3 technology Reduction of costs! Reduction of components! Reduction of dimensions! Factors like cost reduction, material saving, simplified production processes, shorter delivery times of material are already determined by designing and development. Anyway, the growing demands can no longer be satisfied by keyway connections. In this case the use of CLAMPEX clamping elements offers new possibilities as a shaft-hub-connection: Material saving by smaller shaft and hub dimensions Simplified production processes Suitable for modern systems Easy assembly and disassembly with standard tools Ideal for s with high vibratory loads, e. g. acceleration and braking Produce connections that are permanently free from destruction, i. e. no shearing off of keyways, dowel pins, pins, etc. Specifically suitable for high-speed s Insensitive to dirt Reusable repeatedly Overload protection of the machine components by slipping (Repeated slipping should be avoided) Corrosion- and acid-resistant surface coating for food-processing industry, marine industry and chemical industry on request Simple calculation of the clamping connection CLAMPEX KTR Precision Joints Advice for selection: The transmission data mentioned in the catalogue are parameters found out by calculations. Subject to tests and the physical coefficient of friction slight deviations from the transmission values may arise. Copyright according to DIN We reserve the right for modifications of dimensions and designs. 09

4 KTR 0 Applications on hollow shafts, slip-on gears, couplings, mechanical shrink connections Suitable for high torque loads Easy assembly by optical mounting groove Corrosion-resistant outer ring (phosphatized) Good centering and concentricity characteristics Please find our detailed mounting instructions on our homepage ( Outer ring phosphatized and conus contact surfaces greased Inner ring greased Assembly Clean and degrease the contact surfaces of shaft and hub (internal hollow shaft). Slightly unscrew the clamping screws and put the clamping set externally onto the hub/hollow shaft. Before tightening the clamping screws please assemble the shaft. Evenly tighten the diametrically opposite clamping screws until the front surfaces of the outer and inner rings are flush. The max. screw tightening torque indicated must not be exceeded. The values for T and F ax indicated in the table relate to an assembly with greased external clamping set. The external clamping sets are delivered in greased condition. When assembling grease-free external clamping sets the values shown in the table and the values calculated are different. In case of questions, please feel free to contact us. Note: Contact surfaces of shaft and hub bore (internal hollow shaft) must not be greased or oiled. Disassembly All clamping screws must be unscrewed evenly and successively. Do not completely unscrew the clamping screws off the thread. Loosen the external taper ring in the inner ring with the forcing thread. Tolerances, surfaces One accurate turning process is sufficient: R Z 1µm Maximum permissible tolerances: d= f7 for the hub (external hollow shaft) d w = h/h7 d w > ø 10 - g/h7 Axial movement KTR 0: During the tightening of the screws there is no axial movement of the hub towards the shaft.

7 KTR 0 Typical external clamping set For middle and high loads Typical applications: hollow shafts, slip-on gears Please find our detailed mounting instructions on our homepage ( Assembly Clean and degrease the contact surfaces of shaft and hub (hollow shaft inside). Assemble the external clamping set onto the hub (hollow shaft outside). In the area of the external clamping set the external surface of the hub (hollow shaft outside) may be lubricated. Before tightening the clamping screws, assemble the shaft or push on the hub (hollow shaft). Tighten the clamping screws by degrees and evenly one after the other until the screw tightening torque T a mentioned in the table is achieved. Several tightening processes are necessary to achieve the requested T a figure. The figures T and F ax mentioned in the table were calculated for an assembly with oiled/greased external clamping set. The external clamping sets are delivered with oil/grease. For the assembly of external clamping sets without oil/grease the figures mentioned in the table will deviate. Please contact us for any questions you may have. Note: Do not use any oil with molybdenum sulphide between the contact surfaces of shaft and hub bore (hollow shaft inside). Disassembly Unscrew all clamping screws evenly one after the other. Do not fully unscrew the screws out of the thread. Usually the clamping elements release automatically.

Resulting torque T R The transmittable torque T T R always has to exceed the highest torque peak T B which may arise in the connection positions. The torque peaks arising during the acceleration of electric motors have to be considered. ] Fa d T T R T B + [ [Nm] Transmittable axial force F ax The maximum transmittable axial force F ax which is mentioned in the tables has to be reduced accordingly in case of additional torque transmission. F ax T = [KN] d Calculation of the outside diameter of the hub D N The required outside diameter of the hub D N depends on the cross section of the hub, the shape of the hub and the apparent yield point of the hub material. In order to facilitate the calculation the table on page 5 shows some figures by the help of which D N can be determined. Example: Shaft diameter d = 50 mm Hub material: GGG 0 Apparent yield point of material 0, = 50 N/mm Selected: CLAMPEX clamping set KTR100 with d x D = 50 mm x 80 mm and p N = 19 N/mm page 9 approximate value from table on page 5: pn = 150 N/mm selected design see page 5. C = 0, (value C of hub shape) figure as per table 1, D N = D x 1, = 80 mm x 1, = 11,8 mm Outside diameters of hubs which cannot be calculated based on the table are calculated with the following formula: N0, + p N C DN D N0, p N C For clamping connections with hollow shafts the required inside diameter of the hollow shaft diw is calculated with the following formula: d d W0, p W 0,8 iw W0, Tangential tension on the inside diameter of hub tin p N (1 + C N ) C [N/mm ] (1 C N ) Tangential tension on the inside diameter of shaft tiw p W [N/mm ] (C W 1) N0, = Apparent yield point of the hub material [N/mm ] C = Value C of hub shape (see picture on page 5) P N = Perm. surface pressure of clamping set/hub [N/mm ] D = Outside diameter of the clamping set T = Transmittable torque [Nm] T R = Resulting transmittable torque [Nm] T B = Operating torque to be transmitted [Nm] L/L 1 = Hub length W0, = Apparent yield point of the shaft material [N/mm ] P W = Perm. surface pressure of clamping set/shaft [N/mm ] d = Inside diameter of the clamping set C W = d iw / d C N = D / D N F a = Axial force arising during operation [N] F ax = Maximum transmittable axial force [N] = Prestressed force [N] F V
