Description

Technical Field

[0001] This utility model relates to the field of vibration isolator technology, specifically to a three-dimensional vibration isolator without angular displacement. Background Technology

[0002] In the fields of mechanical engineering, transportation, and industrial equipment, vibration isolators, as core components for buffering vibration and shock, directly affect the stability, lifespan, and safety of equipment operation. The application of triaxial vibration isolators provides the same stiffness in multiple directions to suppress vibration transmission, achieving stiffness balance in all directions, thereby improving equipment stability and shock resistance.

[0003] However, existing triaxial vibration isolators mainly rely on axial elastic deformation to absorb energy, which is insufficient for buffering lateral vibration or torsional impact, and can easily lead to equipment sway, affecting the vibration reduction effect of the triaxial vibration isolator. Therefore, a triaxial vibration isolator without angular displacement is provided. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional vibration isolator without angular displacement, comprising:

[0006] Circular base;

[0007] A tower-shaped spring is vertically fixed to the upper surface of the annular base;

[0008] A rubber shock-absorbing core is wrapped around the outer side of the annular base and the tower-shaped spring to form an integrated wrapping structure;

[0009] The connecting seat assembly is longitudinally installed in the central hole of the rubber shock-absorbing core.

[0010] Preferably, the connecting seat assembly includes a columnar connecting seat, wherein a radially extending annular connecting disk is provided in the middle of the side wall of the columnar connecting seat, and the lower surface of the annular connecting disk is connected to the top of the tower-shaped spring.

[0011] Preferably, the upper surface of the annular base and the lower surface of the annular connecting plate are respectively provided with concentric positioning grooves, and the two ends of the tower-shaped spring are embedded in the positioning grooves by interference fit.

[0012] Preferably, the top of the connecting seat assembly is provided with a flange, the surface of the flange is provided with anti-slip texture, and the diameter of the flange is larger than the diameter of the central hole of the rubber shock-absorbing core.

[0013] Preferably, the rubber shock-absorbing core is made of natural rubber.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model provides a three-dimensional vibration isolator without angular displacement. Through the integrated wrapping of the vertical fixing structure of the tower-shaped spring and the rubber damping core, it achieves multi-dimensional energy dissipation in the axial, lateral, and torsional directions. The gradient deformation characteristics of the tower-shaped spring, combined with the shear deformation capacity of the rubber body, create a synergistic effect between axial compressive deformation and lateral shear deformation. This effectively solves the problem of equipment sway caused by insufficient buffering capacity of traditional vibration isolators for lateral vibration or torsional impact, ensuring the vibration reduction effect of the three-dimensional vibration isolator.

[0018] 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.

[0019] Please see Figure 1-2This utility model provides a technical solution: a three-dimensional vibration isolator without angular displacement, including an annular base 1; a tower-shaped spring 2 vertically fixed to the upper surface of the annular base 1; a rubber damping core 3 covering the outer side of the annular base 1 and the tower-shaped spring 2, forming an integrated covering structure; the rubber damping core 3 adopts a matching design of natural rubber material and tower-shaped spring 2, which effectively prevents the rubber damping core 3 from delamination and cracking during use, improves the fatigue resistance of the three-dimensional vibration isolator, and increases the service life of the overall structure; the connecting seat assembly 4 is longitudinally installed in the central hole of the rubber damping core 3; through the vertical fixing structure of the tower-shaped spring 2 and the integrated covering of the rubber damping core 3, multi-dimensional energy dissipation in the axial, lateral and torsional directions is realized; the gradient deformation characteristics of the tower-shaped spring 2, combined with the shear deformation capacity of the rubber body, make the axial compression deformation and lateral shear deformation form a synergistic effect, effectively solving the problem of equipment sway caused by insufficient buffering capacity of traditional vibration isolators for lateral vibration or torsional impact, and ensuring the vibration reduction effect of the three-dimensional vibration isolator.

[0020] Specifically, the connecting seat assembly 4 includes a columnar connecting seat 41, with a radially extending annular connecting disc 42 in the middle of the side wall of the columnar connecting seat 41. The annular connecting disc 42 can evenly distribute the force to the tower spring 2, avoiding local stress exceeding the limit. The lower surface of the annular connecting disc 42 is connected to the top of the tower spring 2. The top of the connecting seat assembly 4 is provided with a flange 43, and the surface of the flange 43 is provided with anti-slip texture. By setting the anti-slip texture, the damping between the flange and the connecting parts is increased, which effectively improves the stability of the connection with the connecting parts. The diameter of the flange 43 is larger than the diameter of the central hole of the rubber shock-absorbing core 3.

[0021] Specifically, the upper surface of the annular base 1 and the lower surface of the annular connecting plate 42 are respectively provided with concentric positioning grooves 5. The two ends of the tower spring 2 are embedded in the positioning grooves 5 by interference fit. Through the mechanical constraint of the concentric positioning grooves 5, the axis of the tower spring 2 coincides with the center line of the vibration isolator, ensuring the symmetry of the three-dimensional stiffness. Under the action of lateral load, the interference fit can suppress the radial slippage of the end of the tower spring 2 and avoid shear tearing of the rubber damping core 3 due to the misalignment of the metal parts.

[0022] Working principle: When this utility model is working, the vertical fixing structure of the tower spring 2 and the integrated wrapping of the rubber shock-absorbing core 3 realize multi-dimensional energy dissipation in the axial, lateral and torsional directions; the gradient deformation characteristics of the tower spring 2, combined with the shear deformation capability of the rubber body, make the axial compression deformation and lateral shear deformation form a synergistic effect.
