[0077] Among them, one end of the driving mechanism 1 has a rotating shaft 101, and the driving mechanism 1 is used to provide driving force for the coaxial differential multi-output device through the rotating shaft 101. Specifically, when the driving mechanism 1 is started, the rotating shaft 101 rotates under the driving action of the driving mechanism 1. The driving mechanism 1 can be, but is not limited to, powered by a motor.

[0078] The first output assembly 2 has a first output interface 201, which is in transmission connection with the rotating shaft 101.

The second output assembly 3 is connected to the rotating shaft 101 in a transmission manner. When the rotating shaft 101 rotates, the second output interface 301 in the second output assembly 3 can be driven to rotate, so that the second output interface 301 can output a second speed different from the first speed. Of course, it can be understood that when the second output assembly 3 also has a third output interface 307, a fourth output interface and an nth output interface, under the condition that the rotating shaft 101 rotates, the third output interface 307, the fourth output interface and more output interfaces in the second output assembly 3 can also be driven to rotate coaxially. The second output assembly 3 and the first output assembly 2 are respectively arranged on the rotating shaft 101 and are coaxial with the rotating shaft 101. That is, the second output component 3 and the first output component 2 are arranged in layers along the circumference of the rotating shaft 101, and the rotating shaft 101 rotates and drives the second output component 3 and each output interface in the first output component 2 to be arranged coaxially, and each output interface can rotate and output corresponding different speeds. Specifically, the third output interface 307 and the fourth output interface can have different output rotation directions, for example, the third output interface 307 rotates forward, and the fourth output interface rotates reversely. The first output interface 201 and the second output interface 301 rotate coaxially with the rotating shaft 101 respectively, and the first output interface 201 is located on the outside of the second output interface 301. Specifically, the rotation speed of the first output interface 201 located on the outer ring side is higher than the rotation speed of the second output interface 301 located on the inner ring side.

[0080] The embodiment of the utility model adopts a first output component 2 in combination with a second output component 3 and adopts a planetary gear train structure, which can not only realize coaxial low differential two-speed output or internal low-speed and external high-speed two-speed flexible reduction ratio output, but also realize distributed low-speed, medium-speed, and high-speed synchronous multi-speed output. The device can not only realize coaxial inner shaft low-speed output, but also synchronize multi-speed output on the second output component. The device is suitable for a host of a multifunctional output accessory that is adapted to a certain interface alone or a host of a device that is synchronously adapted to a combination of interfaces with different speeds and / or rotation directions for stirring and cutting, centrifugal juice filtering, low-speed grinding, spiral feeding, etc. Its multi-speed output is more flexible to use and has a wider range of applicability.

A gear box cover 203 can be arranged at the other end of the gear box 202, and the two can be fixed by screws, and the gear box cover 203 is sealed and connected with the gear box 202.

The rotating shaft 101 passes through the center hole of the first output sun gear 204 and is coaxially fixedly connected with the first output sun gear 204.

[0085] The first planetary bracket 205 is cylindrical with a blocking plate at one end, and a through hole is provided at the center of the blocking plate for the rotation shaft 101 to extend into.

[0086] At least one first output planetary gear 206 is meshed with the first output sun gear 204 and rotates under the driving action of the first output sun gear 204. For example, there are three first output planetary gears 206, and the three first output planetary gears 206 are evenly arranged on the outer periphery of the first output sun gear 204 with the first output sun gear 204 as the center, and meshed with the first output sun gear 204 to achieve smooth transmission of power. Of course, it can be understood that the first output planetary gears 206 can also be four, five, etc., and the number of the first output planetary gears 206 is not specifically required. A first axle 209 is provided at the center of the first output planetary gear 206, and one end of the first output planetary gear 206 is connected to one end of the first planetary bracket 205 through the first axle 209; specifically, a connecting hole is provided on the plate surface of the blocking plate facing the first output planetary gear 206, and the first rotating shaft 101 cooperates with the connecting hole to achieve the connection between the first output planetary gear 206 and the first planetary bracket 205.

The other end of the first output member 208 extends out from the gear box cover 203, and a first output interface 201 is formed at this end, and the first output interface 201 outputs a first rotational speed.

[0089] By configuring the first output assembly 2 to include a first output sun gear 204, a first planetary carrier 205, at least one first output planetary gear 206, a first outer gear ring 207 and a first output member 208, a first output interface 201 with a first rotational speed and stable output is provided for the coaxial differential multi-output device.

