DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0018] like Figures 1 to 12 As shown, the modular helical planetary reducer described in this embodiment includes an input module 1, a connection module 2 and an output module 3 connected in sequence from bottom to top; The input module 1 includes an input seat 11 and an input shaft 12 rotatably mounted on the input seat 11; a plurality of first clamping assemblies 13 are provided on the upper side of the input seat 11 along the circumferential direction; The connection module 2 includes a connection ring 21; a first clamping groove 211 and a plurality of first driving grooves 212 corresponding one-to-one with the first clamping components 13 are provided on the lower side of the connection ring 21; the first driving grooves 212 cooperate with the first clamping components 13 so that the first clamping components 13 can be unlockably locked with the first clamping grooves 211; a plurality of second clamping components 22 are provided on the upper side of the connection ring 21 along the circumferential direction; The output module 3 includes an output seat 31, an output shaft 32 rotatably arranged on the output seat 31, and a helical planetary gear set 33 arranged on the output shaft 32; a helical ring gear 311 is provided in the output seat 31, which is in transmission meshing with the helical planetary gear set 33; the helical planetary gear set 33 is in transmission meshing with the input shaft 12; thus, when the input shaft 12 drives the helical planetary gear set 33 to rotate, the helical planetary gear set 33 is in transmission meshing with the helical ring gear 311, so that the helical planetary gear set 33 makes a circular motion around the axis of the input shaft 12, so that the helical planetary gear set 33 drives the output shaft 32 to rotate, realizing power transmission between the input shaft 12 and the output shaft 32; a second clamping groove 312 is provided on the lower side of the output seat 31; a plurality of second driving grooves 313 corresponding to the second clamping assembly 22 are also provided on the lower side of the output seat 31; the second driving groove 313 cooperates with the second clamping assembly 22, so that the second clamping assembly 22 can be unlocked and locked with the second clamping groove 312.

[0019] Specifically, when installing the modular helical planetary reducer of this embodiment, the input module 1 and the connection module 2 can be connected to each other first, and the first clamping assembly 13 can be matched with the first driving groove 212 one by one. Then, the first clamping assembly 13 can be unlocked and locked with the first clamping groove 211 through the first driving groove 212, thereby achieving fixed installation between the input module 1 and the connection module 2; Next, the second driving slots 313 of the output module 3 are matched with the second clamping components 22 of the connection module 2 in a one-to-one correspondence. Then, the second clamping components 22 and the second clamping slots 312 are unlockably locked together through the second driving slots 313, thereby achieving fixed installation between the output module 3 and the connection module 2. When disassembly and maintenance are required, the second clamping assembly 22 and the second clamping slot 312 are unlocked through the second drive slot 313, and the output module 3 can be disassembled; similarly, the first clamping assembly 13 and the first clamping slot 211 are unlocked through the first drive slot 212, and the input module 1 and the connection module 2 can be disassembled.

[0020] In this embodiment, a first clamping component 13 is set on the input module 1, a first clamping slot 211 and a first driving slot 212 that cooperate with the first clamping component 13 are set on the connecting module 2, and a second clamping component 22 is set, and a second clamping slot 312 and a second driving slot 313 are set on the output module 3, so that the first driving slot 212 is used to drive the first clamping component 13, so that the first clamping component 13 can be locked or unlocked with the first clamping slot 211, and the second driving slot 313 is used to drive the second clamping component 22, so that the second clamping component 22 can be locked or unlocked with the second clamping slot 312, thereby simplifying the disassembly and installation process of the reducer. Without complex tools and tedious operations, the module replacement can be completed quickly, shortening the downtime of the equipment, improving the equipment maintenance efficiency, and effectively improving the production efficiency.

[0021] In addition, the reducer of this embodiment adopts a modular design, which makes the reducer highly flexible and scalable in function, so that users can replace modules with different functions according to different actual application requirements, such as changing the input and output speed ratio, torque range, etc., thereby realizing the versatility of a reducer under various working conditions, which is conducive to reducing the company's inventory requirements for different types of reducers, and helping to reduce equipment procurement costs and warehousing costs.

