Definitions

  • This invention concerns a high speed rolling block.
  • the invention concerns an improved rolling block of a type comprising units arranged alternately with axes perpendicular to each other, for instance with alternate horizontal axes and vertical axes.
  • a drive and motion-transmission system is employed for such units which is made simple to construct, has greater reliability than known embodiments and provides noteworthy constructional and running economies.
  • one or more motors transmit motion through a suitable transmission to two shafts the axes of which are parallel.
  • Traditional rolling blocks consist of a group of vertical units and a group of horizontal units, or else of units perpendicular to each other but otherwise oriented as required.
  • Each unit gets its motion from one or the other of the two shafts, according to the arrangement, through a bevel gear pair. In this way there is a bevel gear pair for each unit in a block, however such unit is oriented.
  • This embodiment contains many drawbacks, including:
  • the present invention is intended to obviate the above drawbacks and yet others and to offer a drive system which enables the bevel gear pairs and parallel shafts to be eliminated.
  • each motor is given an axis parallel to that of the units connected kinematically to that motor.
  • one of the motors may have its axis not parallel to the axis of the respective blocks. This may be made necessary, for instance, by overall bulk requirements or other specific requirements.
  • the motor having its axis not parallel to the axes of the group of units driven by it can transmit motion to that group through a transmission which includes, for example, an oblique shaft with bevel gear pairs at its ends.
  • the synchronization of the motors can be obtained through an electrical connection or through a mechanical connection.
  • the invention is thus embodied with a high speed rolling block which comprises two groups of units synchronized with each other, the units being arranged alternately, each with its axis perpendicular to the axis of the neighbouring unit, in which block each group of units is driven by an independent motive shaft substantially parallel to the axes of the units of the group thus driven.
  • the units 10 and 11 could be tilted as required and would therefore not be necessarily vertical and horizontal respectively provided that their respective axes were substantially perpendicular to each other.
  • the rolling axis is shown with 13.
  • Two electric motors 14 and 15 drive the units 10 having a vertical axis and units 11 having a horizontal axis respectively.
  • All the vertical units 10 are connected to each other kinematically by means of a train of spur gears having vertical axes, the train getting its motion from the output shaft of the motor 14.
  • Synchronization of the two groups of units 10 and 11 is obtained, instead, by synchronizing the motors 14 and 15.
  • Such synchronization may take place, for instance, through an electric axis 16, which is shown diagrammatically with lines of dashes in Fig.1.
  • each group of units 10 or 11 is driven by means of a motion input shaft, 20 or 25 respectively, parallel to the axis of rotation of each individual unit forming the group.
  • the motors 14 and 15 can be synchronized also by means of a mechanical connection.
  • Figs.2a and 2b there are still two motors 114 and 115 respectively which in this case have their axes 23 and 25 respectively shown as being parallel.
  • the positioning of the motors 114 and 115 according to the method shown may be determined, for instance, by considerations of overall bulk whenever it is not desired or is not possible to position the two motors 114-115 with their axes perpendicular to each other.
  • the motor 114 drives the units 10 having a vertical axis in the following way: a bevel gear pair 18 drives a shaft 19 having another bevel gear pair 118 at its other end; the bevel gear pair 118 transmits the motion about a vertical axis 20 to a kinematic distribution system 21 feeding motion to the units 10 having a vertical axis.
  • gearing up means can be included in correspondence with each unit, or else the gearing up or reduction gear means can be provided upstream from the unit, for instance in correspondence with the motion inputs on the axes 20 and 25 respectively.
  • the electrical synchronization 16 too can be disconnectible as required.
  • This may be determined, for instance, by special rolling requirements which necessitate the elimination of the coupling between the motors.
