The present invention relates to the field of transmission mechanisms, particularly to a mechanism capable of adjusting rotation directions and rotation speeds of an inner ring and an outer ring of a rotation bearing. The mechanism comprises a base (103), a main bearing set (100,130) penetrating through the base (103), a plurality of support rotation bearing (104,105,106) installed on the base (103) and positioned on the periphery of the main bearing set (100, 130), and a transmission mechanism, wherein the main bearing set (100, 130) comprises at least a main bearing (101,131), the main bearing (101, 131) comprises an inner ring (101E, 111) and an outer ring (101A, 112), the inner ring (101E or 111) and a shaft (102) are connected, the mechanism further comprises a plurality of rolling assemblies (101D) in an application of a contact type bearing, and the mechanism further comprises a fluid (115) in an application of a non-contact type bearing. According to the present invention, the transmission mechanism is additionally arranged in the rotation bearing, such that the inner ring and the outer ring of the bearing perform proper rotation.
