Definitions

  • Such vane wheels generally comprise an outer toroidal surface, an inner toroidal surface and a plurality of vanes disposed between the toroidal surfaces.
  • vanes are most often secured by lugs to the toroidal surfaces in question, these surfaces being provided for this purpose with recesses or slots enabling the insertion of such lugs.
  • the inner toroidal surface to which the vanes are connected has the tendency to be angularly displaced relative to the associated outer toroidal surface.
  • a progressive deterioration of the connections of the vanes relative to the toroidal surfaces may result, and since the toroidal surfaces are in general connected only by the vanes, such deterioration may lead to irreparable damage to the vane wheels.
  • An aim of the present invention is the provision of a vane wheel capable of withstanding such effects.
  • the toroidal surfaces of such a vane wheel are rigidly connected to each other.
  • the vane wheel according to the invention for couplings or torque converters or the like comprises an outer toroidal surface, an inner toroidal surface, a plurality of vanes disposed between these surfaces, and anti-rotational bracing members provided from one toroidal surface to the other.
  • Such anti-rotational bracing members may be formed by simple plates obliquely arranged between the toroidal surfaces, by soldering, brazing, welding or simply embedding or propping, or by bars between the vanes fixed to the inner and outer toroidal surfaces, the said bars being connected or formed by a suitable extension of the inner toroidal surface or by a bend, for example, at right angles at the end of certain vanes, the bend being fixed to the inner and outer toroidal surfaces.
  • Such anti-rotational bracing members are of such a nature as to prevent any undesired rotation of the inner toroidal surface relative to the outer toroidal surface irrespective of the couple transmitted and the variations therein, and this substantially improves the life of the wheel.
  • FIG. 1 is a partial view in elevation of a vane wheel
  • FIG. 2 is a partial axial section taken along the line IIII in FIG. 1;
  • FIG. 3 is a partial view similar to FIG. I of an altemative embodiment
  • FIG. 4 is a partial view in section taken along the line IVIV in FIG. 3;
  • FIGS. 5 and 6 are views corresponding to FIGS. 3 and 4 concerning a further alternative embodiment
  • FIG. 7 is a view similar to that of FIGS. 1, 3 and 5 concerning another alternative embodiment
  • FIG. 8 is a partial view in section taken along the line VIII-VIII in FIG. 7;
  • FIGS. 9 and 10 are views similar to those of FIGS. 7 and 8 concerning still another embodiment
  • FIG. 11 is a view similar to that of FIG. 9 concemin yet another embodiment
  • FIG. 12 is a partial view similar to FIG. 1 concerning one more embodiment.
  • Such a wheel comprises in a known manner an outer toroidal surface 10, an inner toroidal surface 11 and a plurality of vanes 12 disposed substantially radially between these toroidal surfaces.
  • the vanes 12 are planar plates with lugs 13 along their outer curved surface to be inserted in complementary openings 14 formed for this purpose in the outer toroidal surface 10, and along their inner cuved surface lugs 15 are provided to extend through slits 16 formed for this purpose in the inner toroidal surface 11 andbent over this surface.
  • Anti-rotational bracing members are disposed between the toroidal surfaces 10 and 11.
  • plates 20 are arranged obliquely from an angular zone or comer 21 formed by the outer toroidal surface 10 and a vane 12 to an angular zone or corner 22 formed by the inner toroidal surface 11 and the vane immediately adjacent to the first mentioned vane.
  • the plates 20 are associated in pairs, the plates of a pair being disposed obliquely and substantially symmetrically about an intermediate vane 12.
  • Such pairs of plates 20 are preferably disposed along the portion of the toroidal surface 11 having the largest diameter and regularly distributed about the centre of the wheel for example every In the embodiment illustrated in FIGS. 1 and 2, the plates 20 are fixed by welding or soldering to the toroidal surfaces 10,11. Instead, the plates may be simply force-fitted between the angular zones 21 and 22.
  • the plates obliquely arranged are formed by sections of a single strip 25 having spaced apart bends 26 of alternating orientations.
  • These bends 26 are received alternately in grooves or slots 27 in the outer toroidal surface 10 and in the grooves or slots 28 in the inner toroidal surface 11 in line with the vanes 12 between these vanes and the toroidal surfaces; these receiving portions 27,28 may be formed by machining or upsetting.
  • Such obliquely arranged plates 20 provide by a propping action and/or rigidification a robust means for preventing relative rotation of the toroidal surfaces relative to each other.
  • anti-rotational bracing members are formed by right-angle bent portions at the ends of certain vanes 12 and the fixing to the toroidal surfaces 10,11 of the bent portions thus formed.
  • bent portions 30 are advantageously forcefitted between the toroidal surfaces 10, 11 taking into account the fact that their radial development at their free end is greater than their radial development at their bending zone.
  • the weding of the bent portions at the time of their engagement between the toroidal surfaces may be sufficient, and their fixing to the toroidal surfaces may be eliminated, in which case these bent portions are preferably formed two at a time in opposite directions.
  • bent portions 30 are formed facing one another on two adjacent vanes 12 and are connected by a bar 35 which is fixed to the bent portions and to the toroidal surfaces 10, 11 by welding, brazing or soldering.
  • Such a bar 35 is preferably provided with perforations 36 for the flow of fluid between the vanes 12.
  • the anti-rotational bracing members comprise bars 37 which are U-shaped in the radial plane of the wheel and are fixed along their lateral sides to toroidal surfaces 10, 11 between the vanes 12.
  • the bars extend from one vane to another and as in the case of the embodiment of FIGS. 5 and 6 are perforate. These bars may, however, stop short of the vanes themselves.
  • the concave surface of the bars face outwardly relative to the wheel; the concave surface could, however, face inwardly.
  • the bracing members are formed by radial extensions of the inner toroidal surface 11.
  • extensions 38 and 39 of the inner toroidal surface 11 are fixed at one of their ends to the outer toroidal surface 10 by soldering, welding, brazing or the like. These extensions are preferably perforate.
  • the present invention is, of course, not limited to the embodiments illustrated and described but encompasses all possible arrangements and equivalents.
  • a vane wheel for a fluid machine comprising an inner toroidal surface member, an outer toroidal surface member, a plurality of discrete independent thin flexible vanes of constant thickness extending substantially radially and perpendicular to said toroidal surface members, each vane being secured to each of said toroidal surface members, anti-rotational bracing members disposed between the toroidal surface members and extending circumferentially from one of said toroidal surface members to the other at least along a plane perpendicular to the axis common to said toroidal surface members whereby said anti-rotational bracing members resist in compression any tendency of relative rotational movement of the toroidal surface members.
  • bracing members comprise plates disposed obliquely between an angular zone formed by one of the toroidal surface members and a vane, and an angular zone formed by the other of the toroidal surface members and a vane immediately adjacent to the first-mentioned vane.
  • each plate is associated with another similar, obliquely arranged plate forming a pair of plates symmetrically arranged about the vane therebetween.
  • each plate is fastened to at least one of the toroidal surface members.
  • each plate is force-fitted in the angular zones.
  • each plate is part of a strip with spaced apart bends alternately received between the outer toroidal surface and a vane and the inner toroidal portions and an adjacent vane.
  • each plate has a curved surface.
  • bracing members comprise bent vane end portions.
  • a vane wheel according to claim 8 wherein the bent vane end portions are fixed to the toroidal surface members.
  • a vane wheel according to claim 8 wherein the bent vane end portions are grouped in pairs and forcefitted between the opposed toroidal surface members.
  • a vane wheel according to claim 1, wherein the anti-rotational bracing members comprise bars joined to the toroidal surfaces between two vanes.
