Abstract
A dynamic pressure bearing device for use in a motor including a shaft and a frame. Two bearings interconnect the shaft and the frame of the motor. The two bearings contain a noncompressible fluid. A mechanism for minimizing axial vibrational movement of the shaft is part of the bearing device. In one arrangement, the mechanism is a device connected to the shaft, such that a narrow gap is defined between an end of the device and the frame to provide a flow resistance to the noncompressible fluid. The device connected to the shaft maintains a decreasing width to minimize a loss of torque in the motor.
