TORSION FILTRATION MECHANISM WITH CAM TRACK

摘要

The present invention relates to a torsion filtering mechanism (22) comprising: a first rotary member (24); a second rotary member (26) moving with respect to the first rotary member (24); a cam track (60) rotating with one of the rotary members (24, 26); and at least one related cam follower (36) provided in the other rotary member of the rotary members (24, 26). The cam track (60) includes a profile composed of a plurality of arcs (0, A1, A2, A3, A4) which are adjacent to a cross sectional surface vertical to a rotary shaft by two thereof and have two intersection spots, respectively. Two randomly adjacent arcs of the arcs have finitely or infinitely differently curved radii and a contact line combined in the intersection spots.
