<P>PROBLEM TO BE SOLVED: To provide a gear transmission mechanism not requiring securement of moving space of a sensor detecting a rotational frequency of a rotating member supported by a movable frame. <P>SOLUTION: The gear transmission mechanism has plural sets of continuously variable transmission units 6 comprised by meshing a plurality of non-circular gears 20-38 respectively attached to a plurality of rotating members 7, 8, and 9, a fixed frame 10 supporting the plurality of rotating members 7 and 8, and a movably composed movable frame 15 supporting the rotating member 9. By moving the movable frame 15, a gear ratio between the rotating member 7 of an input side and the rotating member 9 of an output side can be steplessly changed. It has a displacement detecting device 44 detecting a displacement of the rotating member 9, and a lubricant supply amount controlling device controlling a supply amount of a lubricant to be supplied to a bearing 18 of the rotating member 9 on the basis of the displacement of the rotating member 9. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
