Technical instructions for application Speed Checking the critical torsional speed The plant or vehicle manufacturer has to prevent the use of driveshafts within the critical torsional speed ranges of the drive. Therefore, the determination of the critical torsional speed ranges of the drive system is required. The values for the moment of inertia and torsional stiffness of the selected driveshaft can be taken from the data sheets or be supplied upon request. Checking the critical bending speed Except for short and rigid designs, driveshafts are flexible units with critical bending speeds and flexural vibrations that have to be checked. To accomplish this, the first and possibly second order critical bending speeds are important. For safety reasons, the maximum permissible operating speed must be at a sufficient distance from the critical bending speed. The diameter is limited because of the ratio to the shaft size. Therefore, single driveshafts can only be provided up to a certain length. All installations exceeding this limit have to be equipped with subdivided drive lines. For determination of the critical bending speed, see the following selection diagrams. These diagrams only apply to driveshafts that are installed with solid bearing supports located close to the flange. Different installations (e.g., units with elastic mounting bearing) must have lower critical bending speeds. Depending on the type of the plant, excitations of second order can cause flexible vibrations. Please contact Dana engineers if the deflection angle exceeds 3° and for greater length dimensions. n perm. max. _~ 0,8 · n crit. [rpm] The critical bending speed for a particular shaft size is determined by the length and the tube diameter only (see diagram). For greater length dimensions, the tube diameter has to be increased. 41 © Spicer Gelenkwellenbau GmbH
