Description

Technical Field

[0001] The present invention relates to the technical field of power transmission cutting off and inputting, and in particular to a device for realizing power transmission cutting off and inputting. Background Art

[0002] The liquid-viscous clutch controls the clearance of the friction pair, thereby changing the thickness of the oil film and using the viscous shear force of the oil to adjust the speed. The oil film shear force will drive the output part to rotate. In previous designs, the total clearance of the liquid-viscous clutch is constant. When the clutch is disengaged, the presence of the lubricating oil will also cause the generation of the belt torque. Especially in low-temperature environments and when the oil viscosity is very high, the belt torque caused by it is abnormally large. When the load inertia is relatively small, it will cause a large power loss during startup. For example, when the liquid-viscous clutch is used to drive the fan, the increased viscosity caused by the low temperature will cause the fan belt speed to be high, which is contrary to the low-temperature use requirements. Therefore, in order to avoid this situation, at the same time, the purpose of suppressing the belt torque and reducing the belt speed is achieved in a limited space. In view of the above situation, how to develop a liquid-viscous clutch with small belt torque, simple structure and strong reliability is a direction and goal that technicians in this field urgently need to strive to achieve.

[0003] Publication (Announcement) No.: CN114810855B relates to a liquid-viscous clutch with a hydraulic power cut-off device. The liquid-viscous clutch integrates the hydraulic power on-off device with the clutch body. The power is input by the input gear, and then the two-way piston connecting the input gear and the outer hub transmits the power between the two. The hydraulic pressure drives the two-way piston to switch the power on and off. When the two-way piston is only connected to the outer hub, the input gear idles; when the two-way piston is connected to the input gear and the outer hub at the same time, the power is transmitted to the clutch body; the power of the clutch body is input through the outer hub, and the outer hub is connected to the active friction plate. The main piston is pushed by the main oil cylinder to control the friction pair clearance, thereby driving the main shaft connected to the passive friction plate to rotate, and the clutch performs normal speed regulation and operation. It can realize the transmission and speed regulation of the power of the liquid-viscous clutch, and can ensure that there is no power output when the power needs to be cut off, thereby reducing the belt displacement loss caused by the viscosity of the oil.

[0004] The existing clutch is inconvenient to use for transmission connection, and has no good cooling method when working for a long time, which shortens the service life. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the existing clutch, such as inconvenient use for transmission connection, no good cooling method for long-term work, and shortening of service life, and to propose a device for realizing power transmission cutting and input.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A housing is used to support and connect the clutch, a fixed seat is fixedly installed on the top of the housing, a moving inclined block is fixedly installed on the top of the fixed seat, a transmission sleeve is rotatably installed inside the moving inclined block through a bearing, an embedded block is slidably arranged on the inner side of the transmission sleeve, a power shaft is slidably installed on the outer side of the embedded block, and a bolt is connected between the power shaft and the embedded block;

The inner side of the power shaft is provided with a recessed claw. The raised claw cooperates with the recessed claw. The recessed claws are evenly distributed inside the power shaft. The recessed claws can be divided into multiple groups, such as 8 groups. The larger the inner diameter of the power shaft, the more groups there can be. The recessed claws of the power shaft form a matching relationship with the raised claws of the transmission sleeve.

[0010] A fan mechanism is rotatably arranged inside the housing to cool the entire unit;

[0011] The cooling mechanism is arranged on the shell and is used for cooling the air. A control box is arranged on the outer side of the shell and a push switch is arranged on the control box.

[0012] Preferably, the outer sleeve of the output shaft is provided with a compression spring, the top end of the compression spring is fixedly mounted to the inner side of the embedded block, the bottom end of the compression spring is fixedly mounted to the bottom inner wall of the transmission sleeve, and the compression spring is an annular structure.

[0015] Preferably, a rotating arm is arranged on the circumference of the movable inclined block, and the rotating arm can be driven by a pull wire, a push rod, or an electromagnetic push rod to make the rotating arm rotate, thereby prompting the movable inclined block to rotate and then move axially.

