[0002] Currently, most mechanical structure operation adjustment and control, such as soft start, overload protection of motors and various functional devices, overload slippage of shaft rotation, and power transmission between two shafts, use a mechanical clutch transmission mechanism between the two shafts. Traditional mechanical clutch transmission mechanisms can cause motor overload, overheating and burnout or gearbox gear breakage due to overload and stall at the output end during use.

[0003] Therefore, it is necessary to invent a mechanical clutch transmission mechanism to prevent output overload in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical clutch transmission mechanism that prevents output overload, so as to solve the problems mentioned in the background art.

[0006] The clutch main shaft includes a base, a shaft body integrally formed at the top center of the base, a flat shaft integrally formed at the top center of the shaft body, a round shaft integrally formed at the top of the flat shaft, and an annular mounting groove circumferentially formed at the top of the outer side wall of the round shaft.

[0007] The output transmission wheel includes a transmission wheel body, and a connecting groove is provided through the center of the top of the transmission wheel body. Multiple mounting holes are provided at the edge of the top opening of the connecting groove in a ring array.

[0008] The overload protection component includes a connecting locking plate assembly, a graphite gasket is fitted to the top of the connecting locking plate assembly, a secondary clutch plate assembly is fitted to the top of the graphite gasket, a primary clutch plate assembly is fitted to the top of the secondary clutch plate assembly, a return spring is fixedly mounted to the top of the primary clutch plate assembly, a bearing is fixedly mounted to the top of the return spring, a retaining circlip is fitted to the top of the bearing, and the retaining circlip is adapted to an annular mounting groove. The bearing is snapped onto the top of the round shaft by the retaining circlip and the annular mounting groove.

[0009] Preferably, a magnet is installed inside the mounting hole, the connecting groove is adapted to the shaft, and the inner sidewall of the connecting groove is in close contact with the outer sidewall of the shaft.

[0010] Preferably, the connecting clip assembly includes an annular piece, and baffles are integrally formed on both sides of the top of the annular piece, and the baffles are vertically arranged.

[0011] Preferably, the outer wall of the annular piece is integrally formed with a limiting piece corresponding to a plurality of mounting holes, and the limiting piece is fastened to the inside of the mounting hole.

[0012] Preferably, the clutch assembly includes a clutch body, on which a first arc-shaped limiting piece is integrally formed symmetrically, and the outer side of the first arc-shaped limiting piece extends to the outer side of the clutch body.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention utilizes an overload protection component. The overload protection component rotates via the clutch spindle, and is limited by a first and second arc-shaped limiting plate, causing the output drive wheel to rotate. When the output drive wheel is obstructed, the bearing, return spring, and main clutch assembly continue to rotate. Because the first arc-shaped limiting plate is blocked by a baffle plate, the clutch assembly stops rotating, while the main clutch assembly continues to rotate, driven by the clutch spindle. The second arc-shaped limiting plate is misaligned with the first arc-shaped limiting plate. When the second arc-shaped limiting plate overlaps with the first arc-shaped limiting plate again, it again limits the rotation, continuing to drive the output drive wheel. Therefore, even when the output drive wheel stalls or the output end is overloaded, the power source output end can continue to rotate while the clutch slips, thus protecting the motor and gearbox from damage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-8 The mechanical clutch transmission mechanism for preventing output overload shown includes a power source 1. A clutch main shaft 2 is fixedly installed at the output end of the power source 1. An output transmission wheel 3 and an overload prevention component 4 are sleeved and installed on the clutch main shaft 2, and the output transmission wheel 3 is located at the bottom of the overload prevention component 4. The clutch main shaft 2 includes a base 201. A shaft body 202 is integrally formed at the top center of the base 201. A flat shaft 203 is integrally formed at the top center of the shaft body 202. A round shaft 204 is integrally formed at the top of the flat shaft 203. An annular mounting groove 205 is formed around the top of the outer side wall of the round shaft 204.

[0027] Furthermore, the output transmission wheel 3 includes a transmission wheel body 301. A connecting groove 302 is provided through the center of the top of the transmission wheel body 301. Multiple mounting holes 303 arranged in a ring array are provided at the edge of the top opening of the connecting groove 302. A magnet 304 is installed inside the mounting hole 303. The magnet 304 is an induction magnet for controlling the external circuit, which will not be described in this case. The connecting groove 302 is adapted to the shaft 202, and the inner sidewall of the connecting groove 302 is in close contact with the outer sidewall of the shaft 202.

