The invention relates to a cylindrical gear and planet wheel combined type electric power-assisted recirculating ball steering gear. The cylindrical gear and planet wheel combined type electric power-assisted recirculating ball steering gear is characterized in that a power unit assembly and a primary speed reducer assembly are fixed together with a mechanical recirculating ball steering gear assembly; the cylindrical gear reducer assembly is assembled between the gearbox side cover assembly and the mechanical recirculating ball steering gear; the gearbox side cover assembly and the mechanical recirculating ball steering gear assembly are fixed together; the inner gear ring and the mechanical recirculating ball steering gear assembly are fixed together; the steering arm shaft assembly with the planet wheel speed reducing mechanism is assembled on the mechanical recirculating ball steering gear assembly through an arm shaft input end bearing and an arm shaft output end bearing and then is axially fixed through a steering arm shaft fixing nut. A traditional mechanical recirculating ball steering gear is effectively combined with a gear and a planet wheel, electric power steering of a commercial vehicle can be achieved, and the electric power steering device has the advantages of being efficient, capable of saving energy and easy to arrange the whole vehicle.