[0016] Preferably, an electromagnet is arranged on the outer ring of the movable bevel block, and a suction circle is arranged on the top of the movable bevel block. When the electromagnet is energized, it attracts the suction circle to generate a magnetic attraction, and the movable bevel block overcomes the elastic force of the central compression spring and moves upward axially, thereby realizing the power transmission function. On the contrary, when the electromagnet loses power, the elastic force of the compression spring prompts the movable block to cut off the power transmission, and a compression spring is arranged inside the transmission sleeve. When the transmission sleeve moves driven by the movable bevel block, the elastic force of the compression spring exerts an axial thrust on the transmission sleeve. Under the thrust, the axial movement of the transmission sleeve starts smoothly without fluctuations and unstable movement. At the same time, when the transmission sleeve is not acted upon by an external axial force, the compression spring starts to reset.

[0017] Preferably, the fan mechanism includes a fan shaft, which is rotatably mounted on the bottom inner wall of the casing through a bearing, a connecting piece is fixedly mounted on the top of the fan shaft, a polygonal groove matching the output shaft is formed on the top of the connecting piece, and a locking bolt is threadedly connected to the outer side of the connecting piece, and the locking bolt is used to fix the output shaft to the connecting piece.

[0018] Preferably, fan blades are installed on the outside of the fan shaft, and a plurality of air inlet holes are opened at the bottom of the shell; the output shaft rotates to drive the fan blades, and external air enters the interior of the shell to blow and cool down.

[0020] Preferably, a cylinder is installed on the inner wall of the shell, and a cooling reflux pipe and a liquid suction pipe are installed on the outside of the cylinder, the cooling reflux pipe and the liquid suction pipe are located on different sides, the other end of the cooling reflux pipe is connected to the top of the cooling box, and the other end of the liquid suction pipe is connected to the bottom side of the cooling box, and a water inlet and a water outlet are provided on the outside of the cylinder, the water inlet is welded to the liquid suction pipe, and the water outlet is connected to the cooling reflux pipe.

[0021] Preferably, a rotating rod is rotatably installed in the cylinder through a sealed bearing, and a spiral blade is provided on the outer side of the rotating rod located inside the cylinder, and the spiral blade is slidably connected to the inner wall of the cylinder, and a first bevel gear is fixedly installed on the outer end of the rotating rod, and a second bevel gear is sleeved on the outer side of the fan shaft, and the first bevel gear is meshed with the second bevel gear; the output shaft drives the rotating rod to rotate through the second bevel gear and the first bevel gear, and the rotating rod drives the spiral blade to rotate in the cylinder, and the coolant enters the cylinder through the suction tube.

[0022] In the present invention, the beneficial effects of the device for realizing power transmission cut-off and input are:

[0023] The rotating arm of this scheme can be driven by a pull wire, a push rod, or an electromagnetic push rod to make the rotating arm rotate, and then make an axial movement after the movable inclined block rotates. When the movable inclined block is driven to move axially outside, the internal transmission sleeve is driven to move axially through the bearing. At the same time, the internal transmission sleeve can be driven to rotate radially by the power shaft. An electromagnet is arranged on the outer ring of the movable inclined block. When the electromagnet is energized, a magnetic attraction is generated, which produces a magnetic attraction effect on the suction circle on the movable inclined block. The movable inclined block overcomes the elastic force of the central annular compression spring and makes an upward axial movement, thereby realizing the power transmission function. On the contrary, when the electromagnet loses power, the elastic force of the annular compression spring prompts the movable block to cut off the power transmission. When the transmission sleeve moves under the drive of the movable inclined block, the elastic force of the compression spring exerts an axial thrust on the transmission sleeve. Under this thrust, the axial movement of the transmission sleeve starts smoothly without fluctuations and unstable movement.

