摘要： There is provided a sintered metallic alloy having toughness capable of supporting stress at a point by distributing structure portions having different values of rigidity approximately uniformly without separation of layers different in brashiness. A method of manufacturing the sintered metallic alloy and a sintered alloy gear employing the sintered metallic alloy are also provided. Metallic materials are formed into a predetermined configuration. Then, the metallic materials is sintered in a sintering furnace (14) to make a sintered metallic alloy. Next, the sintered metallic alloy is cooled gradually to an ambient atmosphere of room temperature. Finally, the temperature of the cooled metallic alloy is raised and a toughness stabilizing process is performed in a low-temperature furnace (18) so that structures with high toughness are distributed approximately uniformly.

摘要： The internal gear is a bottomed cylindrical component, which has the boss portion fitted over the outer circumferential surface of the shaft, the disk-shaped flange portion extending radially outwardly from the boss portion, and the cylindrical gear body having a tooth portion in its inner circumferential surface and connecting integrally to the outer circumferential part of the flange portion. The flange portion is virtually conical on its outer side surface and tapered from the outer diameter side toward the inner diameter side, i.e., from the gear body toward the boss portion. This construction is thicker at the boss portion side than at the gear body side. Further, the density of the flange portion is almost inversely proportional to the thickness and is lower at the boss portion side than at the gear body side. The cylindrical gear body has a density distribution such that the central part of the gear body is lower in density than the end portions in a tooth trace direction of the teeth portions.

摘要： In a planetary gear set, a pinion shaft extending through one of planetary pinions has one and opposite end portions supported by two spaced plate portions of a carrier. Needle bearings are disposed between the pinion and the pinion shaft. Pinion washers extend around the piston shaft and radially between the pinions and the adjacent plate portions of the carrier. In order to withstand a thrust which the needle bearings are subjected to, the pinion washers have integral portions extending axially into spaces defined between the pinion, the needle bearings and the spaced plate portions of the carrier. Alternatively, the pinion shaft may have integral portions extending radially into the spaces.

摘要： A method for producing a washer having a boss comprises the following steps in the sequence set forth: (a) sprinkling powder of a bearing alloy onto a backing metal made of an iron-based alloy to form a composite material; (b) sintering the composite material to obtain a bimetal material so as to accomplish a primary sintering; (c) fabricating the bimetal material into a shape of the washer having the boss; and (d) simultaneously accomplishing a secondary sintering and carburizing of the washer having the boss. By virtue of simultaneously conducting the secondary sintering and the carburizing for the washer, the number of steps in producing method (particularly, during a heat treatment) is reduced thereby improving the productivity of the washer having the boss while reducing thermal energy required for the heat treatment.

摘要： A lubricating structure of an automatic transmission is provided which is capable of realizing sufficient cooling lubrication with lubricating oil, utilizing a given space efficiently, and avoiding the possibility of an increase in the weight of assembly parts by checking an increase in the number of the assembly parts. The rotational direction of a front planetary gear device (46) and the like is changed by engagement or disengagement of each of multiplate clutch plates (35, 43) of a plurality of multiplate clutch devices (33, 40), and thereby the transmission state of driving force is shifted. A 2-4 brake clutch (33) of the multiplate clutch devices (33, 40) is engaged in two forward gears and is disengaged in a forward gear between the two forward gears. A reverse clutch (40) of the multiplate clutch devices (33, 40) is disposed substantially in the same position as that of the 2-4 brake clutch (33) in the axial direction and outside of the 2-4 brake clutch (33) in the radius direction. The reverse clutch (40) uses a clutch drum (36) of the 2-4 brake clutch (33) as a clutch hub.
