Open the catalog to page 5Definition - Servo Couplings: Servo couplings are compensating couplings with a backlash free and conformal torque transfer providing high torsional stiffness and a low moment of inertia. According to these requirements, JAKOB metal bellows couplings can be regarded as the ideal solution. For more than 40 years, they have proven themselves in numerous servo drives as an excellent choice. Elastomer couplings with a flexible polyurethane spider can also represent a perfect alternative for different applications because of their product-specific advantages. All JAKOB servo couplings are...
Open the catalog to page 6Safety Couplings I General Definition – Safety Couplings: Due to the constantly increasing automation and dynamics of modern work processes, the devices which protect the complex and expensive units against damages in case of errors are becoming more important. JAKOB safety couplings reduce expensive machine damages, repairs and downtime by acting as torque limiters and overload protection absolutely reliably. JAKOB safety couplings are the life insurance for your machines, no matter whether the error occurs due to incorrect operation, programming error, material overload or tool breakage....
Open the catalog to page 7Couplings I Dimensioning Technical Information - Definitions / Details: Nominal torque of the coupling: TN - [Nm] The nominal torque of the coupling defines the max. load of the prolonged alternating-stress strength. If in normal operation, TN is not exceeded, an infinite number of operation cycles can be carried out (see d „durability“). The values for the moment of inertia are defined for medium hub-bores in the given diameter range Dmin/Dmax. Conversion: [kgcm2] = [10-4kgm2] Torsional stiffness: CTK - [Nm/arc min] The values for the specific torsional stiffness of all couplings are...
Open the catalog to page 8Couplings I Dimensioning c) according to shaft diameter: After selecting the coupling type, it must be checked whether the requested shaft diameter corresponds with the allowed diameter (Dmin / Dmax) of the hub bores. Another coupling type or size must be chosen, if the shaft diameter is overdimensioned in relation to the torque, which means it is larger than Dmax of the hub. note: hub bores which are smaller than “Dmin” are possible, but an optimal transfer of the nominal torque cannot be guaranteed in this case, so a reduction of the drive torque is necessary. d) durability: The...
Open the catalog to page 9Couplings I Installation Instructions Alignment of shafts: Axial and angle misalignment are usually without problems and also simple to measure. To obtain the lateral misalignment, it is recommended to proceed as follows: Fit a dial gauge with an appropriate holding device on one shaft end or on one hub of the coupling and bring the feeler onto the second shaft end or onto the second coupling half (sketch). Now the shafts are turned with the dial gauge and the deflection is read. One half of the total deflection is the lateral misalignment. The admissible value for the shaft misalignments...
