Resilient member with deformed element and method of forming same

Abstract

An elastic component and a forming method thereof, the elastic component is used for isolating vibration and / or sound transmission. The elastic member (20) includes a first part (24) having a suitable profile (26), a second part (28) made of deformable material (such as thermoplastic material), and elastic part (32) (such as rubber). During the molding process, the second part (28) is deformed so that its shape and size are consistent with the surface (25) of the first part (24). In a preferred embodiment, the second part (28) is plastically deformed and conforms to the contour (26) of the first part (24), thereby creating a mechanical interlock. This article introduces the rotation and translation interlocking of the component and the method of forming this interlocking.

Description

Technical field [0001] The invention relates to the field of equipment containing elastic materials, such as elastic bearings, frames, shock absorbers, rod end structures, and the like. More particularly, the present invention relates to an improved elastic member that provides isolation of vibration transmission or smooth movement. Background of the invention [0002] Elastic rod end structures, that is, rod end structures containing elastic joints, are widely used in various connections, and are usually used with chains and cables. This typical rod end structure is shown in Figures 1 and 2, including a rigid outer sleeve 2, a plastic sleeve 3, elastic parts 4 and a rigid metal inner sleeve 5. The jacket 2 includes a main body part 6 which contains a transverse window 7 and a threaded part 8 extending radially from the main body part. The elastic part 4 is bonded to the outer surface of the inner sleeve 5 after being hardened. It includes a joint joint 9 which is slidably placed...

AI Technical Summary

Problems solved by technology

[0003] A particular problem with prior art rod end constructions is that it is desirable that the inner liner 5 be pressed into the plastic sleeve 3 with very little pressure so that the parts 3, 5 are united before assembly

Therefore, in some cases, the pressure between the liner 5 and the sleeve 3 is so great that it causes an abnormally large rotational resistance torque between them

In extreme cases, the plastic sleeve 3 can break

Conversely, in the case of certain error accumulations, there will be very little or no pressure fit between the parts, causing the inner liner 5 to fall out of the sleeve 3

What's more, when the fit is very loose, it will cause abnormal deflection between the connecting parts, resulting in violent impact during use