[0090] In the first embodiment of the present application, combined with Figure 1 The second output assembly 3 includes a second planetary gear train structure, and the second planetary gear train structure includes: a second output primary sun gear 302 , at least one second output primary planetary gear 303 and a second output primary planetary carrier 304 .

Specifically, a threaded hole is provided at one end of the second output primary sun gear 302, and an external thread is provided at the end of the rotating shaft 101. The external thread of the rotating shaft 101 cooperates with the threaded hole at one end of the second output primary sun gear 302 to achieve a fixed connection between the second output primary sun gear 302 and the rotating shaft 101. The second output primary sun gear 302 is coaxially arranged on the rotating shaft 101 with the first output sun gear 204, and rotates under the driving action of the rotating shaft 101. Specifically, when the rotating shaft 101 rotates, the second output primary sun gear 302 and the first output sun gear 204 are driven to rotate synchronously.

[0092] At least one second output first-stage planetary gear 303 is meshed with the second output first-stage sun gear 302 and rotates under the driving action of the second output first-stage sun gear 302. For example, there are three second output first-stage planetary gears 303, and the three second output first-stage planetary gears 303 are centered on the second output first-stage sun gear 302, evenly arranged on the outside of the second output first-stage sun gear 302 and meshed with the second output first-stage sun gear 302 to achieve smooth transmission of power. Of course, it can be understood that the second output first-stage planetary gears 303 can also be four, five, etc., and the number of the second output first-stage planetary gears 303 is not specifically required. Internal teeth are provided on the inner wall of the other end of the first output planetary bracket, and the three second output first-stage planetary gears 303 are meshed with the internal teeth of the first output planetary bracket.

Since the first output planetary support is fixed to the gear box 202 and does not move, when the rotating shaft 101 rotates, the second output first-stage planetary gears 303, the first planetary support fixing plate and the second output first-stage planetary support 304 rotate around the second output first-stage sun gear 302 as the center.

[0094] By setting the second output component 3 to a structural form including a second output first-stage sun gear 302, at least one second output first-stage planetary gear 303 and a second output first-stage planetary carrier 304, a second output interface 301 with stable output is provided for the coaxial differential multi-output device, and the second output interface 301 has a second speed different from the first speed.

The third speed is the same as the speed of the second output first-stage sun gear 302 and the speed of the rotating shaft 101. Specifically, a through hole is provided in the center of the blocking plate of the second output first-stage planetary bracket 304, and the other end of the second output first-stage sun gear 302 passes through the through hole and extends into the second output first-stage planetary bracket 304, and the third output interface 307 formed at the other end of the second output first-stage sun gear 302 is located in the second output first-stage planetary bracket 304.

[0096] A third output interface 307 is formed through the other end of the second output primary sun gear 302 , and the third output interface 307 of the coaxial differential multi-output device has a third speed different from the first speed and the second speed.

[0097] In the third embodiment of the present application, combined with Figure 3 , Figure 7 , Figure 8 and Fig. 9 The second output assembly 3 further includes a second planetary gear train structure and a third planetary gear train structure. The second planetary gear train structure includes a second output primary sun gear 302 , at least one second output primary planetary gear 303 , and a second output primary planetary carrier 304 .

[0098] One end of the second output primary sun gear 302 is connected to the rotating shaft 101 , and the second output primary sun gear 302 is coaxially arranged on the rotating shaft 101 with the first output sun gear 204 ; and rotates under the driving action of the rotating shaft 101 .

[0099] At least one second output primary planetary gear 303 meshes with the second output primary sun gear 302 and rotates under the driving action of the second output primary sun gear 302. The inner wall of the other end of the first planetary support 205 is provided with internal teeth, and at least one second output primary planetary gear 303 meshes with the internal teeth of the first planetary support 205.

[0100] One end of the second output first-stage planetary support 304 is connected to the center of at least one second output first-stage planetary gear 303 via a second axle 305 , and rotates driven by the at least one second output first-stage planetary gear 303 .

[0101] The third planetary gear train structure includes a second output secondary sun gear 308 , at least one second output secondary planet gear 309 , and a second output secondary planet carrier 310 .

[0102] One end of the second output secondary sun gear 308 is disposed at the center of the other end of the second output primary planetary support 304 and rotates synchronously with the second output primary planetary support 304. The other end of the second output secondary sun gear 308 forms a third output interface 307.

