Assembling method and structure of stator housing and magnet ring of motor

Abstract

The invention discloses an assembling method of a stator housing and a magnet ring of a motor. The assembling method includes the following steps that first, rigidity microparticles are added into glue, even stirring is carried out, and mixed glue is formed; second, the magnet ring is concentrically placed inside the stator housing; third, the mixed glue prepared in the first step is poured into a gap between the magnet ring and the stator housing. The invention further discloses an assembling structure of the stator housing and the magnet ring of the motor. The assembling structure comprises the stator housing and the magnet ring which are concentrically arranged, and the mixed glue is poured between the magnet ring and the stator housing. According to the assembling method of the stator housing and the magnet ring of the motor, the rigidity microparticles are added into the glue, the rigidity of the glue is improved, the easy-to-flow defect of the glue is overcome, therefore, the magnet ring and the stator housing can be effectively supported, the concentricity of the magnet ring and the stator housing can be effectively improved, meanwhile, the glue can be made to be evenly distributed on an entire bonding face, bonding strength is enhanced, and the working security of the motor is improved.

Description

technical field [0001] The invention relates to the field of motor production and manufacturing, in particular to an assembly method and structure of a motor stator shell and a magnetic ring. Background technique [0002] Epoxy glue is widely used as an adhesive in the assembly process of the motor stator shell and the magnetic ring. In order to fill epoxy glue, leave a gap of about 0.1mm width between the magnetic ring and the stator shell, such as figure 1 As shown, the magnetic ring 1 is installed in the motor stator shell 2, and the two are bonded and fixed by epoxy glue 3. Since the epoxy glue is a colloidal fluid substance, and the curing time is long, during the process of assembling the magnetic ring and the stator shell , It is very easy to cause the center of the magnetic ring to deviate from the center of the stator case. As shown in the figure, the gap 1 4a on the left is small, and the gap 2 4b on the right is large, so the motor cannot be installed. At the sa...

In order to fill epoxy glue, leave a gap of about 0.1mm width between the magnetic ring and the stator shell, such as figure 1 As shown, the magnetic ring 1 is installed in the motor stator shell 2, and the two are bonded and fixed by epoxy glue 3. Since the epoxy glue is a colloidal fluid substance, and the curing time is long, during the process of assembling the magnetic ring and the stator shell , it is very easy to cause the center of the magnetic ring to deviate from the center of the stator case. As shown in the figure, the gap 1 4a on the left is small, and the gap 2 4b on the right is large, so it is impossible to install the motor

At the same time, if figure 2 As shown, the epoxy glue 3 is easy to flow and accumulate at the bottom due to the action of gravity, resulting in an uneven glue layer, resulting in a decrease in bonding strength, and there is a safety risk in the operation of the motor
