Description

Technical Field

[0001] This invention relates to the field of magnetic powder clutch technology, specifically to a magnetic powder clutch with anti-leakage function. Background Technology

[0002] A magnetic powder clutch is a device that transmits torque based on electromagnetic induction and magnetic powder. It is widely used in printing presses, laminating machines, slitting machines, and cable winding machines. The outer side of its drive shaft is connected to the clutch body through bearings, which requires lubrication with lubricating oil. However, there is a probability that the lubricating oil will leak, which will pollute the environment if it leaks onto the ground. In view of this, traditional devices are not perfect and do not have the function of preventing lubricating oil from leaking onto the ground, which is quite troublesome. A magnetic powder clutch with a leakage prevention function is needed.

[0003] The existing magnetic powder clutches have the following drawbacks:

[0004] 1. Patent document CN216555055U discloses a dual-shaft magnetic powder clutch, "including a magnetic powder clutch, with several heat sinks at both the left and right ends of the magnetic powder clutch; an output shaft at the middle of the right end of the magnetic powder clutch; an input shaft at the middle of the left end of the magnetic powder clutch; conductive plates on the output shaft; a fixing block at the bottom end of the magnetic powder clutch; a conductive rod at the middle of the fixing block; a limit block at the left end of the conductive rod; a stop block at the right end of the conductive rod; a spring between the stop block and the fixing block; a wire at the left end of the limit block; the fixing block and the magnetic powder clutch are connected by bolts; the stop block and the conductive rod are fixedly connected; the limit block and the conductive rod are connected by threads; the spring and the fixing block are fixedly connected; and the right end of the conductive rod is spherical." Traditional devices are not perfect and lack the function to prevent lubricating oil from leaking onto the ground, which easily leads to environmental pollution.

[0005] 2. Patent document: CN115750618A, a magnetic powder clutch with a control system, "including a magnetic powder clutch, a rotating shaft rotatably connected in the middle of the magnetic powder clutch, heat dissipation blades fixed on the outer surface of the rotating shaft, a barrier mechanism and a heat conduction mechanism provided on the outer surface of the magnetic powder clutch; heat dissipation fins are fixedly connected to both ends of the magnetic powder clutch, and the heat conduction mechanism is fixedly connected to the back of the heat dissipation fins; the barrier mechanism includes a connecting sleeve, the connecting sleeve is fitted on the outer surface of the magnetic powder clutch, a spiral plate is fixedly connected to the inner wall of the connecting sleeve, and heat dissipation holes are opened on the surface of the connecting sleeve. This invention, by setting a connecting sleeve on the outer surface of the magnetic powder clutch, allows the air force generated by the heat dissipation blades to enter the interior of the connecting sleeve through the connecting sleeve, resulting in a larger contact area with the surface of the magnetic powder clutch. This allows the air force to come into contact with the surface of the magnetic powder clutch and then be discharged from the heat dissipation holes, ensuring better heat dissipation of the magnetic powder clutch and possessing strong practicality." Traditional devices are not perfect, lacking facilities for conveniently adding lubricating oil for lubrication, increasing labor consumption.

[0006] 3. Traditional devices are not perfect and lack facilities for easy connection with shafts of various diameters. They can only be connected to shafts of a single diameter, which reduces the flexibility of connection.

[0007] 4. Traditional devices are not perfect and lack facilities for convenient heat dissipation of the clutch body. The clutch body can only dissipate heat naturally, which reduces the heat dissipation effect. Summary of the Invention

[0008] The purpose of this invention is to provide a magnetic powder clutch with anti-leakage function to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a magnetic powder clutch with anti-leakage function, comprising a clutch body, wherein a drive shaft is respectively mounted through bearings on the front and back sides of the clutch body;

[0010] The clutch body has retaining rings installed on its front and back sides. Four support plates are installed on the inner side of the retaining rings. Two of the support plates have grooves on the side closest to the clutch body. A guide groove is provided on the inner side of the bottom wall of the retaining ring. Hooks are respectively placed through the inner side of the two grooves, and the hooks are located on the outer side of the support plates at the corresponding positions. A connecting rod is installed at the bottom of the hook. A collection box is fitted on the outer side of the two connecting rods. The top of the collection box has two movable slots, and the movable slots are located on the outer side of the connecting rods at the corresponding positions. A bolt is threaded through the side of the collection box away from the clutch body. A rubber gasket is installed at one end of the bolt, and the rubber gasket is located on the inner side of the movable slot.

