Technical Field

[0001] The utility model relates to the technical field of transmission components, in particular to a chain transition link plate. Background Technique

[0002] The chain transition link plate is an element used in the chain drive system, usually used for the connection and transition between different types or specifications of chains.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: including an inner side link plate 1 and an outer side link plate 2. A rotation groove 3 is provided on one side of the inner side link plate 1 close to the outer side link plate 2 for installing an anti-wear ring 4 rotatably arranged in the rotation groove 3. A plurality of oil storage units 5 are connected to one side of the inner side link plate 1. There are multiple groups of oil storage units 5, which are circularly arranged along the installation holes on one side of the inner side link plate 1. The monomers in each group of oil storage units 5 are connected to an anti-wear mechanism 6. The inner side link plate 1 is rotatably connected to the outer side link plate 2 through the anti-wear mechanism 6 and the oil storage units 5;

[0024] The outer side link plate 2 includes a plate body 21. A shaft hole 23 is provided on one side of the plate body 21. The shaft hole 23, the installation hole on one side of the inner side link plate 1, and the inner ring body 61 belong to the same axis. A sealing clamping ring 22 is connected to one side of the plate body 21 close to the inner side link plate 1, which increases the fitting effect with the inner side link plate 1 during installation. While ensuring the sealing performance, it can prevent the leakage of lubricating oil. Limiting chamfers 24 for connection and wear reduction are provided on both sides of the shaft hole 23.

[0025] A fitting groove is provided on one side of the anti-wear ring 4 corresponding to the sealing clamping ring 22. The sealing clamping ring 22 is located in the fitting groove in the installation state, which plays an oil-blocking and sealing effect. The plate body 21 is rotatably connected to the oil storage unit 5 through the shaft hole 23.

[0026] The oil storage unit 5 includes a limiting frame 51. An installation groove is provided on one side of the limiting frame 51, which also has a certain oil storage effect. An airbag 52 is adhesively provided at the bottom of the installation groove. During long-term operation, heat is generated by the friction between components. After the airbag 52 is heated, it expands and squeezes the oil storage sponge 54, increasing the discharge amount of lubricating oil. A blocking frame 53 is fixedly provided at the top. When the airbag 52 squeezes the oil storage sponge 54, the blocking frame 53 can prevent the sponge from shifting and separating. As can be seen from Figure 3 , oil leakage holes are provided on the surface of the blocking frame 53, which can not only ensure the limitation of the oil storage sponge 54 but also allow the lubricating oil to seep out.

[0027] One end of the limiting frame 51 is provided with a limiting chuck 55 on the outside. The limiting chuck 55 is fitted with the limiting chamfer 24. One side of the limiting frame 51 close to each other is provided with an inclined surface. During installation, it can be installed by heating to make it have a certain elasticity, so that the limiting frame 51 penetrates through the outer chain plate 2. At the same time, the limiting chuck 55 catches the limiting chamfer 24, so as to position the outer chain plate 2 and make it rotatably connected to the inner chain plate 1 without detachment. There are multiple groups of oil storage units 5, which are fitted and connected with the anti-wear mechanism 6.

[0028] The anti-wear mechanism 6 includes an inner ring body 61. A plurality of bolts 62 are connected and arranged on the outer ring of the inner ring body 61, and are cross-fitted with each group of oil storage units 5. Ball bearings 63 are rotatably arranged on the outer surfaces of the bolts 62, and the tops of the ball bearings 63 abut against the inside of 23, playing a supporting role, ensuring the rotation effect, and reducing friction at the same time. One side of the inner ring body 61 is connected and provided with an extension pipe 64. Installation holes are correspondingly opened on both sides of the inner chain plate 1 for the extension pipe 64. As Figure 1 known, it is used for the cross shaft when installing and using the chain. There is a clearance fit between the bolt 62 and the limiting frame 51. The side of the limiting frame 51 close to each other, that is, the inner ring side, is provided with an inclined surface.

[0029] Working principle: When the utility model is in use, the extension pipe 64 is inserted into the installation hole on one side of the inner chain plate 1. At the same time, each ball bearing 63 is embedded between the oil storage units 5 to complete the connection. Then, the two ends of the inner chain plate 1 are heated. After heating, the limiting frame 51 has a certain softness. Due to the setting of the inclined surface on the inner ring of the limiting frame 51, it is convenient for slight elastic movement and allows the outer chain plate 2 to pass through. The outer chain plate 2 is sleeved on one side of the oil storage unit 5 and the anti-wear mechanism 6 through the shaft hole 23. Among them, the limiting chamfer 24 is convenient for positioning between the oil storage unit 5 and the shaft hole 23 during installation. After the limiting frame 51 penetrates through the outer chain plate 2, the limiting chuck 55 will be fitted with the limiting chamfer 24 to limit the outer chain plate 2 and prevent it from falling off. After installation, the chain shaft is installed. During use, the ball bearings 63 will abut against the inside of the shaft hole 23 to reduce wear. At the same time, the lubricating oil stored in the oil storage sponge 54 can slowly seep out to further reduce wear.
