[0028] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0029] The transmission device of the external slip monitoring component in the embodiment of the present utility model includes: a number-of-turns counting component 3, a poking rod component 4, an input component 1 and an output component 2. The input component 1 is in contact with the output component 2, and the input component 1 rotates to drive the output component 2 to rotate;

[0030] The number-of-turns counting component 3 is arranged on the input component 1, and the poking rod component 4 is arranged on the output component 2.

[0031] Wherein, when the output component 2 and the output component 2 rotate relative to each other, the poking rod component 4 impacts the monitoring end of the number-of-turns counting component 3.

[0032] The transmission device of the external slip monitoring component in the embodiment of the present utility model is convenient for monitoring the slip condition of the friction plate and improving the maintenance efficiency.

[0033] Specifically, as Figures 1 to 4 shown, the transmission device is any one of the existing torque limiters, clutches or brakes. The output component 2 is connected to the poking rod component 4, and the input component 1 is connected to the number-of-turns counting component 3. When the input torque exceeds the maximum range that the transmission device can withstand, the two sets of friction plates for transmitting power in the transmission device rotate relative to each other, that is, the housing 11 and the hub 21 rotate relative to each other. Furthermore, the number-of-turns counting component 3 and the poking rod component 4 rotate relative to each other. During the rotation process, the monitoring end of the number-of-turns counting component 3 and the poking rod component 4 will collide, so that the number-of-turns counting component 3 can record the number of turns of the relative rotation of the housing 11 and the hub 21 and monitor the slip condition of the two sets of friction plates.

[0034] The transmission device according to the embodiment of the present utility model is provided with a revolution counting component 3 and a lever component 4. The revolution counting component 3 is arranged on the input component 1, and the lever component 4 is arranged on the output component 2. Then, the two friction plates for transmitting power of the transmission device rotate relatively, the revolution counting component 3 and the lever component 4 rotate relatively, and the monitoring end of the revolution counting component 3 collides with the lever component 4. Thus, it is convenient for the revolution counting component 3 to record the number of revolutions of the relative rotation of the housing 11 and the hub 21, and monitor the slipping condition of the two friction plates. Therefore, it is not necessary to disassemble the rotating device to check the slipping condition of the friction plates, improving the maintenance efficiency.

[0035] In some embodiments, the output component 2 includes a hub 21 and a first friction plate 22 sleeved on and connected to the hub 21, and the input component 1 includes a housing 11 and a second friction plate 12 connected to the housing 11.

[0036] The first friction plate 22 is in contact with the second friction plate 12. The revolution counting component 3 is arranged on the housing 11, and the lever component 4 is arranged on the hub 21.

[0037] Specifically, as Figures 1 to 4 shown, the first friction plate 22 is in contact with the second friction plate 12 to transmit power. Thus, it is convenient for the input component 1 to transmit the power to the output component 2. When the input torque exceeds the maximum range that the transmission device can bear, slipping occurs between the first friction plate 22 and the second friction plate 12 to limit the output torque from exceeding the maximum range that the transmission device can bear, avoiding excessive output torque of the transmission device. Then, the housing 11 and the hub 21 rotate relatively. At this time, the revolution counting component 3 and the lever component 4 rotate. For example, every time the housing 11 and the hub 21 rotate relatively by one revolution, the revolution counting component 3 and the lever component 4 collide once, and at this time, the revolution counting component 3 records one revolution.

[0038] The transmission device according to the embodiment of the present utility model is provided with a revolution counting component 3 and a lever component 4. The revolution counting component 3 is arranged on the housing 11, and the lever component 4 is arranged on the hub 21. Then, the two friction plates for transmitting power of the transmission device rotate relatively, and then the housing 11 and the hub 21 rotate relatively. At this time, the revolution counting component 3 and the lever component 4 rotate, resulting in the relative rotation of the revolution counting component 3 and the lever component 4, and the monitoring end of the revolution counting component 3 collides with the lever component 4. Thus, it is convenient for the revolution counting component 3 to record the number of revolutions of the relative rotation of the housing 11 and the hub 21, and monitor the slipping condition of the two friction plates. Therefore, it is not necessary to disassemble the rotating device to check the slipping condition of the friction plates, improving the maintenance efficiency.

[0039] Meanwhile, the turn counting component 3 is arranged outside the housing 11 , which facilitates replacement and maintenance of the turn counting component 3 , while also avoiding oil corrosion inside the housing 11 , thereby improving the stability of the turn counting component 3 in use.

[0040] In some embodiments, the turn counting component 3 includes a counting member 31 and a paddle 32 . The counting member 31 is detachably mounted on the housing 11 , and a monitoring end of the turn counting member 31 is pivotally connected to the paddle 32 .

