[0037] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0038] The timing gear 200 is interference-connected to one end of the crankshaft 100 to transmit the power of the crankshaft 100. When the timing gear 200 and other gears have a tooth-smashing phenomenon, the timing gear 200 needs to be replaced.

[0039] However, the timing gear 200 is difficult to remove due to the interference fit, and destructive removal methods such as cutting may easily damage the surface of the crankshaft 100 .

[0040] In order to solve the technical problem that the surface of the crankshaft 100 is easily damaged when the timing gear 200 is disassembled, the first embodiment of the present application provides a disassembly device, see Figure 1 , Figure 2 , Figure 3 and Figure 4 , the disassembly equipment is used to separate the crankshaft 100 and the timing gear 200, see Figure 5 and Figure 6 The crankshaft 100 includes a connecting portion 110 and a main body 120 extending along a first direction X, and the timing gear 200 is sleeved on the connecting portion 110; the disassembly equipment includes a heating device 300 and a moving device 400, and the heating device 300 can be connected with the timing gear 200 to heat the timing gear 200; the moving device 400 includes a connecting component 410 and an actuator 420, the connecting component 410 is used to connect with the timing gear 200, and the actuator 420 is connected to the connecting component 410, and the actuator 420 is used to drive the connecting component 410 to move along the first direction X in a direction away from the main body 120, so that the timing gear 200 moves relative to the connecting portion 110, and the first direction X is the direction indicated by the X arrow in the accompanying drawings.

[0041] In some embodiments, see Figure 7 and Figure 8 The heating device 300 is a coil wound by a resistance wire, which converts electrical energy into heat energy to heat the timing gear 200.

[0042] In some embodiments, the actuator 420 is one of an electric cylinder, a hydraulic cylinder, and a pneumatic cylinder. In the above embodiment, the timing gear 200 is heated by the heating device 300. Since the materials of the timing gear 200 and the crankshaft 100 are different, the deformation degrees of the two are different. When the timing gear 200 is sufficiently deformed, the actuator 420 moves the connecting assembly 410 connected to the timing gear 200 along the first direction X and away from the main body 120, so that the timing gear 200 moves along the first direction X in a direction away from the main body 120 until it is separated from the crankshaft 100. During disassembly, the disassembly equipment will not contact the surface of the crankshaft 100, and the crankshaft 100 will not be removed until it is deformed to a certain extent, that is, the surface of the crankshaft 100 will not be damaged during the disassembly process.

[0043] In some embodiments, see Figure 5The timing gear 200 has an oil hole 210 ; the heating device 300 further includes a temperature detection unit 330 , which can be disposed in the oil hole 210 to detect the temperature of the timing gear 200 .

[0044] In some embodiments, the temperature detection unit 330 is a temperature sensor.

[0045] In some embodiments, the timing gear 200 does not have the oil hole 210 , and the temperature detection unit 330 is attached to the surface of the timing gear 200 to detect the temperature of the timing gear 200 .

[0046] In the above embodiment, by arranging the temperature detection unit 330 in the oil hole 210, the temperature detection unit 330 can detect the temperature of the timing gear 200 from the inside of the timing gear 200, and the obtained temperature is more accurate, so that the operator can choose the timing of using the actuator 420 to drive the connecting component 410 according to the temperature. Obtaining a more accurate temperature can move the timing gear 200 after the timing gear 200 has generated sufficient deformation, avoid moving the timing gear 200 in advance, and reduce the possibility of the timing gear 200 scratching the surface of the crankshaft 100.

[0047] In some embodiments, please refer again to Figure 1 , Figure 2 , Figure 7 and Figure 8 The mobile device 400 also includes a driving component 430 , which is connected to the execution component 420 ; the temperature detection unit 330 is connected to the driving component 430 , and can output a signal to the driving component 430 so that the driving component 430 drives the execution component 420 .

[0048] In some embodiments, the driving component 430 is one or more of a hydraulic pump, an air pump, or an electronic control device capable of driving the actuator component 420 .

[0049] In some embodiments, the temperature detection unit 330 is connected to the drive assembly 430 in communication, so that the drive assembly 430 can receive the temperature signal of the timing gear 200. In some embodiments, the drive assembly 430 is provided with a preset temperature value, and when the timing gear 200 reaches the preset temperature value, the temperature detection unit 330 outputs a signal to the drive assembly 430, and the drive assembly 430 drives the actuator 420 to act after receiving the signal, so as to avoid premature movement of the timing gear 200 to damage the crankshaft 100.

[0050] In some embodiments, please refer again to Figure 1 and Figure 2The actuator component 420 includes a first moving member 421 and a second moving member 422, the first moving member 421 and the second moving member 422 are connected, the first moving member 421 can be abutted against the end surface of the connecting portion 110 along the first direction X, the second moving member 422 is connected to the connecting component 410, and the first moving member 421 can move relative to the second moving member 422 along the first direction X to drive the connecting component 410.

[0051] In some embodiments, the actuator 420 is a hydraulic cylinder, the first moving member 421 is a piston rod, and the second moving member 422 is a cylinder body.

