Hydraulic Clutches and Brakes Catalogue - Goizper Industrial
Hydraulic Clutches and Brakes Catalogue - Goizper Industrial
This document is a comprehensive catalogue for hydraulic clutches, brakes, clutch-brake combinations, spring set safety brakes, and accessories, applicable in industries such as metal forming, automotive, marine engineering, and machinery transmissions. It includes technical information on torque calculations, reaction times, and performance of friction materials, adhering to VDI 2241 and DIN 1304 norms.
The technical section covers essential concepts and formulas for selecting and calculating clutch-brakes. Key terms include Transmissible Torque, Slip Torque, Residual Torque, Loading Torque, Characteristic Torque, and Acceleration Torque. Time terms for torque transmission, such as reaction delay, rising time, and slip time, are also explained.
This section details various series of hydraulic clutch-brake combinations, designed for specific applications and performance requirements, including conventional and progressive units.
Different series of hydraulic clutches and safety brakes are presented, emphasizing the importance of selecting the right series based on operational needs.
The performance of friction materials is influenced by transmitted power, temperature, slip speed, and material combinations. The document highlights the importance of managing heat dissipation through lubrication.
These combinations are used in mechanical presses, shears, and punching machines, offering silent operation, low inertia, energy savings, and minimal maintenance. They operate at a nominal pressure of 60 bar with a forced lubrication system.
The document discusses the use of tempered steel against sintered bronze for wet operations, with friction surfaces designed to manage thermal load and lubrication flow.
Sintered discs have high thermal conductivity, allowing temperatures up to 350°C. Lubrication influences heat dissipation, with specific values for splash and forced lubrication.
The braking angle is divided into reaction and mechanical braking angles, with formulas provided for calculating slip time and total braking time.
Formulas are provided for calculating necessary torque in eccentric presses, considering factors like turning torque and press force.
GOIZPER has developed a patented clutch-brake unit with a progressive piston and valve to regulate clutching and braking.
GOIZPER offers a range of products including clutch-brakes, oil collectors, rotary unions, control valves, control units, and power packs.
The document outlines specifications for hydraulic control systems, including redundant spools in control valves for safety compliance. It also details assembly options, lubrication types, piston systems, and enclosure types.
Before each cycle, verify that both spools are in their initial position using pressure switches as part of the external self-control process.
Details on conventional control valves for hydraulic clutch-brake systems are provided, specifying the need for simultaneous activation of electrovalves.
These units are designed to mount GOIZPER safety valves and include components like accumulators and pressure limiters.
Details are provided for power packs with heat exchangers, including cooling power and tank volume.
Specifications for various series of hydraulic clutches and brakes are provided, including torque, operating pressure, speed, and weight.
The document includes a data form for selecting CL-BR units for mechanical presses, detailing required torque and operating conditions.
Tables with detailed specifications for hydraulic clutches, brakes, and power packs are included, essential for selecting appropriate components.

Residual torque Mr: torque transmitted when the system is not actuated. It depends on mounting position, (horizontal, vertical, or inclined), speed related to disc surface, oil flow, & viscosity. When vertical or inclined mounting, the residual torque increases very much, so the generated heat is increased as well. Loading torque ML: necessary torque to activate the elements in the machine, taking into account its performance, the action speed, etc. Characteristical torque Mk: It is the torque indicated in the catalogue. Acceleration torque Ma (deceleration torque when the value is negative):...

It is important to consider the moment of inertia “J” before making the following calculations. For example, the moment of inertia of a solid iron cylinder which is 100mm thick with an outer diameter D (in mm) is obtained with the following formulation: Es importante para los distintos cálculos que se indican posteriormente considerar el concepto de momento de inercia “J”. Así por ejemplo, el momento de inercia de un cilindro macizo de hierro de 100 mm de espesor, siendo su diámetro exterior D (en m), se obtiene de la fórmula: When the moment of inertia is not referred to the clutch shaft, it...
