Definitions

  • Such a transmission is known from European patent specification 0 035 954.
  • the change of the uniform rotary movement into a non-uniform rotary movement for the main shaft of the dobby is carried out by a stationary complementary cam, which rotates a rotor with a pivotable roller lever and cam rollers, which produce a positive connection to the complementary cam.
  • the roller lever undergoes a pivoting movement through the curve profile and this pivoting movement is transmitted to the main shaft of the dobby by means of a radially extending link guide on the roller lever.
  • One revolution of the rotor corresponds to two weaving machine cycles, so there is one weaving machine cycle per 180 ° curve segment. This ratio makes the cam segment partially concave and the cam roller diameter is limited.
  • the transmission designed according to the invention is arranged between the drive shaft (2) and the output shaft (3).
  • the drive shaft (2) and the output shaft (3) are rotatably mounted in alignment in the gear housing (1).
  • the rotor (4) is rotatably connected to it.
  • a sun gear (5) is connected to the gear housing (1) in a rotationally fixed and aligned manner with the drive shaft (2).
  • a planet gear (6) with a center (7), which is in meshing engagement with the sun gear (5), is rotatably mounted in the rotor (4).
  • the planet gear (6) has half the number of teeth from the sun gear (5), so that the planet gear (6) rotates a full revolution of 360 ° when the rotor (4) makes a half revolution of 180 °.

Abstract

Pour transformer un entraînement uniforme en une vitesse résultante non uniforme dans un engrenage, on a prévu dans l'engrènement une roue planétaire (6) tournant autour d'une roue solaire fixe (5). A la roue planétaire (6) correspond une came complémentaire (8) excentrique et solidaire en rotation avec elle. Le centre (9) de la came complémentaire (8) décrit une épicycloïde lorsque la roue planétaire (6) roule sur la roue solaire (5). Grâce au profil curviligne (10, 11) de la came complémentaire (8), un changement de mouvement superposé à l'épicycloïde est transmis par liaison de forme, par les galets de came (12, 13), à l'élément de l'engrenage (14) qui tourne. A partir de la valeur de la distance de la came complémentaire (E1) et de la forme du profil de came (10, 11), on peut déterminer les caractéristiques cinétiques de l'arbre mené (3).
