Technical Field

[0002] Speed-regulating permanent magnet couplers are purely mechanical devices that use magnetic fields as a medium for transmission. By adjusting the air gap between the copper conductor and the permanent magnet, the torque transmitted from the motor to the load can be precisely controlled, thereby adjusting the load speed and achieving energy saving. They are suitable for various harsh working conditions and require no special maintenance.

[0037] Combination Figures 1 to 4 As shown in the specific embodiment of this application, a speed-regulating permanent magnet coupler is provided.

[0038] Specifically, the speed-regulating permanent magnet coupler includes: a housing 200, an input component 100, an output component 600, an actuation component 400, and a transmission component. The input component 100 is connected to the housing 200 and has an input shaft 103 rotatably connected to the housing 200. A copper conductor 113 is located at the end of the input shaft 103. The output component 600 is connected to the housing 200 and has an output shaft 604 rotatably connected to the housing 200. A permanent magnet is located at one end of the output shaft 604 near the copper conductor 113, forming a magnetic field air gap between the permanent magnet and the copper conductor 113. The actuation component 400 is connected to the output component 600 via the transmission component and is used to drive the permanent magnet to move axially along the output shaft 604. The input shaft 103 has a mounting part at its end, and the input shaft 103 is rotatably connected to the output shaft 604 through the mounting part. The mounting part is spaced apart from the permanent magnet along the axial direction of the output shaft 604.

[0039] In the embodiments of this application, the input shaft 103 of the input component 100 is rotatably connected to the output shaft 604 of the output component 600 through the mounting part, that is, the input component 100 and the output component 600 are connected to form an integral structure. One end of the integral structure is connected to the housing 200 through the input component 100, and the other end of the integral structure is connected to the housing 200 through the output component 600, forming an integral structure with double support, thereby improving the stability of the whole machine and reducing the vibration of the whole machine, that is, reducing the vibration of the input component 100 and the output component 600.

[0040] It should be noted that the housing 200 has a receiving cavity, and the housing 200 has a first opening and a second opening communicating with the receiving cavity. An end cap 300 is installed at the first opening of the housing 200, and the end cap 300 has a third opening. The input component 100 is connected to the housing 200 through the end cap 300, and the input component 100 extends into the receiving cavity of the housing 200 sequentially through the third opening and the first opening. The output component 600 is connected to the housing 200, and the output component 600 extends into the receiving cavity of the housing 200 through the second opening.

[0041] In one exemplary embodiment of this application, the mounting portion is a mounting groove formed at the end of the input shaft 103. A support bearing 700 is provided in the mounting groove, the outer ring of the support bearing 700 is connected to the mounting groove, and the inner ring of the support bearing 700 is connected to the output shaft 604. This structure integrally molds the mounting portion onto the input shaft 103, reducing the number of parts in the machine and improving the overall stability of the machine to some extent.

[0042] Specifically, such as Figure 1 As shown, the support bearing 700 is disposed in the mounting groove. The first end of the outer ring of the support bearing 700 abuts against the bottom of the mounting groove, and the second end of the outer ring of the support bearing 700 abuts against the spring retaining ring installed in the mounting groove, thereby realizing the installation of the support bearing 700. The inner ring of the support bearing 700 is interference-fitted with the output shaft 604, thereby realizing the connection between the output shaft 604 and the support bearing 700.

[0043] In one exemplary embodiment of this application, the input assembly 100 further includes: an input bearing housing 108, a first input bearing 101, and a second input bearing 109. The input bearing housing 108 is connected to the housing 200, and has a first mounting position and a second mounting position, which are spaced apart along the axial direction of the input shaft 103 bearing housing. The first input bearing 101 is located at the first mounting position, and its inner ring is connected to the input shaft 103. The second input bearing 109 is located at the second mounting position, and its inner ring is connected to the input shaft 103. In this structure, the first input bearing 101 and the second input bearing 109 form a double-support structure, providing synchronous support for the input shaft 103. Compared to a cantilever structure, this improves the stability of the input shaft 103 and reduces the vibration of the input assembly 100.

