WEIGHING UNIT WITH FLEXIBLE GEAR MECHANISM ON ROLLERS IN BALANCE SYSTEM Russian patent published in 2009 - IPC G01G1/18 

FIELD: physics, measurement.

SUBSTANCE: invention relates to weight measuring equipment and is goaled for increasing reliability, fault-free operation, reparability during performance and reducing cost price. Weighing unit comprise a casing, a horizontal plate, arms, flexible elements, a counterbalance, a compensator and two rollers with their axes being placed in one horizontal plane. Each of the rollers can simultaneously roll one of its generatrices along guiding lines of two of four vertical casing poles and is supported by two of four flexible elements jointed to the poles. Second roller generatrix is rolling along the guiding line of two of four plate poles connected to the poles by two of four flexible elements; the platform is balanced by counterbalances on the arms which are fixed horizontally and oppositely in the rollers on one ends and which are fitted with cylindrical sectors linked by flexible elements and forming a hinge. In case the weighing unit is electronic it is equipped by compensators mounted at the arm and stops are set to limit the plate travelling.

EFFECT: increasing reliability, fault-free operation, reparability during performance and reducing cost price.
