Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, and in particular to a waterproof servo motor structure. Background Technology

[0002] Servo motors are drive devices that can precisely control speed, position, and torque. They are widely used in automated production lines, robots, precision instruments, and other fields. Their core function is to convert electrical signals into mechanical motion, enabling high-precision control of mechanical systems. They are key components that ensure the stable operation of automated equipment.

[0003] Existing waterproof servo motors possess excellent waterproof performance and can operate stably in humid or water-rich environments. Structurally, the outer casing is a sealed metal shell with rubber sealing rings at the seams; a skeleton oil seal is installed between the output shaft and the end cover to prevent moisture intrusion; the stator windings are coated with waterproof insulating varnish, and components such as the encoder are sealed; some products have also passed IP67 waterproof rating certification, allowing for short-term immersion in water.

[0004] However, while the existing waterproof servo motor sealing structure improves waterproofing, it hinders the dissipation of internal heat. During operation, the performance is easily affected by excessive temperature. Under long-term high-load operation, heat accumulation can easily lead to insulation aging. Therefore, a waterproof servo motor structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a waterproof servo motor structure, which aims to improve the problem of difficult heat dissipation inside the motor in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A waterproof servo motor structure includes a first housing and a second housing. A front cover and a rear cover are respectively installed at both ends of the first housing. Sealing components are installed inside the front cover and the rear cover. A heat dissipation component is installed inside the first housing. A motor body is installed inside the second housing. An output rod is installed at one end of the motor body. The heat dissipation assembly includes a fan, which is fixedly connected to the outside of the output rod. Spiral fins are fixedly connected to the outside of the second outer casing. An air intake pipe is fixedly connected to the outside of the front cover, and an exhaust pipe is fixedly connected to the outside of the rear cover. As a further description of the above technical solution: The sealing assembly includes two retaining rings, which are respectively fixedly connected to the inner walls of the front cover and the rear cover. Both ends of the outer shell are provided with mounting grooves. A sealing ring is installed inside the mounting groove. A sealing groove is provided inside the sealing ring.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the fan, air intake pipe and exhaust pipe work together to draw outside air into the device and form a directional airflow for discharge. The air is then blown out through the spiral fins. On the one hand, the fin structure greatly increases the contact area between the outer shell and the air, making heat exchange more efficient. On the other hand, the spiral layout can guide the airflow along a preset path, allowing the air to quickly and evenly cover the entire surface of the outer shell, avoiding the occurrence of local heat dissipation dead zones, thereby significantly improving heat dissipation efficiency.

[0008] 2. In this utility model, the design of the sealing ring has significant advantages. It can effectively fill the gap between the outer shell and the retaining ring, thereby increasing the actual contact area between the two and greatly improving the sealing performance of the contact surface. It effectively prevents dust, water vapor and other substances from entering through the gap. In addition, the equipment adopts a double-layer structure design that combines the outer shell and the second outer shell.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1-3 The present invention provides an embodiment of a waterproof servo motor structure, comprising a first outer shell 1 and a second outer shell 16. The first outer shell 1 serves as the outer protective structure of the motor, while the second outer shell 16 primarily provides direct protection for the internal motor body 17. The two together constitute a dual protection system for the motor. A front cover 4 and a rear cover 5 are respectively installed at both ends of the first outer shell 1. The front cover 4 and the rear cover 5 are precisely connected to the ends of the first outer shell 1, forming a closed space for the motor. Sealing components are installed inside the front cover 4 and the rear cover 5. A heat dissipation component is installed inside the first outer shell 1. The heat dissipation component can dissipate the heat generated during motor operation in a timely manner, ensuring stable operation of the motor. The motor body 17 is installed inside the second outer shell 16. The motor body 17 is the core power component of the entire motor. An output rod 18 is installed at one end of the motor body 17. The heat dissipation assembly includes a fan 22, which is fixedly connected to the outside of the output rod 18. When the output rod 18 rotates, it can synchronously drive the fan 22 to run without the need for an additional drive device. Spiral fins 21 are fixedly connected to the outside of the outer shell 16. The spiral fins 21 are evenly distributed in a spiral shape on the outside of the outer shell 16. An air intake pipe 6 is fixedly connected to the outside of the front cover 4. The air intake pipe 6 is the channel for outside air to enter the motor. An exhaust pipe 7 is fixedly connected to the outside of the rear cover 5. The exhaust pipe 7 is used to exhaust the hot air that has completed heat exchange inside the motor. The positions of the air intake pipe 6 and the exhaust pipe 7 are reasonably distributed to ensure smooth airflow inside the motor. A dustproof net 23 is installed inside the outer shell 1. The mesh of the dustproof net 23 is fine and can effectively block dust and other impurities in the air. The dustproof net 23 is located between the fan 22 and the outer shell 16.

