Description

Technical Field

[0001] The utility model relates to the field of industrial equipment, in particular to a motor with a stator bearing chamber. Background Art

[0002] A plastic-coated stator bearing housing is a process in which a plastic protective shell or bearing housing is formed on the stator core through injection molding or other plastic molding processes to protect the bearings and optimize their operating environment. This technology combines the advantages of metal and plastic to improve the overall performance, durability, and operating efficiency of the motor. Existing plastic-coated stator bearing housing technologies, while capable of wrapping and protecting the stator core and bearings with a plastic layer, are difficult to precisely control during motor assembly due to differences in physical properties between plastic and metal, such as thermal expansion coefficient and elastic modulus, as well as the precision limitations of the injection molding or adhesion processes themselves. This, in turn, affects the connection accuracy between the bearing housing and the stator core, posing a potential threat to the stable operation of the motor.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] like Figures 1 to 5 As shown, a motor with a stator bearing chamber includes a stator core 2, a bearing chamber 1 interconnected with the stator core 2, a plurality of openings 21 provided at one end of the stator core 2, a plurality of positioning members 11 assembled at one end of the bearing chamber 1 and used to be plugged into the openings 21, and a housing 3 provided on the bearing chamber 1; wherein, there are two bearing chambers 1 and they are plugged into the two ends of the stator core 2 respectively, and the two bearing chambers 1 have the same shape and structure, the plurality of openings 21 are distributed in an annular shape with the center of one end of the stator core 2 as the center of the circle, the plurality of positioning members 11 are distributed in an annular shape with the center of one end of the bearing chamber 1 as the center of the circle, and the positioning members 11 are positioned and plugged into the openings 21, so that the bearing chamber 1 is connected to the stator core 2 concentrically. By providing the annularly distributed openings 21 and positioning members 11, the positioning and plugging of the stator core 2 and the bearing chamber 1 are facilitated, and the accuracy of the connection between the bearing chamber 1 and the stator core 2 can be effectively guaranteed, thereby reducing the damage to the bearing during operation and promoting the stable operation of the motor.

[0028] The housing 3 is made by an injection molding process, so that the stator core 2 is embedded in the housing 3. The injection molding process not only improves the integrity of the structure and increases the concentricity of the stator core 2, but also enhances the electrical insulation and rust resistance of the stator core 2.

[0029] The number of the positioning members 11 and the number of the openings 21 are the same, that is, there are at least three positioning members 11 . By providing the same number of positioning members 11 and the number of the openings 21 , the structural strength of the stator core 2 and the bearing chamber 1 is enhanced.

[0030] The bearing chamber 1 is supported by the overmolding process. In this embodiment, the bearing chamber 1 is made of metal material as raw material and then subjected to the overmolding process. One end of the shell 3 is provided with an assembly groove 31 for clamping the stator core 2. The shell 3 and the assembly groove 31 are an integrally formed structure, and the assembly groove 31 is provided with a snap 32 for clamping with the overmolding groove 12. By providing the assembly groove 31 and the snap 32, the firmness of the connection structure between the stator core 2 and the bearing chamber 1 is further enhanced, and the connection position of the bearing chamber 1 on the shell 3 can be effectively limited to prevent it from falling off axially. It is worth noting that the material of the shell 3 is plastic. The plastic material has certain elasticity and damping properties, which can absorb and reduce the vibration and noise during the operation of the motor to a certain extent, thereby improving the running stability and comfort of the motor.

[0031] A plurality of rubber-coated grooves 12 are provided on the circumferential side of the bearing chamber 1, and at least three rubber-coated grooves 12 are provided. By providing the rubber-coated grooves 12, the connection structure between the bearing chamber 1 and the assembly groove 31 is further fixed to prevent the bearing chamber 1 from falling off from one end of the stator core 2. At the same time, by providing multiple rubber-coated grooves 12, the sealing effect of this embodiment can be further enhanced to prevent external impurities such as dust and moisture from entering the interior of the stator core 2 and affecting the performance and life of this embodiment.

[0032] It is worth noting that the rubber-encapsulating grooves 12 are formed by lathe processing. The lathe processing process ensures the inner diameter and spacing of the rubber-encapsulating grooves 12, further improving the assembly accuracy of this embodiment.

[0033] Working principle: The two bearing chambers 1 are respectively inserted into the two ends of the stator core 2 through the positioning piece 11 and the opening 21, so that the bearing chambers 1 are connected concentrically with the stator core 2. The stator core 2 and the bearing chamber 1 are then injection molded to form a shell 3, and assembly grooves 31 for wrapping the bearing chamber 1 are formed at both ends of the shell 3.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
