Description

Technical Field

[0001] This invention relates to the field of speed reducers for transporting metallurgical products, specifically a compact speed reducer for metallurgical applications with overload protection. Background Technology

[0002] With the rapid development of industry and to meet production demands, numerous production equipment have emerged, especially speed reducers. A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine, matching speed and transmitting torque between the prime mover and the working machine or actuator. It is widely used in modern machinery. Speed ​​reducers are generally used in low-speed, high-torque transmission equipment. They reduce the speed of electric motors, internal combustion engines, or other high-speed power sources by meshing a small gear on the input shaft with a large gear on the output shaft. Speed ​​reducers are relatively precise machines that match speed and transmit torque between the prime mover and the working machine or actuator. Their purpose is to reduce speed and increase torque to meet work requirements. In some cases, they are also used to increase speed, and are called speed increasers. In the metallurgical production process, speed reducers are often used to drive rollers or gears, which in turn drive belts or chains to rotate, thus transporting metallurgical products.

[0003] Chinese Patent (Application No.: CN202021793775.6) discloses an adjustable overload-resistant speed reducer. In this application, a microcontroller is used to operate a water pump, which draws cooling water from the water tank through a water pipe. The water is then cooled by a cooling pipe spirally wound around the outer side of the speed reducer before being returned to the water tank. This cooling method effectively prevents the speed reducer from overloading due to high internal temperatures, thus avoiding damage to internal components caused by high-temperature overload.

[0004] The method of cooling the reducer by spirally winding a cooling pipe around its outer side results in a slow cooling rate and an unsatisfactory cooling effect, leading to overload operation of the reducer. Summary of the Invention

[0005] The purpose of this invention is to provide a compact speed reducer with overload protection for metallurgical applications, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a compact metallurgical reducer with overload protection function, comprising a reducer, a cover and a heat-conducting plate mounted on the reducer, the cover and the heat-conducting plate forming a cooling chamber, the heat-conducting plate being in contact with the reducer, a temperature sensor mounted on the heat-conducting plate, a refrigeration box mounted on the reducer, the refrigeration box containing a refrigerator, and the refrigeration box being connected to the cooling chamber via a pipeline. When high temperature is generated inside the reducer, the heat inside the reducer is quickly absorbed by the heat-conducting plate and then transferred to the cooling chamber. Coolant is stored in the cooling chamber, which is composed of a casing and a heat-conducting plate. The coolant rapidly cools the heat-conducting plate. By activating the pump in the pipeline, the coolant in the refrigeration box and the coolant in the cooling chamber circulate. At this time, the refrigerator can cool the coolant carrying heat, which helps the heat-conducting plate to continuously absorb heat from the reducer. When the temperature sensor detects that the coolant temperature has increased, the refrigeration temperature of the refrigerator can be adjusted accordingly. Furthermore, controlling the pump to run at high speed can increase the circulation rate of the coolant and ensure the cooling effect of the coolant.

[0007] As a preferred technical solution, the pipeline includes a pump body, a first infusion pipe, a second infusion pipe, and a return pipe;

[0008] The refrigeration box is equipped with a pump body. The input end of the pump body is connected to the output end of the refrigeration box through a first liquid delivery pipe. The output end of the pump body is connected to the cooling chamber through a second liquid delivery pipe. The cooling chamber is connected to the input end of the refrigeration box through a return pipe. The first liquid delivery pipe, the second liquid delivery pipe, and the return pipe form a coolant circulation channel, which facilitates the flow of cooled coolant in the refrigeration box into the cooling chamber through the first and second liquid delivery pipes. Meanwhile, the coolant carrying heat in the cooling chamber can flow back into the refrigeration box through the return pipe to be cooled again, thereby ensuring the cooling effect.

[0009] As a preferred technical solution, the reducer is equipped with a primary flow rate utilization component, a secondary flow rate utilization component, and a tertiary flow rate utilization component. The rapid flow of liquid in the coolant circulation channel provides the driving force for the primary flow rate utilization component. The primary flow rate utilization component, the secondary flow rate utilization component, and the tertiary flow rate utilization component cooperate with each other, and the primary flow rate utilization component provides the driving force for the secondary flow rate utilization component and the tertiary flow rate utilization component.

