摘要： There is disclosed a polygon mirror motor in which an annular projection is formed on an upper surface of a rotor support member supporting a polygon mirror, and the annular projection supports a part of a lower surface of the polygon mirror. Radial bearings supporting a shaft of the motor have a plurality of oil grooves extending over about a half of the dimension of the radial bearing in a thrust direction. A magnetic fluid is filled in a space defined by the shaft, a support tube of a bearing support member and the radial bearings.

摘要： A thrust bearing including a ring-like form plate body, and a plurality of rib members provided on the ring-like form plate body of the thrust bearing. Such a plurality of rib members may be provided on a thrust runner. The rib members cause a difference in load deformation amount in a circumferential direction according to thrust load and generate a wedge-shaped form clearance between a sliding face of the thrust bearing and a sliding face of the thrust runner. Since the wedge-shaped form clearance is formed by utilizing the load deformation, even when the thrust load becomes large, the wedge-shaped form clearance does not become narrow. The occurrence of dynamic pressure by the wedge effect and the formation of a water film can be assured, and the temperature increase between the sliding face of the thrust runner and the sliding face of the thrust bearing can be restrained.

摘要翻译： 推力轴承，其包括环状的板状体，以及设置在推力轴承的环状的板状体上的多个肋部件。 这样的多个肋构件可以设置在推力滑轮上。 肋构件根据推力负载引起圆周方向的载荷变形量的差异，并且在推力轴承的滑动面和推力滑轮的滑动面之间产生楔形的间隙。 由于通过利用负载变形来形成楔形的间隙，所以即使推力负荷变大，楔形间隙也不会变窄。 可以确保通过楔形效应产生的动态压力和水膜的形成，并且可以抑制推力滑块的滑动面与推力轴承的滑动面之间的温度升高。

摘要： A rotary anode X-ray tube accommodated in a housing together with oil has a journal box fixed and inwardly extending inside the tube, an anode target fixed to a rotor supported by the journal box and a cathode member opposing the anode target and fixed at an end portion inside the tube opposing the journal box. The fixing portion between the rotary anode X-ray tube and the journal box is supported by a resilient support member on the housing and vibration damping means is disposed on the support member. The vibration damping means includes a moving member fixed at its center and a fixed member fixed to the housing so as to encompass the moving member with a predetermined gap, and oil is fully charged in the gap. Vibration of the rotation system is transmitted to the moving member and the operation of this member damps the vibration by means of the squeeze action of the oil.
