Definitions

  • a toy erection kit which includes an elongated worm gear having spaced axial end portions at least one of which is provided with a torque-transmitting portion, such as an annulus of gear teeth surrounding the axis of rotation of the worm gear, so that torque may be transmitted to or received from another element of the toy erection kit via the torque-transmitting portion.
  • a torque-transmitting portion such as an annulus of gear teeth surrounding the axis of rotation of the worm gear
  • the present invention relates to toy erection kits, and more particularly to a gear member for use in such toy erection kits. Still more specifically the present invention relates to a worm gear for use in toy erection kits.
  • the worm gear be capable of cooperatively engaging with other gears, either by direct engagement or by indirect engagement via a drive belt or the like.
  • the worm gear is driven directly by a prime mover, such an arrangement as proposed herein will be advantageous because frequently a single prime mover is in tended to drive two or more separate models or elements of a model wherein it is necessary that one model be driven at a rotational speed significantly lower than the output speed of the prime moved whereas it is desired that the other model be driven at a highed speed which may perhaps approach the output speed of the prime mover.
  • I provide, in a toy erection kit, an elongated gear member mounted for rotation about its axis and having spaced axial end portions. At least one of these end portions is constructed and arranged for torque-transmitting cooperation with another element so as to enable transmitting of torque from the gear member to or receiving of torque from the other element.
  • This gear member that is the worm gear
  • the one end portion may be configurated as a flange or disc having on its peripheral edge face a recessed groove in which a drive belt or similar instrumentality is received which can cooperate with the aforementioned other element.
  • the groove may be provided on its side walls or its bottom wall, or on both, with an annulus of gear teeth which can matingly engage with the teeth of an other gear positioned so as to permit such arrangement.
  • the end portion may be separate and be suitably secured to the remainder of the worm gear, but advantageously it will be of one-piece construction with the same.
  • FIG. 1 is a somewhat schematic illustration of a transmission arrangement utilizing a worm gear constructed in accordance with the present invention, the worm gear being partly shown in longitudinal section;
  • FIG. 2 is a detail view of FIG. 1;
  • FIG. 3 is a section taken on the line III-III of FIG. 2;
  • FIG. 4 is a further detail view, in fragmentary illustration, of a worm gear embodying a further feature of the invention.
  • reference numeral 1 identifies a worm gear which is mounted on a shaft 2 so that torque can be transmitted from the shaft 2 to the worm gear 1.
  • Reference numeral 3 identifies schematically a prime mover, for instance an electromotor or the like, and it will be understood that the shaft 2 may be the output shaft of the prime mover 3, or may be coupled in suitable manner with this output shaft.
  • a worm wheel 4- is mounted on a shaft 5 about which it rotates and which in turn is supported in a housing 6 connected in suitable manner with the prime mover 3. The worm wheel 4 is in engagement with the worm gear 1.
  • this portion 8 is of one-piece construction with the remainder of the worm gear 1, and is configurated as a disc of flange being provided in its peripheral edge face with a radially inwardly extending recess of annular configuration so that a drive belt or analogous member can be trained about the portion 8 in the annular recess.
  • Such drive belt is identified with reference numeral 9 and it will be understood that by this connection torque can be transmitted from the worm gear 1 to another, non-illustrated element.
  • torque can be transmitted from such non-illustrated other element to the worm gear if desired.
  • FIGS. 2 and 3 illustrate that in this embodiment the portion 8 is constructed as a disc or flange, as already pointed out, and that the peripheral groove is identified with reference numeral While it will be appreciated that the side walls and the bottom wall bounding this groove 10 may be smooth, it will be seen that in the illustrated embodiment the bottom wall is provided with an annulus of teeth 11, thus making it possible to utilize the portion 8 not only in conjunction with the drive belt or analogous element, but in conjunction with another gear, such as the one identified with reference numeral 12, which in FIG. 3 is shown in engagement with the teeth 11 of the portion 8 provided on the worm gear 1. Again, torque of course be transmitted to or from the worm gear 1 in this manner.
  • FIG. 4 illustrates how this construction can be made still more versatile by providing the end portion 8a, as it is designated in FIG. 4, with a plurality of gear teeth 13 which extend radially beyond the teeth of the worm gear 1. This makes it possible for these gear teeth 13 to cooperatively engage with the corresponding gear teeth of a transmission member 14 which is shown in phantom lines and which is supported and guided on the worm gear 1, simply by being slipped over the same. Engagement of the gear teeth 13 with those of the element 14 couples the latter with the worm gear 1 in torque-transmitting relationship, as will be appreciated.
  • the member 14 by having a member such as the element 14 so configurated that the element can be slipped over the worm gear from the free end thereof until the inner teeth in the member 14 engage with the teeth 13 of the portion 8a so that the member 14 is coupled with the worm gear in torque-transmitting relationship.
  • the member 14 may in turn be configurated so that it can drive a transmission belt or analogous element, or engage with the teeth of further gears.
  • the member 14 is, of course, guided by and on the worm gear 1 in this arrangement.
  • a drive arrangement comprising a prime mover having a rotatable output shaft; and a worm gear fixed to said output shaft coaxially therewith for rotation with the same about its longitudinal axis, said worm gear having spaced axial end portions at least one of which is provided with a peripheral groove surrounding said one end portion and adapted to receive belt means trained about the latter.
  • said one end portion being a disc provided with said peripheral groove bounded by bottom wall means and side wall means, at least one of said wall means being provided with an annulus of gear teeth adapted for cooperative engagement with similar teeth on another member.
  • said worm gear comprises a plurality of primary teeth, and wherein said annulus of teeth is constituted by secondary teeth, said secondary teeth projecting radially beyond said primary teeth.
  • an elongated Worm gear mounted for rotation about its axis and having spaced axial end portions at least one of which is configurated as a disc provided with a peripheral groove bounded by bottom wall means and side wall means, at least one of said wall means being provided with an annulus of gear teeth adapted for cooperative engagement with similar teeth on another member so that said worm gear may transmit torque to or receive torque from said other member via said one axial end portion.
