Referring to fig. 1 and 2, a rotating mechanism 10 according to an embodiment of the present invention is used for a food processor, and the rotating mechanism 10 includes a first knife shaft 11, a second knife shaft 12 and a gear transmission assembly 13. The first cutter shaft 11 and the second cutter shaft 12 are coaxially arranged. The gear transmission assembly 13 comprises a sun gear 131, a ring gear structure 132 and planet gears 14. The sun gear 131 is fixed to the first spindle 11. The gear ring structure 132 is fixedly connected with the second cutter shaft 12. The planet gear 14 includes a first gear 141 and a second gear 142, and the first gear 141 and the second gear 142 are fixedly connected and coaxially disposed. The first gear 141 meshes with the sun gear 131. The second gear 142 meshes with the ring gear structure 132. The first cutter shaft 11 drives the second cutter shaft 12 to rotate through a gear transmission assembly 13.

The gear transmission assembly 13 in the rotary mechanism 10 according to the embodiment of the present invention is configured to divide the planet gear 14 into the first gear 141 and the second gear 142, so that the first gear 141 and the second gear 142 are respectively engaged with the sun gear 131 and the ring gear structure 132, thereby improving the rotation efficiency of the ring gear structure 132 and enhancing the rotation efficiency of the rotary mechanism 10.

In addition, since the first gear 141 and the second gear 142 are coaxially disposed, the first gear 141 and the second gear 142 do not rotate off-axis, and noise generated by the off-axis rotation of the first gear 141 and the second gear 142 does not occur. Further, the stability of the gear transmission is good, and the noise generated by the rotation mechanism 10 can be reduced. Therefore, the rotating mechanism 10 according to the embodiment of the present invention also has an effect of reducing noise during operation.

Specifically, since the first spindle 11 is fixed with the sun gear 131, the sun gear 131 rotates with the rotation of the first spindle 11. Since the first gear 141 is engaged with the sun gear 131. The rotation of the sun gear 131 drives the first gear 141 to rotate. Since the second gear 142 is fixedly connected with the first gear 141. Therefore, when the first gear 141 rotates, the second gear 142 also rotates along with the rotation of the first gear 141. Since the ring gear structure 132 is in mesh with the second gear 142. Rotation of the second gear 142 causes the ring gear structure 132 to rotate. Since the second arbor 12 is fixedly connected to the ring gear structure 132. Therefore, the rotation of the gear ring structure 132 will drive the rotation of the second arbor 12. In this way, when the first arbor 11 rotates, the second arbor 12 can be driven to rotate by the central gear 131, the first gear 141, the second gear 142 and the gear ring structure 132.

Referring to fig. 3, in some embodiments, the module of the first gear 141 is smaller than the module of the second gear 142.

Since the sun gear 131 is engaged with the first gear 141, the first gear 141 and the second gear 142 are coaxially and fixedly connected. At this time, the central gear 131 rotates to drive the first gear 141 to rotate, and the number of rotations of the first gear 141 is the same as that of the rotations of the second gear 142.

In one example, the module m1 of the first gear 141 may be 1 and the module m2 of the second gear 142 may be 2. Of course, the module m1 of the first gear 141 and the module m2 of the second gear 142 are not only 1, but m1 is only required to be larger than m 2.

Because the module of the second gear 142 is greater than the module of the first gear 141, at this time, under the condition of the same number of teeth, the diameter of the second gear 142 is greater than the diameter of the first gear 141, and under the condition that the rotation speeds of the first gear 141 and the second gear 142 are the same, the torque of the second gear 142 is greater than the torque of the first gear 141, so that the torque of the second knife shaft 12 is increased, and further, the second knife shaft 12 still has a larger torque under the condition of a low rotation speed, which is beneficial for a knife mounted on the second knife shaft 12 to cut and stir food.

In particular, the modules of first gear 141 and second gear 142 may be varied according to different requirements, so that there is a greater choice of the transmission ratio between ring gear 1321 and sun gear 131. In this way, a greater choice of transmission ratios between the first arbor 11 and the second arbor 12 can be made. The rotational efficiency of the rotary mechanism 10 is achieved by changing the transmission ratio between the first and

second knife shafts

11, 12.

Further, the transmission ratio between the first arbor 11 and the second arbor 12 may be between 0 and 100, such that the rotation speed of the first arbor 11 is greater than or equal to the rotation speed of the second arbor 12. The preferred transmission ratio between the first shaft 11 and the second shaft 12 is 0.95. Experiments have shown that a transmission ratio of 0.95 between the first and

second shafts

11, 12 is preferred to make the rotating mechanism 10 more efficient.

