..4.1 Connecting Shaft VWZ Mounting Using split couplings the connecting shafts can be assembled after installation of the screw jack gearboxes. Mount the connection shaft onto the gearbox drive shaft and assemble the half coupling tightening the screws to the required torque (see table no keyway necessary). max. allowable axis offset Offset lateral Kr max. 1,5 mm per 0 mm LI Height adjustment Adjusting the height of the various screw jacks connected by VWZ connecting shafts is very quick and easy. Loosening one clamping hub and adjusting on one side allows very precise stepless movement. For example: With the standard gear reduction this means one 3 rotation is equivalent to 1 mm stroke, e.g. 3,6 = 0,01 mm stroke. When setting under load, one lifting system with several screw jacks can be positioned very accurately. Set screw tightening torque acc. to table Adjustment under load > 0,01mm Angle error max.

. flexible coupling rigid coupling VWZ with Rigid Coupling for Use with Pedestal Bearing In order to specify the correct shaft the method of assembly is very important. E.g. a larger diameter shaft which does not require additional support can be considerably lower cost than a smaller shaft requiring additional pedestal bearings and support fabrication. For this version we use the rigid coupling, so that no tangential deviation in the pedestal bearing is possible.
