ATTACHMENT OF ASSEMBLY ON MOVABLE SHAFT Russian patent published in 2025 - IPC F16D1/06 

FIELD: mechanical engineering.

SUBSTANCE: attachment of assembly on movable shaft includes assembly attached to shaft, shaft and hold-down nut. On shaft section adjoining the seat of hold-down nut that secures working assembly, there are lengthwise trapezoidal grooves running along part of the threaded section. Hold-down nut screwed onto the threaded section consists of two sections: the first one is hexagonal and the next section is a hollow cylinder, the inner part of which has the same thread as the hexagonal one and adjacent to the assembly seat. In the cylindrical section side walls there are holes where steel balls protruding from these holes can be placed, which are recessed in the shaft grooves passing along the threaded section part, and which are then limited by the ring from the outside covering the hold-down nut cylindrical section, which working position on the hold-down nut is fixed by the lock ring.

EFFECT: higher reliability of the attachment.
