[0055] This application discloses an integrated electromagnetic clutch.

[0056] Please see Figures 1 to 3 ,as well as Figure 5 One embodiment of an integrated electromagnetic clutch provided in this application includes:

[0057] The main body shell 1, coil assembly 2, push ring assembly 3, and transmission component 6.

[0058] The main body shell 1 includes a main shell 11 and a main end cover 12. The main shell 11 is an annular shell structure, while the main end cover 12 is an annular cover plate structure. The specific structure can be designed and modified according to actual needs without limitation.

[0059] The main end cap 12 is fixed to one end of the axial opening of the main housing 11, where the axial direction is the central axial direction of the main housing 11.

[0060] The coil assembly 2 is integrally connected to the housing ring 4. The housing ring 4 has a ring body and a connecting part 41 integrally formed on the edge of the ring body. The connecting part 41 is integrally connected to the coil assembly 2.

[0061] A push ring mounting cavity is formed between the housing ring 4 and the coil assembly 2. The push ring assembly 3 is installed in the push ring mounting cavity. When the coil assembly 2 is energized, it can drive the push ring assembly 3 to move under the action of the magnetic field.

[0062] The coil assembly 2 is installed between the main housing 11 and the main end cover 12, and is fixed by the main housing 11 and the main end cover 12.

[0063] The transmission assembly 6 includes a toothed disc 62, a toothed disc 61, and a reset elastic element 63.

[0064] The toothed disc 61 is rotatably mounted on the main housing 11 via the first bearing 51 and is fixedly fitted onto the toothed disc shaft 8; the toothed disc 62 is disposed on one side of the toothed disc 61 and is movably fitted onto the motor shaft 7, and can move closer to or away from the toothed disc 61 along the axial direction of the motor shaft 7; the toothed disc 61 has a toothed portion 611 at one end facing the toothed disc 62, and the toothed disc 62 has a toothed portion 621 that meshes with the toothed portion 611 at one end facing the toothed disc 61.

[0065] The motor shaft 7 and the toothed disc shaft 8 are coaxially fitted. The end section of the toothed disc shaft 8 can extend into the motor shaft 7. When the toothed disc 61 and the toothed disc 62 are separated, they can rotate relative to each other. When the toothed disc 61 and the toothed disc 62 are engaged, they can rotate synchronously to complete the power transmission.

[0066] The push ring assembly 3 contacts the toothed disc 62 and can drive the toothed disc 62 to move when the coil assembly 2 is energized, so that the toothed disc 62 engages or disengages with the toothed disc 61; the reset elastic element 63 contacts the toothed disc 62 and is used to provide a reset force for the reset movement of the toothed disc 62. When the push ring assembly 3 drives the toothed disc 62 to disengage from the toothed disc 61, the reset elastic element 63 is used to drive the toothed disc 62 to engage with the toothed disc 61 when the coil assembly 2 is not energized; when the push ring assembly 3 drives the toothed disc 62 to engage with the toothed disc 61, the reset elastic element 63 is used to drive the toothed disc 62 to disengage from the toothed disc 61 when the coil assembly 2 is not energized.

[0067] The integrated electromagnetic clutch designed in this application has the following beneficial effects:

[0068] The push ring mounting cavity required for mounting the push ring assembly 3 is formed by the housing ring 4 integrally connected to the coil assembly 2, thereby integrating the push ring assembly 3 with the coil assembly 2. The integrated coil push ring portion, along with the toothed disc 61, the toothed clutch disc 62, and the reset elastic element 63, is then mounted in the main housing 1 to form an integrated electromagnetic core structure. This integrated electromagnetic core structure is then connected to the motor shaft 7 and the toothed disc shaft 8, thus constructing an integrated electromagnetic clutch. This design achieves partial structural integration, effectively improving assembly convenience in confined spaces.

[0069] The above is Embodiment 1 of an integrated electromagnetic clutch provided in this application. The following is Embodiment 2 of an integrated electromagnetic clutch provided in this application. Please refer to the following for details. Figures 1 to 8 .

[0070] Based on the solution of Embodiment 1 above:

[0071] Traditional electromagnetic clutches are typically designed so that the toothed disc 61 is disengaged from the toothed clutch disc 62 when power is off. However, this design, during equipment startup or emergency power failure, may cause the toothed clutch disc 62 to disengage from the disc teeth, potentially preventing the system from maintaining its initial engagement state, thus affecting the stability and safety of the transmission. To address these issues:

[0072] Furthermore, such as Figure 2As shown, the push ring assembly 3 is designed to drive the jaw clutch 62 to separate from the toothed disc 61. Correspondingly, the reset elastic element 63 is installed between the main end cover 12 and the jaw clutch 62 to provide a reset force for the jaw clutch 62, so that the jaw clutch 62 and the toothed disc 61 engage when the coil assembly 2 is not energized. This design allows the jaw clutch 62 and the toothed disc 61 to automatically engage when the electromagnetic clutch is de-energized, ensuring that the system maintains its initial engagement state during equipment startup or emergency power failure, achieving a normally closed mode.

