Example one

Referring to fig. 1 to 8, the present embodiment provides a clutch structure 101, which includes 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.

The clutch shaft 10 defines the movement of the first pulley 20, the second pulley 30 and the clutch assembly 40 in the horizontal direction, and further, the central axis of the clutch shaft 10 is the rotation axis of the first pulley 20, the second pulley 30 and the clutch assembly 40.

The clutch assembly 40 includes a clutch sleeve 41, a rotary disk 42 and a clockwise rolling member 43, the clutch sleeve 41 is connected with the second rotating wheel 30, the clutch sleeve 41 is sleeved on the clutch shaft 10 and is arranged at an interval with the clutch shaft 10 to form a clutch cavity, the rotary disk 42 is connected with the first rotating wheel 20, the rotary disk 42 is sleeved on the clutch shaft 10 and is positioned in the clutch cavity, the rotary disk 42 is provided with a clockwise groove 421 in the outer surface thereof, the clockwise groove 421 extends along the circumferential direction and has a clockwise separation position and a clockwise rotation cooperation position, the groove depth of the clockwise groove 421 is gradually reduced from the clockwise separation position to the clockwise rotation cooperation position, and the clockwise rolling member 43 is positioned in the clockwise groove 421.

The direction from the shallow groove of the clockwise groove 421 to the deep groove of the clockwise groove 421 is the clockwise direction M1.

When the first rotating wheel 20 is used as a driving wheel and rotates in the clockwise direction M1, the rotating disc 42 is driven to rotate, and the clockwise rolling element 43 moves from the clockwise rotation separation position to the clockwise rotation cooperation position, so that the rotating disc 42, the clockwise rolling element 43 and the clutch sleeve 41 are in the engagement state and the clutch sleeve 41 is driven to rotate, when the second rotating wheel 30 is used as a driving wheel and rotates in the clockwise direction M1, the clutch sleeve 41 is driven to rotate, and the clockwise rolling element 43 moves from the clockwise rotation cooperation position to the clockwise rotation separation position, so that the clockwise rolling element 43 and the clutch sleeve 41 are separated from each other.

The following transmission process between the first and second wheels 20 and 30 is as follows:

referring to fig. 4 and 5, when first wheel 20 serves as a driving wheel and rotates in clockwise direction M1, rotating disc 42 rotates along with first wheel 20, clockwise rolling element 43 located in clockwise groove 421 remains at the original position under the inertia until both sides of clockwise rolling element 43 are abutted by rotating disc 42 and clutch sleeve 41 (move from the clockwise separation position to the clockwise cooperation position relative to rotating disc 42), at this time, clockwise rolling element 43 is clamped by rotating disc 42 and clutch sleeve 41 to make clockwise rolling element 43, rotating disc 42 and clutch sleeve 41 in the engagement state, clockwise rolling element 43 and clutch sleeve 41 rotate along with rotating disc 42, and clutch sleeve 41 is connected with second wheel 30 to make second wheel 30 rotate along with second wheel 30.

Referring to fig. 4 and 6, when second roller 30 serves as a driving wheel and rotates in clockwise direction M1, clutch sleeve 41 rotates along with second roller 30, and if clockwise roller 43 is in the clockwise rotation cooperating position, clockwise roller 43 is moved to the clockwise rotation disengaging position by the traction force generated by the friction of clutch sleeve 41, so that clockwise roller 43 and clutch sleeve 41 are disengaged from each other. Clutch sleeve 41 is free-wheeling relative to 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.