[0044] Specifically, such as Figure 2 As shown, the first input bearing 101 is a paired angular contact ball bearing, and the second input bearing 109 is a cylindrical roller bearing. The input bearing housing 108 is connected to the housing 200 via an end cap 300. The input bearing housing 108 has an axially penetrating first cavity, which has a stepped structure with a first stepped surface and a second stepped surface. The first input bearing 101 is installed in the first cavity. The first end of the outer ring of the first input bearing 101 abuts against the first stepped surface, and the second end of the outer ring is pressed against a first pressure cap 106. The first pressure cap 106 is connected to the end of the input bearing housing 108, thus positioning the outer ring of the first input bearing 101. The second input bearing 109 is installed in the first cavity. The first end of the outer ring of the second input bearing 109 abuts against the second stepped surface, and the second end of the outer ring abuts against a second input sealing cap 110. The second input sealing cap 110 is connected to the end of the input bearing housing 108, thus positioning the outer ring of the second input bearing 109. The second end of the inner ring of the first input bearing 101 abuts against the first locking nut 102, which is threadedly connected to the input shaft 103. The second end of the inner ring of the second input bearing 109 abuts against the shoulder of the input shaft 103. An input spacer 115 is fitted on the input shaft 103. One end of the input spacer 115 abuts against the first end of the inner ring of the first input bearing 101, and the other end of the input spacer 115 abuts against the first end of the inner ring of the second input bearing 109, thereby achieving the positioning of the inner rings of the first input bearing 101 and the second input bearing 109.

[0045] like Figure 2As shown, the input assembly 100 further includes: a first input sealing cover 107, a first input sealing ring 104, and an input sealing ring 105. The first input sealing cover 107 is connected to the end of the input bearing housing 108 away from the copper conductor 113. The first input sealing cover 107 is rotatably connected to the input shaft 103 through the first input sealing ring 104. The outer ring of the input sealing ring 105 is sealed to the first input sealing cover 107, and the inner ring of the input sealing ring 105 is rotatably connected to the input shaft 103.

[0046] The first input sealing cover 107 is sealed to the input shaft 103 through the first input sealing ring 104 and the input sealing ring 105, which plays a sealing role and prevents external impurities from entering the whole machine through the first opening of the housing 200.

[0047] In one exemplary embodiment of this application, the input component 100 further includes: a conductor mounting plate 112, an oil catch ring 111, and an oil inlet pipe 116. The conductor mounting plate 112 is connected to the end of the input shaft 103, and a copper conductor 113 is connected to the end of the conductor mounting plate 112 near the permanent magnet. A first oil cooling chamber is formed between the conductor mounting plate 112 and the copper conductor 113, and the first oil cooling chamber has an oil outlet communicating with the outside. The oil catch ring 111 is connected to the end of the conductor mounting plate 112 away from the permanent magnet, and a second oil cooling chamber is formed between the oil catch ring 111 and the input shaft 103. The second oil cooling chamber communicates with the oil inlet of the first oil cooling chamber, and the oil inlet pipe 116 is connected to the first oil cooling chamber.

[0048] Cooling oil flows into the second oil-cooling chamber through the oil inlet pipe 116. Cooling oil in the second oil-cooling chamber then flows into the first oil-cooling chamber through the oil inlet. After heat exchange with the copper conductor 113, the cooling oil flows out through the oil outlet, thus carrying away the heat generated during the operation of the speed-regulating permanent magnet coupler and improving its load capacity. Figure 2 The direction of the middle arrow indicates the flow of cooling oil.

[0049] Furthermore, the input assembly 100 also includes: a second input sealing cover 110, which is connected to one end of the input bearing housing 108 near the copper conductor 113. The second input sealing cover 110 is rotatably connected to the input shaft 103 via a second input sealing ring 114. An oil catch ring 111 is sleeved on the outside of the second input sealing cover 110, and the oil catch ring 111 is rotatably engaged with the second input sealing cover 110. The second input sealing cover 110 is provided with an oil inlet channel, one end of which is connected to an oil inlet port, and the other end of which is connected to an oil inlet pipe 116.

[0050] Specifically, such as Figure 2As shown, the oil catch ring 111 and the second input sealing cover 110 are rotatably fitted together, that is, the oil catch ring 111, the second input sealing cover 110, and the input shaft 103 together form the second oil cooling chamber. The second input sealing cover 110 is rotatably connected to the input shaft 103 through the second input sealing ring 114 to perform a sealing function and prevent cooling oil from flowing into the input bearing housing 108.

[0051] In one exemplary embodiment of this application, the output assembly 600 further includes: an output bearing housing 609, a first output bearing 613, and a second output bearing 621. The output bearing housing 609 is connected to the housing 200, and has a third mounting position and a fourth mounting position, which are spaced apart along the axial direction of the output shaft 604 bearing housing. The first output bearing 613 is located at the third mounting position, and its inner ring is connected to the output shaft 604. The second output bearing 621 is located at the fourth mounting position, and its inner ring is connected to the output shaft 604. In this structure, the first output bearing 613 and the second output bearing 621 form a double-support structure, providing synchronous support for the output shaft 604. Compared to a cantilever structure, this improves the stability of the output shaft 604 and reduces the vibration of the output assembly 600.

