DESCRIPTION OF OPERATION
On this brake, the magnet coil is a separately enclosed unit mounted between an inner and outer armature. When the coil is
properly energized, the armatures are attracted to each other until their outer poles seal. The action of the armatures moves the
shoes away from the wheel. The inner armature moves the inner shoe and the outer armature moves the outer shoe. When the
coil is de-energized, the compression spring forces the armatures apart and presses the shoes against the wheel.
PROCEDURE FOR INSTALLATION AND OPERATION
(Refer To Dimension Drawing For Mounting Dimensions)
1.
Assemble brake wheel “B” on motor shaft
2.
Back off lock nut “U” and pull rod nut “P” about
one inch.
3.
Back off lock nut “T”. Turn screw “C” clockwise to
lift the wedge at the top of the inner shoe lever “L”.
4.
Slide the brake into place around the brake wheel
“B” and start bolts into the base mounting surface.
5.
Loosen the holding screws “K” on both shoe
levers leaving only a light grip.
6.
Push the shoe levers “N” and “L” against the
brake wheel “B” and check to insure shoes fit
evenly across the wheel face.
7.
Bump the base into the best position to get the
most favorable fit of the shoes against the wheel
“B”. C/L of the wheel must be aligned with the
punch mark of base to obtain proper horizontal
positioning of the brake, and with C/L of shoe
pivot sockets to obtain the proper vertical
positioning of the brake.
8.
If the mounting surface is not flat or is not parallel
to the shaft axis, shimming may be necessary.
Tighten the holding bolts to hold the base firmly in
place.
