Cogging element and cogging structure

Abstract

The invention relates to a cogging element ( 11, 21 ) for a cogging structure with contact surfaces ( 12, 22 ) for abutment against adjacent cogging elements ( 11, 21 ) in a common plane or against a base, and lateral surfaces ( 13, 23 ) for the formation of the sides of the cogging structure. At least one end ( 14, 24 ) of the cogging element ( 11, 21 ) has bevelled end surfaces ( 15, 25 ) which form angles ( 16, 26 ) with the lateral surfaces ( 13, 23 ) and are adapted to corresponding bevelled end surfaces ( 25′ ) in ends of other cogging elements ( 11′, 21′ ) in an intersecting plane, and the cogging element's end ( 14, 24 ) is adapted to be fastened or provided with at least one fastening element ( 31 ) in the form of a screw for fastening to a corresponding end ( 24, 14 ) of another cogging element ( 21, 11 ) in extension of the cogging element ( 11, 21 ) in the same plane. The invention also relates to a cogging structure which is composed of the cogging elements.
