Direct-driving motor with single-bearing structure

Abstract

The invention discloses a direct-driving motor with a single-bearing structure. The direct-driving motor comprises a motor shell, a stator component, a rotor component, a front flange and a back flange, wherein one end of the motor shell is connected with the front flange; the other end is connected with the back flange; a middle part of the back flange is provided with a back through hole; one side of the back through hole is provided with a bearing room; a rotary shaft in the rotor component is connected with a bearing inner ring; one end of the rotary shaft extends from the back through hole of the back flange, and a bearing outer ring of the rotary shaft is connected with the bearing room; the middle part of the front flange is provided with a front through hole; the other end of the rotary shaft extends from the front through hole of the front flange; the front flange is provided with a first through screw hole extending along a radial direction; the rotary shaft is provided witha second screw hole; and the first screw hole in the front flange and the second screw hole in the rotary shaft are fixedly connected with each other through a screw. Through adoption of the direct-driving motor, the position of the rotary shaft can be adjusted through the activity of a single bearing; the mounting matching degree with a matched client is improved; and the matching degree is low.The direct-driving motor can be applied to an environment in which a large deviation exists in the butt-joint position.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a direct drive motor with a single bearing structure. Background technique [0002] Usually the motor adopts a double bearing structure, that is, both the front flange and the rear flange of the motor are connected with the outer ring of the bearing, and the two ends of the rotating shaft of the rotor assembly are respectively connected with the inner ring of the bearing on the front flange and with the inner ring of the bearing on the rear flange. The ring is connected, so that the position of the rotating shaft is fixed and cannot be adjusted. When the rotating shaft of the motor is assembled and docked with the supporting motor, it cannot be used in an environment where there is a large deviation in the assembly and docking position, and the cooperation is difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
