Description

Technical Field

[0001] This utility model relates to the field of micro motor technology, specifically to a wear-resistant micro motor gear plate. Background Technology

[0002] Micro motors, typically referring to miniaturized and precision electric motors with a diameter less than 160mm or an output power less than several hundred watts, are widely used in automotive electrical systems, smart homes, consumer electronics, medical devices, robotics, and precision instruments. In these applications, micro motors often require gear transmission systems to achieve functions such as speed reduction, torque increase, or alteration of motion. The gear plate, as a key fundamental component supporting and fixing multiple gear shafts in a gear transmission system, directly determines the accuracy, efficiency, noise level, and service life of the entire transmission system.

[0003] The Chinese utility model patent with authorization announcement number "CN222596697U" is specifically "a wear-resistant micro motor gear plate". Through the setting of the protective layer, the wear-resistant layer can greatly improve the wear resistance of the gear plate, reduce the wear of the gear plate, and increase the service life of the gear plate. The insulating layer can give the mounting plate good insulation, ensuring the safe use of the motor while effectively avoiding possible electrochemical corrosion of the gear plate, further improving the service life of the motor.

[0004] The aforementioned device improves the wear resistance of the gear plate by applying a wear-resistant coating to the outside of the gear plate. Although the wear-resistant coating can improve the wear resistance of the gear plate, the coating process is complex, which increases the number of steps in the production of the gear plate and affects the production efficiency of the gear plate. In addition, the gear plate does not have a reinforcing structure, so its overall strength is weak and it is prone to wear. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wear-resistant micro motor gear plate, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a wear-resistant micro motor gear plate, comprising: The plate body has a connector in the middle, and arc-shaped grooves with equal spacing are opened on the outer side of the plate body. The plate body also has insertion holes with equal spacing on the outer side of the plate body. The fixing component includes two fixing feet that are symmetrically fixedly connected to the outside of the plate body, and the fixing feet have mounting holes at the bends; The reinforcing component includes an outer ring fixedly connected to the outside of the plate body, and an inner ring fixedly connected to the outside of the plate body.

[0007] Preferably, the plate body has a connecting hole at its center, and the connector is installed on the inner wall of the connecting hole.

[0008] Preferably, the edge of the plate body is provided with an arc-shaped surface.

[0009] Preferably, a rubber ring is fixedly connected to the outer side of the plate body.

[0010] Preferably, four sets of connecting rods arranged in a fan shape are fixedly connected to the outer side of the inner ring, and the end of the connecting rod away from the inner ring is fixedly connected to the inner wall of the outer ring.

[0011] Preferably, the inner wall of the inner ring is fixedly connected with scattering strips, which are densely distributed at equal intervals on the inner wall of the inner ring.

[0012] Preferably, the main body of the plate, the outer ring, the inner ring, the connecting rod, and the scattering strip are all made of polyoxymethylene and manufactured through a one-time molding process.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model improves the overall and local rigidity of the gear plate by setting up a reinforcing component, including an inner ring and an outer ring on the outer side of the plate body, with a connecting rod between the inner and outer rings. This suppresses the deformation of the bearing hole under stress, maintains the correct center distance and meshing position of the gear shaft, ensures smooth and uniform transmission of the gear pair, avoids uneven loading and impact, and ultimately achieves long-term wear resistance of the bearing hole and gear tooth surface. Furthermore, it is integrally formed with the plate body, with a simple process and good production efficiency.

[0014] 2. This utility model, by setting a fixing component, can stably fix the plate body to the motor housing during installation. Furthermore, the curved surface and rubber ring ensure that the outer surface of the plate body fits snugly against the inner wall of the motor housing, thus preventing shaking during operation and reducing wear on the gear plate during micro-motor operation.

[0017] 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 only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figure 1-4 The first embodiment of this utility model discloses a wear-resistant micro-motor gear plate, comprising: The plate body 1 has a connector 2 in the middle and a connecting hole 10 in the center. The connector 2 is installed on the inner wall of the connecting hole 10. The connector 2 is the key foundation for the installation and rotation of the gear shaft. The outer side of the plate body 1 has arc-shaped grooves 3 and insertion holes 4 with equal spacing. These arc-shaped grooves 3 and insertion holes 4 not only help to effectively reduce the overall weight of the gear plate while ensuring structural strength, but more importantly, they provide an effective flow channel for the heat generated during the operation of the micro motor, promote the heat dissipation of the gear plate, and avoid the material performance degradation or deformation due to excessive temperature rise.