Further, the sun gear 131, the first gear 141, the second gear 142, and the ring gear 1321 may be made of fine steel. The refined steel has the characteristics of high hardness and smooth surface. Therefore, the sun gear 131, the first gear 141, the second gear 142, and the ring gear 1321, which are made of the refined steel, have higher wear resistance and smaller frictional force. The life of the rotary mechanism 10 can be increased while reducing noise of the rotary mechanism 10. Of course, the sun gear 131, the first gear 141, the second gear 142, and the ring gear 1321 may be made of not only fine steel but also different materials according to different situations. For example, the sun gear 131, the first gear 141, the second gear 142, and the ring gear 1321 may be made of cast iron.

Referring to fig. 4, in one example, the sun gear 131 is provided with a connection hole 1311, and opposite ends of the connection hole 1311 are provided with openings 13111. The first arbor 11 is provided with a projection 115 for fitting into the opening 13111. The arrangement enables the central gear 131 to be connected with the first cutter shaft 11 more tightly, improves the connection stability of the central gear 131 and the first cutter shaft 11, and prevents the central gear 131 from rotating relative to the first cutter shaft 11.

Further, the first and

second knife shafts

11 and 12 are cylindrical.

In some embodiments, the number of the planetary gears 14 is multiple, and the plurality of planetary gears 14 are distributed at intervals around the circumference of the sun gear 131.

The plurality of planet wheels 14 improve the transmission stability of the gear transmission assembly 13, not only can reduce the noise generated by the gear transmission assembly, but also can improve the rotation efficiency of the rotating mechanism 10.

Specifically, the number of the planet wheels 14 may be 1-8. Preferably, in the present embodiment, the number of the planetary gears 14 is 3.

Further, the first gear 141 and the second gear 142 are integrally formed. The connection between the first gear 141 and the second gear 142 is tighter due to the integral molding, the first gear 141 and the second gear 142 are not loosened, and the service life of the planet wheel 14 can be prolonged.

Referring to FIG. 5, in some embodiments, ring gear structure 132 includes a ring gear 1321 and a disk 1322. The ring gear 1321 meshes with the second gear 142. Disk 1322 covers ring gear 1321.

A fixed connection refers to a connection in which the two elements do not rotate relative to each other. For example, the disc 1322 may be screwed to the ring gear 1321.

The arrangement of the wheel disc 1322 and the gear ring 1321 enables the gear ring structure 132 to be more easily assembled, and when the gear ring 1321 or the wheel disc 1322 is damaged, the wheel disc can be detached and replaced independently, so that the assembly is more convenient.

Specifically, disk 1322 is fabricated from precision steel. The refined steel has the characteristics of high hardness and smooth surface. Thus, the disc 1322, which is made of refined steel, has a higher wear resistance and a lower friction. The life of the rotary mechanism 10 can be increased while reducing noise of the rotary mechanism 10. Of course, the disc 1322 may be made of different materials according to different situations, rather than just fine steel. For example, disk 1322 may be formed from cast iron.

Referring to fig. 5-7, in some embodiments, the rim 1321 is formed with a plurality of recesses 13211. The disc 1322 is provided with a plurality of protrusions 13221 corresponding one-to-one to the plurality of recesses 13211. Each projection 13221 snaps into a corresponding recess 13211 to prevent relative rotation of the disc 1322 with respect to the ring gear 1321.

The arrangement of the groove 13211 and the projection 13221 improves the stability between the disc 1322 and the gear ring 1321, the disc 1322 is limited to rotate relative to the gear ring 1321 by the groove 13211 and the projection 13221, and the disc 1322 and the gear ring 1321 can be positioned, so that the structure is simple and the effect is good. In this way, during operation of rotary mechanism 10, there is no reduction in the rotational efficiency of rotary mechanism 10 caused by the rotation of disk 1322 relative to ring gear 1321.

Specifically, the arc length formed between two adjacent recesses 13211 is the same, and thus the balance between the transmission of large torque and the high rotation speed between the ring gear 1321 and the disk 1322 can be achieved, and the generation of noise can be reduced.

In one example, the ring gear 1321 is peripherally provided with a first flange 13212, the first flange 13212 is provided around the ring gear 1321, and a recess 13211 is formed in the first flange 13212. The periphery of disk 1322 is provided with an annular step 13222 that is matingly coupled to first flange 13212, and projection 13221 is located on annular step 13222. The insertion of annular step 13222 into first flange 13212 provides a tighter connection between disk 1322 and ring gear 1321. In this way, the disc 1322 and the ring gear 1321 do not loosen during rotation of the ring gear structure 132, and noise generation is reduced.

Further, the ring gear 1321 and the disc 1322 may be fixed using screws. The screw fixation can make the connection between the gear ring 1321 and the wheel disc 1322 more stable, and looseness is not easy to occur.

Referring to fig. 5, 8 and 9, the wheel disc 1322 is provided with a fitting groove 13223, a second flange 13224 is provided at the periphery of the fitting groove 13223, a third flange 122 is provided on the side of the second knife shaft 12 facing the wheel disc 1322, and the third flange 122 is fitted into the fitting groove 13223 and is surrounded by the second flange 13224. The second knife shaft 12 is more stable and is not easy to loosen or topple over due to the wrapping of the second flange 13224, and the rotating efficiency of the rotating mechanism 10 is improved.

