Abstract

PURPOSE:To enable dynamic pressure generating surface shape to be efficiently transferred to a separate member surface by using the dynamic pressure generating surface produced by prior art with high precision for master cam. CONSTITUTION:To work a work 6 attached to a master cam 1, a cylindrical working surface of a tool 8 rotating in the direction of arrow f is adapted to coincide with the radial direction of an annular work and then the tool 8 is fed in the work 6 by a predetermined amount. Next, when the master cam 1 is rotated in the direction of arrow e about the axis 20 by a handle 9, the cam surface 2 contacting a fixed contact point 4 is moved to vary the height of the work according to the respective vertical positions of the cam surface 2. Since here the height of working surface of the tool 8 is not changed, the shape of the cam surface 2 is transferred to the worked surface of the work 6.

もつ。Figure 81 shows an example of a dynamic pressure thrust plate. /' is a helical dynamic pressure generating surface whose height increases in proportion to the rotation angle; in FIG. 1, there are six dynamic pressure generating surfaces of the same height in seven turns.

かかる欠点があつた。Conventionally, methods for obtaining such a dynamic pressure generating surface include finishing the annular end face by hand, using a combination of a thread cutting lathe and a race grinder, and grinding the cylindrical end face according to the thread cutting speed of the lathe. There is a method in which a cut is made by a lace grinder, and the cut position of the lace grinder is adjusted each time one partial helical surface is processed. In the former case, although the degree of inclination of the helical surface relative to the rotation angle can be processed arbitrarily, the processing time is extremely long and it is difficult to achieve high finishing accuracy. In the latter, the degree of inclination with respect to the rotation angle of the helical surface is determined by the feed rate per revolution of the lathe, and the degree of inclination cannot be selected continuously in a normal lathe. In addition, it was necessary to adjust the cutting position of the lace grinder for each slope/fall, which resulted in a drawback that the machining time was increased accordingly.
