Description

Technical Field

[0001] The present invention relates to the technical field of liquid-cooled speed-regulating permanent magnet couplings, and specifically to a lightweight liquid-cooled speed-regulating permanent magnet coupling. Background Art

[0002] A permanent magnet coupling is a non-contact torque transmission device, whose functions include eliminating mechanical friction and wear through magnetic force, providing overload protection to isolate the motor from the load, blocking vibration transmission to reduce noise, and supporting stepless speed regulation and soft start functions, significantly improving system reliability and reducing maintenance costs. Permanent magnet couplings are widely used in high-risk environments and precision manufacturing fields. Compared with traditional mechanical couplings and hydraulic couplings, permanent magnet couplings show significant advantages in terms of transmission efficiency, maintenance requirements, overload protection, and installation convenience.

[0003] When a permanent magnet coupling is in use, the permanent magnet disk on it may be eccentric due to reasons such as bearing wear and installation errors. When the permanent magnet disk is eccentric and misaligned, risks such as mechanical vibration, reduced transmission efficiency, and overheating are likely to occur; and metal impurities generated due to mechanical wear are easily adsorbed by the permanent magnet disk, causing problems such as increased mechanical wear and dynamic imbalance. Summary of the Invention

[0004] The purpose of the present invention is to provide a lightweight liquid-cooled speed-regulating permanent magnet coupling to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A lightweight liquid-cooled speed-regulating permanent magnet coupling, including a support, an outer shell is installed on the support, a transmission component is rotatably installed in the outer shell, an output component is rotatably installed in the outer shell, a compensation component is installed on the output component, a disk component is installed on the compensation component, a detection and cleaning component is installed in the outer shell, the transmission component is connected to the output component, and the disk component is connected to the output component.

[0006] The permanent magnet coupling is externally connected to a control system, and the control system is used to control the entire permanent magnet coupling. The transmission component is connected to an external driver, and the driver is used to drive the transmission shaft to rotate; the output component is connected to an operator, and the output shaft can drive the operator to work.

[0007] Further, the detection and cleaning component includes an electric telescopic rod, the electric telescopic rod is slidably installed in the outer shell, a connecting piece is installed on the output shaft of the electric telescopic rod, a driving motor is installed on the connecting piece, the output shaft of the driving motor penetrates through the connecting piece and a driving gear is installed, a rotating rod is installed on the connecting piece, a rotating measuring rod is rotatably installed on the rotating rod, the rotating measuring rod is in meshing transmission with the driving gear, a detection head is installed at one end of the rotating measuring rod, a cleaning end is installed at the other end of the rotating measuring rod, a negative pressure end head is installed on the cleaning end, the negative pressure end head is externally connected to an air extraction device through a pipeline, and a filter screen is provided at the negative pressure end head.

[0008] The air extraction device evacuates the air in the negative pressure chamber, the dust removal chamber and the cleaning end through a pipeline and a negative pressure end, so that negative pressure suction is generated in the negative pressure chamber and the dust removal chamber.

[0009] The electric telescopic rod can be slidably installed in the housing through an electric slide rail. The electric slide rail can drive the electric telescopic rod to slide, thereby driving the entire detection and cleaning assembly to move. The output shaft of the electric telescopic rod can drive the detection and cleaning assembly to move up and down through a connecting piece; the drive motor is a servo motor, and the output shaft of the drive motor can drive the drive gear to rotate. The drive gear drives the rotating measuring rod engaged with it to deflect. When the arc-shaped scraper of the rotating measuring rod deflects downward to a vertical angle, the detection and cleaning assembly starts the cleaning mode; when the drive gear rotates in the reverse direction, driving the detection head to deflect so that the measuring bead is in pressing contact with the side surface of the rotating disc, the detection and cleaning assembly starts the detection mode.

[0010] Furthermore, a transmission tooth is provided on the rotating measuring rod. The transmission tooth is in meshing transmission with the drive gear. An arc-shaped cantilever is provided at one end of the rotating measuring rod. The detection head is connected to the arc-shaped cantilever. An arc-shaped scraper is provided on the rotating measuring rod. A negative pressure chamber and a dust removal chamber are respectively arranged in the rotating measuring rod. The dust removal chamber is communicated with the negative pressure chamber, and the negative pressure chamber is communicated with the cleaning end.

