Definitions

  • a stressing arrangement is provided for stressing the annular element axially so as to effect radial displacement of the annular wall portions into frictional engagement with the inner and outer member, respectively.
  • the stressing arrangement includes a pair of annular stressing members located at opposite axial sides of the annular element in the clearance and each having a side facing the annular element and provided with at least one annular bead projecting axially by a distance which is slightly greater than the distance by which the annular wall portions project beyond the transverse wall portion.
  • the invention relates to a connecting arrangement in general, and in particular to an arrangement for connecting two members one of which surrounds the other with annular clearance.
  • Such connecting arrangements are already known and are, for instance, employed for connecting a sleeve or a bushing with a shaft extending therethrough.
  • dished annular springs located in the clearance between the shaft and the bushing and which, when subjected to axial pressure and thereby to deformation from dished to planar condition, will engage the shaft and the bushing with the inner and outer edges, respectively.
  • the members must be weakened where they are provided with the grooves in which the key or the like can extend, and in the latter case the contact established by the inner and outer edges of the dished springs is merely a line contact and is frequently ineffective.
  • a further arrangement is discussed in my prior US. Pat. No. 3,578,364, in form of a connecting arrangement wherein one or several axially consecutive ring members are located in the clearance between the cylindrical inner member and the annular outer member.
  • These ring members located in this clearance and constituting the connecting means are in axial section of substantially Z-shaped or substantially Y-shaped configuration and, when subjected to axial stress, are spread radially into engagement with the opposite surfaces of the inner and outer member. This results in frictional engagement with these inner and outer members and in a strong connection thereof against movement relative to one another, because such connection is of course a surface-to-surface contact rather than a line contact.
  • a novel annular connecting element having an annular member of elastically yieldable material provided with a transverse annular portion of predetermined axial thickness and provided with oppositely directed axial faces.
  • An outer and an inner annular flange portion both project from one of these faces axially of the annular portion at an outer and inner margin thereof, respectively, and an axially projecting bead is provided on the other of the axial faces centrally thereof and has a radial thickness corresponding to at least substantially triple the thickness of the respective flange portion.
  • annular groove located centrally of the endface and opposite the bead, such groove having a depth which corresponds at least substantially to the predetermined axial thickness mentioned above.
  • Still another object of the invention is to provide such an arrangement in which an improved relationship of the axial force required for stressing the connecting arrangement is obtained, with reference to the holding force obtained when the arrangement is so stressed.
  • one feature of the invention resides in an arrangement of the type hereunder discussion which, when briefly stated, comprises a substantially cylindrical inner member having an outer circumferential surface and a longitudinal axis.
  • An annular outer member coaxially surrounds the inner member and has an inner circumferential surface defining with the outer circumferential surface an annular clearance.
  • Connecting means is received in this clearance for connecting the members against relative movement and includes at least one annular element of elastically yieldable material having a transverse wall portion extending transverse to the axis across the clearance, and an inner and an outer annular wall portion having spaced axial ends and extending in opposite directions axially of the clearance beyond the transverse wall portion by a predetermined distance.
  • the new arrangement also comprises stressing means operative for subjecting the annular element to axial stresses to thereby effect radial displacement of one of the axial ends relative to the other so that in the annular wall portions respectively frictionally engage these surfaces of the inner and outer members, the stressing means comprising a pair of annular stressing members located at opposite axial sides of the annular element and each having at a side facing the same at least one annular bead projecting axially by a distance slightly greater than the predetermined distance and cooperating with a respective one of the annular wall portions.
  • annular stressing members When the aforementioned annular stressing members are utilized with an annular element of substantially Z- shaped axial cross section, wherein the annular wall portions extend in opposite axial directions by identical distances, an improvement of the relationship between the stressing force acting in axial direction and the holding force obtained upon such stressing, is obtained. Furthermore, the concentric relationship of the outer annular member with respect to the connecting means is facilitated.
