The utility model provides a combined double-row cylindrical roller bearing for a wind power gear box, relates to the technical field of roller bearings, and aims to solve the problems that a bearing cannot be quickly fixed in a machine and needs to be fixed in a manual welding manner. The roller bearing consists of a connecting structure, a self-locking structure, a limiting structure and a rolling device; self-locking structures are mounted on the connecting structure, and the self-locking structures are arranged in two groups; the self-locking structure comprises an elastic piece, and the two ends of the elastic piece are fixedly connected with the clamping plate and the fixing plate respectively. The limiting structure is fixedly connected into the connecting structure, and a rolling device is movably connected into the limiting structure. The rolling device is arranged in the connecting structure and is in lap joint with the connecting structure. Due to the arrangement of the self-locking structure, when
