Диагностика технического уровня силовых приводов клетей листовых станов горячей прокатки

Abstract

The problems of diagnosing the technical level of the actuators. proposed to estimate the total wear in all kinematic pairs involved in the transmission of torque from the electric motor to the work rolls stand, fixing backlash when reversing mechanical drive without load. Process the results of observations of change in torque on the shaft of the drive motor, which is directly connected to the gear shaft load gear finishing stand. In carrying out diagnostics of technical condition of actuators proposed to estimate the total wear in all kinematic pairs involved in the transmission of torque from the electric motor to the work rolls stand, fixing backlash when reversing mechanical drive without load. Provides a method of monitoring the change in the total clearance by the use of a laser device «Leica DISTO» A6. The method allows the residual life of the mechanical system.
