Description

(54) HINGE OF EQUAL ANGULAR SPEEDS

one

The invention relates to mechanical engineering and can be used for synchronous transfer of rotation between units with intersecting shafts in heavy loaded gears.

A known joint of equal angular velocities, comprising two heads mounted on intersecting shafts and an intermediate device for transmitting rotation between the heads 1.

A disadvantage of the known construction is its complexity and low load capacity, since the transfer of torque is carried out by the core system, subject to the action of cantilever bending. In addition, the known device has a large installation dimensions, limiting its use in drives.

The purpose of the invention is to simplify the design and increase the load capacity of the hinge of equal angular velocities.

This goal is achieved due to the fact that in the joint of equal angular velocities containing two heads mounted on intersecting shafts and an intermediate device for transferring movements between the heads, the latter is made in the form of contacting in the form of two crackers, each of which has the shape of a half-cylinder, and each and made in the form of a cylinder with a segmental notch, the height of which is at least equal to half the diameter of the head and a seat for crackers on the notch plane, while the crackers are movably mounted in the nests of the columns the possibility of contact with one another on a planar face m and equal angles with respect to the axes of rotation

10 heads.

FIG. 1 shows the hinge, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The hinge contains heads 1 and 2 mounted on bearings 3 and 4 of shafts

15 5 and 6, with moving axles.

In the slots 7 and 8 are installed crackers 9 and 10, contacting on flat gran.

The hinge works as follows.

When the shaft 5 is rotated with the head 1, the flat bread rusk 10 can occupy any position in space, but it corresponds to a certain angle of rotation of the head 1, since the cracker 10 has only one degree of freedom.

When the crackers 9 and 10 are joined by planes, one common plane is formed, along which they are in contact with each other. This common plane can only be aligned with respect to heads 1 and 2, forming the same angles with their axes, since all parameters are the same (dimensions and arrangement of elements), therefore, synchronous rotation will be transmitted to shaft 6 connected to the head.

The proposed hinge retains an increased load capacity, does not require high precision manufacturing, and can be manufactured using standard equipment, which makes it possible to use it widely.
