[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] This embodiment discloses a high-strength, deformation-resistant transmission chain, such as... Figures 1 to 3 As shown, this utility model has the effect of high strength and includes an inner chain plate 1, an outer chain plate 2, a pin 3, a sleeve 4, and rollers 5. The outer chain plate 2 is fixedly connected to the pin 3; the inner chain plate 1 is fixedly connected to the sleeve 4; the pin 3 is located on the sleeve 4 and is clearance-fitted with the sleeve 4; the outer side of the sleeve 4 has rollers 5 that are clearance-fitted with the sleeve 4; one end of the pin 3 is stepped; an oil storage groove 6 is provided on the sleeve 4; the oil storage grooves 6 are interconnected; and a side plate 7 is fixedly provided on the outer side of the outer chain plate 2 and is fixedly connected to the outer chain plate 2.

[0014] By adopting the above technical solution: the inner chain plate 1 and the sleeve 4 are interference-fitted, the outer chain plate 2 and the pin 3 are interference-fitted, and one end of the pin 3 is stepped, which can prevent the outer chain plate 2 and the side plate 7 from separating from the pin 3 through the stepped end of the pin 3; when external lubricating oil enters between the sleeve 4 and the roller 5, the oil storage tank 6 is set so that the lubricating oil can be temporarily stored in the oil storage tank 6, and the oil storage tanks 6 are interconnected, which further increases the storage time of the lubricating oil between the sleeve 4 and the pin 3. By giving the pin 3 and the sleeve 4 sufficient lubrication, the friction between the two can be reduced, thereby indirectly improving the strength between the sleeve 4 and the pin 3, and thus improving the strength of the chain.

[0015] By setting a side plate 7 on the outer chain plate 2, the overall strength of the outer chain plate 2 can be increased, thereby making the chain stronger.

[0016] like Figure 1 , Figure 2 As shown, the side plate 7 is fixedly connected to the outer chain plate 2; the outer chain plate 2 and the side plate 7 are provided with plate holes 8; after the pin 3 passes through the plate hole 8, the other end of the pin 3 is fixedly connected to the connector 9 which is provided with a through hole; the connector 9 is located on the side away from the pin 3 and is stepped.

[0017] By adopting the above technical solution: by setting a side plate 7 on one side of the outer chain plate 2, the overall strength of the outer chain plate 2 can be strengthened. The pin 3 and the plate hole 8 are interference fit, so that the pin 3 is stably set between the outer chain plate 2 and the side plate 7. Then, the through hole of the connector 9 is welded to the pin 3 so that both ends of the pin 3 are stepped.

[0018] like Figure 1 , Figure 2 As shown, the outer chain plate 2 is provided with a protruding rod 10; the side plate 7 is provided with a groove 11; the protruding rod 10 is fixedly connected to the groove 11.

[0019] By adopting the above technical solution, the protruding rod 10 and the groove 11 are connected by welding. The protruding rod 10 and the groove 11 can increase the contact area between the outer chain plate 2 and the side plate 7, thereby making the connection between the outer chain plate 2 and the side plate 7 more stable.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, the sleeve 4 is provided with a pipe groove 12 that connects the oil storage tank 6 with the oil storage tank 6 and the oil storage tank 6 with the outside.

[0021] By adopting the above technical solution, the pipe groove 12 can connect the oil storage tank 6 and the oil storage tank 6, thereby enabling the lubricating oil between the oil storage tanks 6 to flow to each other, and the pipe groove 12 at the top and bottom of the sleeve 4 facilitates the entry of external lubricating oil into the oil storage tank 6 through the pipe groove 12 at the top and bottom.

[0022] The inner chain plate 1, outer chain plate 2, pin 3, sleeve 4, and roller 5 all have a galvanized layer on their outer sides.

[0023] By adopting the above technical solution, the inner chain plate 1, outer chain plate 2, pin 3, sleeve 4, and roller 5 are all galvanized, which can enhance the corrosion resistance, rust prevention, and tensile strength of each component, thereby improving the overall strength of the chain.

[0024] In summary, this utility model has the following beneficial effects: the side plate 7 provided on the outer chain plate 2 can strengthen the overall strength of the outer chain plate 2 and the side plate 7, thereby improving the overall strength of the chain; when external lubricating oil lubricates the chain, the lubricating oil can increase the contact time between the lubricating oil and the sleeve 4 and the pin 3 through the oil storage tank 6 when it enters between the sleeve 4 and the pin 3. The lubricating oil can be temporarily stored in the oil storage tank 6 and the oil storage tanks 6 are interconnected, further increasing the storage time of the lubricating oil between the sleeve 4 and the pin 3. By providing sufficient lubrication to the pin 3 and the sleeve 4, the friction between the two can be reduced, thereby indirectly improving the strength between the sleeve 4 and the pin 3.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