[0052] See also Figure 5 and Figure 8 In some embodiments, a positioning groove is provided at the end of the connecting portion 110 away from the main body portion 120, and the end of the first movable member 421 in the actuator 420 can be embedded in the positioning groove to achieve centering of the actuator 420 and the crankshaft 100 along a direction perpendicular to the first direction X.

[0053] In some embodiments, the first moving member 421 is a piston rod extending along the first direction X. In the above embodiments, only the first moving member 421 of the entire disassembly device is connected to the crankshaft 100 and is connected to the end surface of the body 120 , so that the surface of the crankshaft 100 will not be damaged.

[0054] In addition, since the disassembly device is only connected to the end face of the crankshaft 100, there is no need to open the engine block when using the disassembly device to disassemble the timing gear 200. The timing gear 200 arranged outside the engine block can be directly disassembled, which reduces the difficulty of disassembling the timing gear 200.

[0055] In some embodiments, please refer again to Figure 2 , Figure 7 and Figure 8 The connecting component 410 includes a base 411 and a clamp 412 , the base 411 is connected to the actuator 420 ; one end of the clamp 412 along the first direction X is connected to the base 411 , and the other end of the clamp 412 can be connected to the timing gear 200 .

[0056] In some embodiments, the base 411 is connected to a side of the actuator 420 away from the crankshaft 100 along the first direction X, and the base 411 is connected to the second movable member 422. When the second movable member 422 moves away from the crankshaft 100 along the first direction X, the base 411 also moves along the first direction X away from the crankshaft 100 following the second movable member 422.

[0057] In other embodiments, the base 411 is connected to a side of the actuator 420 close to the crankshaft 100 along the first direction X, and the base 411 is connected to the second movable member 422. When the second movable member 422 moves along the first direction X away from the crankshaft 100, the base 411 also follows the second movable member 422 to move along the first direction X away from the crankshaft 100.

[0058] In the above embodiment, the clamp 412 is used to connect the base 411 and the timing gear 200, and the base 411 is used to connect the clamp 412 and the actuator 420, so that the timing gear 200 can follow the second moving member 422 to move relative to the connecting part 110 along the first direction X, so that the timing gear 200 can be disengaged from the connecting part 110.

[0059] In some embodiments, see Figure 5 and Figure 6 The timing gear 200 has a first surface 220 and a second surface 230, the first surface 220 is opposite to the second surface 230, and the second surface 230 is toward the main body 120; the clamp 412 includes a connecting rod 4121 and a limit block 4122 that are connected to each other, the connecting rod 4121 extends along the first direction X, one end of the connecting rod 4121 along the first direction X is connected to the base 411, and the limit block 4122 is connected to the other end, the limit block 4122 has a connecting surface 4123, the connecting surface 4123 is toward the base 411 along the first direction X, and the connecting surface 4123 can be connected to the second surface 230.

[0060] Since the disassembly device only needs to drive the timing gear 200 to move in the first direction X in the direction away from the main body 120, the clamping jaw 412 only needs to remain relatively stationary with the timing gear 200 in one degree of freedom. In the above embodiment, the connecting surface 4123 is connected to the surface of the timing gear 200 close to the main body 120, that is, the second surface 230, and the clamping jaw 412 with the connecting surface 4123 can provide the timing gear 200 with a thrust away from the main body 120 along the first direction X, so that the timing gear 200 has a tendency to move away from the main body 120 along the first direction X.

[0061] In some embodiments, please refer again to Figure 1 , Figure 2 , Figure 7 and Figure 8 The clamping jaw 412 can rotate relative to the base 411 so that the other end of the clamping jaw 412 can approach or move away from the timing gear 200 along a direction perpendicular to the first direction X.

[0062] In some embodiments, one end of the clamp 412 is hinged to the base 411, and the mobile device 400 also includes a connecting pin. The clamp 412 has a first pin hole, and the base 411 has a second pin hole. The connecting pin is passed through the first pin hole and the second pin hole so that the clamp 412 can rotate relative to the base 411, and the axis of the connecting pin is perpendicular to the first direction X.

[0063] In the above embodiment, since the clamp 412 and the base 411 can rotate, when the moving device 400 is installed on the crankshaft 100, it is only necessary to rotate the clamp 412 so that the clamp 412 rotates in a direction perpendicular to the first direction X toward a direction away from the crankshaft 100. After the actuator 420 abuts against the crankshaft 100, the position of the clamp 412 is restored so that the limit block 4122 of the clamp 412 is connected to the timing gear 200, which can avoid the interference between the limit block 4122 of the clamp 412 and the timing gear 200, thereby causing the moving device 400 to be unable to move in the first direction X, and the first moving member 421 cannot abut against the end face of the connecting portion 110.

[0064] In some embodiments, the disassembly device further includes a limiting assembly, which is respectively connected to the clamping jaw 412 and the base 411 to limit the rotation of the clamping jaw 412 relative to the base 411 .

