Description

Technical Field

[0001] The present invention belongs to the field of mechanical transmission, and particularly 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. A gear set connects the motor and the output shaft and is used to convert the torque of the motor into the torque of the output shaft. In actual applications, there is a need to add a way to input the torque of the output shaft, such as manually driving the output shaft to rotate. This is to replace the motor drive with manual drive in case of motor failure, on-site emergency operation, or maintenance. At this time, since the output shaft and the motor are meshed and connected by a 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 achieved. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a clutch structure and a control box, which aim to solve the one-way transmission between two structural members.

There are multiple first grooves which are arranged at intervals, there are multiple rolling members which are correspondingly arranged in any one of the first grooves, and there are multiple rib bodies which are correspondingly arranged in any one of the second grooves.

[0012] Further, the first grooves are arranged at equal intervals, and the second grooves are arranged at equal intervals.

[0013] Further, the first groove, the second groove and the third groove are arranged in sequence in the clockwise direction and are provided in a matching manner. There are multiple first grooves which are arranged at equal intervals;

[0014] There are multiple rib bodies which are correspondingly arranged in the second groove.

[0015] Further, an annular accommodation groove is formed inwards on the peripheral side of the disc rack. The clutch assembly further includes a seal, and the seal is placed in the accommodation groove and its outer surface abuts against the rolling member.

[0019] An output shaft that outputs control operations by forward rotation and reverse rotation;

[0020] A clutch structure, which is the clutch structure as described above, and the second runner is connected to the output shaft;

[0021] A first input shaft that is connected to the first runner to drive the first runner to rotate;

[0022] A second input shaft that is connected to the second runner to drive the second runner to rotate.

[0023] The clutch structure provided by the present invention enables the first rotating wheel to drive the second rotating wheel to rotate synchronously when the first rotating wheel rotates from the first groove to the second groove, while the second rotating wheel cannot drive the first rotating wheel to rotate synchronously when the second rotating wheel rotates from the second groove to the first groove.

[0042] Embodiment 1

[0043] Please refer to Figures 1 to 9 , this embodiment provides a clutch structure, including a first runner 10, a second runner 20 and a clutch assembly 30. The first runner 10 and the second runner 20 are independently arranged and achieve one-way transmission through the clutch assembly 30.

[0044] The first runner 10 has a rotating shaft, and a cylindrical clutch cavity 11 is centrally provided in the first runner 10.

[0045] The second runner 20 is coaxially arranged with the first runner 10, including the case where the first runner 10 is sleeved on the second runner 20, and the cases where the first runner 10 is above the second runner 20 or the second runner 20 is above the first runner 10. In the illustrated embodiment, the clutch structure further includes a fixed shaft 40, and both the first runner 10 and the second runner 20 are sleeved on the fixed shaft 40. The fixed shaft 40 is used to define the movement of the first runner 10 and the second runner 20 in the horizontal and vertical directions. Both the first runner 10 and the second runner 20 are movably connected to the fixed shaft 40. The second runner 20 is located above the first runner 10, and the second runner 20 is connected to the rib 32 through a connecting plate 35. Preferably, the rib 32 and the connecting plate 35 are integrally provided for convenient assembly. In other embodiments, the first runner 10 is fixedly connected to the fixed shaft 40 or the second runner 20 is fixedly connected to the fixed shaft 40. When the first runner 10 is sleeved on the second runner 20, the second runner 20 is fixedly connected to the fixed shaft 40 to transmit the torque of the second runner 20 via the fixed shaft 40.

[0046] The clutch assembly 30 includes a disc frame 31, rolling elements 33 and ribs 32. The disc frame 31 is placed in the clutch cavity 11 and can rotate around the rotation axis. The disc frame 31 has a first groove 311 and a second groove 312 that communicate with each other opened inward on its outer surface. The depth of the first groove 311 is greater than that of the second groove 312. The first groove 311 and the clutch cavity 11 form a moving channel for accommodating and rolling the rolling elements 33. The moving channel is tapered in the direction of the second groove 312 and has a cooperative position capable of clamping the rolling elements 33 and a separated position capable of movably connecting with the rolling elements 33. The rib 32 is located between the second groove 312 and the clutch cavity 11;

[0047] Wherein, the rib 32 is connected to the second runner 20. When the first runner 10 rotates from the first groove 311 towards the second groove 312, the rolling elements 33 are driven to move to the cooperative position. When the second runner 20 rotates towards the first groove 311 together with the rib 32, the rolling elements 33 are moved to the separated position.

[0048] The transmission process between the first runner 10 and the second runner 20 is as follows:

[0049] Please refer to Figure 7 and Figure 8, when the first runner 10 rotates as a driving wheel from the first groove 311 towards the second groove 312, the rolling member 33 moves forward in the direction of rotation under the frictional force of the first runner 10 (for ease of description, the front in the direction of rotation is simply referred to as the front). When the rolling member 33 rolls to the cooperative position, the rolling member 33 is clamped by the bottom of the first groove 311 and the cavity wall of the clutch cavity 11, so that the rolling member 33, the disc holder 31 and the first runner 10 rotate synchronously. The rolling member 33, the disc holder 31 and the first runner 10 rotate synchronously, causing the rib 32 to also rotate synchronously, thereby causing the second runner 20 to rotate.

