Description

Technical Field

[0001] This invention belongs to the field of permanent magnet speed regulator technology, specifically, it relates to a movable support for a permanent magnet speed regulator and a permanent magnet speed regulator. Background Technology

[0002] A permanent magnet speed controller is an advanced transmission device that uses non-contact force between magnets to transmit torque. It is widely used in speed regulation and energy saving of equipment such as fans and pumps. It mainly consists of two parts: a conductor rotor (usually a copper or aluminum disc) connected to the motor, and a permanent magnet rotor (a disc embedded with permanent magnets) connected to the load. By adjusting the air gap between the two rotors, the magnetic coupling strength can be changed, thereby achieving stepless adjustment of the load speed while keeping the motor speed constant.

[0003] To facilitate adjustment of the distance between the permanent magnet rotor and the conductor rotor, a movable support structure is often used to adjust their relative positions, thereby achieving speed regulation. Existing technologies for this type of structure typically include a lead screw and nut pair driven by a motor. The servo motor drives the lead screw to rotate, which in turn drives the mating nut to produce axial linear motion. This nut is fixedly connected to the output shaft or housing of the permanent magnet rotor via a rigid flange, thus converting the linear motion of the nut into axial displacement of the permanent magnet rotor, achieving adjustment of the air gap and speed. However, this type of structure often uses bolts... The connection between the permanent magnet rotor and the ball screw is typically secured by dozens of high-strength bolts. When core components of the ball screw module (such as the screw, nut, or bearing) wear out due to long-term use and require replacement, the permanent magnet rotor must be separated from the ball screw structure. Maintenance personnel must disassemble all these bolts one by one, a tedious and laborious process. If the bolts become stuck due to corrosion or interference fit, the disassembly difficulty and time will be further increased, leading to prolonged equipment downtime and significant production losses. Furthermore, once the bolt connection is loosened, the original precision alignment is destroyed. Reinstallation is equivalent to performing a high-precision shaft alignment operation again. This process is highly dependent on the experience and skill level of the maintenance personnel, which can easily lead to parallelism errors between the permanent magnet rotor and the conductor rotor. This can cause a sharp increase in equipment vibration and noise, shorten the life of the connecting parts, and may even cause more serious secondary failures due to improper installation.

[0004] Therefore, existing technologies need further improvement and enhancement. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a movable support for a permanent magnet speed regulator and a permanent magnet speed regulator.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: This application provides a movable support for a permanent magnet speed controller, comprising: an actuating component: the output end of which is connected to the permanent magnet speed controller and drives the permanent magnet rotor to move; a quick-release component: which is detachably disposed between the permanent magnet speed controller and the actuating component, including a connector disposed on the permanent magnet speed controller and a locking head disposed on the actuating component; and a support body: which supports the actuating component and the permanent magnet speed controller.

[0007] In a preferred embodiment of this application, the connector is interference-fitted with or integrally formed with the end of the permanent magnet rotor of the permanent magnet speed controller, and the connector sidewall is provided with a plug interface around its circumference.

[0008] In a preferred embodiment of this application, the locking head includes a housing and a pin portion disposed on the inner wall of the housing, the pin portion being detachably connected to the connector.

[0009] In a preferred embodiment of this application, the latch includes an oil cavity and a locking pin, with the locking pin slidably positioned within the oil cavity.

[0010] In a preferred embodiment of this application, the movable support further includes a hydraulic drive assembly, comprising: a hydraulic power unit disposed at the bottom of the support body for outputting hydraulic power; an annular cylinder connected to the pin portion, having an internal oil passage communicating with the oil chamber, receiving oil from the hydraulic power unit and pushing the locking pin to move; and a hydraulic oil pipe for connecting the hydraulic power unit and the annular cylinder.

[0011] In a preferred embodiment of this application, the side of the plug-in interface is a conical surface with a cone angle between 15° and 30°, and the locking pin is adapted to the plug-in interface.

[0012] In a preferred embodiment of this application, the pin portion further includes an elastic element, one end of which is connected to the end of the locking pin and the other end is connected to the inner wall of the annular cylinder, so as to provide a radially outward restoring force for the locking pin.

