Operating speed must be equal or less than permissible speed. ® METALDRIVE Coupling Balancing. ® All the components of the METALDRIVE couplings are completely machined (spacer excluded) and balanced in class DIN ISO 1940-1 Q 6,3. Therefore, the balancing is unnecessary in most applications. In cases where a higher degree of balancing is required, it is important to consider: » Rotation speed and coupling diameter. » Rotation speed and intermediate shaft length. » Rotation speed and special balancing need of the machine. ® According to the requirement, METALDRIVE coupling can be statically or dynamically balanced according to DIN ISO 1940-1. As a standard, the balancing is made on the single coupling component. On specific request the assembled coupling can be balanced. Also as a standard the balancing is made before the key seat machining. The balancing after the key seat machining is made on specific request. Permissible speed could be limited by the weight and critical speed of spacers. Please consult jbj Techniques technical office: +44 (0)1737 767493 or email: info@jbj.co.uk No balancing required Working temperature: -40°C to + 250°C. Misalignment ® METALDRIVE couplings with double disc packs allow axial, angular, and radial misalignment. ® METALDRIVE couplings with a single disc pack allows only axial and angular misalignment. Please note that application must not have the maximum value of axial and angular misalignment at the same time.

www.jbj.co.uk/couplings.html #DriveLineHarmony Definitions 5 T = peak torque capacity for a maximum of 10 times (Nm) Kmax T = torque transmissible by the coupling at the maximum RPM with the allowable misalignments (Nm) Kn T = maximum torque variation allowable by the coupling from the nominal torque TKN with a frequency of 10 Hz (Nm). KW Coupling Selection » Calculate the nominal torque to be transmitted: T = nominal torque of the machine (Nm) N P = input power (kW) n = RPM (1/min) » Verify coupling nominal torque TK : TK ≥T ∙k N n N k = service factor » Verify coupling maximum torque with machine peak and starting torque. It is allowed up to 5 peaks or start up per hour: T ≥ T Kmax S T = starting or peak torque (Nm). S » In case of direct start with AC motor, it is important to consider driver and driven inertias. In case of transmission with torque inversion, the maximum torque variation TW should not be higher than the maximum coupling torque TKW. TKW ≥ TW » Verify working conditions. Particularly maximum speed must not exceed the permissible value. Dynamic balancing (optional) allows higher speeds. Permissible speed could be limited by the weight and critical speed of spacers.

www.jbj.co.uk/couplings.html #DriveLineHarmony Installation & Maintenance ® METALDRIVE Disc Couplings ® Metaldrive vertical assembling ® METALDRIVE couplings come unassembled unless ordered to be assembled. When mounting the coupling, it is important to follow the specific recommendations. ® Due to the modular design of the METALDRIVE coupling, single parts can be replaced. For optimum performance all components must be in perfect conditions. ® METALDRIVE couplings are designed for horizontal mounting. In case of vertical mounting, the coupling weight must be supported. » Carefully clean bores, shaft ends and the flange where the screws are positioned. » Position the hubs on the shafts of the machines. Hub faces must be flush with shaft end. Introduce setscrew and tighten properly. » Position the driver and driven unit to be connected. » Carefully align the shafts to be connected. Proper initial alignment allows misalignments during motion and ensures transmission durability. It is therefore suggested to check shaft alignments with an indicator before the machine start up. » Mount the disc pack with screws and nuts. Tighten to torque Ms holding the screws and turning the nuts. » Install the spacer between the hubs and connect it to the already assembled disc pack with screws and nuts (in case of long spacer, it is important to support the spacer). Tighten to torque Ms holding the screws still and turning the nuts. » Check shaft alignment again. When hubs are machined by the user, it is recommended to ask for correct concentricity and perpendicularity tolerances which could affect coupling life. » There is no need for lubrication. Safety norms All rotating parts must be protected against any possibility of contact with people. Protection must be designed so that even in case of coupling failure, personnel and equipment is protected. 11
