description
The Turborex TXP - TXP/HD - TSP – TSP/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,
requires 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
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 TXP - TXP/HD - TSP - TSP/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.
