Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of clutches, and particularly to a fast-switching, high-torque electromagnetic clutch. Background Technology

[0002] An electromagnetic clutch is an electromechanical integrated product that performs mechanical transmission conversion. It features a simple structure, can be connected and disconnected, and is easy to connect, making it widely used in various industrial fields.

[0003] Electromagnetic clutches are widely used in the field of industrial mechatronics because they are convenient to transmit torque, can be connected and disconnected. However, the overall torque transmitted by electromagnetic clutches is relatively small and the switching time is relatively long, which affects their application in situations where time and high torque transmission are required. Summary of the Invention

[0004] Purpose of the invention: The present invention provides a fast-switching high-torque electromagnetic clutch to solve the problems of conventional electromagnetic clutches having low torque transmission and slow switching from connection to disconnection and from disconnection to connection.

[0005] Technical solution: A fast-switching, high-torque electromagnetic clutch is provided, including an electromagnetic mechanism, and further comprising: Drive shaft, connecting plate, conversion plate, drive shaft, armature; The drive shaft and connecting plate are connected by spline internal gears, the connecting plate and conversion plate are connected by helical gears, and the conversion plate and drive shaft are connected by spline internal gears. The connecting plate and conversion plate connect the drive shaft and drive shaft to transmit torque when no power is applied. The drive shaft, drive shaft and external structure are connected by screws or splines. A flange is set on the drive shaft near the middle right of the connecting plate. The electromagnetic mechanism is installed on the drive shaft to the left of the flange. The channel between the electromagnetic mechanism and the flange serves as the movement channel for the armature. The armature and connecting plate are connected by meshing.

[0006] Furthermore, the electromagnetic clutch also includes: a pull rod; One end of the pull rod is fixed to the armature with fasteners, and the other end engages with the outer circle of the connecting plate. The pull rod is used to separate the connecting plate from the conversion plate when the armature is attracted by the energized coil assembly, thereby separating the drive shaft from the transmission shaft.

[0007] Furthermore, the electromagnetic clutch also includes: a large housing and a small housing; The housing consists of a large housing and a small housing. A pair of through holes are provided at the central axis of the housing. The drive shaft is inserted through one through hole and the transmission shaft is inserted through the other through hole. The large housing is also used to guide the movement of the armature. The connection between the large and small housings is located between the flange and the connecting plate.

[0008] Furthermore, the electromagnetic clutch also includes a spring; The spring is assembled in the large housing to generate a reaction force to spring the armature 8 back to the initial working position when the coil assembly is de-energized.

[0009] Furthermore, the electromagnetic clutch also includes a disc spring; The disc spring is mounted on the connecting plate. There is a gap between the flange and the connecting plate. The side of the flange closest to the connecting plate has a disc spring groove.

[0010] Furthermore, the drive shaft supports the large housing via a second bearing; the transmission shaft supports the small housing via a first bearing.

[0011] Furthermore, the iron core is fixed to the large housing by screws, spring washers, and washers.

[0012] Furthermore, the small housing and the large housing are connected together by screws, spring washers, and gaskets.

[0013] Beneficial effects: This invention enables the clutch to switch quickly by designing the electromagnet part, and the structural design allows the clutch to transmit a large torque, thereby solving the problems of low overall torque transmission and long switching time of electromagnetic clutches. It can achieve the effect of rapid switching and transmission of large torque, and has broad application prospects. Attached Figure Description

[0023] This invention provides a fast-switching, high-torque electromagnetic clutch. On one hand, it addresses the problem of long switching times in traditional electromagnetic clutches during engagement and disengagement. Based on the electromagnetic and structural design of the electromagnet and transmission components, it achieves rapid clutch switching through the rapid working principle of the electromagnet, thus solving the problem of long switching times in traditional clutches. On the other hand, the connecting plate and conversion plate of this fast-switching, high-torque electromagnetic clutch use tooth meshing to transmit high torque from the drive shaft to the transmission shaft, thereby solving the problem of transmission electromagnetic clutches being unable to transmit high torque. This invention's fast-switching, high-torque electromagnetic clutch features fast switching time and high load-carrying capacity. The fast-switching, high-torque electromagnetic clutch provided by this invention has been well applied in fields such as industrial equipment, aerospace, and weapon assembly where electromagnetic clutches are required. Furthermore, the coil and number of meshing teeth can be flexibly adjusted according to actual needs, showing promising application prospects.

[0024] This invention provides a fast-switching high-torque electromagnetic clutch, such as... Figure 1 As shown, it includes: drive shaft 1, connecting plate 11, conversion plate 12, and transmission shaft 15; The drive shaft 1 and connecting plate 11 are connected by splined internal teeth. The connecting plate 11 and conversion plate 12 are engaged by helical teeth. The conversion plate 12 and drive shaft 15 are connected by splined internal teeth. The connecting plate 11 and conversion plate 12 connect the drive shaft 1 and drive shaft 15 to transmit torque without power. The drive shaft 1 and drive shaft 15 can be connected to external structures by screws or splines.

[0025] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a large housing 6; The housing 6 serves as a structural support for the iron core 5, the second bearing 18, and the spring 7, and also serves as a motion guide for the armature 8.

[0026] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including an iron core 5 and an armature 8; When the coil assembly 17 is energized, the iron core 5 and armature 8 generate an electromagnetic field that converts electrical energy into mechanical energy, producing a certain attraction force. This force drives the pull rod 9 to move, thus separating the connecting plate 11 from the conversion plate 12. The iron core 5 is fixed to the large housing 6 by screws 2, spring washers 3, and washers 4.

