Spindle for a machine tool, and the development process of an amount of torque between the first and second members of a set of gears in a machine tool

摘要

"The spindle for a machine tool and development process of an amount of torque between the first and second members of a set of gears in a machine tool.The invention relates to a spindle (60) for a machine tool, comprising a portion of the rear zone (62), and a portion of the frontal zone (64).With each one of said portion of the spindle and the rear portion of the frontal zone being capable of being rotated around the same axis geometric one over the other.The inventive zone includes one or more elements of the spring (68) which extend between the rear spindle portion (62) and the portion of the frontal zone (64), and,With the portion of the frontal zone and the portion of the rear spindle rotating in a predetermined amount and with the rotation of the portion of the frontal zone is restricted to that amount.An additional rotation applied to the rear spindle portion results in a deflection of the springs, thus affecting the torque between the front and rear portions of the spindle.The present invention also includes a control process, which has as its aim to control the position of, not the torque applied to one of the spindles in the ` state of gear.In this process, the portion of the spindle of the state of gear is controlled in relation to the position of the spindle member of Jatropha for devices, such as computer numerical control (CNC).When the state of the pinion is rotated at some speed, the state of gear is kept in coordination with the pinion (according to their ratio) by means of the CNC control.The spindle member of gear can be actuated to include additional rotational components, which, in effect, advance or retard the rotation of the gear relative to the pinion.