[0073] To reduce axial wear between the reset elastic element 63 and the main end cover 12, a second bearing 52 can be added between the reset elastic element 63 and the main end cover 12, which extends the service life of the reset elastic element 63 and the main end cover 12 and reduces maintenance costs.

[0074] Furthermore, the reset elastic element 63 is a disc spring. Disc springs possess excellent elastic properties and a compact structure, enabling them to provide sufficient reset force within a limited space. Compared to other types of springs, disc springs have higher stiffness, allowing for rapid response and the generation of a stable reset force, ensuring that the toothed disc 62 can quickly engage with the toothed disc 61 when power is off. Simultaneously, disc springs exhibit strong durability, capable of withstanding repeated compression and extension movements, reducing the probability of failure due to fatigue of the elastic element.

[0075] Furthermore, such as Figure 3 as well as Figure 4 As shown, the design of the coil assembly 2 includes an electromagnetic coil 22, a wire harness assembly 25, and a coil housing 21. The electromagnetic coil 22 is installed in the coil housing 21 and its surface is wrapped with a wrapping cloth 23. The electromagnetic coil 22 is connected to the inner wall of the coil housing 21 by a curing adhesive 24. The wire harness assembly 25 is connected to the electromagnetic coil 22. The housing ring 4 is integrally connected to the coil housing 21.

[0076] The above design allows the electromagnetic coil 22 to be stably fixed inside the coil housing 21. The wrapping cloth 23 protects the electromagnetic coil 22 from scratches or other damage during use. The bonding method of the curing adhesive 24 enhances the connection strength between the electromagnetic coil 22 and the coil housing 21, ensuring the overall stability of the coil assembly 2. The wire harness assembly 25 provides a path for the electromagnetic coil 22 to conduct electricity, ensuring its normal operation.

[0077] Furthermore, such as Figure 3As shown, the coil housing 21 includes a coil shell 211 and a coil end cap 212; the coil end cap 212 is pressed together with the coil shell 211; the shell ring 4 is welded to the coil shell 211. This pressed-to-edge connection method ensures a tight and secure connection between the coil end cap 212 and the coil shell 211. Furthermore, the shell ring 4 is welded to the coil shell 211 to achieve an integral connection, further enhancing the structural stability of the entire coil assembly 2 and ensuring that it will not loosen or shift during long-term use.

[0078] Furthermore, such as Figure 3 As shown, the push ring assembly 3 includes an inner push ring 32 and an outer push ring 31; the inner push ring 32 and the outer push ring 31 are press-fitted together; the inner push ring 32 contacts and abuts against the dental insert 62. This press-fitting method ensures a tight connection between the inner push ring 32 and the outer push ring 31, guaranteeing the overall structural strength of the push ring assembly 3. The push ring assembly 3 formed by the press-fitting of the inner push ring 32 and the outer push ring 31 can better contact the dental insert 62 and drive its movement.

[0079] During installation, first assemble the coil housing 211, electromagnetic coil 22, wrapping cloth 23, curing adhesive 24, and wire harness assembly. Then, weld the housing ring 4 to the housing. After welding, press the outer ring 31 and inner ring 32 of the push ring into a push ring assembly 3 and place it between the coil housing 211 and the housing ring 4. Finally, install the coil end cap 212 and press the coil end cap 212 to the coil housing 211 to complete the integrated structure of a coil assembly 2 and a push ring assembly 3.

[0080] Furthermore, such as Figure 5 As shown, the inner circumferential surface of the main housing 11 is provided with a limiting groove 121; a first retaining spring 13 is provided in the limiting groove 121 to provide a pressing force for the main end cover 12, so that the main end cover 12 and the main housing 11 clamp and fix the coil assembly 2.

[0081] The first retaining ring 13 ensures reliable clamping of the coil assembly 2 by the main end cover 12 and the main housing 11, preventing the coil assembly 2 from loosening or shifting during operation, thereby ensuring the overall stability and reliability of the electromagnetic clutch. During installation, the first retaining ring 13 is inserted into the limiting slot 121 to effectively fix the coil assembly 2 by the main end cover 12 and the main housing 11; the operation is simple and the fixing effect is good.