[0011] Preferably, two retaining rings are installed on the outer side of the clutch body, and four retaining holes are opened through the inside of the retaining rings.

[0012] Preferably, the top of the drive shaft is provided with a pin groove, and the pin groove passes through the end of the drive shaft away from the clutch body.

[0013] Preferably, inner rings are installed on the front and back of the clutch body, respectively. The outer side of the inner ring is connected to the support plate at the corresponding position. A connecting sleeve is installed on the side of the inner ring away from the clutch body. A threaded pipe is installed on the end of the connecting sleeve away from the inner ring. A tapered sleeve is installed on the end of the threaded pipe away from the connecting sleeve. The tapered sleeve, threaded pipe and connecting sleeve are located on the outside of the drive shaft. A support sleeve is installed on the outside of the connecting sleeve. A threaded ring is installed on the outer thread of the threaded pipe. The threaded ring fits into the support sleeve. A conical hopper is embedded in the top of the support sleeve. An oil tank is installed on the top of the conical hopper. A rubber plug is installed through the top of the oil tank. A clearance groove is opened on the top of the rubber plug. A pull rope is installed through the inside of the clearance groove. The pull rope is located on the outside of the rubber plug. Multiple oil drip pipes are installed through the bottom of the conical hopper.

[0014] Preferably, the oil drip pipe passes through the side of the support sleeve closest to the clutch body;

[0015] The oil drip tube has a certain tilt angle and is aligned with the bearing on the outside of the drive shaft.

[0016] Preferably, a rubber sleeve is fitted on the outer side of the drive shaft, a bushing is installed on the outer side of the rubber sleeve, an insert block is installed on the inner side of the top wall of the bushing, a pin groove is opened on the top of the bushing, and a handle sleeve is installed on the end of the bushing near the clutch body, and the handle sleeve is located on the outer side of the cone sleeve.

[0017] Preferably, a top plate is installed on the back of the oil tank, a wind hood is inlaid on the top of the top plate, a wind net is installed on the inner side of the wind hood, a support rod is installed on one side of the inner wall of the wind hood, a fan is installed on one side of the support rod, the fan is located inside the wind hood, fan blades are installed at the top and bottom output ends of the fan, an air duct is opened through the inside of the top plate through both sides, and the air duct is connected to the bottom opening of the wind hood, a guide block is installed on the inner side of the bottom wall of the air duct, arc plates are installed on both sides of the wind hood, and the arc plates are located on the outer side of the clutch body, multiple air outlets are opened through the side of the two arc plates that are close to each other, and multiple intercepting plates are installed on one side of the inner wall of the arc plates, and each intercepting plate is located at the bottom of each air outlet.

[0018] Preferably, the magnetic powder clutch is used as follows:

[0019] S1. First, the staff can use the fixing parts to securely install the fixing ring to the work site from the fixing hole according to the actual needs, and power on the device. Then, according to the actual needs, insert the shaft pin into the inner side of the pin groove two, and put the rotating shaft to be connected into the inner side of the bushing. Then, use the pin groove two and the bushing to connect the rotating shaft to be connected to the transmission shaft, so that the clutch body can drive the transmission shaft to rotate inside the tapered sleeve, threaded tube and connecting sleeve, and drive the connected rotating shaft to rotate through the transmission shaft.

[0020] S2. Subsequently, the staff can pull the rubber stopper upwards with the pull rope as needed to open the top opening of the oil tank. Then, the staff needs to inject the lubricating oil into the inside of the oil tank from the opening. At the same time, the lubricating oil will flow through the oil tank into the inside of the drip pipe under the tilt angle of the cone and the action of gravity. The drip pipe, supported by the support sleeve and the connecting sleeve, uses the tilt angle to drip the lubricating oil onto the bearing for lubrication.

