BED FOR DYNAMIC BALANCING OF WHEELS Russian patent published in 1995 - IPC

FIELD: instrumentation. SUBSTANCE: bed for dynamic balancing of wheels has base, bushing, spindle with balancing wheel coupled to bushing, two restoring elements. Each restoring element is produced in the form of torsion bar located in vertical plane perpendicular to axis of spindle. Intermediate element is fabricated in the form of two-side fork one end of which is coupled to base and the other one - to bushing via torsion bar. Deformation transducers of restoring elements are manufactured in the form of sensors of angular movement and are positioned at attachment points of torsion bars. Measurement circuit includes circuit of unbalance expansion along balancing plane, unit determining point of unbalance, clock pulse generator and two conversion channels. Circuit of unbalance expansion is connected with inputs to sensors of angular movements and with outputs to conversion channels and unit determining point of unbalance. Clock pulse generator is linked to velocity registration unit and information display. Pulse pickup is coupled to unit determining point of unbalance. EFFECT: enhanced operational efficiency. 4 cl, 5 dwg
