Electromagnetic Double Face Spring – Applied Brake
5.1 Assembly
The assembly to the motor is simple, no dismantling of the brake is required.
- Check the connecting dimensions for compatibility with the brake.
- Remove any existing transportation or bearing protections devices, as well as any burr
or impact damage.
- Check face run out of the flange mounting surface relative to the shaft to be braked
(tolerance class N in accordance with DIN 42955 should not be exceeded).
- Slightly grease shaft and fitting key with assembly paste. Mount pinion (15) and secure it
axially.
- Use suitable slings (shackles or equivalent) to move the brake cautiously across the
pinion (15) and turn the shaft or swivel the brake to engage pinion teeth with the mating
teeth of the friction disc (2). (The friction disc is pre-centered during the final acceptance
of the brake).
Caution!
Do not use force!
- offer brake onto the motor in the position specified
- tighten the mounting screws (41) to correct bolt tightening torque (as specified on the
drawing)
- To prevent mechanical blocking of the stainless steel screws (41) we recommend to
grease these screws with Klüber paste HEL 46-54
- Make sure that the electrical connection is performed by expert personnel taking into
account the installation regulations (such as DIN IEC 92).
Caution!
When mounting always assure that all seal rings and sealings are properly lying in the
accordingly provided positions (IP 66).
5.2 Mounting accuracy
The concentric run of the shaft piece on which the driving hub (15) is fixed as well as the
coaxiality and the run - out of the fixing flange must comply with tolerance class "N" of DIN
42955.
5.3 Dimensions, space requirement and mass
