The importance o f this problem is increased by an order in terms o f unsteady loads (random, impulsive, alternating, etc.). The disad vantage o f its correct solution by experimental methods is substantially limited by the need for expensive and unreliable, environmentally dangerous current collectors. To measure the dynamic and kinematic parameters of the rotating transmission by modem information computer technologies, we propose equipping the mechanical transmission with two additional half-couplings with point magnets fixed thereon, the scope o f each includes one or more Hall sensors. The application o f the developed technique allows determining the torsional rigidity of the transmission experimentally, and allows recording the actual torque and capacity per turn (or a part o f the turn) o f the transmission of a process or transport machine and record the same online in the computer electronic memory. This, in turn, allows an online assessment of the residual transmission resource, machine operation per shift and generate its operation history, which provides an invaluable information both to the machine devel oper and owner.
