3 Features Toothing The coupling housings have a straight interna toothing whilst the hubs have an external toothing with a chased variable radius. As a result, the hubs can move spatially within the housing and thus compensate angular, radial and axial shaft misalignment of the adjoined shaft ends within specified tolerances. Depending on coupling type and size, the standard toothing permits an angular misalignment of up to 0.75 degrees per toothing-plane and an axial movement of several millimetres. The max. possible radial shaft displacement is dependent on the distance between the two too-thing planes. Other toothing geometries can be used for further specific applications. Materials High-grade tooth profiles and grease with ultra high-pressure additives guarantee low-restoring forces and a long service-able life. The material used is forged steel with an apparent yielding point of at least 350N/mm2. Special materials can be used for further specific applications. Sealing is carried out using O-rings and lip-seals of buna N. The housings are centred and held together by fitbolts and self-locking nuts. Temperature The use of special seals permits the temperature limit to be raised to 130 C. Balance At peripheral speeds upwards of 30 m/s it is advisable to dynamically balance the coupling. Special applications If greater misalignements are anticipated at higher speeds and torques, an exami-nation is necessary, performed with the assistance of a special computing programme. This is independent of thedetermined size. The valuetkmax may not be exceeded in any state of operation (start-up, electrical short circuit, blocking, etc.). Tolerances and standards The bore tolerance is ISO H7, if not differently ordered. The bore diameters listed refer to keyways to DIN 6885/1. 350N/mm2 O m/s ISO H7 DIN6885/1 4

4 General dimensioning Determination of the coupling size The POSIFLEX couplings are dimensioned on the basis of the impact torque. POSIFLEX (1) TAN = TN = 9550 PAN n TAN = Impact torque [Nm] PAN = Machine output [kw] n = Coupling speed [rpm] TAN PAN n = = = [Nm] [kw] [rpm] The nominal torque of the coupling must be equal to or greater than the impact torque, multiplied by the operating factor f: (2) TKN TN f T KN T N = Coupling torque = Impact torque in accordance with equation (1) f = Operating factor from table 1 [Nm] [Nm] [ ] T KN T N f = [Nm] = [Nm] = 1 [ ] With the torque and the technical specifi-cations you can determine the coupling size. Load from table 2 Operating factor f for drive mechanism f E-motor, turbine Hydraulic motor Combustion engine Uniform load Irreglular load 1,00 1,25 1,50 1,40 1,75 2,00 Heavy shock 1,80 2,20 2,50 Table 1: Operating factor f 5

Check whether the shaft diameters fit into the drilled holes of the hubs. Examine the torque transmission through the shaft-hub connection. Should standard hub lengths be inadequate, choose the extended universal hubs. Note the permissible coupling speed, particularly when considering whether dynamic balancing of the coupling is required for the operating speed. Speeds stated in the technical specifications of the types are permitted without special balancing. 11/98 6

6 General dimensioning Determination of the permitted angular misalignement For each size of the coupling reference data concerning torque and speed is fixed for determination of the permitted angular misalignement only (table 3). Table 3: Reference data Size Torque Speed ZEH ZEA/ZEB T Nref n ref [Nm] [Nm] [min 1 ] The permitted angular misalignement is a result of the comparison with the system data according to diagram 1.
