Modular Electric Actuators OSP-E - Parker Hannifin GmbH - #17

Combined Loads If the actuator is subjected to several forces, loads and moments at the same time, the maximum load is calculated with the equation shown here. The maximum permissible loads must not be exceeded. Forces, loads and moments Fz Mz vj> Mx My' The total of the loads must not exceed >1 under any circumstances. M = F • l [Nm] M = M tti + M d i x x static x dynarmc M = M tti + M d i y y static y dynamic Mz = Mz static + Mz dynamic Fy The distance (lx, ly, lz) for calculation of moments relates to the centre axis of the actuator. Bending moments are calculated from the centre of the actuator and F indicates actual force. Maximum Permissible Unsupported Length - Placing of Profile mounting Fy Fz Maximum Permissible Unsupported Length Stroke Length The stroke lengths of the actuators are available in multiples of 1 mm up to 5700 mm. Other stroke lengths are available on request. The end of stroke must not be used as a mechanical stop. Allow an additional safety clear-ance at both ends equivalent to the linear move-ment of one revolution of the drive shaft, but at least 100 mm. The use of an AC motor with frequency converter normally requires a larger clearance than that required for servo systems. For advice, please contact your local Parker Origa technical support depart­ment. * For Bi-parting version the max. load (F) is the total load of both carriers — carrier 1 + carrier 2 k = Max. permissible distance between mountings/Profile Mounting for a given load F. When loadings are below or up to the curve in the graph below the deflection will be max. 0.01 % of distance k. k x Fz — k k Fz Fz Fy.«— Fy^ k Fz Fz Load F [N] 100000 -7-6 - 1 = BHD-20Fz 10000 2 = BHD-25Fz ! 3 = BHD-32Fz : 6 = BHD-50Fz 4 = BHD-20Fy 1000 - 5 = BHD-25Fy . 7 = BHD-32Fy 8 ;8 = BHD-50Fy 100 7 10 0 0,5 1,0 1,5 2,0 2,5 3,0 3,5 4,0 k [m] Max. distance 17
