Description

Technical Field

[0001] This utility model relates to the field of motor end cover technology, and in particular to a lightweight heat dissipation type motor end cover. Background Technology

[0002] Electric motors, as indispensable equipment in modern industry and daily life, are widely used in various power tools, home appliances, automobiles, robots, and other fields. In the design and manufacturing process of electric motors, the end cap is a crucial component. It not only serves to fix and protect the internal structure of the motor but also affects its heat dissipation performance and balance. Traditional motor end cap designs often require a trade-off between structural strength, heat dissipation performance, and weight. For example, to improve structural strength, the end cap may need to use thicker materials, but this increases the overall weight of the motor and reduces heat dissipation performance, thereby reducing the motor's energy efficiency. To address these issues, this application provides a motor end cap designed to balance structural strength, heat dissipation performance, and weight, thereby improving the overall performance and reliability of the motor.

[0011] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0013] according to Figures 1-4As shown, a reinforced motor end cover includes a spindle 1, a stator 2 mounted on the spindle 1, bearings 3 at both ends of the spindle 1, and a rotor mounted on the outer side of the stator 2. The rotor includes a housing 4 and an end cover 5. The end cover 5 includes an inner ring 51 and an outer edge 52, which refer to two positions on the end cover 5. A ring-shaped balance groove 53 is provided at the front end of the outer edge 52. The balance groove 53 is used to add balancing mud to adjust the rotor's balance. Compared to a traditional end cover, the balance groove 53 has a larger area. The thinner edge effectively reduces the weight of the end cover, decreases motor energy consumption, and improves energy efficiency. The balance groove 53 contains evenly distributed front reinforcing blocks 54 to strengthen the structural strength of the outer edge 52 of the end cover 5. The front reinforcing blocks 54 also have fixing holes 55. The rear end of the outer edge 52 is provided with a weight-reducing groove 56 and a limiting end face 57. The weight-reducing groove 56 reduces the weight of the end cover, and the limiting end face 57 limits its position during installation and docking with the housing 4. The limiting end face 57 is located on the outer ring of the weight-reducing groove 56. All grooves 56 are arranged in a ring on the rear side of the outer edge 52. The limiting end face 57 is located on the outer side near the outer edge. The weight-reducing groove 56 is located on the inner side near the inner ring 51. A rear reinforcing block 58 is provided in the weight-reducing groove 56. The position of the rear reinforcing block 58 corresponds to that of the front reinforcing block 54. The arrangement of the front reinforcing block 54 and the rear reinforcing block 58 facilitates the setting of the fixing hole 55. At the same time, the mutual cooperation between the front reinforcing block 54 and the rear reinforcing block 58 can effectively enhance the structural strength and stability of the outer edge of the end cap. The fixing hole 55 is provided through the front reinforcing block 54 and the rear reinforcing block 58. On 58, bolts are used to connect and fix the end cover 5 to the housing 4 through the fixing holes 55; the surface of the outer edge 52 is provided with a plurality of heat dissipation fins 59 arranged in a ring, the front end of the heat dissipation fins 59 is set with an arc structure, the setting of the heat dissipation fins 59 can improve the structural strength of the outer edge 52, and also help dissipate heat, improve the working efficiency and stability of the motor, and the arc structure at the front end can reduce weight, further realizing lightweighting; the inner ring 51 is provided with a mounting groove 510 for connecting with the bearing 3, and the front end of the mounting groove 510 is provided with a through hole 511.

[0014] The end cap 5 includes a front end cap and a rear end cap. The front end cap has a threaded protrusion 6 at the front end of its inner ring 51. The front end cap and the rear end cap have the same structure, except that the front end cap 5 has a threaded protrusion 6 at the front end, while the rear end cap does not have a threaded protrusion 6 at the front end.

[0015] A plurality of arc-shaped blades 512 are provided between the inner ring 51 and the outer edge 52. The arc-shaped blades 512 are set at a certain angle, which helps to guide the flow of cooling air and improve heat dissipation efficiency.

[0016] The fixing hole 55 is configured as a stepped hole structure.

[0017] This design is ingenious. The balance slot and weight reduction slot effectively reduce the weight of the end cover, thereby reducing the weight of the motor rotor, reducing the energy consumed during operation, and improving the energy efficiency of the motor. At the same time, the heat dissipation fins and reinforcing blocks maintain the original functionality, such as heat dissipation and fixation, while also enhancing the rigidity and deformation resistance of the end cover, effectively strengthening the lightweight end cover.

[0018] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
