ABSTRACT:
A sliding weight scale includes a recirculating ball spindle mounted in a balance beam arranged to pivot about a swivel axis. The spindle extends perpendicularly of the swivel axis. A sliding weight is engaged via a nut with the spindle. A gear wheel is fixed to the spindle and is driven by another gear wheel fixed on the base plate of the scale. A hand wheel drives an intermediate gear assembly which, in turn, drives the gear wheels and the spindle. The gear wheels driving the spindle are located in a vertical plane containing the swivel axis of the balance beam. By the use of the recirculating ball spindle, the displacement forces acting on the sliding weight are kept small so that dimensional variations occurring in manufacturing and assembly have a negligible effect on the weighing accuracy of the scale.
