Definitions

  • the product relates to rotational motion transmission devices, in particular, to wave gears and is intended for use in gears, for example, gearboxes or in adjusting mechanisms in various fields of technology.

  • a wave generator or hereinafter abbreviated as a generator
  • a flexible gear wheel or hereinafter abbreviated as a flexible wheel
  • a rigid gear wheel or further abbreviated as hard wheel
  • a flexible wheel typically has a radially deformable part of the generator and a non-deformable part associated with the output link.
  • the described structures have a high ability to absorb the load with small dimensions in the radial direction. However, due to the need to separate the flexible wheel into deformable and non-deformable parts, the dimensions of the gears in the axial direction are very significant.
  • a close technical solution to the claimed design is a wave gear transmission described in the invention DE 10021236; F16H1 / 32; 11/15/2001, containing a planetary wave generator connected to the input link, a hard gear connected to the first output link, and a flexible gear gear meshed with the outer teeth with the hard gear and the internal gear teeth with the gears of the satellites of the planetary wave generator .
  • the rotation from the flexible wheel to the second output link is transmitted by flexible spokes having an arcuate or S-shape, allowing the flexible wheel to deform in the radial direction.
  • a particular case of this invention is a variant in which the spokes are straight in shape, but approximately in the middle, and the parts of the spokes attached to the flexible wheel are engaged with the spokes connected to the hub of the output link.
  • This design allows to reduce the dimensions of the wave transmission in the axial direction due to the connection of the flexible wheel with the output link in the zone of deformation of the flexible wheel, but does not allow to bring the output link directly to the zone of deformation of the flexible wheel due to insufficient, in this case, stiffness of the spokes. Because of this, the possibility of axial size reduction is not fully utilized.
  • Known designs in which the connection of the flexible wheel with the output link is made in the immediate vicinity of the zone of engagement of the flexible wheel with a rigid wheel.
  • the invention Na198079, 1967, which presents the construction of a wave gear train containing a generator connected to the input link, a hard wheel connected to the first output link, and a flexible wheel connected to the second output link by engaging the protrusions on the end surface of the flexible wheel (or hereinafter abbreviated as protrusions) for cylindrical or prismatic radial guides,
  • the unique advantage of this design is that it provides the smallest possible dimensions of the gear in the axial direction, making it practically flat, and the disadvantages that impede its use are the result of the fact that the surface points of each protrusion of the flexible wheel move relative to the fixed output links along curved closed paths elongated in the radial direction, and interact, in this case, with points located on the rectilinear generatrices of the cylindrical surface or prismatic surface of the guides of the output link.
  • the fact that the points of the flexible wheel move along closed curved paths can be understood by referring to the chapter devoted to wave transmissions of the book by M.N.

  • a point located on a portion of a flexible wheel with a variable curvature and dividing this portion into two sections of the same length will be shifted in a circumferential direction towards a portion with a greater curvature, that is, the angle bounding the portion with a greater curvature will be smaller than the angle bounding plot with less curvature.
  • the rectilinear generators of cylindrical or prismatic guides must pass along the tangent to the motion path of the protrusion points interacting with them. That is, each protrusion, making one cycle of its movement along a closed trajectory, once touches one guide adjacent to it and once another. This means that at that moment in time when two protrusions that are in opposite phases of the cycle of their motion touch the guides, there is no play in the mesh. But, at the next point in time, when the protrusions move away from the guides, a backlash will appear and, then, will disappear again when the next pair of protrusions will be taken away from the guides.
  • the maximum number of pairs that can simultaneously touch rectilinear guides is small, it is equal to the number of pairs with matching phases of the cycle and does not depend on the total number of protrusions, for example, in a two-wave transmission there can be no more than two, but in a three-wave transmission no more than three.

  • the closest analogue of the claimed inventions can be called the invention Ns 198079, 1967.
  • This design provides the axial dimensions of the wave gear, but its operability is limited by the following problems: there is a play in the connection of the flexible wheel with the output link, which reduces the accuracy and smoothness of the transmission, reduces its ability to transmit torque from the flexible wheel to the output link and perceive the load, especially the dynamic, from external forces by the output links; play can be reduced, and the accuracy and smoothness of transmission can be increased by increasing the number of protrusions at the end of the flexible wheel that engage, but this will lead to a decrease in the length of the protrusions in the circumferential direction, and therefore to a decrease in their strength and stiffness, while each protrusion It experiences significant loads during transmission of torque due to the small number of protrusions interacting with the guides at the same time.

  • each protrusion moving along a closed curved path relative to the second output link will always touch the surface forming the hole into which this protrusion enters, and every two protrusions that are in opposite phases of the cycle of their movement, they will prevent the output link from turning relative to the flexible wheel - one in one and the other in the other direction - thus transmitting torque and obstructing play.

Abstract

L'objet de l'invention fait partie des transmissions ondulatoires planes et peut s'utiliser dans des réducteurs ou dans des mécanismes régulateurs, dans de différents domaines de la technique. Les quatre inventions visent à améliorer la capacité de fonctionnement de la transmission ondulatoire plane dans laquelle la roue souple (140) est reliée à une articulation de sortie (130) dans la partie déformable grâce à l'engrènement de ses protubérances d'extrémité (43 et 43') avec les raccords entre les orifices (33 et 33') de l'articulation de sortie (130). A cette fin, on augmente la rigidité et la résistance du raccord, on élimine tout jeu et l'on assure une transmission avec précision et en douceur grâce à ce qui suit: la forme des orifices (33 et 33') qui assure le contact permanent de l'articulation de sortie (130) avec les protubérances (43 et 43') de la roue souple (140); le renforcement des protubérances (43 et 43') par les dents (44 et 45, 44' et 45') de la roue souple (140); la réalisation des protubérances (43 et 43') interagissant avec l'articulation de sortie (130) sur les deux extrémités de la roue souple (140); la réduction de la charge sur les protubérances d'extrémité (43 et 43') de la roue souple (140) en cas de leur torsion souple, provoquée par cette charge, par sa redistribution de sa partie sur les articulations de sortie (120 et 130) au moyen de l'interaction avec les appuis axiaux (60 et 60').
