In the technical scheme, because the material hardness of the anti-shearing structure 12 is higher than that of the vibration isolation pad body 1, when the vibration isolation pad is installed in the installation hole 100 of the motor, the shearing of the hole wall of the installation hole of the motor to the matching groove of the vibration isolation pad can be effectively resisted, the service life of the vibration isolation pad is effectively prolonged, and the vibration isolation pad is prevented from losing efficacy.

The formation of the shear-resistant structure 12 may be various, for example, the shear-resistant structure 12 is implemented by plating, that is, the shear-resistant structure 12 may include a shear-resistant material layer; alternatively, the anti-shearing structure 12 comprises an anti-shearing shell, that is, the anti-shearing structure 12 is formed by a shell with a material hardness higher than that of the vibration isolator body 1, which can simplify the production and manufacturing process of the vibration isolator. The shear resistant material may be selected from reinforced polypropylene, steel, aluminum, or other relatively rigid materials, for example.

As a specific embodiment of the shear resistant housing, it is preferable that the shear resistant housing includes a first cylinder 121, both ends of the first cylinder 121 respectively have a first radial wall 122 and a second radial wall 123 extending outward in a radial direction of the first cylinder 121, and an insertion space of the motor mounting hole is formed between the first radial wall 122 and the second radial wall 123 parallel to each other and the first cylinder 121, as shown in fig. 5, which shows a motor 101 having a U-shaped mounting hole 100, in this case, the vibration isolating pad adopting the technology of the present invention is assembled toward the mounting hole 100 in a manner shown by an arrow in the figure, and a hole wall of the mounting hole 100 directly contacts with the shear resistant housing of the present application to form protection for the vibration isolating pad body 1, so as to effectively prolong a service life of the vibration isolating pad.

Preferably, one side of the anti-shearing shell facing the vibration isolator body 1 is provided with a plurality of first protruding structures, the first protruding structures are embedded in the vibration isolator body 1, and due to the difference in material selection between the anti-shearing shell and the vibration isolator body 1, the anti-shearing shell and the vibration isolator body are easily separated at a joint surface, and especially after the vibration isolator is repeatedly stressed for a long time, the anti-shearing shell and the vibration isolator body 1 are more easily separated from each other. Further, the first protruding structure has a recessed structure, and the recessed structure can accommodate a part of the vibration isolator body 1, that is, a part of the vibration isolator body 1 is also embedded in the first protruding structure at this time, so that the reliability of the combination between the anti-shearing housing and the vibration isolator body 1 can be further improved.

Furthermore, the vibration isolation pad body 1 is provided with a connecting piece passing hole 13, the inner peripheral wall of the connecting piece passing hole 13 is provided with an anti-abrasion structure 14, the material hardness of the anti-abrasion structure 14 is higher than that of the vibration isolation pad body 1, and in the selection of specific materials, the material hardness is preferably the same as that of the anti-shearing structure 12, but can be different. Specifically, the anti-wear structure 14 includes a layer of anti-wear material; alternatively, the wear-resistant structure 14 comprises a wear-resistant housing, so as to effectively resist the wear of the vibration isolator main body 1 caused by connecting members, such as the connecting bolts 103.

As a specific embodiment of the abrasion-resistant housing, preferably, the abrasion-resistant housing includes a second cylinder 141, and one end of the second cylinder 141 has a third radial wall 142 extending radially outward along the second cylinder 141. At this moment, the anti-shearing shell and the anti-abrasion shell are respectively arranged on the outer side and the inner side of the vibration isolation pad body 1, and can effectively resist shearing and/or abrasion of the vibration isolation pad body 1 caused by the hole wall of the mounting hole 100 and the connecting bolt 103.