  • the connecting effectiveness of a Z-shaped annular element is further improved if it is provided on the opposite axial end faces with an inner and an outer annular ridge, respectively.
  • the inner annular ridge projects at the outer margin of the annular member on that side where the annular member is provided with an annular wall portion projecting from its inner margin, and the outer annular ridge projects from the other axial end in the reverse relationship, that is on the outer margin where an annular wall portion projects from the inner margin.
  • the axial extent to which these ridges project should be slightly greater than the extent to which the annular wall portions project, and if for instance two of the annular members are provided it is important that the outer diameter of the ridges with respect to the outer diameter of the annular wall portions be so selected that when an annular ridge of one of the annular members is located adjacent an annular wall portion of the other annular member, they will define a slight radial clearance with one another and will not contact.
  • annular wall 7 portions with recessed annular steps which are recessed from the respective axial ends of the annular wall portions and on which the respective stressing members rest, with the height of the steps and axial direction of the annular members being less than the height of the remainder of the annular wall portion in the same direction.
  • This further improves the relationship between the stressing force required and the holding force obtained, and it is advantageous if the annular wall portions in this case are slotted from their respective axial end over the entire height of the step so provided, with the slots again being approximately 1 millimeter wide and circumferentially spaced at angles of 6. This measure in particular affords the possibility of bridging larger-diameter differences than would otherwise be possible.
  • annular wall portions may be provided with annuli of teeth or similar projections which interengage with corresponding engaging portions on the outer circumferential surface of the inner member and the inner circumferential surface of the annular outer member, respectively.
  • FIG. 1 is an axial section of the right half of an arrangement according to the present invention, it being understood that the arrangement is annular and that the non-illustrated half is mirror-symmetrical with reference to the one which is shown;
  • FIG. 2 illustrates a further embodiment in a view analogous to FIG. 1, with the same comments concerning the mirror-symmetrical arrangement being applicable;
  • FIG. 3 is a view similar to FIG. 2, on an enlarged scale, illustrating a further embodiment of the invention and also with the same comments applicable as before;
  • FIG. 4 is a view similar to FIG. 3 illustrating still an additional embodiment
  • FIG. 5 is a view analogous to FIG. 4, but illustrating also the inner and outer members which are to be connected with one another and showing still another embodiment of the invention, it being again pointed out that the arrangement is annular and that the nonillustrated half is mirror-symmetrical with reference to the one shown;
  • FIG. 6 is a view similar to FIG. 1 but illustrating only a novel annular element according to the present invention
  • FIG. 7 is a view similar to FIG. 6 illustrating an additional novel annular element
  • FIG. 8 is a view similar to FIG. 7 illustrating another embodiment of the invention.
  • FIG. 9 is a top-plan view of FIG. 8.
  • FIG. 1 there is illustrated an annular member having a transverse wall portion 4 and an outer annular wall portion 3a projecting beyond one axial end of the transverse wall portion 4, as well as an annular wall portion 3b which projects beyond the opposite axial end of the wall portion 4; the portions 3a and 3b project from the portion 4 at the outer and inner margins thereof, respectively.
  • the member 3a, 3b, 4 will have an orientation which is exactly normal to the longitudinal axis of the shaft 8 (see FIG. 5).
  • a stressing member 6 which is also annular and which is provided in the region of its inner circumferential margin with an axially projecting annular bead 7.
  • the cross-sectional configuration of the bead 7 is the same as or analogous to that of the wall portions 3a and 3b, that is at one side it is flat and at the other side it is bounded by a surface which diverges in directions towards the transverse wall portion or route of irrespective wall portions 3a, 3b or bead 7.
  • the distance by which the bead 7 projects axially from the remainder of the annular member 6 is slightly more than that by which the annular wall portion 3b projects from the transverse wall portion 4, as evident from FIG. 1.
  • annular stressing member 6 Just as the annular stressing member 6 is superimposed upon the upper side of the annular element, so a second annular stressing member or a support member S is located beneath and juxtopposed with the underside of the annular element. It also has an annular bead which is identified with reference numeral 7a and which projects axially also by a distance which is slightly greater than that of the axial length of the wall portion 3a.
