Abstract
Description
Technical Field
[0001] The invention belongs to the field of mechanical transmission, and in particular relates to a clutch structure and a control box. Background Art
[0002] Gear transmission is widely used in the field of mechanical transmission due to its transmission stability. The gear set connects the motor and the output shaft to convert the torque of the motor into the torque of the output shaft. In actual application, there is a demand to add a torque input method for the output shaft, such as manually driving the output shaft to rotate. This is to replace the motor drive with manual drive in the event of motor failure or on-site emergency operation or maintenance. At this time, since the output shaft and the motor are meshed and connected by the gear set, the rotation of the output shaft will drive the reverse rotation of the gear set. Therefore, it is necessary to improve the gear set so that the rotation of the output shaft will not be transmitted to the motor. That is, one-way transmission between the gear set and the output shaft is realized. Summary of the invention

[0046] Embodiment 1
[0047] Please refer to Figures 1 to 8 The present embodiment provides a clutch structure 101 , including a clutch shaft 10 , and a first rotating wheel 20 , a second rotating wheel 30 and a clutch assembly 40 sleeved on the clutch shaft 10 .
[0048] The clutch shaft 10 limits the horizontal movement of the first rotating wheel 20 , the second rotating wheel 30 and the clutch assembly 40 . In addition, the central axis of the clutch shaft 10 is the rotation axis of the first rotating wheel 20 , the second rotating wheel 30 and the clutch assembly 40 .
[0049] The clutch assembly 40 includes a clutch sleeve 41, a rotating disk 42 and a forward-rotating roller 43. The clutch sleeve 41 is connected to the second rotating wheel 30. The clutch sleeve 41 is sleeved on the clutch shaft 10 and spaced from the clutch shaft 10 to form a clutch cavity. The rotating disk 42 is connected to the first rotating wheel 20. The rotating disk 42 is sleeved on the clutch shaft 10 and is located in the clutch cavity. The rotating disk 42 has a forward-rotating groove 421 opened inwardly on its outer surface. The forward-rotating groove 421 extends in the circumferential direction and has a forward-rotating separation position and a forward-rotating coordination position. The groove depth of the forward-rotating groove 421 is gradually reduced from the forward-rotating separation position to the forward-rotating coordination position. The forward-rotating roller 43 is located in the forward-rotating groove 421.
[0050] The direction from the shallow part of the clockwise groove 421 to the deep part of the clockwise groove 421 is the clockwise direction M1.
[0051] When the first rotating wheel 20 serves as a driving wheel and rotates in the clockwise direction M1, it drives the rotating disk 42 to rotate and moves the forward-rotating roller 43 from the forward-rotating separation position to the forward-rotating cooperation position, so that the rotating disk 42, the forward-rotating roller 43 and the clutch sleeve 41 are in an engaged state and drive the clutch sleeve 41 to rotate. When the second rotating wheel 30 serves as a driving wheel and rotates in the clockwise direction M1, it drives the clutch sleeve 41 to rotate and moves the forward-rotating roller 43 from the forward-rotating cooperation position to the forward-rotating separation position, so that the forward-rotating roller 43 and the clutch sleeve 41 are separated from each other.
[0052] The transmission process between the first rotating wheel 20 and the second rotating wheel 30 is as follows:
[0053] Please refer to Figure 4 and Figure 5 When the first rotating wheel 20 serves as the driving wheel and rotates in the clockwise direction M1, the turntable 42 rotates therewith due to its connection with the first rotating wheel 20, and the forward-rotating roller 43 located in the forward-rotating groove 421 remains in the original position under the action of inertia until the two sides of the forward-rotating roller 43 are abutted by the rotating disk 42 and the clutch sleeve 41 (moves relative to the rotating disk 42 and moves from the forward-rotating separation position to the forward-rotating coordination position). At this time, the forward-rotating roller 43 is clamped by the rotating disk 42 and the clutch sleeve 41 so that the forward-rotating roller 43, the rotating disk 42 and the clutch sleeve 41 are in a locked state, and the forward-rotating roller 43 and the clutch sleeve 41 rotate together with the rotating disk 42, and the clutch sleeve 41 is connected to the second rotating wheel 30 so that the second rotating wheel 30 also rotates therewith.
