    d t in interaction with the conical discs or out of it. In this case, the rollers slip relative to the plates, which reduces the reliability of transmission. In addition, the implementation in the known construction of plates with rectangular-shaped holes leads to a significant concentration of stresses on the transitional radius sections of the holes, which also adversely affects the strength of the circuit and its reliability in operation.
    The purpose of the invention is to increase the reliability of the circuit.
    The goal is achieved by the fact that in a transmission chain for transmission with conical disks, there are interconnected links in the form of plates with rectangular openings with rounded corners, each of which is spherically connected to the neighboring plates by means of two rollers the perforated plates of the plates ;; and the planes of the latter, with the ability of their ends to interact with the comic surfaces of the discs with the formation of friction surfaces and their lateral surfaces F1 - with the the possibility of rolling on the vertical lateral sides of the holes 3 in the plates, while the said side surfaces of the rollers are made with a radius, curvature smaller than the radius of curvature of the vertical sides of the holes in the plates, on the vertical sides of the holes in the plates are made projections longitudinal grooves 5 are made under the said protrusions of the plates, while the rollers are installed in the openings of the plates with the possibility of rolling the end surfaces of the protrusions along the corresponding surfaces The base of the bases of the recesses of the rollers. In addition, the end surface of the protrusions of the plates is cylindrical. The tangential plane drawn in the end surface of the protrusion of the plate at the intersection of the latter with the longitudinal axis of the plate is an angle less than 90 with said longitudinal axis, and the tangent plane drawn in the end surface of the protrusion of the plate at its lower point is longitudinal the plate axis is right angle. The tabs of the plates are made in the form of intermediate inserts fixed by means of at least one longitudinal rib on the vertical lateral sides of the hole in the link plates. The grooves in the rollers are made with parallel bases, and the side surfaces of the rollers are cylindrical and arranged symmetrically with respect to the planes passing through the longitudinal and transverse central axes of the cross-section of the rollers. The protrusions are made in the form of intermedi- ate inserts with an i-shaped cross-section, which are placed in recesses made on the upper lateral sides of the holes in the plates. At the ends of the side surfaces of the intermediate inserts, which interact with the side vertical walls of the holes in the plates, there are hundreds of transverse stops for fixing the plates from longitudinal movement relative to the inserts. The end surfaces of the rollers are convex. The rollers are made with rounded transitional areas between their face and side surfaces. 134 FIG. 1 schematically shows a plate of the proposed circuit, a plan; in fig. 2 shows section A-A in FIG. 1j in FIG. 3 - roller; in fig. 4 - the same, side view; in fig. 5 is a chain segment in c6opej in FIG. 6 is the same, an embodiment with spring ring locks mounted on the ends of the rollers in FIG. 7 shows the proposed transmission chain for transmission with conical disks, top view in FIG. 8 - chain plate assembled with a roller at the moment of roller rolling along the end surface of the plate protrusion; in fig. 9 and 10 are variants of the plates and chain rollers with different shape of the protrusions of the plates and recesses of the rollers; in fig. 11 is a chain section, an embodiment of the protrusions of the plates in the form of intermediate inserts; FIG. 12 — chain roller, an embodiment with cylindrical end surfaces; in fig. 13 chain plate with intermediate inserts assembled with rollers; in fig. 14 intermediate element; in fig. 15 chain plate complete with rollers, an embodiment of protrusions in the form of inserts with an i-shaped cross section; in fig. 16 - insert with a U-shaped cross section; in fig. 17 - chain segment assembly with an intermediate insert, a longitudinal section. The transmission chain for transmission with conical disks contains interconnected links in the form of plates 1 with openings 2 of rectangular shape with rounded corners. Each plate 1 is pivotally connected to two adjacent plates by means of two rollers 3 installed in the holes 2 of the plates perpendicular to the plane of the latter with the possibility of their ends 4 and 5 interacting with the conical surfaces of the disks with the formation of friction surfaces. FIG. 1-10 depict an embodiment of the chain elements according to which on the vertical lateral sides 6 and 7 of the openings 2 in the plates 1, the protrusions 8 are made, and on the lateral surfaces of the rollers 3 there