    • The invention relates to a regulation method for the hydraulic support of an electric drive. The force of an electric motor whose rotational movement is translated into a longitudinal movement via a transmission and the force of a piston of a hydraulic cylinder act upon an axially displaceable machine part in the longitudinal direction. The force exercised by the hydraulic motor is limited to a value at which the transmission is not yet damaged. In order to limit the force component supplied by the electric motor, a regulation difference is established from the desired value for the force acting upon the machine part in the axial direction and the actual value of said force. Said difference controls the sum of the force components acting upon the machine part in the axial direction. A desired value for the force acting upon the piston in the axial direction is established from the actual value of the force acting upon the machine part in the axial direction and a value that takes the mechanical stability of the transmission into account. A regulation difference is established from the desired value for the force acting upon the piston in the axial direction and its actual value. Said difference controls one of the force components acting upon the machine part in the axial direction.
    • 可轴向移动的机器部件中的电动机,其旋转运动通过齿轮被转换成纵向运动的力的纵向方向,和一个液压缸作用的活塞的力。 由电动机施加的力被限制为在该到齿轮箱没有损伤发生的值。 为了限制由电动机力分量施加的力从用于设定点值中的机器部件的作用力轴向方向和该力的实际值,用于控制作用于在轴向方向上的力分量的机器部件上的力的总和的控制差形成。 从在机器部件的作用力和传输值的机械负载能力的轴向方向上考虑的实际值,被形成在活塞上的轴向方向上作用的力的期望的值。 控制差从用于在活塞和其实际值,它控制作用于在轴向方向上的力分量的机器部件上的力的一个在轴向方向上作用的力的设定值来形成。
