Description

Technical Field

[0001] The utility model relates to the technical field of motor equipment, in particular to an internally ventilated motor base. Background Art

[0002] With the rapid development of modern industrial technology, motors, as the core power components in mechanical equipment, have attracted much attention for their operating efficiency and reliability. However, motors generate a lot of heat during operation. If they cannot be dissipated in a timely and effective manner, it will seriously affect the working performance of the motor, shorten its service life, and may even cause safety problems. Traditional motor frame designs often focus on the support and fixation of the motor, and the degree of satisfaction of heat dissipation requirements is limited, especially in high power density and compact motor designs, where heat dissipation issues become more and more prominent.

[0003] At present, the motor base on the market generally adopts the method of covering the outside of the base with an outer cover to form a ventilation duct to dissipate heat, but this design has low heat dissipation efficiency and is difficult to meet the high standard requirements of high-performance motors for heat dissipation. In addition, this structure usually means that two sets of independent molds need to be developed for production, which not only has low processing efficiency, but also increases the cost investment in mold development and production.

[0027] The first accommodating space 100 is helpful for the assembly and positioning of the stator, reducing the vibration and noise during the rotation of the motor, thereby improving the performance of the motor; the screw platform 130 arranged on the outer wall of the cylinder 110 is conducive to fixing the motor, ensuring that the motor can be reliably fixed on the cylinder 110, thereby enhancing the overall stability of the motor; the ventilation duct 150 between the cylinder 110 and the outer shell 120 can promote the circulation of air flow, and help to quickly discharge the heat generated during the operation of the motor; the cylinder 110 and the outer shell 120 are connected by the connecting part 140, which can improve the strength and rigidity of the overall structure of the outer shell 120 and the cylinder 110, thereby enhancing the stability of the overall structure of the motor.

[0028] In this embodiment, the first accommodation space 100 formed inside the cylinder 110 has an inner diameter that precisely matches the outer diameter of the motor stator, ensuring the stable installation of the stator. Four screw platforms 130 are provided on the outer wall of the cylinder 110, and these screw platforms 130 are arranged at equal intervals along the circumference of the stator, with the purpose of firmly fixing the motor on the cylinder 110 by screws. At the same time, the outer wall of the cylinder 110 is also provided with four connecting parts 140, which are arranged at intervals along the circumference of the cylinder 110 for effective connection with the shell 120. The shell 120 is designed as a square structure, and all corners are connected by arc transition structures to enhance structural strength and reduce stress concentration, while also enhancing the overall appearance of the craftsmanship aesthetics. The second accommodation space is formed in the center of the shell 120, and the cylinder 110 is connected to the shell 120 respectively through four connecting parts 140, and a reasonable ventilation duct 150 is formed between the two to ensure efficient heat dissipation when the motor is running. The screw platform 130 and the cylinder 110 are connected by an arc transition structure, which avoids stress concentration, significantly enhances the mechanical strength and fatigue resistance of the connection part 140, and ensures that the entire motor base can maintain good stability under various working conditions. The internal ventilation motor base of this embodiment is not only compact in structure and efficient in heat dissipation, but also has cost-effectiveness and advanced technology in production and manufacturing, and is suitable for the installation and use of various motor equipment.

[0029] There are four connecting parts 140, and the four connecting parts 140 divide the air inlet passage formed around the cylinder 110 into four parts. After the air inlet passage is divided into four areas, the airflow entering the motor can be more evenly guided and distributed, the heat dissipation efficiency is improved, and local overheating is avoided.

[0030] There are four screw platforms 130, which are arranged at intervals along the outer wall of the cylinder 110, and are respectively arranged in four ventilation ducts 150 divided by four connecting parts 140. Providing multiple screw platforms 130 can balance the force, facilitate the positioning of the motor, and improve the efficiency of installation.

[0031] The cylinder 110 is also provided with reinforcing ribs 160, which are arranged at intervals along the circumference of the cylinder 110, one end of the reinforcing rib 160 is connected to the screw platform 130, and the other end is connected to the housing 120, and the connecting portion 140 and the screw platform 130 divide the air inlet channel into eight equal parts. The reinforcing ribs 160 can further improve the overall structural strength and rigidity of the cylinder 110, divide the air inlet channel into eight equal parts, so that the airflow can be more evenly distributed and flowed inside the motor, thereby significantly improving the heat dissipation efficiency of the motor.

[0032] The column heat sink is arranged inside the reinforcing rib 160. The reinforcing rib 160 can also be used as a heat sink. This design not only saves space and improves the compactness of the structure, but also realizes the organic combination of heat dissipation function and support function without affecting the overall structural strength, effectively reduces the weight of the motor base, and improves the overall performance.

[0033] There are four reinforcing ribs 160. Providing a plurality of reinforcing ribs 160 can strengthen the overall structure, and effectively improve the bending, torsion and shear resistance of the cylinder 110 while ensuring the lightweight structure.

[0035] The wall thickness of the cylinder 110 is A, which satisfies 2.5 mm ≤ A ≤ 6 mm. To ensure that the cylinder 110 has sufficient mechanical strength, the width of the ventilation duct 150 between the cylinder 110 and the housing 120 can be expanded, thereby further improving the heat dissipation performance.

[0036] A circular arc transition structure is provided between the screw platform 130 and the cylinder body 110 to avoid stress concentration and enhance the mechanical strength and fatigue resistance of the connection part 140 .

[0037] The cylinder 110 and the shell 120 adopt an integrated casting or extrusion molding process, and the entire internal ventilation motor base only needs to use one set of molds to successfully complete the production process, which significantly simplifies the production steps and reduces the mold cost and manufacturing cycle. It is understandable that the original design requires two sets of molds, one for producing the shell 120 and the cylinder 110, respectively, while the present solution uses one set of molds to complete the production, achieving efficient and economical production. The internal ventilation motor base can be made by the lost foam cast iron process or the extrusion process of high-strength alloy aluminum, both of which can ensure the stability of the base structure and excellent mechanical properties. According to actual needs, the length of the base can be flexibly customized or cut and adjusted according to specific circumstances. In the design of the internal circumferential size of the cylinder 110, an appropriate processing allowance is reserved, which can not only ensure that the subsequent finishing process can be carried out smoothly, but also consider the use of extrusion finishing process to achieve the purpose of free processing or less processing, which not only saves materials and working hours, but also further improves production efficiency and product precision level.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
