CONSTANT-VELOCITY JOINT Russian patent published in 2023 - IPC F16C11/00 

FIELD: mechanical engineering.

SUBSTANCE: hinge of equal angular velocities contains the outer and inner parts of the hinge, the inner part of the hinge consists of two rods connected to each other by means of a hinge connection with a spherical segment made at the end of the first rod, and a flange with an internal hemispherical segment corresponding in shape to the spherical one is made at the end of the second rod segment of the first rod, the outer part of the hinge consists of two flanges, on the contact end surface of which prismatic grooves are made, in addition, the outer part includes a flexible shaft made hollow, in the form of blades, prismatic protrusions are made on the ends of the flexible shaft, corresponding to prismatic grooves on the end surfaces of the flanges , while the flexible shaft is made of an alloy with a shape memory effect.

EFFECT: ensuring the transfer of torque between the mating parts of the hinge having mating surfaces corresponding to the mating surfaces of the splined type of connection of parts, increasing the service life and bearing load capacity of the hinge.
