Definitions

  • the invention relates to a drive device for working elements on weaving machines, a reversibly driven, fixed to the frame Drive wheel is a working element that runs parallel to the fabric stop edge drives, whereby for the reversible drive of the gen. drive wheel, whose axis is directed perpendicular to the tissue stop edge the main shaft of the weaving machine, which is directed parallel to the fabric stop edge at least one curve body is provided and the curves of the cam body can be scanned using roller levers and the generated in this way Swinging motion via an input shaft, first of all a highly translating one Gear and then the drive wheel is fed.
  • DE 33 25 591 C2 is a gear for driving gripper bars on looms, in which two on the Main shaft cam plates arranged parallel to each other interconnected pair of roller levers are positively scanned.
  • the oscillating shaft of the pair of roller levers also carries a segment that the Transfers swinging motion to the first gear of a gear train that with a multi-stage translation the changing drive movement for the gripper bar creates.
  • a disadvantage of this transmission is that the stroke movement z. B. for the gripper bar cannot be adjusted at any point.
  • a second, very essential The disadvantage is that there is an uncontrollable in the overall transmission Play and an uncontrollable elasticity is present, which only with high Storage expenses can be limited.
  • This drive device is therefore not suitable, a significant increase in speed the weaving machine with reliable operation of the designated To enable work items.
  • DE 43 37 406 A1 describes another transmission for driving a Pair of rapier rods on double carpet weaving machines.
  • the basic structure of the gearbox essentially corresponds to that with respect was described on DE 33 25 591 C2.
  • the transmission of the lifting movement from the oscillating shaft to the oscillating drive segment of the The gear train is carried out here with the help of a flat coupling, the joints the coupling on the respective rocker arms are adjustable.
  • a torsion spring is provided, which is to eliminate the play in the gear - starting with the roller gear up to the second gear stage - by means of an appropriately leading or trailing tensioning gear.
  • the axis direction in the gearbox is changed only by a bevel gear in the penultimate gear stage.
  • the torsion spring therefore has no effect on the compensation of the elasticity of the bevel gear. It also has no positive effects on the gear elements moving at high speed and with high acceleration. This gearbox is therefore not suitable for ensuring a further increase in the speed of the weaving machine.
  • the oscillating shaft drives for the purpose of translating the oscillating movement a cycloidal or planetary gear arranged coaxially to it.
  • the driven gear this cycloid or planetary gear is as a toothed belt pulley trained and drives the knife carriage via a very long toothed belt iridescent over the required, very large path parallel to the fabric stop edge.
  • the solution according to claim 1 has the advantage that the gear play in the spherical rod ends of the paddock - even after prolonged use - very much can be kept low.
  • the elasticity of the spherical paddock is clear lower than the elasticity of the conventional bevel gear stages.
  • the ones that can be designed as desired with the shape of the cam disks Laws of motion can be almost flawless right down to the work element translate.
  • the gear play and the elasticity of the gear are on reduced to a minimum.
  • the second basic embodiment according to claim 2 starts from the Use of other curve systems.
  • the cylinder and globoid curves enable the oscillation movement to be generated directly on the shaft, which is already perpendicular to the main shaft.
  • the application of a elastic bevel gear stage is avoided.
  • the achievable advantages correspond to those of claim 1.
  • the solution variant according to claim 3 ensures the use of a Screw gear for changing the direction of the swinging motion. Also this screw gear ensures the safety with minimal play a low elasticity of the gear.
  • the end exclusively about Helical gear pairings can be very strongly translated swinging motion high working speeds with high precision. Also here it is possible by using appropriate levers adjustable joints to ensure a change in stroke.
  • the design of the spherical coupling according to claim 8 has the advantage of Use of standardized assemblies and components.
  • the claim 9 defines the use of cycloid gears, in which the Power is transmitted through cams, which in turn are by means of eccentrics are driven.
  • the use of this gear has the advantage that you can can achieve very large gear ratios with one gear stage.
  • gearbox known as "Harmonic Drive” is capable of an extremely large gear ratio in a gear stage to realize.