[0103] At least one second output secondary planetary gear 309 is meshed with the second output secondary sun gear 308 and rotates under the driving action of the second output secondary sun gear 308. For example, there are three second output secondary planetary gears 309, and the three second output secondary planetary gears 309 are arranged with the second output secondary sun gear 308 as the center, and are respectively meshed with the second output secondary sun gear 308, so as to rotate simultaneously under the driving action of the second output secondary sun gear 308 to achieve smooth transmission of power. Of course, it can be understood that the second output secondary planetary gears 309 can also be four, five, etc., and the number of the second output secondary planetary gears 309 is not specifically required. The three second output secondary planetary gears 309 are meshed with the internal teeth of the first planetary bracket 205.

[0104] Continuing with the above embodiment, one end of the second output secondary planetary support 310 is connected to the center of the three second output secondary planetary gears 309 through three third axles 315 respectively, and rotates under the drive of the three second output secondary planetary gears 309.

The principle that the second output secondary planetary gear 309 drives the second output secondary planetary support 310 to rotate is the same as the principle that the second output primary planetary gear 303 drives the second output primary planetary support 304 to rotate, and will not be repeated here. The other end of the second output secondary planetary support 310 forms a second output interface 301, and the second output interface 301 outputs a second rotation speed.

[0105] By setting the second conveying assembly as a two-stage planetary gear train mechanism including a second planetary gear train structure and a third planetary gear train structure, the other end of the second output secondary sun gear 308 forms a third output interface 307, while the other end of the second output secondary planetary bracket 310 can also form a second output interface 301, thereby realizing low-speed, medium-speed, and high-speed synchronous multi-speed output of the coaxial differential multi-output device.

[0106] In one embodiment of the present application, the second output secondary sun gear 308 also forms a fourth output interface. Similarly, the second output assembly 3 sequentially superimposes other more planetary gear train mechanisms that are different from the first planetary gear train structure, the second planetary gear train structure, and the third planetary gear train structure, so that more output interfaces can be formed, so that the coaxial differential multi-output device has multiple output interfaces with different speeds to better meet product requirements. For example, a fourth planetary gear train structure is provided on the second output secondary sun gear 308 to form a fifth output interface. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0109] At least one second output primary planetary gear 303 meshes with the second output primary sun gear 302 and rotates under the driving action of the second output primary sun gear 302. The inner wall of the other end of the first planetary support 205 is provided with internal teeth, and at least one second output primary planetary gear 303 meshes with the internal teeth of the first planetary support 205.

[0110] One end of the second output first-stage planetary support 304 is connected to the center of at least one second output first-stage planetary gear 303 via a second axle 305 , and rotates driven by the at least one second output first-stage planetary gear 303 .

[0111] The third planetary gear train structure includes at least one second output secondary planet gear 309 and a second output secondary planet carrier 310 .

[0112] At least one second output secondary planetary gear 309 is meshed with the second output primary sun gear 302 and rotates under the driving action of the second output primary sun gear 302. There can be three second output secondary planetary gears 309, and the three second output secondary planetary gears 309 are evenly arranged with the second output primary sun gear 302 as the center, and are respectively meshed with the second output primary sun gear 302 to achieve smooth transmission of power. The three second output secondary planetary gears 309 are respectively meshed with the internal teeth of the first planetary bracket 205. Among them, the other end of the second output primary sun gear 302 forms a third output interface 307, and the third output interface 307 outputs a third speed different from the first speed and the second speed.

[0113] Continuing with the above embodiment, one end of the second output secondary planetary support 310 is connected to the centers of the three second output secondary planetary gears 309 through three third wheel shafts 315, and rotates under the drive of the three second output secondary planetary gears 309. The principle of the second output secondary planetary gear 309 driving the second output secondary planetary support 310 to rotate is the same as the principle of the second output primary planetary gear 303 driving the second output primary planetary support 304 to rotate, and will not be repeated here. The other end of the second output secondary planetary support 310 forms a second output interface 301, so that the second output interface 301 outputs a second speed different from the first speed.

[0114] By setting the second conveying assembly as a two-stage planetary gear train mechanism including a second planetary gear train structure and a third planetary gear train structure, the other end of the second output first-stage sun gear 302 forms a third output interface 307, while the other end of the second output second-stage planetary bracket 310 can also form a second output interface 301, thereby realizing low-speed, medium-speed, and high-speed synchronous multi-speed output of the coaxial differential multi-output device.

[0115] In one embodiment of the present application, at least part of the output interface is provided with a coupling driving rotation clamp or buckle 316 structure in its rotation direction. Of course, other structural forms can also be provided to achieve the connection between the output interface and the driven structure, so as to achieve a stable connection between the output interface and the driven structure. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.
