Description

Technical Field

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

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The main functions of an electric motor include electrical energy conversion, power output, and precise control. The core components of an electric motor are the stator, rotor, and housing. The housing is usually formed by combining a middle housing with two end covers. Bearings are installed inside the end cover housings through interference fit. Existing end cover housings are usually directly attached to the middle housing and fixed with bolts, resulting in low connection strength. Furthermore, the structural strength at the edges of existing motor end covers is low. Utility Model Content

[0003] To overcome the shortcomings of the existing problems mentioned above, this utility model provides a reinforced motor end cover.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a reinforced motor end cover, the motor end cover is set on the motor housing, the motor end cover includes an end cover body, an external thread is opened on the outer side of the end cover body, an inner ring is provided on the end cover body inside the external thread, a lightweight groove is opened between the external thread and the inner ring, a plurality of first reinforcing blocks are evenly distributed in the lightweight groove, a countersunk hole penetrating the end cover body is opened in the middle of the first reinforcing block, a balance adjustment groove is opened on the side of the motor housing away from the lightweight groove, a second reinforcing block corresponding to the position of the first reinforcing block is provided in the balance adjustment groove, a central housing is provided in the middle of the inner ring, a through hole is opened on the central housing, during installation, the bearing of the inner shaft of the motor is connected through the through hole, the external thread is initially connected to the motor housing, and the tightness between the motor housing and the external thread is adjusted by bolts and countersunk holes.

[0005] Preferably, an arc-shaped heat dissipation blade is provided between the middle housing and the inner ring, and heat is discharged through the arc-shaped heat dissipation blade when the motor is working.

[0006] Preferably, a threaded protrusion is provided at the middle position of the same side as the balance adjustment groove on the end cap body, which facilitates connection with external equipment.

[0007] The beneficial effects of this utility model are that the external thread facilitates initial positioning and strengthens the connection between the end cover and the motor housing. A lightweight groove is provided on the inner side of the end cover body, which reduces costs and lightens the weight of the end cover body. A balance adjustment groove is provided on the outer side of the end cover body, which allows the balance mud to be stuck in the balance adjustment groove for easy adjustment of balance.

[0010] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0011] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Specific Implementation

[0012] like Figure 1-2 The diagram shows a reinforced motor end cover, which is mounted on a motor housing 1. The motor end cover includes an end cover body 2, with an external thread 3 on the outer side of the end cover body 2. An inner ring 4 is provided inside the external thread 3 and on the end cover body 2. A lightweight groove 5 is provided between the external thread 3 and the inner ring 4. Several first reinforcing blocks 6 are evenly distributed in the lightweight groove 5. A countersunk hole 7 penetrating the end cover body 2 is provided in the middle of the first reinforcing blocks 6. A balance adjustment groove 10 is provided on the side of the motor housing 1 away from the lightweight groove 5. A second reinforcing block 11 corresponding to the position of the first reinforcing block 6 is provided in the balance adjustment groove 10. A central housing 8 is provided in the middle of the inner ring 4. A through hole 9 is provided on the central housing 8. During installation, the motor housing 1 is initially connected to the external thread 3, and the tightness between the motor housing 1 and the external thread 3 is adjusted by bolts and the countersunk hole 7.

[0013] An arc-shaped heat dissipation blade 12 is provided between the middle housing 8 and the inner ring 4. When the motor is working, heat is discharged through the arc-shaped heat dissipation blade 12.

[0014] Working principle: During installation, the end cover body 2 is connected to the motor housing 1 through the external thread 3, and the fixing strength is strengthened by bolts and countersunk holes 7 to complete the installation. When the balance is tested and adjusted, the balance mud sticks in the balance adjustment groove 10, so that the motor can keep running smoothly. The bearing of the motor and the end cover body 2 are interference fit. If the bearing has a problem, the push rod is used to push the bearing out through the through hole 9 for disassembly. Specific Implementation

[0015] like Figure 3-4 As shown, this embodiment is largely the same as the first embodiment in terms of structure. The difference is that a threaded protrusion 13 is provided in the middle of the same side as the balance adjustment groove 10 of the end cap body 2, which facilitates connection with external equipment.

[0016] This design is ingenious. The external thread facilitates initial positioning and strengthens the connection between the end cover and the motor housing. The inner side of the end cover body has a lightweight groove, which reduces cost and weight. The outer side of the end cover body has a balance adjustment groove, which allows the balance mud to be adhered to for easy adjustment of balance. Reinforcing blocks are set in both the lightweight groove and the balance adjustment groove, which effectively improve the structural strength at the edge of the end cover. In addition, when the motor is working, heat is dissipated through arc-shaped heat dissipation fins.

[0017] 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.