[0021] S3. The leaked lubricating oil will then fall to the inside of the retaining ring under the support of the clutch body, and flow along the retaining ring to the inside of the guide groove under the support of the support plate. Then, guided by the guide groove, the leaked lubricating oil will flow to the inside of the collection box. The collection box, through the connection rod and hook, cooperates with the groove and is supported by the support plate to collect the temporarily leaked lubricating oil. Then, the operator can rotate the bolt as needed, so that the bolt, through the thread action with the collection box, drives the rubber pad to move away from the connecting rod along the movable groove, thereby releasing the squeezing and fixing effect on the connecting rod. Then, pull the hook upward, so that the hook drives the connecting rod to move upward along the movable groove, so that the hook can be easily removed from the outside of the support plate through the groove, thereby releasing the positioning support of the collection box, allowing the operator to move the collection box to pour out the collected lubricating oil, thus preventing the lubricating oil from leaking onto the ground and polluting the environment.

[0022] S4. Finally, the staff needs to start the fan with the support of the fan cover and the support pole, so that the fan drives the fan blades to rotate inside the fan cover. Under the action of rotation, the fan blades will draw outside air through the air net into the inside of the fan cover and blow it into the inside of the air duct. At the same time, the air force will be divided into two streams into the inside of the air duct by the tilt angle and the blocking action of the air guide block. They will then blow into the inside of the two arc plates respectively. Subsequently, the intercepting plate will intercept and retain part of the air under the support of the arc plates and provide a guiding effect for the air, so that part of the air force enters and blows through the air outlet towards the clutch body. In this way, the air force is used to actively dissipate heat from the clutch body, thereby improving the heat dissipation effect of the clutch body.

[0023] Preferably, step S1 further includes the following steps:

[0024] S11. Before connecting the shaft, the staff can install the support sleeve along the shaft sleeve through the tapered sleeve and the threaded pipe on the outside of the connecting sleeve, so that the connecting sleeve provides support for the support sleeve. Then the staff needs to thread the threaded ring through the tapered sleeve and thread it to the threaded pipe, and use the thread action with the threaded pipe to move closer to the support sleeve, and cooperate with the inner ring to squeeze and fix the support sleeve.

[0025] S12. As needed, the operator can grip the handle and push the rubber sleeve away from the clutch body. Under external force, the rubber sleeve will move the bushing away from the clutch body. At the same time, the bushing will move the engaging block under external force, and the rubber sleeve will be squeezed and deformed, allowing the engaging block to slide out from the inside of the pin groove to the outside. This releases the fixing effect on the bushing, allowing the bushing and rubber sleeve to separate from the drive shaft, exposing the smaller diameter drive shaft. The operator can then fit the smaller diameter shaft to be connected onto the outside of the drive shaft and use the engagement of the pin and pin groove to fix the shaft to be connected onto the outside of the drive shaft. The drive shaft can then drive the connected shaft to rotate through the engagement of the pin and pin groove. This allows the device to be easily connected to shafts of various diameters, improving connection flexibility.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention, by installing a retaining ring, can stably support the support plate under the support of the clutch body. The support plate, supported by the inner ring, makes the retaining ring more secure. The retaining ring provides space for the guide groove, which guides leaking lubricating oil. The retaining ring also guides and receives leaking lubricating oil. The support plate provides space for the groove, which provides space for the hook, allowing the support plate to support the hook. Leaking lubricating oil, supported by the clutch body, falls onto the inner side of the retaining ring and flows along the retaining ring to the inner side of the guide groove under the support of the support plate. Subsequently, guided by the guide groove, the leaking lubricating oil... The lubricating oil flows into the inside of the collection box, which, through a connecting rod and hook, engages with a groove and is supported by a support plate to collect the temporarily leaked lubricating oil. Then, as needed, the operator can rotate the bolt, causing the threaded action of the bolt to move the rubber pad along the movable groove away from the connecting rod, thus releasing the clamping and fixing effect on the connecting rod. Next, pulling the hook upwards causes it to move the connecting rod upwards along the movable groove, allowing the hook to easily pass through the groove and be removed from the outside of the support plate. This releases the positioning support of the collection box, allowing the operator to move the collection box and empty the collected lubricating oil, preventing it from leaking onto the ground and polluting the environment.

