5 CLAMPEX Selection guide Selection guide for CLAMPEX clamping elements Internal clamping sets Positioned between shaft and hub. Frictional engagement is generated between internal clamping set and shaft and between internal clamping set and hub. External clamping sets Positioned on the hub/hollow shaft. Frictional engagement is generated between shaft and hub/hollow shaft. Shaft couplings Positioned on two opposing shaft ends. Frictional engagement is generated between shaft coupling and shaft ends. hub Shaft Hub/ hollow shaft Shaft Shaft 1 Shaft Selbstzentrierend Shaft and hub are centered to each other via an internal clamping set. Additional hub centering is not required. Not self-centering Centering between shaft and hub required. Centering 1 2 With axial shifting of hub Axial shifting of hub during assembly of the internal clamping set. Hub axially shiftable to meet the catalogue data is required. Without axial shifting of hub No axial shifting of hub during assembly of the internal clamping set. Hub is fixed via the internal clamping set during assembly. before assembly before assembly after assembly, hub axially shifted after assembly, no axial shifting of hub Selection of the series of clamping elements based on its geometry and performance data Selection of the series of clamping elements based on its geometry and performance data Selection of the series of clamping elements based on its geometry and performance data Selection of the series of clamping elements based on its geometry and performance data Selection of the series of clamping elements based on its geometry and performance data KTR 105 KTR 130 KTR 131 KTR 200 KTR 203 KTR 400 KTR 201 KTR 206 KTR 225 KTR 250 KTR 100 KTR 150 KTR 603 KTR 620 KTR 700 Does not apply for KTR

Subject to the friction coefficient variation which is due to physical properties, small deviations with the transmission figures may appear. 1. Fatigue strength and shape stability of components subject to torsion and bending load The stress concentration figures βk for the clamping elements are worked out similar to those of hydraulic fittings. Stress concentration factor on request. 2. Transmittable torque T The transmittable torque T always has to be above the biggest torque peak TS, which may arise on the joints. The torque peaks occuring with acceleration of electric motors as well as additional axial forces Fa have to be considered. T TS [Nm] 2 + ( Fa [kn] d [mm] 2 ) 2 3. Transmittable axial force Fax The maximum transmittable axial force Fax specified in the tables has to be reduced accordingly with additional torque transmission. 4. Calculation of external diameter of hub DN The external diameter of hub DN required depends on the hub geometry, the yield point of the hub material and the surface pressure between clamping element and hub. In order to simplify the calculation, the table on page 265 specifies correcting values which allow to calculate DN. Fax [kn]= 2 T [Nm] d [mm] DN [mm] D correcting value x Clamping nuts Those external diameters of hubs which cannot be calculated based on the table are calculated via the following formula: DN D σn0.2 + PN C σn0.2 - PN C Tangential stress on the internal diameter of hub (1 + CN²) σtin PN (1 - CN²) C For clamping connections with hollow shafts the internal diameter of hollow shaft diw required is calculated via the following formula: diw d σw0.2-2 PW 0,8 σw0.2 Tangential stress on the internal diameter of shaft σtiw 2 PW (CW² - KTR Precision joints 267

7 CLAMPEX Example of calculation/selection Details given: Shaft diameter d: 50 mm Hub material: GGG 40 Yield point of material σ N/mm² Selected: Not self-centering internal clamping element KTR 100 with d x D = 50mm x 80mm Surface pressure of hub taken from table on page 271 P N = 132 N/mm 2 Approximate value for surface pressure of hub taken from table on page 269 P N = 135 N/mm 2 Hub type selected C=0.8 (value C of hub design see page 269) Yield point of material σ N/mm² Correcting values x 1.59 (see page 269) DN [mm] 80 mm 1,59 D N 127,2 mm Use in explosive locations The power transmission of CLAMPEX clamping elements is based on the principle of two taper rings twisted into each other. An axial force generated on the rings (by means of several screws) produces surface pressure inside the hub and outside the shaft which allows for a frictionally engaged transmission of the torque. Considering all operating data (intended use) a potenial source of ignition does not exist. That is why clamping elements are not covered by directive 94/9/EC. Due to the aforementioned design of CLAMPEX clamping elements a failure of components does not have to be expected. A risk only arises if friction heat is produced with slipping of a clamping connection (improper assembly/tightening torques). Concentricity The concentricity of the self-centering CLAMPEX clamping elements is between 0.02 mm and 0.08 mm. This concentricity is not reproducible due to the slotted individual components of the clamping elements. As a result this figure merely serves for supporting with designing.
