Abstract

PURPOSE: To obtain a sintered oil containing bearing having the dense surface layer part and thus excellent in the mechanical strength and also obtain a chain using such bearing, by forming the bearing body having the scatter preventing chamfer for the lubricating oil across the inner diameter face with the metal powder and then finishing the bearing into a prescribes size via the rolling roller after sintering.
CONSTITUTION: The powder of the Cu, Ni, Pb, Mo, Al, C, Sn, etc. is distributed to the powder of the Fe or the Fe alloy to form the bearing body A' having the scatter preventing chamfer 2 for the lubricating oil across the inner diameter face and having the outer diameter D a little larger than the desired size. The body A' is then sintered at 1,120W1,150°C and in a protective atmosphere, and this sintered substance is sent between the two rolling rollers 6 and 7 to be finished into a prescribed outer diameter. In such process, only the surface layer part 4 of the sintered bearing body (a) becomes dense extremely, thus increasing the mechanical strength. Then a cementation hardening is carried out at 880°C, and then the tempering is given at 180°C. The lubricating oil is then is impregnated to the sintered oil containing bearing body (a) thus manufactured, and then the body (a) is fitted to the chain pin shaft 9. Thus a chain having no reduction of the oil content factor for a long time is obtained.
