专利汇可以提供Shock absorber for rotary member专利检索,专利查询,专利分析的服务。并且PURPOSE:To provide a shock absorber for a rotary member which is simple in its construction and easy to work and assemble and has improved damping features by utilizing a shearing action of an oil film which is caused to appear in a gap between a movable disc and a stationary plate. CONSTITUTION:During a high speed rotation of a rotary member, vibrations of a bearing 12 therefor are increased when the critical speed is passed or if a whirling force is caused to occur. Oil films of lubricating oil are caused to appear in and fill gaps 18 and 19 which are formed respectively between the bottom 3 of an oil tank 1 and a movable disc 9 and between the movable disc 9 and an annular stationary plate 15. The damping force for preventing such vibrations of the bearing 12 arises from the viscosity of the oil films when they are subjected to shearing deformations by such vibrations. Magnets 7 are embedded in the bottom 3 of the oil tank 1 so as to attract magnets 8 embedded in the movable disc 9 thereby preventing the bearing from being rotated and providing the bearing with a centripetal force.,下面是Shock absorber for rotary member专利的具体信息内容。