[0010] As a preferred technical solution, the flow rate primary utilization component includes a housing, a first moving ring, a first transmission rod, a perforation, a linkage ring, a first return spring, and a branch pipe;

[0011] The reducer is equipped with a housing, and a first moving ring is slidably mounted inside the housing. A first transmission rod is mounted on the first moving ring. A through hole is provided on the housing, through which the first transmission rod passes, and a linkage ring is mounted on the first transmission rod. The first moving ring is connected to the inner wall of the housing via a first return spring. The housing is connected to a second infusion pipe via a branch pipe, and a one-way valve is installed on the branch pipe. The one-way valve ensures that the coolant in the second infusion pipe does not enter the branch pipe. When the flow rate of the coolant in the second infusion pipe increases, the second infusion pipe can draw gas from the housing through the branch pipe by utilizing the pipe pressure difference, creating a negative pressure in the housing. This negative pressure causes the first moving ring to compress the first return spring and move laterally. Since the first transmission rod and the through hole are in a sliding fit, the first moving ring can drive the linkage ring to move synchronously during the lateral movement via the first transmission rod.

[0012] As a preferred technical solution, the flow rate secondary utilization component includes a bearing, a linkage plate, a sleeve hole, and a cross-shaped groove hole;

[0013] The reducer is equipped with a rotating shaft, the end of which is cross-shaped. A rotating rod is mounted on the rotating shaft, and a cross-shaped slot is formed on the rotating rod. The rotating shaft passes through the cross-shaped slot and is fitted into it. A linkage plate is mounted on the inner diameter of the linkage ring via a bearing. A sleeve hole is formed on the linkage plate, through which the rotating shaft passes. When the linkage ring moves, it can drive the linkage plate to move synchronously, so that the sleeve hole on the linkage plate passes through the cross end of the rotating shaft and fits against the rotating rod. This facilitates the linkage plate to fit the cross end of the rotating shaft and the cross-shaped slot of the rotating rod into place, allowing the linkage plate to seal the fit between the cross end of the rotating shaft and the cross-shaped slot of the rotating rod. At the same time, the rotation of the bearing allows the linkage plate to rotate synchronously with the rotation of the rotating shaft and the rotating rod, without affecting the transmission of the reducer.

[0014] As a preferred technical solution, the sleeve hole is "+" shaped, and the cross-sectional shape and size of the sleeve hole and the cross groove hole are the same, which can ensure the sealing effect of the linkage plate at the joint between the cross end of the rotating shaft and the cross groove hole of the rotating rod.

[0015] As a preferred technical solution, the three-stage flow rate utilization component includes an emergency box, a compression ring, a second transmission rod, a through hole, a second moving ring, a second return spring, a chamber, an oil seepage hole, and a connecting pipe;

[0016] An emergency box containing lubricant is mounted on the rotating rod. A compression ring is slidably mounted inside the emergency box, and a second transmission rod is mounted on the compression ring. The emergency box has a through hole through which the second transmission rod slides, and a second moving ring is mounted on the second transmission rod. The second moving ring is connected to the emergency box via a second return spring. The rotating rod has a chamber that communicates with the wall of the cross-shaped slot through an oil seepage hole. The chamber is also connected to the emergency box via a connecting pipe. When the linkage ring moves laterally, it presses the second moving ring, causing the second moving ring to move synchronously with the linkage ring. Because the second transmission rod and the through hole are in a sliding fit, the second moving ring can squeeze the lubricating oil in the emergency box through the compression ring via the second transmission rod. Under this squeezing action, the lubricant in the emergency box can enter the chamber through the connecting pipe and then flow into the cross-shaped slot through the oil seepage hole. This helps reduce wear between the rotating shaft and the rotating rod, ensuring the transmission effect of the rotating shaft to the rotating rod.

