[0017] In order to make the technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0018] like Figure 1 As shown, an axial deceleration silent motor includes a motor body 2 and a motor housing 1 fixed to the outside of the motor body 2. A hole is opened at one end of the motor housing 1 to transmit output to the output end of the motor body 2. When an external device is connected to realize the drive transmission output, the joint is limited to the inner side of the motor housing 1, thereby achieving the purpose of reducing noise.

[0019] The motor body 2 includes a silent motor structure with built-in encoder feedback and a reduction box.

[0020] like Figure 1 , Figure 2 As shown, a connecting and fixing plate 122 is provided at the other end of the motor housing 1 relative to the opening. The connecting and fixing plate 122 is used to be connected and fixed to the corresponding end of the motor body 2, so that the motor body 2 and the motor housing 1 are detachably connected and fixed as a whole. In the embodiment of the present application, the connecting and fixing plate 122 is connected and fixed to the motor body 2 in the form of bolt fixing. Among them, the reduction box includes a driving shaft 21, a transmission gear 22 meshing with the driving shaft 21 for transmission, and a meshing gear plate 23 connected to the transmission gear 22 for transmission. The meshing gear plate 23 makes a circumferential rotation motion with the driving shaft 21 as the axis, and is clamped with an output long shaft 3 for transmission output. The output long shaft 3 is used to connect with an external device and realize drive transmission output.

[0021] like Figure 2 , Figure 3 As shown, the motor housing 1 is composed of an outer shell 11, an inner shell 12 and a partition cavity 13 located between the outer shell 11 and the inner shell 12. The outer shell 11 and the inner shell 12 are connected and fixed by detachable parts. In the embodiment of the present application, the detachable parts are bolts, latches, etc., which are not described here. One end of the inner shell 12 passes through the outer shell 11 and is connected and fixed to the connecting and fixing plate 122, and the other end of the inner shell 12 is away from the opening of the outer shell 11. Therefore, the inner shell 12 and the outer shell 11 are effectively combined and the motor body 2 is stably fixed inside, which significantly improves the quiet effect.

[0022] It should be noted that the transmission gear 22 is coaxially provided with a connecting synchronous gear 221. The connecting synchronous gear 221 is meshed with a meshing gear 222, and the meshing gear 222 is meshed with the meshing toothed disc 23. Therefore, when the driving shaft 21 makes a circumferential rotational motion, the transmission gear 22 and the connecting synchronous gear 221 will be driven to make a circumferential rotation at the same angular velocity, and the rotation axes of the transmission gear 22 and the connecting synchronous gear 221 are perpendicular to the rotation axis of the driving shaft 21, and then when the connecting synchronous gear 221, which has a diameter smaller than that of the transmission gear 22, drives the meshing gear 222 to make a circumferential rotational motion, the purpose of effectively driving the meshing toothed disc 23 to rotate is achieved. Therefore, the reducer has the effects of simple and compact structure, convenient production and installation, small size, and large torque transmission, and the driving shaft 21 and the transmission gear 22 meshed with the driving shaft 21 have the functions of low transmission noise, good effect and reverse self-locking. The meshing gear 222 and the meshing toothed disc 23 form a connection structure of cylindrical teeth and crown-shaped toothed discs, thereby achieving high transmission efficiency and smooth transmission effects. Compared with the existing bevel gear connection structure, the installation requirements are significantly reduced.

[0023] like Figure 1 , Figure 2 As shown, there are two groups of transmission gears 22 and they are symmetrically distributed on both sides of the driving shaft 21, which will significantly improve the driving rotation stability, force uniformity and strength of the meshing gear disc 23. A limit cover disc 24 is provided on the side of the meshing gear disc 23 away from the transmission gear 22. The limit cover disc 24 is provided with a limit buckle 241 that is plugged and fixed with the inner shell 12, so that the limit cover disc 24 limits the meshing gear disc 23, thereby improving the connection stability between the meshing gear disc 23 and the meshing gear 222. At the same time, a wire opening 121 is provided at the corresponding end of the inner shell 12, and the motor body 2 is provided with an external wire group 26 that passes through the wire opening 121, so as to achieve the purpose of optimizing the structural integrity of the motor body 2 and the motor housing 1.

[0024] In summary, the present application provides an axial deceleration silent motor, which protects the motor body 2 through the motor housing 1 and achieves an effective silent effect. Combined with the use of a driving shaft 21 in the motor body 2 to drive the transmission gear 22 to rotate, and then drive the circumferential rotation of the meshing gear plate 23 to achieve the purpose of axial deceleration drive output, the axial deceleration silent motor has the purpose of effectively achieving silent operation and improving energy efficiency.
