摘要： The disclosure relates to a centrifuge with a balancing mechanism and method of balancing such a centrifuge. The centrifuge includes a vertical shaft driven in rotation by a motor, and a mechanism for balancing the parts integral with said vertical shaft. The mechanism includes a plate integral with the vertical shaft, at least one compensating mass freely displacing on the plate, the mass being designed to limit the imbalance of parts integral with the vertical shaft, and a mechanism for blocking the compensating mass, the blocking mechanism being designed to immobilize the compensating mass on the plate when the rotation speed exceeds a determined value.

摘要： A drive arrangement for a rotational body device comprising a shaft which is held rotatably with respect to a rotational axis, a first bearing module and a second bearing module, each with at least one elastic support element for supporting the shaft, an electric motor, an electrically actuable stabilisation device, and a housing. At least the first bearing module provides a mass body which is held in a non-rotatable fashion with respect to rotational axis by means of the at least one elastic support element. The shaft is supported in a rotatable fashion on the mass body by a bearing of the first bearing module.

摘要： A support structure for a rotation driving system having a ball balancer includes: a motor having a rotational shaft coupled to a rotational shaft of a rotor; the ball balancer provided on the rotor to reduce oscillating motion of the rotor; and a support part for coupling the motor to a housing, wherein the motor is coupled to the housing via an elastic member on a line in one direction (x-axis) perpendicular to an axial direction (z-axis) of the rotational shaft of the motor, and the motor is allowed to swing about the x-axis due to elastic deformation of the elastic member.

摘要： A centrifuge rotor assembly includes a chamber assembly, a bearing support, and a counterweight that is substantially diametrically opposed to the bearing support with respect to the chamber assembly. The chamber assembly receives a processing chamber of a fluid circuit, while the bearing support receives a portion of an umbilicus that is fluidly connected to the processing chamber. The bearing support and counterweight are rotated about a central axis of the chamber assembly by an electric drive of the centrifuge rotor assembly, with the bearing support and counterweight remaining substantially diametrically opposed to each other with respect to the chamber assembly while being rotated about the central axis. The electric drive may rotate the bearing support and counterweight at a plurality of different speeds, with the counterweight automatically moving with respect to the bearing support between radially innermost and radially outermost positions to balance the centrifuge rotor assembly.

摘要： A method, system, and apparatus for aligning the index angle of a polar coordinate system device, such as the rotor of a centrifuge, with the vertical axis of a Cartesian coordinate system device, such as a robotic end-effector. The apparatus includes a first registration device, that is removably attached to the gripping means of the end-effector and a second registration device, that is removably insertable into a pivoting platform, such as a bucket to a centrifuge rotor. As the first registration device is lowered into the second registration device, the fixed orientation of the notches of the second registration device and the rigid nature of the first registration device cause a linear ball slide to displace and the bucket to rotate until the primary axis of the linear ball slide is in compliance with the cross pin axis of the first registration device.
