The invention relates to the technical field of new energy electric drive assembly NVH, and discloses a bearing vibration isolator with an adjustable vibration isolation rate, which comprises a base ring, a plurality of blades are arranged on the outer surface of the base ring, the blades are spirally distributed by taking the base ring as the center, triangular filling rubber is arranged at the joints of the base ring and the blades, a variable-diameter compression ring is arranged on the periphery of the base ring, and the variable-diameter compression ring is arranged on the periphery of the base ring. The blades abut against the inner wall of the compression ring. The invention further discloses a mounting structure and an adjusting method of the bearing vibration isolator with the adjustable vibration isolation rate. According to the bearing vibration isolator with the adjustable vibration isolation rate as well as the mounting structure and the adjusting method of the bearing vibration isolator, vibration transmitted out through the bearing is reduced by isolating vibration at the bearing near an excitation source, so that the high quietness requirement of an electric drive assembly is met.

    本发明涉及新能源电驱动总成NVH技术领域,公开了一种隔振率可调的轴承隔振器,包括基圈,基圈的外表面设有若干个叶片,叶片以基圈为中心呈螺旋状分布,基圈与叶片的连接处均设有三角填充橡胶,基圈的外围设有可变径的压缩圈,叶片抵住压缩圈的内壁。本发明还公开了一种隔振率可调的轴承隔振器的安装结构和调节方法。本发明隔振率可调的轴承隔振器及其安装结构和调节方法,通过在激励源附近的轴承处隔振,来降低通过轴承传递出去的振动,从而实现电驱总成高静谧性要求。
