Description

Technical Field

[0001] This utility model relates to the field of mechanical transmission technology, specifically to a high-strength stainless steel chain with a corrosion-resistant coating on its surface. Background Technology

[0002] Chains are generally metal links or rings, and are mostly used for mechanical transmission and traction. Chain drives are widely used in industrial production, agricultural machinery, transportation, and engineering machinery due to their advantages such as simple structure, strong adaptability to heavy loads, and precise transmission ratio.

[0003] In industrial production, although traditional stainless steel chains have a certain strength, their surface corrosion resistance is limited in harsh environments, making them prone to rust, which affects their service life and reliability. In addition, the links of traditional chains are mostly rigidly connected, which can easily generate impact, vibration and noise during transmission, resulting in high maintenance costs. To address these issues, we have proposed a high-strength stainless steel chain with a corrosion-resistant coating on its surface. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength stainless steel chain with a corrosion-resistant coating on its surface, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pin shaft is included, with chain plates connected to both ends of the pin shaft, and rubber pads are provided on the inner side of the chain plates. A bearing is provided inside the chain plates, and a fixing plate is provided on the outer side of the chain plates, with bolts inserted into the fixing plate.

[0006] Preferably, the two sets of chain plates are movably sleeved on the pin shaft, and the chain plates are provided with slots that cooperate with the pin shaft; the chain plates sleeved on the pin shaft can stabilize the overall structure.

[0007] Preferably, a rubber pad is provided on one side of each of the two sets of chain plates, and both the front and rear sides of the rubber pad abut against the two sets of chain plates. The rubber pad is sleeved on the outside of the pin. The rubber pad can buffer the rigid collision between the chain plates and reduce the wear of the chain plates.

[0008] Preferably, the bearing is engaged at the connection between the pin and the chain plate. The chain plate has a groove for engaging the bearing. The two sets of bearings are divided into inner rings and outer rings, and the inner rings and outer rings engage with each other. The bearings are arranged in a ring structure. The bearings are arranged on the side of the two sets of bearings that are close to each other, and the bearings have grooves for placing the bearings inside. After the bearings are set, rolling friction can effectively reduce wear and improve service life.

[0009] Preferably, the fixing plate is fixed to the pin shaft by bolts, and both the fixing plate and the pin shaft are provided with slots that mate with the bolts. The fixing plate abuts against the outer side of the chain plate. The bolt connection method provides convenience for on-site maintenance and replacement of parts, reducing maintenance time and costs.

[0010] Preferably, the pin, chain plate, and fixing plate are all made of high-strength stainless steel with a corrosion-resistant coating; high-strength stainless steel can withstand high loads and impacts, thus enhancing the overall service life of the chain.

[0011] This invention provides a high-strength stainless steel chain with a corrosion-resistant coating on its surface, which has the following advantages: This solution utilizes high-strength stainless steel with a corrosion-resistant coating to enable the overall structure to withstand high loads and impacts, thereby increasing the rigidity of the chain plates, pins, and fixing plates, while also improving corrosion resistance, thus adapting to harsh working environments.

[0012] This solution achieves collision between chain plates by placing rubber pads on the front and rear sides of the chain plates, reducing wear on the chain plates. At the same time, the rubber pads act as a buffer, reducing noise generated by the chain during operation.

[0014] In the diagram: 1. Pin; 2. Rubber gasket; 3. Chain plate; 4. Bearing; 5. Fixing plate; 6. Bolt. Detailed implementation method: 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a high-strength stainless steel chain with a corrosion-resistant coating on the surface, including a pin 1, with chain plates 3 connected to both ends of the pin 1, and a rubber pad 2 provided on the inner side of the chain plate 3, a bearing 4 provided inside the chain plate 3, and a fixing plate 5 provided on the outer side of the chain plate 3, with bolts 6 inserted on the fixing plate 5.

[0016] Two sets of chain plates 3 are movably sleeved on the pin 1, and the chain plates 3 are provided with slots that cooperate with the pin 1. The movable sleeve connection allows the chain plates 3 and the pin 1 to rotate, which is the foundation of chain drive. The slots ensure that the chain plates 3 and the pin 1 avoid shaking and impact wear caused by excessive gaps, thus improving the smoothness of the transmission and the overall life of the chain.

[0017] Rubber pads 2 are provided on the adjacent side of the two sets of chain plates 3, and the front and rear sides of the rubber pads 2 abut against the two sets of chain plates 3. The rubber pads 2 are sleeved on the outside of the pin 1. The rubber pads 2 can absorb and buffer the impact and vibration generated by the chain plates 3 when they are subjected to force, reduce the rigid collision between the chain plates 3, reduce the wear between the chain plates 3, and reduce the noise of the chain when it is running.

[0018] The bearing 4 is engaged at the connection between the pin 1 and the chain plate 3. The chain plate 3 has a groove that mates with the bearing 4. The two sets of bearings 4 are divided into inner rings and outer rings, and the inner rings and outer rings engage with each other. The bearing 4 is arranged in a ring structure. The bearing 4 is located on the side of the two sets of bearings that are close to each other, and the bearing 4 has a groove inside to hold the bearing 4. The addition of the bearing 4 between the pin 1 and the chain plate 3 can improve wear resistance and efficiency, reduce the frictional resistance when the chain rotates, and reduce the wear rate by reducing the frictional force, thereby greatly extending the service life of the chain.

[0019] The fixing plate 5 is fixed to the pin 1 by bolts 6. Both the fixing plate 5 and the pin 1 have slots that mate with the bolts 6. The fixing plate 5 abuts against the outside of the chain plate 3. The combination of the fixing plate 5 and the bolts 6 can lock the chain plate 3 and bearings 4 and other components onto the pin 1 to prevent them from moving or falling off, thus ensuring the safety of the chain structure, facilitating installation and disassembly, and reducing maintenance costs and time.

[0020] Pin 1, chain plate 3, and fixing plate 5 are all made of high-strength stainless steel with corrosion-resistant coating. The high-strength material allows the chain to withstand high loads and impacts, and is not easily deformed or broken. At the same time, the corrosion-resistant coating on the surface can effectively prevent corrosion by water vapor, acids, alkalis, salts and other media, which improves the service life of the chain and expands the working conditions of the chain, making it suitable for harsh working environments.

[0021] Working principle: When the chain rotates, the bearing 4, which is engaged at the connection between the pin 1 and the chain plate 3, provides rolling friction. After rolling, the pin 1 can drive the fixing plate 5 to adjust its position, so that the pin 1 is engaged on the gear. The rubber pad 2 provides to absorb and buffer the impact and wear of the chain plate 3 when it is under force. At the same time, the rubber pad 2 can effectively reduce noise. The bolt 6 fixes the fixing plate 5 and the pin 1, making maintenance simple and convenient.
