Invention Formula

Universal joint, containing two forks with working surfaces, installed with the possibility of interaction with each other through each of the disks 3 is made with a top-30 intermediate element with two rims 6, groove 7, bottom 8 which are located in a mutually perpendicular direction 12 in interaction with the profile 5 forks 1.

Similarly, the other two are collected.

drive with another plug.

Then, the pairs of assembled disks are mated with each other along surfaces 8 and 9 of the slots 7 and fixed with screw 4 in a threaded hole formed

thread grooves 10.

When the universal joint is working, turning one of the forks around its own axis causes the other fork to turn, and the intermediate element

slips along the mating profile m 5 and 12.

The implementation of the intermediate element composite of two pairs of disks provides simplification of its manufacture,

those. simplifying the manufacture of the hinge as a whole and reducing its metal intensity.

Invention Formula

walks through the axis X-X of the disk, and its width, Toe. the distance between the side walls 9 is made equal to twice the thickness of the disk, as well as with a semi-cylindrical groove 10, the axis of which is at an angle of 45 to the axis of the disk, at an angle of 90 ° to the axis of the groove and passes through the center of the end 6, i.e. through the intersection point of the X-X with the end 6.

The conical surface 11, which, together with the similar surface of the adjacent disk, forms a V-shaped groove profile 12, is formed along the forming disk from the end face 6.

The hinge is assembled as follows.

The two disks 3 are attached to each other by ends 6, while aligning the surfaces 8 and 9 of the slots 7, and

grooves in planar planes, in order to reduce metal consumption, the projection element is made up of two pairs intersecting at a right angle, in contact with the ends of the disks, forming a V-shaped groove profile and intersecting at a right angle, also connected to each other by means of a threaded element with an axis passing through the centers of the said ends at an angle of 45 to the axis of the discs,

Moreover, in each of the disks there is a rectangular groove, the width of which is equal to twice the thickness of the disk, and the bottom passes through the axis of the disk, and also a semi-cylindrical groove, the axis of which is at an angle of 45 to the axis of the disk and under 90 to the axis of the groove the mentioned end of the disk.
