The invention discloses a recirculating ball type electric power-assisted steering gear which is manly applied to the field of automobile steering gears. The recirculating ball type electric power-assisted steering gear comprises a motor and further comprises a planet gear speed reducer and a double-input-end recirculating ball type steering gear body. The motor is provided with an output end. The planet gear speed reducer is provided with an input end and an output end. The double-input-end recirculating ball type steering gear body is provided with a first input end and a second input end. The output end of the motor is connected with the input end of the planet gear speed reducer. The output end of the planet gear speed reducer is connected with the second input end of the double-input-end recirculating ball type steering gear body. The first input end of the double-input-end recirculating ball type steering gear body is used for connecting a steering wheel driving component. By means of the recirculating ball type electric power-assisted steering gear, a steering pump and hydraulic oil of a steering system can be omitted, and the problems that in the prior art, the energy consumption is high, the environment is polluted, the comfort is low, and safety is low are solved.