[0013] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The sealing assembly includes two retaining rings 12, which are fixedly connected to the inner walls of the front cover 4 and the rear cover 5, respectively. The retaining rings 12 are firmly connected to the inner walls of the front cover 4 and the rear cover 5, and can be installed together with the front cover 4 and the rear cover 5. Both ends of the outer casing 1 have mounting grooves 15, the dimensions of which match the sealing ring 13, providing a stable installation position for the sealing ring 13. The sealing ring 13 is installed inside the mounting groove 15. The sealing ring 13 is made of a highly elastic sealing material, and a sealing groove 14 is formed inside the sealing ring 13. The shape and size of the sealing groove 14 match the retaining ring 12. The retaining ring 12 is snapped into the inside of the sealing groove 14. Through the tight snapping of the retaining ring 12 and the sealing groove 14, the sealing ring 13 can fully exert its sealing function. The outer sides of the front cover 4 and the rear cover 5 are fixedly connected with flange ring 1, and the two ends of the outer shell 1 are fixedly connected with flange ring 2. The flange ring 1 is an integral structure with the front cover 4 and the rear cover 5 or is fixed by a strong connection method. The internal threads of flange ring 1 and flange ring 2 are connected with multiple bolts 10. By tightening these bolts 10, the front cover 4, the rear cover 5 and the outer shell 1 can be tightly fixed together, further enhancing the sealing performance and stability of the connection.

[0014] Reference Figure 1 , Figure 2 and Figure 4A waterproof bearing 11 is fixedly connected to the middle of the output rod 18. The outer side of the waterproof bearing 11 is fixedly connected to the inside of the front cover 4. The waterproof bearing 11 has good waterproof performance and can prevent water from entering through the connection between the output rod 18 and the front cover 4. A sealing bearing 19 is fixedly connected to one end of the output rod 18. The sealing bearing 19 can further enhance the sealing of the connection between the output rod 18 and the outer shell 16. The outer side of the sealing bearing 19 is fixedly connected to the inside of the outer shell 16. Two fixing brackets 20 are installed inside the outer shell 16. The motor body 17 is located inside the fixing brackets 20. The fixing brackets 20 play a firm role in fixing the motor body 17, which can reduce the displacement of the motor body 17 due to vibration during operation and ensure the stability of motor operation. A bracket 2 is fixedly connected to the bottom of the outer shell 1. The bottom of the bracket 2 has multiple mounting holes 3. The multiple mounting holes 3 facilitate the installation of the motor in the required working position by bolts and other connecting parts to meet the installation needs of different scenarios.

[0015] Working principle: First, when the motor body 17 starts working, it drives the output rod 18 to rotate, and the output rod 18 in turn drives the fan 22 to rotate. The fan 22 draws in outside air through the air intake pipe 6 and exhausts it. After passing through the holes of the dust filter 23, the air is blown onto the surface of the outer shell 16. The spiral fins 21 enable the air to blow quickly and evenly across the surface of the outer shell 16, which increases the heat dissipation area and improves the heat dissipation efficiency. Finally, the hot air after exchanging temperature with the air is discharged from the exhaust pipe 7, realizing active heat dissipation and saving energy.

[0016] Secondly, when installing the front cover 4, first install the sealing ring 13, then snap the retaining ring 12 into the sealing groove 14, and finally tighten the bolt 10 to complete the installation. The design of the sealing ring 13 can effectively increase the contact area between the outer shell 1 and the retaining ring 12, making the sealing performance better, and the installation process is simple and quick. In addition, the double-layer structure of the outer shell 1 and the outer shell 2 16 is more conducive to waterproofing and can prevent water from entering the interior.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