[0013] In a preferred embodiment of this application, the actuation component includes a power component, a lead screw, a sliding block, and a protective shell that encloses the lead screw and the sliding block. The power component drives the lead screw to rotate, and the sliding block moves along the length of the lead screw.

[0014] In a preferred embodiment of this application, the top of the sliding block is connected to the locking head, the connector is placed at the bottom of the permanent magnet rotor, and the locking head slides relative to the outer wall of the connector.

[0015] This application also provides a permanent magnet speed regulator, applied to a movable support for a permanent magnet speed regulator, comprising: an input section for providing power to the permanent magnet speed regulator; a conductor rotor connected to the input section for transmitting power; a permanent magnet rotor magnetically coupled to the conductor rotor and connected to the connector; an output shaft that does not directly contact the lead screw and outputs power; and a mounting bracket detachably mounted on the surface of the support body.

[0016] After adopting the above technical solution, the movable support and permanent magnet speed regulator provided by the present invention have the following beneficial effects compared with the prior art.

[0017] 1. This application provides a movable support for a permanent magnet speed controller. By setting an action component, the permanent magnet rotor of the permanent magnet speed controller is driven to move, thereby adjusting the air gap of the permanent magnet speed controller and realizing speed regulation. Furthermore, by placing a quick-release component, compared with the traditional bolt connection, this application adopts a combination of a connector head and a locking head, which improves the efficiency of disassembly and assembly and reduces the errors that are easy to occur during reassembly, ensuring the accuracy of the equipment when it is disassembled and reassembled.

[0018] 2. As a preferred embodiment of this application, by setting the connector and the permanent magnet rotor to be integrally formed, the application can facilitate processing and improve the reliability of use. The interference fit between the connector and the permanent magnet rotor can reduce processing costs while ensuring connection strength. Furthermore, the application improves the efficiency of disassembly and assembly through the cooperation of the plug-in interface and the locking pin.

[0019] 3. As a preferred embodiment of this application, this application uses an additional hydraulic power unit as the power source for the locking pin in the latch section. Compared with complex mechanical control methods and the need to set up multiple motor structures to control the movement of multiple locking pins, the hydraulic drive method is not only simpler in structure and saves installation space, making the structure more compact, but also has better synchronization. It can ensure that multiple locking pins lock synchronously as much as possible. Moreover, once the system is locked, "hydraulic self-locking" can be achieved simply by cutting off the oil circuit through a reversing valve. At this time, the hydraulic oil sealed in the oil circuit can reliably maintain the locking force. Not only is the structure simpler, but it can also realize one-button pressure relief and pressurization, making disassembly and assembly more convenient. It eliminates the cumbersome process of disassembling and assembling multiple bolts and controlling motors, further accelerating the efficiency of disassembly and assembly.

[0020] 4. As a preferred embodiment of this application, by setting a conical insertion interface and a locking pin, this application can facilitate the smooth entry of the locking pin into the insertion interface through the inclined side. On the other hand, the inclined conical structure has a stronger biting force after locking compared to the horizontal structure, making the connection between the connector and the locking head tighter. Furthermore, by setting an elastic element, this application can enable the locking pin to be quickly withdrawn from the insertion interface by the reset pulling force of the elastic element after the hydraulic oil is unloaded during disassembly, further improving the efficiency of disassembly and assembly.

[0021] 5. As a preferred embodiment of this application, this application sets a locking head on the top of the sliding block of the lead screw structure, which makes the structure more compact and convenient for maintenance and disassembly. On the other hand, it works with the connecting head structure set at the bottom of the permanent magnet rotor housing to drive the permanent magnet rotor to move. Of course, setting the sliding block at the bottom can also avoid the permanent magnet speed regulator above, making it convenient to assemble and connect with the lower hydraulic mechanism, further improving the convenience of maintenance.

[0024] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] like Figures 1 to 8 As shown, the present invention provides a technical solution: This application provides a movable support for a permanent magnet speed regulator 4, including: an actuation component 1: the output end is connected to the permanent magnet speed regulator 4, driving the permanent magnet rotor 43 to move; a quick-release component 2: detachably disposed between the permanent magnet speed regulator 4 and the actuation component 1, including a connector 21 disposed on the permanent magnet speed regulator 4 and a locking head 22 disposed on the actuation component 1; and a support body 3: supporting the actuation component 1 and the permanent magnet speed regulator 4.