[0041] Specifically, Figures 1 to 4 As shown, the monitoring end of the counting member 31 is pivotally connected to the paddle 32, and the paddle 32 extends in a direction close to the lever member 4. The lap counting member 3 can be an existing counter, for example, a paddle 32 type counter. Furthermore, the lap counting member 3 adopts an existing mechanical counter to improve the stability and safety of the lap counter when in use.

[0042] In some embodiments, the lever component 4 includes a lever 41, which is detachably mounted on the wheel hub 21, and the position of the lever 41 on the wheel hub 21 corresponds to the position of the counting component on the housing 11.

[0043] When the output component 2 rotates relative to the output component 2 , the shifting rod 41 impacts the shifting piece 32 of the revolution counting component 3 .

[0044] Specifically, Figures 1 to 4 As shown, the lever 41 is detachably mounted on the wheel hub 21, and the position of the lever 41 on the wheel hub 21 corresponds to the position of the counting component on the housing 11, that is, when the wheel hub 21 and the housing 11 rotate relative to each other, the lever 41 hits the paddle 32, thereby completing the counting of the number of relative rotations of the wheel hub 21 and the housing 11.

[0045] In some embodiments, the end surface of the lever 41 facing or away from the paddle 32 is an arc surface 42. When the lever 41 impacts the paddle 32, the lever 41 impacts the paddle 32. By providing the arc surface 42, the paddle 32 can be guided when the lever 41 impacts the paddle 32, so as to reduce the impact force between the lever 41 and the paddle 32 and improve the service life of the lever 41 and the paddle 32.

[0046] In some embodiments, the size of the lever 41 in the circumferential direction of the hub 21 gradually decreases in the direction away from the hub 21. This reduces the weight of the lever 41 and reduces the cost. At the same time, the center of gravity of the lever 41 is set farther away from the rotation center of the hub 21, which reduces the centrifugal force of the lever 41 when the hub 21 rotates and improves the stability of the lever 41 when in use.

[0047] In some embodiments, the paddle 32 includes a connecting piece 321 and an impact piece 322. One end of the connecting piece 321 is pivotally connected to the monitoring end of the counting member 31, the other end of the connecting piece 321 is connected to the impact piece 322, and the shape of the impact piece 322 is spherical, circular or semi-circular. The impact piece 322 is set to be spherical, circular or semi-circular, which can reduce the contact area between the impact piece 322 and the shift lever 41 during impact, reduce the impact force, and improve the service life of the impact piece 322. Further, the impact piece 322 and the connecting piece 321 are integrally formed to improve the structural strength of the paddle 32, and thus improve the service life of the paddle 32.

[0048] In some embodiments, the number of the turns counting components 3 and the shift lever components 4 is multiple, and the multiple turns counting components 3 correspond to the multiple shift lever components 4 one by one, so as to avoid misjudgment by the operator due to problems in the measurement results of a single turns counting member 31, and improve the stability and safety of the monitoring of the slipping situation. Further, the turns counting component 3 is detachably connected to the housing 11, which is convenient for replacing or repairing the turns counting component 3 and improves the convenience of maintenance.

[0049] The transmission system of the embodiment of the present utility model includes a driving component; a transmission device, where the transmission device is the transmission device of the external slipping monitoring component in any one of the above, and one end of the transmission device is connected to the driving component;

[0050] a speed reducer, and the speed reducer is connected to the other end of the transmission device.

[0051] Specifically, as Figures 1 to 4 shown, the transmission device is arranged between the driving component and the accelerator to limit the torque output by the driving component, so as to prevent the speed reducer or other components of the transmission system from being damaged due to overload.

[0052] The transmission system of the embodiment of the present utility model can monitor the slipping situation of the first friction plate 22 and the second friction plate 12 of the transmission device by arranging the turns counting component 3 and the shift lever component 4. Furthermore, it is not necessary to disassemble the rotating device to check the slipping situation of the friction plate, thus improving the maintenance efficiency.

[0053] In some embodiments, the transmission device is any one of a torque limiter, a clutch or a brake.

[0054] By installing the number-of-turns counting components 3 and the lever components 4 on the housings 11 and the hubs 21 of the friction torque limiter, the clutch, and the brake respectively, and regularly observing the values of the counters, it is possible to clearly determine whether the friction torque limiter, the clutch, and the brake have experienced overload slipping. Regularly observing the values of the counters can determine the usage conditions of the friction torque limiter, the clutch, and the brake, facilitating regular maintenance and replacement by the customer, and helping the customer effectively avoid economic losses and safety problems caused by the failure of the friction torque limiter, the clutch, and the brake. By counting the number of slips, it is possible to verify whether the actual service life of the friction torque limiter, the clutch, and the brake is consistent with the theoretically calculated life, providing data support for subsequent product R & D calculations.
