A horizontal vibration isolator containing a spring

Abstract

The horizontal vibration isolator with spring comprises a top cover, an intermediate connecting mechanism, a base and a transverse shear force elimination unit arranged between the top cover and the intermediate connecting mechanism and between the intermediate connecting mechanism and the base respectively. The transverse shear force elimination unit comprises a plurality of identical transverse shear force elimination devices, each of which comprises a spring, a hollow connecting mechanism and a rod connecting mechanism. The two ends of the spring are fixedly connected with the hollow connecting mechanism and the rod connecting mechanism respectively. A metal rod is arranged at the center of the rod connecting mechanism and is in transition fit with the hollow connecting mechanism. The horizontal vibration isolator with spring has the characteristics of high-efficiency shear force elimination, multi-point distribution symmetry, compact structure, convenient installation and strong versatility. Through the synergistic effect of the spring and the transition-fitted metal rod, the transverse vibration is converted into the axial compression / tension force of the spring, so that the transverse vibration is avoided from being directly transmitted to the structure body.

Description

Technical Field

[0001] This invention relates to the field of vibration isolation, specifically to a horizontal vibration isolator containing a spring, suitable for horizontal vibration under multi-directional planar force coupling conditions. Background Technology

[0002] In precision machinery, aerospace, and heavy equipment systems, eliminating horizontal vibration while transmitting axial force is a key factor in mechanical design under specific conditions. Traditional structures often fail to effectively eliminate horizontal vibration, leading to additional stress during equipment use, reduced reliability, and accelerated component wear. Existing horizontal vibration isolation devices often rely on complex mechanical structures or materials like rubber, but these suffer from structural redundancy, large installation space requirements, and lag in dynamic response. Furthermore, existing devices struggle to ensure symmetrical force transmission when distributed at multiple points, easily causing localized stress concentrations. Therefore, there is an urgent need for a compact, symmetrically force-transmitting horizontal vibration isolator that can adapt to multi-point distribution. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a horizontal vibration isolator containing a spring. Through the synergistic effect of the spring and the transition fit structure, vibration control is achieved while ensuring symmetrical force transmission in multi-point distribution scenarios. The technical solution of this invention is as follows:

[0005] The transverse shear force elimination unit includes multiple identical transverse shear force elimination devices. Each transverse shear force elimination device includes a spring 24, a hollow connecting mechanism 25, and a rod connecting mechanism 26. The two ends of the spring 24 are respectively fixed to the hollow connecting mechanism 25 and the rod connecting mechanism 26. The rod connecting mechanism 26 contains a metal rod at its center, which transitionally engages with the hollow connecting mechanism 25.

[0006] Furthermore, the intermediate connecting mechanism 4 has multiple grooves, each groove containing a through hole, and the through holes are vertically aligned vertically.

[0007] Furthermore, the number of the transverse shear force relief devices is 4-16.

[0008] Furthermore, there are 12 transverse shear force elimination devices, specifically: a first transverse shear force elimination device 12, a second transverse shear force elimination device 13, a third transverse shear force elimination device 14, a fourth transverse shear force elimination device 15, a fifth transverse shear force elimination device 16, a sixth transverse shear force elimination device 17, a seventh transverse shear force elimination device 18, an eighth transverse shear force elimination device 19, a ninth transverse shear force elimination device 20, a tenth transverse shear force elimination device 21, an eleventh transverse shear force elimination device 22, and a twelfth transverse shear force elimination device 23.

[0009] Furthermore, the top ends of the first transverse shear force elimination device 12, the fifth transverse shear force elimination device 16, and the sixth transverse shear force elimination device 17 are disposed in the groove of the top cover 1 and are fixedly connected to the top cover 1 through the first top connecting shaft 2. The top ends of the second transverse shear force elimination device 13, the third transverse shear force elimination device 14, and the fourth transverse shear force elimination device 15 are disposed in the groove of the top cover 1 and are fixedly connected to the top cover 1 through the second top connecting shaft 3.

[0010] Furthermore, the bottom ends of the first transverse shear force elimination device 12, the fifth transverse shear force elimination device 16, and the sixth transverse shear force elimination device 17 are disposed in the upper groove of the intermediate connecting mechanism 4, and are fixedly connected to the intermediate connecting mechanism 4 through the upper middle first connecting shaft 5; the bottom ends of the second transverse shear force elimination device 13, the third transverse shear force elimination device 14, and the fourth transverse shear force elimination device 15 are disposed in the upper groove of the intermediate connecting mechanism 4, and are fixedly connected to the intermediate connecting mechanism 4 through the second upper middle connecting shaft 6.

[0011] Furthermore, the top ends of the seventh transverse shear force eliminator 18, the eighth transverse shear force eliminator 19, and the ninth transverse shear force eliminator 20 are disposed in the lower groove of the intermediate connecting mechanism 4, and are fixedly connected to the intermediate connecting mechanism 4 via the first lower intermediate connecting shaft 7. The top ends of the tenth transverse shear force eliminator 21, the eleventh transverse shear force eliminator 22, and the twelfth transverse shear force eliminator 23 are disposed in the lower groove of the intermediate connecting mechanism 4, and are fixedly connected to the intermediate connecting mechanism 4 via the second lower intermediate connecting shaft 8.

[0012] Furthermore, the bottom ends of the seventh transverse shear force elimination device 18, the eighth transverse shear force elimination device 19, and the ninth transverse shear force elimination device 20 are set in the groove of the base 11 and are fixedly connected to the base 11 through the first base connecting shaft 9; the bottom ends of the tenth transverse shear force elimination device 21, the eleventh transverse shear force elimination device 22, and the twelfth transverse shear force elimination device 23 are set in the groove of the base 11 and are fixedly connected to the base 11 through the second base connecting shaft 10.