[0022] like Figures 4 to 6 、 Figure 8 and Figure 9 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, the first clamping assembly 13 and the second clamping assembly 22 have the same structure, both of which include a clamping slider 41 arranged for radial sliding, a first extrusion block 42 horizontally sliding and penetrating the clamping slider 41, and a clamping pin 43 vertically sliding on the clamping slider 41; the clamping slider 41 is connected to a first spring 411; a second spring 422 is connected between the first extrusion block 42 and the clamping slider 41; a third spring 431 is connected between the clamping pin 43 and the clamping slider 41; the clamping pin 43 can be movably embedded in the first driving groove 212.

[0023] Specifically, the clamping slider 41 of the first clamping assembly 13 is radially slidably installed on the input seat 11, and the clamping slider 41 of the second clamping assembly 22 is radially slidably installed on the connecting ring 21. The first spring 411 of the first clamping assembly 13 is connected between the clamping slider 41 and the input seat 11, and the first spring 411 of the second clamping assembly 22 is connected between the clamping slider 41 and the connecting ring 21; the third spring 431 of the first clamping assembly 13 enables the clamping pin 43 of the first clamping assembly 13 to remain in cooperation with the first drive groove 212, and the third spring 431 of the second clamping assembly 22 enables the clamping pin 43 of the second clamping assembly 22 to remain in cooperation with the second drive groove 313.

[0024] When installing the input module 1 and the connecting module 2, the pin 43 of the first clamping assembly 13 is movably embedded in the first driving groove 212, and the first extrusion block 42 is movably embedded in the first clamping groove 211. Then, the first driving groove 212 cooperates with the pin 43 to drive the clamping slider 41 of the first clamping assembly 13 to overcome the elastic force of the first spring 411 and slide outward. The clamping slider 41 drives the first extrusion block 42 to slide outward, so that the first extrusion block 42 is engaged with the first clamping groove 211. At the same time, the second spring 422 provides a retaining force for the first extrusion block 42, so that the first extrusion block 42 is reliably maintained in a clamped state with the first clamping groove 211, thereby achieving reliable locking of the input seat 11 and the connecting ring 21.

[0025] When disassembling the input module 1 and the connecting module 2, the first driving groove 212 cooperates with the latch 43 to make the clamping slider 41 slide inward, and the clamping slider 41 drives the first extrusion block 42 to slide inward, so that the first extrusion block 42 and the first clamping groove 211 are released from the clamping cooperation, thereby unlocking the input seat 11 and the connecting ring 21. At this time, the input module 1 and the connecting module 2 can be disassembled.

[0026] Similarly, the disassembly and assembly principle of the output module 3 and the connecting module 2 is the same as the disassembly and assembly principle of the input module 1 and the connecting module 2. When the second driving groove 313 and the bayonet 43 cooperate to drive the clamping slider 41 to slide outward, the clamping slider 41 drives the first extrusion block 42 to engage with the second clamping groove 312, thereby locking the output seat 31 and the connecting ring 21; when the second driving groove 313 and the bayonet 43 cooperate to drive the clamping slider 41 to slide inward, the clamping slider 41 drives the first extrusion block 42 to release the engagement with the second clamping groove 312, thereby unlocking the output seat 31 and the connecting ring 21. At this time, the output module 3 and the connecting module 2 can be disassembled.

[0027] like Figure 2 、 Figure 8 and Figure 12 As shown, in the modular helical planetary reducer of this embodiment, in some implementations, a first inclined surface 5 is provided in both the first slot 211 and the second slot 312 ; and the first extrusion block 42 is provided with a second inclined surface 421 for wedge-fitting with the first inclined surface 5 .

[0028] Specifically, when the clamping slider 41 of the first clamping assembly 13 drives the first extrusion block 42 to slide outward, the second inclined surface 421 of the first extrusion block 42 contacts the first inclined surface 5 of the first slot 211, and the second spring 422 enables the first inclined surface 5 to maintain reliable contact with the second inclined surface 421, so that the first extrusion block 42 of the first clamping assembly 13 can be reliably engaged with the first slot 211, thereby locking the input seat 11 and the connecting ring 21; when the clamping slider 41 of the first clamping assembly 13 drives the first extrusion block 42 to slide inward, the second inclined surface 421 of the first extrusion block 42 gradually disengages from the first inclined surface 5 of the first slot 211, thereby releasing the engagement between the first extrusion block 42 of the first clamping assembly 13 and the first slot 211, thereby unlocking the input seat 11 and the connecting ring 21.

