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 random orbit sander includes a housing and a motor enclosed within the housing. The motor includes a motor shaft that is rotatable about a first axis. An eccentric carrier coupled to the motor shaft includes a circular internal bore that defines a second axis that is offset from the motor shaft. A bearing is received within the circular internal bore of the eccentric carrier. A sanding pad is supported by the bearing and is rotatable about the first axis in an eccentrically orbiting manner. The motor shaft and the eccentric carrier are integrally formed as a single piece.

摘要： The present disclosure relates to a grinding disk of a ground grinding machine driven by a motor, including a chassis, wherein a working surface of the chassis is a separate flat disk, fixed devices are arranged on a lower surface of the chassis, and grinding blocks are fixedly installed through the fixed devices. Compared with the prior art, the present disclosure has the following advantages: the size of the grinding working surface of the separate grinding disk may be set freely by changing the arrangement mode of the grinding blocks; so as to reduce the starting torque and achieve the buffer effect; and mounting grooves may adopt the circumferential alternate arrangement or the radial alternate arrangement, so that the installed grinding blocks may compensate for each other, and the uniform and complete grinding is ensured while reducing the quantity of the grinding blocks.
