The invention discloses a pure electric mechanical steering gear for a medium-sized commercial vehicle. The pure electric mechanical steering gear comprises an upper shell and a lower shell, the uppershell and the lower shell are connected and fixed through bolts. A steering screw rod is arranged in the lower shell; a steering nut is arranged on the outer side of the steering screw; spiral raceway transmission is formed between the steering screw and the steering nut through a steel ball; a gear groove is formed in the outer side of the steering nut; a gear sector shaft clamped with a gear groove of the steering nut is arranged in the lower shell; and a gear for driving the steering screw to rotate is arranged on one side of the lower end in the lower shell. According to the pure electricmechanical steering gear for a medium-sized commercial vehicle, the gear is simple in structure, the cost and energy consumption is reduced greatly, a light commercial vehicle with a small chassis space can be helped easily achieve intelligent steering control without modifying any part of a cockpit, the functions of steering hand power speed-following adjustment, automatic alignment, middle position keeping, road surface bumping filtering and the like are realized, and the driving experience of a driver is improved.