From the above analysis, the clutch assembly 40 is configured such that the first wheel 20 can drive the second wheel 30 to rotate synchronously when rotating in the clockwise direction M1 as the driving wheel, and the second wheel 30 can not drive the first wheel 20 to rotate synchronously when rotating in the clockwise direction M1 as the driving wheel. The relative positions of the forward rotation groove 421 and the reverse rotation groove 423 can be set by those skilled in the art to realize linkage and idle rotation in different directions. For example, the reverse groove 423 is located clockwise forward of the clockwise groove 421, when the first wheel 20 rotates counterclockwise, the second wheel 30 can be driven to rotate, and the second wheel 30 cannot be transmitted to the first wheel 20. On the contrary, the reverse rotation groove 423 is located in the counterclockwise front of the forward rotation groove 421, so that the clockwise rotation of the first wheel 20 can drive the second wheel 30 to rotate, and the second wheel 30 cannot be transmitted to the first wheel 20.

In another embodiment of the present application, the turntable 42 is provided with an unlocking groove 422 inward on the outer surface thereof, and the unlocking groove 422 is communicated with the clockwise rotation groove 421 and is located on the shallow side of the clockwise rotation groove 421; the clutch assembly 40 further includes a rib block 44, the rib block 44 being located in the unlocking recess 422; when the second rotating wheel 30 is used as a driving wheel and rotates in the counterclockwise direction M2, the clutch sleeve 41 is driven to rotate, and the rib 44 rotates reversely relative to the clutch sleeve 41 under the inertia effect thereof to move the clockwise rolling member 43 located at the clockwise cooperating position to the clockwise separating position, so that the clockwise rolling member 43 and the clutch sleeve 41 are separated from each other.

When second rotor 30 is acting as a driving wheel and in counterclockwise direction M2, if clockwise roller 43 is in the clockwise disengaged position, clutch sleeve 41 cannot transmit the torque of second rotor 30 to turntable 42 without any problem. If clockwise-rotation roller 43 is located at the clockwise-rotation cooperative position, in this case, since rib block 44 has inertia to maintain its stationary state and rotates in the opposite direction with respect to clutch sleeve 41 at the beginning of rotation of clutch sleeve 41, and further abut against the clockwise rotation roller 43 located at the clockwise rotation cooperating position and drive the clockwise rotation roller 43 to move from the clockwise rotation cooperating position to the clockwise rotation disengaging position, the clockwise rotation roller 43 and the clutch sleeve 41 are in a non-contact state or a state of being capable of being movably connected, the clutch sleeve 41 cannot drive the clockwise rotation roller 43, the rib block 44 and the rotating disc 42 to synchronously rotate and be in an idle rotation state, that is, the rib block 44 is used for ensuring that the clockwise rotation roller 43 cannot be in the clockwise rotation cooperating position when the second rotating wheel 30 rotates as a driving wheel, while ensuring that no rotation of the second wheel 30, either in the clockwise direction M1 or the counter-clockwise direction M2, is transmitted to the first wheel 20.

It will be appreciated by those skilled in the art that the groove depth of the unlocking groove 422 is not greater than the groove depth of the clockwise groove 421 at the cooperating position. So that the rib 44 can smoothly move from the unlocking groove 422 to the clockwise groove 421.

In another embodiment of the present application, referring to fig. 4 to 7, the rotary plate 42 is provided with a reverse groove 423 inward on an outer surface thereof, the reverse groove 423 extends along a circumferential direction and has a reverse separation position and a reverse cooperation position, a groove depth of the reverse groove 423 is tapered from the reverse separation position to the reverse cooperation position, and a direction from a shallow groove of the reverse groove 423 to a deep groove of the reverse groove 423 is a counterclockwise direction M2; the clutch assembly 40 further comprises a reverse rolling member 45, and the reverse rolling member 45 is positioned in the reverse groove 423; when the first rotating wheel 20 is used as a driving wheel and rotates in the counterclockwise direction M2, the rotating disc 42 is driven to rotate, and the reverse rolling member 45 is moved from the reverse separation position to the reverse cooperation position, so that the rotating disc 42, the reverse rolling member 45 and the clutch sleeve 41 are in the engagement state to drive the clutch sleeve 41 to rotate, when the second rotating wheel 30 is used as a driving wheel and rotates in the counterclockwise direction M2, the clutch sleeve 41 is driven to rotate, and the reverse rolling member 45 is moved from the reverse cooperation position to the reverse separation position, so that the reverse rolling member 45 and the clutch sleeve 41 are separated from each other.

