Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, specifically to the fast-response coil structure of an electromagnetic clutch. Background Technology

[0002] The fast-response coil of an electromagnetic clutch is a key component for achieving the clutch's rapid engagement and disengagement function. In practical applications, several problems are typically encountered. For example, during power transmission, the fast-response coil may be subjected to vibration, external impact, or other factors, leading to collisions between components and causing damage, affecting the clutch's normal operation and lifespan. Furthermore, when the power transmission state changes, components related to the fast-response coil may disengage, causing power transmission interruption and reducing the stability and reliability of the equipment.

[0003] In the electromagnetic jaw clutch structure disclosed in prior art document CN207961326U, an electromagnetic field is generated by energizing a coil assembly to drive the push ring assembly, thereby achieving the engagement and disengagement of the clutch's primary and secondary gears, which solves the clutch control problem to some extent. However, in actual operation, when the equipment encounters vibration, impact, or other conditions, the fast-response coil may collide with other components due to a lack of effective protection, leading to component damage. This compromises the integrity of the clutch's internal structure, making it difficult to maintain its normal power transmission function. This increases maintenance costs and replacement frequency, affecting the long-term stable operation of the equipment.

[0004] Therefore, in order to address the shortcomings of the existing technology, a fast-response coil structure for an electromagnetic clutch was proposed. Utility Model Content

[0005] The purpose of this invention is to provide a fast-response coil structure for an electromagnetic clutch to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fast-response coil structure for an electromagnetic clutch, comprising: a connecting pivot, an anti-collision mechanism, and an anti-disengagement mechanism, wherein an upper clutch housing is disposed outside the connecting pivot, a coil body is disposed at the bottom of the upper clutch housing, a middle connecting shaft is disposed in the middle of the upper clutch housing, and a clutch bottom housing is disposed at the bottom of the middle connecting shaft.

[0007] The anti-collision mechanism is used to prevent the coil body from impacting the inside of the clutch bottom housing;

[0008] The anti-detachment mechanism prevents the coil body from detaching from the upper end of the central coupling.

[0009] Furthermore, the anti-collision mechanism includes a limiting arc plate, a positioning fan plate, and a hook. The inner side of the clutch bottom shell is provided with a limiting arc plate in an annular shape. The lower end of the outer side of the limiting arc plate is symmetrically fitted with a positioning fan plate. The connection between the positioning fan plate and the two sides of the limiting arc plate is provided with a hook.

[0010] Furthermore, the end of the hook has a wedge-shaped structure.

[0011] Furthermore, the positioning fan blade has a fan-shaped structure, and the limiting arc blade has an arc-shaped structure.

[0012] Furthermore, the anti-detachment mechanism includes a gear shaft, a convex piece, an anti-detachment curved piece, and a guide rod. The gear shaft is inserted inside the central coupling. A convex piece is fixed in a ring at the groove outside the gear shaft. A guide rod is arranged laterally at the middle of the outer side of the convex piece. An anti-detachment curved piece is inserted outside the guide rod.

[0013] Furthermore, the edge of the bottom end of the anti-detachment plate extends beyond the outer edge of the bottom end of the coil body.

[0014] Furthermore, the anti-detachment plate has two sides that curve upwards to one side, and the upper part of the anti-detachment plate extends between the inner side of the coil body and the outer side of the central coupling, and the anti-detachment plate and the guide rod will not rotate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the coordinated operation of the limiting arc plate, positioning fan plate, and hook on the inner side of the clutch bottom housing. When the coil body may impact the clutch bottom housing during movement, the limiting arc plate provides annular blocking, the positioning fan plate provides assistance, and the wedge-shaped structure of the hook disperses stress. This can prevent damage to components caused by impact, reduce maintenance costs and replacement frequency, ensure the integrity of the internal structure of the clutch, maintain its normal power transmission function, extend the overall service life, ensure long-term stable operation of the equipment, and reduce the risk of downtime due to component damage.