[0028] The overload protection component 4 includes a connecting locking plate assembly 401. A graphite gasket 407 is fitted to the top of the connecting locking plate assembly 401. A slave clutch plate assembly 402 is fitted to the top of the graphite gasket 407. A master clutch plate assembly 403 is fitted to the top of the slave clutch plate assembly 402. The outer diameters of the slave clutch plate assembly 402 and the master clutch plate assembly 403 are the same, and the outer sides of both the slave clutch plate assembly 402 and the master clutch plate assembly 403 are located inside the baffle plate 4012. A return spring 404 is fixedly mounted on the top of the master clutch plate assembly 403. The return spring 404 provides thrust to ensure that the master clutch plate assembly 403, the slave clutch plate assembly 402, the connecting locking plate assembly 401, and the graphite gasket 407 are tightly fitted, so that the first arc-shaped limiting plate 4023 and... When the second arc-shaped limiting piece 4033 can overlap again, they fit together. The top of the return spring 404 is fixedly provided with a bearing 405. The top of the bearing 405 is fitted with a retaining ring 406, and the retaining ring 406 is adapted to the annular mounting groove 205. The bearing 405 is snapped onto the top of the round shaft 204 through the retaining ring 406 and the annular mounting groove 205. The connecting locking piece assembly 401 includes an annular piece 4011. Both sides of the top of the annular piece 4011 are integrally formed with baffles 4012, and the baffles 4012 are vertically arranged. The baffles 4012 are used to block the first arc-shaped limiting piece 4023. The outer wall of the annular piece 4011 is integrally formed with limiting pieces 4013 corresponding to the multiple mounting holes 303, and the limiting pieces 4013 are snapped into the inside of the mounting holes 303.

[0029] The clutch assembly 402 includes a clutch body 4021. A first arc-shaped limiting piece 4023 is integrally formed symmetrically on the clutch body 4021, extending outwards from the outer side of the first arc-shaped limiting piece 4023 to the outer side of the clutch body 4021. The outer side of the first arc-shaped limiting piece 4023 needs to exceed the baffle 4012. A circular groove 4022 is formed through the middle of the clutch body 4021, and the circular groove 4022 is adapted to the shaft 202. The main clutch plate assembly 403 includes a main clutch plate body 4031. A square groove 4032 is formed through the middle of the main clutch plate body 4031, and the square groove 4032 is adapted to the flat shaft 203. A second arc-shaped limiting plate 4033 is integrally formed symmetrically on the main clutch plate body 4031, and the second arc-shaped limiting plate 4033 is adapted to the first arc-shaped limiting plate 4023. The outer side of the second arc-shaped limiting plate 4033 is adjacent to the outer side of the main clutch plate body 4031. The sidewalls are flush. Through the overload protection component 4, the clutch main shaft 2 drives the overload protection component 4 to rotate. The overload protection component 4, through the first arc-shaped limiting plate 4023 and the second arc-shaped limiting plate 4033, drives the output transmission wheel 3 to rotate. When the output transmission wheel 3 is obstructed, the bearing 405, the return spring 404, and the main clutch assembly 403 continue to rotate. Because the first arc-shaped limiting plate 4023 is blocked by the baffle plate 4012, the clutch assembly 402 stops rotating. When the clutch plate assembly 403 continues to rotate, it is driven by the clutch main shaft 2. The second arc-shaped limit plate 4033 is misaligned with the first arc-shaped limit plate 4023. When the second arc-shaped limit plate 4033 and the first arc-shaped limit plate 4023 overlap again, they are limited again, and the output transmission wheel 3 continues to rotate. Thus, even if the output transmission wheel 3 is stalled or the output end is overloaded, the output end of the power source 1 can continue to rotate and the clutch slips, thereby protecting the motor and gearbox from damage.

[0030] Working principle of this utility model:

[0031] In use, power source 1 provides power to drive the clutch main shaft 2 to rotate. The clutch main shaft 2 drives the main clutch plate assembly 403 to rotate, which has a limiting effect with the first arc-shaped limiting plate 4023 and the second arc-shaped limiting plate 4033. This allows the clutch plate assembly 402, the connecting locking plate assembly 401, and the output transmission wheel 3 to rotate. When the output transmission wheel 3 stops rotating due to obstruction, the clutch main shaft 2 continues to drive the main clutch plate assembly 403 to rotate. Because the first arc-shaped limiting plate 4023 is blocked by the baffle plate 4012, and the circular groove 4022 is adapted to the shaft body 202, the clutch plate assembly 402 can be stopped from rotating. The square slot 4032 is adapted to the flat shaft 203, and the main clutch assembly 403 receives a certain torque, which causes the first arc-shaped limiting plate 4023 and the second arc-shaped limiting plate 4033 to disengage. After the main clutch assembly 403 rotates 180°, the first arc-shaped limiting plate 4023 and the second arc-shaped limiting plate 4033 overlap again. Due to the pushing action of the return spring 404, the first arc-shaped limiting plate 4023 and the second arc-shaped limiting plate 4033 are again limited and fitted, so that the output transmission wheel 3 can continue to rotate. If the output transmission wheel 3 is resisted again, it will continue the previous step until the output transmission wheel 3 is subjected to normal working torque.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
