摘要： The improved sliding bearing provides fitting of a cap into a sleeve with steadily fixation of adhesive, and prevention of the remained adhesive outside of the desired area. The sliding bearing comprises a sleeve, a shaft enclosed in said sleeve, and, a cap fitted into the sleeve, the sleeve having a shouldered hole with a first shoulder on which the cap is held, wherein the internal circumferential surface of the sleeve or the external circumferential surface of the cap includes a second shoulder circumferentially formed thereon. The second shoulder of the sleeve is of an outer diameter larger than the diameter of the cap, and an inner diameter approximately same as or slightly larger than the outer diameter of the cap, while the second shoulder of the cap is of an inner diameter smaller than that of the sleeve, and an outer diameter approximately same as or slightly smaller than the inner diameter of the sleeve.

摘要： A dynamic pressure bearing is provided in which leakage of liquid lubricant due to precession of a housing can be prevented from occurring. In the dynamic pressure bearing, the inner diameter of a tapered inner peripheral face 20 of the housing 1 which constitutes a capillary sealing portion 23 is gradually increased as moving from an opening 17 toward the inner area in the axial direction. When the housing 1 is rotated, therefore, a centrifugal force applied on liquid lubricant existing on the tapered inner peripheral face 20 acts in the direction along which the liquid lubricant is pushed toward the inner area, as indicated by an arrow 19. Consequently, the centrifugal force which is due to precession of the housing 1, and which pushes the liquid lubricant 15 toward the outside as indicated by an arrow 29 can be cancelled by the force acting in the direction toward the inner area, with the result that leakage of the liquid lubricant due to precession of the housing 1 can be prevented from occurring.
摘要翻译：提供动态压力轴承，其中可以防止由于壳体的进动而导致的液体润滑剂的泄漏。在动压轴承中，构成毛细管密封部23的壳体1的锥形内周面20的内径随着从开口17向轴向的内侧区域移动而逐渐增大。因此，当壳体1旋转时，施加在锥形内周面20上的液体润滑剂上的离心力沿箭头19所示向液体润滑剂被推向内侧的方向作用。因此，由于壳体1的进动引起的离心力，如箭头29所示将液体润滑剂15推向外部的离心力可以通过朝向内部区域的方向作用的力来抵消，结果是泄漏可以防止由于壳体1的进动引起的液体润滑剂的发生。

摘要： A dynamic pressure bearing has a large load-carrying capacity, and a ridge portion defined between adjacent grooves is prevented from damaging an opposite surface. The bearing includes an axial bearing surface having dynamic pressure generating grooves formed thereon by plastic working. The bearing has ridge portions defined between the adjacent dynamic pressure generating grooves. A top end of the ridge portion has rounded edge portions and a flat bearing surface defined between the edge portions. Since the edge portions of the top end are rounded, an opposite surface is prevented from being damaged. Further, the presence of the flat bearing surface defined between the edge portions results in increased load-carrying capacity.

摘要： First, an axial clearance is measured. Next, lubricating oil is filled between a sleeve and a shaft, and the shaft is disposed such that a flange is positioned above a shank. Further, in a state where the shaft rotates at a rated rotation speed (a predetermined rotation speed), an axial clearance b between the flange and a surface facing a receiving surface of the flange through a flange housing space in the sleeve is measured. Finally, a dynamic pressure bearing satisfying the condition 0.3≦b/a≦0.55 is judged as a dynamic pressure bearing not having leakage of lubricating oil and abnormal abrasion.

摘要： A dynamic pressure bearing which can eliminate an unbalanced existence of a lubricant fluid without increasing the diameter of a flange is compact in size and requires a lower rotation torque. The dynamic pressure bearing, axial through holes 21 and 22 of a flange 2 are formed so as to be adjacent to a smaller diameter portion 1B of a shaft 1, and to be opposed to an end face 1A-1 of a larger diameter portion 1A. Thus, the axial through holes 21 and 22 do not reduce the area for forming a bearing surface of the flange 2, so that the unbalanced existence of a lubricant fluid can be eliminated by the axial through holes 21 and 22 without degrading the thrust supporting ability. The diameter of the flange can be reduced, and a stable supporting ability can be attained, and a compact size and a low rotation torque can be realized.
摘要翻译：能够消除润滑剂流体的不平衡存在而不增加凸缘直径的动态压力轴承尺寸紧凑，并且需要较低的旋转扭矩。凸缘2的轴向通孔21和22的动压轴承形成为与轴1的较小直径部分1B相邻并且与较大直径部分1A的端面1A-1相对。因此，轴向通孔21和22不会减小用于形成凸缘2的支承表面的区域，从而通过轴向通孔21和22可以消除润滑剂流体的不平衡的存在，而不会降低推力支撑能力。能够减小凸缘的直径，能够获得稳定的支撑能力，能够实现紧凑的尺寸和低的转矩。

摘要： It is an object of the invention to provide a bearing device in which the bearing performance is not lowered even when the temperature is changed. In order to attain the object, the bearing device has a shaft and a sleeve. The shaft is made of stainless alloyed steel and has dynamic pressure generating grooves of a herringbone-like shape. The sleeve consists of the body made of a copper alloy, and an electroless nickel plated layer which covers the whole surface of the body. The electroless nickel plated layer has a coefficient of thermal expansion which is smaller than that of the body made of a copper alloy. The coefficient of thermal expansion of the shaft made of stainless alloyed steel is smaller than that of the body of the sleeve made of a copper alloy. When the temperature is raised, the electroless nickel plated layer suppresses the amount of thermal expansion of the body.

摘要： In left and right web plates (12) of a boom (11), first to fifth web materials (12A to 12E) are joined at edge portions in a front-rear direction along welding lines (13A to 13D). In an upper flange plate (14), a rear upper flange material (14A), a front upper flange material (14B), and a middle upper flange material (14C) are joined at edge portions in a front-rear direction along welding lines (15A, 15B). Ina lower flange plate (16), first to sixth lower flange materials (16A to 16F) are joined at edge portions in a front-rear direction along welding lines (17A to 17E). The welding lines (13A to 13D) of the left and right web plates (12) are disposed in positions that are different from those of the welding lines (15A, 15B) of the upper flange plate (14) and the welding lines (17A to 17E) of the lower flange plate (16) in a front-rear direction. This makes it possible to reduce the entire weight and thereby achieve reduction in weight while ensuring bending strength, torsional strength, and the like of the boom (11).

摘要： Turbines and compressors, which constitute superchargers, are disposed in series on an exhaust gas passage and an air intake passage, respectively. The supercharger is equipped with a supercharger rotation sensor, which transmits a detection signal obtained according to the rotation of the compressor to a control device, a bypass passage, which bypasses exhaust gas from the upstream side to the downstream side of the turbine, and a bypass valve, which regulates the flow rate of exhaust gas flowing through the bypass passage. Control device regulates the rotational speed of the compressors in a high-efficiency range by producing a control signal based on the detection signal from the supercharger rotation sensor, and sending the control signal to the bypass valve.
