Problems solved by technology

[0002] The motor rotor is movably installed between the upper and lower covers through the positioning hole processed in the middle of the upper and lower covers. Due to the non-concentricity of the centerlines of the positioning holes of the upper and lower covers during the actual processing and installation process, the installed motor rotor produces eccentric rotation and beating , resulting in shortened service life of the motor, increased noise and increased vibration during rotation

Abstract

A small-power motor comprises a rotor, wherein a rotor is movably arranged between an upper cover and a lower cover, through holes and upper positioning convex shoulders are processed in two ends of the upper cover, threaded holes and lower positioning convex shoulders are correspondingly processed in the lower cover, the upper cover and the lower cover are fixed on a support by bolts, spherical-surface shaft sleeve positioning holes and counter holes are formed in middle parts of the upper cover and the lower cover, counter shoulders are arranged in the counter holes, spherical-surface shaftsleeves are arranged in the shaft sleeve positioning holes and are provided with elastic baffle sheets in a matching way, the elastic baffle sheets are limited by the counter shoulders and riveting grooves, and the riveting grooves are processed in the circumferences of the counter holes. The spherical-surface shaft sleeves are used for installing a rotor, and the problem that the spherical-surface shaft sleeve positioning holes of the upper cover and the lower cover are not concentric after actual processing can be solved; and meanwhile, the motor has the advantages of safety, reliability, low noise, good starting performance, long service lifetime and the like.

Description

technical field [0001] The invention relates to a small power motor. Background technique [0002] The motor rotor is movably installed between the upper and lower covers through the positioning holes processed in the middle of the upper and lower covers. Due to the non-concentricity of the centerlines of the positioning holes of the upper and lower covers during the actual processing and installation process, the installed motor rotor produces eccentric rotation and beating , which will eventually lead to a shortened service life of the motor, greater noise and increased vibration during rotation. [0003] A low-power motor mentioned in the present invention solves the above-mentioned problems. Contents of the invention [0004] Aiming at the deficiencies in the above problems, the present invention provides a low-power motor. [0005] To achieve the above object, the present invention provides a low-power motor, comprising: [0006] The upper cover, the two ends of th...
