Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbing equipment, in particular to a silent elastic colloid shock absorbing spring. Background Art

[0002] Mechanical equipment will generate vibration during operation. Long-term vibration will loosen the bolts and other parts on the machine. Once the bolts fall off, the rotating machine cannot remain stable, which will cause damage to the machine or transmission mechanism, thereby causing losses to the company's production and economy. Shock absorber is a common shock absorbing device that uses the elasticity of the spring to reduce the vibration generated by mechanical equipment. The spring of the existing shock absorber is directly connected to the connecting studs at both ends. When the spring is squeezed, it is easy to make annoying noise, affecting the working environment of the workshop, and causing excessive wear of the spring. Utility Model Content

[0005] Preferably, the elastic body is fixed on the supporting shaft through a limit block, and the sleeve is provided with a structure to prevent the elastic body from moving relative to the sleeve.

[0006] Preferably, the cross-sections of the sleeve and the support shaft are both rectangular, and the sleeve and the support shaft are arranged at a 45-degree angle, thereby forming four right-angled triangular intervals in the sleeve, and each interval is provided with an elastomer, which is respectively fitted with two right-angled sides of the triangular interval to prevent it from moving relative to the sleeve.

[0007] Preferably, the cross-section of the elastic body is a right triangle, extending along the length direction of the sleeve, and the two right-angled sides of the triangle are respectively in contact with the inner wall of the sleeve.

[0008] Preferably, the elastic module, the support seat and the support arm are connected by bolts.

[0009] Preferably, the elastic body is made of rubber material.

[0010] Preferably, the bottom wall of the support base is provided with bolt holes for connecting the support base with other components.

[0011] In summary, the utility model has the following beneficial effects:

[0012] The silent elastic colloid shock-absorbing spring provided by the utility model includes three main components, namely: two upper and lower support seats, an elastic module and a support arm, and the three components together form a structure that is approximately in the shape of a "Z"; wherein, the elastic module includes a sleeve wrapped on the outside, a support shaft is arranged in the sleeve, and each gap between the sleeve and the support shaft is filled with an elastomer; when the machine applies downward pressure to the device, the pressure is transmitted to the support shaft through the support seat, and the support shaft squeezes the elastomer to deform it, thereby playing a shock-absorbing role, and when the pressure is removed, the elastomer rebounds and the device returns to its initial position; because the gap between the support shaft and the sleeve, which is the main force-bearing component, is filled with an elastomer made of rubber material, and the elastomer made of rubber material has the effects of high elasticity, high strength, durability and silence, thus avoiding direct contact between metals and effectively reducing noise.

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] The positions involved in this specification are based on the positions of the silent elastic colloid shock-absorbing spring of the utility model during normal operation, and do not limit the positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0022] like Figures 1 to 6 As shown together, a silent elastic colloid shock-absorbing spring includes two support seats 1 symmetrically arranged at the upper and lower ends of the shock-absorbing spring, the support seat 1 includes a bottom wall and side walls arranged on the front and rear sides of the bottom wall, and the bottom wall of the support seat 1 is provided with bolt holes 5 for connecting the support seat 1 with other components; an elastic module is connected between the front and rear side walls of the support seat 1, and the two groups of elastic modules on the upper and lower support seats 1 are connected by a support arm 2, and two support arms 2 are provided, which are respectively connected to the front and rear sides of the elastic module.

[0023] The elastic module includes two elastic modules 3 fixed together, wherein the two ends of the support shaft 304 of one elastic module 3 extend out and are connected to the support seat 1, and the two ends of the support shaft 304 of the other elastic module 3 extend out and are connected to the support arm 2; the elastic module 3 includes a sleeve 303 wrapped on the outside, a support shaft 304 is arranged in the sleeve 303, an elastomer 301 is arranged in the gap between the sleeve 303 and the support shaft 304, the length of the sleeve 303 is smaller than the support shaft 304, the two ends of the support shaft 304 extend out and are respectively provided with two groups of threaded blind holes, and the elastic module 3 is respectively connected to the support seat 1 and the support arm 2 by bolts 4; in this scheme, the elastic module 3 and the support seat 1 and the support arm 2 are connected by two groups of bolts 4 to ensure their stability.

[0024] The elastomer 301 is fixed on the support shaft 304 by a limit block 302, and a structure is provided on the sleeve 303 to prevent the elastomer 301 from moving relative to it; preferably, in this scheme, the cross-sections of the sleeve 303 and the support shaft 304 are both rectangular, and the sleeve 303 and the support shaft 304 are set at a 45-degree angle in the direction of the cross-section, so that four right-angled triangular intervals are formed in the sleeve 303, and an elastomer 301 is provided in each interval, and the elastomer 301 is respectively fitted with two right-angled sides of the triangular interval, so that it cannot move relative to the sleeve 303; in other schemes, the sleeve 303 and the support shaft 304 can also be circular or other shapes.

[0025] Preferably, in this embodiment, the cross-section of the elastomer 301 is a right triangle, extending along the length direction of the sleeve 303 and having the same length as the sleeve 303; the two right-angled sides of the triangle are respectively fitted with the inner wall of the sleeve 303, so that it cannot move relative to the sleeve 303; the elastomer 301 is made of rubber material, which has the effects of high elasticity, high strength, durability and silence.

[0026] When in use, the bolt holes 5 on the bottom wall of the support base 1 are used to bolt the device to a machine that requires shock absorption. When the machine applies downward pressure to the device, the pressure is transmitted to the support shaft 304 through the support base 1. The support shaft 304 squeezes the elastomer 301, causing it to deform and play a shock-absorbing role. When the pressure is removed, the elastomer 301 rebounds and the device returns to its initial position. Because the gap between the main force-bearing component, the support shaft 304, and the sleeve 303 is filled with the elastomer 301 made of rubber material, direct contact between metals is avoided, effectively reducing noise.

Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
