<P>PROBLEM TO BE SOLVED: To manufacture a conical friction ring gear further compactly in size. <P>SOLUTION: A first friction cone 4 is supported by a first friction conical bearing 14 while rotating around a first friction conical bearing shaft 11, a second friction cone 5 is supported by a second friction conical bearing 18 while rotating around a second friction conical bearing shaft 15, the friction cones 4, 5 are arranged while they are applied with forces by a friction ring 9, respectively, a main bearing force 60 acting in the radial direction with respect to the friction conical bearing shafts 11, 15 is spread in a bearing main surface 41 which is fixed by both friction conical bearing shafts 11, 15, connecting torque 55 is generated between one of the friction cones 4, 5 and gear members 36, 39, and stress 56 generated by the connecting torque acts in the opposite direction with respect to the main bearing force 60 of the bearing main surface 41. <P>COPYRIGHT: (C)2012,JPO&INPIT |
