cemp DB 30 - Construction Method for the Brake Motors Sizes 71÷160; Construction Method for the Brake Motors Size 63

ENGLISH

A pinion (toothed hub) dq is coupled to the motor
shaft br . The brake disc dm is fitted on the toothed
hub.
The brake disc and the toothed hub, connected to
the shaft, make up the rotating part of the brake.
The brake disc can move along the axis of the shaft
on the toothed hub towards the brake holder shield,
which forms the braking surface along with the
mobile armature dl .
Three studs es are screwed into the brake holder
shield and the electro-magnet dp is secured to them
using nuts fk A and fk B. Six studs are used for size
160.
The mobile armature can slide along the axis of the
studs.
Springs fl are fitted around each stud, between the
mobile armature and the electro-magnet. These
springs are compressed using the nuts et to adjust
the braking torque.
Nuts fk A and fk B are used to adjust the air gap (see
paragraph 4.4), that is, the gap between the mobile
armature and the electro-magnet when the brake is
not powered.
A pinion (toothed hub) dq is coupled to the motor
shaft br . The brake disc dm is fitted on the toothed
hub.
The brake disc and the toothed hub, connected to
the shaft, make up the rotating part of the brake.
The brake disc can move along the axis of the shaft
on the toothed hub towards the brake holder shield,
which forms the braking surface along with the
mobile armature dl .
A pre-fitted unit (single piece) comprising the mobile
armature dl , springs fl and electro-magnet dp
completes the brake.
This single unit is secured to the brake holder shield
by fixing screws es .
Adjust the air gap (see paragraph 4.4) by turning the
fixing screws after having slackened the air gap
adjustment screws (nuts) fk A.
Motors from 63 to 160
If the motor is set up for the brake to be
mounted vertically it may feature some construc-
tion variations due to the particular installation
position.
