Abstract

The invention relates to mechanical engineering, in particular to cross couplings. The purpose of the invention is to increase the load capacity and to ensure the possibility of reducing the radial loads on the joined shafts by reducing the stiffness of the elastic support elements. The clutch contains two coupling halves with diametrically located shanks, at the ends of which end projections (TV) 5 and 6 are made. Between the coupling halves, the main and additional intermediate links 7 with radial grooves 9 are installed. On each side of TV 5 or 6, one elastic 10 and one rigid 11 support elements are installed. In each link 7 elastic and rigid supporting elements are placed with their pairwise alternating. In the main and additional intermediate links x, the relative orientation means are made in the form of holes and protrusions. The protrusions of one intermediate member enter the holes of the other. Torque when the clutch is rotated clockwise is transmitted from the half-coupling through TB 5 to the rigid elements 11 of intermediate link 7, then also through the rigid elements 11 to TB 6 of the half coupling, while rotating counter-clockwise through the elements 11 of additional intermediate link. 1 hp f-ly, 3 ill.

Description

The invention relates to the field of engineering, in particular, to cross couplings.

The aim of the invention is to increase the load capacity.

FIG. 1 shows a general view of the coupling, axial section; in fig. 2 is a section A-A in FIG. one; on r. 3 - section bb in fig. U in FIG. 4 shows an embodiment of a coupling with an intermediate element in the form of square crackers, an axial section; in fig. 5 is a sectional view BB in FIG. four; in fig. 6 is a cross-section of the FIG. four.

Cross coupling contains two coupling halves 1 and 2 with diametrically located shanks 3 and 4 and end protrusions 5 and 6 at the ends of the shanks. Installed between the coupling halves: L1 The main intermediate link 7 and the additional intermediate link 8 with rigid and elastic onopHbiNtti elements 9 and 10. In each intermediate link, the supporting elements 9 and 10 are installed in pairs alternating, with each side of the protrusion 5 or 6 elastic and one rigid support elements 9 and 10.

In both intermediate links x 7 and 8, the relative orientation means are made in the form of alternately arranged protrusions 11 and openings 12, with the protrusion of one of the coupling halves located in the opening of the other.

Intermediate links 7 and 8 can be made in the form of crosses (Fig. 1-3), and in the form of square crackers (Fig. 4-6). Each interval

the exact link in the form of square crackers is made with slit-shaped slits 1 3 in its side faces arranged in the form of a rhombus, i.e. intermediate-; my link is made in one piece with rigid and elastic supporting elements 9 and 10,

The coupling works as follows.

When the semi-coupling rotates 1 in the direction of the arrow a (see Figs. 2, 5), its projections 5 with an effort P act on the rigid supporting elements 10 of the intermediate link 7, which, in turn, with their rigid elements 10 acts on the projections 6 of the half-coupling 2, perceiving this effort with the reaction of R. While rotating the half-coupling I in the opposite direction, i.e. in the direction of the arrow 5 (see Figs. 3, 6), its protrusion 5 with a force P acts on the rigid elements 11 of the intermediate link 8, which, in turn, with its rigid elements 10 acts on the projections 6 of the half-coupling 2, which accept this force with the reaction of R,

At the same time, the elastic support elements 9 of both intermediate links do not participate in the transmission of torque from the coupling half to the coupling half and their functional purpose reduces only to ensuring the backlash-free conjugation of the rigid supporting elements 10 intermediate links 7 and 8 with the protrusions 5 and 6 of the coupling half. . „

The change in the layout of the rigid and elastic support elements in the intermediate link ensured that the clutch can transmit torque to one of the sides only through

rigid elements, the caNUM eliminated elastic elements from the work on the transfer of torque, which provided an increase in torque. The introduction of an additional intermediate link with the corresponding orientation of it relative to the main one ensured the transmission of the torque by the clutch through rigid supporting elements in both directions of rotation.
