2 2 EAR COUPLIN C / C-ECO RIID COUPLIN C ear couplings C are flexible shaft connections suitable for a positive torque transmission. They ensure to compensate radial, axial and angular shaft misalignments. The gear coupling is made of high quality tempered steel with grease lubrication and O-ring seal. ear couplings C are used in all areas of mechanical engineering and offer a long service life with maximum reliability, resulting from the optimal grease lubrication of the crowned spline. The couplings are generally suitable for a horizontal assembly. pecial types are suitable for vertical assembly, too. The range of gear couplings includes sizes from 50 to 1000 with torque transmissions from 1920 Nm to Nm, these are suitable for shaft diameters from 20 to pecial types, adapted to your application requirements, are possible in a short delivery time! TOOTH PRINCIPLE The crowned spline principle results in case of angular and radial misalignment the avoidance of edge pressure in the spline. Optimal friction conditions of the spline with an almost wear-free operation, resulting due to the permanent grease lubrication, lead to a long service life expectancy of the coupling.

7 RIID COUPLIN EAR COUPLIN C / C-ECO 7 C-ECO ear couplings C-ECO are economic and torsionally stiff shaft connections suitable for a positive torque transmission. They ensure the flexible compensation of shaft misalignments as well. The gear coupling is made of high tensile steel with grease lubrication and O-ring seal. ear couplings C-ECO are used in all areas of mechanical engineering and offer a long service life with maximum reliability, resulting from the optimal grease lubrication of the crowned spline. The couplings are generally suitable for a horizontal assembly. pecial types are suitable for vertical assembly, too. The range of gear couplings ECO includes standard sizes from 52 to 280 with torque transmissions from 1900 Nm to Nm, these are suitable for shaft diameters from 20 to 280. Bigger shaft diameters and higher torques are possible on request.

Result: T KN x T x T AN > The coupling must be selected with a nominal torque T KN higher than the calculated value. Furthermore must be checked that the peak torque of the application is lower than the max. torque T Kmax of the coupling. Torque transfer regarding angular misalignment and rotational speed acc. to diagram page 6 must be checked. > In case that bigger shock or changing loads occur we recoend a revision according to DIN 740. An adequate calculation program is available. For such a revision the following information is required: 1. Kind of the driving machine 2. Kind of the driven machine 3. Power of driving and driven machines 4. Rotational speed of operation 5. hock loads 6. Exciting loads 7. oments of inertia of load- and driving sides 8. tarts per hour 9.