[0017] 2. This utility model utilizes the cooperation of the internal gear shaft of the central coupling, the cam, the guide rod, and the anti-detachment curved plate. When the coil body is subjected to an upward force and tends to detach, the anti-detachment curved plate, connected to the cam through the guide rod, plays a role in supporting the coil body at its bottom and restricting its movement at its sides and top, preventing the coil body from detaching from the upper end of the central coupling, ensuring the continuity of power transmission, avoiding power interruption due to component detachment, improving the reliability of equipment operation, reducing the probability of failure, and facilitating continuous and efficient operation of the equipment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-6 As shown, the fast response coil structure of the electromagnetic clutch includes: a connecting pivot 1, an anti-collision mechanism and an anti-disengagement mechanism. The upper clutch housing 2 is provided outside the connecting pivot 1. The coil body 3 is provided at the bottom of the upper clutch housing 2. The middle connecting shaft 7 is provided in the middle of the upper clutch housing 2. The bottom of the middle connecting shaft 7 is provided with the clutch bottom housing 6.

[0027] The anti-collision mechanism is used to prevent the coil body 3 from impacting the inside of the clutch bottom housing 6;

[0028] The anti-detachment mechanism prevents the coil body 3 from detaching from the upper end of the central coupling 7.

[0029] The anti-collision mechanism includes a limiting arc plate 5, a positioning fan plate 8, and a hook part 11. The limiting arc plate 5 is arranged in a ring on the inner side of the clutch bottom shell 6. The positioning fan plate 8 is symmetrically attached to the lower end of the outer side of the limiting arc plate 5. The hook part 11 is provided at the connection between the positioning fan plate 8 and the two sides of the limiting arc plate 5.

[0030] The anti-detachment mechanism includes a gear shaft 9, a protrusion 10, an anti-detachment curved plate 4, and a guide rod 12. The gear shaft 9 is inserted inside the central coupling 7. The protrusion 10 is fixed in a ring at the groove outside the gear shaft 9. The guide rod 12 is arranged horizontally at the middle of the outside of the protrusion 10. The anti-detachment curved plate 4 is inserted outside the guide rod 12.

[0031] The rest are as follows: When the car starts, the engine runs and the power is transmitted to the clutch through the connecting pivot 1. The connecting pivot 1 drives the upper clutch housing 2 to rotate, which in turn causes the coil body 3 to rotate. When the car encounters bumpy road conditions during driving, the chassis vibrates, which may cause the clutch components to shift. At this time, the anti-collision mechanism comes into play. The limiting arc plate 5 on the inner side of the clutch bottom housing 6, due to its ring-shaped arrangement, can block the coil body 3 from multiple directions to prevent it from moving down too far and hitting the clutch bottom housing 6. The positioning fan plate 8 further assists the limiting arc plate 5 to enhance the blocking effect. The wedge-shaped structure of the hook 11 can effectively disperse the impact stress caused by vibration and avoid damage to the components.

[0032] When a car shifts gears, the electromagnetic clutch needs to respond quickly and transmit power accurately. At this time, the anti-disengagement mechanism is crucial. The gear shaft 9 inside the central coupling 7 rotates with the power transmission. The cam 10 is fixedly connected to the guide rod 12. The anti-disengagement curved plate 4 is inserted into the guide rod 12. At the moment of gear shifting, the power transmission state changes, and the coil body 3 may be subjected to an upward force and tend to disengage from the central coupling 7. Because the bottom end of the anti-disengagement curved plate 4 extends beyond the outer edge of the bottom end of the coil body 3, it can support the coil body 3 from below. At the same time, the sides are raised and the top extends to a specific position, restricting the movement of the coil body 3 in multiple directions, ensuring that it will not disengage from the top of the central coupling 7, ensuring the stability and continuity of power transmission during the gear shifting process, making the car drive more smoothly, and reducing the impact and wear of power interruption on components such as the transmission.

[0033] After the material conveying equipment is started, the power source transmits power to the clutch through the connecting pivot 1. The connecting pivot 1 drives the upper housing 2 of the clutch and the coil body 3 at the bottom to start running. During the operation of the production line, the conveying equipment may vibrate due to uneven material accumulation, which may cause the coil body 3 to collide with the clutch bottom housing 6. At this time, the limiting arc plate 5 in the anti-collision mechanism will limit the downward movement of the coil body 3. Its ring layout can play a blocking role in all directions. The positioning fan plate 8 works with the limiting arc plate 5 to further enhance the blocking effect. The wedge structure of the hook 11 can effectively cope with the impact force brought by the vibration, protect the parts from damage, maintain the normal operation of the equipment, and avoid the production line from stopping due to the damage of the parts, thus affecting the production progress.

[0034] When the material conveying equipment needs to start, stop, or change conveying speed, the electromagnetic clutch must respond accurately. The anti-detachment mechanism plays a key role in this process. The gear shaft 9 inside the central coupling 7 rotates with the change of power. The cam 10 and the guide rod 12 remain relatively fixed. The anti-detachment curved plate 4 is installed on the guide rod 12. When the equipment starts, stops, or changes speed, the sudden change in power may cause the coil body 3 to be subjected to an upward force. With its unique structure, the anti-detachment curved plate 4 supports the coil body 3 from below and restricts it in multiple directions, preventing it from detaching from the upper end of the central coupling 7. This ensures that the clutch can stably transmit power under different working conditions, enabling the material conveying equipment to start, stop, and change speed accurately according to production needs, improving the automation level and production efficiency of the production line, reducing manual intervention, and lowering production costs.

[0035] Working principle: When using the fast response coil structure of this electromagnetic clutch, the connecting pivot 1 first serves as the starting component for power input, receiving power from an external power source. The connecting pivot 1 is connected to the upper clutch housing 2. When power is transmitted to the connecting pivot 1, it drives the upper clutch housing 2 to rotate together. The coil body 3 set at the bottom of the upper clutch housing 2 also rotates when the upper clutch housing 2 rotates. The intermediate connecting shaft 7 is located in the middle position inside the upper clutch housing 2, and its bottom is connected to the clutch bottom housing 6, playing a key intermediate connection role in the entire power transmission process.

[0036] The main function of the anti-collision mechanism is to prevent the coil body 3 from impacting the inside of the clutch bottom shell 6. The clutch bottom shell 6 is provided with a limiting arc plate 5 in an annular shape. The positioning fan plate 8 is symmetrically mounted on the lower end of the outer side of the limiting arc plate 5, and there is a hook 11 at the connection between the two. The end of the hook 11 is a wedge-shaped structure. The positioning fan plate 8 is fan-shaped, and the limiting arc plate 5 is arc-shaped.

[0037] When the coil body 3 moves downward with the upper clutch housing 2 and may collide with the clutch bottom housing 6, the limiting arc plate 5 first acts as a blocking agent. Since it is arranged in a ring inside the clutch bottom housing 6, it can limit the excessive downward movement of the coil body 3 from the circumferential direction. The positioning fan plate 8 assists the limiting arc plate 5 to further enhance the blocking effect. The wedge-shaped structure of the hook 11 can better withstand and disperse stress when subjected to impact force, avoid damage to components, and thus effectively prevent the coil body 3 from impacting the inside of the clutch bottom housing 6.

[0038] The anti-detachment mechanism is used to prevent the coil body 3 from detaching from the upper end of the central coupling 7. A gear shaft 9 is inserted inside the central coupling 7. A ring-shaped protrusion 10 is fixed at the groove outside the gear shaft 9. A guide rod 12 is arranged horizontally in the middle of the protrusion 10. An anti-detachment curved piece 4 is inserted outside the guide rod 12. The bottom edge of the anti-detachment curved piece 4 extends beyond the bottom outer edge of the coil body 3. Both sides are raised to one side, and the upper part extends to the inner side of the coil body 3 and the outer side of the central coupling 7, and does not rotate with the guide rod 12.

[0039] When the coil body 3 is subjected to an upward force during operation and tends to detach from the upper end of the central coupling 7, the anti-detachment plate 4 comes into play. The anti-detachment plate 4 is connected to the convex plate 10 through the guide rod 12. Due to its positional relationship, it can block the coil body 3. Its bottom end extends beyond the outer edge of the bottom end of the coil body 3 and can support the coil body 3 from below. The two sides are raised and the upper end extends to a specific position, which restricts the movement of the coil body 3 in multiple directions, thereby effectively preventing the coil body 3 from detaching from the upper end of the central coupling 7 and ensuring the stability and reliability of the entire electromagnetic clutch fast response coil structure.