Further, the bottom wall 13227 of the fitting groove 13223 is provided with a plurality of first screw holes 13226, the third flange 122 is provided with a plurality of second screw holes 123 matching with the first screw holes 13226, and the second arbor 12 is fixedly connected with the disk 1322 through the first screw holes 13226 and the second screw holes 123. The connection between the second knife shaft 12 and the wheel disc 1322 can be more stable through screw fixation, the situation that the second knife shaft 12 topples or loosens relative to the wheel disc 1322 in the rotating process can not occur, and the rotating efficiency of the rotating mechanism 10 is improved. It is understood that the second knife shaft 12 and the disc 1322 can be fixed not only by screws, but also in different manners according to different situations. For example, the second arbor 12 and disk 1322 may be secured using expansion pins.

In some embodiments, the first arbor 11 is threaded through the second arbor 12. One end of the first cutter shaft 11 far away from the central gear 131 extends out of the second cutter shaft 12. The first cutter shaft 11 and the second cutter shaft 12 can rotate relatively.

So set up, can not influence rotation each other between first arbor 11 and the second arbor 12 each other, so make rotary mechanism 10 can realize that first arbor 11 and second arbor 12 rotate simultaneously, promote rotary mechanism 10's rotation performance.

Specifically, referring to fig. 5, an accommodating area 16 is formed in the second arbor 12 and penetrates up and down, the first arbor 11 is located in the accommodating area 16, and an end of the first arbor 11 away from the wheel disc 1322 extends out of the accommodating area 16. The second knife shaft 12 is provided with a first bearing 161 and a second bearing 162, and the first knife shaft 11 passes through the first bearing 161 and the second bearing 162 to realize that the second knife shaft 12 can rotate relative to the first knife shaft 11.

Referring to fig. 2, in some embodiments, the rotating mechanism 10 further includes a housing 15. The case 15 includes a housing 151 and a bottom cover 152. The bottom cover 152 is fixedly coupled to the housing 151. The housing 151 and the bottom cover 152 together define a placement space 153. The gear transmission assembly 13 is accommodated in the accommodating space 153. The planet gears 14 are rotatably provided at the bottom cover 152. The first knife shaft 11 and the second knife shaft 12 penetrate through the outer shell 151 and extend out of the outer shell 151.

The arrangement of the placement area of the housing 15 enables the gear transmission assembly 13 to be stably arranged on the housing 15, so that the structure is more compact, and the reduction of the rotation efficiency of the rotating mechanism 10 caused by the movement of the gear transmission assembly 13 can not occur when the rotating mechanism 10 rotates. And the housing 15 can protect the gear transmission assembly 13 from exposing the gear transmission assembly 13, so that the gear transmission assembly 13 is not interfered by the outside to affect the rotation efficiency of the gear transmission assembly 13.

Specifically, the case 151 and the bottom cover 152 may be made of fine steel. The refined steel has the characteristics of high hardness and smooth surface. Therefore, the case 151 and the bottom cover 152 made of the fine steel can make the case 15 harder and less vulnerable to damage. It will be appreciated that the housing 151 and bottom cover 152 may be made of more than just fine steel. Can be made of different materials according to different requirements. For example, the housing 151 and the bottom cover 152 may be made of iron alloy.

Further, the housing 151 and the bottom cover 152 may be fixedly connected in a snap-fit manner. Of course, the housing 151 and the bottom cover 152 may be connected in a snap-fit manner. And may also be fixed by screws or other fixing methods, which are not limited herein.

Referring to fig. 10, in some embodiments, the gear assembly 13 further includes a wheel frame 133 received in the placing space 153. The planet gears 14 are located between the wheel carrier 133 and the bottom cover 152. The carrier 133 presses the planetary gears 14 to prevent the planetary gears 14 from moving relative to the bottom cover 152 in the axial direction of the planetary gears 14.

The planet wheel 14 is arranged between the wheel frame 133 and the bottom cover 152, so that the stability of the planet wheel 14 can be effectively improved, the axial movement of the planet wheel 14 can not occur, the noise generated in the rotation process of the planet wheel 14 can be reduced, and the service life of the planet wheel 14 can be prolonged.

Referring to fig. 2 and 10, in some embodiments, the bottom cover 152 is provided with a plurality of axles 1521, the planet wheels 14 are sleeved on the axles 1521, and the planet wheels 14 can rotate relative to the axles 1521.

The arrangement of the axle 1521 makes the planet gears 14 more stable between the wheel carrier 133 and the bottom cover 152, preventing the planet gears 14 from moving relative to the bottom cover 152 in the axial direction of the planet gears 14.

Specifically, the axle 1521 is fixedly disposed on the bottom cover 152, and the axle 1521 may be fixedly connected to the bottom cover 152 in a screw-fixing manner.

In other embodiments, the axle 1521 may be integrally formed with the bottom cover 152.