[0011] After the permanent magnetic coupling works for a long time, the control system adjusts the detection and cleaning assembly to the cleaning mode. The control system drives the disk assembly to move forward by using the compensation assembly until one side of the permanent magnetic block fits with the arc-shaped scraper. Then the control system drives the disk assembly to rotate slowly by using the transmission assembly. The arc-shaped scraper and the permanent magnetic block rotate relatively, and the arc-shaped scraper scrapes off the metal impurities adsorbed on the surface of the permanent magnetic block. The control system turns on the air extraction device to generate negative pressure suction in the negative pressure chamber and the dust removal chamber to suck out the scraped metal impurities and the impurities on the surface of the permanent magnetic block. The sucked impurities converge from the dust removal chamber and the negative pressure chamber into the cleaning end, achieving the purpose of scraping off metal impurities and collecting impurities. After the cleaning is completed, the impurities in the cleaning end are removed.

[0012] Furthermore, the detection head includes a rotating bent rod, a piezoelectric body and a gasket. A measuring bead is installed on the rotating bent rod. The piezoelectric body is installed in the arc-shaped cantilever. The gasket is installed in the arc-shaped cantilever. The gasket is in contact with the piezoelectric body, and a detection spring is installed between the gasket and the rotating bent rod.

[0013] During the working process, the control system regularly controls the detection and cleaning assembly to start the cleaning mode. In the cleaning mode, the detection head presses the side surface of the rotating disc. The measuring bead drives the rotating bent rod to deflect. The distance between the rotating bent rod and the arc-shaped cantilever decreases. The detection spring is in a semi-compressed state. The detection spring presses the piezoelectric body through the gasket. The piezoelectric body generates an electric signal after being pressed. The control system receives the electric signal as the initial value; as the rotating disc rotates, when the centering of the rotating disc is normal and there is no eccentricity, the side surface of the rotating disc rotates stably, the displacement of the measuring bead remains within the error range, and the electric signal fluctuates little;

[0014] When the centering of the rotating disk is poor and eccentricity occurs, the rotating disk drives the measuring disk assembly to rotate eccentrically together. The side of the rotating disk drives the measuring beads to generate large fluctuating displacements. The detection spring in the semi-compressed state rebounds and compresses with the fluctuating displacements of the measuring beads, and the fluctuation of the electrical signal increases accordingly. According to the fluctuation law of the electrical signal, the control system activates the regulator at the corresponding position, and uses the regulator to adjust and compensate the angle of the rotating disk until the electrical signal returns to normal, so as to achieve the compensation adjustment of the eccentric disk assembly.

[0015] Furthermore, the compensation assembly includes a rotating part. A fifth bearing is installed on the rotating part and is connected to the transmission assembly. A compensation disk is connected to the rotating part. A number of regulators are installed on the compensation disk, and a disk assembly is installed on the regulators. The compensation disk is installed on the output assembly.

The push plate is slidably connected to the sleeve. A liquid cavity is provided between the push plate and the sleeve. The infusion end is externally connected to an infusion device through a pipeline.

[0018] The infusion device inputs or extracts hydraulic oil into the liquid cavity through the pipeline and the infusion end.

[0019] Before the work starts, according to the transmission requirements, the control system controls the infusion device to input a preset amount of hydraulic oil into the infusion cavity. After the hydraulic oil enters the liquid cavity, it squeezes the push plate. After being pressed, the push plate drives the sliding sleeve to slide a preset distance on the positioning rod. The sliding sleeve drives the rotating disk to move. The rotating disk drives the sleeve to slide on the output shaft. The sleeve drives the sliding cylinder to adaptively slide on the second ring seat through the fourth bearing. The rotating disk drives the permanent magnet blocks on the permanent magnetic disk to approach the conductor disk. The closer the permanent magnet blocks are to the conductor disk, the stronger the magnetic attraction between the conductor disk and the permanent magnet blocks, the better the transmission efficiency, and the faster the speed of the runner; when deceleration is required, the control system controls the infusion device to extract the hydraulic oil in the liquid cavity, and the push plate drives the sliding sleeve to retract, increasing the distance between the permanent magnet and the conductor disk, reducing the transmission efficiency, and thus reducing the speed of the runner.