[0017] As a preferred technical solution, the second moving ring is provided with a groove, and a ball is rolled and embedded in the groove. When the first moving ring moves, the first moving ring comes into contact with the ball. Since the ball can roll in the groove, it is beneficial to reduce the rotational friction between the second moving ring and the linkage ring when the second moving ring presses the linkage ring.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] When high temperatures are generated inside the reducer, the heat is quickly absorbed by the heat-conducting plate. Since the cooling chamber, which is composed of the casing and the heat-conducting plate, stores coolant, the heat-conducting plate is rapidly cooled by the coolant. Furthermore, by activating the pump in the pipeline, the coolant in the refrigeration box and the coolant in the cooling chamber circulate. At this time, the coolant carrying heat can be cooled by the refrigerator, which helps the heat-conducting plate to continuously absorb heat from the reducer. When the temperature sensor detects that the temperature of the coolant has increased, the cooling temperature of the refrigerator can be adjusted accordingly to ensure the cooling effect of the coolant.

[0020] When the flow rate of the coolant in the second infusion tube increases, the pressure difference in the pipeline allows the second infusion tube to draw gas from the box through the branch pipe, creating a negative pressure in the box. This negative pressure causes the first moving ring to compress the first return spring and move laterally. Since the first transmission rod and the perforation are in sliding fit, the first moving ring can drive the linkage ring to move synchronously during the lateral movement through the first transmission rod.

[0021] When the linkage ring moves laterally, it presses the second moving ring during the movement, causing the second moving ring to drive the linkage ring to move synchronously. Since the second transmission rod and the through hole are in sliding fit, the second moving ring can drive the compression ring to squeeze the lubricating emulsion in the emergency box during the movement. Under the action of compression, the lubricant in the emergency box can enter the chamber through the connecting pipe, and then flow into the cross groove hole through the oil seepage hole. This helps to reduce the wear between the shaft and the rod, and ensures the transmission effect of the shaft to the rod. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-6 As shown, the present invention provides the following technical solution: a compact metallurgical reducer with overload protection function, comprising a reducer 1, a cover 4 and a heat-conducting plate 5 mounted on the reducer 1, the cover 4 and the heat-conducting plate 5 forming a cooling chamber, initially filled with coolant, the heat-conducting plate 5 in contact with the reducer 1, a temperature sensor 11 mounted on the heat-conducting plate 5, a refrigeration box 6 mounted on the reducer 1, the refrigeration box 6 storing coolant, a refrigerator 12 mounted on the refrigeration box 6, and the refrigeration box 6 connected to the cooling chamber via a pipeline, when the reducer 1... When high temperatures are generated inside, the heat is quickly absorbed by the heat-conducting plate 5. Since the cooling chamber formed by the casing 4 and the heat-conducting plate 5 contains coolant, the heat-conducting plate 5 is quickly cooled by the coolant. Furthermore, by starting the pump 7 in the pipeline, the coolant in the refrigeration box 6 and the coolant in the cooling chamber circulate. At this time, the cooler 12 can cool the coolant carrying heat, which is beneficial for the heat-conducting plate 5 to continuously absorb the heat in the reducer 1. When the temperature sensor 11 detects that the heat of the coolant has increased, the cooling temperature of the cooler 12 can be adjusted accordingly to ensure the cooling effect of the coolant.

[0035] like Figures 1-2 and Figure 4 As shown, the pipeline includes a pump body 7, a first infusion pipe 8, a second infusion pipe 9, and a return pipe 10;

[0036] A pump body 7 is installed on the refrigeration box 6. The input end of the pump body 7 is connected to the output end of the refrigeration box 6 through a first liquid delivery pipe 8. The output end of the pump body 7 is connected to the cooling chamber through a second liquid delivery pipe 9. The cooling chamber is connected to the input end of the refrigeration box 6 through a return pipe 10. The first liquid delivery pipe 8, the second liquid delivery pipe 9 and the return pipe 10 form a coolant circulation channel, which facilitates the flow of the cooled coolant in the refrigeration box 6 into the cooling chamber through the first liquid delivery pipe 8 and the second liquid delivery pipe 9. Meanwhile, the coolant carrying heat in the cooling chamber can flow back into the refrigeration box 6 through the return pipe 10 to be cooled again, thereby ensuring the cooling effect.