[0082] Furthermore, such as Figure 5 As shown, a flange 622 is provided on the outer peripheral surface of the dental inlay 62; the first side of the flange 622 can contact and abut against the push ring assembly 3.

[0083] The flange portion 622 allows the push ring assembly 3 to act more precisely on the dental insert 62, ensuring that the push ring assembly 3 can stably and reliably drive the dental insert 62 to move along the axial direction of the motor shaft 7, thereby achieving engagement or disengagement between the dental insert 62 and the toothed disc 61. When the push ring assembly 3 moves under the influence of a magnetic field, it contacts and abuts against the first side of the flange portion 622, transmitting the driving force to the dental insert 62, allowing the dental insert 62 to accurately approach or move away from the toothed disc 61.

[0084] Furthermore, such as Figure 5 As shown, the main end cap 12 has a first stepped portion 122; a second bearing 52 is mounted on the first stepped portion 122; the first end of the reset elastic member 63 contacts and abuts against the second bearing 52, and the second end contacts and abuts against the toothed disc 62. The installation of the second bearing 52 changes the friction between the reset elastic member 63 and the main end cap 12 from sliding friction to rolling friction when providing the reset force, greatly reducing the frictional force and further reducing the wear between the reset elastic member 63 and the main end cap 12.

[0085] Furthermore, such as Figure 5 As shown, the main housing 11 has a second stepped portion 111; a mounting gap is formed between the housing ring 4 and the second stepped portion 111; the first bearing 51 is installed in the mounting gap. This design provides a precise mounting position for the first bearing 51, ensuring stable rotational engagement between the gear disc 61 and the main housing 11 via the first bearing 51. The reasonable setting of the mounting gap allows the first bearing 51 to fit tightly with the main housing 11 and the housing ring 4, preventing the first bearing 51 from shaking or shifting during operation, thereby ensuring the stability and reliability of the gear disc 61's rotation. At the same time, this structural layout makes the internal structure of the entire electromagnetic clutch more compact.

[0086] After completing the integrated structure of coil assembly 2 and push ring assembly 3, the first bearing 51 is placed into the second step 111 of the main housing 11. Then, the integrated structure of coil assembly 2 and push ring assembly 3 is also placed into the main housing 11. Next, the gear plate 61 is placed in and installed to cooperate with the first bearing 51. Then, the toothed disc 62 is placed in and installed to cooperate with the gear plate 61. After that, the second bearing 52 and the reset elastic element 63 are placed into the first step 122 of the main end cover 12 and then cooperated with the main housing 11. Finally, the first retaining ring 13 is used to limit the installation of the main end cover 12. This completes the installation of the integrated electromagnetic core structure.

[0087] like Figure 6As shown, a third bearing 53 is interference-fitted onto the motor shaft 7 and fixed by a second retaining ring 55; while a fourth bearing 54 is interference-fitted onto the gear shaft 8. Then, the gear disc 61 is fitted to the gear shaft 8 via a splined tooth structure, and the toothed disc 62 is fitted to the motor shaft 7 via a splined tooth structure, thus achieving an integrated electromagnetic clutch.

[0088] Taking the normally closed mode design as an example, it has the following two operating states:

[0089] The first state (such as) Figure 7 As shown): This is the state after installation. The electromagnetic coil 22 is not energized, the toothed disc 62 is engaged with the toothed disc 61, and the motor shaft 7 can transmit torque with the disc tooth shaft 8. The installed first bearing 51 provides a buffer between the main housing 11 and the toothed disc 61, that is, it reduces the relative motion friction (wear) between the toothed disc 61 and the main housing 11.

[0090] The second state (such as) Figure 8 As shown): When the electromagnetic coil 22 is energized, the push ring assembly 3 pushes the toothed disc 62 axially to the third bearing 53. Since the third bearing 53 is interference-fitted with the motor shaft 7 and is limited by the second retaining spring 55 (which prevents the third bearing 53 from loosening), it restricts the axial movement of the toothed disc 62. At this time, the toothed disc 62 is disengaged from the toothed disc 61, the motor shaft 7 and the toothed disc shaft 8 do not transmit torque, and the reset elastic element 63 (disc spring) mounted on the toothed disc 62 is in a compressed state. The second bearing 52 reduces the axial wear between the reset elastic element 63 and the main end cover 12. When the electromagnetic coil 22 is de-energized, the return force of the reset elastic element 63 will push the toothed disc 62 to engage with the toothed disc 61, returning to the first state.

[0091] The above provides a detailed description of an integrated electromagnetic clutch provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
