Abstract:
A rotary power transmission apparatus which has an input rotary member and an output rotary member arranged on an axis eccentric from that of said input rotary member and rotated by a rotary power transmitting from the input rotary member, comprising:first drive means for turning said input rotary member on its center axis;a cylindrical member arranged around outer circumference of said input rotary member and said output rotary member and made rotatable on an axis eccentric from those of said input rotary member and said output rotary member;a first intermediate rotary member made rotatable on its axis in engagement with the outer circumference of said input rotary member and an inner circumference of said cylindrical member to transmit a torque between said input rotary member and said cylindrical member;a second intermediate rotary member made rotatable on its axis in engagement with the outer circumference of said output rotary member and the inner circumference of said cylindrical member to transmit the torque between said cylindrical member and said output rotary member; anda relative phase changing mechanism for changing relative phases in the direction of rotation between said first intermediate rotary member and said second intermediate rotary member by revolving the second intermediate rotary member along the inner circumference of said cylindrical member.
