MULTI-CARRIER LOCKING WASHERS FOR CIRCULAR SHANK Russian patent published in 2018 - IPC F16B43/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of engineering and can be used in the fastening parts on the shafts of rotating parts (gears, sprockets, pulleys, etc.). Multicarrier locking washer for fixing the key assembly including a male part, a female part having a keyway, a circular shank nut and a key, outer foot has a width b₁=3.5b without bending from the plane of the washer with the groove in which the inner foot is located, bent away from the plane of the washer in the direction opposite to the bending of said outer tabs, each of which is made with the possibility of bending into the slot of the nut. Width b₂ the groove is b₂=2b, whose length is limited by the radius R=(d₁+1.5)/2+t₂, and the distance from the landing diameter d₁ washers to the bent part of the inner foot are larger than the seating diameter of the washer and is l=d₁+0.75+t₂-2.5s, where d₁ – landing diameter of the washer, s is the thickness of the washer, b – depth of the keyway of the female part.

EFFECT: technical result consists in simplifying the design of the male part, reducing the time of its manufacture by performing the folded inner paw of the washer outside the fitting diameter of the washer.
