Definitions

  • the invention relates to the field of mechanical engineering and is intended for the accumulation of kinetic energy.
  • the design of a tape super flywheel is known, made by winding a high-strength steel tape with gluing the turns onto the ring-shaped element of the hub center, where the centering of its tape rim, which elastically increases its diameter during rotation, is provided by deformation of the outer part of the hub center from an elastic material equipped with holes additionally filled with ballast weights (RU 143703, 03/31/2014, authors N.V. Gulia, A.I. Lavrent'ev, etc.)
  • This design is taken as an analogue.
  • the disadvantage of the analogue is the possibility of misalignment of the hub centers at high speeds.
  • the disadvantage of the prototype is the assembly of the device from the inside of the rotor, otherwise it becomes impossible. Meanwhile, such an assembly is technically impracticable for tape super flywheels, which allow assembly only outside the rotor, even before winding the tape onto the hub disks, and the support of the centering bushings must necessarily fall on the outer annular hub disc, which is in contact with the tape winding.
  • the technical objective of the present invention is to create a reliable centering of the rapidly rotating parts of the hub centers and tape rim, with the possibility of easy and cheap manufacturing of the device for such centering.

  • the finger rods would be made composite (detachable) of two parts - an inner, smooth cylindrical, with a diameter corresponding to the diameter of the hole in the inner cylindrical part of the hub center, and the outer one - in the form of a threaded cylinder screwed into the outer part of the hole for a threaded finger rod along the outer part of the hub center.
  • the outer cylindrical part of the hub center would be made with axial holes located along its periphery with the possibility of their complete and / or partial filling with material with a density greater than the density of the material of the outer cylindrical part of the hub center with the possibility of providing static balancing of the super flywheel.
  • the hub center both in the outer and in the inner part, would be made of a composite of several disks located along the axis of the super flywheel and fastened together.
  • the outer cylindrical part of the hub center would be made of duralumin, and the keys or finger rods would be made of steel.
  • the value of the larger base of the trapezoid of the key section would be determined from the conditions of tight fit of the material of the outer cylindrical part of the hub center of the super flywheel during its rotation, and the smaller base of the trapezoid of the key section during the rotation of the super flywheel would be determined from the conditions of its backlash-free fit to the inner cylindrical part of the hub center.
  • the inner cylindrical part of the hub center, into the outer cylindrical part of which the inner threadless ends of the finger rods partially enter, would be made with recesses between the holes for the entrance of the finger rods to reduce elastic deformations of the holes for the finger rods during the rotation of the tape super flywheel.
  • the specified features of the invention are essential and interconnected by a causal relationship with the formation of a set of essential signs sufficient to achieve the technical result, which consists in ensuring reliable centering of the rapidly rotating parts of the hub centers and the tape rim, with the possibility of easy and cheap manufacturing of the device.

  • the tape rim 1 is tightly fitted with its inner cylindrical surface on the outer cylindrical part 4 of the stepped center.
  • the device also contains the inner cylindrical part of the 5-step center.
  • a feature of the invention is the presence of centering means located between the outer cylindrical part of the 4-step center and the inner cylindrical part 5 of the hub center and can be made in the form of at least three dowels 6 with a cross-section in the form of an equilateral trapezoid mated on a smaller base with a rectangle.

  • the outer cylindrical part 4 of the hub center is statically tightly seated on the inner cylindrical part 5 of the hub center in the landing zone 9 and their joint static centering is carried out along the said zone landing 9.
  • Holes 7 and 8 can be filled with material 10 having a higher density than the material of the key 6 itself or the material of the outer cylindrical part 4 of the hub center for weighting.
  • the centering means can also be made in the form of cylindrical finger rods 11, which with their outer outer ends 12 are tightly coupled with the outer cylindrical part 4 of the hub center.
  • recesses 13 can be made between the holes.
  • the inner cylindrical part 5 of the hub center is usually mounted on a support shaft 14 for transmitting torque in a known manner.
  • the device operates as follows.
  • the tape rim 1 When spinning a super flywheel, the tape rim 1 increases its diameter, while the outer cylindrical part 4 of the hub center is pressed against its lower turn of the tape, the clamping of which increases either the mass of the key 6 or the cylindrical finger pin 11, tightly connected with the outer cylindrical part 4 of the hub center, for example, a tight fit for the keys 6, or a threaded connection - on the outer cylindrical ends 12 of the finger rods 11.

  • the recesses 13 in the inner cylindrical part 5 of the hub center allow to reduce the stresses from rotation in the projections with holes for the pin rods 11, which can cause distortions of the cylindrical shape of the holes for the pin rods 11, which facilitates their movement in the holes.
  • the centering of the tape rim 1 of the super flywheel relative to its axis of rotation of the shaft 14 is guaranteed.
