According to the spiral bevel gear electric steering engine, a first transmission chain and a second transmission chain are perpendicularly connected with an output shaft, parts of the first transmission chain and the second transmission chain are symmetrically arranged along the perpendicular symmetric face of the output shaft, and the first transmission chain comprises a first permanent magnet synchronous motor, a first planet wheel, a first inner gear ring and a first small spiral bevel gear; a cylindrical gear is arranged at the output end of the first permanent magnet synchronous motor and serves as a sun gear to be meshed with a first planet gear, a first inner gear ring is located on the outer ring of the first planet gear and meshed with outer teeth of the first planet gear, and the first planet gear is coaxially and fixedly connected with a first small spiral bevel gear. The output shaft is provided with a large spiral bevel gear meshed with the first small spiral bevel gear; similarly, the second transmission chain comprises a second permanent magnet synchronous motor, a second planet wheel, a second inner gear ring and a second small spiral bevel gear. The bearing capacity and the transmission rigidity are improved, and high transmission efficiency can be achieved under the heavy-load and large-torque working condition.
