Description

Technical Field

[0001] The utility model relates to the field of mechanical transmission devices, and particularly relates to a transmission device and a transmission system. Background Art

[0002] The friction torque limiter transmits a set torque value through the cooperation of an elastic component and a friction component. When the impact torque encountered by the equipment is greater than the torque setting value of the friction torque limiter, the friction component in the friction torque limiter will slip, preventing the equipment from being damaged. Without disassembly, it is impossible to determine whether the friction plates at the input end and output end of the friction torque limiter, clutch, and brake have experienced overload slipping, and thus impossible to determine whether the friction torque limiter, clutch, and brake can protect the entire transmission chain. At the same time, the number of friction slips of the friction torque limiter, clutch, and brake cannot be counted, and the service life of the friction torque limiter, clutch, and brake calculated theoretically during R & D design cannot be verified. When the user fails to replace or maintain them regularly, it may cause damage to the entire transmission chain, resulting in huge economic losses and other safety problems.

[0003] In the related art, when commissioning or troubleshooting is required, it is often necessary to disconnect the commissioning device or faulty device from the transmission device and then disassemble the friction torque limiter to check the slipping condition of the friction plate.

[0027] 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.

[0028] The transmission device in the embodiment of the present utility model includes a revolution counting component 3, an output component 1 and an input component 2. The input component 2 includes an input shaft 21 and a first friction plate 22 sleeved on the input shaft 21 and connected to the input shaft 21. The output component 1 includes a housing 11 and a second friction plate 12 connected to the housing 11. The first friction plate 22 and the second friction plate 12 are in contact with each other. The first friction plate 22 is sleeved with an external gear 23. The first gear 33 and the external gear 23 are meshed with each other. The revolution counting component 3 is connected to the housing 11. The monitoring end of the revolution counting component 3 is provided with the first gear 33. The first friction plate 22 is sleeved with an external gear 23. The first gear 33 and the external gear 23 are meshed with each other so that the external gear 23 drives the first gear 33 to rotate.

[0029] Specifically, as Figures 1 to 3 shown, the transmission device is any one of a friction torque limiter, a clutch or a brake. One end of the input component 2 is connected to a driving motor. For example, one end of the input shaft 21 is connected to the driving motor. The first friction plate 22 and the second friction plate 12 are in contact with each other to transmit power, thereby driving the housing 11 to rotate. The other end of the housing 11 is connected to an output shaft to drive the output shaft to rotate, or the other end of the housing 11 is directly connected to a speed reducer to output power.

[0030] When the input torque exceeds the maximum range that the transmission device can withstand, 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 withstand, and to prevent the torque output by the transmission device from being too large.

[0031] At this time, rotation occurs between the housing 11 and the first friction plate 22. Further, the first friction plate 22 rotates relative to the housing 11. Since the outer gear 23 is provided on the outer peripheral surface of the first friction plate 22 and meshes with the first gear 33, the rotation of the outer gear 23 drives the rotation of the first gear 33 to monitor the slipping condition between the first friction plate 22 and the second friction plate 12.

[0032] After the outer gear 23 drives the first gear 33 to rotate, the monitoring end of the revolution counting component 3 monitors the slipping condition by monitoring the number of revolutions of the first gear 33. Further, there is no need to disassemble the transmission device for inspection. At the same time, the monitoring end of the revolution counting component 3 is arranged inside the housing 11 to prevent damage to the revolution counting component 3 caused by the collision of external objects.

[0033] In the transmission device of the embodiment of the present utility model, the outer gear 23 provided on the friction plate meshes with the first gear 33 of the revolution counting component 3. When relative rotation occurs between the first friction plate 22 and the housing 11, the rotation of the outer gear 23 drives the rotation of the first gear 33, thereby facilitating the monitoring of the slipping condition between the first friction plate 22 and the second friction plate 12, that is, facilitating the monitoring of the slipping condition between the first friction plate 22 and the housing 11. There is no need to disassemble the transmission device to check the slipping condition of the first friction plate 22 and the second friction plate 12, improving the maintenance efficiency. And the revolution counting component 3 is arranged inside the housing 11 to prevent the collision of external objects with the revolution counting component 3 during the operation of the device, resulting in damage to the revolution counting component 3, and improving the stability of the use of the revolution counting component 3.

[0034] In some embodiments, the revolution counting component 3 further includes a revolution counting member 31 arranged on the housing 11, a second gear 35, and a torque pin 34 arranged on the housing 11. The torque pin 34 is sleeved with a rotatable first gear 33.

[0035] The monitoring shaft 32 of the revolution counting member 31 is sleeved with the second gear 35, and the second gear 35 meshes with the first gear 33.

[0036] Specifically, as Figures 1 to 3 shown, the first gear 33 is arranged on the existing torque pin 34, and the revolution counting member 31 is arranged on the housing 11, thereby facilitating the indirect monitoring of the rotation of the first gear 33 through the rotation of the second gear 35, and facilitating the indirect monitoring of the rotation of the outer gear 23 through the rotation of the first gear 33, and further monitoring the slipping condition between the first friction plate 22 and the second friction plate 12.