  • a pair of cams 11 is arranged rotationally rigid.
  • a double roller lever 21 works with this pair of cams 11 in this way together that he is form-fitting with a swinging motion around the axis the oscillating shaft 2 is moved.
  • a rocker arm 26 is initially located on the rocker shaft 2 the oscillating shaft 2 rigidly connected. At the free end of the rocker arm 26 attacks a spherical paddle 30, which offset two by 90 ° to each other Possesses joints. Each of these joints is designed as a self-aligning bearing. In spherical roller bearings 301 are generally used for this configuration. Both axes of the joints are regularly transverse to the main direction of movement the spherical coupling 30 aligned.
  • the second joint of the spherical coupling 30 works with a drive lever 42 together on the input shaft 4 of the gear train 5.
  • the Gear 5 which is designed here as a planetary gear, drives the Input shaft 4 the web 51 on which planet gears 52 are mounted.
  • the Planet gears 52 roll on the inside of the toothing of the ring gear 53 and drive the sun gear 54 inside.
  • the sun gear 54 is torsionally rigid with the web 541 of a second planetary gear connected. This web 541 also guides planet wheels 55 which roll the internal toothing of the ring gear 56 and the sun gear 57 float.
  • the ring gear 56 is firmly anchored in the machine frame.
  • the last Sun gear 57 is rigidly connected to the output shaft 571, which on its upper end carries the drive wheel 6.
  • the drive wheel 6 drives in the present Case the gripper belt 61. However, it can also be used to drive a toothed belt be designed, which drives the knife carriage.
  • a vibration wave 2 is used further rocker arm 25 driven.
  • This rocker arm 25 is opposite directed to the rocker arm 26. It has one at its outer end second spherical coupling 31, which has a spherical joint with the Ring gear 53 is connected at 531.
  • the translation additionally enlarged in the first stage of the gear train 5.
  • connection of the double roller lever 21 and the rocker arm 25, 26 on the oscillating shaft 2 can be made very stable with known measures, so that there is no torsion and no deflection between these elements can occur.
  • the couplers 30 and 31 are only loaded under tension or pressure. You are in Gear train with regard to the elasticity of the gear as rigid. Will the input shaft and its connection to the web 51 and the drive lever 42 is very stable, then there are torsions and other deformations largely excluded. Also positioning options You can provide for changing the stroke size in this area.
  • the gripper belt 61 or the other respective working element carries a very large stroke movement even at very high working speeds least play out.
  • FIG. 3 A second variant of the drive is shown in Fig. 3. Instead of two different cams 11 drives the main shaft 1 of the Loom a cam 15 of the same diameter. Their lifting movement is positively through the cam rollers of a push rod 7 decreased.
  • This push rod 7 has at its upper end two plungers 71, 71 'which in frame-fixed guide rails 72, 72 'are guided. These plungers 71, 71 ' are equipped with drive rollers 711, 711 '. These engage in the groove of one Screw curve 431, which is attached to a cam cylinder 43.
  • the Curve cylinder 43 advantageously has two mutually offset by 180 ° Screw curves 431, the pitch angle of which is preferably greater than 45 °.
  • FIG. 4 shows the drive of the input shaft 4 'of Gear 5 directly above the roller lever 22, which is a cylinder curve 12 is positively moved swinging.
  • a bevel gear or complicated Measures to avoid torsion are used in this version avoided.
  • Fig. 6 shows a further variant for the replacement of the drive with cylinder curves 12 or with globoid curves 13 by cone curves 14, the drive a roller lever 24 in a form-fitting manner.
  • the drive for an oscillating movement of the roller lever 24 is only there possible where the shaft extension of the main shaft 1 is available.
  • Such gears are said to be very compact design ratios of 1: 119 can achieve.
  • the so-called “harmonic drive” gearbox has an all-round steel disc, on the circumference a flexible toothed ring with external teeth easily is rotatably guided.
  • This toothed ring runs in the area of the larger diameter on the internal toothing of a ring gear, which is a slight has a larger number of teeth than the toothed ring.