[0014] Beneficial effects

[0015] The spring-loaded horizontal vibration isolator of this invention features efficient shear force elimination, symmetrical multi-point distribution, compact structure, convenient installation, and strong versatility. Through the synergistic action of the spring and the transition-fitted metal rod, lateral vibration is converted into axial compression / tension force of the spring, preventing direct transmission of lateral vibration to the main structure and eliminating the impact of vibration on the mechanical system, while ensuring the transmission of axial force. The lateral shear force elimination device is symmetrically distributed along the central axis of the top and base, effectively ensuring a symmetrical force transmission path, avoiding local stress concentration, and improving system stability. The combination of grooves and through holes, along with the grouped fixing of the top / middle / base connecting shafts, enables rapid positioning and assembly, reducing installation errors. This invention is applicable to systems in different application environments and can adapt to different load conditions without requiring additional structural adjustments.

During installation, the spring can be pre-compressed to generate a preload. The metal rod at the center of the rod-connecting mechanism 26 and the hollow connecting mechanism 25 are fitted with an intermediate fit to ensure that the spring 24 only bears axial force during lateral force transmission, thus avoiding shear stress.

[0028] The intermediate connecting mechanism 4 has multiple grooves, each containing a through hole, and the through holes are vertically aligned. The same number of grooves are provided at the top and bottom, and the upper and lower grooves are symmetrical along their respective central axes.

[0029] Preferably, the number of transverse shear force relief devices can be 4-16, which can be increased or decreased as needed to meet actual requirements.

[0030] Example

[0031] This implementation example Figure 3 As shown, there are 12 transverse shear force relief devices, which can be divided into two groups:

[0032] The first group consists of six transverse shear force elimination devices between the top cover 1 and the intermediate connecting mechanism 4, namely the first transverse shear force elimination device 12, the second transverse shear force elimination device 13, the third transverse shear force elimination device 14, the fourth transverse shear force elimination device 15, the fifth transverse shear force elimination device 16, and the sixth transverse shear force elimination device 17.

[0033] The second group consists of six transverse shear force elimination devices between the intermediate connecting mechanism 4 and the base 11, namely the seventh transverse shear force elimination device 18, the eighth transverse shear force elimination device 19, the ninth transverse shear force elimination device 20, the tenth transverse shear force elimination device 21, the eleventh transverse shear force elimination device 22, and the twelfth transverse shear force elimination device 23.

[0034] The top cover 1 has 6 symmetrical grooves, and through holes are opened in the grooves. The top ends of the first transverse shear force elimination device 12, the fifth transverse shear force elimination device 16, and the sixth transverse shear force elimination device 17 are embedded in the grooves of the top cover 1 and are fixedly connected by the first top connecting shaft 2; the top ends of the second transverse shear force elimination device 13, the third transverse shear force elimination device 14, and the fourth transverse shear force elimination device 15 are embedded in the grooves of the top cover 1 and are fixedly connected by the second top connecting shaft 3.

[0035] like Figure 4 As shown, the intermediate connecting mechanism 4 has six symmetrical grooves on both the upper and lower sides. The upper grooves are used for the first to sixth transverse shear force elimination devices 12-17, and the lower grooves are used for the seventh to twelfth transverse shear force elimination devices 18-23. The bottom ends of the first transverse shear force elimination device 12, the fifth transverse shear force elimination device 16, and the sixth transverse shear force elimination device 17 are embedded in the upper grooves and fixedly connected by the upper first intermediate connecting shaft 5; the bottom ends of the second transverse shear force elimination device 13, the third transverse shear force elimination device 14, and the fourth transverse shear force elimination device 15 are embedded in the upper grooves and fixedly connected by the upper second intermediate connecting shaft 6; the top ends of the seventh transverse shear force elimination device 18, the eighth transverse shear force elimination device 19, and the ninth transverse shear force elimination device 20 are embedded in the lower grooves and fixedly connected by the lower third intermediate connecting shaft 7; the top ends of the tenth transverse shear force elimination device 21, the eleventh transverse shear force elimination device 22, and the twelfth transverse shear force elimination device 23 are embedded in the lower grooves and fixedly connected by the lower fourth intermediate connecting shaft 8.

[0036] like Figure 5 As shown, the base 11 has six symmetrical grooves, each with a through hole. The bottom ends of the seventh transverse shear force eliminator 18, the eighth transverse shear force eliminator 19, and the ninth transverse shear force eliminator 20 are embedded in the grooves of the base 11 and fixedly connected by the first base connecting shaft 9; the bottom ends of the tenth transverse shear force eliminator 21, the eleventh transverse shear force eliminator 22, and the twelfth transverse shear force eliminator 23 are embedded in the grooves of the base 11 and fixedly connected by the second base connecting shaft 10.

[0037] Working principle: When the system is subjected to shear force, the rod-connecting mechanism 26 of the lateral shear force relief device transmits the lateral force to the hollow connecting mechanism 25 through the metal rod. The spring 24 is compressed or stretched, converting the lateral force into axial elastic force, thereby eliminating the direct effect of the lateral shear force on the top cover 1 and the base 11. The symmetrical distribution of the 12 devices ensures a balanced force transmission path and avoids structural eccentric loading.

[0038] Principle Explanation

[0039] This invention absorbs horizontal vibrations through the axial deformation of spring 24, combined with the transitional fit between the hollow connecting mechanism 25 and the rod connecting mechanism 26, and by vertically arranging the transverse shear force elimination device, achieving the effect of eliminating horizontal vibrations while transmitting axial force. The stiffness design and preload application of spring 24 ensure effective elimination of horizontal vibrations under rated load. The symmetrical distribution of the 12 devices forms a symmetrical force transmission network, keeping the system stable during multi-directional vibrations.
