Abstract
The utility model discloses a single-bearing motor structure. The single-bearing motor structure comprises a casing and a rotating shaft of a rotor portion, wherein at least one end of the rotating shaft extends out of the housing, and a double-groove bearing is mounted in a position where the rotating shaft penetrates through the housing to support the rotating shaft. The double-groove bearing comprises a bearing body, a transverse channel is arranged along the axial direction so that the rotating shaft can penetrate through bearing body via the transverse channel, and two separate annular grooves are arranged along the channel in the bearing body to form a three-section support portion. According to the utility model, the bearing is mounted at one end of the rotating shaft of the motor to form the single-bearing structure, compared with a prior double-bearing structure, one end bearing is saved, so that assembling efficiency is improved; and the double-groove bearing is employed, so that operational performance of the motor is the same as that of the motor with the prior double-bearing structure, which has the advantages of reasonable structure, safe and reliable performance, and the like.
