Abstract

The invention relates to mechanical engineering and is intended to reduce the dynamic loads in the drives of machines. The purpose of the invention is to increase reliability and durability. The elastic coupling contains coupling halves 1 and 2 connected by radially arranged packages of elastic elements — springs 3. The ends of the packages of elastic elements are fixed in the semi-couplings by means of sleeves 4 and 6. On each sleeve 4 there is a fixed bevel wheel 5, which is kinematically connected with shaft-gear 7. When the moment is transmitted, the spring packs 3 bend, the half couplings 1 and 2 rotate relative to one another. Bevel gears 5, which engage with gear shaft 7, additionally provide rotation of the spring packs 3 relative to its axis in proportion to the torque, changing the moment of inertia of the elastic elements. 2 Il.

FIG. /

The invention relates to mechanical engineering and is intended to reduce the dynamic loads in the drives of machines.

The aim of the invention is to increase reliability and durability by reducing resonant spring oscillations.

FIG. 1 shows the elastic coupling; in fig. 2 is a section A-A in FIG. one.

Elastic coupling contains located on coaxial shafts leading 1 and driven 2 coupling halves, connected by radially arranged packages of elastic elements, for example, springs 3, have an oval cross-section and placed ends in different coupling halfs that can be rotated. AT

The national relationship between the stiffness of the coupling and the torque.

The use of this design allows to obtain different linear characteristics of both the reduction of stiffness in terms of torque, and its increase, and will also depend on the pre-installation of spring packages.

The clutch provides favorable operating conditions for drives with different ranges of workload variations. It eliminates resonant torsional oscillations in the transients of machine units, actively influencing their coupling half 1 one ends of each package 15 vibroacoustic characteristics, which are fixed in sleeve 4, which has been established, which increases reliability and long-freedom, and have a conical wheel 5 at its end, and in the coupling half 2, the second ends of each package are fixed in the sleeve 6. The coupling is provided with a gear shaft 7, kinematically connected with each conical wheel 5 and movably connected by means of, for example, a bearing s 8