When the first pulley 20 rotates in the counterclockwise direction M2 as the drive pulley, the rotation disc 42 is connected to the first pulley 20 and rotates therewith, the reverse rolling member 45 located in the reverse groove 423 is retained at the original position by inertia until both sides of the reverse rolling member 45 are abutted by the rotation disc 42 and the clutch sleeve 41 (moved from the reverse separation position to the reverse cooperation position by moving relative to the rotation disc 42), at this time, the rotation disc 42, the reverse rolling member 45 and the clutch sleeve 41 are in the engagement state, the reverse rolling member 45 and the clutch sleeve 41 rotate with the rotation disc 42, and the clutch sleeve 41 is connected to the second pulley 30 to rotate the second pulley 30 therewith.

In combination with the above, the clockwise rotation roller 43 and the clockwise rotation groove 421 are cooperatively disposed, so that the first rotating wheel 20 as a driving wheel can drive the second rotating wheel 30 to rotate when rotating in the clockwise direction M1, and the counter-rotation roller 45 and the counter-rotation groove 423 are cooperatively disposed, so that the first rotating wheel 20 can drive the second rotating wheel 30 to rotate when rotating in the counterclockwise direction M2. That is, in the present embodiment, the first rotor 20 can rotate the second rotor 30 regardless of the clockwise or counterclockwise rotation.

In another embodiment of the present application, referring to fig. 4 to 7, the unlocking groove 422 is further communicated with the reverse groove 423; when the second rotating wheel 30 is used as a driving wheel and rotates in the clockwise direction M1, the clutch sleeve 41 is driven to rotate, and the rib 44 rotates reversely relative to the clutch sleeve 41 under the inertia effect thereof to move the reverse rolling member 45 located at the reverse cooperation position to the reverse separation position, so that the reverse rolling member 45 and the clutch sleeve 41 are separated from each other.

Based on substantially the same analysis as previously described, rib block 44 serves to ensure that when second wheel 30 is rotating as a drive wheel, reverse roller 45 is not in the reverse cooperative position, and that neither rotation of second wheel 30 in clockwise direction M1 nor counterclockwise direction M2 is transmitted to first wheel 20.

In combination with the above, the rib 44 and the unlocking groove 422 are matched, and in combination with the arrangement that the unlocking groove 422 is communicated with the clockwise rotation groove 421 and the counter-rotation groove 423, the obtained second rotating wheel 30 cannot drive the first rotating wheel 20 to rotate no matter clockwise or anticlockwise.

One skilled in the art could also provide two sets of rib blocks 44, one set acting on the forward rolling member 43 and the other set acting on the reverse rolling member 45, and instead of the design in which a single set of rib blocks 44 could act on both the forward rolling member 43 and the reverse rolling member 45. Compared with the former, the scheme simplifies the structure and saves the space required to be occupied.

In another embodiment of the present application, referring to fig. 4 or fig. 7, the forward rotation groove 421 and the reverse rotation groove 423 are symmetrically disposed on two sides of the unlocking groove 422. In the illustrated structure, the forward roller 43 and the reverse roller 45 are identical in structure, and are different in position. The symmetrical arrangement of the clockwise rotation groove 421 and the counter-rotation groove 423 allows the first wheel 20 to rotate in the clockwise direction M1 or in the counterclockwise direction M2 without a difference in the rotational effect of transmitting the torque to the second wheel 30.

In another embodiment of the present application, please refer to fig. 4 and 5, a plurality of forward rotation grooves 421 are arranged at intervals, a plurality of forward rotation rollers 43 are provided, and any one of the forward rotation rollers 43 is disposed in one of the forward rotation grooves 421; the unlocking groove 422 and the rib block 44 are provided in plurality, and any unlocking groove 422 is communicated with a clockwise groove 421 and accommodates a rib block 44.

