6.3 Preassembly of the brake
– Insert the preassembled brake coil (see. 6.2) in the coil body (54/20) and lock it axially with the
circlip/snap ring (285/20).
Take care not to damage the O-ring!
– Screw the brake coil to the coil body through the second opening on the terminal link using the
second cheese head screw and lock washer.
– The protective ground connection is provided by screwing the terminal link to the brake coil.
– Push the two parallel pins (300/20) into the hole provided in the coil body.
– The pins are pushed in deep enough if they do not project from the pressure plate (49/20).
– Insert the brake springs (265/20) symmetrically into the holes provided over the perimeter of
the coil body, depending on the required brake torque (see Table 4).
– Screw one auxiliary mounting nut each on the two cheese head screws (56/20).
– Position the pressure plate (49/20) on the parallel pins and screw the two cheese head screws
into the pressure plate through the holes in the coil body (provided for the manual brake
release).
– Screw in so that no threads project from the pressure plate.
– Pull pressure plate on to the coil body by tightening the nut.
– Place the O-ring on the coil body.
6.4 Mounting the brake to the motor
– Place clip (69/20) with open side facing front in gearing of carrier (70/20).
– Slide brake disc (68/20) on carrier (70/20) (hub facing front).
– Position one half of the brake disc on the carrier and then push on to the carrier completely,
turning it slightly (hold motor shaft in place).
– The intermediate ring (299/20) is ribbed on three sides, the fourth is flat. The non-drive end
bearing end shield is designed in a similar way. Position the O-ring (392/20) on the non-drive
end bearing end shield. Position the intermediate ring on the centring fit of the non-drive end
bearing end shield and align.
– Position the O-ring (393/20) and then position the preassembled coil body with the pressure
plate on to the intermediate ring (flat sides facing each other) and screw down loosely with the
aid of the four cheese head screws (213/20).
Do not tighten screws yet!
