摘要： PURPOSE:To enhance circularity accuracy of a boss portion so as to aim at improvement in quality of a sintered part by providing a clearance portion in a part of a tooth portion in a section of defective circularity caused by distortion in such a way that the pressing force of a chuck device isn't applied thereto so as to chuck the sintered part. CONSTITUTION:A clearance portion 8 is formed in a part of a tooth portion in a section of defective circularity caused by distortion in such a way as to produce a gap between the clearance portion 8 and a chuck device 6. Since lowering a tooth height may produce the gap, the mold of a sintered part is previously formed in such a way as to be molded into the shape. The tooth height of the clearance portion 8 at this time is enough if the chuck device 6 isn't allowed to abut thereto at the time of chucking. In this way, a planetary carrier 1 is chucked in such a way that the clearance portion 8 is formed in the section of defective circularity caused by distortion, so as to enhance virtual circularity. Therefore, the elastic deformation of a boss portion 4 at the time of chucking can be reduced, thereby enhancing the circularity after lathe turning.

摘要： PURPOSE: To mold and fix directly an optional number of green compact moldings at an optional position to a hollow shaft member which is hermetically sealed in the hollow part by using a cylindrical rubber mold, disposing the shaft material into the lower aperture of the rubber mold and packing a raw material of metallic powder for powder metallurgy therein.
CONSTITUTION: The hollow shaft material 10a of which the hollow part 10b is hermetically sealed by a hermetic sealing member 6a is disposed in the lower aperture of the rubber mold 3 and the raw material 5 of the metallic powder for powder metallurgy is packed therein. The material 10a of which the hollow part 10b is hermetically sealed by the member 6a is raised into the lower aperture of the mold 3 and the material 5 is allowed to remain only in the molding cavity C for the green compact molding. The material 5 is then hydrostatically pressurized to form the green compact molding by which said molding is directly molded and fixed to the material 10a.

摘要： PURPOSE: To mold and fix directly a green compact molding to a shaft member at different phases by forming a recessed or projecting part engaging with a projecting or recessed part formed to the shaft material to one end of members for mounting the shaft material.
CONSTITUTION: The hollow shaft material 1a mounted to the upper and lower members 5, 7 for mounting the shaft material is made freely rotatable and movable by the member 5 connected to a rotational driving mechanism 6 and is made freely vertically movable by a hydraulic cylinder. The projecting part 5a of the member 5 is engaged with the U groove 1b of the central shaft member 1. A molding die 3 is mated and fixed into a block 8 so as to comply with the position of the material 1a to be directly formed and fixed with the green compact molding 2. A raw material of metallic powder for powder metallurgy is packed into a cylindrical cavity 3a and an upper punch 4 is lowered to mold the raw material by compaction by which the green compact molding 2 is directly molded and fixed to the shaft material 1a.

摘要： PURPOSE: To directly mold and fix plural compacts to arbitrary positions of a shaft material inexpensively and with high productivity, by inserting the shaft material into a rubber mold having protruded parts, and pressing a metal powder material for powder metallurgy packed in the protruded parts hydrostatically.
CONSTITUTION: The rubber mold 3 opened at both ends, having cylindrical inner surface shape and the protruded parts 3b is fitted in a pressure vessel 4 vertically. Next, inside of the vessel 4 is pressed so that a shape size d
2 of a pressing position 3a of the shaft material 5 of the mold 3 is made equal to an outer circumferential size D
1 of the material 5. The metal powder material 6 for powder metallurgy is packed in the mold 3 in said state, then the material 5 is rised to opened upper hold part from opened under hole part of the mold 3, so that the material 6 remains in a cavity C formed by the part 3b and the excess quantity is excluded. Next, inside of the vessel 4 is pressed hydrostatically by high pressure, to mold and fix the compact 7 to the material 5. Thereafter, pressure is released to take out the shaft material to which the compacts 7 are fixed to prescribed position.