  • Reference numeral 10b identifies a bolt having a head 10a and extending through appropriate openings provided in the members 5 and 6 and the element 3a, 3b and 4, and when the bolt 10b is tightened (it could also cooperate at the side opposite the head 100 with a suitable nut bearing upon the member 5) axial stressing of the arrangement will take place.
  • the bolt 10 which extends through the openings not directly via bolt 10b which extends through the openings 15 but via the members 5 and 6, there will be no axial stress acting only upon the outer edges of the wall portions 3a and 3b, so that an even application of axial stress is obtained, and also radial friction is avoided. Because of this a much improved relationship between the required axial stress and the obtained holding force with respect to the members 9 and I0 is achieved (the former is lower and the latter is higher).
  • FIG. 2 I have illustrated at least two axially adjacent annular elements, each having the wall portions 3a, 3b and 4. Located between these elements there is provided an intermediate ring 16 having at its opposite axial ends projecting ribs 17 of annular outline, with one of these ribs 17 being associated with the wall portion 3a of one of the annular members (the upper one in FIG. 2) and the other rib 17 being associated with the wall portion 3b of the other annular element. Any axial height or length of the ribs 17 is slightly less than that of the wall portions 3a and 3b. In all other respects FIG. 2 corresponds to FIG. 1, and this includes the manner in which the axial tensioning force can be applied.
  • FIG. 3 I have shown an embodiment which is reminiscent of that of FIG. 2 except that the intermediate ring 16 of FIG. 2 is here replaced with two concentric rings 18 and 19.
  • the ring 18 has an axially projecting rib 20 and at the opposite axial side the ring 19 has a similar rib 20.
  • These ribs cooperate with the wall portions 3a of the one annular member and 3b of the other annular member, respectively, and also of slightly greater axial length than that of the wall portions 3a and 3b.
  • FIG. 4 it will be seen that here there are provided four of the annular elements each of which has the transverse wall portion 4 and the inner and outer annular wall portions 3a and 3b, respectively. It should be understood that fewer or more than four of these annular elements could be provided.
  • each of these annular elements is provided with an annular bead 21 located at one axial end (in FIG. 4 the one where the wall portion 3b projects) and an additional annular bead 22 located at the opposite axial end (in FIG. 4 the one where the wall portion 30 projects).
  • These axial pressure beads 21 and 22 have a height which is slightly less than the height or axial length of the wall portions 3a and 3b, and their overall diameter is so selected that between them and the cooperating wall portions 30 and 3b there will remain a slight radial clearance or gap 40, as illustrated, but which is small enough so that proper centering is assured.
  • the beads 23 and 24 of the two lowermost (in FIG. 4) annular elements are provided with axial slots, having a width of approximately one millimeter and being circumferentially offset at angles of about 6.
  • the members 5 and 6 are provided, but in this instance their axial relationship is reversed to indicate that this can be done freely as long as their previously described cooperation with the respectively adjacent annular elements remains assured.
  • FIG. 5 I have illustrated an embodiment in which I have shown the members 8 and 9, as previously indicated. In the clearance between these members there are located three (there could be fewer or more) of the annular elements each of which has the transverse wall portion 4 and the annular wall portions 3a and 3b. According to this embodiment these wall portions 3a and 3b are provided in the region of their opposite axial ends with recessed annular steps 24 and 25 which form shoulders on which a portion of the respectively adjacent annular element rests or is in contact.
  • each of the steps 24, 25 is slightly less than the remaining axial length of the respective wall portions 3a, 3b to the transverse wall portion 4.
  • the (in the drawing) lower two annular elements are slotted in their wall portions 3a, 3b to the bottom or roots 26, 27 of the steps, with the width of the slots being approximately one millimeter and the slots being circumferentially offset at angles of about 6. Such slotting provides the possibility of bridging substantial diameter differences.
