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 prevent production of abnormal wear and to provide a high traction rate, by a method wherein the surface of a roller is coarsened and proper flatness is provided. CONSTITUTION:The surface of at least the one roller 12 of roller 10 and 12 is coarsened. Surface coarseness of the coarsened surface is 5mum or more in 10 point average coarseness. This constitution causes an oil film bottom to be partially divided, and since power transmission, in which a power transmission, produced by viscosity of a oil film F, is combined with power transmission produced by contact between the rollers 10 and 12, the coefficient of traction can be sharply improved.

摘要： PURPOSE:To disassemble an outer ring and an inner ring in simple manner by installing a cylindrical inner ring having a projecting spherical surface on the outer surface and a cylindrical outer ring which has a recessed spherical surface on the inner surface and the less length in the axial direction than that of the inner ring and forming an inner ring inserting and releasing groove on the outer ring. CONSTITUTION:A recessed spherical surface 11 and an inner ring inserting and releasing groove 12 having the equal outer diameter to the inner diameter of the recessed spherical surface 11 are formed on an outer ring 10. Since the thickness in the axial direction of the inner ring inserting and releasing groove 12 is set slightly larger than the thickness in the axial direction of an inner ring 20, the inner ring 20 can be inserted into the inner ring inserting and releasing groove 12 in a state where the shaft 01 of the outer ring 10 and the shaft 02 of the inner ring 20 cross. Since the outer surface of the inner ring 20 is formed in a projecting spherical surface, the inner ring 20 is inserted into the inner ring inserting and releasing groove 12, and then the inner ring 20 can be revolved, and assembly is carried out.

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 improve conformability of a belt type continuous variable transmission mechanism and also to obtain a high width accuracy as well as to obtain a high constant friction coefficient, by executing shot blast processing on the side end surface of the block of a belt type continuous variable transmission mechanism (CVT). CONSTITUTION:The space between a movable flange 1b and a fixed flange 1a is set at a value necessary for the desired speed change. The space between the opposing surfaces 1c of the flanges 1a, 1b changes as well. A block 10 is always in contact with the opposing surfaces 1c through contact inclined surfaces 10a, and this contact position changes in directon A in accordance with the change of the space D. When the block 10 is in the position necessary for the desired speed change, the rotational force necessary for speed change is transmitted to the block 10 through the contact inclined surface 10a. The side end surface of the block 10 is subjected to shot blast processing, for example, under the conditions such as air pressure of 6-8kgf/cm , nozzle diameter of 10mm., shot of 14 mesh alumina, shot period of approximately 1min. Consequently, numerous pores of depth 15-20mu are formed on the side end surfaces of the block 10.

摘要： PURPOSE:To make the efficiency of transmission high and nearly constant from the low region of transmission ratio to the high region thereof, by selectively sulfurizing the iron of a steel block except for its surfaces which come into contact with rotary members. CONSTITUTION:In a motive power transmission belt comprising a steel belt portion 18 and steel blocks 10, the iron of each steel block is selectively sulfurized except for its surfaces which come into contact with rotary members 1a, 1b. As a result, the frictional force between the steel blocks 10 is reduced to improve the efficiency of belt-type CVT transmission. Since the contact surfaces of the steel block for the rotary members 1a, 1b are not sulfurized, the coefficient of friction between the contact surfaces and the rotary members are still 0.05-0.2 so that a desired belt-type CVT torque transmission is enabled.

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.

摘要： PURPOSE:To improve transmission efficiency, by forming very fine pores on the surface of at least one of the opposing surfaces between respective belt members, respective blocks or the block and the belt member. 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.
