Description

Technical Field

[0001] The utility model belongs to the field of motor equipment, and in particular relates to a heat-conducting cast iron with a quick installation structure. Background Art

[0002] Thermally conductive cast iron used in motor windings is a special cast iron material specifically designed to dissipate heat from the motor windings. However, in practice, this material presents several challenges. First, installation is time-consuming and complex due to the need for specialized tools and precise handling. This is due to the lack of specially designed, convenient installation components. This can lead to excessive installation time, as manual operation is subject to subjective factors, potentially resulting in discrepancies between the cast iron, the motor windings, and the housing. Conventional solutions to address these installation challenges include enhanced personnel training and additional inspection steps. This increased training increases labor costs and time, and its effectiveness is hampered by the personnel's competence. Adding inspection steps also prolongs production cycles and reduces efficiency. Furthermore, the lack of a quick-installation mechanism makes disassembly and reassembly difficult during maintenance, extending repair time and impacting equipment efficiency. Therefore, a new structure is needed to address these technical issues. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a heat-conducting cast iron with a quick installation structure, comprising: a motor assembly and a cast iron assembly 200, wherein the cast iron assembly 200 for heat conduction is installed inside the motor assembly, the motor assembly comprises: a motor housing 100, a front end cover 130130 and a rear end cover 140, the interior of the motor housing 100 is provided with a accommodating cavity, the front side surface and the rear side surface of the motor housing 100 are respectively designed to be open, a sealing cover 120 is respectively installed at the opening of the front side surface and the rear side surface of the motor housing 100, the front side surface and the rear side surface of the motor housing 100 are respectively installed with the front end cover 130130 and the rear end cover 140 through the sealing cover 120, the cast iron assembly 200 comprises: a cast iron ring 220, a motor winding package 210 and a mounting piece, the motor winding package 210 is installed inside the cast iron ring 220, and the outer surface of the cast iron ring 220 is installed with a mounting piece, four groups of mounting pieces are provided, and the four groups of mounting pieces have the same structure.

[0022] See also Figures 1 to 5 As a first embodiment of the present invention: a plurality of heat dissipation fins 101 are uniformly and integrally formed on the outer surface of the motor housing 100. The material of the motor housing 100 matches that of the cast iron ring 220. A heat dissipation hole 110 is opened at the center of the upper side of the outer surface of the motor housing 100. A sealing cover 120 of the same structure is fixed to the front and rear surfaces of the motor housing 100 by screws respectively.

[0023] A sealing ring is provided at the abutment between the sealing cover 120 and the motor housing 100. A motor winding package 210 is installed inside the accommodating cavity of the motor housing 100 through a mounting piece and a cast iron ring 220. The motor winding package 210 is a stator motor winding package 210. A rear shell cover 150 is installed on the rear surface of the rear end cover 140 of the motor housing 100.

[0024] When in use, the user first installs the internal components of the motor housing 100, and installs the motor parts such as the motor winding 210 inside the motor housing 100 (the specific installation position and specific installation structure are not repeated here). After the motor parts of the motor housing 100 are installed, the sealing cover 120 is installed on the front and rear sides of the motor housing 100 respectively. After the sealing cover 120 is installed, the front cover 130130, the rear cover 140 and the rear shell cover 150 can be installed. At this time, the motor is installed. Because cast iron has good thermal conductivity during use, it can quickly conduct away the heat generated during the operation of the motor. When the motor is working, especially when it is under high load, it will generate a lot of heat. If it cannot be dissipated in time, the motor temperature will be too high, affecting the performance and life of the motor. The cast iron ring 220, as a heat-conducting component, can effectively reduce the temperature of the motor winding 210, so that it can work within a more suitable temperature range, thereby ensuring the normal operation of the motor and improving the reliability and stability of the motor.

[0025] See also Figures 1 to 5 As a second embodiment of the present invention: a cast iron ring 220 is mounted on the outer surface of the motor winding 210, and the mounting parts include: a curved plate 230, a movable column 240, and a compression spring 241. Four curved plates 230 are mounted on the outer surface of the cast iron ring 220 via the movable column 240. The four curved plates 230 form a circular structure. The curvature of the side surface of the curved plate 230 away from the movable column 240 matches the curvature of the inner surface of the motor housing 100.

[0026] The end of the movable column 240 away from the arc plate 230 is movably arranged inside the cast iron ring 220. The outer surface of the movable column 240 is provided with a compression spring 241. The two ends of the compression spring 241 are respectively connected to the inner surface of the arc plate 230 and the outer surface of the cast iron ring 220.

[0027] The cast iron ring 220 is fixed inside the motor housing 100 by being squeezed by the movable column 240, the arc plate 230 and the compression spring 241;

[0028] During use, when installing the cast iron component 200 (the cast iron component 200 is installed on the outer surface of the motor winding package 210. As for how to install the motor winding package 210 and the cast iron component 200, it needs to be selected according to actual conditions and will not be elaborated here), when the cast iron component 200 and the motor winding package 210 are installed inside the motor housing 100, first, the outer surface of the arc plate 230 on the outer surface of the cast iron ring 220 is abutted against the inner wall of the motor housing 100. When the four arc plates 230 are abutted against the inner wall of the motor housing 100 through the above steps, the movable column 240 on the inner surface of the arc plate 230 will gradually extend into the cast iron ring 220 because the inner wall of the motor housing 100 squeezes the arc plate 230. At this time, the extrusion spring on the outer surface of the movable column 240 will also be squeezed, providing a reverse rebound force for the arc plate 230, so that the outer surface of the arc plate 230 abuts against the inner wall of the motor housing 100, thereby The cast iron ring 220 is fixed inside the motor housing 100 through the mounting parts. During actual use, the minimum diameter of the motor housing 100 shall not be less than the minimum diameter of the four curved plates 230 after retraction. At the same time, when the motor winding 210 generates temperature, it will be transferred to the cast iron ring 220, causing the cast iron ring 220 to heat up. At this time, an annular accommodating cavity is provided between the curved plate 230 and the cast iron ring 220. Since the heat dissipation hole 110 is in contact with the curved plate 230, the curved plate 230 dissipates heat through the heat dissipation fins 101 and the heat dissipation holes 110 on the surface of the motor housing 100. Due to the presence of the mounting parts, the purpose of rapid installation can be achieved during the production and manufacturing process of the motor. The rapid installation structure can significantly shorten the assembly time of a single motor. Compared with the traditional complex installation method, workers can more quickly install the motor winding 210 into the motor housing 100 with the mounting parts, thereby speeding up the speed of the entire production process.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
