A stack of metallic laminations, a metallic lamination and a process for forming a lamination stack. The stack of laminations includes at least one locking lamination provided with at least two locking openings and at least one passage lamination comprising at least two passage openings, each locking lamination incorporating a tab that passes through a passage opening of a lamination seated against the locking lamination, said tab being bent so as to be contained in said passage opening and seated on an edge portion of the latter, deformed to the inside of the locking opening of the locking lamination, and at least one of the parts of locking lamination and passage lamination further comprising a lock means actuating in a lock receiving means provided in the other of said parts.
A stack of metallic laminations comprising at least two superposed laminations comprising at least one locking lamination medianly provided with at least two locking openings and with at least one passage lamination comprising, medianly, at least two passage openings, each locking lamination incorporating, adjacent to each locking opening, a tab projecting to one of the sides of said locking lamination, in order to pass through a passage opening of a passage lamination seated against the locking lamination, said tab being bent so as to be contained in said passage opening of the passage lamination and partially seated on an edge portion of the same passage opening of the passage lamination, deformed to one of the sides of said passage lamination to the interior of the locking opening of the locking lamination, axially locking the latter to passage lamination, at least one of the parts of locking lamination and passage lamination further comprising a lock means actuating in a lock receiving means provided in the other of said parts, in order to provide a relative rotational locking between each two adjacent laminations.
A lamination to form a stack of superposed metallic laminations, characterized in that it comprises, medially, at least two locking openings, said lamination incorporating, adjacent to each locking opening, a tab projecting to one of the sides of said lamination, said lamination further comprising at least one of the parts of lock means and lock receiving means, so as to provide a relative rotational locking between each two adjacent laminations.
A process for forming a stack of superposed metallic laminations comprising the steps of:
