摘要： A power tool includes a motor housing extending along a first axis, a motor positioned in the motor housing, a handle extending along a second axis perpendicular to the first axis, and a vibration damping assembly positioned between the motor housing and the handle. The vibration damping assembly includes a first coupling portion defined by the motor housing, a second coupling portion defined by the handle, and an elastomeric damper captured between the first coupling portion and the second coupling portion. The first coupling portion includes a first mating surface facing toward the handle, and the second coupling portion includes a second mating surface facing toward the motor housing and positioned opposite the first mating surface. The damper includes a mating surface portion that extends outward in a direction transverse to the second axis, and the mating surface portion is positioned between the first and second mating surfaces.

摘要： A power tool includes a motor housing, a motor, a handle coupled to the housing, and a vibration damping assembly. The motor is positioned in the motor housing and configured to rotatably drive an output shaft. The vibration damping assembly is positioned between the motor housing and the handle. The vibration damping assembly includes a first coupling portion defined by the motor housing, a second coupling portion defined by the handle, and an elastomeric damper captured between the first coupling portion and the second coupling portion. The first coupling portion includes a boss having a flange and a first groove. The second coupling portion defines an opening and includes first and second ribs extending into the opening and spaced apart along a longitudinal axis of the handle. The first and second ribs define a second groove therebetween. The damper occupies the first and second grooves.
