It is usually sufficient to monitor the operational status of the brake, but be aware of the following while brake
function is not well:
This brake works with friction force between the brake plate
⑥
, the armature
③
and the lining
⑤
,
brake lining will be worn while operation. It is necessary to change brake plate
⑥
, the armature
③
and
the lining
⑤
after 3 times of ‘Gap adjustments’.
It is necessary to clean up the brake every 6 months because it will have wear of dust and
particles due to the brake operation.
(1) Brake structure
(2) Brake inspection and gap adjustment
1) Loosen the bolts
⑧
for brake cover and remove the brake cover
⑨
.
2) Tighten Adjustable nuts
⑩
(3 pcs.) clockwise, and adjust the gap to range listed below with
verifying the gap dimensions with a thickness gauge.
Check the gap at several points along the circumference to be the Fixed core
④
and Armature
③
are
parallel to each other, then apply locking agent. (Do not repeat loosening and tightening, the
adjustable nuts
⑩
may damage to the nuts and lose locking effect.)
【
Note
】
・
Before tightening the adjustable nuts
⑩
, insert the hexagon socket screw key into the hexagon socket
of the guide bolt so that the guide bolt may not come loose by rotating together.
・
Replace with a new adjustable nut
⑩
if the adjustable nut
⑩
is removed or repeatedly tightened and
loosened. (Size 0.75kW:M5
×
P0.8, 1.5,2,2kW:M8
×
P1.25 ) Remove grease from the guide bolt
⑬
and
the adjustable nut
⑩
, and apply anti-loosening liquid in this case. Do not take down the brake
because it may make reassembly impossible and incorrect reassembly may lead to a brake
malfunction.
3) After adjusting the gap, make sure the brake operates normally by connecting to power source.
Observe the gap is appropriate to prevent the armature
③
, brake plate
⑥
and lining
⑤
from
contacting during rotation. If they do come in contact, readjust the gap.
