Definitions

  • a rotary member has an axis of rotation and is provided on its circumferential face with a first annulus of teeth, and on one of its axial end faces with a second annulus of teeth.
  • the present invention relates to a rotary motion-transmitting device, and more specifically to a device of this type which has particular utility in conjunction with toy assembly kits.
  • gear wheels rotary motiontransmitting devices
  • toy assembly kits rotary motiontransmitting devices
  • gear wheels rotary motiontransmitting devices
  • the use of such gear wheels has always necessitated a certain complexity in the provisions which had to be made for mounting the gear wheel and the auxiliary devices to which the gear wheel was to transmit motion or from which it was to receive motion.
  • gear wheels have lacked versatility in that the simultaneous transmission of motion to more than one auxiliary element required complicated constructions often beyond the skill of children for whom the toy assembly kit was intended.
  • a more specific object of the invention is to provide a gear wheel which is highly versatile in the construction of motion-transmitting arrangements.
  • An additional object of the invention is to provide a gear wheel such as outlined above which is simple and inexpensive to construct and whose use in conjunction with other elements of a toy kit does not require the provision of tools.
  • An additional object of the invention is to provide such a gear wheel whose assembly to devices to which it is to transmit motion, or from which it is to receive motion, requires little manipulative skill.
  • a rotary motion-transmitting device such as a gear wheel, which comprises a rotary member having an axis of rotation and which includes a plurality of motiontransmitting portions spaced from this axis of rotation.
  • a gear wheel has, in accordance with the invention, not only an annulus of teeth provided on its peripheral surface and constituting a spur gear, but also another annulus of teeth provided on one of its axial end faces and constituting a face gear.
  • my novel gear wheel is provided with other motion-transmitting means, such as one or more pins provided on that axial end face opposite the one which carries the second annulus of teeth, and openings extending from one to the other of these axial end faces and arranged to accommodate shafts which may serve as pivot axes. Both the openings and the pin or pins extend in axial parallelism with the axis of rotation of the gear wheel but are arranged off-center relative thereto.
  • FIG. 1 is an axial end view of a gear wheel in accordance with the present invention
  • FIG. 2 is a partially sectioned elevation of a right-angle drive, utilizing a gear wheel of the type shown in FIG. 1;
  • FIG. 3 is a top view, partly sectioned, of the gear wheel shown in FIG. 1, showing the same in an arrangement utilizing a sheave and another auxiliary member.
  • FIG. 1 the gear wheel shown there is generally indicated with reference numeral 2 and that it is provided with a peripheral annulus of teeth 1 constituting a spur gear.
  • reference numeral 2 the gear wheel shown there is generally indicated with reference numeral 2 and that it is provided with a peripheral annulus of teeth 1 constituting a spur gear.
  • teeth 1 are illustrated only on part of the periphery of the gear wheel 2, this showing was selected only to make the drawing simple and readily understandable and that the teeth 1 actually extend over the entire periphery of the gear wheel 2.
  • a hub 4 (see FIG. 2) is removably connectable to the gear wheel 2 and is provided with one or more projections 3 which, when the hub 4 is inserted into the center opening 2' of the gear wheel 2, will engage with and be received in the complementary recesses 2" provided in the gear wheel 2, so that the hub 4- is thus non-rotatably locked to the gear wheel 2 to transmit power thereto and to receive power therefrom.
  • the gear wheel 2 is provided on at least one of its axial end faces with a second complete annulus of teeth, here indicated with reference numeral 6, only a portion of which is shown.
  • the teeth 6 constitute a face gear and serve to permit use of the gear wheel 2. in conjunction with the peripheral teeth 1 of a second gear wheel 5 (see FIG. 2) so that the two gear wheels 2 and 5 together constitute an angle drive, particularly a right-angle drive.
  • the teeth 6 are advantageously so recessed in the axial end face of the gear wheel 2 that their outermost tips are located in the plane of this end face and do not project outwardly beyond the end face.
  • a gear wheel 2 similar to the one shown in FIG. 1 can be provided with the hub 4 which is non-rotatably locked to the gear wheel 2.
  • a sheave 9 is secured to one axial end of the gear wheel 2 for simultaneous rotation with the latter in order to transmit power to, or to receive power from, the gear Wheel 2.
  • the latter is provided on that one of the axial end faces which is opposite the one provided with the annulus of teeth 6, with pins or projections 7 which, as is clearly evident from FIG.
  • the gear wheel 2 can also advantageously be provided with one or more bores 10 (see FIG. 1) which extend from one to the other of the axial end faces of the gear Wheel and are adapted to receive pins ll. or similar instrumentalities which can serve as axles or for other purposes.
  • FIG. 1 In the embodiment shown in FIG.
  • the pin 11 is inserted through a opening 10 in the gear wheel 2 and extends with one end into one of the recesses 8 provided in the sheave 9, thus serving to lock the same still more reliably to the gear wheel 2, whereas the other end of the pin ll extends into a complementary recess provided in a building block 12 or a similar element so that the latter will turn about shaft 11 and will perform a reciprocatory movement during rotation of the gear wheel 2 and the pulley locked thereto.
  • hub illustrated is well known in the art and need not be further described, beyond stating that it usually consists of two parts provided with a screw connection so that they are rotatable relative to one another, these parts being so constructed and arranged that a change in their relative positions will cause them to engage the surrounding surfaces of a member to which they are to be secured, with greater or lesser force.
  • a rotary motion-transmitting device comprising a rotary member having an axis of rotation and including a plurality of motion-transmitting portions spaced from said axis, one of said motion-transmitting portions being a first annulus of teeth provided on a peripheral face of said member and another of said motion-transmitting portions being a second annulus of teeth provided on an axial end face of said member and constituting a face gear.
  • one of said motion-transmitting portions includes a surface surrounding a hole provided in said member parallel with said axis of rotation thereof.
  • said cooperating coupling means comprises at least one radially extending recess provided in the surface surrounding said opening, and a complementary projection provided on said hub and adapted to be received in said recess.
  • said cooperating coupling means comprises at least two diametrically opposite radially extending recesses provided in the surface surrounding said opening, and complementary projections provided on said hub and adapted to be received in the respective recesses.
  • a rotary motion-transmitting device comprising a rotary member having an axis of rotation and an axial endface, said rotary member being provided with a plurality of motion-transmitting portions spaced from said axis including a plurality of teeth arranged in said axial endface and constituting a face gear, said teeth comprising tips which are flush with the general plane of said axial endface.
  • a rotary motion-transmitting device including :a rotary member having an axis of rotation and an axial endface, said rotary member comprising a plurality of motion-transmitting portions spaced from said axis :and including at least one integral projections extending from said axial endface.