[0020] Furthermore, the disk assembly includes a rotating disk. The rotating disk is installed on the sliding sleeve. The rotating disk is located between the fixing rings. A permanent magnetic disk is installed on the rotating disk. A number of permanent magnet blocks are inlaid on the permanent magnetic disk. The permanent magnetic disk is connected to the output assembly.

[0021] Further, the output component includes an output shaft and a second ring seat. A third bearing is installed on the output shaft. The second ring seat is installed on the housing. The third bearing is installed within the second ring seat. A sleeve is movably installed on the output shaft. A fourth bearing is installed on the sleeve. A sliding cylinder is slidably installed on the second ring seat. The fourth bearing is installed within the sliding cylinder. A compensation disc is installed on the output shaft. One end of the output shaft is connected to a rotating member, and the sleeve is connected to a rotating disc.

[0022] Further, the transmission component includes a transmission shaft and a first ring seat. The first ring seat is installed on the housing. A first bearing and a second bearing are respectively installed on the transmission shaft. Both the first bearing and the second bearing are installed within the first ring seat. A connecting flange is installed at one end of the transmission shaft. A connecting disc is installed on the connecting flange. The connecting disc is connected to a liquid cooling device. A conductor disc is installed on one side of the connecting disc close to the permanent magnetic disc. The fifth bearing is connected to the connecting flange.

[0023] The liquid cooling device is used to input circulating coolant into the connecting disc. The coolant is used to take away the heat of the connecting disc and the conductor disc, achieving the purpose of liquid cooling.

[0024] The control system energizes the conductor disc to generate magnetic force. The driver drives the transmission shaft to rotate. The transmission shaft rotates on the first bearing and the second bearing and drives the connecting disc to rotate through the connecting flange. The connecting disc drives the conductor disc to rotate. The conductor disc drives the permanent magnetic disc equipped with permanent magnetic blocks to rotate. The permanent magnetic disc drives the rotating disc to rotate. The rotating disc drives the compensation disc to rotate through the positioning rod. The compensation disc drives the output shaft to rotate. The output shaft drives the actuator to rotate, realizing the transmission function.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By using the slidably arranged electric telescopic rod in cooperation with the drive motor, the position and angle of the detection and cleaning component are adjusted, enabling the detection and cleaning component to freely switch between the cleaning and detection modes according to the operation requirements; the purpose of centering detection and impurity cleaning is achieved through the adjustment of the detection and cleaning component mode.

[0027] 2. By using the synchronous operation of several regulators to adjust the distance between the disk component and the conductor disc, the purpose of fully automatic speed regulation is achieved without manual operation; by using the operation of a single regulator, the angle of the disk component is adjusted to achieve the purpose of dynamic eccentricity adjustment.

[0028] 3. By using the side of the rotating disc to drive the measuring bead to move, the centering degree of the rotating disc is converted into the deflection of the rotating bent rod through the measuring bead. The rotating bent rod and the arc-shaped suspension beam convert the deflection into the compression of the detection spring. The detection spring converts the compression amount into the extrusion of the piezoelectric body, thereby generating an electrical signal that can be recognized by the control system. The control system discriminates the centering degree of the rotating disc according to the fluctuation degree of the electrical signal, realizing the function of centering degree detection;

[0029] 4. When the rotating disk is eccentric, the control system activates the regulator at the corresponding position according to the fluctuation law of the electrical signal, and uses the regulator to adjust and compensate the angle of the rotating disk until the electrical signal returns to normal, thereby achieving the purpose of detecting and compensating the eccentricity of the eccentric disk assembly.

[0052] The detection and cleaning component 6 includes an electric telescopic rod 61, which is slidably installed in the housing 2. A connecting piece 62 is installed on the output shaft 41 of the electric telescopic rod 61. A driving motor 63 is installed on the connecting piece 62.

[0054] The electric telescopic rod 61 can be slidably installed in the housing 2 through an electric slide rail.

