EUROROLL-BRAKE CONVEYOR ROLLERS dia. 80 ... - Euroroll.de

EUROROLL-Brake Rollers and EUROROLL-Brake
Conveyor Rollers control the speed of the good to be
conveyed on roller tracks while they keep the conveyed
good at a constant run-off speed. This is
achieved by means of planetary gearing, which at
each revolution presses the centrifugal brake discs
against the roller body, raising it with proportional
brake force up to the brake momentum. The distance
of the Brake Rollers and the correct brake
roller type are influenced by several factors:
1. Construction and capacity of the roller track
2. Declination of the roller track
3. Characteristics of the good to be conveyed
(size, weight, sensitivity, barrel-shaped)
4. Resistance of the Brake Roller
5. Environmental conditions, e.g. wet, cold or
warm conditions
At least one Brake Roller or Brake Conveyor Roller
has to be fitted per pallet place, as only then a
controlled speed without acceleration and the appearance
of great force can be achieved. The runoff
speed should never be above 0.3 m/sec. The
run-off speed is only 0.1 – 0.2 m/sec. when the
Brake Rollers are correctly positioned. Important is
the correct adjustment of the suspension of the
Brake Rollers and Brake Conveyor Rollers. As only
by means of the necessary pressing between the
Brake Roller and the good to be conveyed (conveyor
roller or pallet) a contact free from slipping
occurs and a constant conveying speed is
achieved.
Braking Force Diagram
Braking force diagrams are a great help to choose
the correct type of Brake Rollers and Brake
Conveyor Rollers. Forces (which mainly arise due
to acceleration), which exceed the characteristic
curve, can overload and destroy the Brake Rollers.
Therefore the Brake Rollers and Brake Conveyor
Rollers always have to be fitted in pallet distance
in roller tracks or even closer to each other. This
means that the pallet in each position is always in
contact with a Brake Roller (it’s a speed controller).

BRAKE ROLLERS
BRAKE CONVEYOR ROLLERS
The EUROROLL-Brake Conveyor Rollers are
supplied in two different diameters and laid
out for different loads:
Brake Conveyor Roller dia. 80 mm
Brake Conveyor Roller dia. 89 mm
Each Brake Conveyor Roller is delivered together
with a set of suspension and therefore
can only be installed in a way, that the
Brake Conveyor Roller is suspended at maximum
level of the roller track or less. The
correct level of the moving of the elastic

suspension and the lowest level of the top of the Brake
Conveyor Roller have to be determined by carrying out
careful measurements. (Figure based on experience:
approx. 1 – 2 mm above roller upper level).
It is very important, that each Brake Conveyor Roller is
exactly adjusted and checked. When using fixed holders
the Brake Conveyor Roller will always be adjusted
above the upper level of the rollers of the roller track.
The level has also got to be determined by carrying out
careful tests and then will be exactly adjusted.

Rubberised Brake Conveyor Roller
EUROROLL supplies Brake Conveyor Rollers where the
entire length of the roller has a shrinked-on rubber
cover, which is used for steel pallets or plastic pallets.
The result is to get a better friction between the Brake
Conveyor Roller and the pallet.
Dependent on the kind of installation EURO-
ROLL-Brake Rollers can be supplied with short
or long mountings. An extensive range of accessories
to install the Brake Rollers and to ad-
EBR - 300 EBR - 300 just them exactly supplements the product