With this arrangement, when the first rotating wheel 20 rotates in the clockwise direction M1, the clutch sleeve 41 is simultaneously acted by the acting forces F of the plurality of clockwise rolling members 43, so as to increase the instantaneous friction force of the relative movement of the clutch sleeve 41 and the clockwise rolling members 43 to shorten the delay time of the linkage of the first rotating wheel 20 and the second rotating wheel 30.

Similarly, the reverse groove 423 and the reverse rolling member 45 are plural, so that when the first rotating wheel 20 rotates in the counterclockwise direction M2, the clutch sleeve 41 is simultaneously acted by the acting forces of the plural reverse rolling members 45, thereby increasing the instantaneous friction force of the relative movement of the clutch sleeve 41 and the reverse rolling member 45 to shorten the delay time of the coupling of the first rotating wheel 20 and the second rotating wheel 30.

In the illustrated structure, there are three forward rotation grooves 421, reverse rotation grooves 423, and unlocking grooves 422. Correspondingly, the forward rolling piece 43, the reverse rolling piece 45 and the rib block 44 are all three.

In another embodiment of the present application, referring to fig. 4 and 5, the clockwise rotation grooves 421 are disposed at equal intervals, and the design is such that when the first rotating wheel 20 rotates in the clockwise direction M1, the component forces of the multiple acting forces F from the clockwise rotation roller 43 on the clutch sleeve 41 on the X axis and the Y axis cancel each other out, thereby being beneficial to improving the noise caused by the transmission shaking. Similarly, the reverse grooves 423 are equally spaced, which is beneficial for improving the noise when the first rotating wheel 20 rotates in the counterclockwise direction M2.

In this embodiment, both the forward rolling member 43 and the reverse rolling member 45 have a cylindrical shape. In other embodiments, the rollers may be spherical or cylindrical structures having a reuleaux triangle cross-section.

In the present embodiment, the first runner 20 and the second runner 30 are both of a gear structure. That is, the peripheral sides of the first and second rotors 20 and 30 each have a plurality of uniformly arranged gear teeth for meshing with the mating gears to realize transmission. The pitch, module, etc. of the gear teeth can be set by those skilled in the art according to actual needs, and can also be set as a straight gear, a helical gear or a bevel gear according to actual needs, which is not limited herein.

In another embodiment of the present application, clutch shaft 10 is coupled to and rotates synchronously with first rotor 20, disc 42 is coupled to and rotates synchronously with clutch shaft 10, and second rotor 30 is movably coupled to clutch shaft 10. The upper and lower ends of the clutch shaft 10 are fixed by bearings 50. In the structure shown in the figure, the second rotating wheel 30 is positioned between the first rotating wheel 20 and the clutch sleeve 41, the second rotating wheel 30 is connected with the clutch sleeve 41, the first clutch shaft 10 is simultaneously connected with the first rotating wheel 20 and the rotating disc 42, the synchronous rotation of the rotating disc 42 and the first rotating wheel 20 is realized, the arrangement enables the first rotating wheel 20 and the rotating disc 42 to be arranged at intervals to realize synchronous rotation, and the structures are compactly arranged without interference. The position between the first rotating wheel 20, the second rotating wheel 30 and the clutch assembly 40 can be adjusted by those skilled in the art according to actual needs, and is not limited herein.

In another embodiment of the present application, referring to fig. 2 and 8, the clutch assembly 40 further includes a connecting plate 46 for connecting each rib 44, wherein the connecting plate 46 is sleeved on the clutch shaft 10 and movably connected to the clutch shaft 10. The connecting plate 46 is arranged so that the rib blocks 44 are connected to form a whole, and synchronous rotation of the rib blocks 44 is realized.

