Serie 6.11 CATALOGUE
Serie 6.11 CATALOGUE
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 provides technical information on torque, reaction times, and friction material performance, adhering to VDI 2241 and DIN 1304 norms.
The technical section explains concepts and formulas for calculating and selecting clutch-brakes. Key terms include Transmissible Torque, Slip Torque, Residual Torque, Loading Torque, Characteristic Torque, and Acceleration Torque. Time terms for torque transmission include reaction delay, rising time, and slip time, crucial for understanding clutch-brake dynamics.
This section details various series of hydraulic clutch-brake combinations, designed for specific applications and performance requirements.
Different series of hydraulic clutches and safety brakes are outlined, 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. Effective heat dissipation is crucial to prevent surpassing the thermal capacity of clutch-brakes.
This catalogue serves as a reference guide for selecting and understanding hydraulic clutch-brake systems. For special applications or further assistance, contacting the technical department is recommended.
Hydraulic clutch-brake 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 provides detailed technical specifications and operational guidelines for hydraulic clutch-brakes, emphasizing material selection, lubrication, and thermal management.
This document provides detailed technical specifications and options for GOIZPER's hydraulic clutch-brake systems, focusing on their application in presses.
Assembly options include mounting with locking rings, keyways, at the shaft end, or between the flywheel and frame. Lubrication types include forced and splash lubrication. Piston systems include conventional and progressive systems.
GOIZPER offers peripherals for hydraulic clutch-brake systems, including oil collectors, rotary unions, control valves, control units, and power packs.
The systems offer a wide range of operational torques, with the ability to adjust clutch and brake torque by adding or removing plates and springs.
Detailed tables provide specifications for different series and sizes, covering static clutch torque, dynamic brake torque, weight, maximum speed, and pressure requirements.
Control valves for progressive clutching and braking ensure smooth operation and meet safety regulations.
The document outlines specifications for hydraulic control units and safety valves, including connection holes, voltage requirements, and valve spool redundancy for safety compliance.
To engage the clutch, electrovalves must be activated simultaneously. Both valve spools must be engaged for machine operation, while only one is needed to stop the machine.
The document emphasizes redundancy in valve spools to meet safety regulations and recommends verifying spool positions before each cycle.
Control units are designed to mount GOIZPER safety valves and include components like accumulators, pressure limiters, and manometers.
Details are provided for power packs with heat exchangers, including components like pressure limiters, filters, and thermostats.
Specifications for various series of hydraulic clutches and brakes are provided, including torque, operating pressure, speed, and weight.
Forms are included for selecting CL-BR units and mechanical presses, detailing customer information and technical data of the press.

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):...

MOMENT OF INERTIA J 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: J = 77 • D4 (kgm2) When the moment of inertia is not referred to the clutch shaft, it is necessary to reduce it to this shaft. The following formulation is used. Jred = J • i2 (kgm2) J : moment of inertia of the shaft masses at any speed. (kgm2). Jred : moment of inertia reduced to the clutch shaft (kgm2). i : speed ratio between...