[0065] In some embodiments, the mobile device 400 also includes a limit pin, the clamp 412 has a third pin hole extending in the same direction as the first pin hole, and the base 411 has a fourth pin hole extending in the same direction as the second pin hole. The limit pin can be inserted into the third pin hole and the fourth pin hole to act simultaneously with the connecting pin to limit the rotation of the clamp 412 relative to the base 411.

[0066] In the above embodiment, since the limit pin can limit the relative rotation between the clamp 412 and the base 411, when the clamp 412 is connected to the timing gear 200, even if the clamp 412 is affected by gravity, gravity will not cause the clamp 412 to separate from the timing gear 200, thereby reducing the difficulty of using the disassembly equipment.

[0067] In some embodiments, please refer again to Figure 1 , Figure 2 , Figure 7 and Figure 8 The connecting assembly 410 includes a plurality of clamps 412 , which can rotate relative to the base 411 to change the maximum distance between the other ends of any two clamps 412 in a direction perpendicular to the first direction X. That is, the opening size of the plurality of clamps 412 away from one end of the base 411 is changed.

[0068] It is understandable that the plurality of clamps 412 can improve the mechanical properties of the mobile device 400, reduce the possibility of failure at the connection between the connecting rod 4121 and the stop block 4122 when the actuator 420 is in motion, and improve the reliability of the disassembly device. In addition, the plurality of clamps 412 can rotate relative to the base 411 to facilitate the connection between the mobile device 400 and the timing gear 200 and the crankshaft 100.

[0069] In some embodiments, the disassembly device further includes a connector, which is connected to the mobile device 400 , and is used to connect to a carrying device to prevent the mobile device 400 from falling.

[0070] During the disassembly process, since the first moving member 421 moves along the first direction X in a direction away from the main body 120, the center of gravity of the moving device 400 also moves along the first direction X in a direction away from the main body 120. In the above embodiment, by providing a connecting member to connect the supporting device, the moving device 400 can be prevented from falling during the disassembly of the timing gear 200.

[0071] In some embodiments, the carrying device is a vehicle.

[0072] In some embodiments, the connecting member is a lifting lug connected to the base 411, and the lifting lug can be connected to the lifting ring of the crane to prevent the disassembly equipment from falling to the ground, thereby improving the safety of the disassembly equipment.

[0073] In some embodiments, see Figure 2 , Figure 7 and Figure 8 The heating device 300 has a receiving cavity 310 , which penetrates the heating device 300 along the first direction X. The heating device 300 has an inner wall 320 , which is used to enclose the receiving cavity 310 , and the inner wall 320 can contact the timing gear 200 .

[0074] In the above embodiment, when the timing gear is disassembled, the heating device 300 is sleeved on the timing gear 200 so that the timing gear 200 is located in the accommodating cavity 310, and the inner wall 320 is in contact with the timing gear 200, and heat is transferred to the timing gear 200 to heat the timing gear 200.

[0075] In the above embodiment, by providing a accommodating cavity 310 that can accommodate the timing gear 200, the contact area between the heating device 300 and the timing gear 200 can be increased, thereby improving the heating efficiency of the timing gear 200, so that the timing gear 200 can reach the preset temperature as soon as possible to increase the disassembly speed.

[0076] The following is the action process of disassembling the timing gear 200 by the disassembly device in the embodiment of the present application:

[0077] 1. The heating device 300 is sleeved on the timing gear so that the timing gear 200 is located in the accommodating cavity 310;

[0078] 2. The temperature detection unit 330 is inserted into the oil hole 210;

[0079] 3. Rotate the plurality of clamping jaws 412 so that the plurality of clamping jaws 412 are opened;

[0080] 4. The first moving member 421 is abutted against the end surface of the connecting portion 110;

[0081] 5. Rotate the plurality of clamping jaws 412 so that the connection surfaces 4123 of the plurality of clamping jaws 412 are respectively connected to the second surface 230 of the timing gear 200;

[0082] 6. Use a limit assembly to limit the rotation of the plurality of clamping jaws 412;

[0083] 7. Start the heating device 300 to heat the timing gear 200;

[0084] 8. When the preset temperature is reached, the temperature detection unit 330 transmits a signal to the driving component 430, and the driving component 430 drives the execution component 420;

[0085] 9. The second moving member 422 moves along the first direction X in a direction away from the main body 120 , and the connecting assembly 410 drives the timing gear 200 to move along the first direction X in a direction away from the main body 120 ;

[0086] 10. The timing gear 200 is disengaged from the crankshaft 100;

[0087] 11. Remove the disassembly equipment and the disassembly is complete.

[0088] Accordingly, the present application also provides a maintenance device, including a disassembly device as in any one of the above embodiments. Since the disassembly device is only connected to the end face of the crankshaft 100, the surface of the crankshaft 100 will not be damaged, and there is no need to disassemble the cylinder block of the engine, which reduces the difficulty of disassembling the timing gear 200 while ensuring that the surface of the crankshaft 100 is not damaged. The maintenance device is used to repair the engine.