[0037] The reducer 1 is equipped with a primary flow rate utilization component 13, a secondary flow rate utilization component 14, and a tertiary flow rate utilization component 15. The rapid flow of liquid in the coolant circulation channel provides the driving force for the primary flow rate utilization component 13. The primary flow rate utilization component 13, the secondary flow rate utilization component 14, and the tertiary flow rate utilization component 15 cooperate with each other, and the primary flow rate utilization component 13 provides the driving force for the secondary flow rate utilization component 14 and the tertiary flow rate utilization component 15.

[0038] like Figures 1-2 and Figures 4-5 As shown, the flow rate primary utilization component 13 includes a housing 1301, a first moving ring 1302, a first transmission rod 1303, a perforation 1304, a linkage ring 1305, a first return spring 1306, and a branch pipe 1307.

[0039] A housing 1301 is mounted on the reducer 1. A first moving ring 1302 is slidably mounted inside the housing 1301. There is a gap between the first moving ring 1302 and the bottom of the housing 1301, and an air hole is provided at the gap. A first transmission rod 1303 is mounted on the first moving ring 1302. A through hole 1304 is provided on the housing 1301, through which the first transmission rod 1303 passes. A linkage ring 1305 is mounted on the first transmission rod 1303. The first moving ring 1302 is connected to the inner wall of the housing 1301 via a first return spring 1306. The housing 1301 is connected to the second infusion tube 9 via a branch pipe 1307. A one-way valve is installed on the branch pipe 1307. The one-way valve can ensure that the coolant in the second infusion pipe 9 will not enter the branch pipe 1307. When the flow rate of the coolant in the second infusion pipe 9 increases, the second infusion pipe 9 can draw the gas in the box 1301 through the branch pipe 1307 by utilizing the pipeline pressure difference, so that a negative pressure is formed in the box 1301. This allows the first moving ring 1302 to compress the first return spring 1306 and move laterally under the action of the negative pressure. Since the first transmission rod 1303 and the through hole 1304 are in sliding fit, the first moving ring 1302 can drive the linkage ring 1305 to move synchronously during the lateral movement through the first transmission rod 1303.

[0040] like Figures 1-2 and Figures 4-5 As shown, the flow rate secondary utilization component 14 includes a bearing 1401, a linkage plate 1402, a sleeve hole 1403, and a cross groove hole 1404.

[0041] The reducer 1 is equipped with a rotating shaft 2, the end of which is cross-shaped. A rotating rod 3 is mounted on the rotating shaft 2, and a cross-shaped slot 1404 is formed on the rotating rod 3. The rotating shaft 2 is inserted into the cross-shaped slot 1404 and is fitted into it. A linkage plate 1402 is mounted on the inner diameter of the linkage ring 1305 via a bearing 1401. A sleeve hole 1403 is formed on the linkage plate 1402, and the rotating shaft 2 passes through the sleeve hole 1403. When the linkage ring 1305 moves, it can drive... The linkage plate 1402 is synchronously displaced, so that the sleeve hole 1403 on the linkage plate 1402 passes through the cross end of the rotating shaft 2 and fits against the rotating rod 3. This facilitates the fitting of the linkage plate 1402 with the cross end of the rotating shaft 2 and the cross groove hole 1404 of the rotating rod 3, allowing the linkage plate 1402 to seal the fitting of the cross end of the rotating shaft 2 and the cross groove hole 1404 of the rotating rod 3. At the same time, through the rotation of the bearing 1401, the linkage plate 1402 rotates synchronously with the rotation of the rotating shaft 2 and the rotating rod 3, without affecting the transmission of the reducer 1.

[0042] The sleeve hole 1403 is cross-shaped, and the cross-sectional shape and size of the sleeve hole 1403 and the cross groove hole 1404 are the same, which can ensure the sealing effect of the linkage plate 1402 at the joint between the cross end of the rotating shaft 2 and the cross groove hole 1404 of the rotating rod 3.

[0043] like Figures 1-4 and Figure 6 As shown, the flow rate three-stage utilization component 15 includes an emergency box 1501, a compression ring 1502, a second transmission rod 1503, a through hole 1504, a second moving ring 1505, a second return spring 1506, a chamber 1507, an oil seepage hole 1508, and a connecting pipe 1509.

