Description

[0001] The invention relates to gear drives for transmitting rotary motion. The invention can be used in mechanical engineering for the creation of equipment and systems for all areas of industry, transportation, equipment manufacturing, and construction. Technical background

[0002] Applications of a universal self-centering system are known from inventions DE 10 2012 001 232 A1, DE 10 2014 003 958 A1, RU 2 587 256 C1 and RU 2 582 158 C2. A drawback of these universal self-centering systems is that the axes of rotation of a medial and an outer foundation may not coincide, which complicates the use of the dynamic properties of the universal self-centering systems.

[0003] The inventions listed above utilized static properties of universal self-centering systems. The present invention utilizes a dynamic property of a universal self-centering system: the joint rotation of a medial and an outer foundation, which are connected to each other, is possible even if the axes of rotation of the foundations do not coincide. This means that when a driving torque acts on one of the foundations, the medial and the outer foundation each rotate with respect to their non-coincident axes of rotation. During the joint rotation of the foundations with non-coincident axes, a closed chain, a closed belt, or a closed rope connecting sprockets, rollers, or pulleys of the foundations is displaced.The forward motion of the closed chain, belt, or rope is converted into a rotational motion of an output shaft of the universal self-centering system. In the present invention, geometric centers of the foundations are used instead of rotational axes of the foundations.

[0004] One aim of the invention is the stability of the arrangement of the rotation axes of the foundations and the use of the geometric centers of the foundations. Disclosure of the invention

[0005] The stated objective is achieved by a universal self-centering system according to claim 1. A universal self-centering system with an outer and a medial base, on which sprockets, rollers, or discs are rotatably mounted and sequentially connected by a closed chain, belt, or rope, has a common and fixed axis of rotation for both the medial and outer bases. The sprockets, rollers, or discs of the outer base are linearly displaceable along the base. The common and fixed axis of rotation of the bases is realized, for example, by fixing these bases to a rotary bearing. The linear displacement of the sprockets, rollers, or discs is ensured, for example, by mounting the axes of rotation of the sprockets, rollers, or discs on springs.

[0006] In a specific example, the universal self-centered system with the common and unchanging axis of rotation of the foundations comprises a medial foundation 1 and an outer foundation 2, which are connected to each other via a bearing 3. Foundation 1 and foundation 2 are angularly displaceable relative to each other with respect to the common axis, which coincides with an output shaft 12. The output shaft 12 is rotatably mounted on the medial foundation 1 by means of a bearing 21. On the outer foundation 2, sprockets 9, 10, and 11 are rotatably mounted with respect to axes 6, 7, and 8. Axes 7 and 8 are mounted on a spring 19, which allows these axes 7 and 8, together with sprockets 10 and 11, to be displaced along openings 25 and 26. On the medial foundation 1, sprockets 13, 14, and 15 are rotatably mounted with respect to axes 22, 23, and 24. The sprockets 9, 14, 10, 15, 11, 13 are sequentially connected by a closed chain 5.An input shaft 27 is mounted on the medial foundation 1. Gears 16, 17, 18 are rotatably mounted on sprockets 13, 14, 15 with respect to axes 22, 23, 24. Gears 16, 17, 18 mesh with a gear 20 mounted on the output shaft 12. The arc 4 passing through axes 6, 7, 8 defines a geometric center of the outer foundation 2. The geometric center of the outer foundation 2 coincides with the geometric center of the medial foundation 1 and with the axis of the output shaft 12 when the sprockets 10 and 11 of the output shaft 12 are aligned, as shown in Figure 1. Fig. 4, are maximally approximated. A tension in the chain 5 is realized by means of an angular inversion of the medial foundation 1 with respect to the outer foundation 2. On Fig. 1 is the geometric center of the outer foundation 2 shifted by the size 129.91 with respect to the geometric center of the medial foundation 1.

[0007] If the geometric centers of the outer foundation 2 and the medial foundation 1 are as shown in Fig. When 4 are in agreement, the medial foundation 1 and the outer foundation 2 rotate with identical angular velocity. All sprockets 9, 10, 11, 13, 14, 15 and gears 16, 17, 18, 20 do not rotate, and the chain 5 is not displaced along its perimeter. The angular velocity of the output shaft 12 is zero.

[0008] If the geometric centers of foundations 1 and 2 do not coincide, as shown in Fig. 1, the chain 5 is displaced along the perimeter. All sprockets 9, 10, 11, 13, 14, 15 and gears 16, 17, 18, 20 rotate; the drive torque is also transferred from gears 16, 17, 18 to gear 20 and the output shaft 12. The number of revolutions of the output shaft 12 for one revolution of the medial foundation 1 and the input shaft 27 can be estimated from the information provided on Fig.Figure 1 shows the following. If the medial base 1 rotates by an angle of 120 degrees, sprocket 9 will assume the position of sprocket 10, sprocket 14 will assume the position of sprocket 15, and chain section 596.36 will occupy the position of chain section 795.68. For one full revolution of base 1, chain 5 will be displaced by the amount (795.68 - 596.36)³ = 597.96. With a radius of 100 for gears 16, 17, and 18, and 130 for gear 20, the output shaft 12 will rotate (597.96 / 6.28 * 100) * 100 / 130 = 0.73 revolutions. If the angular velocity of the input shaft 27 is equal to SZ, then the angular velocity on the output shaft 12 will be equal to SZ * 0.73. This velocity will decrease smoothly to zero if the load on the output shaft 12 is increased sufficiently to fully overcome the effect of the spring 19.In the universal self-centering system, sprockets, rollers or discs can be used that are sequentially connected to each other by a closed chain, belt or rope.