[0054] Please refer to Figure 4 and Figure 6 When the second rotating wheel 30 acts as the driving wheel and rotates in the clockwise direction M1, the clutch sleeve 41 rotates with the second rotating wheel 30 because it is connected to the second rotating wheel 30. If the forward-rotating roller 43 is in the forward-rotating cooperative position, the forward-rotating roller 43 is subjected to the traction force generated by the friction of the clutch sleeve 41 and moves to the forward-rotating separation position, so that the forward-rotating roller 43 and the clutch sleeve 41 are separated from each other. The clutch sleeve 41 idles relative to the rotating disk 42. Therefore, the torque of the clutch sleeve 41 cannot be transmitted to the rotating disk 42, and the first rotating wheel 20 connected to the rotating disk 42 cannot be driven.
[0055] From the above analysis, it can be obtained that the setting of the clutch assembly 40 enables the first rotating wheel 20 to drive the second rotating wheel 30 to rotate synchronously when it rotates in the clockwise direction M1 as the driving wheel, while the second rotating wheel 30 cannot drive the first rotating wheel 20 to rotate synchronously when it rotates in the clockwise direction M1 as the driving wheel. The relative positions of the forward groove 421 and the reverse groove 423 can be set by those skilled in the art to achieve linkage and idling in different directions. For example, if the reverse groove 423 is located in front of the forward groove 421 in the clockwise direction, then the first rotating wheel 20 can drive the second rotating wheel 30 to rotate when it rotates counterclockwise, but the second rotating wheel 30 cannot be transmitted to the first rotating wheel 20. On the contrary, if the reverse groove 423 is located in front of the forward groove 421 in the counterclockwise direction, then the first rotating wheel 20 can drive the second rotating wheel 30 to rotate when it rotates clockwise, but the second rotating wheel 30 cannot be transmitted to the first rotating wheel 20.
[0056] In another embodiment of the present application, the turntable 42 is provided with an unlocking groove 422 on its outer surface, the unlocking groove 422 is connected to the forward-rotating groove 421 and is located on the shallow side of the forward-rotating groove 421; the clutch assembly 40 also includes a rib 44, and the rib 44 is located in the unlocking groove 422; when the second rotating wheel 30 acts as a driving wheel and rotates in the counterclockwise direction M2, it drives the clutch sleeve 41 to rotate, and the rib 44 rotates in the opposite direction relative to the clutch sleeve 41 under the action of its inertia, so that the forward-rotating roller 43 located in the forward-rotating cooperative position moves to the forward-rotating separation position, so that the forward-rotating roller 43 and the clutch sleeve 41 are separated from each other.
[0057] When the second rotating wheel 30 serves as the driving wheel and rotates in the counterclockwise direction M2, if the clockwise roller 43 is in the clockwise separation position, then undoubtedly, the clutch sleeve 41 cannot transmit the torque of the second rotating wheel 30 to the rotating disk 42 . If the forward-rotating roller 43 is located in the forward-rotating cooperative position, in this case, since the rib 44 has the inertia to maintain its static state, it will rotate in the opposite direction relative to the clutch sleeve 41 at the beginning of the rotation of the clutch sleeve 41, and then abut against the forward-rotating roller 43 located in the forward-rotating cooperative position and drive the forward-rotating roller 43 to move from the forward-rotating cooperative position to the forward-rotating separation position. The forward-rotating roller 43 and the clutch sleeve 41 are in a non-contact or movably connected state, and the clutch sleeve 41 cannot drive the forward-rotating roller 43, the rib 44 and the turntable 42 to rotate synchronously but are in an idling state. That is to say, the rib 44 is used to ensure that the forward-rotating roller 43 will not be in the forward-rotating cooperative position when the second rotating wheel 30 rotates as the driving wheel, and to ensure that the second rotating wheel 30 cannot be transmitted to the first rotating wheel 20 regardless of whether it rotates in the clockwise direction M1 or the counterclockwise direction M2.
[0058] Those skilled in the art will appreciate that the depth of the unlocking groove 422 is not greater than the depth of the forward-rotating groove 421 at the coordinated position, so that the rib 44 can smoothly move from the unlocking groove 422 to the forward-rotating groove 421 .