[0052] Specifically, such as Figure 3 As shown, the output bearing housing 609 has an axially penetrating second cavity. The second cavity has a stepped structure, and a third, fourth, and fifth stepped surface are provided within the second cavity, arranged sequentially from right to left. An outer output spacer 614 and an inner output spacer 615 are fitted onto the output shaft 604. The outer output spacer 614 is fitted outside the inner output spacer 615, and both the outer and inner output spacers 614 and 615 are located between the first output bearing 613 and the second output bearing 621. The first end of the outer ring of the first output bearing 613 abuts against the third stepped surface, and the second end of the outer ring of the first output bearing 613 abuts against the outer output spacer 614, thus positioning the outer ring of the first output bearing 613. The first end of the inner ring of the first output bearing 613 abuts against the shoulder of the output shaft 604, and the second end of the inner ring of the first output bearing 613 abuts against the inner output spacer 615, thus positioning the inner ring of the first output bearing 613. The first end of the outer ring of the second output bearing 621 abuts against the outer output spacer 614, and the second end of the outer ring of the second output bearing 621 abuts against the fourth pressure cap 616. The fourth pressure cap 616 is connected to the end of the output bearing housing 609, thereby positioning the outer ring of the second output bearing 621. The first end of the inner ring of the second output bearing 621 abuts against the inner output spacer 615, and the second end of the inner ring of the second output bearing 621 abuts against the second locking nut 620. The second locking nut 620 is connected to the output shaft 604, thereby positioning the inner ring of the second output bearing 621.

[0053] In one exemplary embodiment of this application, the transmission assembly includes: a spline seat 603, a trapezoidal threaded sleeve 611, a worm gear 610, a second pressure cap 608, and a worm assembly 500.

The trapezoidal threaded sleeve 611 is sleeved on the outside of the spline seat 603, and the outer wall of the trapezoidal threaded sleeve 611 is slidably connected to the output bearing seat 609 via a guide key 607. The inner wall of the trapezoidal threaded sleeve 611 is rotatably connected to the spline seat 603 via a first bearing 605. The worm gear 610 is sleeved on the outside of the trapezoidal threaded sleeve 611, and the worm gear 610 is threadedly connected to the trapezoidal threaded sleeve 611. The second pressure cap 608 is connected to the end of the output bearing seat 609 near the permanent magnet, and a limiting space is formed between the second pressure cap 608 and a protrusion on the inner wall of the output bearing seat 609, within which the worm gear 610 is located. The worm assembly 500 is connected to the output bearing housing 609, the worm 506 of the worm assembly 500 is meshed with the worm wheel 610, and the worm 506 is connected to the actuation assembly 400, which is used to drive the worm 506 to rotate.

[0054] Specifically, such as Figure 3 As shown, a magnet mounting plate 601 is connected to the side of the spline holder 603 near the copper conductor 113. The magnet mounting plate 601 is connected to the magnet cover plate 602, and a permanent magnet is installed between the magnet mounting plate 601 and the magnet cover plate 602. The spline holder 603 is slidably connected to the output shaft 604 via a spline. A trapezoidal threaded sleeve 611 is fitted onto the outside of the spline holder 603, and the trapezoidal threaded sleeve 611 is rotatably connected to the spline holder 603 via a first bearing 605. There are two first bearings 605. The speed-regulating outer spacer 606 and the speed-regulating inner spacer 624 are both fitted onto the output shaft 604. The speed-regulating outer spacer 606 and the speed-regulating inner spacer 624 are located between the two first bearings 605, with the speed-regulating outer spacer 606 fitted onto the outside of the speed-regulating inner spacer 624.

[0055] One end of the outer ring of the first bearing 605 abuts against the inner flange of the trapezoidal threaded sleeve 611, the second end of the outer ring of the first bearing 605 abuts against the speed regulating outer spacer 606, the first end of the inner ring of the first bearing 605 abuts against the shoulder of the spline seat 603, and the second end of the inner ring of the first bearing 605 abuts against the speed regulating inner spacer 624, thereby achieving the positioning of the first bearing 605.

[0056] Another first bearing 605 has its outer ring's first end abutting against the third pressure cap 612, which is connected to the end of the trapezoidal threaded sleeve 611. The second end of the outer ring of the first bearing 605 abuts against the speed-regulating outer spacer 606. The first end of the inner ring of the first bearing 605 abuts against the third locking nut 622, which is connected to the spline seat 603. The second end of the inner ring of the first bearing 605 abuts against the speed-regulating inner spacer 624, thus achieving the positioning of the first bearing 605.