[0027] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a spring 7; The spring 7 is assembled in the large housing 6 and is used to generate a reaction force to spring the armature 8 back to the initial working position when the coil assembly 17 is de-energized.

[0028] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a pull rod 9; The pull rod 9 is fixed to the armature 8 by fasteners and is used to separate the connecting plate 11 from the conversion plate 12 when the armature 8 is attracted by the energized coil assembly 17, thereby separating the drive shaft 1 from the transmission shaft 15.

[0029] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a small housing 10; The small housing 10 is used for product structural support and for supporting the elastic retaining ring 14 and the first bearing 16. The small housing 10 and the large housing 6 are connected together by screws 2, spring washers 3 and washers 4.

[0030] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a disc spring 13; The disc spring 13 is assembled between the drive shaft 1 and the connecting plate 11. When the power is on, it is compressed when the connecting plate 11 is attracted. When the power is off, the spring force will cause the connecting plate 11 to spring back to the initial position, so that the connecting plate 11 and the conversion plate 12 can mesh together to achieve the connection and transmission function.

[0031] Optionally, the fast-switching high-torque electromagnetic clutch described above is characterized by further including a coil assembly 17; The coil assembly 17 is used to generate an electromagnetic field when energized. The electromagnetic field generated by the coil assembly 17 magnetizes the armature 8 and the iron core 5, converting electromagnetic force into mechanical force to realize the movement of the armature 8. The coil assembly 17 can adjust the coil parameters according to the user's requirements for working time to achieve a rapid separation and switching effect.

[0032] See Figure 1 The fast-switching high-torque electromagnetic clutch shown in this embodiment specifically includes: a drive shaft 1; a screw 2; a spring washer 3; a washer 4; an iron core 5; a large housing 6; a spring 7; an armature 8; a pull rod 9; a small housing 10; a connecting plate 11; an adapter plate 12; a disc spring 13; an elastic retaining ring 14; a drive shaft 15; a first bearing 16; a coil assembly 17; and a second bearing 18.

[0033] The drive shaft 1 is connected to the connecting plate 11 via spline internal teeth. The connecting plate 11 is connected to the conversion plate 12 via helical teeth. The conversion plate 12 is connected to the drive shaft 15 via spline internal teeth. The connecting plate 11 and the conversion plate 12 connect the drive shaft 1 and the drive shaft 15 to transmit torque without power. The drive shaft 1 and the drive shaft 15 can be connected to external structures via screws or splines.

[0034] In this implementation example, the housing 6 serves as a structural support for the iron core 5, the second bearing 18, and the spring 7, and also serves as a motion guide for the armature 8.

[0035] In this embodiment, after the coil assembly 17 is energized, the iron core 5 and armature 8 generate an electromagnetic field that converts electrical energy into mechanical energy, producing a certain attraction force. This force drives the pull rod 9 to move, thus separating the connecting plate 11 from the conversion plate 12. The iron core 5 is fixed to the large housing 6 by screws 2, spring washers 3, and washers 4.

[0036] In this embodiment, spring 7 is assembled in the large housing 6 to generate a reaction force to spring armature 8 back to its initial working position when coil assembly 17 is de-energized.

[0037] In this embodiment, the pull rod 9 is fixed to the armature 8 by fasteners, and is used to separate the connecting plate 11 from the conversion plate 12 when the armature 8 is attracted by the energized coil assembly 17, thereby realizing the separation of the drive shaft 1 from the transmission shaft 15.

[0038] In this embodiment, the pull rod 9 is fixed to the armature 8 by fasteners, and is used to separate the connecting plate 11 from the conversion plate 12 when the armature 8 is attracted by the energized coil assembly 17, thereby realizing the separation of the drive shaft 1 from the transmission shaft 15.

[0039] In this embodiment, the disc spring 13 is assembled between the drive shaft 1 and the connecting plate 11. When the power is on, it is compressed when the connecting plate 11 is attracted. When the power is off, the connecting plate 11 is springed back to the initial position by the spring reaction force, so that the connecting plate 11 and the conversion plate 12 are engaged together to realize the connection and transmission function.

[0040] In this embodiment, the coil assembly 17 is used to generate an electromagnetic field when energized. The electromagnetic field generated by the coil assembly 17 magnetizes the armature 8 and the iron core 5, converting electromagnetic force into mechanical force to realize the movement of the armature 8. The coil assembly 17 adjusts the coil parameters according to the user's requirements for working time to achieve a rapid separation and switching effect.

[0041] For example, the fast-switching high-torque electromagnetic clutch provided by the present invention can be applied in situations requiring fast switching time or in places where high torque is transmitted, and can also be applied in electromagnetic clutches in normal working conditions.

[0042] This embodiment provides a specific structure for a fast-switching, high-torque electromagnetic clutch. Through the design of the overall structure, coil structure, magnetic circuit structure, and conversion structure, the electromagnetic and structural design of the electromagnet part of the electromagnetic clutch, as well as the structural design of the transmission part, achieves rapid clutch switching by leveraging the rapid working principle of the electromagnet. This solves the problem of long switching times in traditional clutches and achieves the goal of rapid switching. Furthermore, the connecting plate and conversion plate of the fast-switching, high-torque electromagnetic clutch provided in this embodiment of the invention use a gear meshing method to achieve the transmission of high torque from the drive shaft to the transmission shaft, thereby solving the problem that transmission electromagnetic clutches cannot transmit high torque. Specifically, it is applicable to various fast-switching electromagnetic clutches and electromagnetic clutches with large transmission torque, expanding the applicability of fast-switching, high-torque electromagnetic clutches.