In another embodiment of the present application, the clutch assembly 40 further includes a retarding member 47 for applying a static friction force to the rib block 44. As can be seen from the above analysis, when the clutch sleeve 41 rotates, the rib 44 is not moved by inertia and abuts against the forward rolling member 43 or the reverse rolling member 45 to push it away from the cooperating position to the disengaged position. That is, the performance of this function by the rib block 44 relies primarily on the ability of the rib block 44 to not move, which is achieved by its own inertia. This ability can also be added by increasing the restriction on the rib block 44 to increase its static friction.

The blocking member 47 and the connecting plate 46 may be fixedly connected, and a static friction force generated by the abutment of the blocking member 47 with the external structure becomes a static friction force of the rib block 44. The blocking member 47 may be fixedly connected to the external structure and may abut against the connecting plate 46, and a static friction force generated by the abutment between the blocking member 47 and the connecting plate 46 may be a static friction force of the rib 44.

In another embodiment of the present application, referring to fig. 2 and 8, the connecting plate 46 is provided with a mounting groove 461 for mounting the blocking member 47, and the blocking member 47 is sleeved in the mounting groove 461 and connected (fixed or matched) with the connecting plate 46. The blocking member 47 abuts the external structure. The static friction of the blocking member 47 with the external structure acts as a resistance to the movement of the rib block 44. In this embodiment, the blocking member 47 is a rubber ring, and the blocking member 47 is replaced after the blocking member 47 is worn.

Example two

As shown in fig. 1 to 10, the present embodiment provides a control box, which includes 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 by a clutch structure 101.

Please refer to the first embodiment for a specific structure of the clutch structure 101.

In conjunction with the design of the clutch mechanism 101, the first input shaft rotates to rotate the first rotor 20, and drives the second rotor 30 and the output shaft 104 to rotate via the clutch assembly 40. The rotation of the second input shaft rotates the second rotor 30 and the output shaft 104, and the rotation of the second rotor 30 is not transmitted to the first rotor 20 and the first input shaft.

In the illustrated embodiment, the first input shaft is connected to a driving motor 103, and the second output shaft 104 is connected to an operation panel 102 for manual operation.

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 wheel 20 to rotate, and the first wheel 20 rotates to drive the second wheel 30 and the output shaft 104 to rotate under the action of the clutch assembly 40. Thus, the driving motor 103 may drive the output shaft 104 to rotate.

The operator rotates the operation panel 102 to provide a second torque to the second input shaft, and the second input shaft rotates under the second torque to drive the second turning wheel 30 and the output shaft 104 to rotate, at this time, due to the unidirectional transmission of the first turning wheel 20 and the second turning wheel 30, the first turning wheel 20 is not affected by the rotation of the second turning wheel 30 and remains stationary. That is, the operator does not affect the drive motor 103 when performing rotation control using the operation panel 102.

In the illustrated embodiment, the driving motor 103 and the first runner 20, and the operating panel 102 and the second runner 30 are driven by a connecting shaft and a gear pair 105.

In this embodiment, the driving motor 103 and the operation panel 102 are used as two independent torque input modes, the driving motor 103 is used for daily work, and the output shaft 104 can be rotated by manually operating the operation panel 102 when the driving motor 103 is replaced or repaired or during emergency operation in the field. It should be noted that the drive motor 103 and the operation panel 102 cannot operate simultaneously. The driving motor 103 is electrically connected with an automatic control system to realize automatic control, and the operation panel 102 is arranged to facilitate field control.

Of course, other devices or structures may be used by those skilled in the art to provide the first/second torque to the first/second input shafts, such as two independent motors or two independent operation panels, and are not limited herein.

Since the control box provided in this embodiment adopts all technical solutions of the first embodiment, all technical effects brought by the above embodiments are also achieved, and are not described herein again.

The control box of this embodiment is applicable in the circuit breaker, and at this moment, output shaft 104 and the tripping member linkage of circuit breaker, output shaft 104 rotate to make the tripping member rotate.
