POLYHEDRON WASHER BY ZIEMLYAKOV FOR INSTALLATION OF ADDITIONAL BOLT ON FACET OF HEAD

摘要

FIELD: machine building. ^ SUBSTANCE: here is disclosed polyhedron washer for installation of additional bolt on facet of head, where this bolt is designed for arresting first bolt and for holding it down to head of first bolt with lower surface. The first bolt is inserted in an orifice of a case. The polyhedron washer corresponds to a plate with lower and upper planes. The plate is polyhedron along external perimetre and has six facets along the internal orifice. Distance between opposite facets of internal orifice along the lower plane is bigger, than distance between the same facets along the upper plane of the washer. ^ EFFECT: raised reliability of arresting. ^ 2 cl, 1 dwg
