摘要： The invention relates to a device for receiving a workpiece in a bearing device for rotatably mounting the workpiece about a bearing axis (L) associated with a workpiece bearing surface. The device comprises a bearing pedestal (14) including a bearing element (1) which has two concavely cylindrical bearing surfaces (5, 6) that lie next to one another in the same bearing plane and symmetrically to a plane of symmetry containing the bearing axis (L), the cylinder radii of the cylindrical bearing surfaces being greater than the radius of the workpiece bearing surface for which the bearing device is intended, wherein the cylinder axes of the two bearing surfaces (5, 6) are parallel to the bearing axis (L) and have a distance between each other.

摘要： A method is described for calibrating a balancing machine, in which a rotor (1) to be corrected is rotatably mounted in bearings (2) and a correction run k is performed, wherein at least one measuring sensor (3) determines an initial vibration of the rotor (1) prior to an imbalance correction and transmits this vibration to an evaluation device (4), which stores the measured value as vibration vector {right arrow over (s)}0. After an imbalance on the rotor (1) is corrected, a residual vibration of the rotor (1) is measured by measuring sensor (3), transmitted to the evaluation unit (4) and stored as vibration vector {right arrow over (s)}1. The difference δ{right arrow over (s)}={right arrow over (s)}1−{right arrow over (s)}0 formed from the measurement data and the corrected imbalance is stored for compensation run k as δ{right arrow over (s)}k and {right arrow over (u)}k by the evaluation unit (4). To undertake a calibration of the machine, one can either determine a process calibration matrix K by solving the equation system S=UKT using the collected measurement data or one can select an already available process calibration matrix using the initial vibration {right arrow over (s)}0 and/or imbalance vector {right arrow over (u)} and store it as a calibration matrix in the evaluation unit (4) and use it to calculate an unknown imbalance vector of a rotor (1).

摘要： In a method for determining an equivalent modal unbalance for the first bending characteristic form of a shaft-elastic rotor, which unbalance is to be compensated for, a rotor model is created describing the geometric shape and material properties of the shaft-elastic rotor. The magnitude of compliance of the rotor model is calculated at a measurement point and at the center of gravity of the rotor at an assumed speed. The shaft-elastic rotor is received in a rotatable bearing and accelerated to the assumed speed which is below its first critical speed. Subsequently, the magnitude of outward deflection at the measurement point of the shaft-elastic rotor rotating at the assumed speed can be measured. The equivalent modal unbalance for the first bending characteristic form of the shaft-elastic rotor, which unbalance is to be compensated for, can be calculated from the magnitudes of the calculated compliance and the measured outward deflection.

摘要： The invention relates to a device for attaching a balancing weight (2) to a mounting surface (17) on an inner side (3) of a rim dish of a wheel rim (4) and provides for a mounting head (1) to be dimensioned in such a way that it fits into the rim dish. The mounting head (1) includes a support element (5), which is radially displaceable relative to the wheel rim (4) and on which a feeler element (6) is axially movably arranged, the feeler element (6) having a convex contact surface (14) and a receptacle (12) for at least one balancing weight (2), said receptacle being oriented towards the inner side (3). The mounting head (1) is configured in such a way that the contact surface (14) may be brought into contact with a boundary surface (18) of the inner side (3), and may be displaced along said boundary surface until the balancing weight (2) comes radially into contact with the mounting surface (17).

摘要： Disclosed is a device for attaching corrective weights to a cylindrical outer surface of a rotor by means of electric resistance pressure welding, including an electrode (1) having a contact surface (20) for application against the rotor and comprising a supporting body (2) and a swinging body (6) having oppositely facing, congruent, spherical bearing surfaces (5, 8) suitable for abutting engagement with each other. The swinging body (6) is movably secured to the supporting body (2) such as to be able to perform limited swinging movements to all sides. A spring (14) arranged between the supporting body (2) and the swinging body (6) enables a gap to be produced between the spherical bearing surfaces (5, 8), whereby the contact surface (20) is in a position to align itself relative to the opposite surface of the rotor prior to pressure application by the welding force.

摘要： Disclosed is a clamping device of a balancing machine for coaxially clamping a toolholder on a spindle rotary about an axis of rotation (3), in which the coupling shank (8) is supported in the receiving socket only on discrete supports (11-15) which are spaced from each other circumferentially and lie in three relatively spaced engagement planes (E1, E2, E3) intersecting the axis of rotation (3). Four rigid discrete supports (11-14) are arranged in pairs in the first (E1) and the second (E2) engagement plane and combine to form a rigid support in a first radial direction. Formed in the third engagement plane (E3) lying between the first and the second engagement plane is a fifth discrete support (15) which effects a supporting function in a second radial direction opposite the first radial direction.

摘要： To correct an unbalance of rotors, a method and a device are proposed by means of which a corrective weight (15) is adapted to be welded to a rotor (2) by means of an electric welding device (14). The device comprises a robot (20) with a jointed arm (21) mounting the electric welding device (14). Arranged within reach of the jointed arm (21) is an unbalance measuring station (1) for measuring the amount of unbalance of the rotor (2) with an electronic computer which computes a corrective weight (15) to be attached to the rotor (2) for unbalance correction and transmits control data to a control device (23) of the robot (20). Under robot control, the welding device (14) picks the computed corrective weight (15) from a magazine (27) arranged within reach of the jointed arm (21) and welds it to the rotor (2) in the unbalance measuring station (1). During the welding operation the rotor (2) takes support on a first supporting device (11) and the welding device (14) on a second supporting device (12).
