BOLTED CONNECTION OF PARTS FROM MATERIALS WITH DIFFERENT COEFFICIENTS OF THERMAL EXPANSION Russian patent published in 2024 - IPC F16B5/02 

FIELD: machine building.

SUBSTANCE: invention relates to bolted joints of parts made from materials with different coefficients of thermal expansion. Bolt joint comprises the first part, the second part and bolts connecting the parts to each other, it is made so that slots are made in the first part so that the latter can slide along the bolts installed in these slots. Slots are oriented along beams having a common point of intersection in the plane of connection of parts, which serves as a pole of thermal deformations, wherein the pole of thermal deformations is not a rigidly fixed point and there is no bolted connection in it.

EFFECT: providing uniform distribution of transverse loads on bolts and, as a result, reducing maximum stresses in bolts while ensuring thermal decoupling of connected parts.