[0059] In another embodiment of the present application, please refer to Figures 4 to 7 The rotating disk 42 is provided with a reversal groove 423 on its outer surface, the reversal groove 423 extends in the circumferential direction and has a reversal separation position and a reversal cooperation position, the groove depth of the reversal groove 423 is gradually reduced from the reversal separation position to the reversal cooperation position, and the direction from the shallow groove of the reversal groove 423 to the deep groove of the reversal groove 423 is the counterclockwise direction M2; the clutch assembly 40 also includes a reversal roller 45, and the reversal roller 45 is located in the reversal groove 423; when the first rotating wheel 20 acts as a driving wheel and rotates in the counterclockwise direction M2, it drives the rotating disk 42 to rotate, and moves the reversal roller 45 from the reversal separation position to the reversal cooperation position, so that the rotating disk 42, the reversal roller 45 and the clutch sleeve 41 are in an engaged state and drive the clutch sleeve 41 to rotate, and when the second rotating wheel 30 acts as a driving wheel and rotates in the counterclockwise direction M2, it drives the clutch sleeve 41 to rotate, and moves the reversal roller 45 from the reversal cooperation position to the reversal separation position, so that the reversal roller 45 and the clutch sleeve 41 are separated from each other.
[0060] When the first rotating wheel 20 rotates in the counterclockwise direction M2 as the driving wheel, the turntable 42 is connected to the first rotating wheel 20 and rotates therewith, and the reversing roller 45 located in the reversing groove 423 remains in the original position under the action of inertia until the two sides of the reversing roller 45 are abutted by the turntable 42 and the clutch sleeve 41 (moves relative to the turntable 42 and moves from the reversing separation position to the reversing coordination position). At this time, the turntable 42, the reversing roller 45 and the clutch sleeve 41 are in an engaged state, the reversing roller 45 and the clutch sleeve 41 rotate with the turntable 42, and the clutch sleeve 41 is connected to the second rotating wheel 30 so that the second rotating wheel 30 also rotates therewith.
[0061] In combination with the foregoing, the coordinated arrangement of the forward-rotating roller 43 and the forward-rotating groove 421 enables the first rotating wheel 20 as the driving wheel to drive the second rotating wheel 30 to rotate when rotating in the clockwise direction M1, and the coordinated arrangement of the reverse-rotating roller 45 and the reverse-rotating groove 423 enables the first rotating wheel 20 to drive the second rotating wheel 30 to rotate when rotating in the counterclockwise direction M2. That is, in this solution, the first rotating wheel 20 can drive the second rotating wheel 30 to rotate regardless of whether it rotates clockwise or counterclockwise.
[0062] In another embodiment of the present application, please refer to Figures 4 to 7 The unlocking groove 422 is also connected to the reversing groove 423; when the second rotating wheel 30 acts as a driving wheel and rotates in the clockwise direction M1, it drives the clutch sleeve 41 to rotate, and the rib 44 rotates in the opposite direction relative to the clutch sleeve 41 under the action of its inertia, so that the reversing roller 45 located in the reversing cooperation position moves to the reversing separation position, so that the reversing roller 45 and the clutch sleeve 41 are separated from each other.
[0063] Based on the analysis basically the same as above, the rib 44 is used to ensure that the reversing roller 45 will not be in the reversing coordination position when the second wheel 30 rotates as the driving wheel, and ensure that the second wheel 30 cannot transmit to the first wheel 20 regardless of whether it rotates in the clockwise direction M1 or the counterclockwise direction M2.
[0064] In combination with the above, the rib 44 cooperates with the unlocking groove 422, and the unlocking groove 422 is connected with the clockwise groove 421 and the reverse groove 423, so that the second rotating wheel 30 cannot drive the first rotating wheel 20 to rotate regardless of whether it rotates clockwise or counterclockwise.
[0065] Those skilled in the art may also provide two sets of ribs 44, one set acting on the forward roller 43 and the other acting on the reverse roller 45, instead of the design of a single set of ribs 44 in this solution that can act on both the forward roller 43 and the reverse roller 45. Compared with the former, this solution has a simple structure and saves the space required.
[0066] In another embodiment of the present application, please refer to Figure 4 or Figure 7 The forward groove 421 and the reverse groove 423 are symmetrically arranged on both sides of the unlocking groove 422. In the illustrated structure, the forward roller 43 and the reverse roller 45 have the same structure, and the difference lies in the different positions. The symmetrical arrangement of the forward groove 421 and the reverse groove 423 ensures that the rotation effect of the first rotating wheel 20 rotating in the clockwise direction M1 or in the counterclockwise direction M2 to transmit the torque to the second rotating wheel 30 will not be different due to different directions.
[0067] In another embodiment of the present application, please refer to Figure 4 and Figure 5 There are multiple forward-rotating grooves 421 and they are arranged at intervals, there are multiple forward-rotating rollers 43, and any forward-rotating roller 43 is placed in a forward-rotating groove 421; there are multiple unlocking grooves 422 and ribs 44, and any unlocking groove 422 is connected to a forward-rotating groove 421 and accommodates a rib 44.