[0020] The reinforcing component includes an outer ring 9 fixedly connected to the outside of the plate body 1. The outer ring 9 forms a reinforcing frame for the outer edge of the gear plate. An inner ring 12 is fixedly connected to the outside of the plate body 1 as a local reinforcing structure for the bearing mounting area.

[0021] Specifically, four sets of fan-shaped connecting rods 11 are fixedly connected to the outer side of the inner ring 12. Each set of connecting rods 11 has two rods. The two connecting rods 11 work together with the inner ring 12 and the outer ring 9 to form a fan shape. The connecting rods 11 establish a stable force transmission path between the inner ring 12 and the outer ring 9. The end of the connecting rod 11 away from the inner ring 12 is fixedly connected to the inner wall of the outer ring 9.

[0022] This design allows the load transmitted from the gear shaft to the inner ring 12 and the center of the plate body 1 to be effectively distributed and transmitted to a wider area of ​​the outer ring 9 and the plate body 1 through multiple connecting rods 11, significantly improving the overall and local rigidity of the gear plate. The direct effect of this reinforcement is that it effectively suppresses the deformation of the bearing bore under stress, especially radial and meshing forces, thereby ensuring that the gear shaft always maintains the correct center distance and meshing position. This lays the foundation for smooth and uniform transmission of the gear pair, avoiding uneven loading and impact caused by changes in center distance, and ultimately significantly extending the service life of the bearing bore and gear tooth surface, achieving long-term wear resistance.

[0023] Specifically, a scattering strip 13 is fixedly connected to the inner wall of the inner ring 12. The scattering strip 13 is densely distributed at equal intervals on the inner wall of the inner ring 12 to increase the strength at the connection hole 10.

[0024] Specifically, the main body 1, outer ring 9, inner ring 12, connecting rod 11 and scattering strip 13 are all made of polyoxymethylene and manufactured through a one-time molding process.

[0025] Polyoxymethylene (POM) has excellent mechanical strength, wear resistance, and dimensional stability. Moreover, this one-piece molding manufacturing method avoids subsequent assembly or connection processes, which not only simplifies the production process and improves production efficiency, but more importantly, ensures that the reinforcing components and the main body of the plate form a seamless integral structure, eliminating potential weak points in the connection and further guaranteeing the structural integrity and reliability of the gear plate.

[0026] Example 2: Reference Figure 1-3 This is the second embodiment of the present invention, which differs from the first embodiment in that: The fixing component includes two fixing feet 7 that are symmetrically fixed to the outside of the plate body 1. The design of these two fixing feet 7 provides a balanced fixing point. The fixing feet 7 have mounting holes 8 at the bends for fasteners such as bolts to pass through, thereby firmly locking the gear plate to the predetermined mounting position on the motor housing.

[0027] Specifically, the edge of the main body 1 is provided with an arc-shaped surface 6, and a rubber ring 5 is fixedly connected to the outside of the main body 1.

[0028] As the fasteners are tightened, the arc-shaped surface 6 at the edge of the main body 1 guides the gear plate to ensure that its rubber ring 5 fits tightly against and is compressed against the inner wall of the motor housing. The rubber ring 5 plays a dual role in this process: firstly, by utilizing the deformation of its elastic material, it compensates for manufacturing tolerances and assembly gaps, ensuring that the gear plate remains secure within the housing; secondly, the rubber ring 5 has excellent damping characteristics, absorbing and isolating vibrations generated during micro-motor operation, effectively preventing accelerated wear and noise generation on the gear plate due to high-frequency micro-vibrations.

[0029] The remaining structure is the same as that in Example 1.

[0030] The workflow of this utility model is as follows: When installing the gear plate, align the end of the plate body 1 with the arc-shaped surface 6 with the inside of the micro motor housing and insert it until the fixing foot 7 reaches the installation position. At this time, the fixing foot 7 and the micro motor housing can be connected by bolts to complete the installation of the plate body 1. After installation, the rubber ring 5 on the outside of the plate body 1 is in close contact with the inner wall of the micro motor housing. When the plate body 1 is in use, the inner ring 12, outer ring 9, connecting strip and radial strip form a grid that is evenly distributed on the outside of the plate body 1, which effectively disperses and transmits the force on the bearing hole to a larger area and edge of the gear plate. The connecting piece 2 maintains its original shape and size when under force, and the shaft rotates stably in it, thereby reducing the wear of the gear plate. When the micro motor is working, the heat generated can flow through the unused plug hole 4 and the arc groove 3, thereby reducing the weight of the main body 1 and facilitating heat dissipation.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
