PCT No. PCT/SE95/00815 Sec. 371 Date Feb. 11, 1997 Sec. 102(e) Date Feb. 11, 1997 PCT Filed Jul. 10, 1995 PCT Pub. No. WO96/05451 PCT Pub. Date Feb. 22, 1996An eccentric gear comprises two differently large gear rings (6, 7), of which an outer ring (6) has a certain number of inwardly directed teeth and an inner ring (7) has a smaller number of outwardly directed teeth, of which only a few engage with the outer gear ring, in that the inner gear ring is eccentrically mounted in bearings. The inner gear ring (7) is integrated with a casing part (8) whose geometrical axis of rotation (A) is oblique relative to an axis of symmetry (B) through the center of the outer gear ring (6). During the generation of the inner gear ring, the casing part is submitted to a nutating motion, during which the axis of rotation (A) of the casing part moves as a generatrice along an imaginary cone, around a cone apex (C) that is axially distanced from the gear rings (6, 7). In a region that is equally distanced from the gear rings as the cone apex (C), the casing part is associated with a gear ring (12) that is ready to be led into engagement with a complementary second gear ring on the driven element of an application object in order to, jointly with the latter, form a force transmitting unit situated substantially in a plane (D-D) extending perpendicularly to said axis of symmetry, in which plane the cone apex (C) is located. |
