    摘要: A damping apparatus includes a contact roller provided to be rotatable about a rotation axis, a first support body by which the contact roller is rotatably supported, a second support body holding the first support body so that the rotation axis of the contact roller is parallel to an axis of a spindle, a drive mechanism driving the second support body to bring the contact roller into contact with a workpiece held by the spindle and to separate the contact roller from the workpiece, and a base supporting the second support body and the drive mechanism. The first support body is held by the second support body via an elastic rubber body.

    摘要: A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.

    摘要: Provided is a machine tool which is equipped with a floating mechanism, and the whole of which can be miniaturized and lightened, the floating mechanism being equipped with carriers of loads generated in both radial and thrust directions, resulting in deformation of the floating mechanism being reduced. The floating section (4) of the machine tool is provided with a hollow circular-plate-shaped inner ring (9) comprising an outer peripheral surface section (9a), an upper surface section (9b), and a bottom surface section (9c); and an outer ring (8) comprising an inner peripheral section (8a) and an inner ring receiving section (8b). The outer ring (8) is fixed to a robot arm. The inner ring (9) is fixed to a tool driving section. The outer peripheral surface of the inner ring (9) is formed by a spherical surface which is equidistant from the center point (14) of a hollow circular plate.

    摘要: A main spindle unit includes: a damper bearing that restricts vibrations of a main spindle by being supplied with a fluid; a fluid supply device that supplies the fluid to the damper bearing, and that is able to adjust a flow rate of the fluid; a vibration detection sensor that detects a vibration of the main spindle; and a controller that adjusts the flow rate of the fluid supplied from the fluid supply device, based on the magnitude of the vibration detected by the vibration detection sensor.
