A compact electric steering gear is characterized in that a worm is radially limited and fixed in a worm hole formed in a speed reducing mechanism shell through bearings at two ends, the worm is meshed with a worm gear in a tooth form, the worm is matched with an electric driving unit through an end face tooth form, and the worm gear is sleeved on an input shaft and a steering screw assembly in an interference manner; the baffle is radially limited in a clamping groove in the speed reducing mechanism shell, a clamping position in the axial direction of the baffle is matched with a clamp of the sensor for limiting, and the sensor is welded on the input shaft and the steering screw assembly and is connected with a corresponding terminal of the electric driving unit through a signal wire harness; the steering nut assembly and the input shaft are in connection transmission with the steering screw assembly through an inner ballistic steel ball, and the steering nut assembly and the steering arm shaft assembly are in matched transmission through a gear sector. The compact type electric steering gear has the advantages of being compact in structure, novel in structure and convenient and fast in axial clearance adjustment.
