Definitions

  • the invention relates to a device for gear train separation according to the preamble of claim 1.
  • a device for gear train separation is from the German Patent 4 141 817 known.
  • this facility there is one annular unlocking device in the form of a hydraulic clutch to release the jamming between a main gear and provided a gear ring.
  • the hydraulic clutch acts Clamping devices that create the clamping by means of springs.
  • the facility has a relatively large volume.
  • Devices of this type are used, for example, in sheet-fed rotary printing machines used to convert to operating modes in to enable so-called straight printing or perfecting, the change being an adjustment of printing units relative to each other.
  • the aim of the invention is a device for gear train separation to make it more compact, which can be used as a structural unit.
  • the object of the invention is a device for gear train separation in a compact design with improved holding forces and to describe increased functional reliability.
  • the object is achieved according to the characterizing part of patent claim 1.
  • the advantage of the newly designed gear train separation device is the increased holding force of the device at the same time extreme compact design.
  • the facility is also able to separated part of the drive train when turning the other Drive train part to hold so that an additional brake is saved. Above all, support forces are no longer required into one of the gears to release the clamp. Through this mode of action, the accuracy of the Changeover increased further. These measures also increase the Functional safety of the facility is not insignificant. Further Advantages result from the features of the subclaims.
  • FIG. 1 an output gear 3 which is rotatable relative to this shaft journal 1 is shown on a shaft journal 1 which is connected to a drive gear 2.
  • a hydraulic coupling 4 is arranged on the end of the shaft journal 1 and is connected to a clamping device 5 for fastening the driven gear 3 on the shaft journal 1.
  • the hydraulic clutch 4 consists of an annular housing 7 and an annular piston 8 slidably mounted therein. Pressure medium can be fed into the annular space between the piston 8 and the housing 7.
  • the piston 8 is connected to a cover 9 which is fixed to the frame and is rotatably mounted on the end of the shaft journal 1 by means of a thrust bearing 6.
  • a gripping ring 10 is arranged on the housing 7 of the hydraulic clutch 4.
  • the gripping ring 10 is arranged with a button 10A opposite the clamping device 5.
  • the clamping device 5 consists of a flat, ring-shaped spring 11, a pressure ring 12, and an actuating ring 13.
  • the unit is of ring-shaped design and is placed on the shaft journal 1 so that it cannot move in the axial direction and is preloaded by means of the pressure bearing 6.
  • a series of bendable clamping elements 14 is arranged on the driven gear 3 facing the clamping device 5.
  • the clamping elements 14 rest on a clamping surface K on the shaft journal 1.
  • Spring 11 lying between the pressure ring 12 and the bendable clamping elements 14 generates a radial movement on the clamping elements 14 by axial movement of a switching element 15. 1 shows two variants for such switching elements 15 in the clamping device 5.
  • a switching element can be designed in the form of a packet of plate spring-like ring elements 15.1.
  • the switching element can be designed in the form of a single spring element 15.2 consisting of an annular, inclined wall.
  • the switching elements 15.1, 15.2 lie with the inside of their ring surfaces against a stop 16 on the driven gear 3.
  • the outside of the ring surfaces lies against a stop of the actuating ring 13.
  • the actuating ring 13 is moved away from the driven gear 3 by means of the hydraulic clutch 4.
  • the piston 8 is supported with a button 8A on the pressure ring 12 and the housing 10 with the button 10A on the actuating ring 13.
  • the switching elements 15.1, 15.2 are moved further in their inclined position.
  • the associated change in diameter on the switching elements 15.1, 15.2 releases or reduces the pressure on the clamping elements 14 relative to the shaft journal 1.
  • the force of the hydraulic clutch 4 is released, as a result of which the clamping elements 14 reconnect to the shaft journal 1 under the force of the spring 11 via the actuating ring 13 and the switching elements 15.1, 15.2 straighten up in the process.
  • FIG. 1 A comparable device is shown in FIG.
  • the clamping is generated by means of a wedge surface.
  • This is a Actuating ring 17 in the form of a ring with an inner conical surface 18 provided with a corresponding cone shape Outside surface of clamping elements 19 on the output gear 3 cooperates. These rest on a clamping surface K on the shaft journal 1.
  • the pretensioning is carried out by means of a wave-shaped spring arrangement 20 generated.
  • the biasing force of the spring 20 can be by means of the annular Hydraulic clutch 4 are canceled, which is the Clamping the driven gear 3 on the shaft journal 1 releases.
  • the two operating states are shown by way of example in FIG. 2.
  • the output gear 3 is clamped in the upper half of the figure, solved in the lower half of the picture.
  • the hydraulic clutch 4 fixed in the idle state on the cover 9 arranged, but held contact-free to the clamping device 5 is.
  • the switching state ie. when the two gears 2, 3, the buttons 8A, 10A are on the clamping device 5, increase their preload and relieve the actuation ring 17 or the clamping elements 19.
  • the shaft journal 1 firmly with the cover 9 and thus is also connected to the machine frame.
  • the drive gear 2 is blocked together with the coupled gear.
  • FIG. 3 shows a variant of the invention according to FIG. 1, where the preload of a conical actuation ring 21 opposite clamping elements 22 on the output gear 3 generated by a plate spring-like, annular spring 23 becomes.
  • the clamping elements 22 lie on a clamping surface K on Shaft journal 1 on.
  • the Selection is determined by the required spring characteristics.
  • the clamping of the driven gear 3 is by means of load the annular hydraulic clutch 4 on the plate spring 23 via the Pressure ring 24 and the actuating ring 21 canceled.
  • FIG. 4 A further variant can be seen in FIG. 4, wherein the locking of the output gear 3 with the shaft journal 1 via an axial acting fine tooth coupling 25 is generated.
  • the fine tooth coupling 25 is arranged in a ring on an actuating ring 26 and engages in a counterpart on the output gear 3.
  • the unlocking takes place through the annular hydraulic clutch 4 on the outside of the Actuation ring 26 by axial movement.
  • the fine toothing lifts 25 off, so that the driven gear 3 is freely rotatable.
  • clamping elements 14, 19, 22, 25th must be slotted at least in the axial direction in order to to be able to perform the required radial movement.
  • the clamping surface lying on the shaft journal 1 can ensure operational reliability K profiled, e.g. with a narrow groove. So that is the safety when switching the clamp through the escape of air guaranteed.
  • the output gear 3 to the drive gear 2 towards Have a groove in which a pin engages from the drive gear 2. This acts with a stop in the output gear 3 together to limit the maximum twist angle.
  • the device according to the descriptions described have overall an improved clamping of the driven gear 3 to be released with the shaft journal 1.
  • the clamping is due to the Arrangement directly on the shaft journal very compact and still points the necessary holding forces for the transmission of a high drive power on. Due to the reduced size are on the annular hydraulic clutch 4 very favorable conditions at the Sealing and when pressure medium is supplied.
  • the device is advantageous in sheet-fed rotary printing presses Bow turning can be used. Then it is used in particular become, if for space requirements or technological reasons for shifting drives between different intermediate gear levels with a smaller diameter next to the large main drive wheels be used.
  • the device represents the invention in a limited aspect and can also be carried out differently by interpreting the patent claim.
