Abstract
Title: FIRMLY-FIXED FITTING STRUCTURE BETWEEN A STATOR CORE AND A SHELL Abstract A firmly-fixed fitting structure between a stator core and a shell, the stator core and the shell being fixed by glue, characterized in that multiple bosses, which are arranged at intervals, are provided in the circumferential direction of a fitting surface on which the stator core and the shell are fitted, and the bosses are resisted against an inner side of the shell to form a gap between the adjacent bosses; the length of the bosses is consistent with the thickness of the stator core.

DESCRIPTION
FIRMLY-FIXED FITTING STRUCTURE BETWEEN A STATOR CORE
AND A SHELL
Technical Field of the Invention
The present invention relates to a firmly-fixed fitting structure between a stator core and a shell.
Background of the Invention
During the design of a motor, the assembly issue of the motor stator core and the motor shell must be considered. It is necessary to ensure that the stator and the shell are assembled tightly, so that the relative rotation and axially relative sliding of the stator and the shell are avoided when the motor runs. At present, the stator core and the motor shell are usually fixed by glue. However, insufficient firmness of the fixation of the stator core and the motor shell often occurs since the adhesion of the glue cannot last for a very long period of time.
Summary of the Invention
An objective of the present invention is to provide a firmly-fixed fitting structure between a stator core and a shell, which can make the fitting and fixation of the stator core and the motor shell more firm.
To realize this purpose, the present invention employs the following technical solution. A firmly-fixed fitting structure between a stator core and a shell is provided, the stator core and the shell being fixed by glue, characterized in that multiple bosses, which are arranged at intervals, are provided in the circumferential direction of a fitting surface on which the stator core and the shell are fitted, and the bosses are resisted against an inner side of the shell to form a gap between the adjacent bosses. 1 2016101692 19 Sep 2016
Bump structures, spaced apart from each other, are formed on a surface of the stator core, so that a sufficient gap is left between the surface of the stator core and an inner wall of the shell to receive the glue. As a result, the stator core and the shell are fixed more firmly; the length of the bosses is consistent with the thickness of the stator core.
The present invention has the advantages that the stator core and the motor shell are fixed firmly, and the fitting strength between the stator core and the motor shell can be ensured.
Brief Description of the Drawings
Fig. 1 is a structure diagram of the present invention; and
Fig. 2 is an enlarged view of part A of Fig. 1.
Detailed Description of the Invention
As shown in Fig. 1 and Fig. 2, the fitting structure between a stator core and a shell of the present invention includes a stator core 1 and a shell 2, and the stator core 1 and the shell 2 are fixed by glue.
Twelve bosses, which are arranged at intervals, are provided in the circumferential direction of a fitting surface on which the stator core 1 and the shell 2 are fitted, and a gap 4 is formed between the adjacent bosses. The bosses are arranged in six groups, and the shell has six grooves corresponding to each group of bosses. The six groups of bosses are evenly arranged, at intervals, on a fitting surface on which the stator core 1 and the shell 2 are fitted. The length of the bosses 3 is consistent with the thickness of the stator core. And, the thickness of the bosses 3 is 1 mm, so that the thickness of the gap 4 is 1 mm. 2