[0050] Please refer to Figure 7 and Figure 9 , when the second runner 20 rotates as a driving wheel from the second groove 312 towards the first groove 311, the rib 32 rotates accordingly. The rib 32 abuts against the rolling member 33 and pushes the rolling member 33 forward. The rolling member 33 moves from the cooperative position to the separation position. At this time, the rolling member 33 is movably connected to the cavity wall of the clutch cavity 11 or has a gap, that is to say, the rolling member 33 is not clamped by the cavity wall of the clutch cavity 11 and the disc holder 31 and is in a free rotation state. The rib 32 drives the rolling member 33 and the disc holder 31 to rotate idly in the clutch cavity 11. Therefore, the first runner 10 cannot obtain the torque from the second runner 20.

[0051] As described above, the setting of the clutch assembly 30 enables the first runner 10 to drive the second runner 20 to rotate synchronously when rotating from the first groove 311 towards the second groove 312, while the second runner 20 cannot drive the first runner 10 to rotate synchronously when rotating from the second groove 312 towards the first groove 311. Those skilled in the art can set the relative positions of the first groove 311 and the second groove 312 to achieve linkage and idling in different directions. For example, if the second groove 312 is in front of the first groove 311 in the clockwise direction, then when the first runner rotates clockwise, it can drive the second runner 20 to rotate. When the second runner 20 rotates counterclockwise, the second runner 20 cannot transmit to the first runner 10. On the contrary, if the second groove 312 is in front of the first groove 311 in the counterclockwise direction, then when the first runner rotates counterclockwise, it can drive the second runner 20 to rotate. When the second runner 20 rotates clockwise, the second runner 20 cannot transmit to the first runner 10.

[0052] Please refer to Figure 6 and Figure 7, when the disk rack 31 has a third groove 313 and a fourth groove 314, the structures of the third groove 313 and the fourth groove 314 are respectively the same as those of the first groove 311 and the second groove 312. The difference is that the first groove 311 is located behind the second groove 312 in the clockwise direction, and the third groove 313 is located in front of the fourth groove 314 in the clockwise direction. The first groove 311, the second groove 312, the third groove 313, and the fourth groove 314 are all opened on the outer peripheral side of the disk rack 31. At this time, a rolling member 33 is correspondingly provided for any one of the first groove 311 and the third groove 313, and a rib 32 is correspondingly provided for any one of the second groove 312 and the fourth groove 314.

[0053] When the first runner 10 rotates clockwise as the driving wheel, the rolling member 33 located in the first groove 311 moves forward clockwise under the frictional force of the first runner 10. When the rolling member 33 rolls to the cooperative position, the rolling member 33 is clamped by the bottom of the first groove 311 and the wall of the clutch cavity 11, so that the rolling member 33, the disk rack 31, and the first runner 10 rotate synchronously. The rolling member 33, the disk rack 31, and the first runner 10 rotate synchronously, causing the rib 32 to rotate synchronously, thereby causing the second runner 20 to rotate. At this time, regardless of whether the rolling member 33 located in the third groove 313 is in the cooperative position or the separated position, it does not affect the transmission of the first runner 10. When the first runner 10 rotates counterclockwise as the driving wheel, the rolling member 33 located in the third groove 313 moves forward clockwise under the frictional force of the first runner 10. When the rolling member 33 rolls to the cooperative position, the rolling member 33 is clamped by the bottom of the third groove 313 and the wall of the clutch cavity 11, so that the rolling member 33, the disk rack 31, and the first runner 10 rotate synchronously. The rolling member 33, the disk rack 31, and the first runner 10 rotate synchronously, causing the rib 32 to rotate synchronously, thereby causing the second runner 20 to rotate.

[0054] When the second runner 20 rotates clockwise as the driving wheel, the rib 32 rotates accordingly. The rib 32 abuts against the rolling element 33 located in the first groove 311 and moves the rolling element 33 forward from the cooperative position to the separated position. At this time, the rolling element 33 is in a free rotation state. It should be noted that at this time, if the rolling element 33 located in the third groove 313 is in the separated position, the rib 32, the rolling element 33 and the disc frame 31 rotate idly in the clutch cavity 11. When the rolling element 33 located in the third groove 313 is in the cooperative position, it will also move from the cooperative position to the separated position under the frictional force of the first runner 10 and the third groove 313, and the effect of the rib 32, the rolling element 33 and the disc frame 31 rotating idly in the clutch cavity 11 can also be achieved. Similarly, when the second runner 20 rotates counterclockwise as the driving wheel, the rib 32 rotates accordingly. The rib 32 abuts against the rolling element 33 located in the third groove 313 and moves the rolling element 33 forward from the cooperative position to the separated position. At this time, the rolling element 33 is in a free rotation state, and the rib 32 drives the rolling element 33 and the disc frame 31 to rotate idly in the clutch cavity 11.

