Adjustable coupling for rigid connection of switch shafts - is for HV isolators or earthing switches and consists of tube with slots at ends

摘要

The ends of two switch shafts are coupled by a connecting tube (4). At both ends of this tube there are axially elongated, diametral, conically narrowing inwards holes (5), into which a clamping element (7) can be inserted. The clamping element is polygonal, conical and has an eccentric hole (6), through which a screw (6) passes, also passing through a switch shaft (9), so that by turning the clamping elements the angular position of the two switch shafts can be adjusted in steps corresponding to the number of their faces; axial adjustment of the shafts is also possible.
