Abstract
A method for manufacturing a porous oil-impregnated revolving shaft assembly includes following steps: 1) offering an amount of metal powder, a particle diameter of the metal powder ranging from 1 μm to 150 μm; 2) offering a mold cavity and filling the metal powder in the mold cavity to form a green piece, a plurality of pores being defined between the metal powder of the green piece; 3) heating the green piece at a high temperature to sinter the metal powder to obtain a sintered product, a volume ratio of pores of the sintered product ranging from 12% and 20%; 4) dipping the sintered product into oil to make the oil enter the pores of the sintered product to thereby obtain a final desired product for forming the porous oil-impregnated revolving shaft assembly.