[0068] Under this design, when the first rotating wheel 20 rotates in the clockwise direction M1, the clutch sleeve 41 is simultaneously acted upon by the force F of multiple clockwise rollers 43, thereby increasing the instantaneous friction force of the relative movement between the clutch sleeve 41 and the clockwise rollers 43 to shorten the delay time of the linkage between the first rotating wheel 20 and the second rotating wheel 30.
[0069] Similarly, there are multiple reversal grooves 423 and reversal rollers 45, so that when the first rotating wheel 20 rotates in the counterclockwise direction M2, the clutch sleeve 41 is simultaneously acted upon by the forces of multiple reversal rollers 45, thereby increasing the instantaneous friction force of the relative movement between the clutch sleeve 41 and the reversal rollers 45 to shorten the delay time of the linkage between the first rotating wheel 20 and the second rotating wheel 30.
[0070] In the illustrated structure, there are three forward rotation grooves 421, three reverse rotation grooves 423 and three unlocking grooves 422. Correspondingly, there are three forward rotation rollers 43, three reverse rotation rollers 45 and three ribs 44.
[0071] In another embodiment of the present application, please refer to Figure 4 and Figure 5 , the forward grooves 421 are arranged at equal intervals. This design enables the clutch sleeve 41 to receive multiple forces F from the forward roller 43 on the X-axis and Y-axis to offset each other when the first rotating wheel 20 rotates in the clockwise direction M1, thereby facilitating the improvement of the noise caused by the shaking of the transmission. Similarly, the reverse grooves 423 are arranged at equal intervals, which is conducive to improving the noise when the first rotating wheel 20 rotates in the counterclockwise direction M2.
[0072] In this embodiment, the forward-rotating roller 43 and the reverse-rotating roller 45 are both cylindrical. In other embodiments, the roller may be spherical, or have a columnar structure with a cross section of a Reuleaux triangle.
[0073] In this embodiment, the first rotating wheel 20 and the second rotating wheel 30 are both gear structures. That is, the circumference of the first rotating wheel 20 and the second rotating wheel 30 are provided with a plurality of uniformly arranged gear teeth to mesh with the gears matched therewith to realize transmission. Persons skilled in the art can set the pitch, module, etc. of the gear teeth according to actual needs, and can also set them to spur gears, helical gears or bevel gears according to actual needs, which are not limited here.
[0074] In another embodiment of the present application, the clutch shaft 10 is connected to the first rotating wheel 20 and rotates synchronously, the rotating disk 42 is connected to the clutch shaft 10 and rotates synchronously, and the second rotating wheel 30 is movably connected to the clutch shaft 10. The upper and lower ends of the clutch shaft 10 are fixed by bearings 50. In the illustrated structure, the second rotating wheel 30 is located between the first rotating wheel 20 and the clutch sleeve 41, the second rotating wheel 30 is connected to the clutch sleeve 41, and the first clutch shaft 10 is connected to the first rotating wheel 20 and the rotating disk 42 at the same time, so as to realize the synchronous rotation of the rotating disk 42 and the first rotating wheel 20. This arrangement enables the first rotating wheel 20 and the rotating disk 42 to be arranged at intervals to realize synchronous rotation, and each structure is compactly arranged without interference. Those skilled in the art can adjust the positions between the first rotating wheel 20, the second rotating wheel 30 and the clutch assembly 40 according to actual needs, and no unique limitation is made here.
[0075] In another embodiment of the present application, please refer to Figure 2 and Figure 8 The clutch assembly 40 further includes a connecting plate 46 for connecting the ribs 44, and the connecting plate 46 is sleeved on the clutch shaft 10 and movably connected to the clutch shaft 10. The setting of the connecting plate 46 enables the ribs 44 to be connected to form a whole, so that the ribs 44 can rotate synchronously.
[0076] In another embodiment of the present application, the clutch assembly 40 further includes a blocking member 47 for applying static friction to the rib 44. As can be seen from the above analysis, when the clutch sleeve 41 rotates, the rib 44 does not move under inertia but contacts the forward roller 43 or the reverse roller 45 and pushes it from the cooperative position to the separated position. In other words, the realization of this function of the rib 44 mainly depends on the ability of the rib 44 not to move, which is achieved through its own inertia. This ability can also be enhanced by increasing the restriction on the rib 44 to increase its static friction.
