    摘要: Disclosed is a method for producing a mechanical part superior in rolling fatigue life. The mechanical part includes a rolling portion for a rolling element to roll along an inner diameter surface of an annular workpiece material subjected to cold forging. The method includes performing cold forging by applying a hydrostatic stress to the inner diameter surface of the annular workpiece material on which the rolling portion is to be formed, thereby forming the rolling portion on the inner diameter surface of the annular workpiece material for the rolling element to roll therealong and increasing an inner diameter of the annular workpiece material other than the rolling portion, so as to provide an annular mechanical part including the rolling portion superior in rolling fatigue life.

    摘要: This invention provided a manufacturing method to process a small-diameter step section 18 on an inside end section of a hub body 13a that comprises an outward facing flange 15 and a positioning cylinder 16 stably and with high precision. In this invention, an intermediate material 40 is pressed between a lower punch 36 and an upper punch 46 with an outer peripheral surface of the intermediate material 40 being held by a lower die 37 and an upper die 43, and then a part of the intermediate material 40 is pressed into the lower punch 36 such that the small-diameter step section 18 is formed by cold plastic working.

    摘要: A cross-roller bearing with plug, which has the high stiffness enough to allow the cross-roller bearing to turn with causing no jar or wobble, and also the production process to realize the cross-roller bearing with plug with ease and accuracy. With the cross-roller bearing with plug, more than one roller fills the space between the outside and inside races through a loading bore cut in any one of the races, and then a plug fits into the loading bore. The plug experiences cutting on its outside surface at the same time with the cutting of the circular outside surface of the outside race at once. The inside surface of the plug is also worked together with the cutting of the raceway surface around the inside circular surface of the outside race at a time.
