rotating components. Ensure that there is sufficient clear-
ance to the fan hood and fan blade.
NOTICE
The toothed hub and screws must not be lubricated with grease or oil.