[0037] When slipping occurs between the first friction plate 22 and the second friction plate 12, the second gear 35 sleeved on the monitoring shaft 32 rotates, and further the monitoring shaft 32 rotates, and the rotation between the first friction plate 22 and the second friction plate 12 is indirectly monitored through the rotation of the monitoring shaft 32.

[0038] By setting the first gear 33 on the torque pin 34, the number-of-turns counting member 31 and the friction plate do not come into direct contact, thus avoiding the impact of slight vibrations during operation of the friction plate on the monitoring shaft 32 of the number-of-turns counting member 31 and improving the operating stability of the number-of-turns counting member 31.

[0039] Furthermore, the number of the first friction plates 22 and the second friction plates 12 is multiple, and the multiple first friction plates 22 and the second friction plates 12 are alternately arranged in the width direction of the input shaft 21. And the multiple first friction plates 22 are in contact with the multiple first friction plates 22 to transmit power.

[0040] In some embodiments, the first gear 33 includes a gear body 331 and a bearing 332. The bearing 332 is sleeved on the torque pin 34, and the gear body 331 is arranged on the bearing 332.

[0041] By providing the bearing 332, friction between the first gear 33 and the torque pin 34 can be avoided, and the operating stability and safety of the first gear 33 can be improved.

[0042] In some embodiments, the number of the number-of-turns counting members 31 and the number of the first gears 33 are multiple, and the multiple number-of-turns counting members 31 and the multiple first gears 33 correspond to each other one by one.

[0043] Specifically, as Figures 1 to 3 shown, the number of the number-of-turns counting members 31 and the number of the first gears 33 are multiple. A plurality of first gears 33 are provided on the torque pin 34 so as to mesh with the multiple number-of-turns counting members 31 one by one, so as to avoid misjudgment by the operator due to problems in the measurement results of a single number-of-turns counting member 31 and improve the stability and safety of monitoring the slipping condition. Further, the number-of-turns counting member 3 is detachably connected to the housing 11, which is convenient for replacing or repairing the number-of-turns counter and improves the convenience of maintenance.

[0044] In some embodiments, the number-of-turns counting member 31 is a rotary counter. The rotary counter can adopt a mechanical structure, such as a gear mechanism. These structures are relatively simple and stable, are not easily interfered by the external environment, and thus have high reliability and durability of the mechanical structure. The rotary counter usually has a long service life and can withstand long-term use and frequent counting operations.

[0045] Furthermore, the rotary counter can adopt a digital direct reading display mode, and the user can directly read the current count value without performing complex calculations or conversions. The rotary counter is designed with a zero reset device, and the user can reset the counter to zero through a simple operation, which is convenient for the next counting.

[0046] In some embodiments, the size of the first gear 33 in the extending direction of the input shaft 21 is larger than that of the second gear 35 in the extending direction of the input shaft 21. That is, the size of the first gear 33 in the left-right direction is larger than that of the second gear 35 in the left-right direction. During the use of the transmission device, the first gear 33 is thus prevented from moving away from the second gear 35 along the extending direction of the input shaft 21 during use, improving the stability of the first gear 33 and the second gear 35 during use.

[0047] In some embodiments, the size of the outer gear 23 of the second friction plate 12 in the extending direction of the input shaft 21 is larger than that of the first gear 33 in the extending direction of the input shaft 21. That is, the size of the outer gear 23 of the second friction plate 12 in the left-right direction is larger than that of the first gear 33 in the left-right direction. During the use of the transmission device, the outer gear 23 of the second friction plate 12 is thus prevented from moving away from the first gear 33 along the extending direction of the input shaft 21 during use, improving the stability of the outer gear 23 of the second friction plate 12 and the first gear 33 during use.

[0048] The transmission system of the embodiment of the present utility model includes a driving component, a speed reducer, and a transmission device. The transmission device is the above-mentioned transmission device. One end of the transmission device is connected to the driving component, and the speed reducer is connected to the other end of the transmission device.

[0049] Specifically, as Figures 1 to 3 shown, the transmission device is arranged between the driving component and the accelerator to limit the torque output by the driving component, preventing the speed reducer or other components of the transmission system from being damaged due to overload.

[0050] The transmission system of the embodiment of the present utility model can monitor the slipping conditions of the first friction plate and the second friction plate of the transmission device by providing a rotation count component and a lever component. Thus, it is not necessary to disassemble the rotating device to check the slipping conditions of the friction plates, improving the maintenance efficiency.

[0051] Furthermore, the transmission device is any one of a torque limiter, a clutch, or a brake.

[0052] By installing gears and rotary counters on the torque pins 34 of the friction torque limiter, clutch, and brake, and regularly observing the values of the counters, it is possible to clearly determine whether the friction torque limiter, clutch, and brake have experienced overload slipping. Regularly observing the values of the counters can also determine the usage conditions of the friction torque limiter, clutch, and brake, facilitating customers' regular maintenance and replacement, and helping customers effectively avoid economic losses and safety problems caused by the failure of the friction torque limiter, clutch, and brake. By counting the number of slips, it is possible to verify whether the actual service life of the friction torque limiter, clutch, and brake is consistent with the theoretically calculated life, providing data support for subsequent product R & D calculations.