[0057] Working principle of the present invention: Before the work starts, according to the transmission requirements, the control system controls the infusion device to input a preset amount of hydraulic oil into the infusion cavity 535. After the hydraulic oil enters the liquid cavity 535, it squeezes the push plate 5322. After being pressed, the push plate 5322 drives the sliding sleeve 532 to slide a preset distance on the positioning rod 531. The sliding sleeve 532 drives the rotating disk 71 to move. The rotating disk 71 drives the bushing 45 to slide on the output shaft 41. The bushing 45 drives the sliding cylinder 44 to adaptively slide on the second ring seat 43 through the fourth bearing 46. The rotating disk 71 drives the permanent magnet block 73 on the permanent magnet disk 72 to approach the conductor disk 35. The closer the permanent magnet block 73 is to the conductor disk 35, the stronger the magnetic attraction between the conductor disk 35 and the permanent magnet block 73, the better the transmission efficiency, and the faster the speed of the operator. When deceleration is required, the control system controls the infusion device to pump out the hydraulic oil in the liquid cavity 535. The push plate 5322 drives the sliding sleeve 532 to retract, increasing the distance between the permanent magnet and the conductor disk 35, reducing the transmission efficiency, and thus reducing the speed of the operator.

[0058] The control system energizes the conductor disk 35 to generate magnetic force. The driver drives the transmission shaft 31 to rotate. The transmission shaft 31 rotates on the first bearing 36 and the second bearing 37, and drives the connecting disk 34 to rotate through the connecting flange 33. The connecting disk 34 drives the conductor disk 35 to rotate. The conductor disk 35 drives the permanent magnet disk 72 equipped with the permanent magnet block 73 to rotate. The permanent magnet disk 72 drives the rotating disk 71 to rotate. The rotating disk 71 drives the compensation disk 54 to rotate through the positioning rod 531. The compensation disk 54 drives the output shaft 41 to rotate. The output shaft 41 drives the operator to rotate, realizing the transmission function.

[0059] During the working process, the control system regularly controls the detection and cleaning component 6 to turn on the cleaning mode. In the cleaning mode, the detection head 66 squeezes the side of the rotating disk 71. The measuring bead 665 drives the rotating bent rod 664 to deflect. The distance between the rotating bent rod 664 and the arc-shaped suspension beam 655 decreases. The detection spring 661 is in a semi-compressed state. The detection spring 661 squeezes the piezoelectric body 662 through the gasket 663. After being pressed, the piezoelectric body 662 generates an electric signal. After receiving the electric signal, the control system takes it as the initial value. As the rotating disk 71 rotates, when the centering of the rotating disk 71 is normal and there is no eccentricity, the side of the rotating disk 71 rotates stably, the displacement of the measuring bead 665 remains within the error range, and the electric signal fluctuates little.

[0060] When the centering of the rotating disk 71 is poor and eccentricity occurs, the rotating disk 71 drives the measuring disk assembly to rotate eccentrically together. The side of the rotating disk 71 drives the measuring bead 665 to generate a large fluctuating displacement. The detection spring 661 in the semi-compressed state rebounds and compresses with the fluctuating displacement of the measuring bead 665, and the fluctuation of the electric signal increases accordingly. According to the fluctuation law of the electric signal, the control system turns on the regulator 53 at the corresponding position, and uses the regulator 53 to adjust and compensate the angle of the rotating disk 71 until the electric signal returns to normal, so as to achieve the compensation adjustment of the eccentric disk assembly 7.

[0061] After the permanent magnet coupling works for a long time, the control system adjusts the cleaning component 6 to the cleaning mode. The control system drives the disk component 7 to move forward by using the compensation component 5 until one side of the permanent magnet block 73 is in contact with the arc-shaped scraper 654. Then, the control system drives the disk component 7 to rotate slowly by using the transmission component 3. The arc-shaped scraper 654 and the permanent magnet block 73 rotate relative to each other, and the arc-shaped scraper 654 scrapes off the metal impurities adsorbed on the surface of the permanent magnet block 73. The control system turns on the air extraction device to generate negative pressure suction in the negative pressure chamber 652 and the dust removal chamber 653 to suck out the scraped metal impurities and the impurities on the surface of the permanent magnet block 73. The sucked impurities converge from the dust removal chamber 653 and the negative pressure chamber 652 to the cleaning end 67, achieving the purpose of scraping off the metal impurities and collecting the impurities. After the cleaning is completed, the impurities in the cleaning end 67 are removed.
