A transmission mechanism (1) comprises a supporting frame (11); a transmission shaft (12) mounted on the supporting frame (11), the power generated by a power part (4) being transmitted to a driven part (6) via the transmission shaft (12); and a bearing assembly (13) mounted on the transmission shaft (12). The bearing assembly (13) comprises a flexible bearing (14) and a support bearing (15). The flexible bearing (14) has an outer ring (16) and an inner ring (17), the inner surface of the outer ring (16) is a spherical surface, and the inner ring (17) is rotatably mounted on the outer ring (16) around the spherical center of the spherical surface. The outer ring (16) is fixed on the inner wall of the supporting frame (11), and the inner ring (17) is mounted on the support bearing (15), and the support bearing (15) is assembled on the transmission shaft (12). The supporting frame (11) drives the bearing assembly (13) supporting the transmission shaft (12) to deflect after the supporting frame is bent. Because of the rotatable connection between the outer ring (16) and the inner ring (17) of the flexible bearing (14) in the bearing assembly (13), the supporting frame (11) is prevented from transmitting the bending stress generated by bending to the transmission shaft (12), and therefore the damage to the transmission shaft (12) is avoided. |