[0055] Preferably, the second groove 312 and the fourth groove 314 have the same structure. One rib 32 is located in both the second groove 312 and the fourth groove 314 at the same time, that is, the rib 32 can rotate clockwise to act on the rolling element 33 in the first groove 311, and can act on the rolling element 33 in the third groove 313 when rotating counterclockwise. At this time, the first groove 311 and the third groove 313 are symmetrically arranged on both sides of the second groove 312 / the fourth groove 314.

[0056] In the illustrated embodiment, the first groove 311, the second groove 312 and the third groove 313 are arranged in sequence in the clockwise direction and are provided in a matching manner. There are a plurality of first grooves 311 which are arranged at intervals. Correspondingly, there are a plurality of second grooves 312 which are arranged at intervals. There are a plurality of third grooves 313 which are arranged at intervals; there are a plurality of ribs 32 which are correspondingly arranged in the second grooves 312. There are a plurality of rolling elements 33, and any one of the rolling elements 33 is correspondingly arranged in the first groove 311 and the third groove 313. Under this design, when the first runner 10 rotates, it is simultaneously subjected to a plurality of acting forces (simultaneously acted by a plurality of rolling elements 33), so as to increase the instantaneous frictional force of relative movement to shorten the delay time of the linkage between the first runner 10 and the second runner 20. Preferably, the first grooves 311 are arranged at equal intervals. Correspondingly, the second grooves 312 are arranged at equal intervals. The third grooves 313 / the fourth grooves 314 are arranged at equal intervals. This design makes the force on the first runner 10 balanced during transmission, which is beneficial to improving the noise caused by the shaking during transmission.

[0057] In the illustrated embodiment, there are three ribs 32 which are arranged at equal intervals. There are six rolling elements 33 which are all arranged on both sides of the rib 32. Those skilled in the art can also select other quantities according to actual needs, such as the rib 32 being four, five, six, etc.

[0058] Please refer to Figure 4 , the moving channel is tapered in the direction of the second groove 312, and the angle formed by the bottom of the first groove 311 and the rotation direction at this point is 12 degrees. In other embodiments, those skilled in the art can set this angle to 10 degrees, 13 degrees, 15 degrees, etc. according to actual needs, and this is not limited to a unique value here.

[0059] It should be noted that in the illustrated embodiment, the rolling member 33 is cylindrical. In other embodiments, the rolling member 33 can be spherical, or a columnar structure with a cross-section of a Reuleaux triangle.

[0060] Please refer to Figure 3 , the second runner 20 is connected to the rib body 32 through a connecting plate 35. The connecting plate 35 is provided with a plurality of convex teeth 351 on the surface connected to the second runner 20, and the second runner 20 is provided with grooves on the surface connected to the connecting plate 35 that cooperate with the convex teeth 351. Through the connection of the convex teeth 351 and the grooves, a larger abutting area is provided between the second runner 20 and the connecting plate 35, and the grooves can effectively limit the circumferential movement of the convex teeth 351, that is, limit the relative movement between the second runner 20 and the connecting plate 35, so as to avoid slipping between the second runner 20 and the connecting plate 35. Preferably, the connecting plate 35 and the rib body 32 are integrally provided for convenient assembly. Those skilled in the art can also integrally provide the connecting plate 35 and the second runner 20. This is not limited to a unique value here.

[0061] Please refer to Figure 3 and Figure 5 , the clutch assembly 30 further includes a seal 34. The disk holder 31 is provided with an annular receiving groove 315 on its circumferential side inwardly, and the seal 34 is placed in the receiving groove 315 and its outer surface abuts against the rolling member 33. The seal 34 is made of rubber material, and the rolling member 33 is made of metal material. The seal 34 abuts against the rolling member 33 to increase the friction force of the rolling member 33 rotating relative to the seal 34, effectively avoiding the situation where the rolling member 33 slips when the first runner 10 drives the rolling member 33 to move, thereby helping to improve the stability of the transmission.

[0062] In this embodiment, both the first runner 10 and the second runner 20 are gear structures. That is, both the circumferential sides of the first runner 10 and the second runner 20 have a plurality of uniformly arranged teeth to achieve transmission by meshing with the gears that cooperate with them. Those skilled in the art can set the pitch, modulus, etc. of the teeth according to actual needs, and can also be set as spur gears, helical gears or bevel gears according to actual needs, and this is not limited here.

[0071] In this embodiment, the driving motor 60 and the operation panel 70 are used as two independent torque input methods. The driving motor 60 is used for daily operations. When replacing or overhauling the driving motor 60 or for on-site emergency control, the output shaft 50 can be rotated by manually operating the operation panel 70. It should be noted that the driving motor 60 and the operation panel 70 cannot operate simultaneously. The driving motor 60 is electrically connected to the automatic control system to achieve automatic control, and the setting of the operation panel 70 facilitates on-site control.

[0072] Of course, those skilled in the art can also use other devices or structures to provide the first torque / second torque to the first input shaft / second input shaft, such as two independent motors or two independent operation boards. This is not the only limitation herein.