[0028] 2. This invention features an inner ring that provides stable support to the connecting sleeve, which in turn supports the threaded tube. The threaded tube supports the tapered sleeve, and the tapered sleeve, threaded tube, and connecting sleeve together provide rotational space for the drive shaft. Before connecting the shaft, the operator can install a support sleeve along the shaft sleeve, passing through the tapered sleeve and threaded tube, on the outside of the connecting sleeve, providing support for the support sleeve. Then, the operator needs to thread the threaded ring through the tapered sleeve and connect it to the threaded tube, using the threaded action with the tube to move it closer to the support sleeve and connect it to the inner ring. The ring is used to compress and fix the support sleeve. Then, the operator can pull the rubber stopper upwards with the pull rope as needed to open the top opening of the oil tank. The operator then needs to inject lubricating oil into the inside of the oil tank through the opening. At the same time, the lubricating oil will flow through the oil tank into the inside of the drip pipe under the tilt angle of the cone and the action of gravity. The drip pipe, supported by the support sleeve and the connecting sleeve, uses the tilt angle to drip the lubricating oil onto the bearing for lubrication. This allows the device to be continuously lubricated by dripping lubricating oil, saving manpower.

[0029] 3. This invention features a rubber sleeve with a certain curvature, allowing it to deform under external force and rebound after the force disappears. The sleeve also provides support for the bushing and provides space for the second pin groove, which in turn provides a fitting space for the pin. The operator can grip the handle and push the rubber sleeve away from the clutch body as needed. This causes the bushing to move away from the clutch body under external force, simultaneously moving the fitting block along with it. The rubber sleeve is also compressed and deformed under external force, allowing the fitting block to slide out from the inside of the pin groove, thus releasing the bushing's fixing effect. This allows the bushing and rubber sleeve to separate from the drive shaft, exposing the smaller diameter drive shaft. The operator can then fit the smaller diameter shaft onto the outside of the drive shaft and use the fitting of the pin and pin groove to fix the shaft to the outside. The drive shaft can then rotate the connected shaft through the engagement of the pin and pin groove. This allows the device to easily connect to shafts of various diameters, improving connection flexibility.

[0030] 4. This invention incorporates an oil tank that provides stable support to the top plate via a cone-shaped support structure. The top plate supports the hood, which in turn provides a passageway for airflow and provides stable support for the support frame. The top plate also provides space for the air duct, which in turn provides a flow path for air. Operators can start the fan as needed, supported by the hood and support frame. The fan drives the blades to rotate inside the hood. The rotating blades draw outside air through the air mesh into the inside of the hood and then blow it into the inside of the air duct. Simultaneously, the airflow is divided into two streams by the tilting angle and blocking action of the guide blocks, entering the inside of the air duct and then blowing into the inside of two arc plates. The intercepting plates, supported by the arc plates, intercept and retain some of the airflow, guiding it to enter and pass through the outlet towards the clutch body. This active cooling of the clutch body utilizes the airflow, thereby improving its heat dissipation effect. Attached Figure Description

[0043] Please see Figure 1 and Figure 3One embodiment of the present invention provides a magnetic powder clutch with anti-leakage function, comprising a clutch body 1, two retaining rings 2 mounted on the outer side of the clutch body 1, and four retaining holes 3 penetrating through the interior of the retaining rings 2. The clutch body 1 provides stable support for the retaining rings 2, the retaining rings 2 provide space for the retaining holes 3, and the retaining holes 3 provide through channels for fixing components. Workers can use fixing components to securely install the retaining rings 2 at the work site through the retaining holes 3. A drive shaft 4 is respectively mounted through bearings on the front and back of the clutch body 1. The top of the drive shaft 4 is provided with a pin groove 5, which passes through the end of the drive shaft 4 away from the clutch body 1. The clutch body 1 can transmit torque through the drive shaft 4. The operator can insert the pin into the inner side of the pin groove 31 according to the actual needs, and put the shaft to be connected into the inner side of the bushing 28. The shaft to be connected is connected to the drive shaft 4 by the cooperation of the pin groove 31 and the bushing 28, so that the clutch body 1 can drive the drive shaft 4 to rotate inside the tapered sleeve 16, the threaded tube 17 and the connecting sleeve 18, and drive the connected shaft to rotate through the drive shaft 4.

