Rigid coupling: locking assembly
WMH Herion
medium-high torque
wide tolerances
Tolerances, surface fnish:
maximum allowable surface fnish:
Rt max 16µm (Ra 3 µm - Rz 13 µm)
shaft tolerance = h 11; hub tolerance = H 11
Centering:
Such a system is not selfcentering and therefore the concentricity of the piece to be fastened depends on the working tolerances between shaft and hub as we as the width of the centering guide.
Axial movement:
During screws tightening the hub has no axial movement with respect to the shaft.
