Determination of Actuator and Electric Drives Efficient Parameters of Lifting Devices

摘要

The methods of efficient parameters multifactorial determination of springy gears and electric drives of loads vertical traverse by the balanced manipulators are developed. The complex approach of power circuit choice of electromechanical force compensating systems taking into account the minimization of the mass, applicability of a nonreversible motor and operate with a low value of the maximum torques, active limitation of dynamic efforts in springy elements of mechanics using an electric drive and other factors allowing to improve the design of electromechanical systems of a special lifting device, industrial manipulators and robots, simulator complexes and testing workbenches is offered. The choice of the reduction radius desired value of the gear from following allowable value is recommended with the application of two approaches: an optimum setting using minimization criterion of the total maximum motor torque and a compromise derivative of efficient value of reduction radius satisfying to performance of all considered conditions. The method of rational parameter multifactorial determination of mechanical gears and a permanent-magnet synchronous electric motor for the load vertical movement system of a force compensating handling mechanism is offered.
