Abstract

2.1. EL PROBLEMA DE LA INVENCION ES CONSEGUIR UN EQUIPO DE COMPENSACION, QUE ASEGURE MEDIOS SENCILLOS TECNICOS, QUE TRANSMITAN EN TODOS LOS PERNOS DE PRESION LA MISMA FUERZA, QUE ES REPRODUCIBLE DE ACUERDO CON EL EFECTO DE FUERZA DE LOS CILINDROS DE DESPLAZAMIENTO CORTO, UNO DEBAJO DE OTRO, PARA LA OBTENCION DEL CIERRE DE FUERZA COMPLETO ENTRE LOS ELEMENTOS DE FUNCIONAMIENTO DE FORMA EXCLUSIVA Y CON ELLO SE OBTENGA LA DISPOSICION DE SOPORTE ADECUADA DE TODOS LOS PERNOS DE PRESION. A PARTIR DE ESTO SE MUEVEN TODOS LOS PERNOS DE PRESION BAJO CARGA EN LA MISMA DISPOSICION DE RECALCADO. A CONTINUACION SE REALIZA UNA DISPOSICION DE COMPENSACION DE ACUERDO CON LAS CONDICIONES, QUE COMPENSAN LAS DESVIACIONES GEOMETRICAS EN LOS ELEMENTOS DE FUNCIONAMIENTO QUE SE ENCUENTRAN EN EL FLUJO DE FUERZA. 2.3. EN ESTE EQUIPO DE COMPENSACION LONGITUDINAL SE UNEN DE FORMA ACTIVA LOS CILINDROS (5) DE DESPLAZAMIENTO CORTO EN EL LADO MEDIO DE PRESION CON UN CILINDRO (10) DE COMPENSACION DE TAL MODO, QUE EL MEDIOA PRESION QUE SE DESPLAZA PARA EL COMIENZO DE TRACCION MEDIANTE EFECTO DE FUERZA EN LOS PERNOS (7) DE PRESION A TRAVES DEL DESPLAZAMIENTO (9) EN EL CILINDRO (5) DE CARRERA CORTA SE REALIZAN EN EL ESPACIO (2) DE COMPENSACION DEL CILINDRO (10) DE COMPENSACION.2.1. THE PROBLEM OF THE INVENTION IS TO OBTAIN A COMPENSATION TEAM, TO ENSURE SIMPLE TECHNICAL MEANS, THAT TRANSMIT THE SAME FORCE IN ALL THE PRESSURE BOLTS, WHICH IS REPRODUCIBLE IN ACCORDANCE WITH THE EFFECT OF DISPLACEMENT CYLINDERS. ANOTHER, TO OBTAIN THE COMPLETE FORCE CLOSURE BETWEEN THE OPERATING ELEMENTS EXCLUSIVELY AND THEREFORE OBTAIN THE SUITABLE SUPPORT PROVISION OF ALL THE PRESSURE BOLTS. FROM THIS, ALL PRESSURE BOLTS ARE MOVED UNDER LOAD IN THE SAME STANDING DISPOSITION. BELOW A COMPENSATION PROVISION IS MADE ACCORDING TO THE CONDITIONS, WHICH COMPENSATE THE GEOMETRIC DEVIATIONS IN THE OPERATING ELEMENTS THAT ARE FOUND IN THE FORCE FLOW. 2.3. IN THIS LONGITUDINAL COMPENSATION EQUIPMENT, THE SHORT DISPLACEMENT CYLINDERS (5) ON THE MIDDLE PRESSURE SIDE ARE ACTIVELY JOINED WITH A COMPENSATION CYLINDER (10) IN SUCH A WAY, THAT THE MEDIUM PRESSURE IS DISPLACED FOR THE BEGINNING OF TRACTION BY MEANS EFFECT OF FORCE ON THE PRESSURE BOLTS (7) THROUGH THE DISPLACEMENT (9) IN THE SHORT RUN CYLINDER (5) ARE MADE IN THE COMPENSATION SPACE (2) OF THE COMPENSATION CYLINDER (10).
