Description

Technical Field

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

[0002] Motor end covers are covers installed at both ends of the motor to seal the inside of the motor. The end covers also have holes for the rotation of the motor shaft. After installation, the end covers are usually only removed during maintenance.

[0003] In order to better support the shaft, the end cover of the motor is usually reinforced with reinforcing ribs. However, the reinforcing ribs on the motor end cover can easily affect the installation inside the motor, causing interference with the motor's internal components. In addition, the weight of the end cover will increase, making disassembly and assembly more inconvenient. Utility Model Content

[0004] To address the issue that, in the existing technology, motor end covers are typically reinforced with reinforcing ribs to better support the rotating shaft, but these ribs can interfere with the internal installation of the motor and increase the weight of the end cover, making disassembly and assembly inconvenient, this application provides a lightweight motor end cover.

[0005] A lightweight motor end cover includes a cover body, a bushing at the center of the cover body, the bushing being integrally formed with the cover body, the bushing being used to mount the motor shaft, a connecting plate at the edge of the cover body, the connecting plate being arranged circumferentially around the cover body, the connecting plate having multiple connecting holes for connecting to the motor housing, and multiple reinforcing ribs on the side of the cover body near the motor housing, the reinforcing ribs being arranged from the bushing toward the connecting plate, with an installation space left between the reinforcing ribs and the connecting plate.

[0006] By adopting the above technical solution, while setting the reinforcing ribs, a certain installation space is left between the reinforcing ribs and the connecting plate. This can reduce interference and facilitate installation inside the motor housing. At the same time, it can shorten the length of the reinforcing ribs, thereby reducing the overall weight of the cover and further improving the ease of disassembly and assembly.

[0007] Optionally, the reinforcing ribs are arranged at equal intervals along the axial direction of the bushing, and each reinforcing rib has the same length.

[0008] By adopting the above technical solution, the reinforcing ribs are evenly spaced along the axial direction of the bushing, and each reinforcing rib has the same length. This ensures that the strength of the motor end cover is evenly distributed at different positions, effectively improving structural stability and avoiding deformation or damage caused by uneven local stress. At the same time, the design of equal spacing and equal length makes the manufacturing process simpler and easier for mass production.

[0009] Optionally, the end of the reinforcing rib near the bushing is fixedly connected to the bushing.

[0010] By adopting the above technical solutions, the overall rigidity and stability of the structure are enhanced, preventing loosening and deformation caused by vibration or impact, and improving the safety and reliability of the motor during operation. At the same time, this fixing method also helps to improve production efficiency and simplify the assembly process.

[0011] Optionally, the reinforcing rib is provided with a supporting inclined surface, wherein the side of the supporting inclined surface closer to the bushing is thicker than the side farther away from the bushing.

[0012] By adopting the above technical solution, the side of the support slope closer to the bushing is thicker, giving this area better compressive strength and making it less prone to deformation or damage under large loads. At the same time, this design also optimizes stress distribution, reduces material usage, and achieves lightweight design while ensuring sufficient mechanical properties.

[0013] Optionally, the thickness of the support slope near the bushing is the same as the thickness of the bushing.

[0014] By adopting the above technical solutions, the structural strength and rigidity of this area can be effectively improved, preventing deformation or damage caused by localized stress concentration. At the same time, this design also helps to better disperse the vibrations generated during motor operation, further enhancing the overall stability and reliability of the motor end cover.

[0015] Optionally, the bushing is further provided with a plurality of reinforcing protrusions, which are equidistantly spaced along the bushing, and the reinforcing protrusions and reinforcing ribs do not interfere with each other.

[0016] By adopting the above technical solutions, the reinforcing protrusions on the bushing can effectively improve the structural strength and rigidity of the bushing, prevent deformation or damage during high-speed operation, and ensure that the reinforcing protrusions and reinforcing ribs do not interfere with each other, thus ensuring that their mechanical properties can be performed independently without affecting each other.

[0017] Optionally, each of the reinforcing protrusions and each of the reinforcing ribs are arranged adjacent to each other.

[0018] By adopting the above technical solutions, the adjacent arrangement of the protrusions and reinforcing ribs can effectively improve the overall rigidity and stability of the motor end cover, while avoiding interference between the two, ensuring a compact structure and high strength.

[0019] Optionally, the reinforcing protrusion is arranged in an arc shape and is flush with the bushing.

[0020] By adopting the above technical solutions, the reinforced protrusions, designed in an arc shape, can better disperse stress, improve structural strength and stability, while reducing material usage, further enhancing lightweighting, and reducing the weight of the cover.

[0021] Optionally, a heat dissipation groove is provided on the side of the cover without reinforcing ribs. Multiple heat dissipation grooves are provided, and the heat dissipation grooves are arranged parallel to each other in two directions. The heat dissipation grooves in different directions are perpendicular to each other.

[0022] By adopting the above technical solutions, the heat dissipation performance of the motor end cover can be significantly improved, effectively reducing the heat accumulation generated during motor operation, thereby improving the motor's working efficiency and service life. At the same time, the design of the heat dissipation grooves also helps to reduce the overall weight of the end cover, further achieving lightweight design.

