Description

Technical Field

[0001] This utility model relates to the field of shaft coupling technology, and in particular to a highly reliable input shaft coupling structure. Background Technology

[0002] In mechanical transmission systems, the connection between the input shaft and the power shaft is a crucial link in ensuring the efficient and stable operation of the system. With the increasing demands for industrial automation and high-precision equipment, traditional connection methods often fail to meet the requirements of high reliability and long-term stability when facing high loads, vibrations, and changes in the external environment. Therefore, developing an input shaft coupling structure that is highly reliable, wear-resistant, vibration-resistant, and effectively prevents loosening has become an important technical requirement for improving the working efficiency and service life of mechanical systems.

[0003] Currently, traditional input shaft coupling structures mostly use simple connecting bolts and sleeves. This structure typically has the following drawbacks: 1. Unstable power transmission: Under high loads or prolonged use, traditional structures are prone to loosening and accelerated wear, leading to decreased power transmission efficiency and affecting the overall performance of the mechanical system; 2. Poor vibration resistance: In working environments with significant vibration or impact, the connecting parts of traditional structures are prone to loosening or damage, causing equipment failure or downtime and reducing production efficiency; 3. Lack of effective protection: Many traditional structures lack sufficient protective design, allowing external contaminants, dust, and dirt to easily enter the connecting parts, leading to problems such as damage to the lubricating oil film and corrosion of components, further affecting the operational stability of the equipment.

[0004] Therefore, it is essential to invent a highly reliable input shaft coupling structure. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a highly reliable input shaft coupling structure, solving the issues of unstable power transmission, poor vibration resistance, and lack of effective protection inherent in existing shaft coupling structures. A highly reliable input shaft coupling structure includes an input shaft, a power shaft, a connecting key, coupling nodes, coupling bolts, protective pads, and an anti-detachment housing. The connecting key is embedded on the outer side of the input shaft and the power shaft, and the coupling nodes are installed on the outer side of the input shaft, the power shaft, and the connecting key. These coupling nodes are connected together by coupling bolts. The protective pads are disposed between the two sets of coupling nodes and between the input shaft and the power shaft. The anti-detachment housing is fixedly installed on the outer side of the two sets of coupling nodes.

[0006] The protective pad includes a node pad, a clearance pad, an outer sealing ring, and a shaft pad. The clearance pad is installed in the middle of the node pad, and the outer sealing ring is installed on the outside of the node pad. The shaft pad is located at the center of the node pad. The node pad and the clearance pad are located between two sets of connecting nodes. The outer sealing ring covers the outside of the joint between the two sets of connecting nodes. The shaft pad is located between the input shaft and the power shaft.

[0007] The anti-detachment shell includes a wrapping shell with a clearance slot, a connecting shell, and a fixing bolt. The clearance slot is formed on the inner wall of the wrapping shell, and the connecting shell is fixedly installed on the outer side of the center position of the wrapping shell. The connecting shell is installed on the outer side of the coupling node by the fixing bolt. The wrapping shell wraps around the outer side of the coupling node. The clearance slot wraps around the outer side of the coupling bolt.

[0008] The node pads and clearance pads inside the protective pad are made of round, rigid rubber, and the thickness of the node pads and clearance pads is 1mm. The shape of the node pads and clearance pads is consistent with the gap between the two sets of connecting nodes. The outer sealing ring is a set of annular rubber rings, and the outer sealing ring is elastic. The shaft pad is sandwiched between the input shaft and the power shaft, and the shaft pad is made of rigid rubber with a thickness of 1mm.

[0009] The anti-detachment shell uses two sets of mirror-image stainless steel metal structures, and the anti-detachment shell is pressed inward close to the coupling node by the pressure of the fixing bolts. The size of the clearance slot matches the coupling bolt.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The protective pad of this utility model has the following functions: ① Reduces wear and vibration: By being placed between the two sets of coupling nodes and between the input shaft and the power shaft, the protective pad effectively reduces the direct friction between them, thereby reducing wear. It can also absorb a certain amount of vibration and maintain the stability of the structure; ② Provides sealing protection: The outer sealing ring of the protective pad covers the outside of the joint of the two sets of coupling nodes, playing a sealing role and preventing dust, impurities, etc. from entering the connection area, while maintaining the integrity of the lubricating oil or lubricant; ③ Prevents external damage: Due to its structural design, the protective pad can provide a certain degree of protection for the coupling nodes, preventing external impact or physical damage and extending the service life of the system.

[0012] 2. The anti-detachment shell of this utility model has the following functions: ① Preventing the coupling nodes from falling off:

[0013] The anti-detachment housing wraps around the outside of the coupling node and presses it inward with the pressure of the fixing bolts, ensuring that it will not fall off during operation due to vibration, load, or external forces. This improves the overall reliability and safety of the structure; ② Enhances structural stability: The metal structure of the anti-detachment housing, especially the combination of the outer shell and the connecting shell, provides additional support and protection in the connection area, preventing deformation or damage caused by external forces; ③ Protects the coupling bolts: The clearance slots on the anti-detachment housing precisely match the coupling bolts, ensuring that the coupling bolts will not loosen or fall off due to external forces, thereby guaranteeing the firmness and safety of the connection.

[0014] 3. This utility model presents a highly reliable input shaft coupling structure. Through a robust connection between the input shaft and the power shaft, it ensures efficient power transmission and enhances the stability and reliability of the system. The precise design of the connecting key, coupling node, and coupling bolts, combined with the protection of protective pads and an anti-detachment housing, prevents loosening, wear, and the intrusion of external contaminants, effectively extending the structure's service life. Its metal housing provides impact resistance and high load capacity, ensuring long-term stable operation of the system even under severe vibration and high load environments, thereby improving the overall system's safety and reliability. It is widely used in mechanical transmission systems requiring high precision and high stability. Attached Figure Description
