摘要： PROBLEM TO BE SOLVED: To effectively prevent fretting abrasion between a housing and a bearing metal over a long period. SOLUTION: The bearing metal 5 is mounted on an internal surface (an internal surface of the housing) of a first mounting hole 2a of a large end part 2 of a connecting rod. A hard film having hardness >=Hv1000 is formed on a surface having smaller surface roughness of the internal surface of the housing and the internal surface of the bearing metal 5. Wear is surely prevented on the surface covered with the hard film by the hard film having high hardness and difficult to wear over a long period. As for the hard film formed on the surface having smaller surface roughness, also the surface roughness of the hard film itself becomes small according to surface roughness of a surface to be formed and also mating attackability that the hard film itself has becomes small. Therefore, wear resistance in both of the surface covered with the hard film and a surface on a mating side having no hard film formed can be highly maintained over a long period.

摘要： PURPOSE:To prevent degradation in the abrasion resistance by setting to a particular value the ratio of the width to the depth of a circumferential groove formed in the inner circumferential surface of the slide bearing. CONSTITUTION:A kelmet layer 4 having a prescribed thickness is formed on a main body 3 of a crankshaft bearing 1 of the internal combustion engine, and grooves 2a each having a circular-arc shaped cross section are formed. The ratio of the width B to the depth H of this groove 2a is set to 40 or more, for example, 43.5 to 100. A nickel plating layer 5 is formed on the upper surface of the kelmet layer 4 and a lead alloy plating layer 6 is formed on the upper surface of the plating layer 5. As a result, grooves 2 each having a resemblance to the groove 2a are formed on the upper surface of the lead alloy plating layer 6. This groove 2 is spirally formed in the circumferential direction so that it may define an angle of 1 deg. with respect to the rotational direction R of the crankshaft. This enables suppressing the occurrence of wear at the crest portions of the groove 2.

摘要： PURPOSE:To provide a slide bearing excellent in seizure resistance, fatigue resistance and corrosive wear resistance by forming a helical corrugated protrusion in a surface of a lining material, superposing an intermediate layer composed of Ni on the surface, and further superposing an overlay layer composed of Sn alloy. CONSTITUTION:A protrusion 5a of copying protrusion 3a of a lining material 3 is formed in a slide contact surface, to set surface roughness of the lining material 3 to 2mumRz to 8mumRz, and an intermediate layer 4 is constituted of Ni. Thickness of the layer is set to 0.01 to 0.6mum, and an overlay layer 5 is constituted of 99.5% or more Sn by wt.% and the rest of part of impurities, also to set thickness of the layer to 2 to 8mum. Further, a pitch (p) of the protrusion 5a, formed in the slide contact surface, is set to 0.1 to 0.4mm, also to set height (h) of the protrusion to 2 to 8mum. In this way, seizure resistance, fatigue resistance and corrosion wearing resistance of a slide bearing can be improved.

摘要： PROBLEM TO BE SOLVED: To effectively prevent adhesion even though the diameter of a rotary shaft, the angle between crossing grooves with the peripheral direction, or pitches of grooves is/are suitably changed. SOLUTION: A grooved slide bearing is formed at least a part of its inner peripheral surface with several crossing grooves 2 with the peripheral direction. Further, the pitches and the crossing angel of the grooves 2 are set to have the following relationship therebetween: α×D/p>=3500 where D is the diameter of the rotary shaft, α is the crossing angle of the grooves with the peripheral direction, p is pitches of grooves.

摘要： PURPOSE:To control whether torque is transmitted or not by setting a space between a cover unit and a non-magnetic upper disk smaller than a space between the upper disk and a magnetic lower disk in a closed chamber, connecting both the spaces, and adjusting level height of magnetic fluid in the closed chamber to come into contact with or to approach a lower surface of the upper disk. CONSTITUTION:In a condition of demagnetizing an electromagnetic coil 15, since shear force of magnetic fluid 12 in a closed chamber 11 is generated small further with a fluid level only adjacent to a lower surface of an upper disk 3 of non-magnetic material, even when the upper disk 3 is rotated by an input shaft 1, rotational torque is not transmitted to a lower disk 4 of magnetic material and a tubular member 7, and an output shaft 2 maintains a stationary condition. When the magnetic fluid 12, lower disk 4 and a cover unit 9 are magnetize by exciting the electromagnetic coil 15, the magnetic fluid brought into contact with the lower surface of the upper disk 3 is partly circulated into a space h2 between the cover unit 9 and the upper disk 3, and a cavity is formed in the central part of a space h1 between the upper/ lower disks 3, 4. In this way, shear stress of the magnetic fluid 12 in the space between the upper disk 3 and the cover unit 9 is increased to transmit rotational torque of the input shaft 1 to the output shaft 2.

摘要： PROBLEM TO BE SOLVED: To reduce waste and a friction resistance of a sliding surface. SOLUTION: A scroll compressor 1 has a cylindrical thrust bearing 2. When a turning scroll 4 is interlockingly revolved together with a driving shaft 3, an end surface 4A of the turning scroll 4 slides on a sliding surface 2A of the thrust bearing 2. The thrust bearing 2 is formed with an annular groove 2B in a concentric circle state on the sliding surface 2A. A diameter D2 of the annular groove 2B is set to 1/3 or above of an external diameter D1 of the sliding surface 2A of the thrust bearing 2.
