specific Embodiment approach

[0010] As shown in the figure, the bearing seat 1 and the grommet 3 are combined into one, and are injection molded at one time; the bearing seat 1 and the copper-based oil-impregnated bearing 2 are cooled to a certain temperature by the plastic part of the bearing seat 1 during injection molding, and the copper The oil-based bearing 2 is quickly pressed into the plastic part when it drops to a certain temperature, and the copper-based oil-impregnated bearing 2 is embedded in the bearing seat 1 after cooling, and the automatic centering function is realized by the outer diameter arc surface of the copper-based oil-impregnated bearing 2 , so as to achieve the automatic centering and alignment of the motor rotor inside the stator; each pin root 5 is made with an arc to clear the root 4 to avoid burrs.

Abstract

The invention discloses a self-aligning bearing holder for a tubular motor. A bearing holder body and a protection sleeve are combined into one and are formed through one-shot injection molding. After injection molding, a copper base oil-impregnated bearing is rapidly pressed into a plastic component when the plastic component cools to a certain temperature. After the cooling process, the copper base oil-impregnated bearing is embedded into the bearing holder body and the exterior diameter arc face of the copper base oil-impregnated bearing can help fulfill the self-aligning function. The Pin roots are provided with an arc clear root each so as to prevent the generation of burrs.

Description

technical field [0001] The invention relates to an automatic self-aligning bearing seat of a tubular motor, which is mainly used in the installation and assembly of the motor stator and rotor of the tubular motor. Background technique [0002] Due to the material of the existing bearing seat is engineering plastics, there will be certain deformation during casting, which cannot ensure the concentricity of the product well, resulting in unstable magnetic field, high noise, and serious motor sweeping; the existing bearing seat and The motor coil sheath is two separate parts. After installation, the length of the motor is relatively long. The longer the motor, the more difficult it is to ensure the concentricity requirements; Burrs are generated during slot assembly, resulting in a gap between the sleeve and the stator after assembly. Contents of the invention [0003] In view of the problems and shortcomings found in the connection and fixing method of the motor stator and ...
