Abstract: <P>PROBLEM TO BE SOLVED: To prevent the deterioration of the torque transmitting efficiency of a wave gear device during high-speed rotation.  <P>SOLUTION: In a wave motion generator 4 for the wave gear device 1, only short axis sides 51, 52 including both ends 51a, 52a of an elliptical short axis Lmin are formed of raw materials having greater linear expansion coefficients than the other portion. When the temperature of a rigid cam plate 5 rises during the input of high-seed rotation, the short axis sides 51, 52 are thermally expanded than the other portions and a ball 10 other than several balls 10b on the side of the short axis Lmin of a wave bearing 7 is put into a tight state to form such a locked state that the wave bearing 7 is rotated integrally with the rigid cam plate 5. This avoids or reduces the agitating resistance of lubricant caused by the high-speed rolling motion of the ball 10 during the input of high-speed rotation to prevent or suppress the deterioration of the torque transmitting efficiency resulting from the agitating resistance.  <P>COPYRIGHT: (C)2009,JPO&INPIT