[0077] The blocking member 47 and the connecting plate 46 may be fixedly connected, and the static friction force generated by the abutment between the blocking member 47 and the external structure becomes the static friction force of the rib 44. The blocking member 47 may also be fixedly connected to the external structure and abut against the connecting plate 46, and the static friction force generated by the abutment between the blocking member 47 and the connecting plate 46 becomes the static friction force of the rib 44.
[0078] In another embodiment of the present application, please refer to Figure 2 and Figure 8 The connecting plate 46 is provided with an installation groove 461 for installing the blocking member 47. The blocking member 47 is sleeved in the installation groove 461 and connected to the connecting plate 46 (it can be fixedly connected or matched). The blocking member 47 abuts against the external structure. The static friction between the blocking member 47 and the external structure becomes the resistance to the movement of the rib 44. In this embodiment, the blocking member 47 is a rubber ring, and the blocking member 47 can be replaced after being worn.
[0079] Embodiment 2
[0080] like Figures 1 to 10 As shown, this embodiment provides a control box, including two input shafts (a first input shaft and a second input shaft) and an output shaft 104 , and the input shaft and the output shaft 104 are connected via a clutch structure 101 .
[0081] The specific structure of the clutch structure 101 is shown in Example 1. The first input shaft is connected to the first rotating wheel 20 to drive the first rotating wheel 20 to rotate; the second input shaft is connected to the second rotating wheel 30 to drive the second rotating wheel 30 to rotate; the second rotating wheel 30 is connected to the output shaft 104; the output shaft 104 outputs the control operation by forward and reverse rotation.
[0082] Combined with the design of the clutch structure 101, the first input shaft rotates to drive the first rotating wheel 20 to rotate, and drives the second rotating wheel 30 and the output shaft 104 to rotate via the clutch assembly 40. The second input shaft rotates to drive the second rotating wheel 30 and the output shaft 104 to rotate, and at this time, the rotation of the second rotating wheel 30 will not be transmitted to the first rotating wheel 20 and the first input shaft.
[0083] In the illustrated embodiment, the first input shaft is connected to the driving motor 103, and the second output shaft 104 is connected to the operating panel 102 for manual operation.
[0084] The driving motor 103 provides a first torque to the first input shaft. The first input shaft rotates under the first torque to drive the first rotating wheel 20 to rotate. The first rotating wheel 20 rotates and drives the second rotating wheel 30 and the output shaft 104 to rotate under the action of the clutch assembly 40. Therefore, the driving motor 103 can drive the output shaft 104 to rotate.
[0085] The operator rotates the operating disk 102 to provide the second torque to the second input shaft. The second input shaft rotates under the action of the second torque to drive the second rotating wheel 30 and the output shaft 104 to rotate. At this time, due to the one-way transmission of the first rotating wheel 20 and the second rotating wheel 30, the first rotating wheel 20 is not affected by the rotation of the second rotating wheel 30 and remains stationary. In other words, when the operator uses the operating disk 102 to control the rotation, it will not affect the drive motor 103.
[0086] In the illustrated embodiment, transmission is achieved between the driving motor 103 and the first rotating wheel 20 , and between the operating panel 102 and the second rotating wheel 30 via a connecting shaft and a gear pair 105 .
[0087] In this embodiment, the drive motor 103 and the operating panel 102 are used as two independent torque input modes. The drive motor 103 is used for daily operation. When the drive motor 103 is replaced or repaired or during on-site emergency operation, the output shaft 104 can be rotated by manually operating the operating panel 102. It should be noted that the drive motor 103 and the operating panel 102 cannot operate at the same time. The drive motor 103 is electrically connected to the automatic control system to realize automatic control, and the setting of the operating panel 102 facilitates on-site control.
[0088] Of course, those skilled in the art may also use other devices or structures to provide the first torque / second torque for the first input shaft / second input shaft, such as two independent motors or two independent operating panels, which is not limited here.
[0089] Since the control box provided in this embodiment adopts all the technical solutions of the first embodiment, it also has all the technical effects brought by the above embodiments, which will not be described one by one here.
[0090] The control box of this embodiment can be applied to a circuit breaker. In this case, the output shaft 104 is linked with the tripping member of the circuit breaker. The output shaft 104 rotates, thereby rotating the tripping member. The tripping member has a connected state for connecting the circuit and a disconnected state for disconnecting the circuit. The tripping member controls the circuit to switch between the connected state and the disconnected state by rotating forward and reverse directions.
[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