[0030] Among them, such as Figure 1 and Figure 3 As shown, the support body 3 can adopt a plate-shaped support structure to support the entire permanent magnet speed controller 4, as well as the action component 1 and quick-release component 2, providing sufficient placement space for each structure.

[0031] In addition, from Figure 2 and Figure 4 As can be seen, the connector 21 is interference-fitted with or integrally formed with the end of the permanent magnet rotor 43 of the permanent magnet speed controller 4, and the connector 21 has a circumferentially arranged insertion interface 211 on the side wall. To facilitate structural description, an interference fit can be used between the permanent magnet rotor 43 and the connector 21 to reduce processing costs. Since the permanent magnet rotor 43 structure does not require replacement, an interference fit is used to achieve a connection with no relative movement, high rigidity, and high coaxiality. For the connection method, the connector 21 can be heated using a heating furnace, induction heater, or oil bath to uniformly heat the connector 21 to a calculated temperature (usually 200-300°C higher than the ambient temperature, depending on the interference amount). Quickly clean the outer shell or outer surface of the permanent magnet rotor 43 and the mating surface of the inner wall of the connector 21 to ensure there is no grease or dust. Remove the heated connector 21 from the furnace, quickly and accurately align it, and fit it onto the outer wall of the permanent magnet rotor 43, usually positioning it against a preset shoulder. Allow it to cool naturally to room temperature. During the cooling process, the connector 21 will tightly "hold" the permanent magnet rotor 43, achieving an interference fit.

[0032] Furthermore, the locking head 22 includes a housing 221 and a pin portion 222 disposed on the inner wall of the housing 221, the pin portion 222 being detachably connected to the connector head 21. The pin portion 222 includes an oil cavity 223 and a locking pin 224, the locking pin 224 being slidably disposed within the oil cavity 223.

[0033] Specifically, such as Figure 5 and Figure 6 As shown, the connector 21 can adopt a cylindrical structure similar to a connecting hub, and be integrated with the permanent magnet rotor 43. Multiple insertion ports 211 are evenly distributed in a ring on its surface for engaging with the locking pins 224 of the insertion pin portion 222. Regarding the structure of the locking head 22, the enclosure 221 allows the locking head 22 to be fitted onto the surface of the connector 21, and the locking pins 224 on the inner wall are inserted into the insertion ports 211 to complete the assembly and positioning of the connector 21 and the locking head 22. Furthermore, to improve the sealing effect, a hinged arc-shaped baffle or a sealing ring can be provided at the head end of the enclosure 221 to further enhance the tightness and sealing between the connector 21 and the locking head 22.

[0034] Of course, in order to ensure the operation of the locking pin 224 and to prevent the protruding locking pin 224 from affecting the operation of the locking head 22 on the connector 21 during the initial assembly of the connector 21 and the locking head 22, the inner wall of the housing 221 of the locking head 22 should be thick enough to ensure that the locking pin 224 can be placed inside the housing 221 when locking is not required. In addition, in order to ensure the smooth and stable operation of the locking pin 224, the pin part 222 is also provided with an oil cavity 223 structure. The oil cavity 223 should extend into the inner wall of the housing 221, and the locking pin 224 moves along the vertical groove of the oil cavity 223 to ensure the normal use of the locking pin 224.

[0035] In a preferred embodiment, the movable support further includes a hydraulic drive assembly 5, comprising: a hydraulic power unit 51: disposed at the bottom of the support body 3 for outputting hydraulic power; an annular cylinder 52: connected to the pin portion 222, having an oil passage 521 communicating with the oil chamber 223, receiving oil from the hydraulic power unit 51 and pushing the locking pin 224 to move; and a hydraulic oil pipe 53: used to connect the hydraulic power unit 51 and the annular cylinder 52.

