[0002] A geared motor is a power transmission device that converts the high speed and low torque of an electric motor into low speed and high torque. With the development of industrial automation, machinery manufacturing, and precision control, the technical requirements for geared motors are becoming increasingly stringent.

[0003] The working principle of a geared motor is mainly to reduce speed and increase torque through gears, worm gears, or other transmission mechanisms. The motor input shaft transmits high-speed, low-torque power to the output shaft through the transmission mechanism, and the output shaft outputs higher torque at a lower speed. Different types of geared motors will have different transmission mechanisms and transmission ratios.

[0004] The geared motor must meet the following main technical requirements:

[0005] 1. High transmission efficiency: While ensuring output torque, it minimizes energy loss and improves overall transmission efficiency.

[0006] 2. Compact structure: While meeting performance requirements, the structural design is optimized to reduce volume and weight, making it easy to install and operate.

[0007] 3. Smooth operation: Reduce vibration and noise to ensure smooth and reliable equipment operation.

[0008] 4. Long service life: High-quality materials and advanced manufacturing processes are used to improve product life and maintenance cycle.

[0009] To further meet the requirement of a compact structure, this application provides a geared motor assembly. This assembly connects the front end of the geared motor to the gearbox housing of the gearbox via a composite motor front cover. Compared to conventional geared motor structures, this structure eliminates the need for a mounting bushing between the gearbox housing and the geared motor. Eliminating the bushing further reduces the length of the drive shaft and also lowers the load on the extended drive shaft. The composite electrode front cover of this application adopts a double-layer contact end face structure, which can simultaneously mate with both the motor end and the gearbox housing, placing the worm gear components inside the gearbox housing and reducing the probability of internal structure contact with the external environment. The double-layer end face composite electrode front cover structure can be machined into a single piece, resulting in a simplified structure and high strength. Summary of the Invention

[0012] Furthermore, the motor front cover has a double-sided cover structure, and the motor front cover includes a rear cover layer and a front cover layer;

[0013] The rear cover has a lower shaft hole at its center, and a motor docking end extends integrally from the outer ring of the rear cover along the lower shaft hole. The circular plate structure of the motor docking end matches and docks with the front end of the motor.

[0014] Furthermore, the front cover layer has an irregular rectangular structure, with a lower shaft hole at the center and an upper shaft hole at the top of the lower shaft hole.

[0015] Furthermore, the upper shaft hole has an integrally extended reinforcing rib at its edge, and both the upper and lower shaft holes are retained in the groove at the center of the front cover layer. The front cover layer has six sets of mounting holes distributed along its raised end face.

[0016] Furthermore, a bearing housing is integrally connected to the inside of the reducer housing, the bearing housing has a key shaft hole in the center, and a turbine cover is connected to the top of the bearing housing.

[0017] Furthermore, a vent cap is installed on the top of the reducer housing.

[0018] Furthermore, the gearbox housing retains machined edges and corners, and mounting through holes are provided on the plane of the machined edges and corners.

[0019] The beneficial effects of this utility model are as follows:

[0020] Compared with existing technologies, this application provides a geared motor assembly. This assembly connects the front end of the geared motor to the gearbox housing of the gearbox via a composite motor front cover to complete the installation process. Compared with conventional geared motor structures, this structure eliminates the installation connecting bushing between the gearbox housing and the geared motor. Eliminating the bushing further reduces the length of the drive shaft and also reduces the load after the drive shaft is extended.

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a geared motor assembly includes a motor and a fan cover. A fan cover 1 is installed at the fan position of the rear end of the motor 11. A terminal box 7 is bolted to the side of the motor 11. A motor front cover 6 is installed at the front end of the motor 11, and the front end face of the motor front cover 6 is connected to the gearbox housing 4. The fan cover 1 at the rear of the motor 11 prevents impurities from entering the motor fan and its interior. The design of the motor front cover 6 is a unique structure of this application. This structure abandons the original shaft sleeve structure of the geared motor, combining the front cover with the shaft sleeve, ultimately appearing as the motor front cover 6 and cooperating to connect the motor body to the gearbox housing 4. Compared with the conventional geared motor structure, this structure eliminates the installation connection shaft sleeve between the gearbox housing and the geared motor. The elimination of the bushing in the geared motor can further reduce the length of the drive shaft, and at the same time reduce the load after the drive shaft is extended; the composite structure electrode front cover of this application adopts a double-layer contact end face structure, which can be connected with the motor end and the gearbox housing at the same time, and the worm gear accessories are placed inside the gearbox housing, reducing the probability of internal structure contact with the outside.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the motor front cover 6 has a double-sided cover structure, and the motor front cover 6 includes a rear cover layer 6-1 and a front cover layer 6-2;

[0031] The rear cover 6-1 has a lower shaft hole 9 at its center. A motor docking end 10 extends integrally from the outer ring of the rear cover 6-1 along the lower shaft hole 9. The circular plate structure of the motor docking end 10 matches and docks with the front end of the motor. The lower shaft hole 9 serves as a guide hole for the drive shaft of the motor 11. To facilitate the installation of the motor 11, the central structure of the rear cover 6-1 is made into a circular plate structure.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the front cover 6-2 has an irregular rectangular structure. A lower shaft hole 9 is located at the center of the front cover 6-2, and an upper shaft hole 8 is formed at the top of the lower shaft hole 9. The lower shaft hole 9 serves as a guide hole for the worm gear transmission shaft of the geared motor. This double-hole design of the cover structure further saves space in the equipment, achieving reduced load and increased efficiency.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a reinforcing rib extends integrally from the edge of the upper shaft hole 8. Both the upper shaft hole 8 and the lower shaft hole 9 are located within the groove at the center of the front cover layer 6-2. The front cover layer 6-2 has six sets of mounting holes distributed along its raised end face. The design of these six sets of mounting holes allows for installation with the reducer housing 11. The mirrored distribution of these six sets of mounting holes improves the installation stability of the reducer housing 11. The reinforcing rib design enhances the structural strength of the dual shaft holes.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a bearing housing 5 is integrally connected to the inner side of the reducer housing 4. A key shaft hole 5-1 is retained in the center of the bearing housing 5, and a turbine cover 2 is connected to the top of the bearing housing 5.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vent cap 3 is installed on the top of the reducer housing 4.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the four corners of the reducer housing have machined corners 4-1, and mounting through holes are provided on the plane of the machined corners 4-1. The machined corners 4-1 can be prefabricated, allowing for later processing such as adding plane openings and addressing plane wear as needed.

[0037] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
