Space revolution type large driving mechanism

The invention discloses a space revolution type large driving mechanism. A rolling ring electric transmission mechanism is fixedly connected with a lower end face flange; the guide rail is connected with the upper end face flange through a rotary supporting mechanism and can achieve rotary motion by means of a rolling amplitude in the rotary supporting mechanism. The lower end face flange and the guide rail are clamped into a whole through the clamping and locking mechanism. The driving part is fixedly installed on the upper end face flange, the tail end gear is meshed with the guide rail to achieve revolution around the guide rail so as to drive the upper end face flange to rotate, the rolling ring electric transmission mechanism is connected with the upper end face flange through the rolling ring connecting piece, and common rotation of the rolling ring electric transmission mechanism, the upper end face flange and an external load is achieved. And the power generated from the outside is transmitted to the