  • the members 28, 29 are located at opposite axial ends of the trio of annular elements, correspond to the members 5 and 6 of the preceding embodiments, and are drawn together in order to axially stress the annular elements by means of circumferentially spaced bolts 50 of which only one is shown.
  • FIG. 6 shows an improved annular element having, as in the preceding embodiments, a transverse wall portion 4 and two inner and outer annular wall portions 3a and 3b, respectively.
  • the wall portion 3a is provided with an inner annulus of gear teeth (illustrated only diagrammatically) identified with reference numeral 31, and a similar outer annulus of gear teeth 32 is provided on the wall portion 3b.
  • Reference numerals 21 and 22 designate the same components as in FIG. 4.
  • These annuli 31 and 32 of gear teeth cooperate, of course, with similar gear teeth or other mating projections or recesses provided on the inner surface of the member 9 and on the outer surface of the member 8, respectively, with these surfaces being identified with reference numerals 9a and 8a, respectively.
  • FIG. 7 is reminiscent of FIG. 6 and like reference numerals identify like elements as in that Figure.
  • steps 24 and 25 previously discussed with respect to the embodiment in FIG. 5, and in addition they are provided the arinuli 31 and 32 of teeth.
  • FIGS. 8 and 9 finally, I have illustrated an arrangement in which an annular element provided with the annuli 31 and 32 of teeth is utilized. It should be noted parenthetically, that in FIG. 7 it is preferred to provide the annulae 31 and 32 on the wall portions 3a and 3b in the regions where the steps 24 and 25 are provided.
  • FIG. 8 I have illustrated an arrangement in which the embodiment of FIG. 1 is incorporated, but modified to provide it with the annuli 31 and 32 of teeth.
  • Like reference numerals as in preceding embodiments identify like elements and it should be noted that the outer diameter of the annular portion 7 is slightly less than the inner diameter of the wall portion 3a, so that a slight clearance remains between them.
  • the inner surface of the outer element 9 is provided with projections capable of mating with the teeth of the annulus 32, for instance another annulus 33 of teeth, and the non-illustrated shaft (such as the shaft 8 of FIG. 5) will similarly be provided on its outer circumferential surface with mating engaging portions, for instance another annulus of gear teeth.
  • a plurality of bolts a, 10b (only one shown) provide for axial stressing of the arrangement, in the same manner as discussed as for instance with respect to FIG. 1.
  • the arrangement of FIG. 8, again minus the inner member 8 of FIG. 5, is shown in top-plan view in FIG. 9.
  • An arrangement of the character described comprising a substantially cylindrical inner member having an outer circumferential surface and a longitudinal axisyan annular outer member coaxially surrounding said inner member and having an inner circumferential surface defining with said outer circumferential surface an annular clearance; connecting means received in said clearance for connecting said members against relative movement, said connecting means including at least one annular element of elastically yieldable material having a transverse wall portion extending transverse to said axis across said clearance, and an inner and an outer annular wall portion having spaced axial ends and extending in opposite directions axially of said clearance beyond said transverse wall portion by a predetermined distance; and stressing means operative for subjecting said annular element to axial stresses to thereby effect radial displacement of one of said axial ends relative to the other so that said annular wall portions respectively frictionally engage said surfaces, said stressing means comprising a pair of annular stressing members located at opposite axial sides of said annular element and each having at a side facing the same at least one annular bead projecting axially
  • annular element having a first axial side from which said inner annular wall portion projects and a second axial side from which said outer annular wall portion projects; and further comprising an outer annular ridge projecting from said first axial side and an inner annular ridge projecting from said second axial side, each of said ridges projecting from the respective axial side a distance slightly smaller than said predetermined distance.
  • annular element is of substantially Z-shaped axial sectional configuration.
  • annular portions of said annular element are of substantially identical axial length.
  • annular wall portions having at the respective axial ends recessed annular steps which engage the respective stressing members; and wherein the axial length of said annular steps is smaller than the axial distance between said steps and said transverse wall portion.