[0044] An emergency box 1501 is mounted on the rotating rod 3. The emergency box 1501 contains lubricant. A compression ring 1502 is slidably mounted inside the emergency box 1501. A second transmission rod 1503 is mounted on the compression ring 1502. A through hole 1504 is formed in the emergency box 1501, through which the second transmission rod 1503 slides. A second moving ring 1505 is mounted on the second transmission rod 1503. The second moving ring 1505 is connected to the emergency box 1501 via a second return spring 1506. A chamber 1507 is provided inside the rotating rod 3. The chamber 1507 communicates with the wall of the cross-shaped slot hole 1404 through an oil seepage hole 1508. The chamber 1507 and the emergency box 1501 are connected by a connecting pipe. When the linkage ring 1305 moves laterally, it presses the second moving ring 1505 during the movement, causing the second moving ring 1505 to drive the linkage ring 1305 to move synchronously. Since the second transmission rod 1503 and the through hole 1504 are in sliding fit, the second moving ring 1505 can drive the compression ring 1502 to squeeze the lubricating oil in the emergency box 1501 through the second transmission rod 1503 during the movement. Under the action of compression, the lubricant in the emergency box 1501 can enter the chamber 1507 through the connecting pipe 1509, and then flow into the cross groove hole 1404 through the oil seepage hole 1508. This helps to reduce the wear between the rotating shaft 2 and the rotating rod 3 and ensures the transmission effect of the rotating shaft 2 to the rotating rod 3.

[0045] The second moving ring 1505 has a rolling groove 1510, in which a ball 1511 is rolled and fitted. When the linkage ring 1305 moves, the linkage ring 1305 comes into contact with the ball 1511. Since the ball 1511 can roll in the rolling groove 1510, it is beneficial to reduce the rotational friction between the second moving ring 1505 and the linkage ring 1305 when the second moving ring 1505 presses the linkage ring 1305.

[0046] Working principle of the invention:

[0047] When high temperatures are generated inside the reducer 1, the heat is quickly absorbed by the heat-conducting plate 5. Since the cooling chamber formed by the casing 4 and the heat-conducting plate 5 contains coolant, the heat-conducting plate 5 is quickly cooled by the coolant. Furthermore, by starting the pump 7 in the pipeline, the coolant in the refrigeration box 6 and the coolant in the cooling chamber circulate. At this time, the cooler 12 can cool the coolant carrying heat, which is beneficial for the heat-conducting plate 5 to continuously absorb the heat in the reducer 1. When the temperature sensor 11 detects that the heat of the coolant has increased, the cooling temperature of the cooler 12 can be adjusted accordingly to ensure the cooling effect of the coolant.

[0048] When the flow rate of the coolant in the second infusion pipe 9 increases, the pressure difference in the pipe allows the second infusion pipe 9 to draw gas from the box 1301 through the branch pipe 1307, creating a negative pressure in the box 1301. This causes the first moving ring 1302 to compress the first return spring 1306 and move laterally under the negative pressure. Since the first transmission rod 1303 and the through hole 1304 are in sliding fit, the first moving ring 1302 can drive the linkage ring 1305 to move synchronously during the lateral movement through the first transmission rod 1303.

[0049] When the linkage ring 1305 moves, it can drive the linkage plate 1402 to move synchronously, so that the sleeve hole 1403 on the linkage plate 1402 passes through the cross end of the rotating shaft 2 and fits against the rotating rod 3. This facilitates the fitting of the linkage plate 1402 with the cross end of the rotating shaft 2 and the cross groove hole 1404 of the rotating rod 3, and allows the linkage plate 1402 to seal the fitting of the cross end of the rotating shaft 2 and the cross groove hole 1404 of the rotating rod 3. At the same time, through the rotation of the bearing 1401, the linkage plate 1402 can rotate synchronously with the rotation of the rotating shaft 2 and the rotating rod 3, without affecting the transmission of the reducer 1.

