Description

Technical Field

[0001] This utility model belongs to the field of chain drive technology, specifically relating to a magnetically coupled buffer chain. Background Technology

[0002] Chain meshing impact refers to the mechanical collision that occurs when the rollers (or bushings) of the chain contact and engage with the teeth of the sprocket, due to the relative speed difference between the two. Existing measures to reduce meshing impact include: 1. increasing the number of sprocket teeth; 2. reducing the chain pitch; 3. controlling chain tension; 4. using sprockets with optimized tooth profiles; 5. using high-quality chains; and 6. proper lubrication. However, increasing the number of sprocket teeth increases space requirements and costs; reducing the chain pitch requires using multiple rows of small-pitch chains instead of a single row of large-pitch chains; and excessive chain tension can increase wear and load. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model proposes a magnetically coupled buffer chain, in which adjacent outer chain plates attract each other to achieve the purpose of buffering meshing impact and reducing wear.

[0004] The technical solution adopted in this utility model is: A magnetically coupled buffer chain includes outer chain plates, inner chain plates, pins, rollers, and sleeves. Two outer chain plates and two pins are tightly fitted together to form an outer chain link. Two inner chain plates and two sleeves are combined to form an inner chain link. The inner chain link is located between the two outer chain plates of the outer chain link. The sleeve is sleeved outside the pins. The roller is sleeved outside the sleeve and located between the two inner chain plates. Strong magnets are installed at both ends of the outer chain plates. The strong magnets on adjacent outer chain plates have opposite magnetic properties on opposite sides.

[0005] Furthermore, it also includes connecting chain plates, two connecting chain plates and two connecting pins are tightly fitted together to form a connecting outer chain link, one of which is inserted through the inner chain link.

[0006] Furthermore, the two connecting pins are connected on their outer sides by an elastic locking plate.

[0007] Furthermore, strong magnets are installed at both ends of the connecting chain plate, and the strong magnets on the connecting chain plate have opposite magnetic properties to the strong magnets on the adjacent outer chain plate.

[0008] Furthermore, both ends of the outer chain plate and the connecting chain plate are provided with outward protrusions, and the strong magnet is installed at the extension.

[0009] Furthermore, the strong magnet is embedded in the extension.

[0010] Furthermore, the height of the extension is greater than the height of the pin protruding from the outer chain plate.

[0011] Furthermore, the width of the extension is less than the thickness of the outer chain plate.

[0012] Furthermore, the length of the extension is greater than the diameter of the pin hole on the outer chain plate but less than the diameter of the outer circle on the outer chain plate.

[0013] Furthermore, the two ends of the sleeve protrude from the end face of the inner chain plate.

[0014] The beneficial effects of this utility model are: adjacent outer chain plates attract each other, thereby buffering the meshing impact and reducing wear. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] See Figure 1-4This embodiment provides a magnetically coupled buffer chain, including an outer chain plate 1, an inner chain plate 2, a pin 4, a roller 5, and a sleeve 3. Two outer chain plates 1 and two pins 4 are tightly fitted together to form an outer chain link. Two inner chain plates 2 and two sleeves 3 are combined to form an inner chain link. The inner chain link is located between the two outer chain plates 1 of the outer chain link. The sleeve 3 is sleeved outside the pin 4. The two ends of the sleeve 3 protrude from the end faces of the inner chain plates 2. The roller 5 is sleeved outside the sleeve 3 and located between the two inner chain plates 2. Strong magnets 9 are installed at both ends of the outer chain plates 1. The strong magnets 9 on adjacent outer chain plates 1 have opposite magnetic properties on opposite sides, thereby achieving mutual attraction.

[0025] This embodiment of a magnetically coupled buffer chain also includes connecting chain plates 7. Two connecting chain plates 7 are tightly fitted with two connecting pins 6 to form connecting outer chain links, one of which is inserted through an inner chain link. The two connecting pins 6 are connected by elastic locking plates 8 on their outer sides. Strong magnets 9 are installed at both ends of the connecting chain plates 7. The strong magnets 9 on the connecting chain plates 7 have opposite magnetic properties to the strong magnets 9 on the adjacent outer chain plates 1, thereby achieving mutual attraction.

[0026] In this embodiment, both ends of the outer link plate 1 and the connecting link plate 7 have outwardly protruding extension portions 10, and the strong magnet 9 is installed at the extension portion 10. The extension portion 10 is perpendicular to the link plate body. The strong magnet 9 can be embedded in the extension portion 10. The height of the extension portion 10 is greater than the height of the pin 4 protruding from the outer link plate 1, its width is less than the thickness of the outer link plate 1, and its length is greater than the diameter of the pin hole on the outer link plate 1 but less than the diameter of the outer circle on the outer link plate 1.

[0027] In this embodiment, the strong magnet 9 can be a neodymium iron boron magnet with an N pole on one side and an S pole on the other. Its volume can be made smaller and the cost is relatively low. It can be formed by sintering, bonding or injection molding.

[0028] In use, this utility model uses the magnetic coupling of strong magnets 9 on the outer chain plate 1 to attract each other, reducing instantaneous impact, thereby achieving the purpose of buffering meshing impact and reducing wear.
