FIELD: machine engineering.
SUBSTANCE: band is used with width of 0.3-3 height tooth ring gear and manufactured not to exceed the width of 0.5 of its thickness. Forming the protrusions and depressions serrated tape is carried out by repeated bending of the strip flexagon. When this flex strip 180° relative to a line lying in the plane of the blank-strip extension strips and carry along their edges. Fold the toothed belt in a spiral arrangement of planes flexagon perpendicular to the central axis of the ring gear. Toothed belt fixing is carried out with coils relative to each other and the tooth profile correction by axial compression of the toothed belt in the mould, comprising a toothed wheel with a profile congruent toothing profile.
EFFECT: increased precision of ring gears.