[0036] It is understandable that the oil chamber 223 structure provided inside the housing 221 of the locking head 22 is connected to the annular cylinder 52, so that oil can be transported from the hydraulic power unit 51 along the oil passage 521 in the annular cylinder 52 to the oil chamber 223, pushing the locking pin 224 to move. Furthermore, for the structure of the annular cylinder 52, the number and installation position of its oil passages 521 correspond to the positions of the oil chambers 223 and the locking pin 224, and each oil passage 521 should be connected to ensure that hydraulic oil can enter each oil chamber 223 synchronously for driving. Moreover, for the oil chamber 223 structure of the pin part 222, each oil chamber 223 can also be provided with an oil passage 521 structure, which corresponds to the oil passage 521 structure of the annular cylinder 52, thereby improving the working efficiency of the hydraulic oil. Of course, each oil chamber 223 can also be set as a separate oil chamber 223, corresponding to the oil passage 521 of the annular cylinder 52, which can also achieve the working effect of the hydraulic oil.

[0037] Of course, in order to improve the reliability of use, reduce costs, and ensure the synchronization of hydraulic transmission and locking pin 224 action, the annular cylinder 52 and the housing 221 can be integrated into one structure. That is, the outer edge of the housing 221 has a protruding ring structure to transfer and carry the oil, and smoothly transport the oil through the oil chamber 223 to the locking pin 224, pushing the locking pin 224 to act. Alternatively, a separate arrangement can be adopted, with the oil chamber 223 and the annular cylinder 52 connected by a hydraulic oil pipe 53, which can also realize the transmission and transportation of hydraulic oil.

[0038] For the hydraulic oil pipe 53, since the hydraulic drive component 5 needs to drive the permanent magnet rotor 43 to adjust the air gap of the permanent magnet speed regulator 4 in the horizontal direction, the hydraulic oil pipe 53 needs to be set to have a certain degree of flexibility, such as using steel wire braiding or winding high-pressure hose, to facilitate the movement of the permanent magnet rotor 43. In addition, the length of the hose must be greater than the maximum stroke of the moving module and leave sufficient margin so that it is always in a natural and relaxed bending state during the movement, rather than being straightened or excessively bent.

[0039] In a preferred embodiment of this application, the side of the insertion interface 211 is a conical surface with a cone angle between 15° and 30°. The locking pin 224 is adapted to the insertion interface 211. It is understood that the shape of the locking pin 224 is similar to that of the insertion interface 211, and it also adopts a beveled structure. Furthermore, the locking pin 224 is a conical structure, which further facilitates the insertion of the locking pin 224 into the insertion interface 211 and improves the tightness of the fit between the two. The contact stress is evenly distributed on the entire conical ring surface, reducing wear, and the continuous surface is more conducive to forming a uniform contact band, improving the sealing effect.

[0040] Furthermore, the sliding groove structure provided in the oil cavity 223 also adopts a conical arc structure with a similar tilt angle to the locking pin 224 to ensure the stability of the locking pin 224 when it moves. The pin part 222 also includes an elastic element 23. One end of the elastic element 23 is connected to the end of the locking pin 224, and the other end is connected to the inner wall of the annular oil cylinder 52 to provide a radially outward restoring force for the locking pin 224.

[0041] Optionally, the end of the locking pin 224 may be provided with an annular groove, and the elastic element 23, which is a return spring, is sleeved inside the annular groove. A protruding structure may be provided on the top wall of the oil passage 521 of the annular cylinder 52, which is connected to the oil cavity 223. The protrusion is connected to the other end of the elastic element 23. During normal use, oil is transported to the oil cavity 223 via the hydraulic power unit 51 along the annular cylinder 52, pushing the locking pin 224. At this time, the thrust of the hydraulic oil is greater than the tension of the elastic element 23, thus pushing the locking pin 224 gradually into the insertion interface 211 along the slide groove until the locking pin 224 is in contact with the insertion interface 211. 1. During assembly, the hydraulic power unit 51 locks the hydraulic oil, locking the connection between the locking pin 224 and the insertion interface 211. When it is necessary to inspect the actuating component 1 or the permanent magnet speed regulator 4, the hydraulic oil can be released through the hydraulic drive component 5, thereby gradually reducing the hydraulic oil thrust pressing the locking pin 224. At this time, under the pulling force of the elastic element 23, the locking pin 224 quickly exits the insertion interface 211 and gradually returns to the initial position along the slide groove. In this way, the meshing connection between the connector 21 and the locking head 22 is canceled, thereby realizing the separation between the permanent magnet rotor 43 and the actuating component 1, which facilitates the inspection and maintenance of both.