[0023] Optionally, a plurality of reinforcing blocks are provided in the heat dissipation groove, and the reinforcing blocks are fixedly disposed in the heat dissipation groove.

[0024] By adopting the above technical solution, multiple reinforcing blocks are set inside the heat dissipation groove. These reinforcing blocks are fixed inside the heat dissipation groove, which not only further improves the structural strength and prevents deformation or damage caused by long-term use, but also enhances the overall rigidity of the motor end cover.

[0025] In summary, this application has at least the following beneficial effects:

[0026] This application addresses the problem that, in order to better support the rotating shaft, the end cover of the motor is usually reinforced with reinforcing ribs. However, the reinforcing ribs on the motor end cover can easily affect the installation inside the motor, causing interference with the motor's internal components, and increasing the weight of the end cover, making disassembly and assembly inconvenient. This application reduces the length of the reinforcing ribs, which can both strengthen the cover and reduce its weight, thereby improving the ease of end cover installation.

[0033] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] A lightweight motor end cover includes a cover body 1, such as Figure 1 and Figure 2 As shown, a bushing 11 is provided at the center of the cover 1, and the bushing 11 is integrally formed with the cover 1. The bushing 11 is used to install the motor shaft. A connecting plate 2 is provided on the edge of the cover 1, and the connecting plate 2 is arranged circumferentially around the cover 1. The connecting plate 2 has multiple connecting holes 21, which are used to connect with the motor housing. Multiple reinforcing ribs 12 are provided on the side of the cover 1 near the motor housing. The reinforcing ribs 12 are arranged from the bushing 11 toward the connecting plate 2, and an installation space 13 is left between the reinforcing ribs 12 and the connecting plate 2. In specific implementation, both ends of the bushing 11 extend out of the cover 1. The motor shaft passes through the bushing 11 and is rotatably connected to the bushing 11. The motor housing and the cover 1 are connected by bolts at the connecting holes 21 to achieve installation. The installation space 13 is used to make room for the internal components of the motor, reducing the possibility of interference between the internal components of the motor and the reinforcing ribs 12, which would affect the installation and improve the convenience of installation.

[0036] like Figure 1 and Figure 2 As shown, reinforcing ribs 12 are equidistantly spaced along the axial direction of the bushing 11, and each reinforcing rib 12 has the same length. The end of the reinforcing rib 12 near the bushing 11 is fixedly connected to the bushing 11. A supporting inclined surface 121 is provided on the reinforcing rib 12, and the side of the supporting inclined surface 121 near the bushing 11 is thicker than the side away from the bushing 11. The thickness of the side of the supporting inclined surface 121 near the bushing 11 is the same as the thickness of the bushing 11. In specific implementation, the supporting inclined surface 121 enables the reinforcing rib 12 and the bushing 11 to form a triangular support, thereby further improving the support effect on the bushing 11, further improving the strength, and at the same time reducing the material used for the reinforcing rib 12, further reducing the weight of the cover 1, thereby achieving lightweighting.

[0037] like Figure 1 and Figure 2 As shown, the bushing 11 is also provided with a plurality of reinforcing protrusions 111, which are equidistantly spaced along the bushing 11 and do not interfere with each other. Each reinforcing protrusion 111 and each reinforcing rib 12 are arranged adjacent to each other. The reinforcing protrusions 111 are arranged in an arc shape and are flush with the bushing 11. In specific implementation, the reinforcing protrusions 111 can react to the deformation of the bushing 11, which can further reduce the deformation of the bushing 11 due to compression and further improve the strength of the bushing 11.

[0038] Working principle: By reducing the length of the reinforcing rib 12 and setting the slope, the strength of the cover 1 can be maintained, and a certain amount of installation space 13 can be left for easy installation, which further improves the convenience of installing the cover 1.

[0039] Example 2

[0040] like Figure 3 As shown, the main difference between Embodiment 2 and Embodiment 1 is that a heat dissipation groove 14 is provided on the side of the cover 1 without the reinforcing rib 12. Multiple heat dissipation grooves 14 are provided, arranged parallel to each other in two directions, with grooves 14 in different directions perpendicular to each other. Multiple reinforcing blocks 141 are provided within the heat dissipation grooves 14, and the reinforcing blocks 141 are fixedly installed within the heat dissipation grooves 14. In practice, the heat dissipation grooves 14 are interconnected, and the reinforcing blocks 141 do not block the interior of the heat dissipation grooves 14, allowing air to circulate normally within the heat dissipation grooves 14. This not only increases the heat dissipation effect but also further reduces the weight of the cover 1.

[0041] Working principle: The basic working principle is the same as that of Embodiment 1, but this embodiment also has a heat dissipation groove 14, which can not only increase the heat dissipation effect of the cover 1, but also reduce the material used in the cover 1, thereby further realizing the lightweight of the cover 1.

[0042] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