[0029] Similarly, when the clamping slider 41 of the second clamping assembly 22 drives the first extrusion block 42 to slide outward, the second inclined surface 421 of the first extrusion block 42 contacts the first inclined surface 5 of the second slot 312, and the second spring 422 enables the first inclined surface 5 to maintain reliable contact with the second inclined surface 421, so that the first extrusion block 42 of the second clamping assembly 22 can be reliably engaged with the second slot 312, thereby locking the output seat 31 and the connecting ring 21; when the clamping slider 41 of the second clamping assembly 22 drives the first extrusion block 42 to slide inward, the second inclined surface 421 of the first extrusion block 42 gradually disengages from the first inclined surface 5 of the second slot 312, thereby releasing the engagement between the first extrusion block 42 of the second clamping assembly 22 and the second slot 312, thereby unlocking the output seat 31 and the connecting ring 21.

[0030] like Figure 5 and Figure 9 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, the clamping slider 41 is embedded with an expansion block 44; the expansion block 44 can expand when heated; the expansion block 44 is embedded with a coil 45 and a resistance rod 46 coaxially arranged with the coil 45; the resistance rod 46 is electrically connected to the coil 45; the first clamping component 13 and the second clamping component 22 both further include a second extrusion block 47; the second extrusion block 47 is arranged below the expansion block 44; the second extrusion block 47 is provided with a third inclined surface 471 in contact with the bottom surface of the expansion block 44, and the high end of the third inclined surface 471 is arranged close to the axis of the connecting ring 21.

[0031] It should be noted that the expansion block 44 can be made of metal, rubber or polytetrafluoroethylene.

[0032] Specifically, when the reducer is working, the coil 45 is energized, causing the resistor rod 46 to generate heat, and the expansion block 44 expands due to the heat. Since the third inclined surface 471 of the second extrusion block 47 is in contact with the expansion block 44, during the expansion process of the expansion block 44, the third inclined surface 471 of the second extrusion block 47 causes the clamping slider 41 to have a tendency to slide outward, thereby further enhancing the wedge locking force between the two modules and improving the structural reliability.

[0033] like Figure 2 、 Figure 4 、 Figure 10 and Figure 12 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, the input shaft 12 is provided with a first magnetic element 14 at a position corresponding to the coil 45 of the first clamping assembly 13; the output shaft 32 is provided with a second magnetic element 34 at a position corresponding to the coil 45 of the second clamping assembly 22.

[0034] Specifically, when the reducer is working, the input shaft 12 drives the first magnetic element 14 to rotate, and the first magnetic element 14 generates a changing magnetic field during the rotation process, so that the coil 45 of the first clamping component 13 generates an induced current, thereby causing the resistance rod 46 of the first clamping component 13 to heat up, causing the expansion block 44 of the first clamping component 13 to expand due to heat, so that the first clamping component 13 and the first clamping slot 211 can be reliably maintained in a clamped state, and the locking is more reliable; at the same time, the input shaft 12 drives the helical planetary gear set 33 to rotate, and the helical planetary gear set 33 cooperates with the helical gear ring 311 to drive the output shaft 32 to rotate, and the output shaft 32 drives the second magnetic element 34 to rotate. The second magnetic element 34 generates a changing magnetic field during the rotation process, so that the coil 45 of the second clamping component 22 generates an induced current, thereby causing the resistance rod 46 of the second clamping component 22 to heat up, causing the expansion block 44 of the second clamping component 22 to expand due to heat, so that the second clamping component 22 and the second clamping slot 312 can be reliably maintained in a clamped state, and the locking is more reliable.

[0035] In the modular helical planetary reducer of this embodiment, in some embodiments, three first magnetic elements 14 and three second magnetic elements 34 are respectively provided, and the three first magnetic elements 14 are evenly distributed along the circumference; the three second magnetic elements 34 are evenly distributed along the circumference; such an arrangement enables the coil 45 of the first clamping component 13 and the coil 45 of the second clamping component 22 to reliably generate sufficient induced current to enable the resistance rod 46 to generate sufficient heat to cause the expansion block 44 to expand.

