Functional description
Machine
:
DAF 330 consists of a frequency-controlled motor of constructional
size B3 (DIN IEC 34).
Note
:
it is designed for
2 : 1 suspension
with single or double rope wrap.
Dependent on motor type and controller the actual braking energy can be
a) supplied to resistors (for motor data see 2.10)
b) regenerated sinusoidally to the mains (see 2.10/2.11)
Motor shaft and rope pulleys are equipped with life-time lubricated roller
bearings. The traction sheave and the integrated brake disk are pressed and
screwed onto the conical end of the motor shaft. The screws are secured
against unintentional unscrewing by means of Loctite (type 241).
The gearless machine does not have a self-locking device
.
Brake
: an electromagnetically operated outside dual-circuit shoe brake is
mounted on the motor casing. Two independently operating brake shoes with
preset spring resistance press the brake lining onto the brake disk.
The braking force is adjusted in such a way that one braking shoe can stop
the car loaded with full loading capacity.
Electrically operated brake test switches monitor the position of the
brake
shoes and the wear of the brake linings: in the case of malfunction or
reaching of preset wear limit the drive will be disconnected.
An electrically operated dual expanding magnet is used for releasing the
brake (one electromagnet for each brake shoe).
A brake release lever is mounted on the dual expanding magnet for manually
releasing and simultaneously operating both brake shoes.
Machine frame
: in the as-delivered condition the machine frame necessary
for mounting the machine is a completely pre-assembled unit (incl. mounted
rope pulley in the case of double wrap). (For details concerning machine
frame and its dimensions see 2.12)
Additional parts
:
additional parts necessary for operation, servicing and
trouble-shooting such as blocking clamp, rope grip, handwheel and hydraulic
lever are delivered optionally.
Note
: for description of use as intended see chapter 9.2
