Motor vibration damper

The utility model discloses a motor vibration damper, including casing, installing support, damping rings and bush, the installing support is installed on the casing, is equipped with the mounting hole on the installing support, and damping rings is nested in the mounting hole, the last through -hole that is equipped with of damping rings, and in the bush embedding through -hole, its characterized in that: the outer wall of bush sets up a plurality of recess towards outer salient a plurality of fixture block on damping rings's the internal face, the number of fixture block and recess equals that the fixture block is embedded into damping rings's recess, prevents damping rings and bush relative slip, solve prior art in the bush fastening technical problem that the shock attenuation effect is not good comes off easily on damping rings. 本实用新型公开了种电机减振装置，包括机壳、安装支架、减震圈和衬套，安装支架安装在机壳上，安装支架上设有安装孔，减震圈嵌套在安装孔里，减震圈上设有通孔，衬套嵌入通孔里，其特征在于：衬套的外壁面向外凸出若干个卡块，减震圈的内壁面上设置若干个凹槽，卡块与凹槽的个数相等，卡块嵌入到减震圈的凹槽，防止减震圈与衬套相对滑动，解决现有技术中衬套紧固在减震圈上容易脱落，