[0050] When the linkage ring 1305 moves laterally, it presses the second moving ring 1505 during the movement, so that the second moving ring 1505 can drive the linkage ring 1305 to move synchronously. Since the second transmission rod 1503 and the through hole 1504 are in sliding fit, the second moving ring 1505 can drive the compression ring 1502 to squeeze the lubricating emulsion in the emergency box 1501 through the second transmission rod 1503 during the movement. Under the action of compression, the lubricant in the emergency box 1501 can enter the chamber 1507 through the connecting pipe 1509, and then flow into the cross groove hole 1404 through the oil seepage hole 1508. This helps to reduce the wear between the rotating shaft 2 and the rotating rod 3 and can ensure the transmission effect of the rotating shaft 2 to the rotating rod 3.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

An emergency box (1501) is installed on the rotating rod (3). The emergency box (1501) contains lubricant. A compression ring (1502) is slidably installed inside the emergency box (1501). A second transmission rod (1503) is installed on the compression ring (1502). A through hole (1504) is opened on the emergency box (1501). The second transmission rod (1503) passes through the through hole (1504) and is in sliding fit. A second moving ring (1505) is installed on (1503). The second moving ring (1505) is connected to the emergency box (1501) through a second return spring (1506). The rotating rod (3) is provided with a chamber (1507). The chamber (1507) is connected to the wall of the cross slot hole (1404) through an oil seepage hole (1508). The chamber (1507) is connected to the emergency box (1501) through a connecting pipe (1509). The second moving ring (1505) has a rolling groove (1510) and a ball (1511) is rolled and fitted in the rolling groove (1510). When the linkage ring (1305) moves, the linkage ring (1305) comes into contact with the ball (1511). When high temperature is generated inside the reducer (1), the heat inside the reducer (1) is quickly absorbed by the heat-conducting plate (5). Since the cooling chamber formed by the cover (4) and the heat-conducting plate (5) contains coolant, the heat-conducting plate (5) is cooled down quickly by the coolant. In addition, by starting the pump (7) in the pipeline, the coolant in the refrigeration box (6) and the coolant in the cooling chamber are circulated. At this time, the cooler (12) can cool down the coolant carrying heat, which is beneficial for the heat-conducting plate (5) to continuously absorb the heat in the reducer (1). When the temperature sensor (11) detects that the heat of the coolant has increased, the cooling temperature of the cooler (12) can be adjusted accordingly to ensure the cooling effect of the coolant. When the flow rate of the coolant in the second infusion pipe (9) increases, by utilizing the pressure difference in the pipe, the second infusion pipe (9) can draw gas from the box (1301) through the branch pipe (1307), so that a negative pressure is formed in the box (1301), thereby enabling the first moving ring (1302) to compress the first return spring (1306) under the action of negative pressure and move laterally. Since the first transmission rod (1303) and the perforation (1304) are in sliding fit, the first moving ring (1302) can drive the linkage ring (1305) to move synchronously during the lateral movement through the first transmission rod (1303); When the linkage ring (1305) moves, the linkage ring (1305) can drive the linkage plate (1402) to move synchronously, so that the sleeve hole (1403) on the linkage plate (1402) passes through the cross end of the rotating shaft (2) and fits with the rotating rod (3). This is beneficial for the linkage plate (1402) to fit with the cross end of the rotating shaft (2) and the cross groove hole (1404) of the rotating rod (3), and can seal the cross end of the rotating shaft (2) and the cross groove hole (1404) of the rotating rod (3). At the same time, through the rotation of the bearing (1401), the linkage plate (1402) can rotate synchronously with the rotation of the rotating shaft (2) and the rotating rod (3), without affecting the transmission of the reducer (1). When the linkage ring (1305) moves laterally, the linkage ring (1305) presses the second moving ring (1505) during the movement, so that the second moving ring (1505) can drive the linkage ring (1305) to move synchronously. Since the second transmission rod (1503) and the through hole (1504) are in sliding fit, the second moving ring (1505) can drive the extrusion ring (1502) to extrude the lubricating emulsion in the emergency box (1501) through the second transmission rod (1503) during the movement. Under the extrusion action, the lubricant in the emergency box (1501) can enter the chamber (1507) through the connecting pipe (1509), and then flow into the cross groove hole (1404) through the oil seepage hole (1508), which helps to reduce the wear between the rotating shaft (2) and the rotating rod (3) and can ensure the transmission effect of the rotating shaft (2) to the rotating rod (3).
