[0017] 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.

[0018] Please see Figure 1-2 This utility model provides a technical solution: a permanent magnet DC motor structure for a barbecue grill gearbox, including a gearbox body 1, an installation stop on the right side of the gearbox body 1, an oil-impregnated bearing 2 inside the gearbox body 1, a gear transmission component 3 inside the gearbox body 1, a fixed bracket 4 on the right side of the gear transmission component 3, a gearbox cover 5 on the right side of the fixed bracket 4, a motor 6 on the right side of the gearbox cover 5, and a rear cover 7 on the right side of the motor 6.

[0019] The gearbox housing 1 is made of one piece of cast aluminum, which improves the structural strength of the gearbox housing 1. Then, the gearbox cover 5 is made of sheet metal stamping, which effectively reduces the processing cost of the gearbox cover 5. Finally, the fixed bracket 4 is made of injection molding, which makes the fixed bracket 4 have high structural strength and good stability, effectively preventing the gear transmission component 3 from axial movement, and effectively improving the overall practicality of the device.

[0020] In order to improve the structural strength of the gearbox housing 1, this utility model adopts a one-piece cast aluminum molding method for the gearbox housing 1. The structure made by the one-piece cast aluminum molding method has higher structural strength, thus improving the structural strength of the gearbox housing 1.

[0021] In order to reduce the processing cost of the gearbox cover 5, this utility model adopts sheet metal stamping to form the gearbox cover 5. The structure made by sheet metal stamping is cheaper than other methods, thus reducing the processing cost of the gearbox cover 5.

[0022] In order to ensure the fit between the motor output shaft and the gear transmission component 3, the present invention mounts the motor 6 on the gearbox cover 5 and positions it by the mounting stop on the gearbox body 1. This method can effectively ensure the stability of the motor 6, thus ensuring the fit between the motor output shaft and the gear transmission component 3.

[0023] In order to prevent the gear transmission component 3 from axial movement, the present invention provides a fixed bracket 4 made by injection molding. The structure made by injection molding has high strength and good stability, which can effectively prevent the gear transmission component 3 from axial movement.

[0024] In operation, the operator first controls the die-casting aluminum backing machine to cast the gearbox housing 1 into aluminum. This one-piece casting method improves the structural strength of the gearbox housing 1. Then, the gearbox cover 5 is formed by sheet metal stamping, which reduces the processing cost of the gearbox cover 5 during production. Finally, after the device is assembled, the motor 6 is started. The output end of the motor 6 can drive the gear transmission component 3 to rotate. At the same time, the fixed bracket 4 can limit the gear transmission component 3 to prevent axial movement. Meanwhile, the running gear transmission component 3 can drive the rotation of the left bearing of the gearbox housing 1. Thus, the device begins to operate.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0026] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
