摘要： PURPOSE:To purify engine oil by burying very small foreign matters mixed in engine oil into the slide bearing. CONSTITUTION:A great number of projections extended in the circumferential direction are formed in the slide and contact surface 1A of the slide bearing 1, and the slide and contact surface is practically formed up by the apex sections 1a' of the respective projections 1a. In a state that a rotating shaft is rotatably supported, engine oil permeates into the slide and contact surface 1A of the slide bearing 1, in this case, very small foreign matters roughly 1mum in size contained in engine oil are buried in the apex sections 1a' of the projections 1a so as to be removed out of engine oil. Therefore, engine oil can thereby be purified by the slide bearing 1.

摘要： PURPOSE:To provide seizure resistance and conformability of a bearing more excellent than in the past by applying an annular groove to a bearing alloy layer, forming this section wavy, and setting a relation between height of this mountain part and thickness of an adjacent intermediate layer to a specific range. CONSTITUTION:In a slide bearing 1, a bearing alloy layer 2 is provided on a back plate, and a helical annular groove 2a is formed along a circumferential direction, to form a ridge, prepared by the annular groove 2a adjacent in the axial direction, as a mountain part 2b. This mountain part is covered with an intermediate layer 3, further to superpose an overlay layer 4. At the time of actual use, in the case that partly the overlay layer 4 and intermediate layer 3 are worn from a surface side of the overlay layer 4, as shown by a vertual line L in the drawing, the overlay layer 4, intermediate layer 3 and the mountain part 2a of the bearing alloy layer 2 are respectively exposed. Here, when assumed (h) for height of the mountain part 2b and (t) for thickness of the intermediate layer 3, a conditional formula of relation where 1

摘要： PURPOSE:To obtain stable formation of a wedge layer of lubricant gas by providing a plurality of top foils along the top of bump foils and giving each top foil a slope corresponding to a gradient of change in depth of recessed portions. CONSTITUTION:Top foils 15 are provided along the top of bump foils 14. When a rotating member 12 is rotated in a direction of an arrow A, the portion of the top foil 15 brought in contact with a bump portion 14a is given a slope corresponding to a gradient of recessed portions 13. The portion of the top foil 15 on a thrust surface 11a of a bearing member 11 is substantially in parallel to the thrust surface 11a and the end surface 12a of the rotating member 12. This causes a wedge layer of lubricant gas to be stably formed between the top foils 15 and the end surface 12a of the rotating member.

摘要： PURPOSE:To improve resistance against seizure and wear of a slide bearing, by forming irregularities on the surface of a lining member made of aluminum- alloy, covering the inner surface of hollows of said irregularities with an adherent layer, and finally forming a overlaying layer over said irregular surface. CONSTITUTION:The surface of a lining member 1 made of aluminum-alloy are made to form irregularities which include hollows 2, and an adherent layer 3 is formed over said irregularities, said layer 3 being made of plating consisting of Ni, Cu or the like. In addition, over the surface of said adherent layer 3, an overlaying layer of Pb-alloy 4 is formed filling said hollows 2 with its surface becoming a plain sliding surface. Due to the above construction, improvement of a running-in characteristic, relieving of uneven face-contact, and reduction of friction can be attained by said over-laying layer 4 when a sliding bearing is started to be used, while good resistance against seizure and wear can be held even when said adherent layer 3 and said over-laying layer 4 are worn out to the prominent areas of the surface of said lining member 1.

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.
