Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a rubber shock absorber for reducing vibration and trembling. Background Art

[0002] As an important type of shock-absorbing component, rubber shock absorbers have been widely used in various types of machinery, automobiles, locomotives, water transportation vehicles, airplanes and other aircraft.

[0003] Existing rubber vibration dampers absorb vibration shock waves solely through deformation of the rubber portion. However, the relatively simple structure of the rubber portion of the rubber vibration damper results in insufficient damping strength when the rubber portion deforms, thereby reducing the vibration and tremor reduction effectiveness of the rubber vibration damper. Therefore, a rubber vibration damper for vibration and tremor reduction is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the vibration reduction and anti-vibration effect of the rubber vibration absorber in the prior art is not good, and to propose a rubber vibration absorber for vibration reduction and anti-vibration.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A rubber shock absorber for reducing vibration and trembling comprises an upper fixing portion, a lower fixing portion and a rubber elastic portion, wherein the upper fixing portion and the lower fixing portion are respectively arranged at the top and bottom of the rubber elastic portion, and an axial through-hole is provided inside the upper fixing portion, the lower fixing portion and the rubber elastic portion; the outer side wall of the rubber elastic portion is provided with an outward arc-shaped protrusion, the inner side wall of the rubber elastic portion is fixedly provided with a rubber reinforcement portion, and the interior of the rubber reinforcement portion is provided with a plurality of evenly distributed elastic strips.

[0007] Preferably, the rubber reinforcement portion and the rubber elastic portion are fixedly bonded by glue, and both the rubber elastic portion and the rubber reinforcement portion are damping rubber portions.

[0008] Preferably, the elastic strip is a spring steel strip with an arc structure.

[0009] Preferably, an annular reinforcement strip is provided on the inner side wall of the rubber reinforcement portion near the curved portion.

[0010] Preferably, the upper fixing portion and the lower fixing portion both adopt a T-shaped structure, and both the upper fixing portion and the lower fixing portion adopt hard rubber parts.

[0011] Preferably, mounting holes are provided on both sides of the upper fixing portion and both sides of the lower fixing portion.

[0012] Compared with the prior art, the present invention provides a rubber vibration damper for reducing vibration and trembling, which has the following beneficial effects:

[0013] The rubber vibration damper for vibration reduction and tremor prevention has a rubber reinforcement part and an elastic strip arranged inside the rubber elastic part. When the rubber elastic part is deformed by an external force, the rubber reinforcement part and the elastic strip are also deformed. At this time, the rubber reinforcement part and the elastic strip can increase the strength of the damping deformation of the rubber elastic part and increase the elastic recovery ability of the rubber elastic part, thereby improving the vibration reduction and tremor prevention effect of the rubber vibration damper and having high practicality.

[0014] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model adds a rubber reinforcement part and an elastic strip inside the rubber elastic part, which can increase the damping strength of the rubber shock absorber, thereby improving the vibration reduction and anti-tremor effect, and improving practicality.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

The rubber reinforcement part 5 and the elastic strips 6 can increase the structural strength of the rubber elastic part 3 and increase the damping effect of the rubber elastic part 3 at the same time.

[0022] Reference Figure 2 An annular reinforcement strip 7 is provided on the inner side wall of the rubber reinforcement part 5 and near the curved part. The annular reinforcement strip 7 can reinforce the inner side of the rubber reinforcement part 5 to prevent the curved part of the rubber reinforcement part 5 from being subjected to a large extrusion deformation external force.

[0023] Reference Figure 1-2 The upper fixing part 1 and the lower fixing part 2 both adopt a T-shaped structure, and both the upper fixing part 1 and the lower fixing part 2 are made of hard rubber parts. Mounting holes 8 are opened on both sides of the upper fixing part 1 and both sides of the lower fixing part 2. The upper fixing part 1 and the lower fixing part 2 can be fixedly installed on the two components that generate vibration through the mounting holes 8.

[0024] When in use, first fix the upper fixing part 1 and the lower fixing part 2 on the two vibrating parts with bolts. When the upper and lower parts vibrate, the upper fixing part 1 and the lower fixing part 2 squeeze the rubber elastic part 3 relative to each other. When the rubber elastic part 3 is deformed by external force, the rubber reinforcement part 5 and the elastic strip 6 are also deformed. At this time, the rubber reinforcement part 5 and the elastic strip 6 can increase the strength of the damping deformation of the rubber elastic part 3, and increase the elastic recovery ability of the rubber elastic part 3, thereby improving the vibration reduction and anti-vibration effect of the rubber shock absorber, and having high practicality.
