[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments; the components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0019] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the various embodiments and features described below can be combined with each other.

[0020] Please refer to Figure 1 and Figure 2As shown, this utility model embodiment provides a dual-drive-shaft micro motor, including a motor 100, a transmission structure 200, and an integrally formed dual-head drive shaft 300; the transmission structure 200 is located between the motor 100 and the dual-head drive shaft 300, the output end of the motor 100 is connected to the head end of the transmission structure 200 through a connector 102; the dual-head drive shaft 300 is connected to the tail end of the transmission structure 200 through a connecting assembly.

[0021] It should be noted that the transmission structure 200 is composed of meshing gear sets. Specifically, firstly, the gear sets, through the combination of gears of different sizes, can easily adjust the transmission ratio to achieve deceleration or acceleration, which is crucial in applications requiring specific speeds or torques; secondly, the gear sets can amplify the input torque, especially in situations requiring high torque output; thirdly, the gear sets can change the direction of force, for example, right-angle gears can change the direction of force by 90 degrees, which is particularly important for mechanical designs with limited space; fourthly, gear transmissions are generally highly efficient, especially with proper lubrication and maintenance, with minimal energy loss, reaching 95% or even higher; and fifthly, the gear sets can provide very precise motion control, which is essential for equipment requiring high-precision positioning.

[0022] Furthermore, the transmission structure 200 is relatively simple and easy to maintain. As long as the design is reasonable and the materials are selected appropriately, it can achieve long-term stable operation. Compared with some other transmission methods, gear transmission is cheaper in many cases, especially in mass production and the use of standardized components. At the same time, the gear set can adapt to various working environments and conditions, from high speed and low torque to low speed and high torque, from clean laboratory environments to harsh industrial environments. This utility model optimizes the performance of the mechanical system by setting up a gear set, improves the efficiency and reliability of the dual-drive-shaft micro motor, and can meet specific application requirements.

[0023] In a preferred embodiment, the system further includes a housing 401 and a cover 402; the housing 401 and the cover 402 are connected to form an outer shell cavity 400; the output end of the motor 100 and the transmission structure 200 are located inside the outer shell cavity 400 by being disposed on the cover 402; the head end of the outer shell cavity 400 is connected to the side of the motor 100 near the output end, and the tail end is disposed through the double-headed drive shaft 300; specifically, the transmission structure 200 is disposed on the cover 402 and located inside the outer shell cavity 400, and the outer shell cavity 400 is composed of the housing 401 and the cover 402, which is to facilitate the assembly, disassembly and maintenance of the transmission structure 200, and to ensure that the transmission structure 200 is not damaged.

[0024] Furthermore, the head end of the aforementioned outer shell cavity 400 is connected to the side of the motor 100 near the output end, and the tail end of the outer shell cavity 400 is installed through the dual-head drive shaft 300. This is mainly to ensure the rationality of the structural design of the transmission structure 200, while ensuring the compactness of the transmission structure 200 with the motor 100 and the dual-head drive shaft 300, and improving the service life and efficiency of the dual-drive shaft micro motor.

[0025] As a preferred embodiment, the outer shell cavity 400 is symmetrically provided with at least one set of connection ports 403. Specifically, the symmetrical arrangement of connection ports 403 on the outer shell cavity 400 is mainly to facilitate the stability of the motor 100 installation and connection.

[0027] In a preferred embodiment, the dual-head drive shaft 300 has a step 301 on one side of its head end. Specifically, the step 301 provides a larger contact area, which helps to transmit the torque of the motor 100, improves mechanical stability, and prevents the shaft from twisting or vibrating during high-speed operation. The step 301 structure facilitates the installation of components such as bearings and gears, making assembly and maintenance easier. At the same time, the step 301 can serve as a positioning reference for parts on the shaft, ensuring the correct position of the parts on the shaft. By setting the step 301, the weight of the shaft can be reduced while ensuring strength, thereby reducing the overall weight of the mechanical equipment and improving the stability and reliability of the motor.

[0028] In a preferred embodiment, the motor 100 is provided with a connecting wire 101 on the side away from the output end.

[0029] It should be noted that the dual-drive shaft micro motor provided by this utility model can control the rotation of two shafts simultaneously, enabling more precise positioning and coordinated movement, meeting the high power requirements of automation, and allowing for flexible switching between high and low speeds to adapt to different working conditions; it achieves consistency in torque, speed, precision, and control of the dual-drive shaft 300 of the motor 100, thereby improving production efficiency.

The bearing structure 500 operates with its dual-head drive shaft 300 running through the bearing structure 500 and gear 501, symmetrically positioned on both sides of the bearing structure 500. Primarily, its motor 100 drives the gear set of the transmission structure 200 to rotate, which in turn drives gear 501 to rotate the bearing structure 500, which in turn drives the dual-head drive shaft 300 to rotate. The dual-head drive shaft 300 is connected to the target equipment, and the motor 100, through the transmission structure 200, drives both the dual-head drive shaft 300 and the target equipment to rotate. This achieves consistency in torque, speed, precision, and control between the motor 100 and the dual-head drive shaft 300, improving production efficiency.
