2 Lutex Clutch/Brake Combination LKB and LKB plus Application Area The pneumatically actuated Lutex LKB is a dry single plate combined clutch/ brake combination (it is referred to the following text as the CBC). Originally developed for use on presses and shearing machines it is particularly suitable for applications where medium and large inertias are to be accelerated or decelerated. The heat resistant properties ErgänzungsBaureihe LKB plus Die LKB plus basiert auf der bewährten LKBBaureihe. Die Anschlussmaße werden mittels Distanzring und Modifikation der Kupplungsbohrung so angepasst, dass die LKB plus gegen gängige Wettbewerbsbaureihen problemlos ausgetauscht werden kann. Function The brake disc is mounted on the press/ machine frame whilst the clutch disc is mountig on the flywheel. The piston is mounted on the hub and is free to move axially between the hub and the cylinder. In the nonair pressure state spring tension keeps the brake disc in contact with the cylinder. The brake is on. As air is inflowing into the cylinder the spring tension is overcome and the brake begins to release, the increase in air pressure engages the clutch. The friction discs are available with either 1point or point mounting (see schema on page ). In the point system the mounting points can be either long or short depending upon the machine frame requirements. of the friction surfaces enables the Lutex CBC to achieve the high operating cycle required by presses. Its compact construction allows the CBC to be mounted in a very small space between the machine frame and the flywheel. The CBC conforms to the safety requirements of the EN 69/06. Features and Benefits of the Lutex Clutch/Brake Combination (CBC): The types LKB and LKB plus are exchangeable with the most standard CBC LKB und LKB plus decken die Anschlussmaße der gängigsten Baureihen ab Lowmaintenance, safe, reliable Low inertia Large shaft bore High heat resistant Low air consumption High frequency of operation Accurate repeatability High volume friction surfaces Highly stressable friction linings with maximum durability point mounting system with plastic collar for noise and vibration absorption Quick and easy replacement of the friction discs Several methods of mounting the friction discs Wide range of brake and clutch torque Ability to adjust worn friction discs (on sizes to 7) Certificate of conformity to safety regulations Advice of abrasion (as an option) Application of clamping elements (as an option)
