10.3 Brake/slipping clutch assembly
10.3.1 Operation
The parts of slipping clutch are mounted
free on the gear input shaft (1). Other
brake parts are mounted on the gear
flange.
The spring (9) keeps a pressure
between the slipping clutch lining (4) and
brake disc (3).
The nut (8) maintains the assembly on
the gear input shaft.
When the coil (1) is energized, during
lifting or lowering, it pulls the brake disk
(3)
(releasing the brake and slipping
clutch disc (3) there is a play X for this
purpose).
The disks (3 and 4) turn freely,
transmitting the movement to the pinion
(7).
Braking occurs when the coil is no longer energized and the spring (10) drives back the brake lining
against the disk (3).
10.3.2 Adjustment of the slipping clutch:
•
Hook a load of 1.25 times the nominal load into the hoist.
Note : The machined adjustment value is 1,4 x the nominal load, because the linings are not run
in
•
Remove the brake endcap and the sealing.
•
Raise the load at slow and fast speed.
•
Use a key to turn the adjusting nut (8) in the required direction.
−
Turn the nut clockwise to increase the torque.
−
Turn the nut counterclockwise to decrease the torque.
•
Repeat steps 3 and 4 until the load can barely be lifted at fast speed. The slipping clutch is now
adjusted.
•
Fit the sealing and the brake endcap.
•
Check, at fast speed, the lifting of a nominal load.
)
Remind : The value of the factory setting is 1,4 x the nominal load because friction lining are not
running in yet.
,
That when the slipping clutch is adjusted the brake end cap must be removed and the
motor must not be running.
,
Do no touch the moving components. Before pressing the "lift" button on the control
box, check that there is nothing in contact with the adjusting nut (key, for example).