[0042] In addition, to ensure sealing performance, a sealing groove 24 can be provided on the side wall of the locking pin 224. An oil O-ring is installed in the sealing groove 24 to prevent hydraulic oil leakage. To ensure the sealing effect, the sealing groove 24 is located below the annular groove where the elastic element 23 is installed. In order to improve the overall strength, the area where the annular groove is set needs to be rounded and surface strengthened (such as shot peening or nitriding) to eliminate stress concentration and improve fatigue life.

[0043] Of course, in another embodiment, the side wall of the locking pin 224 is no longer provided with an annular groove, but a protruding spring seat shoulder is provided on the end face of the locking pin 224 for installing the elastic element 23. In this way, it is not necessary to open too many grooves on the surface of the locking pin 224, thus ensuring the overall strength of the locking pin 224.

[0044] In a preferred embodiment of this application, the actuation component 1 includes a power component 14, a lead screw 11, a sliding block 12, and a protective shell 13 that encloses the lead screw 11 and the sliding block 12. The power component 14 drives the lead screw 11 to rotate, and the sliding block 12 moves along the length of the lead screw 11.

[0045] It should be noted that the structure of the actuating component 1 is not much different from that of the ball screw 11 used in the traditional permanent magnet speed controller 4 to adjust the air gap. The principle is the same. The rotation of the screw 11 drives the sliding block 12 (nut) screwed to the screw 11, thereby realizing the horizontal movement of the sliding block 12, which in turn drives the permanent magnet rotor 43 connected to the sliding block 12 to move. The sliding block 12 is connected to the locking head 22 by a threaded connection. Through the above-mentioned quick-release structure, the connection between the locking head 22 and the connecting head 21 connected to the permanent magnet rotor 43 is realized, thereby realizing the quick disassembly and assembly between the permanent magnet speed controller 4 and the movable support, improving the efficiency of disassembly and assembly, and facilitating the maintenance of each structure.

[0046] Furthermore, the top of the sliding block 12 is connected to the locking head 22, and the connecting head 21 is placed at the bottom of the permanent magnet rotor 43. The locking head 22 slides relative to the outer wall of the connecting head 21. The output end of the drive component has a power component 14, and the lead screw 11 has a mating component 15. The two are staggered. The drive component can adopt a servo motor structure. To avoid the drive component and the lead screw 11 being coaxial, thus affecting the output end of the permanent magnet rotor 43, this application sets the mating component 15 at the lead screw 11 and the power component 14 at the output end of the drive component. The power component 14 and the mating component 15 can adopt a driving gear and driven gear structure (such as a bevel gear structure). Through the gear structure arranged in an upper and lower meshing manner, the output power of the lower power component 14 is transmitted to the upper lead screw 11, realizing the transmission of power. Figure 8 As can be seen, in order to protect the locking head 22 and its internal hydraulic coupling structure, the locking head 22 is also equipped with a protective shell 13 that wraps around and protects the internal structures. This not only provides safety protection but also facilitates its connection with the sliding block 12 below, making it more convenient to use. Of course, other forms can also be used for the transmission connection between the power component 14 and the coupling component 15, such as belt drive, which can also achieve power transmission and avoid mutual interference between the power input of the lead screw 11 and the permanent magnet rotor 43.

[0047] In an alternative embodiment, in order to further reduce the difficulty of installation and maintenance and improve the efficiency of disassembly and maintenance, the scheme is roughly the same as the aforementioned embodiment. A connector 21 structure needs to be set at the bottom of the outer shell of the permanent magnet rotor 43. However, it is not necessary to set an external connecting plate and sliding block 12 structure. Instead, the lead screw 11 and sliding block 12 are directly located at the bottom of the connector 21, and the sliding block 12 is directly connected to the bottom of the connector 21, thereby driving the connector 21 to move horizontally, thereby driving the permanent magnet rotor 43 to move.

