Description

Technical Field

[0001] This utility model belongs to the field of chain technology, and specifically relates to a die-forged easy-to-disassemble chain pin. Background Technology

[0002] In transmission systems such as conveying machinery and lifting equipment, chains are a common flexible transmission component. The pins at their joints and the chain plates need to be effectively lubricated to reduce wear, lower running resistance, and extend service life. For this reason, many conveyors are equipped with automatic lubrication devices that regularly drip lubricating oil onto the chains.

[0003] However, traditional chain pins are mostly simple cylinders with a small oil-receiving area at the top, making it difficult to effectively capture and guide lubricating oil to the friction points between the shaft and the chain plate. When the lubricating oil slides down from the end, it cannot accurately and fully reach the joint gap, resulting in low lubrication efficiency. Long-term insufficient lubrication will aggravate the wear of the pin and the chain plate hole, increasing the transmission resistance. To solve the above problems, we provide a die-forged easy-to-disassemble chain pin. Utility Model Content

[0004] The purpose of this utility model is to provide a forged, easily detachable chain pin to solve the problem mentioned in the background art that traditional chain pins are mostly simple cylinders with a small oil-receiving area at the top, making it difficult to effectively capture and guide lubricating oil to the friction part between the shaft and the chain plate. When the lubricating oil slides down from the end, it cannot accurately and fully reach the joint gap, resulting in low lubrication efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a forged easy-to-disassemble chain pin, including a shaft rod, both ends of the shaft rod are integrally machined with end plates, the surface of the end plates is provided with a central ridge line, both sides of the central ridge line are integrally machined with guide surfaces, the interior of the guide surfaces is integrally machined with guide grooves, and both sides of the central ridge line are integrally machined with drainage surfaces.

[0006] Preferably, the guiding surface is a convex arc-shaped surface, and the draining surface is a concave arc-shaped surface.

[0007] Preferably, the guide surface and the drainage surface both form an inclination angle A with respect to the horizontal plane, and the inclination angle A is 5 degrees to 7 degrees.

[0008] Preferably, the guide channel forms an inclination angle B with the horizontal plane, and the inclination angle B is 35 degrees to 45 degrees.

[0009] This utility model has the following beneficial effects: This device, through the combined structure of a drainage surface, a guide surface, and a guide groove, allows lubricating oil dripping from the automatic lubrication device to increase its receiving area from the drainage surface and be guided to the guide surface. The oil then flows into the guide groove, and finally, through the guide groove, the lubricating oil is continuously and stably delivered to the shaft surface, thus achieving sufficient lubrication at the chain joints. This structure effectively improves the utilization efficiency of the lubricating oil, ensuring that the joints maintain a good oil film coverage during operation. It significantly reduces the frictional resistance and wear of the chain drive, not only improving the stability and efficiency of the conveyor's operation but also greatly extending the overall service life of the chain. It boasts advantages such as simple structure, reliable lubrication, and low maintenance costs. Attached Figure Description

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

[0013] Example 1: refer to Figure 1-3 A forged, easily detachable chain pin includes a shaft 1, with end caps 2 integrally machined at both ends of the shaft 1. The surface of the end caps 2 is provided with a central ridge 3, and guide surfaces 4 integrally machined on both sides of the central ridge 3. Guide grooves 5 are integrally machined inside the guide surfaces 4, and drainage surfaces 6 are integrally machined on both sides of the central ridge 3. The device is integrally formed by forging, and the one-piece structure enables the device to withstand higher impacts, has good fatigue resistance, and high reliability.

[0014] Specifically, the device, through the cooperative structure of the flow-guiding surface 6, the flow-directing surface 4, and the flow-directing groove 5, allows the lubricating oil dripping from the automatic lubrication device to increase the receiving area of ​​the flow-guiding surface 6 and be guided to the flow-directing surface 4. Then, the flow-directing surface 4 gathers and flows into the flow-directing groove 5, and finally, the flow-directing groove 5 continuously and stably delivers the lubricating oil to the surface of the shaft 1, thereby achieving sufficient lubrication at the chain joints. This structure effectively improves the utilization efficiency of the lubricating oil, ensures that the joints maintain good oil film coverage during operation, and significantly reduces the frictional resistance and wear of the chain drive. It not only improves the stability and efficiency of the conveying device but also greatly extends the overall service life of the chain. It has the advantages of simple structure, reliable lubrication, and low maintenance cost.

[0015] refer to Figure 1 The guide surface 4 is a convex arc surface, and the drainage surface 6 is a concave arc surface. The convex arc surface is conducive to accelerating the flow of lubricating oil, while the concave arc surface can more effectively receive the oil from the top.

[0016] refer to Figure 2 The guide surface 4 and the drain surface 6 both form an inclined angle A with the horizontal plane. The inclined angle A is 5 to 7 degrees, which allows the lubricating oil to flow smoothly and steadily on the drain surface 6 and the guide surface 4. It can catch the oil and prevent it from flowing too fast or too slow.

[0017] refer to Figure 3 The guide groove 5 forms an inclined angle B with the horizontal plane. The inclined angle B is 35 degrees to 45 degrees, which allows the lubricating oil in the guide groove 5 to rush quickly and powerfully to the surface of the shaft 1, achieving efficient lubrication and making it less likely to remain in the groove.

[0018] Brief description of usage: The chain is used in the transmission device. The conveyor is equipped with an automatic oiling device, which allows lubricating oil to drip onto the top of end 2. By setting the guide surface 6, the oil receiving area can be effectively increased, allowing the guide surface 6 to guide the lubricating oil to the guide surface 4. The guide surface 4 guides the lubricating oil into the guide groove 5, and then the lubricating oil flows through the guide groove 5 to the surface of the shaft 1 to lubricate the chain joints. This ensures the lubrication effect at the chain joints, thereby reducing running resistance, reducing wear, and extending the service life of the chain.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