[0044] Please see Figure 1 , Figure 2 and Figure 5One embodiment of the present invention provides a magnetic powder clutch with anti-leakage function, comprising a clutch body 1, a retaining ring 6 installed on the front and back of the clutch body 1, four support plates 7 installed on the inner side of the retaining ring 6, wherein two of the support plates 7 have grooves 8 on the side near the clutch body 1, and a guide groove 9 is formed on the inner side of the bottom wall of the retaining ring 6. Hooks 10 are respectively placed through the inner side of the two grooves 8, and the hooks 10 are located on the outer side of the support plates 7 at corresponding positions. A connecting rod 11 is installed at the bottom of the hook 10, and a collection box is fitted on the outer side of the two connecting rods 11. 12. The top of the collection box 12 has two movable slots 13, and the movable slots 13 are located on the outside of the connecting rod 11 at the corresponding positions. A bolt 14 is threaded through the side of the collection box 12 away from the clutch body 1. A rubber pad 15 is installed at one end of the bolt 14, and the rubber pad 15 is located on the inside of the movable slot 13. The retaining ring 6 can provide support for the support plate 7. The support plate 7 can provide space for the groove 8. The groove 8 can provide space for the hook 10 and has a positioning function, so that the support plate 7 can provide support for the hook 10. The hook 10 can cooperate with the connecting rod 11. Bolt 14 and rubber pad 15 support the suspension collection box 12. The rubber pad 15 has a certain elasticity and can deform under external force. After the external force is removed, it will rebound. The leaked lubricating oil will fall to the inner side of the retaining ring 6 under the support of the clutch body 1, and then flow along the retaining ring 6 to the inner side of the guide groove 9 under the support of the support plate 7. Subsequently, under the guidance of the guide groove 9, the leaked lubricating oil will flow to the inner side of the collection box 12. The collection box 12, through the connecting rod 11 and hook 10, cooperates with the groove 8 and is supported by the support plate 7 to collect and temporarily store the leaked lubricating oil. Then, the operator can adjust the collection box according to the actual situation. The bolt 14 needs to be rotated so that the bolt 14, through the thread action with the collection box 12, drives the rubber pad 15 to move away from the connecting rod 11 along the movable groove 13, thereby releasing the squeezing and fixing effect on the connecting rod 11. Then, the hook 10 is pulled upward so that the hook 10 drives the connecting rod 11 to move upward along the movable groove 13, so that the hook 10 can be easily removed from the outside of the support plate 7 through the groove 8, thereby releasing the positioning support of the collection box 12, allowing the staff to move the collection box 12 to pour out the collected lubricating oil, thereby preventing the lubricating oil from leaking onto the ground and polluting the environment.

