Definitions

  • the invention relates to a wheel, in particular to a belt wheel for weft insertion on a weaving machine, consisting of a wheel hub and a wheel body operatively connected to it.
  • an oscillating belt wheel for weft insertion on a weaving machine, which has a wheel hub and a wheel body formed from a plurality of cells arranged parallel to the wheel axis as a honeycomb structure, which is closed on both sides by a circular plate and with the wheel hub is operatively connected.
  • the stiffness required for modern high-performance weaving machines is not sufficiently guaranteed with the belt wheel described above.
  • the wheel body is divided into a first wheel disk with an end wall and a second wheel disk with an end wall in the region of a radial connecting plane lying on the axial width, and in that the end walls are distributed in circumferentially and correspondingly arranged first spoke parts and the second spoke parts are divided, of which the second spoke parts each have a pocket-like inward wall and an essentially intersecting wall structure on the connecting plane, the walls being operatively connected to one another via wall sections distributed around the circumference in the form of circular cutouts.
  • the band wheel according to the invention can be produced from a material, for example from glass fiber reinforced plastic, which has a low specific weight (density), as a result of which a low moment of inertia is achieved. This improves both the lateral load capacity and the manufacture of the belt wheel.
  • the band wheel 50 essentially comprises a first wheel disk 2, a wheel hub 10 and a second wheel disk 12 (not visible in FIG. 1), the two wheel disks 2, 12 forming a wheel body 1 and being operatively connected to the wheel hub 10 in a manner not shown.
  • the wheel hub 10 is made of metal, preferably of light metal.
  • the two wheel disks 2, 12 are made of suitable plastic, for example of glass fiber reinforced plastic in the pressing, vacuum, deep-drawing process or the like.
  • the first wheel disk 2 has an outer wheel rim 6, an inner ring disk 7 and is further provided with first spoke parts 3 and second spoke parts 5 which are distributed around the circumference and connect the parts 6, 7.
  • a fastening part 25 which is designed to introduce force, is provided for a weft insertion band (not shown).
  • the band wheel 50 in a side view and one can see the first wheel disk 2, for example the band wheel front side with the spoke parts 3 inclined towards the second wheel disk 12, and the second wheel disk forming the essentially flat band wheel rear side 12.
  • a tread profile 26 for the weft insertion band which is fastened by means not shown, is arranged and fastened.
  • FIG 3 shows the wheel disk 12 forming the rear side of the band wheel 50, which is also provided with first spoke parts 13 and second spoke parts 15 arranged distributed around the circumference.
  • the fastening part 25 ′ designed as a counterpart is arranged corresponding to the part 25 of the wheel disc 2.
  • the first wheel disc 2 shown in profile cross-section in FIG. 4 has the wheel rim 6, which is designed as an outer collar, and an inner collar 7 ".
  • the parts 6 and 7" are formed in the region of the spoke parts 5 by one of several sections 7 ', 6 "and 6' Wall 8 and in the region of the spoke parts 3 connected to each other by an end wall 4.
  • the wall 8 comprises the conically shaped annular disk 7, the conical section 7 ', the section 6 "oriented largely perpendicularly or else inclined to the axis of rotation and symmetry X, and that conical section 6 '.
  • On the wall 8 for the spoke parts 5 formed essentially from the sections 7 ', 6 ", 6', corresponding side walls 4 ', 4" are formed, as shown in Fig. 1, seen in the circumferential direction, which are attached to the conical end wall Connect 4 of the spoke parts 3.
  • the spoke parts 3 are designed pocket-like on the inner side facing the wheel hub 10 and the spoke parts 5 on the opposite outer side.
  • the wheel hub 10 also shown in FIG. 4 in profile cross section is provided with a first flange 9 with a conical contact surface 9 'and with a second flange 11 with a contact surface 11' oriented perpendicular to the axis of rotation X and with recesses 10 ', 10 ".
  • the second wheel disc 12 shown in profile cross-section has the wheel rim 16 designed as an outer collar and an inner collar 17 ".
  • the parts 16, 17" are in the area of the spoke parts 15 by a wall formed from several part pieces 17, 17 ', 16 "and 16' 18 and connected to one another in the region of the spoke parts 13 by an end wall 14.
  • the wall 18 comprises the annular disk 17 oriented perpendicular to the axis of rotation X, the conical section 17 ', the section 16 "arranged perpendicular to the axis of rotation X and the conical section 16'.
  • the pieces 18, 16 ', 16' formed from the part wall 18 of the spoke parts 15 are, as shown in Fig.
  • spoke parts 15 of the second wheel disc 12 are pocket-like on the outer side, while the spoke parts 13 are formed by the end wall 14 as an end face oriented perpendicular to the axis of rotation X and distributed around the circumference in a segment-like manner.
  • FIG. 5 shows in cross section the entire band wheel 50 (without part 26) and the wheel body 1 formed from the first and second wheel disks 2, 12 and the wheel hub 10 can be seen.
  • the two wheel disks 2, 12 are on the outer wheel rims 6.16 and also operatively connected to one another in a connection plane denoted by VE on the segmental and area-like wall sections 6 ", 16" which are distributed around the circumference and each form a connection point VS.
  • the first wheel disc 2 is operatively connected to the inner collar 7 ′′ and the second wheel disc 12 to the inner collar 17 ′′ to the wheel hub 10. As shown in FIG.
  • the two wheel disks 2, 12 form an annular space 20 which is divided into an outer annular space 22 and an inner annular space 21 in the area of the spoke parts 5, 15 by the connecting points VS distributed around the circumference.
  • the wheel disks 2, 12 and the wheel hub 10 are connected by a suitable connection method, for example by an adhesive connection to the elements 6, 16; 6 “, 16" and 10 ', 17 “and 10", 7 "operatively connected to each other.
  • the walls of the individual spoke parts 5, 15 (FIGS. 1, 3) (FIG. 1, 3) which are firmly connected to one another by means of the wall sections 6 ", 16" form an essentially intersecting one in the connection plane VE Wall structure, whereby an increased rigidity of the band wheel 50 is achieved and the asymmetrical shape of the first wheel disk 2 is further increased by the preferred conical design and with respect to the connection plane VE.
  • the belt wheel 50 described above with the back arranged flat and perpendicular to the axis of rotation X (FIG. 2) has the advantage of space-saving arrangement on the weaving machine, not shown in detail.
  • the wheel body 1 comprises either two wheel disks 2 or wheel disks 12, which are operatively connected to one another at the connection points VS.
  • the wheel described with the spoke parts evenly distributed around the circumference and with an essentially crossing wall structure, has a relatively high degree of rigidity and is almost insensitive to transverse forces.
  • the area of application is therefore not only limited to a belt wheel for weft insertion on a weaving machine.
