CONVERTER OF ANGULAR DISPLACEMENTS OF THE SHAFT OF THE MECHANISM OF A TOWER CRANE Russian patent published in 2006 - IPC G01B11/00 

FIELD: the invention refers to measuring technique particular to devices providing possibility of measuring and registering of data about the work of the drive of a machine.

SUBSTANCE: the arrangement has a body in which the first shaft is installed with a driving element fixed on one of its end for interacting with the shaft of the mechanism of the drive of the crane and the first gear fastened on the other end of the first shaft , at that the other end of the second shaft is connected with the arrangement of registration of angular displacements of the shaft of the drive. The body has the first part, on which an arrangement of registering of angular displacements and the first shaft and jointly connected with the first part of the body its second part, in whose cavity the first and the second removable gears are located. The first and the second parts of the body form a L-shaped contour, in which deepening an arrangement for registration of angular displacement is placed. The gears of the first and the second shafts are located on constant distance between centers, the first and the second gears are fulfilled with possibility of increasing or reducing their diameters and cross-over relations between them. The first and the second gears, the first shaft and the driving element are fulfilled removable, the driving element is fulfilled with one radial groove under one of the turning element of the drive of the crane or with multitude radial grooves in it for multitude of turning elements of the drive of the crane.

EFFECT: increases universality of the arrangement, reduces expenditures for equipping the tower cranes with registering equipment.
