Speed-reducing electric motor module, speed reducing method for electric motor module and physical assistance device

Abstract

Disclosed in the present invention is an efficient and rapid speed-reducing electric motor module, comprising a driving end and a rotary output shaft, wherein the driving end comprises a lead screw and a lead screw nut, one end of the lead screw being provided with a matched lead screw, which can be connected to a power interface of a prime mover for driving the lead screw to rotate; when the lead screw drives the lead screw nut to move linearly, the lead screw nut rotates about the lead screw under the guidance of a guide rail; and the lead screw nut drives the rotary output shaft to rotate during the rotation process thereof. The present invention provides a new speed reducer and a new speed reducing method, such that the rotation speed is reduced, and the output torque is thus improved.
