Description

Technical Field

[0001] This utility model relates to the field of compressor parts, specifically to a high-strength compressor guide rod. Background Technology

[0002] As a core component of the compressor's transmission system, the performance of the guide rod directly determines the compressor's operational stability, reliability, and service life. Traditional compressor guide rods often employ conventional circular cross-sectional shapes and simple connection structures. Under complex operating conditions, stress concentration is prone to occur, leading to premature damage to local structures and severely affecting the normal operation of the compressor. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to provide a high-strength compressor guide link to address the problems of the prior art.

[0004] A high-strength compressor guide rod in this solution includes a rod body with an H-shaped cross-section, and the two ends of the rod body are respectively connected to a first ball head and a second ball head; the height of the rod body gradually increases towards the first ball head and gradually decreases towards the second ball head.

[0005] Furthermore, a trapezoidal transition zone is provided between the first ball head and the shaft.

[0006] Furthermore, a sloping transition zone is provided between the second ball head and the shaft.

[0007] Furthermore, the rod body includes two flanges and a web, with reinforcing ribs on both sides of the web. The reinforcing ribs are arranged in a cross pattern and are integrally connected to the flanges and the web.

[0008] Compared with existing technologies, the advantages of this solution are as follows:

[0009] The H-shaped section is used: Compared with the traditional circular section, the H-shaped section consists of two flanges and one web, which has significant advantages in resisting bending deformation and shear force, and can transfer loads more efficiently, thereby improving the overall strength and stiffness of the connecting rod.

[0010] Optimized shaft height design: The shaft height gradually increases towards the first ball head and gradually decreases towards the second ball head, which can better match the ball head diameter, optimize the overall force distribution of the connecting rod, and avoid premature damage to local structures due to uneven force distribution.

[0011] Add cross-shaped reinforcing ribs: Cross-shaped reinforcing ribs are added inside the rod body and are tightly connected to the flange and web using an integral molding process to form a stable grid-like support structure. This can effectively disperse stress and avoid structural damage caused by excessive local stress, providing a solid guarantee for the efficient and stable operation of the compressor.

[0012] Optimized connection structure: A trapezoidal transition zone is set between the first ball head and the shaft, which can effectively disperse the stress at the connection between the ball head and the shaft, avoid stress concentration, and increase the contact area with the first ball head, thereby improving the load-bearing capacity and reliability of the connection; a sloping transition zone is used between the second ball head and the shaft, which can reduce the degree of stress concentration, make the stress transition smoothly, increase the contact area with the second ball head, and ensure a stable and reliable connection.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Reference Figures 1 to 2 This diagram illustrates a high-strength compressor guide rod. The guide rod comprises a rod body 1 with an H-shaped cross-section, and a first ball joint 2 and a second ball joint 3 at each end of the rod body 1. Considering the functional differences of the different ball joints in the compressor transmission system and the different loads they bear, the height of the rod body 1 is specially designed, gradually increasing towards the first ball joint 2 and gradually decreasing towards the second ball joint 3. This design better matches the diameter of the ball joints and optimizes the overall force distribution of the link.

[0017] The H-shaped cross-section rod 1 consists of two flanges 101 and a web 102, which work together to form a stable mechanical load-bearing system. Compared with the traditional circular cross-section, the H-shaped cross-section has significant advantages in resisting bending deformation and shear force, and can transfer loads more efficiently, improving the overall strength and stiffness of the connecting rod.

[0018] To further enhance the load-bearing capacity of the rod 1 under complex working conditions, a cross-shaped reinforcing rib 6 is added inside the rod 1. This reinforcing rib 6 is tightly connected to the flange 101 and web 102 using an integral molding process, forming a stable grid-like support structure. The integral molding process ensures the connection strength between the reinforcing rib 6 and all parts of the rod 1, avoiding weak points that may arise from welding or other processes. This grid-like support structure effectively disperses stress, evenly distributing the stress generated under complex working conditions across the entire rod 1 structure, preventing structural damage caused by excessive local stress, and providing a solid guarantee for the efficient and stable operation of the compressor. In terms of material selection, the rod 1 and the reinforcing rib 6 can be made of high-strength alloy steel, with appropriate heat treatment processes further improving the material's strength, toughness, and fatigue performance.

[0019] In the connection structure design, a trapezoidal transition zone 4 is set between the first ball head 2 and the rod body 1. The upper base width of the trapezoidal transition zone 4 precisely matches the width of the flange 101 of the rod body 1, while the lower base width is slightly larger to facilitate welding with the first ball head 2. The beveled design of the trapezoid effectively disperses the stress at the connection between the ball head and the rod body 1, changes the stress transmission path, and avoids stress concentration. At the same time, the trapezoidal transition zone 4 effectively increases the contact area with the first ball head 2, resulting in a more stable connection structure after welding, thus improving the load-bearing capacity and reliability of the connection.

[0020] A sloping transition zone 5 is used between the second ball head 3 and the shaft 1. The sloping design effectively reduces stress concentration. Through a reasonable slope design, stress transitions smoothly between the ball head and the shaft 1, improving the overall reliability of the structure. Furthermore, the sloping transition zone 5 increases the contact surface with the second ball head 3, enabling a strong connection after welding, ensuring a stable and reliable connection between the ball head and the shaft 1 under complex working conditions.

[0021] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
