description
The Turborex TX - TX/HD - TS - TS/HD brakes, made entirely by Renova in its factory, are mainly designed for use in the
field of tension control of unwinding materials, an application that requires excellent heat dissipation and great
sensitivity. tension control on core, which by varying the diameter, require a continuous variation of the braking
parameters to guarantee the quality of production. A brake with excellent cooling capacity was thus created to ensure
constant performance during its work, infinitesimal wear of the friction elements with consequent practically zero
emission of fine dust to protect the health of the personnel present next to the machine. Maintenance costs are
therefore very low and limited over the years. Particular attention was then paid to the flexibility of the brake in order
to offer performance adaptable to the various types of processing. There are thus numerous possibilities to customize
the brake by varying the number of pistons that operate it, their size, the number of discs, the material of the friction
pads and the adoption of the Selematic system to enhance its sensitivity to low torques.
THIS COMPONENT IS DESIGNED TO BE INCORPORATED IN A MACHINE AND CANNOT WORK
INDEPENDENTLY.
IT IS FORBIDDEN TO USE IT IF ITS USE ON THE MACHINE DOES NOT COMPLY WITH THE REGULATIONS
IN FORCE.
functioning
The brake is activated by a series of pneumatic actuators (cy piston), mounted uniformly in the cover; the
number can vary from 2 to 6 according to the needs of the couple. These actuators (which we will call from now on
simply pistons) can be connected all together or even in groups (2 + 4) (2 + 2) in order to diversify the torque according
to the type of use: voltage control braking and emergency braking, braking of papers with different weights or reel sizes,
etc.
The pistons compress the pressure disc, used as a wear indicator, which in turn presses a series of steel discs, which
slide on teeth, against brake linings mounted on supports that slide on 4 guides.
A series of springs separates the discs in the absence of pressure, eliminating residual torques that can hinder the
positioning of the coils or other.
The TS version (Turborex Selematic) is instead the more “flexible” version compared to our normal Turborex.
Constructively identical, in this brake the only variant lies in the springs. While the Turborex has 16 identical springs (12
for the HD version), the Selematic springs are designed to have different stiffnesses and resistances, from the hardest
located between the first disc and lining plate, to the softer one, located near the last record. This involves a wider use
than the standard Turborex, managing to adapt to non-continuous work changes. The Turborex Selematic, therefore, is
recommended in particular uses where there are frequent changes in work, pressure, etc... while for continuous and
uniform uses, we recommend the standard Turborex.
The heat generated by the action of the brake is disposed of by 2 peripheral fans, one under pressure and the other in
suction, which force the air to pass through the disc pack, cool the surfaces and maintain constant working
temperatures.
The maximum operating pressure of our TX - TX/HD - TS - TS/HD brakes is 6 Bar. Renova strongly advises against
using a higher pressure in order to avoid breakdowns and malfunctions harmful to the machine
and/or to the 'operator. We also remind you that incorrect use of the brake does not fall within our
warranty coverage guidelines.