are longitudinal recesses 9 for the projections 8 of the plates. In this case, the rollers are installed in the holes of the plates with the possibility of rolling the end surfaces of the protrusions 8 along the surfaces 511 of the bases of the longitudinal recesses 9 of the rollers corresponding to them. The plate (Fig. 1) is made with a hole 2 having vertical side sides 6 and 7 and horizontal sides 10 and 11, which are interconnected along the radius. The end faces 12 of the protrusions 8 are filled with cylindrical, with the tangent plane 13 drawn to the end surface 12 of the plate protrusion at the point of intersection of the latter with the longitudinal axis of the plate, the angle ci is less than 90 ° with said longitudinal axis, and the tangent plane 14, drawn to the end surface of the protrusion of the plate at its lower point, is with the longitudinal axis of the plate angle ft, equal to 90 °. The roller (Figs. 3 and 4) is made with two longitudinal symmetrically arranged recesses 9, the bases 15 of which have a flat shape and are parallel to one another, and the side surface is cylindrical with a hollow. At the ends of the rollers there are grooves 16 for installing spring ring locks 17 in them, pressing the chain plates to each other. In the preferred embodiment, the gaskets 18 are installed between the spring locking ring locks 17 and the plastic and 1. The chain plates in FIG. 7 are shown spaced apart from each other in order to make the image more distinct, in reality, the plates of the chain abut one another and can be divided into two groups, pre-compressed spring elements. FIG. Figure 8 shows the moment before the chain entrance between the conical disks, i.e. when the roller is not yet clamped between them. In this case, the lower angle 19 of the protrusion of the plate 1 is located on the lower edge of the plane of the base of the longitudinal recess 9 of the roller. When the ends of the rollers interact with the conical disks, the rolling and sliding movement of the relative protrusion of the plate protrusion takes place simultaneously until the top corner 20 of the protrusion is placed on the upper edge of the flat base of the longitudinal groove 9 of the roller. When exiting the tapered discs, the relative movement of the plate and the sleeve is carried out in the opposite direction. The presence of protrusions on the side vertical sides of the holes in the plates provides the possibility of a combined relative movement of the roller and the plate, including the movement of rolling and rolling, and prevents uncontrolled sliding. FIG. 9 shows an embodiment of the chain, according to which the ends of the protrusions 8 of the plates are made flat, and the recesses of 9 rollers with convex cylindrical bases. FIG. 12 shows a preferred embodiment of the chain rollers, according to which they have convex end surfaces, thereby eliminating the effect of a load directed toward the center. y of tapered discs, only at the ends of the rollers and consequently, the wear of the rollers is reduced. In the embodiment shown in FIG. 13, the protrusions of the plate are made in the form of intermediate inserts 21 passing through several plate-like links and fixed therein by at least one longitudinal rib 22 placed in the corresponding recesses 23 on the side vertical walls of the holes in the plates. With this design of the chain elements, the conditions for their lubrication are improved and, therefore, the wear of the contacting elements is reduced. The protrusions of the plates according to one of the embodiments (Fig. 15) can be made in the form of intermediate inserts with an i-shaped cross section 24 fixed to the side vertical walls of the holes in the plates, which also provides good lubrication conditions for the rollers. FIG. 14 shows an intermediate insert, on the side surface of which, interacting with the side vertical walls of the holes in the plates, are transverse stops 25 designed to secure the plates from longitudinal movement relative to the intermediate inserts. In this case, the need to use spring locks to secure the plates against the rollers is eliminated, resulting in easier assembly and manufacturing of the rollers, and also reduces the bending of the rollers under the action of forces directed to the center of the conical discs. ,
    The transmission chain works as follows.
    A chain is placed between the conical disks to form friction surfaces between the ends of the rollers and the said surfaces of the disks. When the chain moves, its links successively come into contact with
    tapered discs, and when this occurs, the combined movement of the rollers relative to the protrusions of the plates, including the movement of rolling and sliding.
    The proposed transmission chain design for transmission with conical disks provides for an increase in its strength and reliability in operation, which makes it possible to use it in heavily loaded gears with obtaining a wide range of gear ratio values.
