The invention relates to the technical field of steering equipment for vehicles, and provides a circulating ball type electric power steering gear which comprises a mechanical steering gear, a speed reducer, an integrated motor controller and a sensor. The mechanical steering gear is provided with a steering gear shell and a steering screw, and the speed reducer is provided with a speed reducer shell. The steering gear shell and the speed reducer shell are fixed in a detachable connection mode. A steering input shaft and a worm wheel shaft are arranged in the speed reducer and are flexibly connected through an elastic torsion bar; and a sensor is arranged at the joint of the input end of the steering input shaft and the output end of the worm wheel shaft. The Hela torque sensor capable ofoutputting a torque signal and a corner signal at the same time is adopted, induction is more sensitive, and the signals are more stable and reliable.