[0045] Please see Figure 1 , Figure 2 and Figure 6An embodiment of the present invention provides a magnetic powder clutch with anti-leakage function, comprising a clutch body 1, with inner rings 19 respectively installed on the front and back of the clutch body 1. The outer side of the inner rings 19 is connected to a support plate 7 at a corresponding position. A connecting sleeve 18 is installed on the side of the inner rings 19 away from the clutch body 1. A threaded tube 17 is installed at the end of the connecting sleeve 18 away from the inner ring 19. A tapered sleeve 16 is installed at the end of the threaded tube 17 away from the connecting sleeve 18. The tapered sleeve 16, the threaded tube 17, and the connecting sleeve 18 are located on the outside of the drive shaft 4. A support sleeve 20 is fitted on the outside of the connecting sleeve 18. A threaded ring 21 is installed on the side thread, and the threaded ring 21 fits against the support sleeve 20. A conical hopper 22 is embedded in the top of the support sleeve 20, and an oil tank 23 is installed on the top of the conical hopper 22. A rubber plug 24 is installed through the top of the oil tank 23, and a relief groove 25 is opened on the top of the rubber plug 24. A pull rope 26 is installed through the inner side of the relief groove 25, and the pull rope 26 is located on the outer side of the rubber plug 24. Multiple oil drip pipes 27 are installed through the bottom of the conical hopper 22. The oil drip pipes 27 pass through the side of the support sleeve 20 near the clutch body 1. The support sleeve 20 can stably support the conical hopper 22 under the support of the inner connecting sleeve 18. 2. It has a certain inclination angle and can provide a flow channel for lubricating oil. The oil tank 23 and the conical hopper 22 cooperate to provide storage space for lubricating oil. The clearance groove 25 can provide a through channel for the pull rope 26. The pull rope 26 can be bent and deformed arbitrarily under the action of external force. Before connecting the shaft, the operator can, according to the actual needs, put the support sleeve 20 along the shaft sleeve 28 through the conical sleeve 16 and the threaded tube 17 and put it on the outside of the connecting sleeve 18 so that the connecting sleeve 18 provides support for the support sleeve 20. Then the operator needs to put the threaded ring 21 through the conical sleeve 16 and threadedly connect it to the threaded tube 17, and use the connection with the threaded tube 17 The threaded action moves closer to the support sleeve 20 and cooperates with the inner ring 19 to compress and fix the support sleeve 20. Then, the operator can pull the rubber stopper 24 upward through the pull rope 26 as needed to pull the rubber stopper 24 out of the oil tank 23 and open the opening at the top of the oil tank 23. Then, the operator needs to inject the lubricating oil into the inside of the oil tank 23 from the opening for storage. At the same time, the lubricating oil will pass through the oil tank 23 and flow into the inside of the drip pipe 27 under the tilt angle of the cone hopper 22 and the action of gravity. The drip pipe 27, supported by the support sleeve 20 and the connecting sleeve 18, uses the tilt angle to drip the lubricating oil onto the bearing for lubrication.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7This invention provides an embodiment of a magnetic powder clutch with anti-leakage function, comprising a drive shaft 4, a rubber sleeve 29 fitted on the outer side of the drive shaft 4, a bushing 28 mounted on the outer side of the rubber sleeve 29, a fitting block 30 mounted on the inner side of the top wall of the bushing 28, a pin groove 31 formed on the top of the bushing 28, and a handle 32 mounted on the end of the bushing 28 near the clutch body 1, with the handle 32 located outside the cone sleeve 16. The drive shaft 4 provides space and support for the rubber sleeve 29. The rubber sleeve 29 has a certain elasticity, can deform under external force, and will rebound when the external force disappears. It also has a certain curvature, which facilitates its mounting on the outer side of the drive shaft 4 and provides stable support for the bushing 28 under the support of the drive shaft 4. The operator can grip the handle 32 and push the rubber sleeve away from the clutch body 1 as needed. The rubber sleeve 29, under the action of external force, drives the bushing 28 to move away from the clutch body 1. At the same time, the bushing 28 will drive the fitting block 30 to move together under the action of external force. The rubber sleeve 29 will be squeezed and deformed under the action of external force, so that the fitting block 30 can slide out from the inside of the pin groove 5 to the outside, thereby releasing the fixing effect on the bushing 28. The bushing 28 and the rubber sleeve 29 can be separated from the drive shaft 4, exposing the drive shaft 4 with a smaller diameter. Then, the operator can put the smaller diameter shaft to be connected on the outside of the drive shaft 4, and use the fitting action of the shaft pin and the pin groove 5 to fix the shaft to be connected on the outside of the drive shaft 4. The drive shaft 4 can drive the connected shaft to rotate through the engagement of the shaft pin and the pin groove 5. Thus, the device can be easily connected to shafts of various diameters, improving the connection flexibility.