[0036] like Figure 7 and Figure 11As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, the first drive groove 212 and the second drive groove 313 have the same structure, both of which include a first groove segment 61 that gradually extends from the inside to the outside, the first groove segment 61 is connected to the second groove segment 62 that gradually extends from the outside to the inside, and the second groove segment 62 is connected to the third groove segment 63 that gradually extends from the inside to the outside and toward the first groove segment 61; the third groove segment 63 is connected to the first groove segment 61; the groove depths of the first groove segment 61, the second groove segment 62, and the third groove segment 63 increase successively; a smooth transition inclined surface 631 is provided in the third groove segment 63.

[0037] Specifically, when installing the input module 1 and the connecting module 2, the latch 43 of the first clamping assembly 13 is embedded in the first slot section 61 of the first driving slot 212, and then the connecting ring 21 is rotated forwardly, so that the latch 43 moves relatively along the trajectory of the first slot section 61 until the latch 43 enters the second slot section 62 from the first slot section 61. During the movement of the latch 43 along the first slot section 61, the latch 43 cooperates with the first slot section 61 to drive the clamping slider 41 of the first clamping assembly 13 to slide outward. The clamping slider 41 drives the first extruding block 42 to slide outward through the second spring 422, so that the first extruding block 42 is engaged with the first clamping slot 211. At the same time, the second spring 422 makes the second inclined surface 421 of the first extruding block 42 and the first inclined surface 5 of the first clamping slot 211 wedge-shaped lock more tightly, thereby realizing the locking between the connecting ring 21 and the input seat 11, and thus completing the installation between the input module 1 and the connecting module 2; When it is necessary to disassemble the input module 1 and the connecting module 2, first rotate the connecting ring 21 forward so that the bayonet 43 of the first clamping assembly 13 moves relatively along the trajectory of the second slot section 62 until the bayonet 43 enters the third slot section 63 from the second slot section 62. During the movement of the bayonet 43 along the second slot section 62, the bayonet 43 cooperates with the second slot section 62 to drive the clamping slider 41 of the first clamping assembly 13 to slide inward. The clamping slider 41 drives the first extrusion block 42 to slide inward through the second spring 422, thereby releasing the engagement between the first extrusion block 42 and the first clamping groove 211, thereby unlocking the connecting ring 21 and the input seat 11. At this time, the input module 1 and the connecting module 2 can be disassembled. When the locking cam 31 is in the closed position, the locking cam 31 is in the closed position, and the locking cam 31 is in the closed position, so that the locking cam 31 is in the closed position. When the output module 3 and the connecting module 2 need to be disassembled, the output seat 31 is first rotated forward so that the pin 43 of the second clamping assembly 22 moves relative to each other along the trajectory of the second slot section 62 until the pin 43 enters the third slot section 63 from the second slot section 62. During the movement of the pin 43 along the second slot section 62, the pin 43 cooperates with the second slot section 62 to drive the clamping slider 41 of the second clamping assembly 22 to slide inward. The clamping slider 41 drives the first extrusion block 42 to slide inward through the second spring 422, thereby releasing the engagement between the first extrusion block 42 and the second clamping groove 312, thereby achieving unlocking between the connecting ring 21 and the output seat 31. At this time, the output module 3 and the connecting module 2 can be disassembled.

[0038] like Figure 3 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, three groups of first clamping components 13 are provided; the three groups of first clamping components 13 are evenly distributed along the circumferential direction; such an arrangement makes the connection between the input module 1 and the connection module 2 more reliable.

[0039] like Figure 6 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, three groups of second clamping assemblies 22 are provided; the three groups of second clamping assemblies 22 are evenly distributed along the circumferential direction; such an arrangement makes the connection between the output module 3 and the connection module 2 more reliable.

[0040] like Figure 2 and Figure 12 As shown, in the modular helical planetary reducer of this embodiment, in some embodiments, the output shaft 32 is rotatably connected to the output seat 31 through two bearings 35; the two bearings 35 are arranged at intervals up and down; this arrangement ensures the rotational stability and accuracy of the output shaft 32.
