The utility model discloses a squirrel cage rotor structure which comprises a rotating shaft and a rotor core on the rotating shaft, squirrel cage bars are arranged on the rotor core, pressing fingers, end rings and pressing rings are arranged on the rotating shaft, the pressing fingers are arranged on two sides of the rotor core, the end rings are arranged on the outer sides of the pressing fingers, the squirrel cage bars are arranged on the rotor core and the pressing fingers in a penetrating mode, and the end portions of the squirrel cage bars are connected with the end rings. A pressing ring is arranged on the outer side of the end ring. The laminated squirrel-cage asynchronous motor structure without the retaining ring has the advantages that the laminated squirrel-cage asynchronous motor structure without the retaining ring can bear large centrifugal force, has thermal expansion stress release spaces in the axial direction and the radial direction, can operate in high-temperature and high-rotating-speed