[0047] Please see Figure 1 and Figure 4One embodiment of the present invention provides a magnetic powder clutch with anti-leakage function, comprising an oil tank 23, a top plate 33 mounted on the back of the oil tank 23, a wind hood 34 embedded in the top of the top plate 33, a wind mesh 35 mounted on the inner side of the wind hood 34, a support rod 36 mounted on one inner wall of the wind hood 34, a fan 37 mounted on one side of the support rod 36, the fan 37 being located inside the wind hood 34, fan blades 38 mounted on the top and bottom output ends of the fan 37, and air ducts extending through both sides of the top plate 33. 39, and the air duct 39 is connected to the bottom opening of the air cover 34. An air guide block 40 is installed on the inner side of the bottom wall of the air duct 39. Arc plates 41 are installed on both sides of the air cover 34, and the arc plates 41 are located on the outer side of the clutch body 1. Multiple air outlets 42 are opened through the side of the two arc plates 41 that are close to each other. Multiple intercepting plates 43 are installed on the inner wall of one side of the arc plate 41, and each intercepting plate 43 is located at the bottom of each air outlet 42. The arc plates 41, supported by the top plate 33, can provide space for the air outlets 42. The arc plate 41 has a certain curvature, which is the same as the outer contour of the clutch body 1, and can stably support the interceptor plate 43. The interceptor plate 43 can intercept air and provide guidance for airflow. The air outlet 42 can provide a through passage for the air crew. The operator needs to start the fan 37 with the support of the wind cover 34 and the support pole 36, so that the fan 37 drives the fan blades 38 to rotate inside the wind cover 34. Under the action of rotational power, the fan blades 38 will draw outside air through the air mesh 35 and into the inside of the wind cover 34. The wind passes through the shroud 34 and blows into the inner side of the air duct 39. At the same time, the wind force is divided into two streams by the tilt angle and the blocking effect of the air guide block 40 and enters the inner side of the air duct 39. They then pass through the air duct 39 and blow into the inner side of the two arc plates 41 respectively. Subsequently, the intercepting plate 43 intercepts and retains part of the wind under the support of the arc plates 41 and provides a guiding effect for the wind, so that part of the wind force enters and passes through the air outlet 42 and blows towards the clutch body 1. In this way, the wind force is used to actively dissipate heat from the clutch body 1, thereby improving the heat dissipation effect of the clutch body 1.

[0048] Furthermore, the method of using the magnetic powder clutch is as follows:

[0049] S1. First, the staff can use the fixing parts to securely install the fixing ring 2 to the work site from the fixing hole 3 according to the actual needs, and power on the device. Then, according to the actual needs, the shaft pin is inserted into the inner side of the pin groove 31, and the shaft to be connected is fitted into the inner side of the bushing 28. The shaft to be connected is connected to the transmission shaft 4 by using the pin groove 31 and the bushing 28. This allows the clutch body 1 to drive the transmission shaft 4 to rotate inside the tapered sleeve 16, the threaded tube 17 and the connecting sleeve 18, and drive the connected shaft to rotate through the transmission shaft 4.

[0050] S2. Subsequently, the staff can pull the rubber stopper 24 upwards using the pull rope 26 as needed, so that the rubber stopper 24 is pulled out from inside the oil tank 23 to open the opening at the top of the oil tank 23. Then, the staff needs to inject the lubricating oil into the inside of the oil tank 23 from the opening for storage. At the same time, the lubricating oil will pass through the oil tank 23 and flow into the inside of the drip pipe 27 under the tilt angle of the cone hopper 22 and the action of gravity. The drip pipe 27, supported by the support sleeve 20 and the connecting sleeve 18, uses the tilt angle to drip the lubricating oil onto the bearing for lubrication.

[0051] S3. The leaked lubricating oil will then fall into the inner side of the retaining ring 6 under the support of the clutch body 1, and flow along the retaining ring 6 to the inner side of the guide groove 9 under the support of the support plate 7. Then, under the guidance of the guide groove 9, the leaked lubricating oil will flow into the inner side of the collection box 12. The collection box 12, through the connecting rod 11 and the hook 10, cooperates with the groove 8 and is supported by the support plate 7 to collect the temporarily leaked lubricating oil. Then, the operator can rotate the bolt 14 as needed, so that the bolt 14, through the thread action with the collection box 12, drives the rubber pad 15 to move away from the connecting rod 11 along the movable groove 13, thereby releasing the squeezing and fixing effect on the connecting rod 11. Then, pull the hook 10 upward, so that the hook 10 drives the connecting rod 11 to move upward along the movable groove 13, so that the hook 10 can be easily removed from the outside of the support plate 7 through the groove 8, thereby releasing the positioning support of the collection box 12, so that the operator can move the collection box 12 to pour out the collected lubricating oil, thereby preventing the lubricating oil from leaking onto the ground and polluting the environment.