[0024] When the clutch transmission of this scheme is working, the output shaft rotates to drive the fan blades, and the external air enters the interior of the shell to blow and cool down. The output shaft drives the rotating rod to rotate through the second bevel gear and the first bevel gear, and the rotating rod drives the spiral blades to rotate in the cylinder. The coolant enters the cylinder through the suction pipe and then enters the cooling return pipe. Since the cooling return pipe is spirally arranged on the inner wall of the shell, the cooling area is increased, and the cooling effect is improved. The cooling effect can be further improved by cooling the coolant through the semiconductor refrigerator. The cooling return pipe circulates the coolant into the cooling box, and the coolant can be repeatedly recycled.

[0025] The present invention facilitates transmission connection of the clutch and transmission cutting and connection work. Through the cooperation of fans, refrigeration and coolant circulation, the clutch can be effectively cooled, the cooling effect is improved, and the service life is prevented from being affected by high-temperature operation.

A concave claw 41 is provided on the inner side of the power shaft 4. The protruding claw 21 matches with the concave claw 41. The concave claw 41 is evenly distributed inside the power shaft 4. The concave claw 41 can be divided into multiple groups, such as 8 groups. The larger the inner diameter of the power shaft, the more groups there can be. The concave claw 41 of the power shaft forms a matching relationship with the protruding claw 21 of the transmission sleeve 2.

[0048] A fan mechanism is rotatably disposed inside the housing 11 to cool the entire system;

[0049] The cooling mechanism is arranged on the housing 11 and is used for cooling the air. A control box 13 is arranged on the outer side of the housing 11 , and a push switch 14 is arranged on the control box 13 .

[0050] Reference Figure 4 In this embodiment, a compression spring 7 is provided on the outer side of the output shaft 5, the top of the compression spring 7 is fixedly installed on the inner side of the embedded block 3, and the bottom of the compression spring 7 is fixedly installed on the bottom inner wall of the transmission sleeve 2. The compression spring 7 is an annular structure, and a pulley 6 is fixedly installed on the outer side of the power shaft 4.

[0051] Reference Figure 3 In this embodiment, a plurality of ribs 103 are evenly distributed on the circumference of the movable inclined block 1, and the bottom surface of the rib 103 is made into a first spiral surface 104.

[0052] Reference Figure 3 In this embodiment, a rotating arm 102 is arranged on the circumference of the movable inclined block 1. The rotating arm 102 can be driven by a pull wire, a push rod, or an electromagnetic push rod to make the rotating arm 102 rotate, thereby causing the movable inclined block 1 to rotate and then move axially.

[0053] Reference Figure 8 In this embodiment, an electromagnet 9 is arranged on the outer ring of the moving inclined block 1, and a suction circle 106 is arranged on the top of the moving inclined block 1. When the electromagnet 9 is energized, it attracts the suction circle 106, generating a magnetic attraction, and the moving inclined block 1 overcomes the elastic force of the central compression spring 7 and moves upward axially, thereby realizing the power transmission function. On the contrary, when the electromagnet loses power, the elastic force of the compression spring 7 prompts the moving block to cut off the power transmission. The transmission sleeve 2 is arranged with a compression spring 7 inside. When the transmission sleeve moves under the drive of the moving inclined block 1, the elastic force of the compression spring 7 exerts an axial thrust on the transmission sleeve 2. Under this thrust, the axial movement of the transmission sleeve 2 starts smoothly, and no fluctuations or unstable movement occur.

[0055] Reference Fig.11In this embodiment, fan blades 19 are installed on the outside of the fan shaft 18, and a plurality of air inlet holes 111 are opened at the bottom of the housing 11; the output shaft 5 rotates to drive the fan blades 19, and the external air enters the interior of the housing 11 for blowing and cooling.

[0056] Reference Fig. 9 , Fig.10 In this embodiment, the cooling mechanism includes a cooling box 15, which is welded to the outer side of the shell 11. A liquid filling port 151 is provided on the top of the cooling box 15. Cooling liquid is provided in the cooling box 15. A semiconductor refrigerator 16 is embedded in the outer side of the cooling box 15. The cooling surface of the semiconductor refrigerator 16 is located in the cooling box 15, and the heat dissipation surface of the semiconductor refrigerator 16 is located on the outer side. A protective net 161 is installed on the outer side of the cooling box 15, and the heat dissipation surface of the semiconductor refrigerator 16 is located in the protective net 161. By cooling the coolant with the semiconductor refrigerator 16, the cooling effect can be further improved.