[0048] This application also provides a permanent magnet speed regulator 4, applied to a movable support for the permanent magnet speed regulator 4, comprising: an input section 41 for providing power to the permanent magnet speed regulator 4; a conductor rotor 42 connected to the input section 41 for transmitting power; a permanent magnet rotor 43 magnetically coupled to the conductor rotor 42 and connected to the connector 21; an output shaft 44 not in direct contact with the lead screw 11 and outputting power; and a mounting bracket 45 detachably mounted on the surface of the support body 3.

[0049] It can be seen that the overall structure of the permanent magnet speed controller 4 in this application is largely the same as that of other permanent magnet speed controllers 4 in the prior art. The main difference is that the output shaft 44 in this application needs to pass through the hollow lead screw 11. In order to prevent the lead screw 11 from rotating with the output shaft 44 and to prevent the output shaft 44 from rotating with the lead screw 11, a gap should be left between the two to reduce the direct contact between them. Alternatively, a sliding bearing or bushing can be provided on the inner wall of the hollow lead screw 11 to prevent the lead screw 11 and the output shaft 44 from following each other.

[0050] Specifically, in use, the actuating component 1 is connected to the permanent magnet speed regulator 4, and the connector 21 and locking head 22 are initially connected and positioned. The locking head 22 is then fitted onto the surface of the connector 21. Afterward, the hydraulic power unit 51 is started, the internal hydraulic station is activated, and the oil pump draws oil from the oil tank. High-pressure oil enters the annular cylinder 52 through the control valve group, oil pipe, and rotary joint, reaching the tail oil chamber 223 of each locking pin. The oil pressure pushes the locking pin radially inward until it is fully locked. Driving hydraulic oil enters the annular cylinder 52 along the hydraulic oil pipe 53. The hydraulic oil in the annular cylinder 52 travels along the oil passage 521 until it enters the oil chamber 223, pushing the locking pin 224 in the oil chamber 223. This causes the locking pin 224 to move towards the insertion interface 211 until the two are fully assembled, resulting in a tight connection between the connector 21 and the locking head 22. At this point, the control valve group switches to the "neutral" or "pressure holding" state, closing the oil passage 521. The hydraulic oil in the entire locking oil circuit 521 is sealed inside and no longer flows. The huge locking force is maintained by the incompressibility of the liquid. Then, as needed, the drive of the action component 1 is activated. The drive drives the lead screw 11 to rotate. The rotation of the lead screw 11 does not interfere with the rotation of the output shaft 44 of the permanent magnet rotor 43. The lead screw 11 can only rotate. Similarly, the rotation of the sliding block 12 is also restricted. Therefore, the sliding block 12 will be driven to move horizontally due to the rotation of the lead screw 11. Then, as needed, the direction of the drive is adjusted, which in turn drives the locking head 22 connected to the sliding block 12 to move. Since the locking head 22 and the connecting head 21 are assembled with the plug interface 211 through the locking pin 224, the permanent magnet rotor 43 of the permanent magnet speed regulator 4 can be driven to move, realizing the air gap adjustment of the permanent magnet speed regulator 4.

[0051] Furthermore, after a period of use, if the equipment makes abnormal noises, or in a dirty or messy environment (possibly with oil or dust), various tools are needed to disassemble, inspect, repair, adjust, and reassemble a series of interconnected precision parts. However, this application uses the locking pin 224 between the connector 21 and the locking head 22 and the plug interface 211, supplemented by the hydraulic oil supply of the hydraulic drive component 5, to achieve rapid assembly and disassembly. This allows the permanent magnet speed controller 4 to be quickly separated from the action component 1, facilitating separate inspection and maintenance of the two structures. Moreover, after a problem is detected, the action component 1 can be directly replaced without affecting subsequent work. Furthermore, during assembly, since this application uses hydraulic oil to apply force to push the locking pin 224 and the plug interface 211 for locking, compared to the traditional method of assembly using bolts or screws, the assembly of this application is faster and more convenient. In addition, the hydraulic drive connection is more precise, avoiding errors or offsets that occur during manual assembly, and improving the reliability and accuracy of subsequent use and installation.