[0057] A second pressure cap 608 is connected to the end of the output bearing housing 609 near the permanent magnet. The second pressure cap 608 extends into the output bearing housing 609, and a groove is provided on the inner wall of the second pressure cap 608. A guide key 607 is connected to the outer wall of the trapezoidal threaded sleeve 611, and the guide key 607 extends into the groove to achieve a sliding connection between the trapezoidal threaded sleeve 611 and the second pressure cap 608, that is, a sliding connection between the trapezoidal threaded sleeve 611 and the output bearing housing 609. A worm gear 610 is fitted on the outside of the trapezoidal threaded sleeve 611, and the trapezoidal threaded sleeve 611 is threadedly connected to the worm gear 610. The second pressure cap 608 and the protrusion on the inner wall of the output bearing housing 609 form a limiting space, and the worm gear 610 is confined within this limiting space.

[0058] The worm gear assembly 500 is connected to the output bearing housing 609. The worm 506 of the worm gear assembly 500 is meshed with the worm wheel 610. The actuator 400 drives the worm 506 to rotate, which in turn drives the worm wheel 610 to rotate. The worm wheel 610 is confined within a confined space. During the rotation of the worm wheel 610, the trapezoidal threaded sleeve 611 moves axially relative to the worm wheel 610. The trapezoidal threaded sleeve 611 drives the spline seat 603 to move axially, thereby realizing the circumferential movement of the permanent magnet and changing the air gap of the magnet. The actuator 400 can be a motor, electric cylinder, etc.

[0059] Furthermore, the spline seat 603 is connected to the output shaft 604 via a guide belt 623 to ensure the fitting accuracy between it and the output shaft 604, preventing vibration during high-speed rotation due to excessive clearance. The guide belt 623 is made of phenolic resin or a similar wear-resistant material to reduce frictional resistance.

[0060] Specifically, the worm gear assembly 500 further includes: a transition shaft 501, a coupling 502, a second bearing 505, a worm gear seat 507, and a third bearing 508. The worm gear seat 507 is fixed to the output bearing seat 609 by bolts. The worm 506 is mounted on the worm gear seat 507. One end of the worm 506 is rotatably connected to the worm gear seat 507 via the second bearing 505, and the other end of the worm 506 is rotatably connected to the worm gear seat 507 via the third bearing 508. The first end of the outer ring of the second bearing 505 abuts against the worm gear seat 507, the second end of the outer ring of the second bearing 505 abuts against the fifth pressure cap 503, the first end of the inner ring of the second bearing 505 abuts against the fourth locking nut 504, and the first end of the inner ring of the second bearing 505 abuts against the shoulder of the worm 506.

The transition shaft 501 is connected to the worm gear 506 via the coupling 502, and the actuator 400 is connected to the transition shaft 501.

[0061] In one exemplary embodiment of this application, the output assembly 600 further includes an output sealing cover 617, which is connected to the end of the output bearing housing 609 away from the permanent magnet, and the output sealing cover 617 is rotatably connected to the output shaft 604 via an output sealing ring 619.

[0062] The output sealing cover 617 is rotatably connected to the output shaft 604 via the output sealing ring 619 to provide a sealing function and prevent external impurities from entering the output bearing seat 609 through the second opening of the housing 200.

[0063] Furthermore, the output assembly 600 also includes an output sealing ring 618, the outer ring of which is sealed to the output sealing cover 617, and the inner ring of which is rotatably connected to the output shaft 604.

[0064] The output sealing ring 618 further enhances the sealing effect.

[0065] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0066] 1. The input shaft 103 of the input component 100 is rotatably connected to the output shaft 604 of the output component 600 through the mounting part. That is, the input component 100 and the output component 600 are connected to form an integral structure. One end of the integral structure is connected to the housing 200 through the input component 100, and the other end of the integral structure is connected to the housing 200 through the output component 600, forming an integral structure with double support, thereby improving the stability of the whole machine and reducing the vibration of the whole machine, that is, reducing the vibration of the input component 100 and the output component 600.

[0067] 2. The first input bearing 101 and the second input bearing 109 form a double support structure to provide synchronous support for the input shaft 103. Compared with the cantilever structure, this improves the stability of the input shaft 103 and reduces the vibration of the input assembly 100.

[0068] 3. Cooling oil flows into the second oil cooling chamber through the oil inlet pipe 116. The cooling oil in the second oil cooling chamber flows into the first oil cooling chamber through the oil inlet. After exchanging heat with the copper conductor 113, the cooling oil flows out through the oil outlet, thereby carrying away the heat generated during the operation of the speed-regulating permanent magnet coupler and thus improving the load capacity of the speed-regulating permanent magnet coupler.

[0069] 4. The first output bearing 613 and the second output bearing 621 form a double support structure to provide synchronous support for the output shaft 604. Compared with the cantilever structure, this improves the stability of the output shaft 604 and reduces the vibration of the output assembly 600.
