Изобретение относитс к точному приборостроению и может быть использовано дл соединени валов, расположенных под углом друг к другу.The invention relates to precision instrument making and can be used to connect shafts angled to each other.

.Известен шарнир равных угловых скоростей содержащий корпус с подшипниками дл соедин емых валов и механизм дл передачи вращени , который выполнен в виде двух зубчатых сфер, вход щих в сферические гнезда, выполненные в корпусе.. A hinge of equal angular velocities is known, comprising a housing with bearings for connected shafts and a mechanism for transmitting rotation, which is made in the form of two toothed spheres included in spherical sockets formed in the housing.

Зтот шарнир передает крут щий момент во всем диапазоне рабочих yi- лов, при этом скорость вращени одного вала относительно, другого не мен етс , а диапазон рабочих углов составл ет 60-70 р .This hinge transmits torque over the entire range of operating yines, while the speed of rotation of one shaft is relative, the other does not change, and the range of operating angles is 60-70 p.

Недостатком данного изобретени вл етс сложность изготовлени зубчатых сфер, с использованием сложного и дорогосто щего специального оборудовани .The disadvantage of the present invention is the difficulty of making toothed spheres using sophisticated and expensive special equipment.

Современное точное приборостроение требует диапазона рабочих угловModern precision instrumentation requires a range of working angles

ОТ 90 и выше, а также простой технологии изготовлени .FROM 90 and above, as well as simple manufacturing technology.

Цель изобретени - увеличение компенсирующей способности и упрощение технологии изготовлени .The purpose of the invention is to increase the compensating ability and simplify the manufacturing technology.

Поставленна цель достигаетс тем, что в шарнире равных угловых скоростей , содержащем корпус с подшипниками дл соедин емых валов и механизм дл передачи вращени , корпус выпол10 нен в виде двух шарнирно соединенных звеньев с осью поворота, совпадающей с пр мой, пересекающей оси соедин емых валов в одной точке, а механизм дл передачи вращени выполнен в The goal is achieved by the fact that in a hinge of equal angular velocities, comprising a housing with bearings for connected shafts and a mechanism for transmitting rotation, the housing is designed as two pivotally connected links with a pivot axis that coincides with a straight line intersecting the axes of connected shafts one point, and the mechanism for transmitting the rotation is made in

15 виде симметрично расположенных двух пар вилок, сид щих на цапфах, установленных на соедин емых валах, и двух плоских шарниров, звень которых соединены шарнирно с концами вилок, 15 as symmetrically arranged two pairs of forks sitting on pins mounted on connecting shafts and two flat hinges, whose links are pivotally connected to the ends of the forks,

Claims

30, the axles of the axles are perpendicular to the axis of the connected shafts, and the axes of the hinged connections of the ends of the forks with flat hinges are aligned with the straight lines,. intersecting axes of connected shafts and trunnions at one point. The proposed hinge ensures the connection of the shafts at angles up to 110 and can be made on a universal machine tool. FIG. 1 shows a hinge, a general view; in fig. 2 - the same, top view. The hinge of equal angular velocities has a body consisting of two links, for example, from the left bracket 1 and the right bracket

2. These brackets are connected to each other by pivotally axes 3 and each have a bearing for the connected I shafts t and 5. The shafts and 5 have spigots 6 and 7 at the joined ends, on which the forks 8 and 9 are turned, fitted with each with fingers 10, on which links 11 and 12 are rotated, interconnected by an axis 13 Details 11, 12 and 13 form a flat hinge. The hinge works as follows. When rotating the driven shaft of pins 6, the entire pivotal mechanism consisting of two forks 8 and two forks 9 of four fingers 10 and two flat hinges 11, 12 and 13 rotates and, through the couplings 7, the shaft 5 rotates - At any working angles, all links of the rod mechanism describe circles in planes parallel to the axis. When the working angle changes, the distance between the trunnions 6 and 7 changes, therefore, to compensate for this change, planar hinges are necessary. The proposed joint of equal angular velocities can have the widest application in a precise instrument, in particular, in the reference chains of exact mechanisms, where there are no large loads, but very high 64 requirements for the accuracy and linearity of the transmitted motions. The absence of large rubbing surfaces makes this hinge particularly convenient for operation in high vacuum conditions. The proposed hinge can also work as a power one, conveying considerable torques. The proposed hinge, due to the large range of working angles, allows it to be used in precise reference chains where it is necessary to install two different hinges of other types. In addition, it is easy to make. Claim of the invention An equal angular velocity hinge, comprising a housing with bearings for connecting shafts and a mechanism for transmitting rotation, characterized in that, in order to increase the compensating capacity and simplify the manufacturing technology, the housing is made in the form of two articulated links with an axis of rotation coinciding with a straight line intersecting the axes of the connected shafts at one point, and the mechanism for transmitting rotation is made in the form of symmetrically arranged two pairs of forks sitting on pins mounted on the connected shaft x, and two flat hinges, the links of which are pivotally connected to the ends of the forks, in this case. the axes of the axles are perpendicular to the axes of the connected shafts, and the axes of the hinged connections of the ends of the forks with flat hinges are aligned with the straight lines intersecting the axes of the connected shafts and axles at one point.