[0057] Reference Figure 12-Figure 15 In this embodiment, a cylinder 120 is installed on the inner wall of the outer shell 11, and a cooling reflux pipe 123 and a liquid suction pipe 121 are installed on the outer side of the cylinder 120. The cooling reflux pipe 123 and the liquid suction pipe 121 are located on different sides. The other end of the cooling reflux pipe 123 is connected to the top of the cooling box 15, and the other end of the liquid suction pipe 121 is connected to the bottom side of the cooling box 15. A water inlet 128 and a water outlet 129 are provided on the outer side of the cylinder 120. The water inlet 128 is welded to the liquid suction pipe 121, and the water outlet 129 is connected to the cooling reflux pipe 123.

[0058] Reference Figure 12-16 In this embodiment, a rotating rod 126 is rotatably installed in the cylinder 120 through a sealed bearing, and a spiral blade 127 is provided on the outer side of the rotating rod 126 located inside the cylinder 120. The spiral blade 127 is slidably connected to the inner wall of the cylinder 120, and a first bevel gear 124 is fixedly installed on the outer end of the rotating rod 126. A second bevel gear 125 is sleeved on the outer side of the fan shaft 18, and the first bevel gear 124 is meshed with the second bevel gear 125; the output shaft 5 drives the rotating rod 126 to rotate through the second bevel gear 125 and the first bevel gear 124, and the rotating rod 126 drives the spiral blade 127 to rotate in the cylinder 120, and the coolant enters the cylinder 120 through the suction pipe 121.

[0059] Working principle: when in use, the power supply and PLC controller can be turned on to control the electrical appliances. The prior art will not be elaborated here. The power is transmitted by the connected pulley 6, and mechanical structures such as gears and sprockets can also be used to transmit power. The rotating arm 102 can be driven by a pull wire, a push rod, or an electromagnetic push rod to make the rotating arm 102 rotate, so as to cause the moving inclined block 1 to rotate and then move axially. When the moving inclined block 1 is driven externally to move axially, the internal transmission sleeve 2 is driven axially through the bearing 101. At the same time, the internal transmission sleeve 2 can be driven by the power shaft 4 to rotate radially. An electromagnet 9 is arranged on the outer ring of the moving inclined block 1. When the electromagnet is energized, a magnetic attraction is generated, which produces a magnetic attraction effect on the suction circle 106 on the moving inclined block 1. The moving inclined block 1 overcomes the elastic force of the central annular compression spring 7 and moves upward axially, thereby realizing the power transmission function. On the contrary, when the electromagnet loses power, the elastic force of the annular compression spring 7 prompts the moving block to cut off the power transmission. When the transmission sleeve moves driven by the moving inclined block 1, the elastic force of the compression spring 7 exerts an axial thrust on the transmission sleeve 2. Under the action of this thrust, the axial movement of the transmission sleeve 2 starts smoothly without fluctuations or unstable movement. At the same time, when the transmission sleeve has no external axial force, the compression spring 7 starts the reset action. When the clutch transmission is working, the output shaft 5 rotates to drive the fan blades 19, and the external air enters the interior of the shell 11 for blowing and cooling. The output shaft 5 drives the rotating rod 126 to rotate through the second bevel gear 125 and the first bevel gear 124, and the rotating rod 126 drives the spiral blades 127 to rotate in the cylinder 120. The coolant enters the cylinder 120 through the suction pipe 121, and then enters the cooling return pipe 123. Since the cooling return pipe 123 is spirally arranged on the inner wall of the shell 11, the cooling area is increased, and the cooling effect is improved. The cooling effect can be further improved by cooling the coolant with the semiconductor refrigerator 16. The cooling return pipe 123 circulates the coolant into the cooling box 15, and the coolant can be repeatedly recycled.