[0052] S4. Finally, the operator needs to start the fan 37 with the support of the fan cover 34 and the support rod 36. The fan 37 drives the fan blades 38 to rotate inside the fan cover 34. The fan blades 38 will draw outside air through the air net 35 into the inside of the fan cover 34 under the action of rotational power, and blow it into the inside of the air duct 39 through the fan cover 34. At the same time, the wind force will be divided into two streams into the inside of the air duct 39 by the tilt angle and the blocking action of the air guide block 40. They will then blow into the inside of the two arc plates 41 respectively through the air duct 39. Subsequently, the intercepting plate 43 will intercept and retain part of the wind under the support of the arc plates 41 and provide a guiding effect for the wind, so that part of the wind force enters and blows through the air outlet 42 towards the clutch body 1. In this way, the wind force is used to actively dissipate heat from the clutch body 1, thereby improving the heat dissipation effect of the clutch body 1.

[0053] Furthermore, step S1 also includes the following steps:

[0054] S11. Before connecting the shaft, the staff can, according to the actual situation, put the support sleeve 20 along the shaft sleeve 28 through the tapered sleeve 16 and the threaded tube 17 on the outside of the connecting sleeve 18 so that the connecting sleeve 18 provides support for the support sleeve 20. Then, the staff needs to put the threaded ring 21 through the tapered sleeve 16 and threadedly connect it to the threaded tube 17, and use the thread action with the threaded tube 17 to move closer to the support sleeve 20, and cooperate with the inner ring 19 to squeeze and fix the support sleeve 20.

[0055] S12. As needed, the operator can grip the grip 32 and push the rubber sleeve 29 away from the clutch body 1. Under the action of external force, the rubber sleeve 29 will drive the bushing 28 to move away from the clutch body 1. At the same time, the bushing 28 will drive the fitting block 30 to move together under the action of external force. The rubber sleeve 29 will be squeezed and deformed under the action of external force, so that the fitting block 30 can slide out from the inside of the pin groove 5 to the outside, thereby releasing the fixing effect on the bushing 28. The bushing 28 and the rubber sleeve 29 can be separated from the drive shaft 4, exposing the drive shaft 4 with a smaller diameter. Then, the operator can put the smaller diameter shaft to be connected on the outside of the drive shaft 4 and use the fitting action of the shaft pin and the pin groove 5 to fix the shaft to be connected on the outside of the drive shaft 4. The drive shaft 4 can drive the connected shaft to rotate through the engagement of the shaft pin and the pin groove 5. Thus, the device can be easily connected to shafts of various diameters, improving the connection flexibility.

[0056] Working principle: Before using the device, it is necessary to check whether there are any problems that may affect its use. When the operator needs to use the device, the device should be placed firmly at the work site using the fixing ring 2. The clutch body 1 should be firmly installed at the work site using the fixing component through the fixing hole 3 in conjunction with the fixing ring 2. At the same time, according to the actual needs, the shaft to be connected should be connected to the drive shaft 4 or bushing 28 from the pin groove 5 or pin groove 21. The clutch body 1 should be powered on. Then, the operator needs to start the fan 37 with the support of the top plate 33 and the fan cover 34, so that the fan 37 drives the fan blade 38 to rotate and blow air to the outside of the clutch body 1 for active heat dissipation. Then, according to the actual needs, lubricating oil should be injected into the inside of the oil tank 23, and the oil dripping pipe 27 should drip lubricating oil to the outside of the drive shaft 4 for lubrication. After a period of time, the operator needs to loosen the bolt 14, remove the hook 10, move the collection box 12 and pour out the collected leaked lubricating oil.
