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 known from German Patent 4 141 817.
  • an annular unlocking device is provided in the form of a hydraulic clutch to release the clamping between a main gear and a gear ring.
  • the hydraulic coupling acts on tensioning 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 presses in order to enable a changeover for operating modes in so-called straight printing or face and back printing, the changeover requiring an adjustment of printing units relative to one another.
  • the aim of the invention is to make a device for gear train separation more compact, which can be used as a structural unit.
  • the object of the invention is to describe a device for gear train separation in a compact design with improved holding forces and increased functional reliability.
  • the object is achieved according to the characterizing part of patent claim 1.
  • the advantage of the newly designed device for gear train separation is the increased holding force of the device with an extremely compact design.
  • the facility is also able to separate part of the drive train to hold the rotation of the other drive train part, so that an additional brake is saved. Above all, it is no longer necessary to introduce supporting forces into one of the gearwheels in order to release the clamping. This mode of action further increases the accuracy during the changeover. In addition, these measures not insignificantly increase the functional reliability of the facility. 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 5 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 which is connected by means of a Thrust bearing 6 is rotatably mounted on the end of the shaft journal 1.
  • 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 actuation 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 presses the clamping elements 14 against the shaft journal 1 or decreased.
  • 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.
  • an actuating ring 17 in the form of a ring is provided with an inner conical surface 18 which cooperates with an outer surface of clamping elements 19 on the driven gear 3 provided in a corresponding conical shape. These rest on a clamping surface K on the shaft journal 1.
  • the preload is generated by means of a wave-shaped spring arrangement 20.
  • the biasing force of the spring 20 can be canceled by means of the annular hydraulic clutch 4, whereby the clamping of the driven gear 3 on the shaft journal 1 is released.
  • the two operating states are shown as examples in FIG. 2.
  • the output gear 3 is clamped in the upper half of the picture and released in the lower half of the picture.
  • the hydraulic clutch 4 is arranged stationary on the cover 9 in the idle state, but is held contact-free to the clamping device 5.
  • the buttons 8A, 10A rest on the clamping device 5, increase their pretension and thereby relieve the actuating ring 17 or the clamping elements 19.
  • the shaft journal 1 is fixed in this state is connected to the lid 9 and thus also 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, in which case the preload of a conical actuating ring 21 is generated with respect to the clamping elements 22 on the driven gear 3 by means of an annular spring 23 in the form of a plate spring.
  • the clamping elements 22 rest on a clamping surface K on the shaft journal 1.
  • a spring assembly consisting of two or more disc springs 23, also in different orientations with respect to one another, can be used. The selection is determined by the required spring characteristics.
  • the clamping of the driven gear 3 is released by loading by means of the annular hydraulic clutch 4 on the plate spring 23 via the pressure ring 24 and the actuating ring 21.
  • FIG. 4 A further variant can be seen in FIG. 4, the locking of the driven gear 3 with the shaft journal 1 being produced via an axially acting fine tooth coupling 25.
  • the fine tooth coupling 25 is arranged in a ring on an actuating ring 26 and engages in a counterpart on the driven gear 3. Unlocking takes place through the annular hydraulic clutch 4 on the outside of the actuating ring 26 by axial movement. The fine toothing 25 lifts out, so that the driven gear 3 is freely rotatable.
  • the clamping elements 14, 19, 22, 25 must be slotted at least in the axial direction in order to be able to carry out the required radial movement.
  • the clamping surface K lying on the shaft journal 1 can be profiled, e.g. with a narrow groove. This ensures the safety when switching the clamp through the escape of air.
  • the driven gear 3 can have a groove toward the drive gear 2, into which a pin engages from the drive gear 2. This interacts with a stop in the output gear 3 in order to limit the maximum angle of rotation.
  • the device according to the illustrations described have an overall improved clamping of the driven gear 3 to be released with the shaft journal 1.
  • the clamping is very compact due to the arrangement directly on the shaft journal and still has the necessary holding forces for the transmission of a high drive power. Due to the reduced size, there are very favorable conditions on the annular hydraulic clutch 4 Sealing and when pressure medium is supplied.
  • the device can advantageously be used in sheet-fed rotary printing machines with sheet turning.
  • it will be used if intermediate gears with a smaller diameter are used in addition to the large main drive gears for space requirements or technological reasons for shifting the drive between different levels.
  • the device represents the invention in a limited aspect and can also be carried out differently by interpreting the patent claim.
