Detailed Description

Specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While specific embodiments of the invention are shown in the drawings, it will be understood that the invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

It should be noted that certain terms are used throughout the description and claims to refer to particular components. As one skilled in the art will appreciate, various names may be used to refer to a component. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The following description is of the preferred embodiment of the invention, and is made for the purpose of illustrating the general principles of the invention and not for the purpose of limiting the invention. The protection scope of the present invention is subject to the limitations defined by the appended claims.

The embodiment provides a permanent magnet roller stator goes into rotor frock structure, as the frock structure sketch map shown in fig. 1, includes:

the hollow pipe 1 is detachably sleeved on the permanent magnet roller stator shaft assembly;

rib plates 2 are shown in figure 2 and are in a front view of the tool, and a plurality of rib plates 2 are fixedly sleeved on the outer peripheral surface of one end of the hollow pipe 1 through welding and are uniformly distributed on the outer peripheral surface of one end of the hollow pipe;

and the aluminum guide bars 4 are embedded on the outer peripheral surface of the sleeve 3 in a one-to-one correspondence manner with the rib plates 2.

The aluminum conducting bars 4 are not magnetic conducting, have good guiding effect and protecting effect, and enable the stator assembly to smoothly enter the rotor assembly.

In the preferable embodiment of the tool structure for the permanent magnet roller stator to enter the rotor, a plurality of rectangular grooves corresponding to the rib plates 2 are arranged on the outer peripheral surface of the sleeve 3, and the length direction of each groove is in the axial direction.
