Изобретение относитс к машиностроению , а именно к устройствам дл передачи крут щего момента между соосными валами .The invention relates to mechanical engineering, in particular to devices for transmitting torque between coaxial shafts.

Известна муфта, содержаща две полумуфты , соединенные посредством промежуточного звена, состо щего из стержней, шарнирно скрепленных между собой в виде двух параллелограммов (авт.с0.№ 136609, кл. F 16 О 3/02, 1960).A known clutch comprising two coupling halves connected by means of an intermediate link consisting of rods pivotally fastened together in the form of two parallelograms (ed.c0.No 136609, class F 16 O 3/02, 1960).

Муфта динамически неуравновешена и имеет большие габариты.The coupling is dynamically unbalanced and has large dimensions.

Наиболее близкой к изобретению вл етс муфта, содержаща две полумуфты, соединенные посредством промежуточного звена в виде двух шарнирно скрепленных между собой параллелограммов, одна из осей каждого из которых закреплена на одной из полумуфт, противоположные им оси соединены между собой, а друга подумуф- та шарнирно соединена со стержн ми, расположенными по обе стороны от точки соединени параллелограммов между собой .Closest to the invention is a coupling containing two half-couplings connected by an intermediate link in the form of two parallelograms pivotally connected to each other, one of the axes of each of which is fixed to one of the half-couplings, the axes opposite to them are interconnected, and the other of the coupling is pivotally connected to rods located on both sides of the connection points of the parallelograms to each other.

Недостатками известной муфты вл ютс большие габариты и невысока эксплуатационна надежность, а также низкий КПД вследствие -большого количества шарнирных соединений.The disadvantages of the known clutch are large dimensions and low operational reliability, as well as low efficiency due to the large number of articulated joints.

Цель изобретени - повышение эксплуатационной надежности и КПД, а также снижение габаритов муфты,The purpose of the invention is to increase operational reliability and efficiency, as well as reducing the dimensions of the coupling,

Это достигаетс тем. что а деуфте, содержащей две полумуфты, соединенные посредством промежуточного звена, состо щего из стержней, шарнирно скрепленных между собой в виде параллелограмма , одна из осей шарнира параллелограмма закреплена на одной из полумуфт, противоположна ей ось шарнира параллелограмма закреплена на другой полумуфте.This is achieved by that. that a coupling containing two coupling halves connected by an intermediate link consisting of rods hinged together in the form of a parallelogram, one of the axes of the parallelogram hinge is fixed to one of the coupling halves, the axis of the parallelogram hinge is fixed to the other half coupling.

Claims

The claims

COUPLING, comprising two coupling halves connected by means of an intermediate yoke consisting of rods pivotally fastened together in the form of

Figure 1 shows the described coupling, General view; figure 2 is a section aa in figure 1.

The coupling contains coupling halves 1 and 2 s

axles, on the inverted ends of which the axles are fixed: on the coupling half 1 - axis 3, on the coupling half 2 - axis 4, the coupling halves 1 and 2 are connected by means of an intermediate link consisting of rods 5 pivotally fastened together in the form of a parallelogram (figure 2) . Axes 3 and 4 are located at opposite vertices of the parallelogram. As joints, plain or rolling bearings can be used.

Torque is transmitted between the coupling halves 1 and 2 by means of the parallelogram rods 5 and the axes 3 and 4. The movable coupling of the couplings allows to compensate for significant radial displacements of the connected shafts.

Thanks to a smaller number of articulated joints than in the prototype coupling (4 in the enclosed coupling, 11 in the prototype coupling)

the clutch has higher operational reliability and has lower friction losses in the joints, which ensures its operation with higher efficiency. In addition, the presence of one parallel

logram instead of two in the prototype due to

the connection of the hinge axes 3 and 4 in opposite vertices of the parallelogram with different half couplings allows to reduce the dimensions and weight of the device, therefore, further increase its efficiency.

The use of the invention makes it possible to reduce the dimensions and increase the operational reliability and efficiency of the coupling.

parallelogram, one of the axes of the parallelogram hinge is fixed on one of the coupling halves, characterized in that the axis of the parallelogram hinge opposite to it is fixed on the other coupling half.
