摘要： PURPOSE:To eliminate a change of friction force on a belt so as to stably obtain its driving power in low and high speed change sides, by providing a microholed part on a block in a continuously variable transmission mechanism of belt driven type. CONSTITUTION:In an opposed surface where a block 10 is oppositely faced to further brought into contact with a rotary member, the block 10 or said rotary member has a microholed part 20, in which a particle counter measures 5-40% area propotion and 300-150,000 holes per 1mm. further a diameter of 0.5mum or more of said holed part, further a relative load curve measured by a surface shape measuring device with a roughness analyzer has the flatness of high crest in roughness as shown by that less than 3mum for the accumulative percentage of 5% or less further that less than 2mum for the accumulative percentage exceeding 5% and less than 40%. The reason for the microholed part to be formed in the area proportion of 5-40% is that the hole, if its area proportion is less than 5%, is not effected showing a friction characteristic according to the conventional thought of roughness while the hole, if its area proportion exceeds 40%, causes transmission efficiency to be worsened.

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： PURPOSE:To obtain a sliding member excellent in wear resistance, seizing resistance and fitness by dispersing specified granular hard substances into the upper layer of an Sn base overlay provided on the surface of an Al series or Cu series bearing alloy via an intermediate layer. CONSTITUTION:The surface of an Al series or Cu series bearing alloy is provided with an overlay constituted of an Sn base bearing alloy. In this bearing material, the overlay is constituted of an upper layer in which, by volume, 5 to 50% granular hard substances are dispersed into an Sn or Sn base bearing alloy contg. >=75% Sn and a lower layer constituted of an Sn or Sn base bearing alloy in which hard substances are not dispersed. Furthermore, the average grain size of the granular hard substances is regulated to 0.1 to 5mum and whose maximum grain size is regulated to less than the thickness of an oil film. In this way, the adhesion of the overlay is made sufficiently tight, and its excellent properties are satisfactorily shown.

摘要： PURPOSE:To prevent the occurrence of fretting, to reduce the occurrence of initial wear, and to improve draping properties, fatigue resistance, and seizure resistance by a method wherein a composite plating layer formed by PTFE, Ni, and/or Co is formed on the outermost surface side of a back plate or on the outermost surface of a bearing alloy layer. CONSTITUTION:In a substance in which an aluminum or copper bearing alloy layer 2 and an overlay layer 3, where necessary, are orderly formed on the surface of a back plate 1, composite plating layers 4 and 5 of PTFE, Ni, and/or Co is formed on an outermost surface on the bearing alloy layer 2 side, on the outermost surface of the back plate 1, or the outermost surfaces of both the bearing alloy layer 2 and the back plate 2. This constitution improves adhesion of a surface on which the composite plating layer is formed, reduces a friction factor, and improves heat resistance, resulting in prevention of the occurrence of fretting. Further, this constitution improves draping properties, reduces the occurrence of initial wear through the action of the draping properties, and improves wear resistance through the presence of Ni and the like.

摘要： PURPOSE:To improve the quietness of a floating bearing and cut cost by forming the sliding surface of the inner and outer surfaces of a bush from the contact surface between the metallic material and resin material. CONSTITUTION:When a relative revolution is generated between the outer ring 11 and inner ring 12 of a floating bearing, a bush 13 made of resin slide- contacts the inner peripheral surface of the cylindrical part 11a of a metal outer ring 11 and the outer peripheral surface of a metal inner ring 12. Since the sliding contact is generated through the contact between the metallic material and resin material, superior sliding characteristic can be obtained, and the generation of galling and abrasion can be prevented. Therefore, quietness of the bearing can be improved, and also the structure can be made simple, and the number of constitution parts can be reduced, and cost cut can be realized.

CONSTITUTION:Fine pores 20 are formed on the surface 101 where blocks are in contact with each other, and on the hoop-passing surfaces 10c. The fine pores should favourably have area rate 5-40%, diameter between 5-100mum. Their number should be 300-6,000/mm. . Regarding the relative load curve cumulative percentage, those less than 5% are under 2 and those more than 5% and under 40% are under 1.5mm.. The upper limit of the depth of the fine pores is 10mum whereas its lower limit is 0.5mum.
